Image rebuild (skip scrape) / build (push) Failing after 1h37m12s
docker: production image + Gitea Actions for monthly refresh
Dockerfile: self-contained image with corpus + Chroma + BM25 baked
in. Drawbar's compose pulls + runs without volume mounts. Built from
sources.json (labels schema), PRODUCT_NAME=crop_chem by default,
HYBRID_SEARCH=true (always-on for production quality). RERANK_URL +
OLLAMA_URL get set at compose time.

.gitea/workflows/refresh.yml: monthly cron (1st @ 06:00 UTC) does
full scrape → reindex → image push. Scrapes Bayer (~30 min) +
EPA PPLS row-crop filtered (~7h). Skips reindex+push if no corpus
diff. Tags pushed: :latest, :<sha12>, :corpus-<YYYY.MM.DD>.

.gitea/workflows/image-only.yml: on-demand or auto on code-only
pushes to main (paths: docs_mcp/, rag/, scrape/, requirements.txt,
Dockerfile, sources.json). Reindexes from committed corpus, builds
image, pushes. ~10 min vs ~9h full refresh.

.gitignore: corpus/ now COMMITTED (4,159 labels, 265 MB of .md +
sidecars). Lets image-only.yml rebuild indexes without re-scraping.
chroma/ + bm25/ still gitignored (regenerable binary indexes).

.dockerignore: drops venv, eval results, PLAN/README/CLAUDE.md,
deploy/, .git/ — keeps the image lean. corpus + chroma + bm25
explicitly NOT in dockerignore (those go INTO the image).

Dear Wes Marchione:
The amended label referred to above, submitted in connection with registration under the
Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), as amended, is acceptable. This
approval does not affect any conditions that were previously imposed on this registration. You
continue to be subject to existing conditions on your registration and any deadlines connected
with them.
A stamped copy of your labeling is enclosed for your records. This labeling supersedes all
previously accepted labeling. You must submit one copy of the final printed labeling before you
release the product for shipment with the new labeling. In accordance with 40 CFR 152.130(c),
you may distribute or sell this product under the previously approved labeling for 18 months
from the date of this letter. After 18 months, you may only distribute or sell this product if it
bears this new revised labeling or subsequently approved labeling. “To distribute or sell” is
defined under FIFRA section 2(gg) and its implementing regulation at 40 CFR 152.3.
Should you wish to add/retain a reference to the companys website on your label, then please
be aware that the website becomes labeling under FIFRA and is subject to review by the
Agency. If the website is false or misleading, the product would be misbranded and unlawful to
sell or distribute under FIFRA section 12(a)(1)(E). 40 CFR 156.10(a)(5) lists examples of
statements EPA may consider false or misleading. In addition, regardless of whether a website
is referenced on your products label, claims made on the website may not substantially differ
from those claims approved through the registration process. Therefore, should the Agency find

USER SAFETY RECOMMENDATIONS
USERS SHOULD:
x Remove clothing/PPE immediately if pesticide gets inside. Then wash thoroughly and put on
clean clothing.
x Remove PPE immediately after handling this product. Wash the outside of gloves before
removing. As soon as possible, wash thoroughly and change into clean clothing.
ENVIRONMENTAL HAZARDS
DO NOT apply directly to water, or to areas where surface water is present, or to intertidal areas below
the mean high water mark. DO NOT contaminate water when disposing of equipment washwaters or
rinsate.
Groundwater Advisory
This product has properties and characteristics associated with chemicals detected in groundwater. 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 rainwater. 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 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 affect 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.
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 in your State responsible for pesticide regulation.
Resolve
® Q must be used in accordance with the directions for use on this label or as otherwise permitted
by FIFRA. Always read the entire label including the Limitation of Warranty and Liability.

PRODUCT INFORMATION
Resolve Q must be used only in accordance with instructions on this label. To the extent consistent with
applicable law, Corteva Agriscience will not be responsible for losses or damage resulting from use of this
product in any manner not specified by Corteva Agriscience.
Resolve Q herbicide is a water soluble granule which is a selective herbicide for burndown and residual
control of certain annual grass and broadleaf weeds.
Resolve Q can be tank mixed with a variety of herbicides to improve burndown and residual control;
however, the most restrictive label must be followed.
Resolve Q 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 Resolve Q into the soil. Susceptible
weeds will generally 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 Resolve Q may be less effective on weeds stressed from adverse environmental
conditions (including extreme temperatures or moisture), abnormal soil conditions or cultural practices.
Resolve Q 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 Resolve Q
and make certain corn seeds are below the tilled area.
Resolve Q is best used in a planned sequential application herbicide program, following a
preplant/preemergence application of other pre-applied corn herbicides. Refer to the label of the
respective corn herbicide partner for specific use directions.
For postemergence applications of Resolve Q, if activating rainfall or sprinkler irrigation (>0.5 inch) is not
received after application, follow with a cultivation or with a sequential application of another
postemergence corn herbicide as needed.
Resolve Q is rainfast in 4 hours.

