NON-TARGET ORGANISMS ADVISORY STATEMENT
This product is toxic to plants and may adversely impact the forage and habitat of non-target organisms, including pollinators 
in areas adjacent to the treated site. Protect the forage and habitat of non-target organisms by following label directions 
intended to minimize spray drift.
Ground Water Advisory
The active ingredients, Metolachlor and Mesotrione, are known to leach through soil into ground water under certain conditions 
as a result of label use.
These chemicals may leach if used in areas where soils are permeable, particularly where the water table is shallow.
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 groundwater. This product is classified as having high potential for reaching surface water via runoff for
several months or more after application.
A level, well maintained vegetative buffer strip between areas to which this product is applied and surface water features such 
as ponds, streams, and springs will reduce the potential loading of metolachlor and Mesotrione from runoff water and 
sediment. Runoff of this product will be reduced by avoiding applications when rainfall or irrigation is expected to occur within 
48 hours.
Mixing and Loading Instructions
Take care when using this product to prevent back siphoning into wells, spills, or improper disposal of excess pesticide, 
spray mixtures or rinsates.
Check valves or anti-siphoning devices must be used on mixing equipment.
This product may not be mixed/loaded or used within 50 feet of wells, including abandoned wells, drainage wells, and sink 
holes. Operations that involve mixing, loading, rinsing, or washing of this product into or from pesticide handling or application 
equipment or containers within 50 feet of any well are prohibited, unless conducted on an impervious pad constructed to 
withstand the weight of the heaviest load that may be positioned on or moved across the pad. Such a pad shall be designed

PRODUCT INFORMATION
MES-O-SATE Herbicide is a systemic, post-emergence herbicide for contact followed by residual control of weeds in 
Glyphosate tolerant Corn. It is also a pre-emergence herbicide for control of weeds in Grain sorghum. Following a 
post-emergence application of this product, susceptible weeds take up the herbicide through the treated foliage and cease 
growth soon after application. This product is also absorbed through the soil and/or by the foliage of emerged weeds. Complete 
death of the weeds may take up to 2 weeks.
This product provides 3 to 4 weeks of residual control of newly emerging susceptible weeds (see Table 1) through root and 
shoot absorption.

MANDATORY SPRAY DRIFT MANAGEMENT
AERIAL APPLICATIONS:
 Do not release spray at a height greater than 10 feet above the ground or vegetative canopy, unless a greater 
application height is necessary for pilot safety.
 Applicators must select nozzle and pressure that deliver me dium or coarser droplets in accordance with American 
Society of Agricultural & Biological Engineers Standard 641 (ASABE S641). If the wind speed is 10 mph or less, 
applicators must use 1/2 swath displacement upwind at the downwind edge of the field. When the wind speed is 
between 11 to 15 mph, applicators must use 3/4 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 wind speed is greater than 10 mph, the 
boom length must not exceed 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 not apply during temperature inversions.
AIRBLAST APPLICATIONS:
 Sprays must be delivered into the canopy.
 Do not apply when wind speeds exceed 15 mph at the application site.
 User must turn off outward pointing nozzles at row ends and when spraying outer row.
 Do not apply during temperature inversions.
GROUNDBOOM APPLICATIONS:
 Do not release spray at a height greater than 3 feet above the ground or cropcanopy. 
 Applicators must select nozzle and pressure that deliver medium or coarser droplets in accordance with American 
Society of Agricultural & Biological Engineers Standard 572 (ASABE S572).
 Do not apply when wind speeds exceed 15 mph at the application site.
 Do not apply during temperature inversions.
BOOMLESS GROUND APPLICATIONS:
 Applicators must select nozzle and pressure that deliver medium or coarser droplets in accordance with American 
Society of Agricultural & Biological Engineers Standard 572 (ASABE S572).
 Do not apply when wind speeds exceed 15 mph at the application site.
 Do not apply during temperature inversions.


SPRAY DRIFT ADVISORIES
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT.
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS.
IMPORTANCE OF DROPLET SIZE
An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide target pest control. While 
applying larger droplets will reduce spray drift, the potential for drift will be greater if applications are made improperly or under 
unfavorable environmental conditions.
