remove alternate brand names from the product label.
Product Name: MON 89034 x MON 88017
EPA Registration Number: 524-576
Submission Date: September 7, 2018
OPP Decision Number: 544525
Dear Mr. Chi:
The amendment referenced above, submitted in connection with registration under Section 3(c)(7)(A) of the
Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), is acceptable provided that you comply with
the updated terms and conditions as described in this letter.
1. The subject registration will automatically expire at midnight on December 31, 2020.
2. Monsanto must adhere to the transition strategy detailed in its submission titled “Amended Phase Out
Plan for MON 89034 x MON 88017 (VT Triple PRO®)” (dated September 7, 2018) (MRID: 506395-
02).
3. The subject registration will be limited to the subject registration will be limited to Bacillus
thuringiensis Cry1A.105 and Cry2Ab2 proteins and the genetic material necessary for their production
(vector PVZMIR245) in MON 89034 corn (OECD Unique Identifier: MON-8934-3 x MON-8817-
3) and Bacillus thuringiensis Cry3Bb1 protein and the genetic material necessary for its production
(vector PV-ZMIR39) in MON 88017 corn (OECD Unique Identifier: MON-8934-3 x MON-8817-3)
for use in field corn.
4. Submit and/or cite all data required for registration or registration review of MON 89034 x MON 88017
when the EPA requires all registrants of similar products to submit such data.
5. This plant-incorporated protectant (PIP) may be combined through conventional breeding with other

EPA Reg. No. 524576 
OPP Decision No. 544525   
6. Monsanto must commit to do the following Insect Resistance Management (IRM) Program, consisting
of the following elements:
 Requirements for Monsanto to implement an IPM-based stewardship program designed to
reduce selection pressure for corn rootworm (CRW) resistance.
 Requirements relating to creation of a refuge for the Cry3Bb1, Cry1A.105, and Cry2Ab2
components that meets the requirements of the individual traits. The refuge for both traits may
be combined by planting non-Bacillus thuringiensis (Bt) corn as the refuge, or the refuge for
each trait may be planted separately. In the latter case, corn rootworm-resistant Bt corn may be
planted in the lepidopteran refuge for the Cry1A.105 and Cry2Ab2 components, and
lepidopteran-resistant Bt corn may be planted in the corn rootworm refuge for the Cry3Bb1
component.
 Requirements for Monsanto to prepare and require MON 89034 x MON 88017 users to sign
grower agreements that impose binding contractual obligations on growers to comply with the
refuge requirements.
 Requirements for Monsanto to develop, implement, and report to EPA on programs to educate
growers about IRM requirements.
 Requirements for Monsanto to develop, implement, and report to EPA on programs to evaluate
and promote growers compliance with IRM requirements.
 Requirements for Monsanto to develop, implement, and report to EPA on monitoring programs
to evaluate whether there are statistically significant and biologically relevant changes in
susceptibility to the Cry1A.105 and Cry2Ab2 proteins in the target insects.
 Requirements for Monsanto to develop, and if triggered, to implement a remedial action plan
that would contain measures Monsanto would take in the event that any field-relevant insect
resistance to Cry1A.105 and/or Cry2Ab2 was detected, as well as to report on activity under
the plan to EPA.
 Requirements for Monsanto to investigate reports of unexpected CRW damage to MON 89034
x MON 88017 from growers (“performance inquiries”) and sample CRW to determine if the
insects are resistant to Cry3Bb1.
 Requirements for Monsanto to recommend CRW management options to growers in response
to cases of unexpected CRW damage to MON 89034 x MON 88017.
 Requirements regarding mitigation and notification actions that Monsanto would take in
the event that CRW resistance is detected.
 Requirements for Monsanto to maintain, and provide the Agency upon request, the number
of units sold by state and county, IRM grower agreement results, and substantive changes to
educational programs. Monsanto is required to submit reports within three months of the
Agencys request.

EPA Reg. No. 524576 
OPP Decision No. 544525   
 Bag Tag Requirements for MON 89034 x MON 88017. Seed bags and/or bag tags for corn
hybrids that contain plant- incorporated protectants produced in MON 89034 x MON 88017
must display the registration number and active ingredients, and stipulate that growers read the
Monsanto Stewardship Guide (or equivalent guidance) prior to planting these hybrids. The
refuge size requirement must be displayed on the bag or bag tag in both text and graphic
format.
 Requirements for Monsanto, on or before August 31st of each year, to submit reports on
Cry1A.105 and Cry2Ab2 resistance monitoring.
a. Integrated Pest Management Stewardship Program
1. Monsanto must implement an IPM-based stewardship program for MON 89034 x MON 88017. This
program must be designed to reduce selection pressure for corn rootworm (CRW) resistance by encouraging
growers to engage in a multi-year crop rotation strategy involving the use of one or more of the following: a
non-CRW host crop (e.g., soybean), pyramided Bt corn Plant Incorporated Protectants (PIPs), other PIP
corn products with different modes of action, and/or non-Bt or non-CRW protected Bt corn. As part of the
stewardship program, Monsanto must update the technology use guide/grower guide and other grower
educational materials to indicate that application of an insecticide to the soil surface, in furrows, and/or
incorporated into the soil (referred to as “soil applied insecticide”, “soil insecticide” or “SAI”) with MON
89034 x MON 88017 is not recommended for control of CRW except under limited circumstances and in
consultation with extension, crop consultants or other local experts. As part of the stewardship program,
Monsanto must promote the ABSTC/NCGA Best Management Practices (BMPs) for CRW control.
Implementation of the IPM strategy can include:
 Grower education initiatives or incentives.
 Outreach to extension and consultant groups.
2. Monsanto must submit an annual report to EPA documenting activities conducted under the IPM
stewardship program. This report must include an anonymous survey of grower practices, including
adoption levels of the various crop rotation options (if employed) and other elements of the stewardship
program. Monsanto may combine this product with other registered products to submit one annual report.
The report must be submitted by January 31
st each year.
b. Refuge Requirements for MON 89034 x MON 88017
These refuge requirements do not apply to seed increase/propagation of inbred and hybrid seed corn up to a
total of 20,000 acres per county and up to a combined United States (U.S.) total of 250,000 acres per plant
incorporated protectant (PIP) active ingredient per registrant per year.
Grower agreements (also known as stewardship agreements) will specify that growers must adhere to the refuge
requirements as described in the grower guide/product use guide and/or in supplements to the grower
guide/product use guide.
1) Corn-Belt Refuge Requirements
For MON 89034 x MON 88017 grown outside cotton-growing areas (e.g., the Corn Belt), grower agreements
(also known as stewardship agreements) will specify that growers must adhere to the refuge requirements as
Page 4 of 20 
EPA Reg. No. 524576 
OPP Decision No. 544525   
described in the grower guide/product use guide and/or in supplements to the grower guide/product use guide.
Two options for the deployment of the refuge are available to growers.
