mean high water mark. DO NOT contaminate water when disposing of equipment washwaters or rinsate.

Nicosulfuron + Rimsulfuron + Dicamba / GF-3967 / Prop Sec 3 / Amend / 03-08-21 Page 7
Groundwater Advisory
This product is known to leach through soil into groundwater under certain conditions as a result of label 
use. This product may leach into groundwater 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 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 months or more after application. A level, well-maintained 
vegetative buffer strip between areas to which this product is applied and surface water features including
ponds, streams, and springs will reduce the potential loading of this product from runoff water and 
sediment. Runoff of this product will be greatly reduced by avoiding applications when rainfall or irrigation 
is expected to occur within 48 hours.
Ground and Surface Water Protection
Point source contamination: To prevent point source contamination, DO NOT mix, load this pesticide 
product within 50 feet of wells (including abandoned wells and drainage wells), sink holes, perennial or 
intermittent streams and rivers, and natural or impounded lakes and reservoirs. DO NOT apply pesticide 
product within 50 feet of wells. This setback does not apply to properly capped or plugged abandoned 
wells and does not apply to impervious pad or properly diked mixing/loading areas as described below. 
Mixing, loading, rinsing, or washing operations performed within 50 feet of a well are allowed only when
conducted on an impervious pad constructed to withstand the weight of the heaviest load that may be on 
or move across the pad. The pad must be self-contained to prevent surface water flow over or from the 
pad. The pad capacity must be maintained at 110% that of the largest pesticide container or application 
equipment used on the pad and have sufficient capacity to contain all product spills, equipment or 
container leaks, equipment wash waters, and rainwater that may fall on the pad. The containment 
capacity does not apply to vehicles delivering pesticide shipments to the mixing/loading site. States may 
have in effect additional requirements regarding wellhead setbacks and operational containment.
Care must be taken when using this product to prevent: a) back siphoning into wells, b) spills or c) 
improper disposal of excess pesticide, spray mixtures or rinsates. Check valves or antisiphoning devices 
must be used on all mixing equipment.
Movement by surface runoff or through soil: DO NOT apply under conditions which favor runoff. DO 
NOT apply to impervious substrates including paved or highly compacted surfaces in areas with high 
potential for ground water contamination. Ground water contamination may occur in areas where soils are 
permeable or coarse and ground water is near the surface. DO NOT apply to soils classified as sand with 
less than 3% organic matter and where ground water depth is shallow. To minimize the possibility of 
ground water contamination, carefully follow application rate specifications as affected by soil type in the 
general information section of this label.
Windblown Soil Particles Advisory
This product has the potential to move off-site due to wind erosion. Soils that are subject to wind erosion 
usually have a high silt and/or fine to very fine sand fractions and low organic matter content. Other 
factors which can affects the movement of windblown soil include the intensity and direction of prevailing 
winds, vegetative cover, site slope, rainfall, and drainage patterns. Avoid applying this product if 
prevailing local conditions may be expected to result in off-site movement.
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 area. Protect the forage and habitat of non-target 
organisms by minimizing spray drift. For further guidance and instructions on how to minimize spray drift, 
refer to the Spray Drift Management section of this label.
Endangered Species Concerns

Nicosulfuron + Rimsulfuron + Dicamba / GF-3967 / Prop Sec 3 / Amend / 03-08-21 Page 8
The use of any pesticide in a manner that may kill or otherwise harm an endangered species or adversely 
modify their habitat is a violation of federal law.
DIRECTIONS FOR USE
It is a violation of federal law to use this product in a manner inconsistent with its labeling.
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. For any requirements specific to your 
State or Tribe, consult the agency responsible for pesticide regulation.
AGRICULTURAL USE REQUIREMENTS
Use this product only in accordance with its labeling and with the Worker Protection Standard, 40 CFR 
part 170. This Standard contains requirements for the protection of agricultural workers on farms, 
forests, nurseries, and greenhouses, and handlers of agricultural pesticides. It contains requirements 
for training, decontamination, notification, and emergency assistance. It also contains specific 
instructions and exceptions pertaining to the statements on this label about personal protective 
equipment (PPE) and restricted-entry interval. The requirements in this box only apply to uses of this 
product that are covered by the Worker Protection Standard.
DO NOT enter or allow worker entry into treated areas during the restricted entry interval (REI) of 24 
hours. Exception: If the product is soil injected or soil incorporated, the Worker Protection Standard, 
under certain circumstances, allows workers to enter the treated areas if there will be no contact with 
anything that has been treated. 
PPE required for early entry to treated areas that is permitted under the Worker Protection Standard 
and that involves contact with anything that has been treated, including plants, soil, or water, is:
x Coveralls worn over short-sleeve shirt and short pants

