Image rebuild (skip scrape) / build (push) Failing after 1h37m12s
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 Agency is in receipt of your Application for Pesticide Notification under Pesticide
|
||
Registration Notice (PRN) 98-10 for the above referenced product. The Registration Division
|
||
(RD) has conducted a review of this request for its applicability under PRN 98-10 and finds that
|
||
the action requested falls within the scope of PRN 98-10.
|
||
|
||
The label submitted with the application has been stamped “NOTIFICATION” and placed in our
|
||
records.
|
||
|
||
The alternate brand name, “DuPont Steadfast Q” has been added to the product record.
|
||
|
||
Should you wish to add/retain a reference to the company’s website on your label, then please be
|
||
aware that the website becomes labeling under the Federal Insecticide, Fungicide, and
|
||
Rodenticide Act (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 product’s label,
|
||
claims made on the website may not substantially differ from those claims approved through the
|
||
registration process. Therefore, should the Agency find or if it is brought to our attention that a
|
||
website contains false or misleading statements or claims substantially differing from the EPA
|
||
approved registration, the website will be referred to the EPA’s Office of Enforcement and
|
||
Compliance.

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 such as
|
||
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,

|
||
|
||
WEED RESISTANCE MANAGEMENT
|
||
|
||
SteadfastSTEADFAST® Q which contains the active ingredients nicosulfuron and rimsulfuron 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 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 DuPont
|
||
company representative, local retailer, or county extension agent.
|
||
x Contact your DuPont company 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 ingredient in this product.
|
||
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:
|
||
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 herbicides.
|
||
x Avoid making more than two applications of this product 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, such as 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:
|
||
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).
|
||
|
||
Q5Z / Steadfast Q / MSTR /Notification with edits / 03-20-23 Page 13
|
||
|
||
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 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.
|
||
|
||
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
|
||
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.
|
||
|
||
WHEN TO APPLY
|
||
|
||
Timing to Crop
|
||
|
||
Apply SteadfastSTEADFAST® Q to corn that is up to 20 inches tall and exhibiting up to and including 6
|
||
leaf-collars. DO NOT apply to corn taller than 20 inches or exhibiting more than 6 leaf collars, whichever
|
||
is more restrictive. Some State and corn hybrid restrictions apply (see below). Not all
|
||
SteadfastSTEADFAST® Q tank mixtures may be applied to corn that is beyond 12" tall. Consult TANK
|
||
MIX APPLICATIONS for more information.
|
||
|
||
While SteadfastSTEADFAST® 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.
|
||
|
||
Apply SteadfastSTEADFAST® Q to field corn hybrids with a relative maturity (RM) rating of 77 days or
|
||
more, including "food grade" (yellow dent, hard endosperm), waxy and oil corn. Not all field corn hybrids
|
||
of less than 77 days RM, not all white corn hybrids nor Hi-Lysine hybrids have been tested for crop
|
||
safety, nor does DuPont Corteva Agriscience have access to all seed company data. Consequently,
|
||
injury arising from the use of SteadfastSTEADFAST® Q on these types of corn is the responsibility of the
|
||
user. Consult with your seed supplier before applying SteadfastSTEADFAST® Q to any of these corn
|
||
types. Applications of SteadfastSTEADFAST® Q to corn hybrids of 77-88 CRM must be limited to corn
|
||
that is 12” tall, less than or equal to 5-leaf collars, whichever is most restrictive. In addition, the application
|
||
of tank mixtures with dicamba-containing herbicides to 77-88 CRM corn must contain no more than 2
|
||
ounces active ingredient per acre of dicamba. Seed company publications indicate " DO NOT use"
|
||
notations for the use of some ALS herbicides on corn hybrids. As noted in the seed company
|
||
publications, DuPont Corteva Agriscience sulfonylurea herbicides such as SteadfastSTEADFAST® Q

