the mean high water mark. DO NOTcontaminate water when disposing of equipment wash water or 
rinsate. DO NOTapply where/when conditions could favor runoff.
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.
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.

PRODUCT INFORMATION
GF-3969 herbicide is a water soluble granule which is a selective herbicide for burndown and residual 
control of certain annual grass and broadleaf weeds. 
GF-3969 can be tank mixed with a variety of herbicides to improve burndown and residual control; 
however, the most restrictive label must be followed.
GF-3969 is absorbed through the roots and leaf tissue of plants, rapidly inhibiting the growth of 
susceptible weeds. Rainfall or sprinkler irrigation is needed to move GF-3969 into the soil. Susceptible 
weeds will not emerge from a 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, stunted and noncompetitive.
The herbicidal action of GF-3969 may be less effective on weeds stressed from adverse environmental 
conditions (including extreme temperatures or moisture), abnormal soil conditions or cultural practices.
GF-3969 residual is most effective in controlling weeds when adequate rainfall is received within 5-7 days 
after application. If cultivation is necessary because of soil crusting, soil compaction or weed germination 
before rain occurs, use shallow tillage including rotary hoe to lightly incorporate GF-3969 and make 
certain corn seeds are below the tilled area.
GF-3969 is best used as part of a sequential application herbicide program, following a before-planting 
application of BASIS® Blend, CINCH®, INSTIGATE™, LEADOFF®, PREQUEL®, or RESOLVE® Q 
herbicides and/or other pre-applied corn herbicides. Refer to the label of the respective corn herbicide 
partner for specific use directions.
For post emergence applications of GF-3969, if activating rainfall or sprinkler irrigation (>0.5 inch) is not 
received within 5 to 7 days after application, follow with a cultivation or with a sequential application of 
ACCENT® Q herbicide, REVULIN™ Q herbicide, STEADFAST® Q, or glyphosate (including ABUNDIT® 
Edge) as needed.

DO NOTtank mix GF-3969 with foliar-applied organophosphate or carbamate insecticides, including
chlorpyrifos, malathion, parathion, etc., as severe crop injury may occur. To avoid crop injury or 
antagonism, apply these products at least 7 days before or 7 days after the application of GF-3969.
DO NOTapply GF-3969 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. Any 
crop injury or yield loss resulting from these applications are the responsibility of the grower.
DO NOTapply GF-3969 to corn that exhibits herbicide injury from previous applications made to the 
current or preceding crop.
DO NOTuse liquid nitrogen fertilizer as the total carrier solution for postemergence applications. 
Injury or loss of desirable trees or vegetation may result from failure to observe the following:
- DO NOTapply GF-3969 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.
- DO NOTuse on lawns, walks, driveways, tennis courts. Prevent drift or spray onto desirable plants. 
- DO NOTcontaminate any body of water.
DO NOTgraze, feed forage, grain or fodder (stover) from treated areas to livestock within 30 days of
GF-3969 application. 
DO NOTharvest grain within 70 days of GF-3969 application.
DO NOTharvest forage or stover within 30 days of GF-3969 application.
DO NOTuse aerial application to apply GF-3969 unless specified otherwise under the specific crop 
section on the label.
DO NOTapply this product by air in New York. 
DO NOTapply this product through any type of irrigation system.
DO NOTuse flood or furrow irrigation to apply GF-3969.
DO NOTirrigate GF-3969 into coarse soils at planting time when soils are saturated.
This product contains 0.11 pound of the safener isoxadifen-ethyl per pound of product. Applying the
maximum application rate of GF-3969 at 1.5 ounces per acre will deliver 0.01 pound of isoxadifen-ethyl