Controlling Droplet Size - Ground Boom
• Volume- Increasing the spray volume so that larger droplets are produced will reduce spray drift. Use the highest practical 
spray volume for the application. If a greater spray volume is needed, consider using a nozzle with a higher flow rate.

Page 6 of 16 
• Pressure- Use the lowest spray pressure recommended for the nozzle to produce the target spray volume and droplet 
size.
• Spray Nozzle- Use a spray nozzle that is designed for the intended application. Consider using nozzles designed to reduce 
drift.
Controlling Droplet Size - Aircraft
• Adjust Nozzles- Follow nozzle manufacturer’s recommendations for setting up nozzles. Generally, to reduce fine droplets, 
nozzles should be oriented parallel with the airflow inflight.
BOOM HEIGHT – GROUND BOOM
For ground equipment, the boom should remain level with the crop and have minimal bounce.
RELEASE HEIGHT - AIRCRAFT
Higher release heights increase the potential for spray drift.
SHIELDED SPRAYERS
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify that the shields are 
not interfering with the uniform deposition of the spray on the target area.
TEMPERATURE AND HUMIDITY
When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation.
TEMPERATURE INVERSIONS
Drift potential is high during a temperature inversion. Temperat ure inversions are characterized by increasing temperature 
with altitude and are common on nights with limited cloud cover and light to no wind. The presence of an inversion can be 
indicated by ground fog or by the movement of smoke from a ground source or an aircraft smoke generator. 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 airmixing.
WIND
Drift potential generally increases with wind speed. Applicators need to be familiar with local wind patterns and terrain that
could affect spray drift.
HANDHELD TECHNOLOGY APPLICATIONS
Take precautions to minimize spray drift.
Boomless Ground Applications: 
Setting nozzles at the lowest effective height will help to reduce the potential for spray drift.
WEED RESISTANCE MANAGEMENT
METOLACHLOR GROUP 15 HERBICIDE 
GLYPHOSATE GROUP 9 HERBICIDE 
MESOTRIONE GROUP 27 HERBICIDE 
For resistance management, this product is a Group 15, 9 and 27 modes of action herbicides. Any weed population may 
contain or develop plants naturally resistant to this product and other Group 15, 9 and 27 modes of action herbicides. The 
resistant biotypes may dominate the weed population if these herbicides are used repeatedly in the same field. Appropriate 
resistance management strategies should be followed.
To delay herbicide resistance, take one or more of the following steps:
 Rotate the use of this product or other Group 15, 9 and 27 herbicides within a growing season sequence or among growing 
seasons with different herbicide groups that control the same weeds ina field. 
 Use tank mixtures with herbicides from a different group if such use is permitted; where information on resistance in target 
weed species is available, use the less resistance-prone partner at a rate that will control the target weed(s) equally as well 
as the more resistance-prone partner. Consult your local extension service or certified crop advisor if you are unsure as to 
which active ingredient is currently less prone toresistance. 
 Adopt an integrated weed-management program for herbicide use that includes scouting and uses historical information 
related to herbicide use and crop rotation, and that considers tillage (or other mechanical control methods), cultural ( e.g.,
higher crop seeding rates; precision fertilizer application method and timing to favor the crop and not the weeds), biological 
(weed-competitive crops or varieties) and other managementpractices.
 Scout after herbicide application to monitor weed populations for early signs of resistance development. Indicators of 
possible herbicide resistance include: (1) failure to control a weed species normally controlled by the herbicide at the dose
applied, especially if control is achieved on adjacent weeds; (2) a spreading patch of non-controlled plants of a particular 
weed species; (3) surviving plants mixed with controlled individuals of the same species. If resistance is suspected, prevent

Page 7 of 16 
weed seed production in the affected area by an alternative herbicide from a different group or by a mechanical method 
such as hoeing or tillage. Prevent movement of resistant weed seeds to other fields by cleaning harvesting and tillage 
equipment when moving between fields, and planting cleanseed. 