The first option is planting a common refuge for both corn borers and corn rootworms. The common refuge
must be planted with corn hybrids that do not contain Bt technologies for the control of corn rootworms or corn
borers. The refuge area must represent at least 20% of the growers corn acres (i.e., sum of MON 89034 x MON
88017 acres and refuge acres). It must be planted as a block adjacent to the MON 89034 x MON 88017 field,
perimeter strips, or in-field strips. If perimeter or in-field strips are implemented, the strips must be at least 4
consecutive rows wide. The common refuge may be treated with a soil-applied or seed-applied insecticide to
control rootworm larvae and other soil pests. The refuge may also be treated with a non-Bt foliar insecticide for
control of late season pests if pest pressure reaches an economic threshold for damage (determined using
methods recommended by local or regional professionals); however, if rootworm adults are present at the time
of foliar applications, then the MON 89034 x MON 88017 field must be treated in a similar manner.
The second option is planting separate refuge areas for corn borers and corn rootworms. The corn borer refuge
must be planted with a non-Bt/lepidopteran-protected hybrid, must represent at least 5% of the growers corn
acres (i.e. sum of MON 89034 x MON 88017 acres and corn borer refuge acres), and must be planted within ½
mile of the MON 89034 x MON 88017 field. Refuge planting options include: separate fields, blocks within
fields (e.g., along the edges or headlands), perimeter strips, or in-field strips. If perimeter or in-field strips are
implemented, the strips must be at least 4 consecutive rows wide. The corn borer refuge may be treated with a
soil-applied or seed-applied insecticide for corn rootworm larval control or a non-Bt foliar-applied insecticide
for corn borer control if pest pressure reaches an economic threshold for damage (determined using methods
recommended by local or regional professionals). The corn rootworm refuge must be planted with a non-Bt/corn
rootworm-protected hybrid but may be planted with Bt corn hybrids that control corn borers. The corn
rootworm refuge must represent at least 20% of the growers corn acres (i.e. sum of MON 89034 x MON 88017
acres and corn rootworm refuge acres) and must be planted as an adjacent block, perimeter strips, or in-field
strips. If perimeter or in-field strips are implemented, the strips must be at least 4 consecutive rows wide. The
corn rootworm refuge may be treated with a soil-applied or seed- applied insecticide to control rootworm larvae
and other soil pests. The refuge may also be treated with a non-Bt foliar insecticide for control of late season
pests; however, if rootworm adults are present at the time of foliar applications, then the MON 89034 x MON
88017 field must be treated in a similar manner.
2) Cotton-Growing Area Refuge Requirements
For MON 89034 x MON 88017 grown in cotton-growing areas, grower agreements (also known as stewardship
agreements) will specify that growers must adhere to the refuge requirements as described in the grower
guide/product use guide and/or in supplements to the grower guide/product use guide.
Cotton-growing areas include the following states: Alabama, Arkansas, Georgia, Florida, Louisiana, North
Carolina, Mississippi, South Carolina, Oklahoma (only the counties of Beckham, Caddo, Comanche, Custer,
Greer, Harmon, Jackson, Kay, Kiowa, Tillman, Washita), Tennessee (only the counties of Carroll, Chester,
Crockett, Dyer, Fayette, Franklin, Gibson, Hardeman, Hardin, Haywood, Lake, Lauderdale, Lincoln, Madison,
Obion, Rutherford, Shelby, and Tipton), Texas (except the counties of Carson, Dallam, Hansford, Hartley,
Hutchinson, Lipscomb, Moore, Ochiltree, Roberts, and Sherman), Virginia (only the counties of Dinwiddie,
Franklin City, Greensville, Isle of Wight, Northampton, Southampton, Suffolk City, Surrey, Sussex), and
Missouri (only the counties of Dunklin, New Madrid, Pemiscot, Scott, and Stoddard).
Two options for the deployment of the refuge are available to growers.

The first option is planting a common refuge for both corn borers and corn rootworms. The common refuge
must be planted with corn hybrids that do not contain Bt technologies for the control of corn rootworms or corn
borers. The refuge area must represent at least 20% of the growers corn acres (i.e. sum of MON 89034 x MON
88017 acres and refuge acres). It must be planted as a block adjacent to the MON 89034 x MON 88017 field,
perimeter strips, or in-field strips. If perimeter or in-field strips are implemented, the strips must be at least 4
consecutive rows wide. The common refuge may be treated with a soil-applied or seed-applied insecticide to
control rootworm larvae and other soil pests. The refuge may also be treated with a non-Bt foliar insecticide for
control of late season pests if pest pressure reaches an economic threshold for damage (determined using
methods recommended by local or regional professionals); however, if rootworm adults are present at the time
of foliar applications, then the MON 89034 x MON 88017 field must be treated in a similar manner.
The second option is planting separate refuge areas for corn borers and corn rootworms. The corn borer refuge
must be planted with a non-Bt/lepidopteran-protected hybrid, must represent at least 20% of the growers corn
acres (i.e. sum of MON 89034 x MON 88017 acres and corn borer refuge acres), and must be planted within ½
mile of the MON 89034 x MON 88017 field.
Refuge planting options include: separate fields, blocks within fields (e.g., along the edges or headlands),
perimeter strips, or in-field strips. If perimeter or in-field strips are implemented, the strips must be at least 4
consecutive rows wide. The corn borer refuge may be treated with a soil- applied or seed-applied insecticide for
corn rootworm larval control or a non-Bt foliar-applied insecticide for corn borer control if pest pressure reaches
an economic threshold for damage (determined using methods recommended by local or regional
professionals). The corn rootworm refuge must be planted with a non-Bt/corn rootworm-protected hybrid but
may be planted with Bt corn hybrids that control corn borers. The corn rootworm refuge must represent at least
20% of the growers corn acres (i.e. sum of MON 89034 x MON 88017 acres and corn rootworm refuge acres)
and must be planted as an adjacent block, perimeter strips, or in-field strips. If perimeter or in-field strips are
implemented, the strips must be at least 4 consecutive rows wide. The corn rootworm refuge may be treated
with a soil-applied or seed-applied insecticide to control rootworm larvae and other soil pests. The refuge may
also be treated with a non-Bt foliar insecticide for control of late season pests; however, if rootworm adults are
present at the time of foliar applications then the MON 89034 x MON 88017 field must be treated in a similar
manner.
c. Grower Agreements for MON 89034 x MON 88017
1. Persons purchasing MON 89034 x MON 88017 must sign a grower agreement. The term grower
agreement refers to any grower purchase contract, license agreement, or similar legal document.
2. The grower agreement and/or specific stewardship documents referenced in the grower agreement must
clearly set forth the terms of the current IRM program. By signing the grower agreement, a grower must be
contractually bound to comply with the requirements of the IRM program.
3. Monsanto must continue to integrate this registration into the current system used for its other Bt corn
plant- incorporated protectants, which is reasonably likely to assure that persons purchasing MON 89034 x
MON 88017 will affirm annually that they are contractually bound to comply with the requirements of the
IRM program.
4. Monsanto must continue to use its current grower agreement for MON 89034 x MON 88017. If Monsanto
wishes to change any part of the grower agreement or any specific stewardship documents referenced in
the grower agreement that would affect either the content of the IRM program or the legal enforceability of
the provisions of the agreement relating to the IRM program, then thirty (30) days prior to implementing a
Page 6 of 20 
EPA Reg. No. 524576 
OPP Decision No. 544525   
proposed change, Monsanto must submit to EPA the text of such changes to ensure that it is consistent
with the terms and conditions of this amended registration.
