When handlers use closed systems, enclosed cabs, or ai rcraft in a manner that meets the requirements 
listed in the Worker Protection Standard (WPS) for agricultural pesti cides [40 CFR 170.607(d-f)], the 
handler PPE requirements may be reduced or modified as specified in the WPS. 
 
User Safety Recommendations 
Users should: 
x Remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and put on 
clean clothing. 
x Remove PPE immediately after handling this pr oduct. Wash the outside of gloves before 
removing. As soon as possible, wash thoroughly and change into clean clothing. 
 
Environmental Hazards 
Do not apply directly to water, to areas where surface water is present, or to intertidal areas below the 
mean high water mark. Do not contaminate water when disposing of equipment wash water or rinsate. 
 
Groundwater Advisory 
S-metolachlor is known to leach through soil into groundwater under certain conditions as a result of label 
use. This chemical may leach into groundwater if used in areas where soils are permeable, particularly 
where the water table is shallow. 
 
Metribuzin is a chemical which can travel (seep or leach) through soil and can contaminate groundwater 
which may be used as drinking water. Metribuzin has been found in groundwater as a result of agricultural 
use. Users are advised not to apply metribuzin where the water table (groundwater) is close to the surface 
and where the soils are very permeable, i.e., well-drained soils such as loamy sands. Your local 
agricultural agencies can provide further information on the type of soil in your area and the location of 
groundwater.

Surface Water Advisory 
This product may impact surface water quality due to runoff of rain water. This is especially true for poorly 
draining soils and soils with shallow ground water. This product is classified as having high potential for 
reaching surface water via runoff for several weeks or months 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 S-metolachlor from runoff water and 
sediment. Runoff of this product will be reduced by av oiding applications when rainfall or irrigation is 
expected to occur within 48 hours. 
 
Non-target Organism Advisory 
This product is toxic to plants and may adversely im pact 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. 
 
Mixing/Loading Instructions 
Care must be taken when using this product to prevent back-siphoning into wells, spills, or improper 
disposal of excess pesticide, spray mixtures, or rinsate. 
 
Check-valves or antisiphoning devices must be used on all mixing and/or irrigation equipment. 
 
This product must not be mixed or loaded within 50 ft. of perennial or intermittent streams and rivers, 
natural or impounded lakes and reservoirs. This product may not be mixed/loaded or used within 50 ft. of 
all 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 ft. 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 and maintained to contain any product spills or equipment leaks, container or equipment 
rinse or wash water, and rain water that may fall on the pad. Surface water shall not be allowed to either 
flow over or from the pad, which means the pad must be self-contained. The pad shall be sloped to 
facilitate material removal. An unroofed pad shall be of sufficient capacity to contain at a minimum 110% 
of the capacity of the largest pesticide container or application equipment on the pad. A pad that is covered 
by a roof of sufficient size to completely exclude precipitation from contact with the pad shall have a 
minimum containment capacity of 100% of the capacity of the largest pesticide container or application 
equipment on the pad. Containment capacities as described above shall be maintained at all times. The 
above-specified minimum containment capacities do no t apply to vehicles when delivering pesticide 
shipments to the mixing/loading site.

PRODUCT INFORMATION 
AGH19016 is a soil applied, pre-emergent herbicide containing two active ingredients with different modes 
of action, which assists in the management of herbicide resistance. 
 
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: 
x Avoid treating powdery dry or light sand soils when conditions are favorable for wind erosion. Under 
these conditions, the soil surface should first be settled by rainfall or irrigation. 
x Do not apply to impervious substrates, such as paved or highly compacted surfaces. 
x Do not use tailwater from the first flood or furrow irrigation of treated fields to treat non-target crops, 
unless at least ½ inch of rainfall has occurred between application and the first irrigation. 
 
Mixing Instructions 
Prepare no more spray mixture than is needed for the immediate operation. Thoroughly clean the spray 
equipment before using AGH19016. Vigorous agitation is necessary to maintain uniformity of the spray 
mixture. Maintain maximum agitation throughout the spraying operation. Do not allow spray mixture to 
stand overnight in the spray tank. Flush the spray equipment thoroughly following each use and apply the 
rinsate to a previously treated area.

Page 5 of 21 
 
 
Application in Water or Fluid Fertilizers 
AGH19016 Alone: Add 1/3 of the required amount of water or fluid fertilizer to the spray or mixing tank. 
With the agitator running, add AGH19016 into the spray tank. Continue agitation while adding the remainder 
of the water or fluid fertilizer. Begin application of the spray solution after the AGH19016 has completely 
dispersed in the water or fluid fertilizer. Maintain agitation until all of the mixture has been applied. 
 
