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).

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 FIFRA and is subject to review by the Agency. If the

|
||
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.
|
||
|
||
If these conditions are not complied with, the registration will be subject to cancellation in accordance
|
||
with FIFRA section 6. Your release for shipment of the product constitutes acceptance of these

|
||
|
||
Page 6
|
||
|
||
|
||
2.2 Personal Protective Equipment (PPE)
|
||
All mixers, loaders, applicators, and other handlers must wear:
|
||
• Protective eyewear
|
||
• Long-sleeved shirt and long pants
|
||
• Chemical-resistant gloves made of barrier laminate, nitrile rubber ≥14 mils, neoprene
|
||
rubber ≥14 mils, or Viton™ ≥14 mils
|
||
• Shoes plus socks
|
||
|
||
Discard clothing and other absorbent materials that have been drenched or heavily
|
||
contaminated with this product. DO NOT reuse them.
|
||
2.3 User Safety Requirements
|
||
Follow manufacturer's instructions for cleaning/maintaining PPE. If no such instructions for
|
||
washables exist, use detergent and hot water. Keep and wash PPE separately from other
|
||
laundry.
|
||
|
||
2.4 Engineering Controls
|
||
When handlers use closed systems, enclosed cabs, or aircraft in a manner that meets the
|
||
requirements listed in the Worker Protection Standard (WPS) for agricultural pesticides (40
|
||
CFR 170.607(d-f)), the handler PPE requirements may be reduced or modified as specified in
|
||
the WPS. Mixers and loaders supporting aerial applications are required to use closed
|
||
systems. The closed system must be used in a manner that meets the requirements listed in
|
||
the Worker Protection Standard (WPS) for agricultural pesticides (40 CFR 170.607(d)). When
|
||
using the closed system, the mixers’ and loaders’ PPE requirements may be reduced or
|
||
modified as specified in the WPS.
|
||
2.5 User Safety Recommendations
|
||
User Safety Recommendations
|
||
Users should:
|
||
• Wash hands thoroughly with soap and wate r after handling and before eating,
|
||
drinking, chewing gum, using tobacco, or using the toilet.
|
||
• Remove clothing/PPE immediately if pes ticide gets inside. Then wash thoroughly
|
||
and put on clean clothing.
|
||
• 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.
|
||
|

|
||
|
||
2.6 Environmental Hazards
|
||
This pesticide is toxic to marine/estuarine invertebrates. DO NOT apply directly to water, to
|
||
areas where surface water is present or to intertidal areas below the mean high water mark.
|
||
Drift and runoff may be hazardous to terrestrial and aquatic plants in neighboring areas. DO
|
||
NOT contaminate water when disposing of equipment washwaters or rinsate.
|
||
2.6.1 Groundwater Advisory
|
||
S-metolachlor and Sulfentrazone are known to leach through soil into groundwater under
|
||
certain conditions as a result of label use. These chemicals may leach into groundwater if
|
||
used in areas where soils are permeable, particularly where the water table is shallow.
|
||
2.6.2 Surface Water Advisory
|
||
|
||
This product may impact surface water quality due to spray drift and 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. These include poorly draining or wet soils with readily visible slopes
|
||
toward adjacent surface waters, frequently flooded areas, areas overlying extremely shallow
|
||
groundwater, areas with in-field canals or ditches that drain to surface water, areas not
|
||
separated from adjacent surface waters with vegetated filter strips, and areas over-lying tile
|
||
drainage systems that drain to surface waters. A level, well-maintained vegetative buffer strip
|
||
between areas to which this product is applied and surface water features such as ponds,
|
||
streams, and springs will reduce the potential loading of S-metolachlor and Sulfentrazone
|
||
from runoff water and sediment. Runoff of this product will be reduced by avoiding
|
||
applications when rainfall or irrigation is expected to occur within 48 hours.
|
||
|
||
DO NOT use on coarse soils classified as sand, which have less than 1% organic
|
||
matter.
|
||
|
||
2.6.3 Non-target Organism Advisory
|
||
This product is toxic to plants and may adversely impact the forage and habitat of non-target
|
||
organisms, including pollinators, in areas adjacent to the treated site. Protect the forage and
|
||
habitat of non-target organisms by following label directions intended to minimize spray drift.
|
||
|
||
2.6.4 Reporting Ecological Incidents
|
||
To report ecological incidents, including mortality, injury, or harm to plants and animals, call
|
||
1-800-888-8372.
|
||
|
||
2.6.5 Mixing/Loading/Application Instructions
|
||
|
||
Care must be taken when using this product to prevent back-siphoning into wells, spills or
|
||
improper disposal of excess pesticide, spray mixtures, or rinsates. Check-valves or
|
||
antisiphoning devices must be used on all mixing and/or irrigation equipment.