R6V / Resolve Q / Amendment / 06-12-2025 Page 13
WEED RESISTANCE MANAGEMENT
Resolve Q, 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:
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 Resolve Q herbicide 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 esc apes 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 company
representative, local retailer, or county extension agent.
x Contact your company 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.
x 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.
x Suspected herbicide-resistant weeds may be identified by these indicators:
o Failure to control a weed species normally controlled by the herbicide at the dose
applied, especially if control is achieved on adjacent weeds;
o A spreading patch of non-controlled plants of a particular weed species; and
o 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 herbicides.
x Avoid making more than two applications of Resolve Q 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.
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.
R6V / Resolve Q / Amendment / 06-12-2025 Page 14
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
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 rangeland application, in which case applicators 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.
Aerial Applications:
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.
Boom-less Ground Applications:
x Applicators are required to use a Medium or coarser droplet size (ASABE S572.1) for all
applications.
x DO NOT apply when wind speeds exceed 10 miles per hour at the application site.
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.
R6V / Resolve Q / Amendment / 06-12-2025 Page 15
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 ft above the crop canopy, unless a greater application height is
necessary for pilot safety.
Boom-less Ground Applications:
x Setting nozzles at the lowest effective height will help to reduce the potential for spray drift.
Handheld Technology Applications:
x Take precautions to minimize spray drift.
SHIELDED SPRAYERS
Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded sprayers. Verify that
the shields are not interfering with the uniform deposition of the spray on the target area.
TEMPERATURE AND HUMIDITY
When making applications in hot and dry conditions, use larger droplets to reduce effects of evaporation.
TEMPERATURE INVERSIONS
Drift potential is high during a temperature inversion. 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.
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 additives 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

Timing to Crop & Weeds
Resolve Q 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
Resolve Q may be used as a fallow treatment and may be tank mixed with other herbicides that are
registered for use in fallow including glyphosate, paraquat, glufosinate, saflufenacil, 2,4-D LVE, and
dicamba herbicides for improved control of emerged weed species.
It is the pesticide users 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 - Preplant/Preemergence
Rate
Apply Resolve Q at 1.25 2.5 ounce per acre before corn emergence. See cumulative rimsulfuron rate
limitation noted in Product Information. Resolve Q at 1.25 1.5 ounce per acre fits most
preemergence/preplant applications.
Timing to Crop
Resolve Q 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 Resolve Q 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 2”
incorporation. DO NOT incorporate Resolve Q deeper than 2” or weed control may be reduced.
Preplant/Preemerge Burndown: Apply Resolve Q when weeds are young and actively growing.
R6V / Resolve Q / Amendment / 06-12-2025 Page 17
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 Resolve Q 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
directions 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 Resolve Q herbicide during planting (behind the planter after furrow closure) or
after planting.
Sequential Application - Preemergence
Resolve Q 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 herbicides. Refer to the preemergence herbicide label
for use restrictions, application information, rotational crop guidelines, and cautionary statements prior to
applying Resolve Q.
DO NOT apply Resolve Q to corn that exhibits herbicide injury from previous applications made to the
current or preceding crop.
Field Corn Grown for Grain or Silage Postemergence
Rate
Apply Resolve Q at 1.25 ounces per acres as a postemergence broadcast application.
Timing to Crop
Apply Resolve Q to corn that is up to 20 inches tall. DO NOT apply to corn taller than 20 inches or
exhibiting 7 or more leaf collars, whichever is more restrictive. While Resolve Q 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 Resolve Q made after weed emergence will provide contact control of labeled weeds as
well as limited residual control of later emerging weeds.
Timing to Emerged Weeds
Apply Resolve Q when grasses are young and actively growing, but before they exceed the sizes listed
on this label.
On glyphosate resistant corn, glyphosate may be applied with Resolve Q 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 Resolve Q after weeds emerge but before
they reach the maximum size listed on the glufosinate herbicide label.
Applications made to weed sizes greater than those listed on these product labels may result in
incomplete control. Grass competition due to incomplete control may reduce yields.
R6V / Resolve Q / Amendment / 06-12-2025 Page 18
Sequential Application - Postemergence
Apply other rimsulfuron containing herbicides 14 or more days after the Resolve Q application to control
grasses that may emerge later in the season. Refer to the label for weeds controlled, proper size of
weeds, rates, corn sizes, and other information. When following a Resolve Q application, DO NOT apply
more than 0.0625 lb active ingredient rimsulfuron and 0.0469 lb active ingredient thifensulfuron-methyl
per acre per year from all sources.
Spray Adjuvants
For control of emerged weeds, application of Resolve Q must include a crop oil concentrate, modified
seed oil or a nonionic surfactant. In addition, an ammonium nitrogen fertilizer must be used unless
specifically prohibited by the tank mix partner labeling. Crop oil concentrate/modified seed oil plus
ammonium nitrogen fertilizer is the preferred adjuvant system for Resolve Q for control of emerged
weeds. When applied in tank mix combination with a glyphosate or glufosinate herbicide that contains a
built-in adjuvant system, ensure the total adjuvant load is equivalent to the directions on this label. Select
adjuvants authorized for use with both products.
Consult local Corteva Agriscience fact sheets, technical bulletins, and service policies prior to using other
adjuvant systems. Products must contain only EPA-exempt ingredients.
DO NOT use 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 Resolve Q.
Petroleum Crop Oil Concentrate (COC) or Modified Seed Oil (MSO)
x Apply at 1% v/v (1 gallon per 100 gallons spray solution) or 2% under arid conditions.
x 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.
x 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)
x Apply at 0.25% v/v (1 qt per 100 gal spray solution).
x Surfactant products must contain at least 60% nonionic surfactant with a hydrophilic/lipophilic balance
(HLB) greater than 12.
Ammonium Nitrogen Fertilizer
x 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).
x DO NOT use liquid nitrogen fertilizer as the total carrier solution after crop emergence.
Special Adjuvant Types
x 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.
Weeds Controlled/Suppressed
For best control of emerged weeds, apply Resolve Q to grasses 3” or less, broadleaf weeds 4” or less
and winter annuals/biennials 6” or less. Make application prior to flowering.
Refer to the Spray Adjuvants section for additional information on proper adjuvant selection.