Tank Mixtures 
This product may be tank mixed with other products at appropriate rates as long as tank mixing is not 
prohibited by the label(s) of the tank mix partner products, or as otherwise noted within the specific crop 
use directions for this product, and the tank mix partner products are labeled for the timing and method of 
application for the use site to be treated. Do not exceed any label dosage rates. 
It is the pesticide user’s responsibility to ensure that all products in the mixtures 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 you have no previous experience mixing these produc ts under your conditions, perform a compatibility 
test before attempting large-scale mixing (see the Compatibility Test section of this label). 
 
Mixing Instructions (AGH19016 + Tank Mix Partner): Add 1/3 of the required amount of water or fluid 
fertilizer to the mix tank. Start the agitator running before adding any tank mix partners. In general, add 
tank mix partners in this order: products packaged in water-soluble packaging, wettable powders, wettable 
granules (dry flowables), liquid flowables, liquids such as AGH19016, and emulsifiable concentrates. 
 
Always allow each tank mix partner to become fully dispersed before adding the next product. Provide 
sufficient agitation while adding the remainder of the water. Maintain agitation until all of the mixture has 
been applied. 
 
When using AGH19016 in tank mixtures with products packaged in water-soluble packaging: 
1) Add all products in water-soluble packaging to the tank and mix with plain water before any other 
tank mix partner, including AGH19016. Allow the wa ter-soluble packaging to completely dissolve 
and the product(s) to completely disperse before adding any other tank mix partner to the tank. 
2) Water-soluble packets will not properly dissolve in most spray solutions that contain fluid fertilizers. 
 
AGH19016 is compatible with most common tank mix partners. However, the physical compatibility of 
AGH19016 with tank mix partners should be tested before use. To determine the physical compatibility 
of AGH19016 with other products, use a jar test, as described below. 
 
Compatibility Test 
A jar test is recommended before tank mixing to ensure compatibility of AGH19016 with other pesticides. 
The following test assumes a spray volume of 25 gal./A. For other spray volumes, make appropriate 
changes in the ingredients. 
 
Note: Nitrogen solutions or complete fluid fertilizers may replace all or part of the water in the spray. 
Because liquid fertilizers vary, even within the same analysis, always check compatibility with 
pesticide(s) before use. Incompatibility of tank mixtures is more common with suspensions of fertilizer 
and pesticides. 
 
Test Procedure 
1) Add 1.0 pt. of carrier (fertilizer or water) to each of 2 one qt. jars with tight lids. 
Note: Use the same source of water that will be used for the tank mix and conduct the test at the 
temperature the tank mix will be applied. 
2) To one of the jars, add ¼ tsp. or 1.2 milliliters of a compatibility agent approved for this use (¼ tsp. 
is equivalent to 2.0 pt./100 gal. spray). Shake or stir gently to mix.

Page 6 of 21 
 
3) To both jars, add the appropriate amount of pesticide(s) in their relative proportions based on label 
rates. If more than one pesticide is used, add them separately with dry pesticides first, flowables 
next, and emulsifiable concentrates last. After each addition, shake or stir gently to thoroughly mix. 
4) After adding all ingredients, put lids on and tighten, and invert each jar ten times to mix. Let the 
mixtures stand 15-30 minutes and then look for separat ion, large flakes, precipitates, gels, heavy 
oily film on the jar, or other signs of incompatibility. Determine if the compatibility agent is needed 
in the spray mixture by comparing the two jars. If either mixture separates, but can be remixed 
readily, the mixture can be sprayed as long as good agitation is used. If the mixtures are 
incompatible, test the following methods of improving compatibility: (a) Slurry the dry pesticide(s) 
in water before addition, or (b) add ½ the compatibility agent to the fertilizer or water and the other 
½ to the emulsifiable concentrate or flowable pesticide before addition to the mixture. If 
incompatibility is still observed, do not use the mixture. 
5) After compatibility testing is complete, dispose of any pesticide wastes in accordance with the 
Storage and Disposal section in this label. 
 
Ground Application 
Apply AGH19016 alone or in tank mixtures by ground equipment in a minimum of 10 gallons of spray 
mixture per acre, unless otherwise specified. 
 
Use sprayers that provide accurate and uniform application. Calibrate the sprayer before use at the 
beginning of the season. For AGH19016 tank mixtures with wettable powder or dry flowable formulations, 
screens and strainers should be no finer than 50-mesh. 
 