 If a weed pest population continues to progress after treatment with this product, discontinue use of this product, and switch 
to another management strategy or herbicide with a different mode of action, if available.
 Contact your local extension specialist or certified crop advisors for additional pesticide resistance-management and/or 
integrated weed-managementrecommendations for specific crops and weed biotypes.
 For further information or to report suspected resistance, contact Drexel Chemical Company representatives at (901) 774-
4370.
Triazine and Acetolactate Synthase (ALS) Resistance
Naturally occurring biotypes of certain broadleaf and grass weed species with resistance to triazine or ALS herbicides are 
known to exist. If weed biotypes resistant to triazine or ALS i nhibitors are present in the field, this product will control th em if 
they are listed in Table 1.
Glyphosate Resistance
Some naturally occurring weed biotypes resistant to Glyphosate may exist through normal genetic variability in any weed 
population. The repeated use of herbicides with the same mode of action is known to lead under certain conditions to a 
selection of resistant weeds. Certain agronomic practices reduce the likelihood that resistant weed populations will develop 
and integrated strategies are known to manage such problem weeds.
Glyphosate is one of the active ingredients in this product, thus, Glyphosate resistance management is critical. This product
will control broadleaf weeds that are showing increased tolerance or resistance to Glyphosate. When applying this product to 
broadleaf weeds that are suspected or known to be resistant to Glyphosate, tank-mix with Atrazine or Dicamba to provide an 
additional mode of action. It is the pesticide user’s responsibility to ensure that all products are registered for the intended
use. Read and follow the applicable restrictions and limitations and directions for use on all product labels involved in tank-
mixing. Users must follow the most restrictive directions for use and precautionary statements of each product in the tank-
mixture.
This product will not provide control of emerged grasses that are resistant to Glyphosate. For control of Glyphosate resistant
grass weeds, a weed control program that includes a pr e-emergence grass herbicide will reduce the dependence on 
Glyphosate.
Best Weed Management practice includes the diversification ofGlyphosate dependent weed control programs with alternative 
mode of action herbicides or cultural practices.
 In Roundup Ready Corn and Roundup Ready Soybeans systems, do not use more than two applications of a 
Glyphosate based herbicide over a two-year period. Diversify with alternative mode of action herbicides and/or 
cultural practices.
 In Roundup Ready Cotton, a maximum of three applications of a Glyphosate based herbicide may be used if
employing in-crop cultivation and/or residualherbicides. 
 Use alternative (non-Glyphosate) burndown and/or residu al herbicides for Roundup Ready crops likely to require 
more than one application of Glyphosate.
 To help manage Roundup Ready resistant volunteers, rotate Roundup Ready crops with conventional or non-
Roundup Ready crops.
 Use full labeled rates of Glyphosate and tank-mix partners. Minimize weedescapes. 
 Monitor treated weed populations for any loss of fieldefficacy. 
 Contact your local extension specialist, certified crop advisor and/or Crop Protection representative for herbicide 
resistance management and/or integrated weed management practices for specific crops and resistant weed 
biotypes.

APPLICATION PROCEDURES
Refer to the “CROP USE DIRECTIONS” section for specific crop instructions.
USE OF ADJUVANTS
For post-emergence applications to Glyphosate tolerant Corn or burndown applications to Grain sorghum, add a nonionic 
surfactant at 1 to 2 quarts per 100 gallons of water (0.25 to 0.5% v/v) to the spray solution. Use the higher rate of nonionic 
surfactant when weeds are growing under stress conditions (e.g. cool temperatures, dry weather, etc.).

Page 11 of 16 
In addition to nonionic surfactant, add spray grade ammonium sulfate (AMS) at 8.5 to 17.0 pounds per 100 gallons of water. 
When using liquid AMS products, use a rate that delivers an AMS equivalent of 8.5 to 17.0 pounds per 100 gallons of water.
The use of this product with urea ammonium nitrate (UAN) instead of AMS will result in crop injury and reduced grass weed 
control.