|
||
|
||
Page 8
|
||
|
||
• This product may not be mixed or loaded withi n 50 feet of any wells (including abandoned
|
||
wells and drainage wells), sinkholes, perennial or intermittent streams and rivers, and
|
||
natural or impounded lakes and reservoirs.
|
||
o This setback does not apply to proper ly capped or plugged abandoned wells and
|
||
does not apply to impervious pads or properly diked mixing/loading areas.
|
||
• Operations that involve mixing, loading, rinsi ng, or washing of this product into or from
|
||
pesticide handling or application equipment or containers within 50 ft of any well are
|
||
prohibited, unless conducted on an impervious pad constructed to withstand the weight of
|
||
the heaviest load that may be positioned on or moved across the pad.
|
||
o Such a pad shall be designed and maintained to contain any product spills or
|
||
equipment leaks, container or equipment rinse or wash water, and rain water that
|
||
may fall on the pad.
|
||
o Surface water shall not be allowed to either flow over or from the pad, which means
|
||
the pad must be self-contained.
|
||
o The pad shall be sloped to facilitate material removal.
|
||
o An unroofed pad shall be of sufficient capac ity to contain at a minimum 110% of
|
||
the capacity of the largest pesticide container or application equipment on the pad.
|
||
o A pad that is covered by a roof of sufficient size to completely exclude precipitation
|
||
from contact with the pad shall have a minimum containment capacity of 100% of
|
||
the capacity of the largest pesticide container or application equipment on the pad.
|
||
• Containment capacities as described abov e shall be maintained at all times.
|
||
|
||
The above specific minimum containment capacities DO NOT apply to vehicles when
|
||
delivering pesticide shipments to the mixing/loading site. States may have in effect additional
|
||
requirements regarding wellhead setbacks and operational containment.
|
||
|
||
Product must be used in a manner that will prevent back siphoning in wells, spills or
|
||
improper disposal of excess pesticide, spray mixtures or rinsates.
|
||
|
||

3.0 PRODUCT INFORMATION
|
||
A24561 Herbicide is a soil-applied herbicide for the control of susceptible broadleaf, grass
|
||
and sedge weeds. If adequate moisture (1/2" to 1") from rainfall or irrigation is not received
|
||
within 7 to 10 days after the A24561 Herbicide treatment, a shallow incorporation (less than
|
||
2”), may be needed to obtain desired weed control. When activating moisture is not received
|
||
a planned post-emergence application of a labeled herbicide will be needed for optimum
|
||
weed control. If an activating rainfall (½” to 1”) is not received A24561 Herbicide will provide a
|
||
reduced level of control of susceptible germinating weeds.
|
||
|
||
Under normal growing conditions, A24561 Herbicide exhibits excellent crop safety. Soil
|
||
applications of A24561 Herbicide must be made before crop seed germination to prevent
|
||
injury to the emerging crop seedlings. A24561 Herbicide applied after crop emergence will
|
||
cause severe injury to the crop. Poor growing conditions, such as excessive soil moisture,
|
||
cool temperatures, and soil compaction or the presence of various pathogens may impact
|
||
|
||
Page 10
|
||
|
||
seedling vigor. Under these conditions, the active ingredients in A24561 Herbicide can
|
||
contribute to crop response.
|
||
|
||
Mechanism of Action
|
||
Following the application of A24561 Herbicide to soil, germinating seeds and seedlings take
|
||
up A24561 Herbicide from the soil solution. The amount of A24561 Herbicide in soil solution
|
||
available for weed uptake is determined primarily by soil type, soil organic matter and soil pH.
|
||
Similar to other herbicides, A24561 Herbicide adsorbs to the clay and organic matter (OM)
|
||
fractions of soils; effectively limiting the amount of active ingredient immediately available to
|
||
control weeds.
|
||
|
||
Influence of soil type, organic matter and pH on A24561 Herbicide use rates and crop
|
||
response
|
||
|
||
Coarse textured and high pH >7.2 soils (see Section 9.0) will exhibit increased weed control
|
||
and crop response with A24561 Herbicide. It is important to know the soil type and soil pH
|
||
levels of the field (or areas within a field) before application to determine the proper rate of
|
||
A24561 Herbicide for the crop. Soil organic matter content and soil pH can vary widely and
|
||
independently of soil type and requires an accurate analysis of representative soil samples or
|
||
grids of soil samples within a specific field to determine its content.
|
||
|
||
It is important to note that irrigation with highly alkaline water (high pH) following a A24561
|
||
Herbicide soil application can also significantly increase the amount of A24561 Herbicide
|
||
available in the soil solution. Irrigation with water having a pH greater than 7.2 could result in
|
||
adverse crop response. This response will ultimately depend on initial A24561 Herbicide
|
||
application rate, timing, amount and pH of irrigation water and sensitivity of the crop and its
|
||
growth stage when irrigated. The risk of adverse crop response will lessen with the advance
|
||
in growth stage among most crops.