PRODUCT INFORMATION
GF-3967 is a water-dispersible granule herbicide formulation used for selective postemergence grass and 
broadleaf weed control in field corn.
GF-3967 can be tank mixed with a variety of herbicides to improve burndown and residual control; 
however, the most restrictive label must be followed. Residual weed control is dependent on rainfall or 
sprinkler irrigation for herbicide activation. 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.
BIOLOGICAL ACTIVITY
GF-3967 is absorbed through the shoots and roots of plants, rapidly inhibiting the growth of susceptible 
weeds. Rainfall or sprinkler irrigation is needed to move GF-3967 into the soil. Susceptible weeds will 
generally not emerge from preemergence application. In some cases susceptible weeds may germinate 
and emerge a few days after application, but growth then ceases and leaves become chlorotic three to 
five days after emergence. Death of leaf tissue and growing point will follow in some species, while others 
will remain green but stunted and noncompetitive.

combinations of fallow, preemergence, and postemergence applications GF-3967, as well as rimsulfuron 
from application(s) of other rimsulfuron products.
DO NOT apply GF-3967 when soybeans are growing nearby if any of these conditions exist:
- corn is more than 20” tall
- soybeans are more than 10” tall
- soybeans have begun to bloom
DO NOT apply to field corn grown for seed, to popcorn or to sweet corn.
DO NOT apply aerially in California or New York State.
Injury or loss of desirable trees or vegetation may result from failure to observe the following:
x DO NOT apply GF-3967 or drain or flush application equipment on or near desirable trees or other 
plants, or on areas where their roots may extend, or in locations where the chemical may be washed 
or moved into contract with their roots.
x DO NOT use on lawns, walks, driveways, tennis courts.
x DO NOT contaminate any body of water.
DO NOT apply GF-3967 through any type of irrigation system.
DO NOT graze or feed forage, grain or fodder (stover) from treated areas to livestock within 30 days of 
GF-3967 application. Corn may be harvested or grazed for feed once the crop has reached the ensilage 
(milk) stage or later in maturity.
DO NOT make fallow or preemergence applications to coarse-textured soils (sand, loamy sand, or sandy 
loam) with less than 1% organic matter.
DO NOT treat irrigation ditches or water used for crop irrigation or domestic uses.
DO NOT treat areas where either possible downward movement into the soil, or surface washing, may 
cause contact of GF-3967 with the roots of desirable plants including trees and shrubs.
DO NOT apply to crops under stress due to lack of moisture, hail damage, flooding, herbicide injury, 
mechanical injury, insects, or widely fluctuating temperatures as injury may result.
DO NOT apply GF-3967 tank mixtures with glyphosate herbicides to conventional corn hybrids that DO 
NOT contain the glyphosate-resistance trait.
DO NOT apply GF-3967 tank mixtures with glufosinate herbicides to conventional corn hybrids that DO 
NOT contain the glufosinate-resistance trait.
To avoid crop injury or antagonism, apply the products indicated below at least seven days before or 
three days after the application of GF-3967.
- DO NOT tank mix GF-3967 with bentazon products or severe crop injury may occur.
- DO NOT tank mix GF-3967 with foliar-applied organophosphate insecticides including chlorpyrifos, 
malathion, etc., as severe crop injury may occur.
DO NOT tank mix GF-3967 with other products that contain the same active ingredients as GF-3967 
(rimsulfuron, nicosulfuron and dicamba) unless the label of either tank mix partner specifies the maximum 
rate that may be used.

