Dear Ms. Clark:
The amended labels referred to above, submitted in connection with registration under the Federal
Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended, are acceptable. Accordingly, EPA
has approved the requested registration amendments, provided Syngenta Crop Protection, LLC
(“Syngenta”) complies with all terms and conditions listed below.
Terms and Conditions
Syngenta must comply with all the following terms and conditions. Release for shipment of these
products constitutes acceptance of the below conditions. If these conditions are not complied with, the
registrations will be subject to cancellation in accordance with FIFRA section 6.
Endangered Species Protection and Formal Consultation
1. For this action, EPA conducted effects determinations under the Endangered Species Act
(ESA). In its final effects determinations (included in a biological evaluation), EPA made may
affect, likely to adversely affect (LAA), determinations for certain listed species and designated
critical habitats for products containing cyantraniliprole (including this product). For these
LAA determinations, EPA also assessed the potential likelihood of jeopardy or adverse
modification in its effects determination, consistent with 50 C.F.R. § 402.40(b)(1). EPA
predicted no potential likelihood of jeopardy for listed species or adverse modification for
designated critical habitat. On September 25, 2023, EPA initiated formal consultation with the
Page 2 of 5
EPA Reg. Nos.
Decision Nos. 593337, 593338, 593342, 593343, 593341, 593344, 594352, 593336, 593339 and
593334
Services. The Services will make the final determination as to the potential for jeopardy for
listed species or adverse modification for designated critical habitat in any final biological
opinions issued at the completion of consultation.
If, following formal consultation with Service(s), additional modifications are identified in any
applicable Biological Opinion, EPA will notify Syngenta in writing within 45 calendar days of
the issuance of the Biological Opinion of any necessary changes. Within 30 calendar days of
receiving EPAs notice, Syngenta must submit an amendment application incorporating the
necessary changes, including amended labels. Alternatively, Syngenta may respond by
submitting a request for voluntary cancellation of this product. If Syngenta fails to comply with
this term, Syngenta has agreed in prior written acceptance of these terms that EPA may cancel
the registration under an expedited process under FIFRA 6(e).
Implementation of Revised Labeling
2. To ensure the prompt adoption of the mitigations in this registration amendment in newly
produced product and previously produced product that is still under Syngentas control,
Syngenta must submit state registrations for approval, in all states where products are currently
registered, for the products with the labeling associated with this approval letter no later than
November 30, 2023.
3. In accordance with 40 C.F.R. § 152.130(c), product may be distributed or sold by Syngenta
under the previously approved labeling for no longer than 12 months from the date of this letter
or 75 days after the final state approval from those submitted under Term #2, whichever is
earlier.
4. Nothing in Terms #2-3 should be read to obligate Syngenta to provide additional labeling for
product that bears the previously approved label but is not under Syngentas control as of the
date of this letter. However, Syngenta should conduct outreach for users of this product to
update them on the forthcoming changes to the label and their importance in mitigating
potential effects to listed species and avoiding violations of the Endangered Species Act.
EPAs Rationale for Approving This Registration Amendment
FIFRA section 3(c)(5) requires EPA to unconditionally approve a registration amendment if:
 “its composition is such as to warrant the proposed claims for it”;
1
 “its labeling and other material required to be submitted comply with the requirements of
[FIFRA]”;2
1 FIFRA § 3(c)(5)(A), 7 U.S.C. § 136a(c)(5)(A). Here, EPA reviewed the proposed labeling and determined that the claims
made for the product were consistent with composition of the product based on the data submitted.
2 FIFRA § 3(c)(5)(B), 7 U.S.C. § 136a(c)(5)(B). Here, EPA reviewed the submitted labeling and other materials submitted
and found them to be compliant with the requirements of FIFRA. Additionally, there are no data gaps.

593334
 “it will perform its intended function without unreasonable adverse effects on the
environment”;
3 and
 “when used in accordance with widespread and commonly recognized practice it will not
generally cause unreasonable adverse effects on the environment.”4
Prior to approving the previous registrations and registration amendments for this product and others
containing cyantraniliprole, EPA considered risks and benefits of approving the registrations and
registration amendments. To determine the risks and benefits, the Agency reviews a large body of
information to determine the effects of using these products. In assessing the risks from use of products
containing cyantraniliprole, EPA has conducted both human health risk assessments
5 and ecological
and environment fate risk assessments.6 EPA also updated its ecological and environmental fate risk
assessments in support of the 2023 draft biological evaluation (BE).7 EPA believes that that these risk
assessments (and the benefits discussed below) are also applicable to the action to approve this
amended registration.