|
||
3.1 Weed Resistance Management
|
||
|
||
For resistance management, please note that A24561 Herbicide contains both a Group 14
|
||
(Sulfentrazone) and a Group 15 (S-Metolachlor) herbicide. Any weed population may contain
|
||
plants naturally resistant to Group 14 and/or Group 15 herbicides. The resistant individuals
|
||
may dominate the weed population if these herbicides are used repeatedly in the same fields.
|
||
Appropriate resistance-management strategies should be followed. Selection of resistant
|
||
biotypes, through repeated use of these herbicides in the same field or lower than labeled
|
||
use rates, may result in weed control failures. If resistance is suspected, contact your local
|
||
Syngenta representative and/or agricultural advisor for assistance.
|
||
|
||
3.1.1 Principles of Herbicide Resistant Weed Management
|
||
Scout and know your field
|
||
• Know weed species present in the fi eld to be treated through scouting and field
|
||
history. An understanding of weed biology is useful in designing a resistance
|
||
management strategy. Ensure the weed management program will control all weeds
|
||
present.
|
||
|
||
Page 11
|
||
|
||
• Fields should be scouted prior to application to determine species present and growth
|
||
stage. Always apply this herbicide at the full labeled rate and correct timing for the
|
||
weeds present in the field.
|
||
|
||
Utilize non-herbicidal practices to add diversity
|
||
• Use diversified management tactics such as cover crops, mechanical weed control,
|
||
harvest weed seed control, and crop rotation as appropriate.
|
||
Use good agronomic practices, start clean and stay clean
|
||
• Use good agronomic practices t hat enhance crop competitiveness.
|
||
• Plant into weed-free fields utilizing tillage or an effective burndown herbicide for control
|
||
of emerged weeds.
|
||
• Sanitize farm equipment to avoid spreading seed or vegetative propagules prior to
|
||
leaving fields.
|
||
Difficult to control weeds
|
||
• Fields with difficult to control weeds shoul d be planted in rotation with crops that allow
|
||
the use of herbicides with an alternative mode of action or different management
|
||
practices.
|
||
• Difficult to control weeds may require sequential applications, such as a broad
|
||
spectrum preemergence herbicide followed by one or more postemergence herbicide
|
||
applications. Utilize herbicides containing different modes of action effective on the
|
||
target weeds in sequential applications.
|
||
Do not overuse the technology
|
||
• Do not use this or any other herbicide wit h the same mode of action in a single
|
||
growing season unless mixed with an herbicide with a different mode of action which
|
||
provides overlapping spectrum for difficult to control weeds.
|
||
Scout and inspect fields following application
|
||
• Prevent an influx of weeds into the fi eld by controlling weeds in field borders.
|
||
• Scout fields after application to veri fy that the treatment was effective.
|
||
|
||
• Suspected- herbicide resistant weeds may be identified by these indicators
|
||
• Failure to control a weed species norma lly controlled by the herbicide at the
|
||
dose applied, especially if control is achieved on adjacent weeds;
|
||
• A spreading patch of non-controlled plan ts of a particular weed species; and
|
||
• Surviving plants mixed with controlled individuals of the same species.
|
||
|
||
Page 12
|
||
|
||
• Report non-performance of this produc t to your Syngenta retailer, Syngenta
|
||
representative, or call 1-866-Syngent(a) (866-796-4368). If resistance is suspected,
|
||
ensure weed escapes are controlled using an herbicide with an effective mode of
|
||
action and/or use non-chemical means to prevent further seed production.
|
||
|
||
Prevent weed escapes before, during, and after harvest
|
||
• Do not allow weed escapes to produce seed or vegetative structures such as tubers or
|
||
stolons which contribute to spread and survival. Consider harvest weed seed
|
||
management and control weeds postharvest to prevent seed production.
|
||
Resistant Weeds
|
||
• Contact your local Syngenta r epresentative, retailer, crop advisor, or extension agent
|
||
to determine if weeds resistant to this mode of action are present in your area. If
|
||
resistant biotypes have been reported, use the full labeled rate of this product, apply at
|
||
the labeled timing, and tank-mix with a different mode of action product so there are
|
||
multiple effective modes of application for each suspected resistant weed.