Nicosulfuron + Rimsulfuron + Dicamba / GF-3967 / Prop Sec 3 / Amend / 03-08-21 Page 12
DO NOT apply the organophosphate insecticide terbufos within 45 days of a preplant or preemergence
application of GF-3967 since crop injury may result.
DO NOT apply GF-3967 within 45 days of crop emergence where the organophosphate insecticide 
terbufos was applied since crop injury may occur. Applications made to corn previously treated with 
chlorpyrifos or other similar organophosphate insecticides may result in unacceptable crop injury.
PRECAUTIONS
GF-3967 may cause injury to desirable trees and plants, particularly beans, cotton, flowers, fruit trees, 
grapes, ornamentals, peas, potatoes, soybeans, sunflowers, tobacco, tomatoes, and other broadleaf 
plants when contacting their roots stems or foliage. These plants are most sensitive to GF-3967 during 
their development or growing stage.
Thoroughly clean application equipment immediately after use. (See Sprayer Cleanup section of this label 
for instructions).
Crop injury may occur following an application of GF-3967 if there is a prolonged period of cold weather
and/or in conjunction with wet soils.
GF-3967 may interact with certain insecticides previously applied to the crop. Crop response varies with 
field corn type, insecticide used, insecticide application method, and soil type.
GF-3967 may be applied to corn previously treated with chlorethoxyfos + bifenthrin, tebupirimphos + 
cyfluthrin, or tefluthrin insecticides or nonorganophosphate (OP) soil insecticides regardless of soil type.
GF-3967 may be applied with pyrethroid type insecticides or with diamide type insecticides.
Applications of GF-3967 to corn previously treated with chlorpyrifos or phorate insecticides may cause 
unacceptable crop injury, especially on soils of less than 4% organic matter.
Application(s) of GF-3967 herbicide to corn during periods of rapid growth may result in temporary 
leaning. Corn will usually become erect within 3 – 7 days. Cultivation must be delayed until after corn is 
growing normally to avoid breakage.
A corn plant’s predisposition to develop fused tissue merging from the whorl (rattail) after the V11 stage 
may increase when a product containing dicamba or other growth regulator herbicides [e.g. GF-3967] is 
applied to small corn (less than 4 inches in height) under early stressful conditions. See 
ENVIRONMENTAL CONDITIONS for a description of these stressful conditions.
Avoid disturbing (e.g., cultivating or mowing) for at least 7 days following application.
WEED RESISTANCE MANAGEMENT
GF-3967 contains the active ingredients nicosulfuron and rimsulfuron in Group 2 and dicamba, a Group 4 
herbicide based on the mode of action classification system of the Weed Science Society of America.
Proactively implementing diversified weed control strategies to minimize selection for weed populations 
resistant to one or more herbicides is a best practice. A diversified weed management program may 
include the use of multiple herbicides with different sites of action and overlapping weed spectrum with or 
without tillage operations and/or other cultural practices. Research has demonstrated that using the 
labeled rate and directions for use is important to delay the selection for resistance.
The continued effectiveness of this product depends on the successful implementation of a weed 
resistance management program.