GROUND APPLICATION
Ensure that spray nozzles are uniformly spaced, same size and type and provide accurate and uniform application. Use spray 
nozzles that provide medium to coarse droplet size to provide good coverage and avoid drift. Good weed coverage is essential 
for optimum weed control. Base boom height for broadcast over-the-top applications on the height of the crop – at least 15 
inches above the crop canopy.
Flat fan (80o or 110o) or Turbo Tee Jet nozzles will provide optimum coverage. Do not use flood jet nozzles or controlled 
droplet application equipment for applications of this product.
Nozzles may be angled 45o forward or backward to enhance penetration of the crop and provide better coverage. Ensure that 
all in-line strainer and nozzle screens in the sprayer are 50 mesh or coarser.
Apply this product in a spray volume of 10 to 30 gallons per acre. Use a pump that can maintain a pressure of at least 35 to 
40 psi at the nozzles (check nozzle manufacturer’s instructions) and provide proper agitation within the tank to keep the 
product dispersed. Lower pressures may be used with extended range or drift reduction nozzles. When weed foliage is dense, 
use a minimum of 15 gallons per acre.
Always ensure that agitation is maintained until spraying is completed even if spraying is stopped for brief periods. If the 
agitation is stopped for more than 5 minutes, re-suspend the spray solution by running on full agitation prior to spraying.
CLEANING EQUIPMENT AFTER APPLICATION
Special attention must be given to cleaning equipment before spraying a crop other than Glyphosate tolerant Corn or Grain 
sorghum. Mix only as much spray solution as needed.
1. Flush tank, hoses, boom and nozzles with clean water.
2. Prepare a cleaning solution of 1 gallon of household ammonia per 25 gallons of water. Many commercial spray tank 
cleaners may be used.
3. Use a pressure washer to clean the inside of the spray tank with this solution. Take care to wash all parts of the tank, 
including the inside top surface. If a pressure washer is not available, completely fill the sprayer with the cleaning solution 
to ensure contact of the cleaning solution with all internal surfaces of the tank and plumbing. Start agitation in the sprayer
and thoroughly re-circulate the cleaning solution for at least 15 minutes. Remove all visible deposits from the spraying 
system.
4. Flush hoses, spray lines and nozzles for at least 1 minute with the cleaning solution.
5. Dispose of rinsate from steps 1 to 3 in an appropriate manner.
6. Repeat steps 2 to 5.
7. Remove nozzles, screens, and strainers and clean separately in the ammonia solution after completing the above 
procedures.
8. Rinse the complete spraying system with clean water.
AERIAL APPLICATION
This product may be applied aerially for post-emergence weed control in Glyphosate tolerant Corn and pre-plant or pre- 
emergence weed control in Grain sorghum only in the following states: Alabama, Arizona, Arkansas, California, Colorado, 
Connecticut, Delaware, Florida, Georgia, Idaho, Illinois, Indiana, Iowa, Kansas, Kentucky, Louisiana, Maine, Maryland, 
Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nevada, New Hampshire, New Jersey, New Mexico, 
New York, North Carolina, North Dakota, Nebraska, Ohio, Oklahoma, Oregon, Pennsylvania, Rhode Island, South Carolina, 
South Dakota, Tennessee, Texas, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin and Wyoming.
Applications must be made in a minimum of 2 gallons of water per acre.
Restrictions: For aerial application, use only nozzles producing coarse-ultra coarse droplets. Do not use nozzles producing 
fine-medium size droplets.
ADDITIONAL SPRAY DRIFT PRECAUTIONS FOR AERIAL APPLICATION

Page 12 of 16 
The distance of the outer-most nozzles on the boom must not exceed three-fourths the length of the wingspan or rotor.
Nozzles must always point backward parallel with the air stream and never be pointed downwards more than 45 degrees. 
Where states have more stringent regulations, they must be observed.
Spray must be released at the lowest height consistent with effective weed control and flight safety.
For best results, each specific aerial application vehicle used should be quantifiably pattern tested initially for aerial application 
of this product and every year thereafter.
For some use patterns, reducing the effective boom length to less than three-fourths of the wingspan or rotor length may 
further reduce drift without reducing swath width.