|
||
4.4.2 Tank-Mix Precautions
|
||
• It is the pesticide user’s responsibility to ens ure that all products are registered for the
|
||
intended use. Read and follow the applicable restrictions, limitations, and directions for
|
||
use on all product labels involved in tank mixing. User must follow the most restrictive
|
||
directions for use and precautionary statements of each product in the tank mixture.
|
||
• Users must follow the most restrictive dire ctions for use and precautionary statements of
|
||
each product in the tank mixture.
|
||
• For tank mixtures with wett able powder or dry flowable formulations, use screens and
|
||
strainers no finer than 50-mesh.
|
||
• Check compatibility ( Section 4.4.3) with other pesticides and/or liquid fertilizers before
|
||
mixing in spray tank.
|
||
|
||
Page 14
|
||
|
||
|
||
4.4.3 Tank-Mix Compatibility
|
||
• Conduct a jar test using a 1 pt to 1 qt cont ainer with lid by adding water or other intended
|
||
carrier such as a liquid fertilizer to the jar.
|
||
• Next, add the appropriate amount of pesticide(s) or tank-mix partner(s) in their relative
|
||
proportions based on recommended label rates. Add tank-mix components separately in
|
||
the order described in the tank-mixing section, Section 4.4.4. After each addition, shake
|
||
or stir gently to thoroughly mix.
|
||
• After all ingredients have been added, put the lid on the jar, tighten and invert the jar 10
|
||
times to mix.
|
||
• After mixing, let the mixture stand 15–30 minutes and then examine for signs of
|
||
incompatibility such as obvious separation, large flakes, precipitates, gels, or heavy oily
|
||
film on the jar.
|
||
• If the mixture remains mixed or can be remixed readily, it is physically compatible and can
|
||
be used.
|
||
• If the mixture is incompatib le, repeat the test using a compatibility agent at the
|
||
recommended rate. Or, if applicable, slurry dry formulations in water before adding to the
|
||
jar. If incompatibility is still observed after following these procedures, do not use the
|
||
mixture.
|
||
• After compatibility testing is complete, dispose of any pesticide wastes in accordance with
|
||
the storage and disposal section, Section 10.0, of this label.
|
||
|
||

4.5 Dry Bulk Fertilizers
|
||
A24561 Herbicide may be applied impregnated on dry fertilizers. When applied as directed
|
||
with adequate soil coverage, A24561 Herbicide dry bulk fertilizer mixtures will provide
|
||
satisfactory weed control.
|
||
Follow all A24561 Herbicide label directions regarding product use rates per acre, registered
|
||
crops, incorporation, special instructions and precautions. Apply A24561 Herbicide/dry
|
||
fertilizer mixtures with ground equipment only. All individual state regulations relating to dry
|
||
bulk fertilizer blending, registration, labeling, and application are the responsibility of the
|
||
individual and/or company preparing, storing, transporting, selling, or applying the A24561
|
||
Herbicide/dry fertilizer mixture.
|
||
4.5.1 Preparation of Dry Herbicide/Fertilizer Mixtures
|
||
• Use any closed drum, belt, ribbon, or other commonly used dry bulk fertilizer blender.
|
||
• Prepare a slurry of A24561 Herbicide in a clean container using clear water.
|
||
• Slowly add the A24561 Herbicide/water slurry to the impregnation spray tank and finish
|
||
filling as needed with clear water.
|
||
• Place the nozzles used to spray A24561 He rbicide and A24561 Herbicide mixtures onto
|
||
the fertilizer in such a way as to provide uniform spray coverage.
|
||
• The A24561 Herbicide dry bulk fertilizer mi xture must be spread uniformly on the soil
|
||
surface.
|
||
• Uneven spreading leaving untreated areas c an cause poor weed control or overlapping
|
||
areas with potential increased A24561 Herbicide use rates could result in possible crop
|
||
response.
|
||
• A minimum of 200 pounds of dry bulk fert ilizer impregnated with the listed amount of
|
||
A24561 Herbicide must be applied per acre to achieve adequate soil coverage for
|
||
satisfactory weed control.
|
||
• Refer to Section 9.0 to determine the rate of A24561 Herbicide to be applied per acre.
|
||
• Calculate amounts of A24561 Herbicide by the following formula:
|
||
|
||
2000 A24561 Herbicide use rate fluid ounces of A24561 Herbicide
|
||
------------------- x in fluid ounces per acre = to be applied per
|
||
Pounds dry fertilizer ton of fertilizer
|
||
per acre
|
||
|
||
|
||
4.5.2 Precautions
|
||
• To avoid crop injury, do not use the herbici de/fertilizer mixture on crops where bedding
|
||
occurs.
|
||
• DO NOT impregnate A24561 Herbicide with ammonium nitrate, potassium nitrate, or
|
||
sodium nitrate either alone or in blends with other fertilizers because these materials will
|
||
not absorb the herbicide.
|
||
• DO NOT use A24561 Herbicide alone or in mixtures on straight limestone, since
|
||
absorption will not be achieved.
|
||
|
||
Page 16
|
||
|
||
4.5.3 Application Instructions
|
||
• Apply 200-450 lb of the herbici de/fertilizer mixture per acre.