Nicosulfuron + Rimsulfuron + Dicamba / GF-3967 / Prop Sec 3 / Amend / 03-08-21 Page 13
To aid in the prevention of developing weeds resistant to this product, users should:
x Scout fields before application to ensure herbicides and rates will be appropriate for the weed species 
and weed sizes present.
x Start with a clean field, using either a burndown herbicide application or tillage.
x Control weeds early when they are relatively small (less than 4 inches).
x Apply full rates of this product for the most difficult to control weed in the field at the specified time 
(correct weed size) to minimize weed escapes.
x Scout fields after application to detect weed escapes or shifts in control of weed species.
x Control weed escapes before they reproduce by seed or proliferate vegetatively.
x Report any incidence of non-performance of this product against a particular weed to your sales 
representative, local retailer, or county extension agent.
x Contact your sales representative, crop advisor, or extension agent to find out if suspected resistant 
weeds to these MOAs have been found in your region. DO NOT assume that each listed weed is 
being controlled by multiple sites of action. Products with multiple active ingredients 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.
x If resistance is suspected, treat weed escapes with an herbicide having a site of action other than 
Group 2 or 4 and/or use nonchemical methods to remove escapes, as practical, with the goal of 
preventing further seed production.
x Suspected herbicide-resistant weeds may be identified by these indicators:
x Failure to control a weed species normally controlled by the herbicide at the dose applied, especially 
if control is achieved on adjacent weeds;
x A spreading patch of non-controlled plants of a particular weed species; and
x Surviving plants mixed with controlled individuals of the same species.
Additionally, users should follow as many of the following herbicide resistance management practices as 
is practical:
x Use a broad spectrum soil-applied herbicide with other sites of action as a foundation in a weed 
control program.
x Utilize sequential applications of herbicides with alternative sites of action.
x Rotate the use of this product with non-Group 2 and non-Group 4 herbicides.
x Avoid making more than two applications of this product and any other Group 2 or 4 herbicides within 
a single growing season unless mixed with an herbicide with a different site of action with an 
overlapping spectrum for the difficult-to-control weeds.
x Incorporate non-chemical weed control practices, including mechanical cultivation, crop rotation, 
cover crops and weed-free crop seeds, as part of an integrated weed control program.
x Use good agronomic principles that enhance crop development and crop competitiveness.
x Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant 
weeds.
x Manage weeds in and around fields, during and after harvest to reduce weed seed production.
INTEGRATED PEST MANAGEMENT
This product may be used as part of an Integrated Pest Management (IPM) program that can include 
biological, cultural, and genetic practices aimed at preventing economic pest damage. IPM principles and 
practices include field scouting or other detection methods, correct target pest identification, population 
monitoring, and treating when target pest populations reach locally determined action thresholds. Consult 
your state cooperative extension service, professional consultants or other qualified authorities to 
determine appropriate action treatment threshold levels for treating specific pest/crop systems in your 
area.
MANDATORY SPRAY DRIFT MANAGEMENT
Aerial Applications:

Nicosulfuron + Rimsulfuron + Dicamba / GF-3967 / Prop Sec 3 / Amend / 03-08-21 Page 14
x DO NOT release spray at a height greater than 10 feet above the 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 use 
a Coarse or coarser droplet size (ASABE S572.1).
x For all other applications, applicators are required to use a Medium or coarser droplet size (ASABE 
S572.1).
x The boom length must not exceed 65% of the wingspan for airplanes or 75% of the rotor blade 
diameter for helicopters.
x Applicators must use one-half swath displacement upwind at the downwind edge of the field.
x Nozzles must be oriented so the spray is directed toward the back of the aircraft.
x DO NOT apply when wind speeds exceed 10 miles per hour at the application site.
x DO NOT apply during temperature inversions. 
Ground Boom Applications:
x Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet above the 
ground or crop canopy unless making a turf, pasture, or rangeland application, in which case applicat
may apply with a nozzle height no more than 4 feet above the ground.
x For applications prior to the emergence of crops and target weeds, applicators are required to use a 
Coarse or coarser droplet size (ASABE S572.1).
x For all other applications, applicators are required to use a Medium or coarser droplet size (ASABE 
S572.1).
x DO NOT apply when wind speeds exceed 10 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.
Controlling Droplet Size – Aircraft
x Adjust Nozzles - Follow nozzle manufacturers recommendations for setting up nozzles. Generally, to 
reduce fine droplets, nozzles should be oriented parallel with the airflow in flight.
BOOM HEIGHT – Ground Boom
Use the lowest boom height that is compatible with the spray nozzles that will provide uniform coverage. 
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. When applying aerially to crops, DO NOT
release spray at a height greater than 10 feet above the crop canopy, unless a greater application height