5. Monsanto shall maintain records of all MON 89034 x MON 88017 grower agreements for a period of three
(3) years from December 31st of the year in which the agreement was signed.
6. Monsanto shall make available to the Agency upon request records of the number of units of MON 89034
x MON 88017 seed sold or shipped and not returned, and the number of such units that were sold to
persons who have signed grower agreements for the previous growing season. Monsanto is required to
submit reports within three months of the Agencys request.
7. Monsanto must allow a review of the grower agreements and grower agreement records by EPA or by a
State pesticide regulatory agency if the State agency can demonstrate that confidential business
information, including names, personal information, and grower license numbers of the growers, will be
protected.
d. IRM Education and IRM Compliance Monitoring Program for MON 89034 x MON 88017
1. Monsanto must implement and enhance (as set forth in paragraph 17 of this section) a comprehensive,
ongoing IRM education program designed to convey to MON 89034 x MON 88017 users the importance
of complying with the IRM program and guidance to growers on actions to take when unexpected damage
occurs. The program shall include information encouraging MON 89034 x MON 88017 users to pursue
optional elements of the IRM program relating to refuge configuration and proximity to MON 89034 x
MON 88017 fields. The education program shall involve the use of multiple media, e.g. face-to-face
meetings, mailing written materials, EPA-reviewed language on IRM requirements on the bag or bag tag,
and electronic communications such as by internet, radio, or television commercials. The program shall
involve at least one written communication annually to each MON 89034 x MON 88017 user separate
from the grower technical guide. The communication shall inform the user of the current IRM
requirements. Monsanto shall coordinate its education program with the educational efforts of other
registrants and other organizations, such as the National Corn Growers Association and state extension
programs.
2. Monsanto shall revise, and expand as necessary, its education program to take into account the information
collected through the compliance survey, required under paragraphs 69 of this section, and from other
sources. The changes shall address aspects of grower compliance that are not sufficiently high.
3. Upon EPA request, Monsanto shall provide copies of grower education materials and information on
grower education activities including any substantive changes to these materials and activities conducted
either individually or as part of the industry working group Agricultural Biotechnology Stewardship
Technical Committee (ABSTC). Monsanto is required to submit reports within three months of the
Agencys request. The required features of the compliance assurance program are described in paragraphs
422 of this section.
4. Monsanto must implement and improve an ongoing IRM compliance assurance program designed to
evaluate the extent to which growers purchasing MON 89034 x MON 88017 are compliant with the
requirement of a 20% refuge for lepidopteran pests in cotton growing areas, and that takes such actions as
are reasonably needed to assure that growers who have not complied with the program either do so in the
future or lose their access to Monsantos Bt corn products. Monsanto shall coordinate with other Bt corn
Page 7 of 20 
EPA Reg. No. 524576 
OPP Decision No. 544525   
registrants in improving its compliance assurance program and integrate this registration into the current
compliance assurance program used for its other Bt corn plant-incorporated protectants. Other required
features of the program are described in paragraphs 522 of this section.
5. Monsanto must maintain and publicize a phased compliance approach (i.e., a guidance document that
indicates how it will address instances of non-compliance with the terms of the IRM program and general
criteria for choosing among options for responding to any non-compliant growers after the first year of
non-compliance). While recognizing that for reasons of difference in business practices there are needs for
flexibility between different companies, Monsanto must use a consistent set of standards for responding to
non-compliance. An individual grower found to be significantly out of compliance two (2) years in a row
would be denied access the next year to Monsantos Bt corn products for which the grower is required to
plant a separate structured refuge. Similarly, seed dealers who are not fulfilling their obligations to
inform/educate growers of their IRM obligations will lose their opportunity to sell Bt corn.
6. The IRM compliance assurance program shall include an annual survey, conducted by an independent third
party, of a statistically representative sample of growers MON 89034 x MON 88017. The survey shall be
conducted in odd-numbered years beginning in 2019 and shall include growers who plant 100 or more
acres of corn in the Southern U.S. corn-cotton areas. Monsanto may collaborate with other registrants of Bt
corn [for example, through the industry working group the Agricultural Biotechnology Stewardship
Technical Committee (ABSTC)] to conduct the survey.
In the U.S. Corn Belt, no anonymous grower survey is required for MON 89034 x MON 88017 if
Monsanto can demonstrate that the industry-wide adoption of integrated refuge products (i.e., refuge seed
blends) is equal to or greater than 70% of Bt corn acres in the Corn Belt. If industry- wide adoption of
integrated refuge products (i.e., refuge seed blends) falls below 70% of Bt corn acres in the Corn Belt, an
anonymous grower survey shall also be conducted in this region during the next growing season using a
statistically representative sample of growers who plant 200 or more acres of corn, and grower surveys
shall be continued every odd-numbered year until the industry-wide adoption of integrated refuge products
(i.e., refuge seed blends) is again equal to or greater than 70% of Bt corn acres in this region. Monsanto
may collaborate with other registrants of Bt corn (for example, through the industry working group the
ABSTC) to compile the integrated refuge adoption data and to conduct the surveys.
Alternatively, if Monsanto is not a participant of an industry working group (e.g., the ABSTC) and
Monsantos sales of integrated refuge products are equal to or greater than 70% of Monsantos total Bt corn
sales in the prior year, then no anonymous grower survey is required in the U.S. Corn Belt. If Monsantos
sales of integrated refuge products fall below 70% of Monsantos total Bt corn sales, an anonymous grower
survey shall also be conducted in this region during the next growing season using a statistically
representative sample of growers who plant 200 or more acres of corn, and grower surveys shall be
continued every odd-numbered year until sales of integrated refuge products (i.e., refuge seed blends) are
again equal to or greater than 70% of Monsantos total Bt corn sales in this region.
 A third party is classified as a party other than the registrant, the grower, or anyone else with a
direct interest in IRM compliance for Bt corn.
7. The survey shall be designed to provide an understanding of any difficulties growers encounter in
implementing IRM requirements. An analysis of survey results must include the reasons, extent, and
potential biological significance of any implementation deviations.
8. The survey shall be designed to obtain grower feedback on the usefulness of specific educational tools and
Page 8 of 20 
EPA Reg. No. 524576 
OPP Decision No. 544525   
initiatives.
9. In years in which the survey is conducted, Monsanto shall provide a final written summary of the results of
the survey (together with a description of the regions, the methodology used, and the supporting data) to
EPA on or before January 31st of the following year. Monsanto shall confer with other registrants and EPA
on the design and content of the survey prior to its implementation.
10. Monsanto shall revise, and expand as necessary, its compliance assurance program to take into account the
information collected through the compliance survey, required under paragraphs 69 of this section, and
from other sources. The changes shall address aspects of grower compliance that are not sufficiently high.
Monsanto must confer with EPA prior to adopting any changes.