|
||
• For best results, apply the mi xture uniformly to the soil with properly calibrated equipment
|
||
immediately after blending.
|
||
• Uniform application of the herbi cide/fertilizer mixture is essential to prevent possible crop
|
||
injury.
|
||
• Non-uniform application may also result in unsatisfactory weed control. In areas where
|
||
conventional tillage is practiced, a shallow incorporation of the mixture into the soil may
|
||
improve weed control.
|
||
• On fine- or medium textured soils in areas where soil incorporation is not planned, i.e.,
|
||
reduced tillage situations or in some conventional till situations, make applications
|
||
approximately 30 days before planting to allow moisture to move the herbicide/fertilizer
|
||
mixture into the soil.
|
||
• On coarse textured soils, make applicati ons approximately 14 days prior to planting.
|
||
|
||
4.6 Application through Irrigation Systems (Chemigation)
|
||
4.6.1 Chemigation Restrictions

|
||
|
||
|
||
4.6.2 Operating Instructions For Chemigation
|
||
1. The system must contain a functional check-va lve, vacuum relief valve, and low pressure
|
||
drain appropriately located on the irrigation pipeline to prevent water-source
|
||
contamination from backflow.
|
||
2. The pesticide injection pipeline must contai n a functional, automatic, quick-closing check-
|
||
valve to prevent the flow of fluid back toward the injection pump.
|
||
3. The pesticide injection pipeline must also contain a functional, normally closed, solenoid-
|
||
operated valve located on the intake side of the injection pump and connected to the
|
||
system interlock to prevent fluid from being withdrawn from the supply tank when the
|
||
irrigation system is either automatically or manually shut down.
|
||
4. The system must contain functional interlo cking controls to automatically shut off the
|
||
pesticide injection pump when the water pump motor stops.
|
||
5. The irrigation line or water pump must include a functional pressure switch which will stop
|
||
the water pump motor when the water pressure decreases to the point where pesticide
|
||
distribution is adversely affected.
|
||
|
||
Page 17
|
||
|
||
6. Systems must use a metering pump, such as a positive displacement injection pump
|
||
(e.g., diaphragm pump or piston pump), effectively designed and constructed of materials
|
||
that are compatible with pesticides and capable of being fitted with a system interlock.
|
||
7. Do not apply when wind speed favors dr ift beyond the area intended for treatment.
|
||
|
||
4.6.3 Specific Instructions For Public Water Systems
|
||
1. Public water system means a system for t he provision to the public of piped water for
|
||
human consumption if such system has at least 15 service connections or regularly
|
||
serves an average of at least 25 individuals daily at least 60 days out of the year.
|
||
2. Chemigation systems connec ted to public water systems must contain a functional,
|
||
reduced-pressure zone (RPZ), back-flow preventer or the functional equivalent in the
|
||
water supply line upstream from the point of pesticide introduction. As an option to the
|
||
RPZ, the water from the public water system should be discharged into a reservoir tank
|
||
prior to pesticide introduction. There shall be a complete physical break (air gap) between
|
||
the outlet end of the fill pipe and the top or overflow rim of the reservoir tank of at least
|
||
twice the inside diameter of the fill pipe.
|
||
3. The pesticide injection pipeline must contai n a functional, automatic, quick-closing check
|
||
valve to prevent the flow of fluid back toward the injection pump.
|
||
4. The pesticide injection pipeline must c ontain a functional, normally closed, solenoid-
|
||
operated valve located on the intake side of the injection pump and connected to the
|
||
system interlock to prevent fluid from being withdrawn from the supply tank when the
|
||
irrigation system is either automatically or manually shut down.
|
||
5. The system must contain functional interlo cking controls to automatically shut off the
|
||
pesticide injection pump when the water pump motor stops, or in cases where there is no
|
||
water pump, when the water pressure decreases to the point where pesticide distribution
|
||
is adversely affected.
|
||
6. Systems must use a metering pump, such as a positive displacement injection pump
|
||
(e.g., diaphragm pump) effectively designed and constructed of materials that are
|
||
compatible with pesticides and capable of being fitted with a system interlock.
|
||
7. Do not apply when wind speed favors dr ift beyond the area intended for treatment.
|
||
|
||
4.6.4 Application Directions For Irrigation Systems
|
||
1. Prepare a mixture with a mini mum of 1 part water to 1 part herbicide(s) and inject this
|
||
mixture into the center pivot system. Injecting a larger volume of a more dilute mixture
|
||
per hour will usually provide more accurate calibration of equipment.