Do not make applications at a height greater than 10 feet above the top of the largest plants unless a greater height is required 
for aircraft safety. Making applications at the lowest height that is safe reduces exposure of droplets to evaporation and wind.
When applications are made with a crosswind, the swath will be displaced downwind. Therefore, on the up and downwind 
edges of the field, the applicator must compensate for this displacement by adjusting the path of the aircraft upwind. Swath 
adjustment distance should increase with increasing drift potential (higher wind, smaller drops, etc.).
Drift potential is lowest between wind speeds of 2 to 10 mph. However, many factors, including droplet size and equipment 
type determine drift potential at any given speed. Avoid application below 2 mph due to variable wind direction and high 
inversion potential. Note: Local terrain can influence wind patterns. Every applicator should be familiar with local wind patterns 
and how they affect drift.
When making applications in low relative humidity, set up equipment to produce larger droplets to compensate for evaporation. 
Droplet evaporation is most severe when conditions are both hot anddry.
Avoid applying during a temperature inversion, because drift poten tial is high. Temperature inversions restrict vertical air 
mixing, which causes small suspended droplets to remain in a concentrated cloud. This cloud can move in unpredictable 
directions due to the light variable winds common during inversions. Temperature inversions are characterized by increasing 
temperatures 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, 
inversions can also be identified by the movement of smoke from a ground source or an aircraft smoke generator. Smoke that 
layers and moves laterally in a connected cloud (under low wind conditions) indicates an inversion, while smoke that moves 
upwards and rapidly dissipates indicates good vertical airmixing.
The pesticide should only be applied when the potential for drift to adjacent sensitive areas (e.g., residential areas, bodies of 
water, known habitat for threatened or endangered species, non-t arget crops) is minimal (e.g., when wind is blowing away 
from the sensitive areas).
TO PREVENT OFF-SITE MOVEMENT DUE TO RUNOFF OR WIND EROSION
Do not apply under conditions which favor runoff or wind erosion of soil containing this product to non-target areas. To prevent 
off-site movement due to runoff or wind erosion, avoid treati ng powdery dry or light soils when conditions are favorable for 
wind erosion. Under these conditions, ensure that the soil surface is settled by rainfall or irrigation first. Do not apply to
impervious substrates such as paved or highly compacted surfaces. Do not use tailwater from the first flood or furrow irrigation 
of treated fields to treat non-target crops unless at least one-half inch of rainfall has occurred between application and the first 
irrigation.
MIXING PROCEDURES

CROP USE DIRECTIONS
CORN (GLYPHOSATE TOLERANT)
This product may be applied post-emergence only in Glyphosate tolerant Corn (Roundup Ready) for control of the weeds 
listed in Table 1. When Glyphosate tolerant Corn is grown under no-till conditions, control all emerged weeds at the time of 
Corn planting with a Glyphosate or Paraquat based herbicide program. Following a burndown weed control application and 
after Glyphosate tolerant Corn emergence, this product can be applied post-emergence to control the weeds listed in Table 
1.
PRE-EMERGENCE
This product is specifically formulated for post-emergence in crop use and does not contain a Corn safener. Therefore, this 
product is not labeled for early pre-plant or pre-emergence applications.
THIS PRODUCT ALONE - POST-EMERGENCE
This product may be applied at a rate of 3.6 to 4.0 pints per acre from Corn emergence up to 30 inches in height or the 8 leaf 
stage of Corn growth. Apply this product to actively growing weeds listed inTable 1. For the best protection of the Corn crops 
yield potential, apply this product before weeds exceed 4 inches in height, length or diameter. Use the higher end of the use 
rate range of this product (i.e., 4.0 pts./Ac.) when weeds are stressed or weed populations are dense.
Apply this product with a nonionic surfactant and ammonium sulfate (AMS). See the “ADJUVANTS” section for specific 
instructions.
Visible effects on annual weeds occur within 2 to 4 days after application. Effects on perennial weeds may take 7 days or 
longer. Extremely cool or cloudy weather following treatment may slow activity.