Calculate the amount of herbicide needed for band treatment by the formula: 
Band width in inches X broadcast rate per acre = amount needed per acre of field Row width in inches 
 
Center Pivot Irrigation Application 
If applying through chemigation, apply this product only through a center pivot irrigation system. Do not 
apply this product through any other type of irrigation syste m. Crop injury, lack of effectiveness, or illegal 
pesticide residues in the crop can result from non- uniform distribution of tr eated water. If you have 
questions about calibration, contact State Extensi on specialists, equipment manufacturers, or other 
experts. Do not connect an irrigation system (including greenhouse systems) used for pesticide application 
to a public water system, unless the pesticide label-prescribed safety devices for public water systems are 
in place. 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. 
 
Operating Instructions 
x 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. 
x The pesticide injection pipeline must contain a functional, automatic, quick-closing check-valve to 
prevent the flow of fluid back toward the injection pump. 
x 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. 
x The system must contain functional interlocking controls to automatically shut off the pesticide 
injection pump when the water pump motor stops. 
x 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.

Page 7 of 21 
 
x Systems must use a metering pump, such as a positive displacement injection pump (e.g., 
diaphragm pump or piston pump), effectively designed and constructed of materials that are 
compatible with pesticides and capable of being fitted with a system interlock. 
x Do not apply when wind speed favors drift beyond the area intended for treatment. 
x Prepare a mixture with a minimum of 1-part water to 1-part herbicide(s) and inject this mixture into 
the center pivot system. Injecting a larger volume of a more dilute mixture per hour will usually 
provide more accurate calibration of metering equipment. Maintain sufficient agitation to keep the 
herbicide in suspension. 
x Meter into irrigation water during entire period of water application. 
x Apply in ½ - 1 inch of water. Use the lower water volume (½ inch) on coarse-textured soils and the 
higher volume (1 inch) on fine-textured soils. More than 1 inch of water at application may reduce 
weed control by moving the herbicide below the effective zone in the soil. 
 
Precaution for center pivot applications: Where sprinkler distribution patterns do not overlap 
sufficiently, unacceptable weed control may resul t. Where sprinkler distribution patterns overlap 
excessively, crop injury may result. 
 
Aerial Application 
Apply AGH19016 in water using a minimum spray volume of 2 gal./A. Avoid application under conditions 
where uniform coverage cannot be obtained or where excessive spray drift may occur. Make applications 
at a maximum height of 10 ft. above the crop canopy. 
 
Do not apply this product in a way that will contact workers or other persons, either directly or through drift. 
Only protected handlers may be in the area during application. 
 
Spray Drift Management 
 
Mandatory Spray Drift Management 
Aerial Applications: 
x 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. 
x For applications prior to the emergence of crops and target weeds, applicators are required to 
select the nozzle and pressure that deliver coarse or coarser droplets (ASABE S641). 
x For all other applications, applicators are required to select the nozzle and pressure that deliver 
medium or coarser droplets (ASABE S641). 
x Nozzles must always point backward parallel with the air stream and never be pointed downwards 
more than 45 degrees. 
x If the wind speed is 10 miles per hour or less, applicators must use ½ swath displacement upwind 
at the downwind edge of the field. When the wind speed is between 11-15 miles per hour, applicators 
must use ¾ swath displacement upwind at the downwind edge of the field. 
x 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 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. 
x Do not apply during temperature inversions. 
Ground Boom Applications: 
x User must only apply with the release height recommended by the manufacturer, but no more than 
4 feet above the ground or crop canopy. 
x Applicators are required to select the nozzle and pressure that deliver medium or coarser droplets 
(ASABE S572). 
x Do not apply when wind speeds exceed 15 miles per hour at the application site. 
x Do not apply during temperature inversions.

Page 8 of 21 
 
Boomless Ground Applications: 
x Applicators are required to select the nozzle and pressure that deliver medium or coarser droplets 
(ASABE S572). 
x Do not apply when wind speeds exceed 15 miles per hour at the application site. 
x 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 
x 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. 
x Pressure - Use the lowest spray pressure recommended for the nozzle to produce the target 
spray volume and droplet size. 
x Spray Nozzle - Use a spray nozzle that is designed for the intended application. Consider using 
nozzles designed to reduce drift. Solid stream nozzles oriented straight back produce the largest 
droplets and the lowest drift. 
x Number of nozzles - Use the minimum number of nozzles that provide uniform coverage. 
x Nozzle Orientation - Orienting nozzles so that the spray is released parallel to the airstream 
produces larger droplets than other orientations and is the recommended practice. Significant 
deflection from horizontal will reduce droplet size and increase drift potential. 
Controlling Droplet Size – Aircraft 
x Adjust Nozzles - Follow nozzle manufacturers’ recommendations for setting up nozzles. 
x Generally, to reduce fine droplets, nozzles should be oriented parallel with the airflow in flight. 
 