|
||
2. Maintain sufficient agitation to keep the herbicide in suspension.
|
||
3. Meter into irrigation water duri ng entire period of water application.
|
||
4. Apply in ½-1 inch of water. Us e the lower water volume (½ inch) on coarser soils and the
|
||
higher volume (1 inch) on fine textured soils. More than 1 inch of water at application may
|
||
reduce weed control by moving the herbicide below the effective zone in the soil.
|
||
5. Apply immediately after planti ng unless specified differently in Section 9.0.
|
||

|
||
4.6.5 Center Pivot Irrigation Application
|
||
• A24561 Herbicide alone or in tank mixture with other herbicides on this label, which are
|
||
registered for center pivot application, may be applied in irrigation water preemergence
|
||
(after planting, but before weeds or crop emerge) at rates listed on this label.
|
||
• Follow all restrictions (height, timing, rate, etc.) to avoid illegal residues.
|
||
• Crop injury, lack of effectiveness, or illegal pe sticide residues in the crop can result from
|
||
non-uniform distribution of treated water.
|
||
• Where sprinkler distribution patterns do not overlap sufficiently, unacceptable weed
|
||
control may result. Where sprinkler distribution patterns overlap excessively, crop injury
|
||
may result.
|
||
|
||
4.7 Sprayer Cleanout
|
||
Thoroughly clean sprayer or other application device before using. Dispose of cleaning
|
||
solution in a responsible manner. Do not use a sprayer or applicator contaminated with any
|
||
other materials, or crop damage or clogging of the application device may result.
|
||

|
||
5.0 REPLANT AND ROTATIONAL CROPS
|
||
5.1 Replant and Rotational Crops
|
||
• If a crop treated with A24561 Herbicide is lost, any crop on this label, or on a
|
||
supplemental A24561 Herbicide label, may be replanted or rotated at any interval
|
||
provided that the rate of A24561 Herbicide applied to the previous crop was not greater
|
||
than the labeled rate for the crop to be replanted.
|
||
|
||
The crops listed in the table below may be planted at the specified interval following

|
||
5.2 Limited Water or Irrigation Conditions
|
||
When planting rotational crops, special attention must be given to the amount of rainfall and
|
||
type of irrigation used. Rotational crops listed on this label are safe for planting after a
|
||
A24561 Herbicide application provided the rotational interval is followed and the preceding
|
||
crop received natural rainfall or overhead irrigation.
|
||
When non-overhead watering methods (e.g. drip tape, furrow irrigation, etc.) are used, the
|
||
areas of the field not receiving water (e.g. furrows when drip irrigated or bed tops when
|
||
furrow irrigated) will have a higher A24561 Herbicide residue remaining in the soil resulting in
|
||
a significant increase in the rotational crop injury risk.
|
||
To reduce the risk of rotational crop injury, thoroughly incorporate the A24561 Herbicide
|
||
treated field to a depth of 3-4 inches before planting the rotational crop. For more thorough
|
||
incorporation, till the soil in 2 different directions (cross-till). Even with thorough tillage, injury
|
||
to rotational crops is still possible following non-overhead watering methods or limited
|
||
moisture conditions.
|
||
|
||
6.0 COVER CROPS
|
||
A cover crop can be an important tool for the overall farm cropping system. Cover crops are
|
||
planted for conservation purposes, soil erosion control, soil health improvement, water quality
|
||
improvement, and weed management. A cover crop can be a single crop or a combination of
|
||
crops, including grasses and/or broadleaf crops.
|
||
After harvest of a A24561 Herbicide treated crop, planting of a cover crop is allowed provided
|
||
the cover crop is not grazed or fed to livestock nor harvested for food. Terminate the cover
|
||
crop through natural causes such as frost or intentional termination by herbicide application,
|
||
crimping, rolling, tillage, or cutting.
|
||
All possible cover crops or cover crop combinations have not been tested for tolerance to this
|
||
product. Before planting the cover crop, determine the level of tolerance for the intended
|
||
cover crops by conducting a field bioassay. Refer to Section 6.1 for instructions on how to
|
||
conduct a field bioassay.
|
||
6.1 Field Bioassay for Cover Crops
|
||
A field bioassay is a method of determining if herbicide residues are present in the soil at
|
||
concentrations high enough to adversely affect crop growth.
|
||
|
||
Conduct the field bioassay by planting several strips of the desired cover crop across the field
|
||
which has been previously treated with A24561 Herbicide. Plant the cover crop strips
|
||
perpendicular to the direction of the product application. The strips should be located so that
|
||
all the different field conditions are encountered, including differences in field terrain, soil
|
||
texture, organic matter, pH, and drainage.
|
||
|
||
Page 21
|
||
|
||
If the cover crop does not show adverse effects such as crop injury and/or stand reduction,
|
||
the field can be planted to this cover crop. If injury and/or stand reduction are visible, wait
|
||
two to four weeks for further herbicide degradation to occur and repeat the bioassay.