Rimsulfuron + Thifensulfuron / GF-3969 / Prop Sec 3 / 03-25-2021 Page 11
per acre. When tank mixing herbicides or using sequential herbicide for applications to field corn, DO 
NOTapply more than a total of 0.17 pound of isoxadifen-ethyl per acre per year.
PRECAUTIONS
GF-3969 may interact with certain insecticides previously applied to the crop. Crop response varies with 
field corn type, insecticide used, insecticide application methods, and soil type.
GF-3969 may be applied to corn previously treated with chlorethoxyfos + bifenthrin, tebupirimphos + 
cyfluthrin, or tefluthrin insecticides, or other non-organophosphate soil insecticides regardless of soil type.
GF-3969 may be applied with pyrethroid type insecticides, including esfenvalerate and lambda-
cyhalothrin, or with diamide type insecticides.
Preplant/Preemergence applications of GF-3969 to field crops where an application of chlorpyrifos or 
phorate is planned may cause unacceptable crop injury, especially on soils of less than 4% organic 
matter.
Crop injury may occur following an application of GF-3969 if there is a prolonged period of cold weather 
and/or in conjunction with wet soils.
Prevent drift or spray onto desirable plants.
Thoroughly clean application equipment immediately after use (See Sprayer Cleanup section of this 
label).
WEED RESISTANCE MANAGEMENT
GF-3969, which contains the active ingredients rimsulfuron and thifensulfuron methyl, is a Group 2 
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.
To aid in the prevention of developing weeds resistant to this product, users should:
Scout fields before application to ensure herbicides and rates will be appropriate for the weed species 
and weed sizes present.
Start with a clean field, using either a burndown herbicide application or tillage.
Control weeds early when they are relatively small (less than 4 inches).
Apply full rates of GF-3969 herbicide for the most difficult to control weed in the field at the specified 
time (correct weed size) to minimize weed escapes.
Scout fields after application to detect weed escapes or shifts in control of weed species.
Control weed escapes before they reproduce by seed or proliferate vegetatively.
Report any incidence of non-performance of this product against a particular weed to your sales 
representative, local retailer, or county extension agent.
Contact your sales representative, crop advisor, or extension agent to find out if suspected resistant 
weeds to this MOA have been found in your region. If resistant biotypes of target weeds have been 
reported, use the application rates of this product specified for your local conditions. Tank mix 
products so that there are multiple effective sites of actions for each target weed.

Rimsulfuron + Thifensulfuron / GF-3969 / Prop Sec 3 / 03-25-2021 Page 12
If resistance is suspected, treat weed escapes with an herbicide having a site of action other than 
Group 2 and/or use nonchemical methods to remove escapes, as practical, with the goal of 
preventing further seed production.
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.
Additionally, users should follow as many of the following herbicide resistance management practices as 
is practical:
Use a broad spectrum soil-applied herbicide with other sites of action as a foundation in a weed 
control program.
Utilize sequential applications of herbicides with alternative sites of action.
Rotate the use of this product with non-Group 2 herbicides.
Avoid making more than two applications of GF-3969 and any other Group 2 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.
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.
Use good agronomic principles that enhance crop development and crop competitiveness.
Thoroughly clean plant residues from equipment before leaving fields suspected to contain resistant 
weeds.
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 consultant or other qualified authorities to 
determine appropriate action treatment threshold levels for treating specific pest / crop systems in your 
area.
MANDATORY SPRAY DRIFT MANAGEMENT
Ground Boom Applications:
Apply with the nozzle height recommended by the manufacturer, but no more than 3 feet above the 
ground or crop canopy unless making a rangeland application, in which case applicators may apply 
with a nozzle height no more than 4 feet above the ground.
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).
For all other applications, applicators are required to use a Medium or coarser droplet size (ASABE 
S572.1).
DO NOTapply when wind speeds exceed 10 miles per hour at the application site.
DO NOTapply during temperature inversions.
Aerial Applications:
DO NOTrelease spray at a height greater than 10 feet above the vegetative canopy, unless a 
greater application height is necessary for pilot safety.
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).
For all other applications, applicators are required to use a Medium or coarser droplet size (ASABE 
S572.1).

Rimsulfuron + Thifensulfuron / GF-3969 / Prop Sec 3 / 03-25-2021 Page 13
The boom length must not exceed 65% of the wingspan for airplanes or 75% of the rotor blade 
diameter for helicopters.
Applicators must use one-half swath displacement upwind at the downwind edge of the field.
Nozzles must be oriented so the spray is directed toward the back of the aircraft.
DO NOTapply when wind speeds exceed 10 miles per hour at the application site.
DO NOTapply during temperature inversions.
Boom-less Ground Applications:
Applicators are required to use a Medium or coarser droplet size (ASABE S572.1) for all 
applications.
DO NOTapply when wind speeds exceed 10 miles per hour at the application site.
DO NOTapply during temperature inversions.
SPRAY DRIFT MANAGEMENT ADVISORIES
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT.
BE AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS. 
IMPORTANCE OF DROPLET SIZE
An effective way to reduce spray drift is to apply large droplets. Use the largest droplets that provide 
target pest control. While applying larger droplets will reduce spray drift, the potential for drift will be 
greater if applications are made improperly or under unfavorable environmental conditions.
Controlling Droplet Size – Ground Boom
Volume -Increasing the spray volume so that larger droplets are produced will reduce spray drift. 
Use the highest practical spray volume for the application. If a greater spray volume is needed, 
consider using a nozzle with a higher flow rate.
Pressure -Use the lowest spray pressure recommended for the nozzle to produce the target spray 
volume and droplet size.
Spray Nozzle -Use a spray nozzle that is designed for the intended application. Consider using 
nozzles designed to reduce drift.
Controlling Droplet Size – Aircraft
Adjust Nozzles -Follow nozzle 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 ft above the crop canopy, unless a greater application height is 
necessary for pilot safety.
Boom-less 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.