Nicosulfuron + Rimsulfuron + Dicamba / GF-3967 / Prop Sec 3 / Amend / 03-08-21 Page 15
is necessary for pilot safety.
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. 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. Avoid applications during temperature inversions.
WIND
Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND 
CONDITIONS. 
x Applicators need to be familiar with local wind patterns and terrain that could affect spray drift.

emerged and are actively growing.
Tank Mixtures in Fallow
GF-3967 may be used as a fallow treatment and may be tank mixed with other herbicides that are 
registered for use in fallow for improved control of emerged weed species. Read and follow all 
instructions on this label and the labels of any tank mix partner before using any other herbicide in 
mixtures with GF-3967. If the specifications on the tank mix partner label conflict with this GF-3967 label, 
DO NOT use in a tank mixture with GF-3967.
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.
FIELD CORN GROWN FOR GRAIN OR SILAGE

Nicosulfuron + Rimsulfuron + Dicamba / GF-3967 / Prop Sec 3 / Amend / 03-08-21 Page 16
GF-3967 can be applied to many field corn hybrids with a relative maturity (RM) of 77 days or more. 
Consult with your seed supplier before applying GF-3967 to any corn types where specific seed company 
publications indicate “Warning”, “Crop Response Warning”, or “Sensitive” notations for the use of some 
ALS herbicides. As noted in the seed company publications, sulfonylurea herbicides, including GF-3967,
must be used with caution on these hybrids. DuPont does not have access to all seed company data. 
Consequently, injury arising from the use of GF-3967 herbicide on the above types of hybrids is the 
responsibility of the user. Consult with your local sales representative or the Label Web Site for any 
additional supplemental labeling information relative to potential corn hybrid sensitivity to GF-3967.
PREPLANT/PREEMERGENCE
Up to 2 applications of GF-3967 herbicide may be made during a growing season. Sequential 
applications must be separated by a minimum of 14 days.
Rate
Apply single application of GF-3967 at 4.0 ounces per acre before corn emergence. See cumulative 
rimsulfuron rate limitation as noted above. Consult technical bulletins, fact sheets or supplemental 
labeling for additional application rate information.
Timing to Crop
Apply GF-3967 herbicide using conventional, conservation tillage, or no-till crop management systems 
and apply using either preplant, preplant incorporated (less than 2” deep), or preemergence for use in 
field corn production.
Applications of GF-3967 made before weed emergence will provide residual control of labeled weeds. 
Control of emerged weeds will require the addition of spray adjuvants, and can be further enhanced with 
additional tank mix partners as noted in this label.
Preplant Surface Applied – Apply GF-3967 up to 30 days prior to planting. GF-3967 is best used in a 
planned sequential application program, followed by GF-3967 or STEADFAST® Q, tank mixed with 
appropriate corn herbicide partners post applied. Refer to the label of the respective sequential partner for 
specific use directions.
Preplant/Preemerge Burndown – Apply GF-3967 when weeds are present at the time of
treatment in a tank mixture with crop oil concentrate or methylated seed oil for burndown of labeled 
weeds 3” or less in height. When weeds are greater than 3” in height or weeds not controlled by GF-3967 
are present, the addition of burndown herbicide (i.e. glyphosate, paraquat, dicamba, and/or 2,4-D) is 
advised. If giant ragweed, common cocklebur, henbit, Pennsylvania smartweed or purple deadnettle are 
present at the time of application, the addition of atrazine will improve control. Observe direction for use 
and precaution and restrictions on the label of the burndown herbicide. When mixing with liquid nitrogen 
fertilizer or glyphosate, substitute a non-ionic surfactant for crop oil.
POSTEMERGENCE
Rate
Apply GF-3967 at 4.0 ounces per acre as a postemergence broadcast application.
Timing to Crop
Apply GF-3967 any time after corn has reached 4 inches in height (V2). DO NOT apply to corn taller than 
20 inches or exhibiting 7 or more leaf collars, whichever is more restrictive. While GF-3967 has a wide 
application window, research has shown best results are obtained when applications are made early 
postemergence when corn and weeds are small. Target applications to corn that is less than 12” tall for 
best overall performance. Applications of GF-3967 made after weed emergence will provide contact 
control of labeled weeds as well as limited residual control of later emerging weeds.