|
||
Alternatively, select a different cover crop and repeat the bioassay. Only plant cover crops
|
||
that show acceptable tolerance in the field bioassay.
|
||
|
||
7.0 RESTRICTIONS AND PRECAUTIONS
|
||
7.1 Use Restrictions
|
||
• DO NOT apply when wind speed favors drift beyond the area intended for treatment.
|
||
• DO NOT apply under conditions which favor runoff or wind erosion of soil containing this
|
||
product to non-target areas. To prevent off-site movement due to runoff or wind erosion:
|
||
o Avoid treating powdery dry or light sand soils when conditions are favorable for
|
||
wind erosion. Under these conditions, the soil surface should first be settled by
|
||
rainfall or irrigation.
|
||
o DO NOT apply to impervious substrates, such as paved or highly compacted
|
||
surfaces.
|
||
o DO NOT use tailwater from the first flood or furrow irrigation of treated fields to treat
|
||
non-target crops, unless at least ½ inch of rainfall has occurred between
|
||
application and the first irrigation.
|
||
|
||
7.2 Use Precautions
|
||
• Avoid application under conditions which favo r runoff or wind erosion of soil containing
|
||
this product to non-target areas.
|
||
• Use of a sprayer or applicator contaminated with any other materials, may result in crop
|
||
damage or clogging of the application device.
|
||
• Avoid spray overlap, as crop injury may result.
|
||
• To avoid spray drift, avoid making applications under windy conditions.
|
||
• Injury may occur following the use of A24561 Herbicide under abnormally high soil
|
||
moisture conditions during early development of the crop.
|
||
• Dry weather following applicati on of A24561 Herbicide may reduce weed control. Cultivate
|
||
if weeds develop.
|
||
• To avoid crop injury, avoid the use of a her bicide/fertilizer mixture on crops where bedding
|
||
occurs.
|
||
• Avoid application to humans or animals. Flagmen and loaders must avoid inhalation of
|
||
spray mist and prolonged contact with skin.
|
||
|
||
7.3 Mandatory Spray Drift Management
|
||
Aerial Applications:
|
||
• Aerial application is allowed only when environmental conditions prohibit ground
|
||
application.
|
||
• When this product is allowed to be appl ied by air, applicator must use a
|
||
minimum finished spray volume of 5 gallons per acre.
|
||
|
||
Page 22
|
||
|
||
• DO NOT release spray at a height greater than 10 ft above the ground or
|
||
vegetative canopy, unless a greater application height is necessary for pilot
|
||
safety.
|
||
• Select coarse to very coarse droplet size (ASABE S641).
|
||
• Applicators may spray only when wi nd speed is between 3 and 10 mph.
|
||
• Applicators must use ½ swath displa cement upwind at the downwind edge of
|
||
the field.
|
||
• The boom length must be 75% or less of the wingspan for fixed-wing aircraft
|
||
and 90% or less of the rotor diameter for helicopters.
|
||
• DO NOT apply during temperature inversions.
|
||
|
||
Ground Boom Applications:
|
||
• Apply a minimum of 10 gallons of finished spray per acre by ground.
|
||
• DO NOT release spray at a height greater than 30 inches from the soil.
|
||
• Select medium to coarser droplet size (ASABE S572).
|
||
• Applicators may spray only when wi nd speed is between 3 and 10 mph.
|
||
• DO NOT apply during temperature inversions.
|
||
|
||
Boomless Ground Applications:
|
||
• Applicators are required to select the nozzle and pressure that deliver medium
|
||
or coarser droplet size (ASABE S572) for all applications.
|
||
• DO NOT apply when wind speeds exceed 15 miles per hour at the application
|
||
site.
|
||
• DO NOT apply during temperature inversions.
|
||
|
||
7.4 SPRAY DRIFT ADVISORIES
|
||
|
||
THE APPLICATOR IS RESPONSIBLE FOR AVOIDING OFF-SITE SPRAY DRIFT. BE
|
||
AWARE OF NEARBY NON-TARGET SITES AND ENVIRONMENTAL CONDITIONS.
|
||
|
||
7.4.1 Importance of Droplet Size
|
||
• An effective way to reduce spray dr ift 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.
|
||
7.4.2 Controlling Droplet Size - Ground Boom
|
||
• Volume – Increasing the spray volume so that larger droplets are produced will reduce
|
||
spray drift. Use the highest practical spray volume 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.
|
||
|
||
Page 23
|
||
|
||
|
||
7.4.3 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.
|
||
|
||
7.4.4 Release Height – Aircraft
|
||
• Higher release heights increase t he potential for spray drift.
|
||
|
||
7.4.5 Boom Height – Ground Boom
|
||
• For ground equipment, the boom should remain level with the crop and have minimal
|
||
bounce.