|
||
|
||
SPRAY ADJUVANTS
|
||
|
||
Applications of SteadfastSTEADFAST® Q must include either a crop oil concentrate, modified seed oil or
|
||
a nonionic surfactant. In addition, an ammonium nitrogen fertilizer must be used unless specifically
|
||
prohibited by tank mix partner labeling.
|
||
|
||
Crop oil concentrate/modified seed oil plus ammonium nitrogen fertilizer is the preferred adjuvant system
|
||
for SteadfastSTEADFAST® Q.
|
||
|
||
Consult local DuPont company fact sheets, technical bulletins, and service policies prior to using other
|
||
adjuvant systems. If another herbicide is tank mixed with SteadfastSTEADFAST® Q, select adjuvants
|
||
authorized for use with both products. Products must contain only EPA-exempt ingredients (40 CFR
|
||
1001).
|
||
|
||
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 quart per 100 gallons spray solution) or 0.5% under arid conditions.
|
||
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 quarts/acre of a high-quality urea ammonium nitrate (UAN), including 28%N or 32%N, or 2
|
||
pounds/acre of a spray-grade ammonium sulfate (AMS). Use 4 quarts/acre UAN or 4 pounds/acre
|
||
AMS under arid conditions.
|
||
x DO NOT use liquid nitrogen fertilizer as the total carrier solution.
|
||
|
||
Special Adjuvant Types
|
||
|
||
x Combination adjuvant products may be used at doses that provide the required amount of NIS, COC,
|
||
MSO and/or ammonium nitrogen fertilizer. Consult product literature for use rates and restrictions.
|
||
x In addition to the adjuvants specified above, other adjuvant types may be used if they provide the
|
||
same functionality. Consult separate DuPont company technical bulletins for detailed information
|
||

MIXING INSTRUCTIONS
|
||
|
||
1. Fill the tank 1/4 to 1/3 full of water.
|
||
2. While agitating, add the required amount of SteadfastSTEADFAST® Q.
|
||
3. Continue agitation until the SteadfastSTEADFAST® Q is fully dispersed, at least 5 minutes.
|
||
4. Once the SteadfastSTEADFAST® Q is fully dispersed, maintain agitation and continue filling tank
|
||
with water. Thoroughly mix SteadfastSTEADFAST® Q with water before adding any other material.
|
||
5. As the tank is filling, add the required spray adjuvants (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 SteadfastSTEADFAST® Q spray mixture within 24 hours of mixing to avoid product
|
||
degradation.
|
||
8. If SteadfastSTEADFAST® Q and a tank mix partner are to be applied in multiple loads, pre-slurry the
|
||
SteadfastSTEADFAST® Q in clean water prior to adding to the tank. This will prevent the tank mix
|
||
partner from interfering with the dissolution of the SteadfastSTEADFAST® Q.
|
||
|
||

SteadfastSTEADFAST® Q may be tank mixed with full or reduced rates of preemergence grass
|
||
herbicides labeled for early postemergence application to field corn (including Keystone ® NXT,
|
||
CINCHCinch® ATZ, Resicore®, SureStart® II and Surpass® NXT) for increased residual activity of later-
|
||
emerging flushes of grasses such as smooth and large crabgrass. Application must be made before the
|
||
crabgrass emerges and before other grass weeds on the SteadfastSTEADFAST® Q label exceed their
|
||
labeled sizes.
|
||
|
||
For Additional Control of Broadleaf Weeds
|
||
|
||
SteadfastSTEADFAST® Q may be tank mixed with 0.5 to 0.75 fluid ounces per acre of topramezone (2.8
|
||
lb ai per gallon) plus atrazine at 0.375 to 1.5 pounds active per acre for improved burndown or residual
|
||
control of several broadleaf weeds including waterhemp, common ragweed, common lambsquarters, and
|
||

per acre, the use of methylated seed oil is advised. Refer to the topramezone product label for additional
|
||
information regarding application timing, tank mixtures, adjuvants, and rotational crops.
|
||
|
||
The use of nonionic surfactant is advised in place of crop oil concentrate for tank mixtures with
|
||
preemergence grass herbicides where applications are made early postemergence to small weeds.
|
||
|
||
When tank mixing SteadfastSTEADFAST® Q with EC formulated preemergence grass herbicides such
|
||
as s-metolachlor, DO NOT add mesotrione herbicide to the tank mixture. When other formulations of
|
||
preemergence grass herbicides are tank mixed with SteadfastSTEADFAST® Q + mesotrione
|
||
(CINCHCinch® ATZ), limit preemergence herbicide rates to no more than 2/3 the preemergence rates.
|
||
Always add nonionic surfactant in place of crop oil concentrate, and limit broadleaf weed sizes to less
|
||
than or equal to 4” tall.
|
||
|
||
Tank mixes of SteadfastSTEADFAST® Q and preemergence grass and broadleaf herbicides must be
|
||
applied postemergence to field corn before the crop exceeds the heights listed on the preemergence
|
||
herbicide label. Refer to the preemergence herbicide label for complete postemergence application
|
||
information, rates, and restrictions.
|
||
|
||