Weeds susceptible to Metolachlor or Mesotrione which emerge soon after application of this product will be controlled after 
they absorb the herbicides from the soil. The active ingredients contained in this product are in adequate amounts to provide 
3 to 4 weeks of residual weed control extending through crop canopy. If an activating rain (0.25 inches) is not received within 
7 to 10 days after the post-emergence application, residual weed control will bereduced.
Applying this product at rates less than 3.6 pints per acre may result in incomplete weed control, as well as less residual weed 
control. Using reduced rates of this product also increases the risk for the development of weed resistant biotypes. See the 
“WEED RESISTANCE MANAGEMENT” section of this label for specific instructions.
THIS PRODUCT – SEQUENTIAL WEED CONTROL
This product may be applied as the post-emergence component of a two-pass weed control program. Apply pre-emergence 
products at labeled rates and follow with a post-emergence application of this product at 3.6 to 4.0 pints per acre. Do not 
reduce the rate of this product when applied in a sequential program with pre-emergence products containing Mesotrione.
This product may also be applied following pre-emergence application of products containing Mesotrione not to exceed 0.094 
pound of Mesotrione a.i. per acre per application and 0.24 pound of Mesotrione a.i. per acre per year.
Apply this product with a nonionic surfactant and ammonium sulfate (AMS). See the “ADJUVANTS” section for specific 
adjuvant instructions.

applicable restrictions and limitations and directions for use on all product labels involved in tank-mixing. Users must follow 
the most restrictive directions for use and precautionary statements of each product in the tank-mixture.
THIS PRODUCT – TANK-MIXED WITH ATRAZINE
Apply this product at 3.6 to 4.0 pints per acre in tank-mixture with Atrazine. If weeds are more than 4 inches tall or for improved 
broadleaf weed control, add Atrazine at a rate of 0.25 to 2.0 pound s a.i. per acre. Alternatively, Atrazine in the form of dry 
flowable (DF) or water dispersible granules (WDG) containing 0.9 pound a.i. per pound of the product may be mixed with this 
product in place of Atrazine in liquid form containing 4 pounds a.i. per gallon of the product at a rate that delivers 0.25 to 2 .0 
pounds a.i. per acre. Atrazine rates above 0.5 pound a.i. per acre may result in Glyphosate antagonism and reduced grass 
control.
Apply this product in tank-mixture with Atrazine with a nonionic surfactant and ammonium sulfate (AMS). See the
“ADJUVANTS” section of this label for specific instructions.
When tank-mixing or sequentially applying atrazine or products containing atrazine with this product to Glyphosate tolerant 
Corn, do not exceed an application rate of 2.0 pounds Atrazine a.i. per acre for any single application and the total pounds of 
atrazine applied (lbs. a.i./Ac.) must not exceed 2.5 pounds a.i. per acre per year. It is the pesticide user’s responsibility t o 
ensure that all products are registered for the intended use. Read and follow the applicable restrictions and limitations and
directions for use on all product labels involved in tank-mixing. Users must follow the most restrictive directions for use and 
precautionary statements of each product in the tank-mixture.
If no atrazine was applied prior to Corn emergence, apply a maximum of 2.0 pounds a.i. per acre broadcast. If a post-
emergence treatment is required following an earlier herbicide application, the total Atrazine applied may not exceed 2.5 
pounds a.i. per acre per calendar year.
Do not apply any Atrazine formulation if Corn is greater than 12 inches tall.
THIS PRODUCT – TANK-MIXED WITH PRODUCTS CONTAINING DICAMBA
Tank-mix this product at 3.6 to 4 pints per acre with products containing Dicamba plus nonionic surfactant at 1 quart per 100 
gallons plus spray grade ammonium sulfate (AMS) for improved control of difficult broadleaf weeds as a post-emergence 
application in Glyphosate tolerant Corn.
It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the
applicable restrictions and limitations and directions for use on all product labels involved in tank-mixing. Users must follow 
the most restrictive directions for use and precautionary statements of each product in the tank-mixture.
If compatibility of the tank-mix combination is not known, test the compatibility of any tank-mix combination on a small scale 
such as a jar test before actual tank-mixing.