11. Monsanto shall conduct and enhance an annual on-farm assessment program. Monsanto shall train its
representatives who make on-farm visits with MON 89034 x MON 88017 growers to perform assessments
of compliance with IRM requirements. There is no minimum corn acreage size for this program. Therefore,
growers will be selected for this program from across all farm sizes. In the event that any of these visits
result in the identification of a grower who is not in compliance with the IRM program, Monsanto shall
take appropriate action, consistent with its phased compliance approach, to promote compliance.
12. Monsanto shall implement a program for investigating legitimate tips and complaints that MON 89034 x
MON 88017 growers are not in compliance with the IRM program. Whenever an investigation results in
the identification of a grower who is not in compliance with the IRM program, Monsanto shall take
appropriate action, consistent with its phased compliance approach.
13. If a grower, who purchases MON 89034 x MON 88017 for planting, was specifically identified as not
being in compliance during the previous year, Monsanto shall visit with the grower and evaluate whether
the grower is in compliance with the IRM program for the current year.
14. Annually, by January 31st each year, Monsanto must provide a report to EPA summarizing the MON
89034 x MON 88017 compliance assurance program activities and results for the prior year and plans for
the MON 89034 x MON 88017 compliance assurance program for the current year. Within one month of
submitting this report to EPA, the registrant shall meet with EPA to discuss its findings. The report must
inform EPA of the number of growers deemed ineligible to purchase Bt corn seed on the basis of continued
non-compliance with the insect resistance management refuge requirements. Monsanto may elect to
coordinate information with other registrants and report collectively the results of compliance assurance
programs.
15. Monsanto and the seed corn dealers for Monsanto must allow a review of the compliance records by EPA
or by a State pesticide regulatory agency if the State agency can demonstrate that confidential business
information, including the names, personal information, and grower license numbers of the growers, will
be protected.
16. Monsanto shall revise and expand its existing Compliance Assurance Program to include the following
elements. The registrant may coordinate with other registrants in designing and implementing its
Compliance Assurance Program.
17. Monsanto will enhance the refuge education program throughout the seed delivery channel.
 Ensure sales representatives, licensees, seed dealers, and growers recognize the importance of
Page 9 of 20 
EPA Reg. No. 524576 
OPP Decision No. 544525   
correct refuge implementation and potential consequences of failure to plant the required refuge.
 Implement a “bag tag” that will be attached to all bags of MON 89034 x MON 88017 seed sold
and delivered. The PIP product label accepted by EPA must include how this information will be
conveyed to growers via text and graphics.
18. Monsanto will focus the majority of on-farm assessments on regions with the greatest risks for resistance:
 Use Bt corn adoption, pest pressure information, and other available information to identify
regions where the risk of resistance is greatest.
 Focus approximately two-thirds of on-farm assessments on these regions, with the remaining
assessments conducted across other regions where MON 89034 x MON 88017 is used.
19. Monsanto will use its available MON 89034 x MON 88017 sales records and other information to refine
grower lists for on-farm assessments of their compliance with refuge requirements:
 Identify for potential on-farm assessment growers whose sales information indicates they have
purchased MON 89034 x MON 88017 product but may have purchased little or no refuge seed
from the registrant, licensee, or affiliated company.
20. Monsanto will contract with third parties to perform on-farm assessments of compliance with refuge
requirements:
 The third-party assessors will conduct all first-time on-farm assessments as well as second-year
on-farm assessments of those growers found out of compliance in a first- time assessment.
21. Monsanto will annually refine the on-farm assessment program for the MON 89034 x MON 88017 product
to reflect the adoption rate and level of refuge compliance for the product.
22. Monsanto will follow up with growers who have been found significantly out of compliance under the on-
farm assessment program and are found to be back in compliance the following year:
 All growers found to be significantly out of compliance in a prior year will annually be sent
additional refuge assistance information for a minimum of two years by Monsanto, seed
supplier, or third-party assessor, after completing the assessment process;
 Monsanto will conduct follow-up checks on growers found to be significantly out of compliance
within three years after they are found to be back in compliance;
 A grower found with a second incident of significant non-compliance with refuge requirements
for the Bt corn product within a five-year period will be denied access to Monsantos Bt corn
products the next year. Similarly, seed dealers who are not fulfilling their obligations to
inform/educate growers of their IRM obligations will lose their opportunity to sell Bt corn.

e. Insect Resistance Monitoring and Mitigation Plan for MON 89034 x MON 88017
1. EPA is imposing the following conditions for the Cry1A.105 and Cry2Ab2 toxins expressed in
MON 89034 x MON 88017
Monsanto must monitor for resistance to Cry1A.105 and Cry2Ab2 expressed in MON 89034 x MON 88017.
The monitoring program shall consist of two approaches: (1) focused population sampling and laboratory
testing; and (2) investigation of reports of less-than expected control of labeled insects. Should field-relevant
resistance be confirmed, an appropriate resistance management action plan will be implemented.
Focused Population Sampling
Monsanto shall annually sample and bioassay populations of the key target pests: Ostrinia nubilalis
(European corn borer; ECB), Diatraea grandiosella (southwestern corn borer; SWCB), and Helicoverpa zea
(corn earworm; CEW). Sampling for the target pests will be focused in areas identified as those with the
highest risk of resistance development (e.g., where lepidopteran active Bt hybrids are planted on a high
proportion of the corn acres, and where the insect species are regarded as key pests of corn). Bioassay
methods must be appropriate for the goal of detecting field-relevant shifts in population response to MON
89034 x MON 88017 and/or changes in resistance allele frequency in response to the use of MON 89034 x
MON 88017 and, as far as possible, should be consistent across sampling years to enable comparisons with
historical data.
The number of populations to be collected shall reflect the regional importance of the insect species as a pest,
and specific collection regions will be identified for each pest. For ECB, a minimum of twelve (12)
populations across the sampling region will be targeted for collection at each annual sampling. For SWCB,
the target will be a minimum of six (6) populations. For CEW, the target will be a minimum of ten (10)
populations. Pest populations should be collected from multiple corn-growing states reflective of different
geographies and agronomic conditions. To obtain sufficient sensitivity to detect resistance alleles before they
become common enough to cause measurable field damage, each population collection shall attempt to target
400 insect genomes (egg masses, larvae, mated females, and/or mixed-sex adults), but a successful
population collection will contain a minimum of 100 genomes. It is recognized that it may not be possible to
collect the target number of insect populations or genomes due to factors such as natural fluctuations in pest
density, environmental conditions, and area-wide pest suppression.
The sampling program and geographic range of collections may be modified as appropriate based on changes
in pest importance and for the adoption levels of MON 89034 x MON 88017. EPA shall be consulted prior to
the implementation of such modifications.
Monsanto will report to EPA, on or before August 31st of each year, the results of the population sampling
and bioassay monitoring program.
Any incidence of unusually low sensitivity to the Cry1A.105 and/or Cry2Ab2 proteins in bioassays shall be
investigated as soon as possible to understand any field relevance of such a finding. Such investigations shall
proceed in a stepwise manner until the field relevance can be either confirmed or refuted, and results of these
shall be reported to EPA annually on or before August 31st. The investigative steps will include the
Page 11 of 20 
EPA Reg. No. 524576 
OPP Decision No. 544525   
following:
1. Re-test progeny of the collected population to determine whether the unusual bioassay
response is reproducible and heritable. If it is not reproducible and heritable, no further action
is required.