|
||
|
||
x The tank mix product is labeled for the same timing, method of application, adjuvants, and use
|
||
restrictions as SteadfastSTEADFAST® Q.
|
||
x The tank mixture is not specifically prohibited on the label of the tank mix product.
|
||
x The tank mix combination is compatible as determined by a “jar test” described in the TANK MIX
|
||
COMPATIBILITY TESTING section below.
|
||
|
||
|
||
|
||
Tank Mixing Precautions:
|
||
|
||
x Weed control and crop response with tank mixtures not specifically advised in this label are the
|
||
responsibility of the user and manufacturer of the tank mix product.
|
||
x Read and follow all applicable use directions, precautions, and limitations specified on the respective
|
||
product labels and fact sheets.
|
||
x A corn plant's predisposition to develop fused tissue emerging from the whorl (rattail) after the V11
|
||
stage may increase when a product containing dicamba is applied to small corn under early stressful
|
||
conditions. Be aware of this when applying tank mixes with dicamba to small corn (V3 stage or
|
||
smaller) under stressful conditions. See ENVIRONMENTAL CONDITIONS for a description of these
|
||
stressful conditions.
|
||
|
||
TANK MIX COMPATIBILITY TESTING
|
||
|
||
Perform a jar test prior to tank mixing to ensure compatibility of SteadfastSTEADFAST® Q and other
|
||
pesticides. Use a clear glass 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, sludges, gels, oily film or layers, or other precipitates, it is
|
||
not compatible and the tank mix combination cannot be used.
|
||
|
||
SEQUENTIAL APPLICATIONS WITH ACCENT® Q
|
||
|
||
Apply ACCENTAccent® Q herbicide 14 or more days after SteadfastSTEADFAST® Q applications to
|
||
control grasses that may emerge later in the year. Refer to the ACCENTAccent® Q label for grass species
|
||
controlled, proper size of weeds, rates, corn sizes, and other information. When following a
|
||
SteadfastSTEADFAST® Q application, DO NOT use more than 1.1 ounces (0.037 lb ai/acre) of
|
||
ACCENTAccent® Q per acre .
|
||
|
||
A sequential application of ACCENTAccent® Q will affect crop rotation intervals to certain sensitive crops,
|
||
including sugarbeets. For maximum crop rotation flexibility, consult the CROP ROTATION section before
|
||
applying ACCENTAccent® Q to fields previously treated with SteadfastSTEADFAST® Q.
|
||
|
||
CULTIVATION
|
||
|
||
A timely cultivation may be necessary to control suppressed weeds, or weeds that emerge after an
|
||
application of SteadfastSTEADFAST® Q in the absence of an activating rainfall.
|
||
|
||
Optimum timing for cultivation is 7–14 days after SteadfastSTEADFAST® Q application or upon seeing
|
||
the establishment of new weeds.
|
||
|
||
ENVIRONMENTAL CONDITIONS AND BIOLOGICAL ACTIVITY
|
||
|
||
SteadfastSTEADFAST® Q provides best results when applied to young, actively growing weeds.
|
||
Applications made during warm, moist conditions (70°F or more) and adequate soil moisture both before
|
||
and after application maximizes performance.

Q5Z / Steadfast Q / MSTR /Notification with edits / 03-20-23 Page 21
|
||
|
||
The degree and duration of control depend on spray coverage, activating rainfall, weed spectrum, weed
|
||
size, growing conditions before and after treatment, soil moisture, and adjuvant selection.
|
||
Adequate soil moisture is required for optimum activity. Rainfall within 5-7 days will enhance
|
||
SteadfastSTEADFAST® Q residual activity. A timely cultivation may be required for maximum weed
|
||
control without an activating rain.
|
||
|
||
SteadfastSTEADFAST® Q is rainfast in 4 hours.
|
||
|
||
Treating weeds that exceed maximum label height or that are under stress may result in incomplete
|
||
control. Poor weed control or crop injury may result from applications made to plants under stress from:
|
||
|
||
x abnormally hot or cold weather
|
||
x environmental conditions such as drought, water-saturated soils, hail damage, or frost
|
||
x disease, insect, or nematode injury
|
||
x prior herbicide, or carryover from a previous year’s herbicide application
|
||
|
||
Severe stress from conditions immediately following application may also result in crop injury or poor
|
||
weed control. Stress affects all weeds, but especially weeds such as woolly cupgrass, green and yellow
|
||
foxtail, and wild proso millet.
|
||
|
||
If the corn or grass weeds are under stress, delay application until stress passes and both weeds and
|
||
corn resume active growth.
|
||
|
||
Apply SteadfastSTEADFAST® Q when minimum nighttime temperatures are above 40°F and the
|
||
maximum daytime temperatures are below 92°F to maximize performance and minimize the potential for
|
||
crop injury.
|
||
|
||
Applications made during or immediately following periods of large day/night temperature fluctuations or
|
||
where daytime temperatures DO NOT exceed 50°F may decrease weed control and increase the
|
||
potential for crop injury.
|
||
|
||
SteadfastSTEADFAST® Q rapidly inhibits the growth of susceptible weeds, reducing weed competition
|
||
within as little as 6 hours after application. Susceptible plants are controlled in 7–21 days.