Nicosulfuron + Rimsulfuron + Dicamba / GF-3967 / Prop Sec 3 / Amend / 03-08-21 Page 17
Timing to Emerged Weeds
Apply GF-3967 when weeds are young and actively growing, but before they exceed the sizes listed on 
this label. Applications made to weed sizes greater than those listed on these product labels may result in 
incomplete control. Competition due to incomplete control may reduce yields.
Sequential Application - Postemergence
Apply GF-3967, ACCENT® Q or REVULIN™ Q herbicide 14 or more days after the initial GF-3967
application to control grasses and weeds that may emerge later in the season. Refer to the ACCENT® Q 
or REVULIN™ Q label for weeds controlled, proper size of weeds, rates, corn sizes, and other 
information. 
SPRAY ADJUVANTS
For control of emerged weeds, application of GF-3967 must include a nonionic surfactant and an 
ammonium nitrogen fertilizer. If applied in tank mix combination with a glyphosate or glufosinate herbicide 
that contains a built-in adjuvant system, no additional surfactant needs to be added. Crop oil concentrate 
may be used in place of nonionic surfactant for burndown applications of GF-3967 made before crop 
emergence. Consult local fact sheets, technical bulletins, and service policies prior to using other 
adjuvant systems. Products must contain only EPA-exempt ingredients (40 CFR 1001).
Petroleum Crop Oil Concentrate (COC) or Modified Seed Oil (MSO)
• Apply at 1% v/v (1 gallon per 100 gallons spray solution) or 2% under arid conditions.
• MSO adjuvants may be used at 0.5% v/v (0.5 gallon per 100 gallons spray solution) if specifically noted 
on adjuvant product labeling.
• Oil adjuvants must contain at least 80% high quality, petroleum (mineral) or modified vegetable seed oil 
with at least 15% surfactant emulsifiers.
Nonionic Surfactant (NIS)
• Apply at 0.25% v/v (1 qt per 100 gal spray solution).
• Surfactant products must contain at least 60% nonionic surfactant with a hydrophilic/lipophilic balance
(HLB) greater than 12.
Ammonium Nitrogen Fertilizer
• Use 2 qt/acre of a high-quality urea ammonium nitrate (UAN) including 28%N or 32%N, or 2 lb/acre of a 
spray-grade ammonium sulfate (AMS).
• DO NOT use liquid nitrogen fertilizer as the total carrier solution after crop emergence.
Special Adjuvant Types
Combination adjuvant products may be used at doses that provide the required amount of NIS and 
ammonium nitrogen fertilizer. Consult product literature for use rates and restrictions.

Tank Mixtures with Glufosinate
GF-3967 may be tank mixed with glufosinate herbicides if applications are made to glufosinate-resistant 
corn hybrids.
When used in tank mixtures with glufosinate herbicide, 4.0 ounces/acre GF-3967 will deliver improved 
burndown and/or limited residual activity of several broadleaf and grass weeds including velvetleaf, 
redroot pigweed, common lambsquarters, and certain foxtail spp. as compared to glufosinate alone.
FOR ALL APPLICATION TIMINGS
Other than the exceptions noted, and in addition to the tank mix partners indicated in the fallow and 
postemergence sections above, GF-3967 may be applied in tank mixture with glyphosate plus other 
products registered for use in field corn.
GF-3967 may be applied in tank mix combinations with full or reduced rates of other products provided:
• The tank mix product is labeled for the same timing, method of application, adjuvants, and use 
restrictions as other products used in the tank mixture.
• The tank mixture is not specifically prohibited on the label of the tank mix product.
Tank Mixing 
Weed control and crop response with tank mixtures not specifically specified in this label are the 
responsibility of the user and manufacturer of the tank mix product.
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.
MIXING INSTRUCTIONS
1. Fill the tank 1/4 to 1/3 full of water.
2. While agitating, add the required amount of GF-3967.
3. Continue agitation until the GF-3967 is fully dispersed, at least 5 minutes.
4. Once the GF-3967 is fully dispersed, maintain ag itation and continue filling tank with water. 
Thoroughly mix GF-3967 with water before adding any other material.
5. As the tank is filling, add the required spray adjuv ants (crop oil concentrate, nonionic surfactant, or 
ammonium nitrogen fertilizer).
6. If the mixture is not continuously agitated, settling will occur. If settling occurs, thoroughly re-agitate 
before using.
7. Apply GF-3967 spray mixture within 24 h ours of mixing to avoid product degradation.
8. If GF-3967 and a tank mix partner are to be applied in multiple loads, pre-slurry the GF-3967in clean 
water prior to adding to the tank. This will prevent the tank mix partner from interfering with the 
dissolution of the GF-3967.
TANK MIX COMPATIBILITY TESTING
Perform a jar test prior to tank mixing to ensure compatibility of GF-3967 and other pesticides. Use a clear 
glass quart jar with lid and mix the tank mix ingredients in their relative proportions. Invert the jar