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. Do not release spray at a height greater than 
10 feet above the ground or vegetative crop canopy, unless a greater application height is required for 
aircraft safety. Making applications at the lowest height that is safe reduces exposure of droplets to 
evaporation and wind. 
Swath Adjustment 
When applications are made with a crosswind, the swath will be displaced downward. 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.) 
Shielded Sprayers 
Shielding the boom or individual nozzles can reduce sp ray 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.

Page 9 of 21 
 
Temperature Inversions 
Drift potential is high during a temperature inversio n. Temperature 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 air mixing. 
Wind 
Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND 
CONDITIONS. Drift potential is lowest between wind speeds of 2-10 mph. However, many factors, 
including droplet size and equipment type determine drift potential at any given speed. Application should 
be avoided 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 spray drift. 
Sensitive Areas 
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-target crops) is minimal 
(e.g. when wind is blowing away from the sensitive areas). 
Boomless Ground Applications 
Setting nozzles at the lowest effective height will help to reduce the potential for spray drift. 
Handheld Technology Applications: 
Take precautions to minimize spray drift. 
Cleaning Equipment After Application 
Because some non-labeled crops are sensitive to low rates of AGH19016, special attention must be given 
to cleaning equipment before spraying a crop other than those registered for use and on this label. Mix only 
as much spray solution as needed. Immediately after spraying, clean equipment thoroughly using the 
following procedure: 
1) Flush tank, hoses, boom, and nozzles with clean water. 
2) Prepare a cleaning solution of one gal. of household ammonia per 50 gal. of water. Many 
commercial spray tank cleaners may be used as well. Consult your Winfield Solutions, LLC 
representative for a partial listing of approved tank cleaners and more information about proper 
tank cleaning procedures. Do not use chlorine-based cleaners. 
3) When available, 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. 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 . All visible deposits must be removed from the 
spraying system. 
4) Flush hoses, spray lines, and nozzles for at least one minute with the cleaning solution. 
5) Dispose of rinsate from steps 1 - 3 as described under the Environmental Hazards section of 
the Precautionary Statements. 
6) Repeat steps 2 - 5. 
7) Remove nozzles, screens, and strainers and clean separately in the ammonia cleaning solution 
after completing the above procedures. 
8) Rinse the complete spraying system with clean water. 
 
Impregnation Onto Dry Bulk Granular Fertilizers 
Many dry bulk granular fertilizers may be impregnated or coated with AGH19016 and used to control weeds. 
When applying AGH19016 with dry bulk fertilizers, follow all directions for use, restrictions and precautions

Page 10 of 21 
 
on the AGH19016 label regarding target crops, rates per acre, soil texture, application methods, and 
rotational crops. 
 
Complying with all individual state regulations relating to dry bulk granular fertilizer blending, registration, 
labeling, and application is the responsibility of the individual and/or company selling the herbicide/fertilizer 
mixture. 
 
Prepare the herbicide/fertilizer mixture by using any closed drum, belt, ribbon, or other commonly used dry 
bulk fertilizer blender. Nozzles used to spray AGH19016 onto the fertilizer must be spaced to provide 
uniform spray coverage. Take care to aim the spray onto the fertilizer only, avoiding the walls of the blender. 
 
If the herbicide/fertilizer mixture is too wet, add a highly absorptive material, such as granular clay or 
diatomaceous earth materials, to obtain a dry, free-flowing mixture. Add absorptive materials only after the 
herbicide has been thoroughly blended into the fertilizer mixture. Best application results will be obtained 
by using a granule of 6/30 particle size or of a size similar to that of the fertilizer materials being used. 
Generally, less than 2% by weight of absorptive material will be needed. Avoid using more than 5% 
absorptive material by weight. 
 
Calculate the amount of AGH19016 to be used by the following formula: 
 
2,000 X pt. of AGH19016 per acre = pt. of AGH19016 per ton of fertilizer lbs. of fertilizer per acre 
 
Pneumatic (Compressed Air) Application 
High humidity, high urea concentrations, low fertilizer use rates, and dusty fertilizer may cause fertilizer 
mixtures to build up or plug the distributor head, air tubes, or nozzle deflector plates. To minimize buildup, 
premix AGH19016 with Aromatic 200 at a rate of 2. 0 - 2.5 pt./gal. of AGH19016. Aromatic 200 is a 
noncombustible/nonflammable petroleum product. Aromatic 200 may be used in either a fertilizer blender 
or through direct injection systems. Do not use drying agents when using Aromatic 200. 
 