|
||
|
||
SOIL INSECTICIDE INTERACTION INFORMATION
|
||
|
||
Before using SteadfastSTEADFAST® Q, ensure that it is compatible with any other insecticides
|
||
previously applied to the corn crop.
|
||
|
||
SteadfastSTEADFAST® Q 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.
|
||
|
||
SteadfastSTEADFAST® Q may be applied to corn previously treated with chlorethoxyfox, chlorethoxyfos
|
||
+ bifenthrin, tebupirimphos + cyfluthrin, tefluthrin insecticides or non-organophosphate (OP) soil
|
||
insecticides regardless of soil type.
|
||
|
||
DO NOT tank mix SteadfastSTEADFAST® Q with foliar-applied organophosphate insecticides including
|
||
chlorpyrifos or malathion, as severe crop injury may occur. To avoid crop injury or antagonism, apply
|
||
these products at least seven days before or 3 days after the application of SteadfastSTEADFAST® Q.
|
||
|
||
DO NOT apply SteadfastSTEADFAST® Q within 45 days of crop emergence where the organophosphate
|
||
insecticide terbufos was applied since corn crop injury may occur. Applications made to corn previously

||
|
||
Q5Z / Steadfast Q / MSTR /Notification with edits / 03-20-23 Page 22
|
||
|
||
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.
|
||
|
||
Applications of SteadfastSTEADFAST® Q to corn previously treated with terbufos, chlorpyrifos or phorate
|
||
may cause unacceptable crop injury, especially on soils of less than 4% organic matter.
|
||
|
||
CROP ROTATION
|
||
|
||
Rotational crops vary in their response to low concentrations of SteadfastSTEADFAST® Q remaining in the
|
||
soil. SteadfastSTEADFAST® Q dissipates rapidly in warm, acidic, microbiologically active soils.
|
||
|
||
The amount of SteadfastSTEADFAST® Q which may be present in the soil depends on soil pH and organic
|
||
matter content, elapsed time since application, crop production practices, and environmental factors.
|
||
|
||
Injury to rotational crops may occur in high-pH, cold soils if dry weather prevails between application and
|
||
rotational crop planting.
|
||
|
||
For fields treated with sequential applications of SteadfastSTEADFAST® Q and ACCENTAccent
|
||
® Q herbicide,
|
||
consult the crop rotation intervals listed on the ACCENTAccent® Q and SteadfastSTEADFAST® Q labels. Use
|
||
the most restrictive recrop interval from either label.
|
||
|
||
The following rotational intervals must be observed when using SteadfastSTEADFAST® Q:

* Except the sweet corn varieties “Merit”, “Carnival”, and “Sweet Success”, for which the minimum time interval is 15 months.
|
||
|
||
**Rotational intervals need to 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.
|
||
|
||
† On sprinkler irrigated fields in Idaho, Utah, and Northern Nevada it is best to use deep fall tillage such as plowing prior to planting
|
||
alfalfa. Product degradation may be less on furrow irrigated soils and may result in some crop injury.

|
||
APPLICATION INFORMATION
|
||
|
||
GROUND APPLICATION
|
||
|
||
Broadcast Application
|
||
|
||
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
|
||
|
||
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.
|
||
|
||
Band Application
|
||
|
||
For band applications, use proportionately less spray mixture. To avoid crop injury, carefully calibrate the
|
||
band applicator to not exceed the labeled rate. Carefully follow the manufacturer’s instructions for nozzle
|
||
type (flat fans), orientation, distance of nozzles from the crop and weeds, spray volumes, calibration and
|
||
spray pressure.
|
||
|
||
AERIAL APPLICATION
|
||
|
||
Aerial application is not permitted in New York State or California.
|
||
|
||
Use nozzle types and arrangements that will provide optimum spray distribution and maximum coverage
|
||
at a minimum of 5 GPA.
|
||
|
||
SPRAYER PREPARATION/CLEANUP
|
||
|
||
It is important that spray equipment is clean and free of previous pesticide deposits before using
|
||
SteadfastSTEADFAST® Q and then properly cleaned out following application. Clean all application
|
||
equipment before applying SteadfastSTEADFAST® 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 SteadfastSTEADFAST® Q, thoroughly clean all mixing and
|
||
spray equipment to avoid subsequent crop injury.
|
||
|
||
Note:
|
||
|
||
x When cleaning spray equipment before applying SteadfastSTEADFAST® Q, 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.

|
||
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.
|
||