2. If the unusual response is reproducible and heritable, progeny of insects that survive the
diagnostic concentration will be tested using methods that are representative of exposure to
MON 89034 x MON 88017 under field conditions. If progeny do not survive to adulthood,
any suspected resistance is not field relevant and no further action is required.
3. If insects survive steps 1 and 2, resistance is confirmed, and further steps will be taken to
evaluate the resistance. These steps may include the following:
a. Determining the nature of the resistance (i.e., recessive or dominant, and the level of
functional dominance);
b. Estimating the resistance allele frequency in the original population;
c. Determining whether the resistance allele frequency is increasing by analyzing field
collections in subsequent years sampled from the same site where the resistance
allele(s) was originally collected;
d. Determining the geographic distribution of the resistance allele by analyzing field
collections in subsequent years from sites surrounding the site where the resistance
allele(s) was originally collected.
Should field-relevant resistance be confirmed, and the resistance appears to be increasing or spreading,
Monsanto will consult with EPA to develop and implement a case-specific resistance management action
plan.
Investigation of Reports of Unexpected Levels of Damage by the Target Pests
Monsanto will follow up on grower, extension specialist, or consultant reports of unexpected levels of
damage by the lepidopteran pests listed on the pesticide label. Monsanto will instruct its customers to contact
them if such incidents occur. Monsanto will investigate all legitimate reports submitted to the company or the
company's representatives.
If reports of unexpected levels of damage lead to the suspicion of resistance in any of the key target pests
(ECB, SWCB, and CEW), Monsanto will implement the actions described below, based on the following
definitions of suspected resistance and confirmed resistance.
Suspected Resistance
EPA defines suspected resistance to mean field reports of unexpected levels of insect-feeding damage for
which:
 The corn in question has been confirmed to be lepidopteran-active Bt corn;
 The seed used had the proper percentage of corn expressing Bt protein;
 The relevant plant tissues are expressing the expected level of Bt protein; and
Page 12 of 20 
EPA Reg. No. 524576 
OPP Decision No. 544525   
 It has been ruled out that species not susceptible to the protein could be responsible for the damage,
that no climatic or cultural reasons could be responsible for the damage, and
 That there could be no other reasonable causes for the damage.
EPA does not interpret suspected resistance to mean grower reports of possible control failures or suspicious
results from annual insect monitoring assays, nor does EPA intend that extensive field studies and testing be
undertaken to confirm scientifically the presence of insects resistant to MON 89034 x MON 88017 in
commercial production fields before responsive measures are undertaken.
If resistance is suspected, Monsanto will instruct growers to do the following:
 Use alternative control measures in MON 89034 x MON 88017 fields in the affected region to
control the target pest during the immediate growing season.
 Destroy MON 89034 x MON 88017 crop residues in the affected region within one (1) month after
harvest with a technique appropriate for local production practices to minimize the possibility of
resistant insects over- wintering and contributing to the next season's target pest population.
Additionally, if possible, and prior to the application of alternative control measures or destruction of crop
residues, Monsanto will collect samples of the insect population in the affected fields for laboratory rearing
and testing. Such rearing and testing shall be conducted as expeditiously as practical.
Confirmed Resistance
EPA defines confirmed resistance to mean, in the case of field reports of unexpected levels of damage from
the key target pests, that all the following criteria are met:
 There is >30% insect survival and commensurate insect feeding in a bioassay, initiated with
neonate larvae, that uses methods that are representative of exposure to Bt corn hybrids under field
conditions (ECB and SWCB only).
 In standardized laboratory bioassays using diagnostic concentrations of the Bt protein suited to the
target pest in question, the pest exhibits resistance that has a genetic basis and the level of survivorship
indicates that there may be a resistance allele frequency of ≥ 0.1 in the sampled population.
 In standardized laboratory bioassays, the LC
50 exceeds the upper limit of the 95% confidence interval
of the LC50 for susceptible populations surveyed both in the original baselines developed for this pest
species and in previous years of field monitoring.
Response to Confirmed Resistance in a Key Target Pest as the Cause of Unexpected Levels
of Damage in the Field
When field resistance is confirmed (as defined above), the following steps will be taken by Monsanto:
 EPA will receive notification within 30 days of resistance confirmation;
 Affected customers and extension agents will be notified about confirmed resistance within 30 days;
Page 13 of 20 
EPA Reg. No. 524576 
OPP Decision No. 544525   
 Monitoring will be increased in the affected area and local target pest populations will be
sampled annually to determine the extent and impact of resistance;
 If appropriate (depending on the resistant pest species, the extent of resistance, the timing of
resistance, and the nature of resistance, and the availability of suitable alternative control measures),
alternative control measures will be employed to reduce or control target pest populations in the
affected area. Alternative control measures may include advising customers and extension agents in
the affected area to incorporate crop residues into the soil following harvest to minimize the
possibility of over-wintering insects, and/or applications of chemical insecticides;
 Unless otherwise agreed with EPA, stop sale and distribution of the relevant lepidopteran-active Bt
corn hybrids in the affected area immediately until an effective local mitigation plan, approved by
EPA, has been implemented;
 Monsanto will develop a case-specific resistance management action plan within 90 days according
to the characteristics of the resistance event and local agronomic needs. Monsanto will consult with
appropriate stakeholders in the development of the action plan, and the details of such a plan shall be
approved by EPA prior to implementation;
 Monsanto will notify affected parties (e.g., growers, consultants, extension agents, seed
distributors, university cooperators, and state/federal authorities as appropriate) in the region of
the resistance situation and approved action plan; and
 In subsequent growing seasons, maintain sales suspension and alternative resistance management
strategies in the affected region(s) for the Bt corn hybrids that are affected by the resistant
population until an EPA-approved local resistance management plan is in place to mitigate the
resistance.
A report on results of resistance monitoring and investigations of damage reports must be submitted to EPA,
on or before August 31st of each year, for the duration of the registration.
2. EPA is imposing the following conditions for the Cry3Bb1 toxin expressed in MON 89034 x MON
88017:
a) Investigation of Reports of Unexpected Levels of Damage (UXD) by Corn Rootworm (CRW):
Performance Inquiries
(1) Monsanto is required to investigate "performance inquiries" (i.e., reports of unexpected CRW
damage to MON 89034 x MON 88017) from growers. Fields (defined as a tract separated by
permanent boundaries such as fences, permanent waterways, woodlands, croplines not subject
to change because of farming practices, or other similar features) with unexpected damage that
meet both of the criteria below must be subjected to the follow-up actions in part 2) below:
a. The affected plants are confirmed to be MON 89034 x MON 88017 plants (take leaf
samples to determine the presence of the CRW-active Bt protein); and
b. Corn rootworm feeding caused root damage with a Node Injury Score (NIS) > 1.0 on
Page 14 of 20 
EPA Reg. No. 524576 
OPP Decision No. 544525   
at least 50% of plants surveyed in a transect sampling of the damaged site(s) within the
field.