Nicosulfuron + Rimsulfuron + Dicamba / GF-3967 / Prop Sec 3 / Amend / 03-08-21 Page 21
containing the mixture several times and observe the mixture for approximately 1/2 hour. If the mixture 
balls-up, forms flakes, sludges, gels, oily film or layers, or other precipitates, it is not compatible and the 
tank mix combination must not be used.

* On sprinkler irrigated fields in Idaho, Utah, and Northern Nevada it is best to use deep fall tillage including plowing prior to 
planting alfalfa. Product degradation may be less on furrow irrigated soils and may result in some crop injury.
** For soils with pH less than 6.5.
*** At least one inch of rainfall/irrigation must occur between application and planting or crop injury may occur.
† 18 months in the Red River Valley region of ND and MN. In all other areas, the rotation intervals must be extended to 18 
months if drought conditions prevail after application and before the rotational crop is planted, unless sprinkler irrigation has 
been applied and totals greater than 15" during the growing season.
†† Except in Oklahoma and Texas west of Route 183, where the rotational interval is 10 months.

SPRAYER PREPARATION OR CLEANUP
It is important that spray equipment is clean and free of previous pesticide deposits before using GF-3967 
and then properly cleaned out following application. Clean all application equipment before applying GF-
3967. Follow the cleanup procedures specified on the label of the product previously sprayed. If no 
cleanup procedure is provided, use the procedure that follows. Immediately following applications of GF-
3967, thoroughly clean all mixing and spray equipment to avoid subsequent crop injury.
Note:
x When cleaning spray equipment before applying GF-3967, read and follow label directions for proper 
rinsate disposal of the product previously sprayed.
x Steam cleaning of aerial spray tanks will help to dislodge any visible pesticide deposits.
x When spraying or mixing equipment will be used over an extended period to apply multiple loads of 
GF-3967, partially fill the tank with fresh water at the end of each day of spraying, flush the boom and 
hoses, and allow to sit overnight.
Cleanup Procedure
1. Drain the tank and thoroughly hose down the interior surfaces. Flush the tank, hoses, and boom with 
clean water for a minimum of 5 min.
2. Partially fill the tank with clean water and add one gallon of household ammonia* (containing 3% 
active) for every 100 gallons of water. Finish filling the tank with water, then flush the cleaning 
solution through the hoses, boom, and nozzles. Add more water to completely fill the tank and allow 
to agitate/recirculate for at least 15 min. Again, flush the hoses, boom, and nozzles with the cleaning 
solution, then drain the tank.
3. Repeat Step 2.
4. Remove the nozzles, screens and the end caps of sprayer booms and clean separately in a bucket 
containing the cleaning agent and water.
5. Thoroughly rinse the tank with clean water for a minimum of 5 min, flushing the water through the 
hoses and boom.
* Equivalent amounts of an alternate strength ammonia solution or a tank cleaner may be used.