593334
In the human health risk assessments, EPA did not select an acute dietary toxicity endpoint because the
Agency did not identify any effect attributed to a single dose (i.e., CTP is not expected to pose an acute
risk to humans). In general, CTP produces both adverse and adaptive changes in the liver, thyroid
gland, and adrenal cortex. With repeat dosing, consistent findings of mild to moderate increases in
liver weights are observed across multiple species (rats, mice, dogs). CTP was classified as “not likely
to be carcinogenic to humans” based upon data demonstrating lack of treatment-related increase in
tumor incidence in rats and mice. No cumulative effects were identified. CTP presents no
mutagenicity, neurotoxicity, immunotoxicity, developmental reproductive toxicity.
In the environmental risk assessments, EPA identified risks of concern for both aquatic and terrestrial
invertebrates. Overall, however, the major risks of concerns are for direct effects to freshwater,
estuarine/marine, and benthic invertebrates. EPA did not identify direct risks of concerns for birds,
reptiles, amphibians, freshwater fish, terrestrial plants, or aquatic plants.
EPA also considered the benefits of products containing cyantraniliprole, including CTPs activity on a
wide variety of target insects on a variety of crops. CTP is effective for controlling aphids, weevils and
thrips—all major agricultural pests. CTP is not expected to pose any acute risk to humans and was
registered in 2013 as a reduced risk pesticide due to it posing lower relative risk to alternative
chemicals available at that time. CTP also poses lower risk to non-target organisms relative to
alternatives and is compatible with IPM practices.
This amended registration includes additional mitigation measures to address effects to listed species,
including the following:
• Requirement that applicators use coarse/coarser droplets for ground and aerial applications to
reduce spray drift
• Requirement that aerial applications abide by wind-directional buffers, as identified in Bulletins
Live Two (BLT), also to reduce spray drift
• Increase in distance of vegetative filter strips from 25 to 30 feet to mitigate the potential for
runoff to aquatic habitats
• Use of a 25 buffer for airblast applications to dormant, non-bearing and/or vegetation that is
not yet fully leafed out
• Requirement that treated seeds be immediately covered or collected if spilled during loading
After consideration, EPA has determined that approving this amended registration will not cause
unreasonable adverse effects because the amended registrations are not expected to result in increased
exposures
8 and because EPA continues to believe that—consistent with the 2014 registration decision 9
8 While the mitigations in the amended registrations are intended to reduce exposures to listed species, EPA expects that the
mitigations will (1) not increase exposures to other non-listed non-target organisms, and (2) will generally reduce exposures
to all non-target organisms (both listed and non-listed).

and other previous registration decision for products contain cyantraniliprole—the benefits of the se
registrations outweigh any remaining risks of concern from its use and there are no human dietary risks
from uses of cyantraniliprole that are inconsistent with the FFDCA safety standard.
10 Accordingly,
EPA is approving these registration amendments because the FIFRA registration standard is met.
Conclusion
A stamped copy of your labeling is enclosed for your records. This labeling supersedes all previously
accepted labeling. You must submit one copy of the final printed labeling before you release the
product for shipment with the new labeling. Consistent with Terms 2-5 above, and not withstanding 40
C.F.R. § 152.130(c), you may only distribute or sell
11 this product under either the final stamped label
associated with this approval letter or with accompanying labeling that incorporates the mitigations in
this registration amendment.
Should you wish to add/retain a reference to the companys website on your label, then please be
aware that the website becomes labeling under FIFRA and is subject to review by the Agency. If the
website is false or misleading, the product would be misbranded and unlawful to sell or distribute
under FIFRA section 12(a)(1)(E). 40 C.F.R. § 156.10(a)(5) lists examples of statements EPA may
consider false or misleading. In addition, regardless of whether a website is referenced on your
products label, claims made on the website may not substantially differ from those claims approved
through the registration process. Therefore, should the Agency find or if it is brought to our attention
that a website contains false or misleading statements or claims substantially differing from the EPA-
approved registration, the product will be referred to EPAs Office of Enforcement and Compliance.

Environmental Hazards
This pesticide is toxic to aquatic invertebrates. Drift and runoff may be hazardous to
aquatic organisms in water adjacent to treated areas.