Mixtures of AGH19016 and Aromatic 200 must be used on dry fertilizer only. Poor results or crop injury 
may result if these mixtures are used in water or liquid fertilizer solutions for spraying applications. When 
impregnating AGH19016 in a blender before application, a drier mixture can be obtained by substituting a 
drying agent for Aromatic 200. The use of a drying agent of 6/30 particle size is recommended. Drying 
agents are not advised for use with On-The-Go impregnation equipment. 
Restrictions: To avoid potential for explosion, 
1) Do not impregnate AGH19016 on ammonium ni trate, potassium nitrate, or sodium 
nitrate, either alone or in blends with other fertilizers. 
2) Do not combine AGH19016 with a single superphosphate (1-20-0) or triple 
superphosphate (0-46-0). 
3) Do not use AGH19016 on straight limestone, since absorption will not be achieved. 
Fertilizer blends containing limestone can be impregnated. 
 
Application of Impregnated Dry Bulk Granular Fertilizer 
Apply 200 - 700 lb. of the herbicide/fertilizer mixture per acre. For best results, apply the mixture 
uniformly to the soil with properly calibrated equipment immediately after blending. Uniform application of 
the herbicide/fertilizer mixture is essential in order to prevent possible crop injury to subsequent rotational 
crops. Non-uniform application may also result in unsatisfactory weed control. In areas where 
conventional tillage is practiced, a shallow incorporation of the mixture into the soil is advised to obtain 
satisfactory weed control. On fine- or medium-textured soils in areas where soil incorporation is not 
planned, i.e., reduced-tillage situations or in some conventional till situations, make applications 
approximately 30 days before planting to allow moisture to move the herbicide/fertilizer mixture into the 
soil. On coarse-textured soils, make applications approximately 14 days prior to planting.

Page 11 of 21 
 
Precaution: To help avoid rotational crop injury, make applications as early as possible, since AGH19016 
impregnated onto dry bulk fertilizers can be expected to last longer in the soil than AGH19016 applied as 
a spray in water or fluid fertilizer.

2 Crop rotation restrictions do not include restrictions for the tank mix partner. Refer to the label of the 
other product for additional restrictions. 
3 Refer to the specific crop use sections for additional crop rotation precautions. 
4 Do not rotate rice after any application to a primary crop at greater than 1.0 lb. a.i. per acre of metribuzin 
per season. 
 
Replanting 
If replanting is necessary in fields previously treated with AGH19016, the field may be replanted to 
soybeans or potatoes. Before replanting, refer to the specific crop use sections for precautions and 
restrictions. 
 
Activation 
A small amount of rainfall or irrigation is required to activate AGH19016 following application. In areas of 
low rainfall, follow a preemergence application with light irrigation of ¼ to ½ inch of water. Do not apply 
heavy irrigation immediately after application. As with many surface-applied herbicides, weed control and 
crop tolerance may vary with rainfall and/or soil texture. 
 
Weed Resistance Management 
AGH19016 contains both a Group 15 herbicide (S-metolachlor) and a Group 5 herbicide (Metribuzin). Any 
weed population may contain plants naturally resistant to Group 15 and/or Group 5 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: 
x Rotate the use of this product or other Group 15 and Group 5 herbicides within a growing season 
sequence or among growing seasons with different herbicide groups that control the same weeds in 
a field. 
x 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 to resistance.

Page 12 of 21 
 
x 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 management practices. 
x Fields should be scouted prior to application to identify the weed species present and their growth 
stage to determine if the intended application will be effective. 
x Scout fields after herbicide application to monito r weed populations for early signs of resistance 
development. Indicators of possible herbicide resistance include: 
o Failure to control a weed species normally controlled by the herbicide at the dose applied, 
especially if control is achieved on adjacent weeds. 
o A spreading patch of non-controlled plants of a particular weed species. 
o Surviving plants mixed with controlled individuals of the same species. 
If resistance is suspected, prevent 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 clean seed. 
x 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. 
x Contact your local extension specialist, certified crop advisors, and/or Winfield Solutions, LLC 
representative for pesticide resistance management and/or integrated weed management 
recommendations for specific crops and resistant weed biotypes. 
x For further information or to report suspected resistance, contact your Winfield Solutions, LLC 
representative.

CROPS 
 
POTATOES (EXCEPT CALIFORNIA) 
AGH19016 may be used for preemergence weed control prior to or after potato emergence. AGH19016 
has some postemergence activity on weeds, but the co nsistency and spectrum of weed control is much 
better preemergence to weeds. There is an increased risk of crop injury with preplant incorporated 
applications. 
The application rates for AGH19016 for use in potatoes are provided below (Table 3 and Table 4). When 
a rate range is given, use the lower rate within the range on the more coarse-textured soils listed within 
that group and/or where weed pressures are known to be light; use the high end of the rate range on the 
more fine-textured soils listed within that group and/or where the weeds pressures are known to be heavy. 
 
See Table 2 for a listing of weeds controlled/suppressed by AGH19016. 
 