Tank Mixtures - Additional Control of Broadleaf and Grass Weeds
Resolve Q may be tank mixed with other products registered for use in corn. Consult tank mix partner
labeling for rate and soil-type restrictions.
Ensure the tank mix product is labeled for the same timing, method of application, adjuvants, and use
restrictions as Resolve Q, as well as other products used in the tank mixture.
It is the pesticide users 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.
Resolve Q may be tank mixed with topramezone plus atrazine for improved burndown or residual control
of several broadleaf weeds including common waterhemp, common ragweed, common lambsquarters,
and velvetleaf. When applying mixtures of Resolve Q plus topramezone, the use of methylated seed oil is
advised. Refer to Impact label for additional information regarding application timing, tank mixtures,
adjuvants, and rotational crops.
Resolve Q may be tank mixed with fluroxypyr herbicides, for improved control of kochia. Use higher
labeled rates when weed infestation is heavy. Refer to the specific fluroxypyr product labels for
application rates, timing and restrictions. Resolve Q may be tank mixed with fluroxypyr and dicamba for
broader spectrum weed control.
Tank Mix Compatibility Testing
Perform a jar test prior to tank mixing to ensure compatibility of Resolve Q 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-up, forms flakes, sludge, gel, oily film or layers, or other precipitates, it is not compatible and the
tank mix combination must not be used.
Mixing Instructions
Fertilizer Carrier Instructions
Resolve Q may be mixed with water or pre-dissolved in water and added to liquid fertilizer for
preemergence application. When using liquid fertilizer as the carrier, always pre-slurry Resolve Q in water
before adding fertilizer solutions. Add the Resolve Q slurry to the final complete liquid fertilizer mixture
DO NOT add Resolve Q during the fertilizer mixing process. Always use good agitation while adding the
Resolve Q slurry to liquid fertilizers and maintain good agitation until sprayed. When using liquid fertilizer
as the carrier, conduct a compatibility test with all components prior to mixing.
DO NOT use with spray additives or liquid fertilizer carriers that alter the pH of the spray solution below
pH 5.0 or above pH 9.0 as rapid product degradation can occur. Spray solutions of pH 6.0 -8.0 allow for
optimum stability of Resolve Q.