This product is highly toxic to bees exposed to direct treatment or residues on blooming
crops or weeds. Do not apply this product or allow it to drift to blooming crops or weeds
if bees are foraging the treatment area.
Surface Water Advisory
This product may impact surface water quality due to runoff of rainwater. This is
especially true for poorly draining soils and soils with shallow ground water. This
product is classified as having a high potential for reaching surface water via runoff for
several months or more after application.
Do not apply within 50 feet of aquatic habitats (such as, but not limited to, lakes,
reservoirs, rivers, permanent streams, wetlands or natural ponds, estuaries, and
commercial fish farm ponds).
Do not cultivate within 30 feet of the aquatic area to allow growth of a vegetative
filter strip.
Runoff of this product will be reduced by avoiding applications when rainfall is
forecasted to occur within 48 hours.
Ground Water Advisory
This chemical may leach into ground water if used in areas where soils are permeable,
particularly where the water table is shallow.
Spray Drift Advisory
Mainspring GNL may be applied by ground equipment or aerial application.
Ground Application
For broadcast applications made at planting or prior to the emergence of crops,
applicators are required to use a coarse or coarser droplet size (ASABE S572.1). For all
other broadcast applications, applicators are required to use a medium or coarser
droplet size (ASABE S572.1).
Aerial Application
Mainspring GNL
100-1543
5
Avoid spraying at a height greater than 10 ft above the ground or vegetative canopy
unless a greater application height is necessary for pilot safety.
If the windspeed is 10 miles per hour or less, applicators must use ¾ swath
displacement upwind at the downwind edge of the field. When the windspeed is
between 11-15 miles per hour, applicators must use a full swath displacement upwind at
the downwind edge of the field.
DO NOTapply when wind speeds exceed 15 mph at the application site. If the
windspeed is greater than 10 mph, the boom length must be 65% or less of the
wingspan for fixed wing aircraft and 75% or less of the rotor diameter for helicopters.
Otherwise, the boom length must be 75% or less of the wingspan for fixed-wing aircraft
and 90% or less of the rotor diameter for helicopters.
DO NOTapply during temperature inversions.
For fixed wing and helicopter aerial applications made at planting or prior to the
emergence of crops, applicators are required to use a coarse or coarser droplet size
(ASABE S572.1). For all other fixed wing and helicopter aerial applications, applicators
are required to use a medium or coarser droplet size (ASABE S572.1)

SURFACE WATER PROTECTION STATEMENT
For foliar uses: DO NOTapply during rain.
PRODUCT INFORMATION
Mainspring GNL is an insecticide that controls listed insect pests on ornamental plants;
ornamental bulb, corm and tuber crops; conifers; Christmas trees; [vegetable plants]
and non-bearing fruit and nut trees grown in greenhouses and nurseries (including field-
and container-grown plants grown outdoors and in shade houses, lath houses and other
ornamental production structures), conifer nurseries, retail nurseries, residential and
commercial landscapes, and interior plantscapes.
Mainspring GNL may be applied to plants and grassy areas that are grown for aesthetic
recreational or other property maintenance purposes or climatic modification in or
around home lawns, residential dwellings, business and office complexes, shopping
complexes, multi-family residential complexes, institutional buildings, airports,
cemeteries, interior plantscapes, ornamental gardens, wildlife plantings, parks,
playgrounds, schools, daycare facilities, other landscaped areas. Mainspring GNL may
also be applied to plants in and around small and large companion-animal (including
horses) boarding and exercising areas providing the animals exposed to the treated
areas are not used for human consumption.
Mainspring GNL
100-1543
12
Mainspring GNL can be applied as a foliar spray, a soil broadcast spray, a soil drench,
and soil injection and by chemigation. When applied as a foliar spray, the product will
have translaminar and systemic movement, providing residual efficacy of foliar insect
pests. When Mainspring GNL is applied by drench to the root system of plants, it will be
translocated upward in the plant due to its systemic activity. Systemic upward
movement in herbaceous plants will be quicker than in those of woody plants, such as
trees and shrubs. Soil applications should be made prior to anticipated pest infestation
to allow adequate systemic movement to achieve optimum levels of control.
