areas below the mean high-water mark. Do not contaminate water when cleaning 
equipment or disposing of equipment washwater or rinsate. Apply this product only as 
directed on the label. 
 
2.3.1 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. 
Dicamba 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.

2.3.2 Surface Water Advisory 
One of the active ingredients in SAN837 CORN HERBICIDE PLUS VAPORGRIP 
TECHNOLOGY, S-metolachlor, 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 avoiding 
applications when rainfall or irrigation is expected to occur within 48 hours. 
2.3.3 NON-TARGET ORGANISM ADVISORY 
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.

3.0 PRODUCT INFORMATION 
SAN837 CORN HERBICIDE PLUS VAPORGRIP TECHNOLOGY is a foliar systemic 
broadleaf herbicide with residual control of grass and certain broadleaf weeds in: 
• Field corn 
• Fallow Cropland (postharvest, crop stubble, or set-aside) 
 
This product needs a minimum of ½ inch of either rainfall or irrigation following 
application to activate residual weed control. If rainfall or irrigation is not received within 
10 days after application, residual weed control may be reduced. Under these 
conditions, cultivate or use other weed control measures if weeds develop. 
Rainfall or irrigation occurring within 4 hours after postemergence application may 
reduce effectiveness.

3.1 Weed Resistance Management Practices 
DICAMBA GROUP 4 HERBICIDE 
S-METOLACHLOR GROUP 15 HERBICIDE 
 
For resistance management, please note that SAN837 CORN HERBICIDE PLUS 
VAPORGRIP TECHNOLOGY contains both a Group 4/dicamba and a Group 15/S-
metolachlor herbicide. Any weed population may contain plants naturally resistant to 
Group 4 and/or Group 15 herbicides. The resistant individuals may dominate the weed 
population if these herbicides are used repeatedly in the same fields. Appropriate 
resistance-management strategies should be followed. 
Contact your local Syngenta representative, retailer, crop advisor or extension agent to 
determine if weeds resistant to modes of action contained in this product are present in 
your area. Do not assume that each listed weed is being controlled by multiple modes 
of action. Premixes are intended to broaden the spectrum of weeds that are controlled. 
Some weeds may be controlled by only one of the active ingredients in this product. If 
resistant biotypes have been reported, use the full labeled rate of this product, apply at 
the labeled timing, and tank-mix with an additional different mode of action product so 
there are multiple effective modes of application for each suspected resistant weed. 
3.1.1 Principles of Herbicide Resistant Weed Management 
Scout and know your field 
• Know weed species present in the field to be treated through scouting and field 
history. An understanding of weed biology is useful in designing a resistance 
management strategy. Ensure the weed management program will control all 
weeds present. 
• Fields should be scouted prior to application to determine species present and 
growth stage. Always apply this herbicide at the full labeled rate and correct 
timing for the weeds present in the field. 
Utilize non-herbicidal practices to add diversity 
• Use diversified management tactics such as cover crops, mechanical weed 
control, harvest weed seed control, and crop rotation as appropriate. 
Use good agronomic practices, start clean and stay clean 
• Use good agronomic practices that enhance crop competitiveness. 
• Plant into weed-free fields utilizing tillage or an effective burndown herbicide for 
control of emerged weeds. 
• Sanitize farm equipment to avoid spreading seed or vegetative propagules prior 
to leaving fields.

Difficult to control weeds 
• Fields with difficult to control weeds should be planted in rotation with crops that 
allow the use of herbicides with an alternative mode of action or different 
management practices. 
• Difficult to control weeds may require sequential applications, such as a broad 
spectrum preemergence herbicide followed by one or more postemergence 
herbicide applications. Utilize herbicides containing different modes of action 
effective on the target weeds in sequential applications. 
Do not overuse the technology 
• Do not use more than two applications of this or any other herbicide with the 
same mode of action in a single growing season unless mixed with an herbicide 
with a different mode of action which provides overlapping spectrum for the 
difficult to control weeds. 
Scout and inspect fields following application 
• Prevent an influx of weeds into the field by controlling weeds in field borders. 
• Scout fields after application to verify that the treatment was effective. 
 
• Suspected herbicide resistant weeds may be identified by these indicators: 
• Failure to control a weed species normally controlled by the herbicide at 
the dose applied, especially if control is achieved on adjacent weeds; 
• A spreading patch of non-controlled plants of a particular weed species; 
and 
• Surviving plants mixed with controlled individuals of the same species. 
• Report non-performance of this product to your Syngenta retailer, Syngenta 
representative, or call 1-866-Syngent(a) (866-796-4368). If resistance is 
suspected, ensure weed escapes are controlled using an herbicide with an 
effective mode of action and/or use non-chemical means to prevent further seed 
production. 
Prevent weed escapes before, during, and after harvest 
Do not allow weed escapes to produce seed or vegetative structures such as tubers or 
stolons which contribute to spread and survival. Consider harvest weed seed 
management and control weeds post-harvest to prevent seed production. 
4.0 APPLICATION DIRECTIONS 
4.1 Methods of Application 
 
Applications with SAN837 CORN HERBICIDE PLUS VAPORGRIP TECHNOLOGY 
alone or in tank mixtures are permitted with ground equipment only. Preplant, at-

planting, preemergence and post harvest applications are allowed as specified in 
Section 9.0 unless otherwise restricted in Section 7.1. 
 