Restrictions: 
1) Do not apply more than two treatments per year. 
2) For potatoes grown in soils with organic matter between 3% and 10% do not apply more than 
5.1 pints (3.35 lbs. a.i. S-metolachlor; 0.80 lb. a.i. metribuzin) per acre/year. 
3) For potatoes grown in soils with organic matter between 0.5% and 3.0% do not apply more 
than 4.95 pints (3.25 lbs. a.i. S-metolachlor; 0.77 lb. a.i. metribuzin) per acre/year. 
4) Do not apply AGH19016 to muck or peat soils. 
5) Do not apply more than 1.0 lb. a.i. of metribuzin per acre/year from any source. 
6) Pre-harvest Interval (PHI): Do not harvest within 60 days of the last AGH19016 application. 
7) Do not apply after June 30 in Idaho, Oregon, or Washington if the treated land will be planted 
to a crop other than potatoes in the fall.

Page 14 of 21 
 
8) Do not apply AGH19016 to sweet potatoes or yams. 
 
Precautions: 
1) To avoid crop injury, make postemergence applications only on russetted or white skinned varieties 
of potatoes that are not early maturing. Avoid postemergence applications on Atlantic, Bellchip, 
Centennial, Chipbelle, Shepody and Superior varieties. Preemergence applications on these 
varieties may cause crop injury under adverse weather conditions, on coarse soils, under high soil 
pH and with higher use rates. 
2) Potato varieties may vary in their response to a given herbicide application. When using AGH19016 
for the first time on a particular variety, always determine crop tolerance before using on a field-scale. 
3) The planting of sensitive crops such as lettuce, cole crops and cucurbits during the next growing 
season following application of AGH19016 may result in injury to that crop. 
4) Certain cereal varieties are sensitive to metribuzin an d are not advised to be planted during the next 
growing season unless the following cultural practices occur: 
a) Potato vines left in the row as a result of harvest must be uniformly distributed over the soil 
surface prior to plowing, and 
b) Plow with a moldboard plow to a depth sufficient to mix the upper 8 inches of soil. 
5) Crop injury may occur if AGH19016 is applied as a preplant incorporated application in potatoes. 
6) Applying AGH19016 postemergent when the weather in the next 3 days is predicted to be cool, wet 
or cloudy, may cause crop injury. 
 
Preemergence Applications 
Apply with ground spray equipment, aerial spray equipment, or by center pivot irrigation equipment which 
is capable of making a uniform broadcast application. Apply after planting but before crop emergence, or 
apply after drag-off if this operation is part of the usual cultural practice.

Tank Mixtures With Other Products Registered for Use in Potatoes 
For preemergence applications in potatoes, AGH19016 ma y be tank mixed with other pesticide products 
registered for use in this way and timing in potatoes. 
 
For postemergence applications (center pivot irrigation applications only), i.e. where potato vines are 
exposed, there may be increased risk of crop injury from certain product mixtures. At this application timing, 
tank mix AGH19016 only with pesticide products which allow tank mixing and postemergence chemigation 
on their product label. 
 
See the Tank Mix section on this label for further information on tank mixing. 
 
SOYBEANS (EXCEPT CALIFORNIA) 
AGH19016 may be applied preplant surface, preplant incorporated, preemergence, as a sequential 
application, or as a postemergence directed (see state limitations) to control weeds listed on this label. 
See Table 2 for a listing of weeds controlled/suppressed by AGH19016. 
 
Grazing and Feeding Treated Soybean Plants 
Do not graze or feed soybean plants to livestock if they have received a post-emergent (directed application) 
treatment. For other applications, treated soybean plants may be grazed or fed to livestock 40 days after 
the last application of AGH19016. 
 
Rate Ranges 
Where a rate range is shown, use the lower rate on soils that are coarse-textured and/or low in organic 
matter. Use the higher rate on soils that are relatively fine-textured and/or high in organic matter. 
 
Replanting 
If replanting is necessary in fields previously tr eated with AGH19016, the field may be replanted to 
soybeans. Minimum tillage is advised. E xcessive tillage will reduce residual weed control. Do not apply a 
second treatment as injury to soybeans may occur. 
 
Precautions 
Injury to soybeans or reduced weed control may occur when AGH19016 is used under the following 
conditions. Avoid these conditions wherever possible. 
1) When soils have a calcareous surface area or a pH of 7.5 or higher. 
2) Due to the sensitivity of certain soybean varieties, do not apply AGH19016 on varieties that 
are not confirmed as being tolerant to metribuzin. Consult the seed supplier for information on 
its tolerance to metribuzin (an active ingredient in AGH19016) before using AGH19016. 
3) When applied in conjunction with soil-applied organic phosphate pesticides. 
4) Uneven application or improper incorporation of AGH19016 can decrease the level of weed 
control and/or increase the level of crop injury. 
5) When applied to any soil with less than 0.5% organic matter. 
6) Where soil incorporation is deeper than recommended. 
7) When sprayers were not calibrated accurately. 
8) When heavy rains occur soon after application, especially in poorly drained areas where water 
may stand for several days. 
9) When soybeans are planted less than 1½” deep, particularly when AGH19016 is applied 
preemergence. 
10) Where high soil levels of atrazine are present. 
11) When using poor quality soybean seed. 
 