Rimsulfuron + Thifensulfuron / GF-3969 / Prop Sec 3 / 03-25-2021 Page 14
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. 
Applicators need to be familiar with local wind patterns and terrain that could affect spray drift.
DRIFT CONTROL ADDITIVES
Using product compatible drift control additives can reduce drift potential. When a drift control additive is 
used, read and carefully observe cautionary statements and all other information on the additive’s label. If 
using an additive that increases viscosity, ensure that the nozzles and other application equipment will 
function properly with a viscous spray solution. Preferred drift control additives have been certified by the 
Chemical Producers and Distributors Association (CPDA).

Timing to Crop & Weeds
GF-3969 may be used as a fallow treatment, in the fall or spring when the majority of weeds have 
emerged and are actively growing.
Tank Mixtures
GF-3969 may be used as a fallow treatment and may be tank mixed with other herbicides that are 
registered for usein fallow including, glyphosate, paraquat, glufosinate, saflufenacil, 2,4-D LVE, and 
dicamba herbicides for improved control of emerged weed species. 
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

Rimsulfuron + Thifensulfuron / GF-3969 / Prop Sec 3 / 03-25-2021 Page 15
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 - Preplant/Preemergence
Application Rate
Apply GF-3969 at 1.25 – 2.5 ounce per acre before corn emergence. See cumulative rimsulfuron rate 
limitation noted in Product Information. GF-3969 at 1.25 – 1.5 ounce per acre fits most 
preemergence/preplant applications.
Timing to Crop
GF-3969 herbicide may be used in conventional, conservation tillage, or no-till crop management systems 
and may be applied either preplant, preplant incorporated (less than 2” deep), or preemergence for use in 
field corn production. Applications of GF-3969 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 Incorporated: Apply to the soil and uniformly incorporate in the top two inches of soil before 
planting using a finishing disc harrow, field cultivator or similar implement capable of providing uniform 
two-inch incorporation. DO NOTincorporate GF-3969 deeper than 2” or weed control may be reduced.
Preplant/Preemerge Burndown: Apply GF-3969 when weeds are young and actively growing.
The addition of crop oil concentrate or methylated seed oil is advised for burndown of labeled weeds. 
When weeds are greater than the maximum height listed or weeds not controlled by GF-3969 are 
present, the addition of a burndown herbicide including glyphosate, glufosinate, 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.
Preemergence: Apply GF-3969 herbicide during planting (behind the planter after furrow closure) or after 
planting.
Sequential Application - Preemergence
GF-3969 may be used as a sequential application in a planned postemergence weed control program in 
corn following a preemergence herbicide. Apply preemergence products including atrazine, BASIS® 
Blend, RESOLVE® Q, CINCH®, INSTIGATE®, LEADOFF® or PREQUEL® herbicides. Refer to the 
preemergence herbicide label for use restrictions, application information, rotational crop guidelines, and 
cautionary statements prior to applying GF-3969.
DO NOTapply GF-3969 to corn that exhibits herbicide injury from previous applications made to the
current or preceding crop.
Field Corn Grown for Grain or Silage - Postemergence
Application Rate
Apply GF-3969 at 1.25 ounces per acre as a postemergence broadcast application. Consult technical 
bulletins, fact sheets or supplemental labeling for additional application rate information.
Timing to Crop
Apply GF-3969 to corn that is up to 20 inches tall. DO NOTapply to corn taller than 20 inches or 
exhibiting 7 or more leaf collars, whichever is more restrictive. While GF-3969 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 post applications to corn less than 12 inches tall for best overall 
performance.