USE PRECAUTIONS
1. Temporary crop response (transient bleaching) from post-emergence applications to Glyphosate tolerant Corn may occur 
under extreme weather conditions or when the crop is suffer ing from stress. Corn quickly outgrows these effects and 
develops normally.
2. If additional Glyphosate is tank-mixed or applied sequentially with this product as a post-emergence treatment in Glyphosate 
tolerant Corn, refer to the specific Glyphosate label for in crop raterestrictions.
It is the pesticide user’s responsibility to ensure that all products are registered for the intended use. Read and follow the

GRAIN SORGHUM
This product can be applied pre-plant non-incorporated (up to 21 days before planting) up through pre-emergence for weed 
control in Sorghum. This product will control the emerged weeds listed in the Table 1 and will provide residual control of the
weeds listed in Table 3.
The Sorghum seed must be treated with a protectant that is effective for safening Metolachlor to Sorghum. Applying this 
product pre-plant or pre-emergence to Sorghum that is not seed protected for applications to Metolachlor will result in crop 
death. Applying this product post-emergence to Sorghum will result in crop death.
Apply this product as a broadcast non-incorporated spray at a rate of 4 to 6 pints per acre beginning at 21 days before planting 
and up through planting but prior to Sorghum emergence. Applying this product less than 7 days before Sorghum planting will 
increase the risk of crop injury, especially if irrigation or rainfall is received following the application. Injury symptoms in clude 
temporary bleaching of newly emerging Sorghum leaves or in extreme conditions, stunting or partial stand loss. Applying this 
product more than 7 days (but not more than 21) prior to Sorghum planting will reduce the risk of crop injury.
If this product is applied prior to planting, minimize disturbance of the herbicide treated soil barrier during the planting process 
in order to lessen the potential for poor weed control in the disturbed soilzone.
SPLIT APPLICATION
This product may also be applied as a split application to Grain sorghum. For a split application program, apply the first 
application as a non-incorporated early pre-plant (7 to 21 days before planting) treatment followed by a second application of 
this product as a pre-emergence application prior to Sorghum emergence. The total amount of this product applied in the split 
application program cannot exceed 6 pints per acre perseason.
For control of emerged weeds listed in Table 1, add a nonionic surfactant (NIS) type adjuvant at a rate of 0.25 to 0.5% v/v (1 
to 2 qts./100 gals.) to the spray solution. Use the higher NIS rate of 0.5% v/v under adverse environmental conditions (high 
temperatures and/or low humidity). In addition to NIS, a spra y grade ammonium sulfate (AMS) at a rate of 8.5 to 17 pounds 
per 100 gallons of spray may be added to the solution for improved control of emerged weeds.
This product can be applied sequentially or in tank-mixture with other herbicides registered for use in Grain sorghum. Always 
refer to labels of the tank mix partners for use directions, precautions and restrictions.
GRAIN SORGHUM USE RESTRICTIONS
1. Do not apply more than 6 pints of this product per acre per growing season.
2. Do not apply this product to Sorghum grown on sandy soils (sand, sandy loam or loamy sand).
3. Do not apply this product to emerged Grain sorghum or plant death will occur.
4. Do not use this product in the production of Forage sorghum, Sweet sorghum (sorgo), Sudangrass, Sorghum-
Sudangrass hybrids or dual purpose Sorghum.
5. Sorghum seed must be treated with Concep® III herbicide safener prior to planting or severe crop injury may occur.
6. In the state of Texas, do not apply this product to Sorghum grown South of Interstate 20 (I-20) or East of Highway 277.
WEEDS CONTROLLED IN GRAIN SORGHUM
When applied as directed in this label, this product at 6 pints per acre will provide pre-emergence control or partial control the 
weeds listed in Table 3. Optimum weed control will be obtained if this product is applied according to all label directions.
If a significant rainfall does not occur within 7 days after application, weed control may be decreased. If irrigation is available, 
apply 0.5 to 1 inch of water. If irrigation is not available, a uniform shallow cultivation as soon as weeds emerge will provid e 
improved control.