Water Carrier Instructions
1. Fill the tank 1/3 to 1/2 full of water.
2. While agitating, add the required amount of Resolve Q.
3. Continue agitation until the Resolve Q is fully dispersed, at least 5 minutes. When the water
temperature is 40°F or less, it is important to allow agitation and mixing to occur for the full 5 minutes
to ensure the product is completely dissolved.
4. Once the Resolve Q is fully dispersed, maintain agitation and continue filling tank with water.
Thoroughly mix Resolve Q with water before adding any other material including water conditioners
or other additives.
5. As the tank is filling, add tank mix partners in the proper mixing order.
6. If the mixture is not continuously agitated, settling will occur. If settling occurs, thoroughly re-agitate
before using.
7. At the end of the day, or for extended periods of time between Resolve Q applications, it is advised to
flush boom hoses and lines of spray solution and recharge with clean water. This will aid in proper
sprayer cleanout when concluding Resolve Q applications before moving on to spray other
products/crops.
8. Apply Resolve Q spray mixture within 48 hours of mixing to avoid product degradation.
If the selected companion herbicide has a ground or surface water advisory, consider this advisory when
using the companion herbicide.
Application and Spray Volumes
Ground Applications (also refer to SPRAY 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.
Heavy crop residues may reduce burndown control of emerged weeds if residues impede spray
coverage. Higher spray volumes and pressures can improve burndown control in heavy crop residue
situations.
Ensure that equipment is set up to avoid applying an excessive rate directly over the rows and into the
corn plant whorl. Overlaps or starting, stopping, slowing, and turning while spraying may result in crop
injury.
Aerial Applications (also refer to SPRAY DRIFT MANAGEMENT section)
Use nozzle types and arrangements that will provide optimum spray distribution and maximum coverage
at a minimum of 2 GPA.
Aerial application is not permitted in the State of New York.

***On soils with pH 6.5 or less
****Winter canola, winter carinata, winter camelina, and winter cress can be planted in AL, AR, IL, IN, KY, MO, MS, and TN as a
second crop (double crop) a minimum of 4 months after application. If drought conditions are present after application, some st and
loss 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 ap plied 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

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 Resolve Q on field corn:
Rotation Crop Interval
(months)
Alfalfa 4
Carrots 10
Cucumber 10
Grass, pasture, hay, seed 4
Mint 4
Onions 10
Peas 8
For Rotation to Alfalfa: Resolve Q in field corn not to exceed 1.25 ounces per year in Adams, Grant,
Douglas and Lincoln counties of Washington, and Resolve Q 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: Resolve Q in field corn not to exceed 1.88 ounces per acre per
year in Adams, Grant, Douglas and Lincoln counties of Washington, and Resolve Q in field corn not to
exceed 2.5 ounces per acre per year in Benton, Franklin, Klickitat, Walla Walla and Yakima counties in

all areas.
Precaution
Resolve Q must not be used in a tank mix 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 Resolve
Q and then properly cleaned out following application. Clean all application equipment before applying
Resolve Q. 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
Resolve Q, thoroughly clean all mixing and spray equipment to avoid subsequent crop injury.
R6V / Resolve Q / Amendment / 06-12-2025 Page 25
x When cleaning spray equipment before applying Resolve Q, read and follow label directions for
proper rinsate disposal of the product previously sprayed.
x When spraying or mixing equipment will be used over an extended period to apply multiple loads of
Resolve Q, 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. This will prevent the buildup of dried pesticide deposits, which
can accumulate in the application equipment.
After Spraying Resolve Q and Before Spraying Crops Other than Fallow or Field Corn
To avoid subsequent injury to desirable crops, thoroughly clean all mixing and spray equipment
immediately following applications of Resolve Q as follows:
1. Empty the tank and drain the sump completely.
2. Spray the tank walls with clean water using a minimum volume of 10% of the tank volume. Circulate
the water through the lines, including all bypass lines, for at least two minutes. Flush the boom well
and empty the sprayer. Completely drain the sump.
3. Repeat step 2.
4. Remove the nozzles, screens and the end caps of sprayer booms and clean separately in a bucket
containing water.
The rinsate solution may be applied back to the crop(s) specified on this label. DO NOT exceed the
maximum labeled use rate. If cleaners are used, consult the cleaner label for rinsate disposal instructions.
If no instructions are given, dispose of the rinsate on site or at an approved waste disposal facility.
Notes:
1. Always start with a clean spray tank. Ensure boom sections between end nozzles and the end of the
boom are clean of deposits (It is advised to remove end caps and visually inspect). If needed,
thoroughly flush rinse water through the boom sections with the end caps removed to ensure booms
are clean and free of any residue or deposits.
2. Steam-cleaning aerial spray tanks is advised to facilitate the removal of any caked deposits.
3. When Resolve Q is tank mixed with other pesticides, all cleanout procedures for each product must
be examined and the most rigorous procedure must be followed.
4. Follow any pre-cleanout guidelines advised on other product labels.