(2) Follow-up actions (performance inquiries). For MON 89034 x MON 88017 fields meeting the
criteria in part 1) above, Monsanto must take the following actions:
a. Collect at least 250 (ideally 500 or more) CRW adult individuals from the damaged
site within the field in question. Collections may be extended to the whole field, if
necessary to obtain sufficient CRW adult individuals. Collected populations must be
subjected to the steps described for "investigation of populations of concern" in section
e(2)(b) below.
o If collections are unsuccessful, visit affected farm or field the following year
(assuming the grower continues to be a customer and repurchases seed and does
not rotate the field to a non-host crop) and attempt to collect CRW adults. If beetles
are not present the subsequent year, see section e(2)(b)(3)(c) below.
b. Review with the grower their CRW management practices and provide CRW
management recommendations including an assessment of corn fields with similar
trait(s) adjacent to the affected corn field that are managed by the same grower.
c. Use of single trait products containing the CRW traits in MON 89034 x MON 88017
in fields with unexpected damage in previous years should be discouraged.
Recommended management options include, but are not limited to, the following:
o Primary option:
• Rotation to non-host crop (e.g., soybean)
o Secondary options:
• Use of pyramided Bt corn products one or more different CRW PIP trait(s)
• Use of different single-CRW PIP traits (i.e., an alternative CRW-active PIP)
• Use of non-Bt or non-CRW protected corn
o Tertiary options:
• If additional pest management need is determined beyond the sec
ondary
options listed above, additional corn rootworm control tools (e.g., soil
insecticides, seed-applied insecticides, chemigation) should be used.
d. If field(s) with UXD is/are planted to a non-host crop (e.g., soybean) the following
year, then the area will be considered “mitigated” (as discussed in section e(2)(b)(3)(d)
below) even if subsequent bioassay results show that the population was resistant. No
further action will be required by Monsanto for the UXD case.
(3) Monsanto must submit an annual report to EPA detailing activities related to investigations of
Page 15 of 20 
EPA Reg. No. 524576 
OPP Decision No. 544525   
unexpected damage (UXD). This report will include the information from the most recent and
previous corn growing seasons:
a. Information from the most recent season:
o The number of UXD reports investigated.
o Location (by county and state).
o CRW sampling (number and location of populations collected).
b. Information from the previous season:
o The final disposition of UXD fields from the previous season (i.e., the management
practices employed in response to UXD if the grower continues to be a customer.
o Results from bioassays conducted on CRW populations from UXD fields where the
primary management option, rotation to non-host crop, was not used.
c. Grower information, such as farm addresses or other personally identifiable information,
or other sensitive business/customer information must not be included in this report. This
report must be submitted by November 30th each year.
b) Investigation of Population of Concern
1. Monsanto must conduct investigations of all CRW populations collected as part of the performance
inquiry process in section e(2)(a) above. These investigations must include the use of an EPA-approved
bioassay to determine if sampled CRW populations are resistant to Cry3Bb1. Acceptable assays must be
able to function as diagnostic tools capable of distinguishing resistant populations from susceptible ones.
Unless previously approved, Monsanto must consult with EPA on their bioassay prior to its use.
2. A CRW population will be considered by EPA to be resistant to a CRW PIP toxin if the following
criteria are met and additional collections and testing are not deemed to be necessary (based on part 3)
below):
a. An initial performance inquiry investigation results in a finding of Unexpected Damage; and
b. Where green tissues are available and if plants are unusually stressed due to agronomic and/or
environmental factors, Bt protein levels in affected plants are found to be within the
documented range for that hybrid (if data are available); and
c. Either (A): On-plant bioassays of insect collections from the UXD fields result in the
following two statistically relevant comparisons
i. A statistically significant difference in measures of either mortality or sublethal effects
(growth/development) between the field population and a relevant susceptible control
population (i.e., one that responds as a typical susceptible field population) on Bt corn
containing the single PIP and/or lack of a statistically significant difference in measures
Page 16 of 20 
EPA Reg. No. 524576 
OPP Decision No. 544525   
of mortality or sublethal effect between the field population and a resistant positive
control population1; and
ii. A lack of a statistically significant difference in the same measures of the field population
raised on Bt corn containing the single PIP and non-Bt corn plants.
Or (B): Sublethal seedling bioassay of insect collections from the UXD fields result in two
statistically relevant comparisons
i. A statistically significant difference in measures of sublethal effects
(growth/development) for populations on Bt corn containing the single PIP (normalized
using non-Bt) seedlings between the field population and a relevant susceptible control
population where available or historical field populations and/or lack of a statistically
significant difference in measures between the field population and a resistant positive
control population
1; and
ii. A lack of a statistically significant difference in the same measures of the field population
raised on Bt corn seedlings containing the single PIP and non-Bt corn seedlings
Or (C): Diet-based bioassays of insect collections from the UXD fields result in two
statistically relevant comparisons
i. A statistically significant difference in measures of lethal or sublethal effects
(growth/development) on diet containing the Bt protein (diagnostic concentration or
concentration-response measures) between the field population and a relevant
susceptible control population where available or historical field populations and/or
lack of a statistically significant difference in measures between field population and a
resistant positive control population
1; and
ii. Either a lack of a statistically significant difference in the same measures of the field
population exposed to diet containing the Bt protein (diagnostic concentration) and diet
not containing the Bt protein and/or lack of a statistically significant difference in
measures between the field population and a resistant positive control population, or
lack of a statistically significant concentration and/or lack of a statistically significant
difference in concentration response between the field and a resistant positive control
population1.
3. Mitigation, as detailed in section e(2)(c) below, is required for any CRW population that meets EPAs
resistance criteria above for any of the CRW traits in MON 89034 x MON 88017, unless the
circumstances described below are applicable.
a. To minimize the potential for incorrectly reaching a conclusion of resistance, another year of
CRW adult collections and additional testing is needed to determine resistance if:
i. The results of the bioassays are inconclusive (e.g., the results of the statistical analysis are
unclear because of low sample sizes) or
                                                             
1 If a resistant positive control population is not available or accessible, Monsanto must consult with EPA prior to initiating bioassays
and work to develop an appropriate resistant positive control population.
Page 17 of 20 
EPA Reg. No. 524576 
OPP Decision No. 544525   
ii. Another reasonable explanation for the unexpected damage exists (e.g., high pest pressure
and/or high plant stress).
b. In these cases, Monsanto and EPA will discuss and align on next steps before reaching any
resistance conclusion.
c. If CRW collections are not possible in the current year or subsequent year due to successful
management practices, then no further investigation is needed. The population would be
considered "mitigated" meaning, in this case, that the population is suppressed or extirpated for
the UXD field. However, EPA recommends that Monsanto continue to be vigilant in areas where
CRW populations were successfully mitigated.
d. If a UXD field receives non-host crop (e.g., soybean) rotation the following year as described in
Section e(2)(a)(2) above, no additional mitigation is subsequently required.
c) Mitigation of CRW Populations Meeting EPAs Resistance Criteria
1. For any CRW population found to be resistant to the Cry3Bb1 trait in MON 89034 x MON 88017 under
EPAs criteria described in section e(2)(b) above, Monsanto must take the following steps:
a) Monsanto must inform EPA of all the results of the bioassays as soon as possible, but at least
within 30 days if measures are triggered.
b) The mitigation action area (MAA) is defined as the growers farming operation up to a ½ mile
radius from the damaged site that produced the resistant population.
c) Within 30 days of informing EPA of the results of the bioassays, Monsanto must notify state
extension agents and crop consultants who operate within the county in which resistance was
identified. Information shared must include identification of the county in which resistance was
detected and trait(s) affected.
d) Within the MAA, Monsanto must do the following:
i. Prior to finalizing the growers seed order for the following season, inform the affected
grower and other registrants that hold registrations containing the compromised trait(s).