Mainspring GNL controls a broad range of chewing and sucking pests. Insecticidal
activity is primarily through ingestion. This results in paralysis, rapid inhibition of feeding
and disruption of other key physiological functions. Depending on the target pest,
mortality occurs within two to seven days. The rapid cessation of feeding results in less
plant injury. It is recommended that Mainspring GNL be applied when pest populations
are low to prevent targeted insects from increasing to damaging levels.
Integrated Pest Management (IPM) Programs
Mainspring GNL can be used in an IPM program with biological agents for controlling
ornamental pest. Beneficial arthropods can help control other insect and mite pests and
reduce the potential for secondary pest outbreaks. Mainspring GNL can reduce the
target pest species that serve as a food source for beneficial arthropods, which can
indirectly affect their populations. If Mainspring GNL is tank-mixed with a product that
negatively impacts beneficial arthropods, the full benefit of Mainspring GNL to an IPM
program may not be realized.
Resistance Management
GROUP 28 INSECTICIDE
Mainspring GNL is in GROUP 28 of the EPA's Insecticide and Acaricide Groups based
on Target Site of Action.
Some insects are known to develop resistance to products that have been used
repeatedly for control. When this occurs, the label use rates can fail to reduce the pest
population below threshold levels. As the development of resistance cannot be
predicted, the use of this product should conform to resistance management strategies
established for the use area. These strategies may include incorporation of cultural and
biological control practices, alternation of active classes of insecticides on succeeding
generations and targeting the most susceptible life stage. Consult your local
Cooperative Extension Service specialist or pest control advisor for the latest
information on resistance management in your area or crop.
Plant Safety
Mainspring GNL
100-1543
13
Mainspring GNL has been found to be generally safe when applied according to label
use directions to the listed plants. Phytotoxicity testing has not been performed on all
possible species and cultivars. Individual plant species or cultivars may be sensitive to
the final spray solution, including tank mixes. If local experience is not available, a
small number of plants should be treated and observed for phytotoxicity for at least one
week before making an application to the entire planting to ensure plant safety.
APPLICATION EQUIPMENT CLEANING
Prior to application, start with clean, well maintained application equipment.
Immediately following application, thoroughly clean all application equipment to reduce
the risk of forming hardened deposits that might become difficult to remove. Drain
application equipment. Thoroughly rinse application equipment and flush hoses, boom
and nozzles with clean water. Clean all other associated application equipment. Take
all necessary safety precautions when cleaning equipment. DO NOT clean equipment
near wells, water sources or desirable vegetation. Dispose of waste rinse water in
accordance with local regulations.
CALIBRATION OF APPLICATION EQUIPMENT
Proper maintenance and calibration of spraying and chemigation equipment are
essential for optimal insect pest control. If you have questions about calibration, contact
a State Extension Service specialist, the equipment manufacturer or other experts.
A person knowledgeable of the chemigation system and responsible for its operation, or
under the supervision of the responsible person, shall shut the system down and make
necessary adjustments if the need arises.
MIXING INSTRUCTIONS
Mainspring GNL is a suspension concentrate (SC) formulation. Mainspring GNL must
be diluted with water before application.
Mainspring GNL readily mixes with water and may be used in many different types of
application equipment and applied to either the foliage or root system. Mix product with
the required amount of water and apply according to label use directions.
The pH of application mixtures containing Mainspring GNL should be adjusted to a pH
of 8 or less using a commercially available acidifier. When applying Mainspring GNL by
chemigation, adjust the pH of the chemigation systems supply or nurse tank using a
commercially available acidifier. Adjust the pH of application mixtures after all products
being applied have been added to the tank and uniformly mixed for broadcast and
drench applications.
Mixing Directions
1. Use clean, well maintained and properly calibrated application equipment.
2. Fill sprayer tank 1/4 to 1/2 full of water.
Mainspring GNL
100-1543

3. Shake the container of Mainspring GNL well before pouring.
4. Add the appropriate amount of Mainspring GNL directly into the spray tank.
5. If preparing a tank mixture, follow the tank-mixing sequence below.
6. Mix the spray solution thoroughly and continue agitation to keep the insecticide in
suspension. Use mechanical or hydraulic agitation. Do not use air agitation.
7. It is recommended that the mixture not be stored in the spray or mix tank overnight.
Tank mixtures
Mainspring GNL may be tank-mixed with other pesticides. When tank-mixing
Mainspring GNL with other pesticides, observe the restrictions and precautions on all
product labels.
DO NOT exceed the label application rates for any product.