4.2 Application Equipment 
 
• Configure spray equipment to provide accurate and uniform coverage of the target 
area and minimize potential for spray drift. 
• To ensure accuracy, calibrate sprayer before each use. For information on spray 
equipment and calibration, consult spray equipment manufacturers and/or state 
recommendations. 
• Only use sprayers that provide accurate and uniform application with nozzles 
designed to produce extremely coarse to ultra-coarse droplets in order to 
minimize drift (Section 7.3.1) and provide uniform coverage. 
• Avoid using screens and strainers finer than 50-mesh. 
• All ground application equipment must be properly maintained. 
• All equipment must be washed to remove product residues after use (Section 4.6). 
 
4.3 Application Volume and Spray Coverage 
• For ground application, apply alone or in tank mixtures in a minimum of 15 gal/A of 
spray solution. 
• Good spray coverage of emerged weeds is essential for optimum control. 
• When weed vegetation is dense, increase spray volume and pressures to ensure 
coverage of the target weeds. 
• Spray boom and nozzle heights must be adjusted to provide coverage of target 
weeds but not more than 24 inches above the target. 
 
4.4 Equipment Ground Speed 
Select a ground speed that will deliver the desired spray volume while maintaining the 
desired spray pressure, but slower speeds generally result in better spray coverage and 
deposition on the target area. 
 
4.5 Mixing Directions 
1. SAN837 CORN HERBICIDE PLUS VAPORGRIP TECHNOLOGY may be tank-
mixed or applied sequentially with other products. 
2. Thoroughly clean spray equipment before using this product (Section 4.6). Dispose 
of the cleaning solution in a responsible manner. 
3. Prepare no more spray mixture than is needed for the immediate operation. 
4. Flush the spray equipment thoroughly following each use and apply the rinsate to a 
previously treated area. 
5. Pesticide, spray mixture, or rinsate that cannot be used according to label 
instructions must be disposed of according to federal, state, or local procedures. For

guidance in proper disposal methods, contact your State Pesticide or Environmental 
Control Agency, or the Hazardous Waste representative at the nearest EPA 
Regional Office. 
 
4.5.1 SAN837 CORN HERBICIDE PLUS VAPORGRIP 
TECHNOLOGY Alone 
1. Fill the spray tank ½ to ⅔ full with clean water. 
2. Begin tank agitation and continue throughout mixing and spraying. 
3. Add SAN837 CORN HERBICIDE PLUS VAPORGRIP TECHNOLOGY. 
4. Add spray additives. 
5. Fill the remainder of spray tank. 
6. The tank mixture should be sprayed out as soon as it is prepared. 
 
4.5.2 Tank-Mix Precautions 
• Observe all precautions, directions for use and restrictions on the labels of each 
product used in tank mixtures. 
• Follow the most restrictive label precautions and limitations. 
• 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. 
• Tank mixes with other pesticides, fertilizers, or any other additives not specifically 
labeled for use with SAN837 CORN HERBICIDE PLUS VAPORGRIP 
TECHNOLOGY may result in tank mix incompatibility or unsatisfactory performance. 
In such cases, always check tank mix compatibility by conducting a jar test 
according to guidance in Section 4.5.3 before actual tank mixing. 
 
4.5.3 Tank-Mix Compatibility Test 
• Conduct a jar test using a 1 pt to 1 qt container with lid by adding water or other 
intended carrier such as a liquid fertilizer to the jar. 
• Next, add the appropriate amount of pesticide(s) or tank-mix partner(s) in their 
relative proportions based on label rates. Add tank-mix components separately in 
the order described in the tank-mixing section, Section 4.5.4. After each addition, 
shake or stir gently to thoroughly mix. 
• After all ingredients have been added, put the lid on the jar, tighten and invert the jar 
10 times to mix. 
• After mixing, let the mixture stand 15 – 30 minutes and then examine for signs of 
incompatibility such as obvious separation, large flakes, precipitates, gels or heavy 
oily film on the jar. 
• If the mixture remains mixed or can be remixed readily, it is physically compatible 
and can be used.

• If the mixture is incompatible, repeat the test using a compatibility agent at the label 
rate. Or, if applicable, slurry dry formulations in water before adding to the jar. If 
incompatibility is still observed after following these procedures, do not use the 
mixture. 
• After compatibility testing is complete, dispose of any pesticide wastes in 
accordance with the storage and disposal section, Section 10.0, of this label.

instructions for the crop of interest. 
 