Rimsulfuron + Thifensulfuron / GF-3969 / Prop Sec 3 / 03-25-2021 Page 16
Applications of GF-3969 made after weed emergence will provide contact control of labeled weeds as 
well as residual control of later emerging weeds.
Timing to Emerged Weeds
Apply GF-3969 when grasses and broadleaf weeds are young and actively growing, but before they 
exceed sizes listed on this label. Applications made to weed sizes greater than those listed on this 
product label may result in incomplete control. Grass and broadleaf weed competition due to incomplete 
control may reduce corn yields.
On glyphosate-resistant corn, glyphosate products, including ABUNDIT® Edge, may be applied with GF-
3969 after weeds emerge but before they reach the maximum size listed on the glyphosate herbicide 
label.
On glufosinate-resistant corn, glufosinate may be applied with GF-3969 after weeds emerge but before 
they reach the maximum size listed on the glufosinate herbicide label.
GF-3969 is rainfast in 4 hours.
Sequential Application - Postemergence
GF-3969 may be used as a sequential application in a planned postemergence weed control program in 
corn following a preemergence herbicide.
Apply ACCENT® Q or REVULIN™ Q herbicide 14 or more days after the GF-3969 application to control 
grasses 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. When following a GF-3969 
application, DO NOTuse more than 0.9 ounce per acre of ACCENT® Q (0.031 lb ai nicosulfuron) or 3.4 
ounces per acre of REVULIN™ Q (0.031 lb ai nicosulfuron + 0.078 lb ai mesotrione).
DO NOTapply GF-3969 to corn that exhibits herbicide injury from previous applications made to the 
current or preceding crop.
SPRAY ADJUVANTS
For control of emerged weeds, applications of GF-3969 must include a crop oil concentrate (COC )or a 
high surfactant oil concentrate (HSOC).
The use of a nonionic surfactant (NIS) instead of a COC or HSOC is allowed, but the weed control 
achieved with COC or HSOC is consistently better than NIS. 
The use of methylated seed oil (MSO) adjuvants or MSO blend adjuvants may cause severe crop 
injury to occur. MSO adjuvants are not advised. 
In addition to COC or HSOC, always add spray grade UAN (e.g., 28-0-0) to the spray solution or AMS, 
except if precluded elsewhere on this label.
When applied in tank mix combination with a glyphosate that contains a built-in adjuvant, including
ABUNDIT® Edge, ensure the total adjuvant load is equivalent to the directions on this label. Select 
adjuvants authorized for use with both products.
Consult local fact sheets, technical bulletins or supplemental labels prior to using other adjuvant systems. 
Products must contain only EPA-exempt ingredients.
DO NOTuse with spray additives that alter the pH of the spray solution below 5.0 or above 9.0 as rapid 
product degradation can occur. Spray solutions of pH 6.0 – 8.0 allow for optimum stability of REALM® Q.

Rimsulfuron + Thifensulfuron / GF-3969 / Prop Sec 3 / 03-25-2021 Page 17
Petroleum Crop Oil Concentrate (COC)
Apply at 1% (1 gallon per 100 gallon spray solution), or 2% under arid conditions.
Oil adjuvants must contain at least 80% high quality, petroleum (mineral) oil with at least 15% 
surfactant emulsifiers.
High Surfactant Oil Concentrate (HSOC)
Apply at 0.5% (2 quarts per 100 gallons spray solution). 
Nonionic Surfactant (NIS)
Apply at 0.25% v/v (1 quart per 100 gallon spray solution).
Surfactant products must contain at least 60% nonionic surfactant with a hydrophilic/lipophilic balance 
(HLB) greater than 12.
DO NOTuse liquid nitrogen fertilizer as the total carrier solution for postemergence applications.
Ammonium Nitrogen Fertilizer
Use 2 quarts per acre of a high quality urea ammonium nitrate (UAN) including 28%N or 32%N, or 2 
pounds per acre of a spray-grade ammonium sulfate (AMS).
Special Adjuvant Types
Combination adjuvant products may be used at doses that provide the required amounts of NIS, 
COC, and/or ammonium nitrogen fertilizer. Consult product literature for use rates and restrictions.
WEEDS CONTROLLED/SUPPRESSED
For best control of emerged weeds, apply GF-3969 to grasses 3 inches or less, broadleaf weeds 4 inches 
or less and winter annuals/biennials 6 inches or less. Make application prior to flowering.
Refer to the Spray Adjuvants section for additional information on proper adjuvant selection.