DO NOT mix Mainspring GNL with any product containing a label prohibition against
such mixing.
Always follow the tank mix instructions of the product label that is most restrictive.
The physical compatibility of Mainspring GNL may vary with different sources of
pesticide products and local cultural practices. A jar compatibility test is recommended
prior to tank-mixing with other pesticides, fertilizers or adjuvants to ensure the
compatibility of Mainspring GNL with the other products. For a jar compatibility test, mix
the proper proportions of any pesticides, adjuvants, or fertilizers in water in a pint or
quart jar and allow it to stand at least 20 minutes. If the combination remains mixed or
can be re-mixed readily, the mixture is considered physically compatible.
Tank-mixing Sequence

APPLICATION PROCEDURES
Mainspring GNL may be used in many different types of application equipment and
applied to either the foliage or root system. Mix product with the required amount of
water and apply as desired dependent upon the selected use pattern.
Consult your Cooperative Extension Service specialist or pest control advisor for
regionally specific information regarding application timing.
MANDATORY SPRAY DRIFT REDUCTION MANAGEMENT
Do not apply when wind speed favors drift beyond the area intended for treatment. The
interaction of many equipment- and weather-related factors determines the potential for
spray drift. The applicator is responsible for considering all of these factors when
making application decisions. Avoiding spray drift is the responsibility of the applicator.
Importance of Droplet Size: An important factor influencing drift is droplet size.
Select nozzles and pressure that deliver medium spray droplets as indicated in nozzle
manufacturers catalogs and in accordance with ASAE Standard S-572. Nozzles that
deliver coarse spray droplets may be used to reduce spray drift provided spray volume
per acre (GPA) is increased to maintain crop coverage. For aerial application, spray
should be released at the lowest possible height consistent with good pest control. For
aerial applications, do not release spray at a height greater than 10 ft above the ground
or vegetative canopy, unless a greater application height is necessary for pilot safety.
Low humidity and high temperature increase the evaporation rate of spray droplets and
therefore the likelihood of spray drift to aquatic areas. Avoid spraying during conditions
of low humidity and/or high temperature.
Wind Speed Restrictions:
For Aerial Applications:
If the windspeed is 10 miles per hour or less, applicators must use ¾ swath
displacement upwind at the downwind edge of the field. When the windspeed is
between 11-15 miles per hour, applicators must use a full swath displacement upwind at
the downwind edge of the field.
Do not apply when wind speeds exceed 15 mph at the application site. If the windspeed
is greater than 10 mph, the boom length must be 65% or less of the wingspan for fixed
wing aircraft and 75% or less of the rotor diameter for helicopters. Otherwise, the boom
length must be 75% or less of the wingspan for fixed-wing aircraft and 90% or less of
the rotor diameter for helicopters.
For broadcast applications made at planting or prior to the emergence of crops:
applicators are required to use a coarse or coarser droplet size (ASABE S572.1). For all
other broadcast applications, applicators are required to use a medium or coarser
droplet size (ASABE S572.1
Mainspring GNL
100-1543
16
Restrictions during Temperature Inversions: Do not make aerial or ground
applications during temperature inversions. Drift potential is high during temperature
inversions. Temperature inversions restrict vertical air mixing, which causes small
suspended droplets to remain close to the ground and move laterally in a concentrated
cloud. Temperature inversions are characterized by increasing temperature with
altitude and are common on nights with limited cloud cover and light to no wind. They
begin to form as the sun sets and often continue into the morning. Their presence can
be indicated by ground fog. However, if fog is not present, the movement of smoke
from a ground source can also identify inversions. Smoke that layers and moves
laterally in a concentrated cloud (under low wind conditions) indicates an inversion,
while smoke that moves upward and rapidly dissipates indicates good vertical air
mixing.
FOLIAR APPLICATION
Foliar application rates are listed in Table 1. Foliar applications offer locally systemic
activity with residual control of listed pests. Mix the Mainspring GNL with the required
amount of water and apply as a full coverage foliar spray to control the target pest.
Apply Mainspring GNL when pest populations are low to prevent them from increasing
to damaging levels
When making foliar applications to plants with hard-to-wet foliage, such as holly, ivy, or
pine, the addition of a spreading adjuvant is recommended. Do not use adjuvants with
binding or sticking properties as these may reduce absorption of Mainspring GNL by the
plant. Use sufficient water volume to provide thorough and uniform coverage. Avoid
making applications where uniform coverage cannot be obtained or where excessive
spray drift can occur.