4.6 Sprayer Cleanout 
Severe crop injury may occur if any of this product remains in the spray system 
equipment following an application and the equipment is subsequently used for 
application to sensitive crops. After using this product, clean all mixing and spray 
equipment (including tanks, pumps, lines, filters, screens, and nozzles) with a strong 
detergent based sprayer cleaner. The rinsate must be disposed in compliance with 
local, state, and federal guidelines. 
Inadvertent contamination can also occur in equipment used for bulk product handling 
and mixing prior to use in the spray system. Care should be taken to reduce 
contamination not only in the spray system but in any equipment used to transfer or 
deliver product. For example, bulk handling and mixing equipment containing this 
product should be segregated when possible to reduce potential for cross-
contamination. Consider using block and check valves to avoid backflow during transfer.

Piping should be reviewed to ensure there is not potential for product build-up. 
Dedicated nurse trucks and tender equipment should be used when possible. 
To avoid subsequent injury to other crops, thoroughly clean mixing and application 
equipment immediately after spraying. The following instructions are provided: 
 
1. Do not clean sprayer near desirable vegetation, wells or other water sources. 
2. Drain and flush tank walls, boom and all hoses with clean water. 
3. Prepare a cleaning solution with a detergent or a commercial sprayer cleaner or 
ammonia according to the product’s use directions.

6.0 COVER CROPS 
A cover crop can be an important tool for the overall farm cropping system. Cover 
crops are planted for conservation purposes, soil erosion control, soil health 
improvement, water quality improvement and weed management. A cover crop can be 
a single crop or a combination of crops, including grasses and/or broadleaf crops. 
After harvest of a SAN837 CORN HERBICIDE PLUS VAPORGRIP TECHNOLOGY 
treated crop, planting of a cover crop is allowed, provided the cover crop is not grazed 
or fed to livestock nor harvested for food. Terminate the cover crop through natural 
causes, such as frost or intentional termination by herbicide application, crimping, 
rolling, tillage or cutting. 
All possible cover crops or cover crop combinations have not been tested for tolerance 
to this product. Before planting the cover crop, determine the level of tolerance for the 
intended cover crops by conducting a field bioassay. Refer to Section 6.1 for 
instructions on how to conduct a field bioassay.

6.1 Field Bioassay for Cover Crops 
A field bioassay is a method of determining if herbicide residues are present in the soil 
at concentrations high enough to adversely affect crop growth. 
 
Conduct the field bioassay by planting several strips of the desired cover crop across 
the field which has been previously treated with SAN837 CORN HERBICIDE PLUS 
VAPORGRIP TECHNOLOGY. Plant the cover crop strips perpendicular to the direction 
of the product application. Locate the strips so that all the different field conditions are 
encountered, including differences in field terrain, soil texture, organic matter, pH, and 
drainage. 
 
If the cover crop does not show adverse effects such as crop injury and/or stand 
reduction, the field can be planted to this cover crop. If injury and/or stand reduction are 
visible, wait two to four weeks for further herbicide degradation to occur and repeat the 
bioassay. Alternatively, select a different cover crop and repeat the bioassay. Only 
plant cover crops that show acceptable tolerance in the field bioassay.

• 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. 
 
7.2 Use Precautions 
• SAN837 CORN HERBICIDE PLUS VAPORGRIP TECHNOLOGY requires actively 
growing green plant tissue to function fully for postemergence weed control. 
Application to drought-stressed weeds or weeds with little green foliage (i.e., mowed, 
cut, or hailed on weeds); weeds covered with dust; weeds damaged by insects or 
diseases may result in reduced weed control. 
• Drift may cause damage to non-target vegetation. 
• Avoid spray overlap, as crop injury may result. 
• Before planting a cover crop, determine the level of tolerance for the intended cover 
crop to SAN837 CORN HERBICIDE PLUS VAPORGRIP TECHNOLOGY by 
conducting a field bioassay (Section 6.1). 
• Thoroughly clean the spray system using either a solution of water/strong detergent 
or a commercially available tank cleaner after each use (Section 4.6). 
 
7.3 Mandatory Spray Drift Management 
 
Ground Boom Applications: 
• User must only apply with the release height recommended by the 
manufacturer, but no more than 24 inches above the ground or crop canopy. 
• Applicators are required to use only nozzles producing extremely coarse to 
ultra-coarse droplets (ASABE S572). 
• DO NOT apply during temperature inversions. 
• DO NOT apply when the wind speed is less than 3 mph or greater than 10 
mph. 
• DO NOT apply when weather conditions may cause drift to nontarget areas. 
 