Monsanto must also inform neighboring growers if those growers are customers of
Monsanto. Information shared must include identification of the county in which
resistance was detected and trait(s) affected;
ii. Discontinue sales/planting of products containing the compromised trait(s) without
additional/alternative (i.e. non-compromised) CRW traits until resistance has been
demonstrated to have been mitigated. Other Bt registrants selling such products in the
MAA are encouraged, but cannot be required, to follow suit;
iii. Monsanto must monitor the resistant population in the MAA, as long as grower remains a
customer of the company, until mitigation has been demonstrated as described in part e
below unless otherwise agreed with EPA.
iv. Require any pyramids sold by Monsanto containing the compromised trait(s) be planted
with a 20% refuge until resistance has been demonstrated to have been mitigated. Other
Page 18 of 20 
EPA Reg. No. 524576 
OPP Decision No. 544525   
Bt corn registrants selling such pyramided products in the MAA are encouraged, but
cannot be required by this term of registration, to follow suit;
v. For Monsantos affected customers field(s), the mitigation goal is to control the resistant
CRW population. Within the MAA Monsanto shall encourage the use of “Mitigation
Practices” including:
1. Primary option: Rotation to a non-host crop (e.g., soybean);
2. Secondary options:
a. Use of pyramided Bt corn products with different CRW PIP traits;
b. Use of different single-CRW PIP traits (i.e., an alternative CRW-active PIP);
c. Use of non-Bt corn or non-CRW protected corn (with/without soil-applied
insecticide);
3. Tertiary options:
a. If additional pest management need is determined beyond the secondary
options listed above, additional CRW control tools (e.g., soil insecticides,
seed-applied insecticides, chemigation) should be used.
b. Use of foliar applications to control adults (when appropriate economic
thresholds have been met) may be used in conjunction with one or more of
the above;
e) A resistant CRW population in the MAA will be considered mitigated if one of the following
criteria is met:
i. Corn fields within the MAA are rotated to a non-host crop (e.g. soybean) for one
growing season.
ii. After implementation of mitigation practices (part d.v above), resistance
monitoring (sampling) is conducted but few CRW are found (i.e., <0.1 adults per
plant) and environmental conditions (e.g., weather) are unlikely to be responsible
for the lack of adult CRW presence. If environmental conditions are a factor, then
monitoring should continue for another season.
iii. After implementation practices (part d.v above), resistance monitoring (sampling)
is conducted, CRW are found and collected, and bioassays (section e(2)(b)(2)
above) show that the population susceptibility to the compromis
ed trait(s) has
returned to baseline levels.
f) The mitigation actions in part d above can be lifted, and growers can resume the use of MON
89034 x MON 88017 as a primary tool for CRW management in the MAA, only when Monsanto
demonstrates that successful mitigation as described in part e above has been achieved.
2. Based on further research to understand CRW resistance to Bt PIPs, EPA will consider refinements to
the resistance mitigation program. Such research may include characterizing the genetics of resistance
Page 19 of 20 
EPA Reg. No. 524576 
OPP Decision No. 544525   
(e.g., number of genes, functional dominance, mechanism of resistance, and cross-resistance) and the
biology of resistant insects (e.g., fitness in the presence and absence of the product), and other control
tactics.
f. Annual Reporting Requirements for MON 89034 x MON 88017
The following annual reports must be submitted:
1. Compliance Assurance Plan: Compliance Assurance Program activities, including IRM Grower Survey
results and on-farm assessment results for the prior year and plans for the compliance assurance program
for the current year, on or before January 31st each year.
2. Insect Resistance Monitoring Results (Cry1A.105 and Cry2Ab2 only): results of monitoring and
investigations of damage reports, August 31st of each year.
3. IPM Stewardship Program (Cry3Bb1 only): Activities conducted under the IPM stewardship program,
including an anonymous survey of grower practices, adoption levels of the various crop rotation options
(if employed) and other elements of the stewardship program, on or before January 31st of each year.
4. Unexpected Damage Investigations (Cry3Bb1 only): Activities related to investigations of unexpected
damage (UXD), including number and location of UXD cases, insect sampling, bioassays, and final
disposition of UXD fields from the most recent and previous corn growing seasons, on or before
November 30th of each year.

DIRECTIONS FOR USE
It is a violation of Federal law to use this product in any man ner inconsistent with this labeling. This
product must be used as specified in the terms and conditions of the registration.
MON 89034 × MON 88017 protects corn crops from leaf, stalk, and ear damage caused by corn borers
and root damage caused by corn rootworm larvae.
This plant-incorporated protectant (PIP) may be combined throug h conventional breeding with other
registered PIPs that are similarly approved for use in combinat ion, through conventional breeding, with
other registered PIPs to produce inbred corn lines and hybrid c orn varieties with combined pesticidal
traits.
1) Refuge Requirements for MON 89034 × MON 88017 Field Corn
In order to minimize the risk of corn borers and corn rootworms developing resistance to MON 89034 ×
MON 88017 corn, an insect resistance management (IRM) plan must be implemented which includes
planting of a structured refuge.
These refuge requirements do not apply to seed increase/propagation of inbred and hybrid seed corn up to
a total of 20,000 acres per county and up to a combined United States (U.S.) total of 250,000 acres per
PIP active ingredient per registrant per year. Furthermore, th ese refuge requirements do not apply to
commercial hybrid sweet corn.
The refuge and MON 89034 × MON 88017 corn should be sown on the same day, or with the shortest
window possible between planting dates to ensure that corn root development is similar among varieties.
If the refuge is planted on rotated ground, then the MON 89034 × MON 88017 corn must also be planted
on rotated ground. If the combined refuge is planted on contin uous corn, then MON 89034 ×
MON 88017 may be planted on either continuous or rotated land ( option encouraged where WCRW
rotation resistant biotype may be present). Refuge options are based on the planting of MON 89034 ×
MON 88017 in cotton or non-cotton growing regions and the insect pressure present in those locations. If
insecticides are applied to the refuge for control of CRW adult s, the same treatment must also be applied
in the same timeframe to MON 89034 × MON 88017.
a) Corn-Belt/Non-Cotton Growing Area Refuge Requirements
For MON 89034 × MON 88017 field corn grown outside cotton-growi ng areas (e.g., the Corn Belt), two
options for deployment of the refuge are available to growers.