If making a low volume, or mist-type application, use the equivalent amount of product
as you would when making an application with higher volumes of water for a given area.

BROADCAST APPLICATION
Broadcast applications of Mainspring GNL may be applied for white grub, annual
bluegrass weevils, billbugs, chinch bugs (suppression), turf caterpillars, European crane
flies, and spittlebugs in grassy, weedy, or bare soil areas, including residential and
commercial landscapes. Broadcast application rates for these areas are presented in
Table 2. Apply in sufficient water to uniformly cover the area being treated (a minimum
of 2 gallons per 1,000 square feet is recommended). Irrigate immediately after
application or allow rainfall to move the product into the soil. Use properly calibrated
application equipment that will produce a uniform, coarse droplet spray, using a low
pressure setting to eliminate off target drift. Mainspring GNL may be applied either
before planting or after plants have been established.
APPLICATION TIMING
White Grubs: Apply Mainspring GNL from [April][May][June] to [early] September for
preventative and early curative control of listed white grub species. The need for an
application may be based on historical monitoring of the site, previous records or
experiences, current season adult trapping or other methods. Irrigate turf immediately
after application or allow rainfall to move the product into the soil.
Annual Bluegrass Weevil: Apply Mainspring GNL when overwintered adult annual
bluegrass weevils are observed in late April or early May to prevent damage from first
generation larvae in late-May and June. An application of Mainspring GNL at this time
will also provide white grub control.
Mainspring GNL
100-1543
18
Billbugs:Apply Mainspring GNL when overwintered adult billbugs are first observed.
This will usually occur in late April or early May in regions with cool-season turfgrasses.
An application of Mainspring GNL at this time will also provide white grub control.
Chinch Bugs: For suppression of chinch bugs, apply Mainspring GNL before eggs
hatch.
European Crane Fly: Apply Mainspring GNL between July and November to control
the fall generation of European crane fly larvae in turfgrass. An application of
Mainspring GNL in early July will also provide excellent white grub control. The higher
rate listed in Table 1 may be required to achieve control when applications are made in
November.
Spittlebugs: Mainspring GNL will provide control of two-lined spittlebug when
applications are made in spring or summer.
Turf Caterpillars: Mainspring GNL will provide excellent curative and residual
caterpillar control in turfgrass. To ensure optimum control, delay watering (irrigation) or
mowing for 24 hours after application. Mowing vegetation to lowest possible height will
ensure more consistent control. Apply in sufficient water to uniformly cover the area
being treated (a minimum of 2 gallons per 1,000 square feet is recommended for
grassy, weedy, or bare soil areas).

APPLICATION TO SOIL MEDIA
Mainspring GNL can be applied to the growing media of containerized plants to control
listed ornamental pests. Apply Mainspring GNL when pest populations are low to
prevent the increase of that population to damaging levels. Apply to moist soil media.
DO NOT apply to dry or saturated soil media. For optimal performance, DO NOT apply
drench to soil media until roots have grown after transplanting. DO NOT leach treated
soil media for at least 7 days after application or performance may be reduced. Heavy
rainfall or excessive irrigation after application could reduce insect control performance.
In general, higher rates will be needed to control insect pests on woody plants as
compared to those on herbaceous plants.
Drench Application
For drench applications, prepare a dilute drench solution by mixing Mainspring GNL in
water at the rate listed in Table 3. Apply drench solution to containers, flats, trays,
benches or beds according to the application rates given in Table 3. Drench volume
should be sufficient to thoroughly wet soil media without overflowing or leaching from
the container. Follow the drench application with moderate irrigation. Irrigate carefully
during the next 10 days to avoid loss of active ingredient from the container.

Application through Irrigation systems (Chemigation)
Mainspring GNL may be applied by injection into an irrigation system, either alone or in
combination with other pesticides or chemicals that are registered for application
through irrigation systems. Dilution ratios are normally 1:100 to 1:200, depending on the
system. Application dosages are presented in Table 4 below.
Apply this product only through micro-irrigation (individual spaghetti tube), drip irrigation,
overhead irrigation, ebb and flood irrigation, or motorized calibrated irrigation
equipment. DO NOT apply through any other type of irrigation system. Non-uniform
distribution of Mainspring GNL applied by chemigation can result in reduced product
effectiveness.