Restriction: Do not exceed 3.71 lbs. a.i. per acre per year of S-metolachlor containing products.

Page 16 of 21 
 
 Tank Mixing 
AGH19016 may be tank mixed with other products at appropriate rates as long as tank mixing is not 
prohibited by the label(s) of the tank mix partner products, or as otherwise noted within the soybean section 
of this label and the tank mix partner products are labeled for the timing and method of application. 
 
See the Tank Mix section on this label for further information on tank mixing. 
 
AGH19016 Foundation Program for a Planned 2-Pass Weed Control Systems (preplant incorporated 
or preemergence application followed by other herbicide) 
AGH19016 may be applied preplant incorporated or preemergence at 1.5 - 1.8 pt./A on all soils to reduce 
competition from the weeds listed in Table 2 for a 30-day period when followed by a planned 
postemergence weed control treatment. On soils with pH above 7.0, use the 1.5 pt./A rate only. 
Recommended postemergence treatments include any product or combination of products labeled to 
control the specific weeds remaining in the field, including glyphosate products (for use only on glyphosate 
tolerant soybean varieties). Follow all application directions for AGH19016 used alone, either preplant 
incorporated or preemergence. For the postemergence herbicide application, consult the selected 
postemergence herbicide manufacturer’s label for weeds controlled, weed size, application rate, additional 
use directions, precautions, and limitations before use. See the Tank Mix section on this label for further 
information on tank mixing. 
 
AGH19016 in Conventional Tillage Systems 
Preplant Incorporated Application: Incorporate AGH19016 uniformly into the top 2 inches of soil within 
14 days before planting using a disk, field cultivator, rolling cultivator, or similar implement. Apply 
AGH19016 preplant incorporated if furrow irrigation is used or when a period of dry weather after 
application is expected. If soybeans are planted on beds, apply and incorporate the tank mixture after bed 
formation. 
Preemergence Application: Dry weather following preemergence application of AGH19016 may reduce 
effectiveness. If weeds develop, cultivate uniformly with shallow tilling equipment such as a rotary hoe that 
will not damage soybeans. 
For information on applying product in fluid or dry fertilizer, refer to Application in Water or Fluid 
Fertilizers or Impregnation Onto Dry Bulk Granular Fertilizers and Application of Impregnated Dry 
Bulk Granular Fertilizer on this label.

2 Use the higher rate under heavy weed pressures and/or on soils higher in organic matter. For maximum 
 control of sicklepod, use a preemergence application. 
 
Precaution: On soils with pH above 7.0, soybean injury caused by the metribuzin in AGH19016 may occur 
at rates higher than 1.5 pt./A. To avoid injury, do not use AGH19016 at rates greater than 1.5 pt./A on soils 
above pH 7.0. 
 
Burndown Weed Control 
AGH19016 can be used as part of a burndown herbicide program for control of existing vegetation prior to 
soybean emergence in conservation tillage (reduced- tillage/no-till) systems. 
 
AGH19016 may be tank mixed with other herbicides registered for the same use and timing for control of 
emerged weeds prior to crop emergence. Apply AGH19016 burndown tank mixes before planting or prior 
to crop emergence. See the Tank Mix section on this label for further information on tank mixing. 
 
Application 
AGH19016 may be applied up to 30 days before planting or preemergence. Apply only by ground 
equipment when AGH19016 is used for burndown of existi ng vegetation in conservation tillage systems. 
Use the high end of the rate range for AGH19016 applications made 14 - 30 days before planting. Refer to 
Table 7 for rates of AGH19016. Refer to the tank mix product labels for rates and use directions. Follow all 
label directions, restrictions, and precautions for tank mix partners. Where differences arise, the more 
restrictive language must be followed. 
 
Refer to the Product Information section of this label for additional information, precautions, and 
limitations. 
 
Restrictions for Burndown Weed Control in Soybeans: 
1) Do not apply these treatments after crop emergence. 
2) Burndown application may only be made by ground. 
3) Soybean plants or hay treated with AGH19016 as a burndown treatment may be grazed or fed to 
livestock 40 days after application. Follow the most restrictive preharvest interval of all products used 
in a tank mixture. 
 