For full season control utilizing a two-pass application program (pre followed by post to corn), follow the 
preemergence application of GF-3969 with a sequential, in-crop application of GF-3969, REVULIN™ Q or 
STEADFAST® Q with appropriate tank mix partners.
For full season control utilizing a one pass preemergence application, mix GF-3969 with atrazine-
containing grass and broadleaf corn herbicides. Depending on the growing season, in-crop post 
applications may be needed to control late grass and weed escapes.
TANK MIXTURES
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.
Postemergence: GF-3969 APPLIED 1.25 oz/acre with Glyphosate

corn hybrids. Consult with your seed supplier to confirm the corn hybrid is glufosinate-resistant” before 
applying any herbicide containing glufosinate. When used in a tank mixture with glufosinate herbicide, 
GF-3969 will deliver improved burndown and/or limited residual activity on the following weeds:
Velvetleaf
Pigweed, redroot
Lambsquarters, common
Foxtail (giant, yellow)
Tank Mixtures - Additional Control of Broadleaf and Grass Weeds
GF-3969 may be tank mixed with other post-emerge labeled grass and broadleaf herbicides including
atrazine, dicamba, Cinch® ATZ, Cinch® ATZ Lite, ACCENT® Q and REVULIN™ Q to provide added 
residual or burndown activity on emerged weeds. Consult tank mix partner labeling for rate and soil-type 
restrictions. Read and follow all manufacturers' label instructions for the companion herbicide(s). DO NOT

Rimsulfuron + Thifensulfuron / GF-3969 / Prop Sec 3 / 03-25-2021 Page 20
use a tank mix partner product if its label conflicts with this GF-3969 label.
Ensure the tank mix product is labeled for the same timing, method of application, adjuvants, and use 
restrictions as GF-3969, as well as other products used in the tank mixture.
As EC formulations, acetochlor or metolachlor herbicides, including CINCH®, can act like an adjuvant in 
certain combinations and thus increase the risk of crop injury. If these tank mixtures are used, the user 
must leave the crop oil concentrate (COC) out of the adjuvant mix.
GF-3969 may be tank mixed with atrazine formulations including CINCH® ATZ, CINCH® ATZ Lite, or 
products that contain the same active ingredients, but special attention must be paid to adjuvant selection 
and/or application method. If any of these tank mixtures are used the user must leave the urea 
ammonium nitrate (UAN) out of the mix. There is still a risk of temporary crop injury in the form of leaf 
burn with these mixtures. To further reduce the risk of crop injury also leave out the crop oil concentrate 
(COC) and replace it with a nonionic surfactant (NIS).
The control of emerged weeds may be reduced due to less than optimum adjuvant effect or weed 
coverage and there is still a risk of temporary crop injury in the form of leaf burn with these mixtures.
The crop safety of all possible tank mixture combinations with REALM® Q which may include physically 
compatible pesticides, fertilizers, adjuvants and/or additives has not been tested.
To the extent consistent with applicable law, DuPont will not be responsible for any crop injury arising 
from the use of a tank mixture that is not specifically described on the GF-3969 product labeling or in 
other DuPont product use instructions.
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 Mix Compatibility Testing
Perform a jar test prior to tank mixing to ensure compatibility of GF-3969 and other pesticides. Use a clear 
quart jar with lid and mix the tank mix ingredients in their relative proportions. Invert the jar containing the 
mixture several times and observe the mixture for approximately 1/2 hour. If the mixture balls-ups, forms 
flakes, sludge, gel, oily film or layers, or other precipitates, it is not compatible, and the tank mix 
combination must not be used.

APPLICATION AND SPRAY VOLUMES
Ground Application (Also refer to theSPRAY DRIFT MANAGEMENT section)
Use a minimum of 15 gallons of water per acre (GPA) to ensure thorough coverage of the weeds and the 
best performance. Use a minimum of 10 GPA for light, scattered stands of weeds.
Avoid spray overlaps as excessive rates may result in adverse crop response.
Ensure that all in-line strainer and nozzle screens in the sprayer are 50-mesh or coarser. 
Maintain adequate agitation at all times, including momentary stops.
Aerial Application (Also refer to theSPRAY DRIFT MANAGEMENT section)
Aerial application is not permitted in the state of New York with this product.
For aerial application only use nozzles producing coarse-ultra coarse droplets. DO NOTuse nozzles 
producing fine-medium size droplets.
Applications must be made in a minimum of 2 gallons of water per acre.
ROTATIONAL CROP GUIDELINES
Rotational crops vary in their crop response to low concentrations of GF-3969 remaining in the soil. The 
amount of GF-3969 that may be present in the soil depends on soil moisture, soil temperature, application 
rate, elapsed time since application and other environmental factors. When GF-3969 is used in 
combination with other products, always follow the most restrictive rotational crop requirements.
Planting unspecified rotational crops, or those rotational crops that are specified at shorter than listed
intervals may result in injury to the rotational crop.
The following rotational intervals must be observed when using GF-3969:
1.25 OZ (0.012 lb ai rimsulfuron and 0.007 lb au thifensulfuron-methyl) MAXIMUM USE RATE