Apply Mainspring GNL under the instructions specified in the specific use
recommendations and not according to the irrigation schedule unless the events
coincide. In general, set the equipment to apply the minimum amount of water per acre.
Run the system at 8690% of the manufacturer's maximum rated travel speed.
Users should check with state and local regulatory agencies for potential use
restrictions before applying any agricultural chemical through sprinkler irrigation
equipment.
If you have questions about calibration, you should contact State Extension Service
specialists, equipment manufacturers, or other experts. A person knowledgeable of the
chemigation system and responsible for its operation, or under the supervision of the
responsible person, shall shut the system down and make necessary adjustments
should the need arise.
Using Water from Public Water Systems
DO NOT APPLY MAINSPRING GNL THROUGH ANY IRRIGATION SYSTEM
PHYSICALLY CONNECTED TO A PUBLIC WATER SYSTEM.
Public water system means a system for the provision to the public of piped water for
human consumption if such system has at least 15 service connections or regularly
serves an average of at least 25 individuals daily at least 60 days per year. Mainspring
GNL may be applied through irrigation systems which may be supplied by a public
water system ONLY if the water from the public water system is discharged into a
reservoir tank prior to pesticide introduction. There shall be a complete physical break
(air gap) between the outlet end of the fill pipe and to top or overflow rim of the reservoir
tank of at least twice the inside diameter of the fill pipe. Before beginning chemigation,
always make sure that the air gap exists and that there is no blockage of the overflow of
the reservoir tank.
Any irrigation system using water supplied from a public water system must also meet
the following requirements:

Operating Instructions for All Recommended Types of Irrigation Systems
1. The system must be calibrated to uniformly apply the rates specified. If you have
questions about calibration, you should contact State Extension Service specialists,
equipment manufacturers, or other experts.
2. The system must contain a functional check valve, vacuum relief valve, and low
pressure drain appropriately located on the irrigation pipeline to prevent water
source contamination from backflow.
3. The pesticide injection pipeline must contain a functional, automatic, quick-closing,
check valve to prevent the flow of fluid back toward the injection pump.
4. The pesticide injection pipeline must also contain a functional, normally closed,
solenoid-operated valve located on the intake side of the injection pump and
connected to the system interlock to prevent fluid from being withdrawn from the
supply tank when the irrigation system is either automatically or manually shut down.
5. The system must contain functional interlocking controls to automatically shut off the
pesticide injection pump when the water pump motor stops.
6. The irrigation line or water pump must include a functional pressure switch which will
stop the water pump motor when the water pressure decreases to the point where
pesticide distribution is adversely affected.
7. Systems must use a metering pump, such as a positive displacement injection pump
(e.g., diaphragm pump) effectively designed and constructed of materials that are
compatible with pesticides and capable of being fitted with a system interlock.
8. Do not apply when wind speed favors drift beyond the area intended for treatment.

IN-GROUND SOIL DRENCH & INJECTION APPLICATIONS
Mainspring GNL is a systemic product and will be translocated upward into the plant
from root uptake. Soil treatment application rates are listed in Table 6. To assure
optimum effectiveness, the product must be placed where the growing portion of the
target plant can absorb the active ingredient. For this reason, basal application within
one to three feet of the root flare of trees and shrubs is recommended. Application can
be made by soil injection, soil drenches and soil broadcast sprays. When making soil
applications to plants with woody stems, systemic activity will be delayed until the active
ingredient is translocated throughout the plant. In some cases, this delay could be 60
days or longer. For this reason, applications should be made prior to anticipated pest
infestation to achieve optimum levels of control.
Calculations for soil injection/drench applications of Mainspring GNL:
1: Calibrate the application equipment to determine its flow rate in gallons per minute.
2: Select an injecting/drenching volume per inch of tree diameter at breast height
(DBH) or foot of shrub height.
3: Refer to the Table 7below to determine the amount of time that is required to deliver
the desired volume per injection/drench site. The example highlighted in Table 7 shows
that 10 seconds are required per inch of tree DBH or foot of shrub height when
injecting/drenching 1 quart of solution per site using a flow rate of 1.5 gallons per
minute.
4: Determine how much solution to mix.
5: Refer to the Table 8 below to determine the amount of Mainspring GNL that must be
mixed in the desired volume of water based on the injection volume identified above.