The first option is planting a common refuge for both corn borers and corn rootworms. The common
refuge must be planted with corn hybrids that do not contain Bt technologies for the control of corn borers
or corn rootworms. The refuge area must repres ent at least 20% of the growers corn acres ( i.e., sum of
MON 89034 × MON 88017 acres and refuge acres; refuge area must contain 20 acres of corn for every 80
acres of MON 89034 × MON 88017 corn planted). It must be plant ed as block within or adjacent ( e.g.,
across the road) to the MON 89034 × MON 88017 field, perimeter strips (i.e., strips around the field), or
in-field strips. If perimeter or in-field strips are implement ed, the strips must be at least four (4)
consecutive rows wide. The common refuge can be treated with a soil-applied or seed-applied insecticide
to control rootworm larvae and other soil pests. The refuge ca n also be treated with a non-Bt foliar
insecticide for the control of late season pests if pest pressu re reaches an economic threshold for damage;
however, if rootworm adults are present at the time of foliar a pplications then the MON 89034 ×
MON 88017 field (acres) must be treated in a similar manner. E conomic thresholds will be determined
using methods recommended by local or regional professionals ( e.g., Extension Service agents, crop
consultants, etc.
The second option is planting separate refuge areas ( e.g., two refuge areas, a double refuge, or paired
refuge areas) for corn borers and corn rootworms. Refuge plant ing options include: separate fields,
blocks within fields ( e.g., along the edges or headlands), perimeter strips, or in-field strips. If perimeter
or in-field strips are implemented, the strips must be at least 4 consecutive rows wide. The corn borer
refuge must be planted with corn that is not a lepidopteran-protected Bt hybrid, must represent at least 5%
of the growers corn acres, and must be planted within ½ mile of the MON 89034 × MON 88017 field.
The corn borer refuge can be treated with a soil-applied or see d-applied insecticide for corn rootworm
larval control, or a non-Bt foliar applied insecticide for corn borer control if pest pressure reaches an
economic threshold for damage. Economic thresholds will be det ermined using methods recommended
by local or regional professionals (e.g., Extension Service agents, crop consultants, etc.).
The corn rootworm refuge must be planted with corn that is not a corn rootworm-protected Bt hybrid, but
can be planted with Bt hybrids that control corn borers. The corn rootworm refuge must represent at least
20% of the growers corn acres ( i.e., corn rootworm refuge must contain 20 acres of corn for every 80
acres of MON 89034 × MON 88017 corn planted) and must be plante d as a block within or adjacent to
the MON 89034 × MON 88017 field, strips around the field, perim eter strips, or in-field strips. If
perimeter or in-field strips are implemented, the strips must b e at least four (4) consecutive rows wide.
The corn rootworm refuge can be treated with a soil-applied or seed-applied insecticide to control
rootworm larvae and other soil p ests. The refuge can also be t reated with a non-Bt foliar insecticide for
control of late season pests; however, if corn rootworm adults are present at the time of foliar applications
then the MON 89034 × MON 88017 field must be treated in a similar manner.
b) Cotton-Growing Area Refuge Requirements
Cotton-growing areas include the following states: Alabama, Ark ansas, Georgia, Florida, Louisiana,
North Carolina, Mississippi, South Carolina, Oklahoma (only the counties of Beckham, Caddo,
Comanche, Custer, Greer, Harmon, Jackson, Kay, Kiowa, Tillman, Washita), Tennessee (only the
counties of Carroll, Chester, Crockett, Dyer, Fayette, Franklin , Gibson, Hardeman, Hardin, Haywood,
Lake, Lauderdale, Lincoln, Madison, ' Obion, Rutherford, Shelby, and Tipton), Texas (except the counties
of Carson, Dallam, Hansford, Hartley, Hutchinson, Lipscomb, Moo re, Ochiltree, Roberts, and Sherman),
Virginia (only the counties of Dinwiddie, Franklin City, Greens ville, Isle of Wight, Northampton,
Southampton, Suffolk City, Surrey, Sussex), and Missouri (only the counties of Dunklin, New Madrid,
Pemiscot, Scott, Stoddard).
For MON 89034 × MON 88017 field corn grown in cotton growing ar eas of the U.S. the common refuge
and separate refuge options ( e.g., two-refuge options, double-refuge options, paired-refuge opti ons) are
available as specified below.
The first option is planting a common refuge for both corn borers and corn rootworms. The common
refuge must be planted with corn hybrids that do not contain Bt technologies for the control of corn borers
or corn rootworms. The refuge area must repr esent at least 20% of th e growers corn acres ( i.e., sum of
MON 89034 × MON 88017 acres and refuge acres; refuge area must contain 20 acres of corn for every 80
acres of MON 89034 × MON 88017 corn planted). It must be plant ed as block within or adjacent ( e.g.,
across the road) to the MON 89034 × MON 88017 field, perimeter strips (i.e., strips around the field), or
in-field strips. If perimeter or in-field strips are implement ed, the strips must be at least four (4)
consecutive rows wide. The common refuge can be treated with a soil-applied or seed-applied insecticide
to control rootworm larvae and other soil pests. The refuge ca n also be treated with a non-Bt foliar
insecticide for the control of late season pests if pest pressu re reaches an economic threshold for damage;
however, if rootworm adults are present at the time of foliar a pplications then the MON 89034 ×
MON 88017 field (acres) must be treated in a similar manner. E conomic thresholds will be determined
using methods recommended by local or regional professionals ( e.g., Extension Service agents, crop
consultants, etc.).
The second option is planting separate refuge areas ( e.g., two refuge areas, a double refuge, or paired
refuge areas) for corn borers and corn rootworms. Refuge plant ing options include: separate fields,
blocks within fields ( e.g., along the edges or headlands), perimeter strips, or in-field strips. If perimeter
or in-field strips are implemented, the strips must be at least 4 consecutive rows wide. The corn borer
refuge must be planted with corn that is not a lepidopteran-pro tected Bt hybrid, must represent at least
20% of the growers corn acres, and must be planted within ½ mile of the MON 89034 × MON 88017
field. The corn borer refuge can be treated with a soil-applie d or seed-applied insecticide for corn
rootworm larval control, or a non-Bt foliar applied insecticide for corn borer control if pest pressure
reaches an economic threshold for damage. Economic thresholds will be determined using methods
recommended by local or regional professionals (e.g., Extension Service agents, crop consultants, etc.).
The corn rootworm refuge must be planted with corn that is not a corn rootworm-protected Bt hybrid, but
can be planted with Bt hybrids that control corn borers. The corn rootworm refuge must represent at least
20% of the growers corn acres ( i.e., corn rootworm refuge must contain 20 acres of corn for every 80
acres of MON 89034 × MON 88017 corn planted) and must be plante d as a block within or adjacent to
the MON 89034 × MON 88017 field, perimeter strips, or in-field strips. If perimeter or in-field strips are
implemented, the strips must be at least four (4) consecutive r ows wide. The corn rootworm refuge can
be treated with a soil-applied or seed-applied insecticide to c ontrol rootworm larvae and other soil pests.
The refuge can also be treated with a non-Bt foliar insecticide for control of late season pests; however, if
corn rootworm adults are present at the time of foliar applicat ions then the MON 89034 × MON 88017
field must be treated in a similar manner.