*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.
**Rotational interval to seed corn is 60 days if applying no more than 1.0 ounce per acre in the fall by December 15.
***On soils with pH 6.5 or less
† 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.
†††In the states of AL, AR, GA, KY, LA, MO (bootheel), MS, NC, SC, and TN the recrop interval is 30 days. In the states of KS
and OK the counties containing HWY 81 and east and in MO (excluding the bootheel), IL, IN, OH, and WV the counties that 
contain I-70 and south and the states of DE, MD and VA, the recrop is 60 days.

Application Guidelines for Certain Areas of Oregon and Washington
Field corn grown under sprinkler irrigation with a minimum of 18 inches of water per season. This rotation 
interval is for sand, loamy sand and sandy loam soils having not more than 1.5% organic matter here a 
minimum of 18 inches of sprinkler irrigation is used on the previous corn crop. Injury to the rotated crop 
may occur if less than 18 inches of irrigation is used on the previous field corn crop. For tank mixtures, 
follow the most restrictive rotational crop guideline.
The following revised rotational intervals must be observed when using GF-3969 on field corn:
Rotational Crop Interval (months)
Alfalfa 4
Carrots 10
Cucumber 10
Grass, pasture, hay, seed 4
Mint 4
Onions 10
Peas 8

Rimsulfuron + Thifensulfuron / GF-3969 / Prop Sec 3 / 03-25-2021 Page 23
For Rotation to Alfalfa: GF-3969 in field corn not to exceed 1.25 ounces per year in Adams, Grant, 
Douglas and Lincoln counties of Washington, and GF-3969 in field corn not to exceed 1.88 ounces per 
acre per year in Benton, Franklin, Klickitat, Walla Walla and Yakima counties in Washington and Morrow 
and Umatilla counties in Oregon.
For Rotation to Onions and Carrots: GF-3969 in field corn not to exceed 1.88 ounces per acre per year 
in Adams, Grant, Douglas and Lincoln counties of Washington, and GF-3969 in field corn not to exceed 
2.5 ounces per acre per year in Benton, Franklin, Klickitat, Walla Walla and Yakima counties in 
Washington and Morrow and Umatilla counties in Oregon.
For Rotation to Grass Crops Grown for Seed, Hay or Pasture: GF-3969 in field corn not to exceed 
1.88 ounces per acre per year in Adams, Grant, Douglas and Lincoln counties of Washington, and GF-
3969 Q in field corn not to exceed 2.5 ounces per acre per year in Benton, Franklin, Klickitat, Walla Walla 
and Yakima counties in Washington and Morrow and Umatilla counties in Oregon.
For Rotation to Peas and Mints: GF-3969 in field corn not to exceed 1.88 ounces per acre per year in 
all areas.
DO NOTuse GF-3969 in a tankmix or sequential application program with other soil residual ALS 
inhibiting herbicides in field corn as the combined effects of these herbicides on the planting of 
subsequent crops have not been thoroughly investigated and injury to the following rotation crop may 
occur.
SPRAYER PREPARATION / CLEANUP
It is important that spray equipment is clean and free of previous pesticide deposits before using GF-
3969, and then properly cleaned out following application. Clean all application equipment before 
applying GF-3969. 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-3969, thoroughly clean all mix and spray equipment to avoid subsequent crop injury.
When cleaning spray equipment before applying GF-3969, read and follow label directions for proper 
rinsate disposal of the product previously sprayed.
When spraying or mixing equipment will be used over an extended period to apply multiple loads of 
GF-3969, 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 hose down the interior surfaces with clean water
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 tank with water, then flush the cleaning solution 
through the hoses, boom, and nozzles. Add more water to completely fill the tank and allow agitating / 
re-circulating for at least 15 minutes. 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 minutes, flushing the water through the 
hoses and boom.
*Equivalent amount of an alternate strength ammonia solution or a tank cleaner advised in the bulletin “Sulfonylurea Herbicides, A 
Guide to Equipment Cleanout” may be used.