AGH19016 Use Rates For Reduced and No-Till Systems 
 
Preplant Surface Application 
AGH19016 may be used in reduced-till and no-till systems. Applications may be made up to 30 days before 
planting or after planting, but before soybean emergence. 
 
Residual herbicides may be tank mixed for additional weed control. If weeds are present at time of 
application, burndown herbicides may be added to the tank mixes (see Burndown Weed Control section). 
Refer to the tank mix product labels for rates and use directions. See the Tank Mix section on this label for 
further information on tank mixing.

2 Do not use on sand soils. On coarse-textured soils, do not use on loamy sand soils with less than 2% 
organic matter. 
3 Silty clay loam soils are transitional soils and may be classified as medium-textured soils in some regions 
of the U.S. When using AGH19016, treat this soil as “fine-textured.” 
 
AGH19016 Sequential Application 
An early preplant (surface-applied or shallow incorporated) application of AGH19016, followed by a 
preemergence application of AGH19016 after planting but before soybean emergence, will provide more 
consistent control of broadleaf and grass weeds than a single application. 
 
A sequential application will decrease the need for tillage and/or burndown herbicides for the control of 
existing vegetation before planting, while providing residual control of weeds after planting. 
 
Application 
An early preplant application may be made 15 - 30 days before planting soybeans. Follow this application 
with a preemergence overlay application of AGH19016 after planting but before crop emergence. Follow 
directions on this label for sequential applications from 0 - 14 days before planting. 
 
Where a rate range is listed, use the higher rates (a) in fields with a history of severe weed pressure, (b) 
when the time between early preplant and preemergence overlay applications approaches the maximum 
30 days, (c) when the organic matter content of the soil is over 3%, and/or (d) when heavy crop residues 
are present on the soil surface. 
When weeds exceed 1 - 1.5 inches in height or diameter at application, use a burndown herbicide, such 
as glyphosate, paraquat, or 2,4-D LVE. 
Weeds Controlled: In addition to weeds controlled by AGH19016 alone, the sequential application 
improves control of the following annual broadleaf weeds: buffalobur, cocklebur, common ragweed, 
velvetleaf, and sunflower.

with less than 2% organic matter, or on loamy sand or sandy loam soils with less than 1% organic 
matter. 
2 Silty clay loam soils are transitional soils and may be classified as medium-textured soils in some 
regions of the U.S. When using AGH19016, treat this soil as “fine-textured.” 
 
Restriction: Do not to exceed 3.9 pints (2.56 lbs. a.i. S-metolachlor; 0.61 lb. a.i. Metribuzin) of AGH19016 
per acre per year. 
 
Postemergence Directed Application (AR, LA, MO – Bootheel only, MS, TN) 
AGH19016 can be applied postemergence directed to soybeans to provide residual control of weeds that 
emerge after crop emergence in the states of Arkansas , Louisiana, Missouri - Bootheel only, Mississippi 
and Tennessee. A postemergence directed spray of AGH19016 can be applied to soybeans in addition to 
a preemergence or preplant application of AGH19016 according to label directions. The total amount of 
AGH19016 applied must not exceed 3.9 pints per acre per year. 
See Table 9 below for AGH19016 postemergence directed rates according to soil type and organic matter 
level.

A postemergence directed application of AGH19016 will provide residual preemergence weed control of 
the weeds listed in Table 2. 
 
Apply in 10 to 20 gallons of water per acre in a 6 to 8 inch band on each side of the row when soybeans 
are at least 8 inches tall. Do not allow the directed spray to contact more than the lower ¼ to ѿ of soybean 
plants. Soybean leaves contacted by the spray will be killed or severely injured. Do not apply directly to 
soybeans or serious injury will occur. 
 
Precaution: If heavy rain occurs soon after application, crop injury may result, especially in poorly drained 
areas where water stands for several days. 
 
Post-Directed Application Tank Mixes - Glyphosate Tolerant Soybeans Only 
Postemergence directed applications of AGH19016 can be tank mixed with glyphosate in glyphosate-
tolerant soybeans only. See the Tank Mix section on this label for further information on tank mixing. 
 
Postemergence Directed Applications – Restrictions 
1) Do not exceed a total of 3.9 pints (2.56 lbs. a.i. S-metolachlor; 0.61 lb. a.i. Metribuzin) per acre per 
year of AGH19016. 
2) Do not exceed 3.71 lbs. a.i. per acre per year of S-metolachlor containing products. 
3) Do not graze or feed treated soybean forage, hay, or straw to livestock. 
4) Pre-harvest Interval (PHI): Do not apply within 75 days of soybean harvest. 
5) Do not apply AGH19016 to sandy loam or loamy sand soils with less than 2% organic matter.