Boomless Ground Applications: 
• Applicators are required to use only nozzles producing extremely coarse to 
ultra-coarse droplets (ASABE S572) for all applications. 
• DO NOT apply when the wind speed is less than 3 mph or greater than 10 
mph. 
• 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. The interaction of many equipment- and weather-related factors 
determines the potential for spray drift. The applicator is responsible for considering 
these factors when making a decision. 
 
7.3.1 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. Use only nozzles producing extremely 
coarse to ultra-coarse droplets as defined by the American Society of Agricultural 
and Biological Engineers (ASABE) S-572.2. 
• 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. 
 
7.3.2 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 not less than 15 gallons 
per acre for the application. If a greater spray volume is needed, consider using a 
nozzle with a higher flow rate. 
• Pressure – Use the lowest spray pressure recommended for the nozzle to produce 
the target spray volume and droplet size. DO NOT exceed the nozzle manufacturer’s 
specified pressures or maximum pressures. For many nozzle types, lower pressure 
produces larger droplets. When higher flow rates are needed, use higher flow rate 
nozzles instead of increasing pressure. If sprayer is equipped with rate controller 
hardware, ensure it does not allow pressure increases that exceed the desired 
range. 
• Spray nozzles – Use a spray nozzle that is designed for the intended application. 
Consider using nozzles designed to reduce drift. 
 
7.3.3 BOOM HEIGHT – Ground Boom 
• For ground equipment, the boom should remain level with the crop and have 
minimal bounce. Use manufacturer's recommendation for boom height or 24 inches 
above the crop height, whichever is smaller. Excessive boom height will increase the 
drift potential. 
7.3.4 Wind 
• Drift potential generally increases with wind speed. AVOID APPLICATIONS 
DURING GUSTY WIND CONDITIONS. Drift potential is lowest when wind speeds 
are 3 to 10 mph. DO NOT apply this product when the wind speed is less than 3 
mph or greater than 10 mph. Applicators need to be familiar with local wind patterns 
and terrain that could affect spray drift.

7.3.5 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. 
 
7.3.6 Temperature and Humidity 
When making applications in low relative humidity or temperatures above 91°F, set up 
equipment to produce larger droplets to compensate for evaporation. Larger droplets 
have a lower surface to volume ratio and can be impacted less by temperature and 
humidity. Droplet evaporation is most severe when conditions are both hot and dry. 
7.3.7 Temperature Inversions 
• Drift potential is high during a temperature inversion. DO NOT apply during a 
temperature inversion. 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 
concentrated cloud (under low wind conditions) indicates an inversion, while smoke 
that moves upward and rapidly dissipates indicates good vertical air mixing. 
• The inversion will typically dissipate with increased winds (above 3 miles per hour) 
or at sunrise when the surface air begins to warm (generally 3°F from morning low). 
 
7.3.8 Sensitive Areas 
• DO NOT apply under circumstances where spray drift may occur to food, 
forage, or other plantings that might be damaged or the crops thereof may be 
rendered unfit for sale, use or consumption. 
• Apply SAN837 CORN HERBICIDE PLUS VAPORGRIP TECHNOLOGY only when 
the potential for drift to adjacent sensitive areas (e.g., residential areas, bodies of 
water, known habitat for threatened or endangered species, nontarget crops) is 
minimal (i.e., when wind is blowing away from the sensitive areas). 
• Applicators are required to ensure that they are aware of the proximity to sensitive 
areas to avoid potential adverse effects from off-target movement of SAN837 CORN 
HERBICIDE PLUS VAPORGRIP TECHNOLOGY.

7.3.9 Sensitive Crops 
To protect sensitive crops, the following restrictions must be followed: 
• Before making an application, the applicator must survey the application site for 
adjacent nontarget sensitive crops. 
• DO NOT APPLY this product when the wind is blowing toward adjacent sensitive 
crops. 
• During application and sprayer cleanout, DO NOT allow contact of herbicide with 
foliage, green stems, exposed non-woody roots of crops, and desirable plants. 
 
The applicator must be aware that wind direction may vary during the application. If 
wind direction shifts such that the wind is blowing toward adjacent sensitive crops, the 
applicator must STOP the application. 
 
Crops known to be sensitive include but are not limited to: 
 
• non-dicamba-tolerant soybeans and cotton 
• EPA Crop Group 6 (peas and beans) 
• EPA Crop Group 8 (fruiting vegetables including peppers and tomatoes) 
• EPA Crop Group 9 (cucurbit group including cucumbers and melons) 
• flowers 
• fruit trees 
• grapes 
• ornamental plantings including broadleaf ornamentals grown in greenhouses and 
shadehouses 
• other broadleaf plants 
• peanuts 
• potatoes 
• sweet potatoes 
• sunflower 
• tobacco 
 
Sensitive Crops may be severely injured or killed if they are contacted by this 
product.