|
||
|
||
7.4.6 Boomless Ground Applications
|
||
• Setting nozzles at the lowest effective height will help to reduce the potential for spray
|
||
drift.
|
||
|
||
7.4.7 Shielded Sprayers
|
||
• Shielding the boom or indi vidual nozzles can reduce spray drift. Consider using
|
||
shielded sprayers. Verify that the shields are not interfering with the uniform deposition
|
||
of the spray on the target area.
|
||
|
||
7.4.8 Temperature and Humidity
|
||
• When making applications in low relative humidity, set up equipment to produce larger
|
||
droplets to compensate for evaporation.
|
||
|
||
Page 24
|
||
|
||
|
||
7.4.9 Temperature Inversions
|
||
• Drift potential is high during a temperature inversion.
|
||
• Temperature inversions are characterized by increasing temperatures with altitude and
|
||
are common on nights with limited cloud cover and light to no wind.
|
||
• They begin to form as the sun sets and often continue into the morning.
|
||
• The presence of an inversion can be indica ted 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 duri ng temperature inversions.
|
||
|
||
7.4.10 Wind
|
||
• Drift potential generally in creases 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.
|
||
|
||
7.4.11 Windblown Soil Particles
|
||
• A24561 Herbicide 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 movem ent of windblown soil include the intensity and
|
||
direction of prevailing winds, vegetative cover, site slope, rainfall, and drainage patterns.
|
||
• Avoid applying A24561 Herbicide if prevailing local conditions may be expected to result
|
||
in off-site movement.
|
||
|
||
7.4.12 Sensitive Areas
|
||
• This pesticide may only be applied when the potent ial for drift to adjacent sensitive areas
|
||
(e.g., residential areas, bodies of water, non-target plants) is minimal (i.e., when the wind
|
||
is blowing away from the sensitive area).
|
||
• To assure that spray will not adversely affe ct adjacent sensitive nontarget plants, apply
|
||
A24561 Herbicide by aircraft at a minimum upwind distance of 400 ft from sensitive
|
||
plants.

|
||
|
||
For soils with pH >7.2 use
|
||
the lowest rate for that
|
||
specific soil texture and
|
||
organic matter.
|
||
Apply in the fall after harvest when the sustained soil
|
||
temperature at a 4-inch depth is less than 55° F and
|
||
falling. Applications to ridge till production systems must
|
||
be made after the formation of ridges or bedded.
|
||
|
||
Apply after September 30 in ND, SD, MN, and WI.
|
||
|
||
Apply after October 15 North of Route 91 in NE and
|
||
south of Route 30 in IA.
|
||
|
||
Apply after October 31 North of Route 136 in IL.
|
||
|
||
A24561 Herbicide should be applied to the harvested
|
||
crop stubble or soil surface without incorporation.
|
||
|
||
Moisture in the form of rain or snow will move and
|
||
activate the product.
|
||
|
||
DO NOT mechanically incorporate in the fall or spring
|
||
after application because this activity may destroy the
|
||
herbicide barrier and weed escapes can occur.
|
||
Preplant
|
||
Incorporated
|
||
Apply as a Preplant Incorporated treatment in the spring
|
||
prior to planting in reduced and conventional tillage dry
|
||
peas.
|
||
|
||
A24561 Herbicide should be shallowly incorporated in the
|
||
soil no deeper than 2 inches.
|
||
|
||
Incorporating A24561 Herbicide deeper than 2 inches
|
||
can result in inconsistent weed control.
|
||
|
||
Minimize furrow and ridge formation in the tillage
|
||
operations.
|
||
Early Preplant
|
||
and
|
||
Preemergence
|
||
(Spring
|
||
Applications)
|
||
Apply early preplant or preemergence up to 3 days after
|
||
planting if seedlings have not broken the soil surface and
|
||
if the seed furrow is completely closed and completely
|
||
covered with soil.
|
||
|
||
Adequate moisture (1/2" to 1") is required for herbicide
|
||
activation from rainfall. If adequate moisture is not
|
||
received within 7 to 10 days after the A24561 Herbicide
|
||
treatment, a shallow incorporation (less than 2 inches)
|
||
may be needed to obtain desired weed control.
|
||
|
||
When activating moisture is not received a planned post-
|
||
emergence application of a labeled herbicide will be
|
||
needed for optimum weed control.
|
||
|
||
Page 29
|
||
|
||
|
||
If an activating rainfall (½” to 1.0”) is not received A24561
|
||
Herbicide will provide a reduced and inconsistent level of
|
||
control of susceptible germinating weeds.
|
||
|
||
If dry conditions persist, weed control may be reduced. If
|
||
weeds are emerged at the time of A24561 Herbicide
|
||
application, use a burndown herbicide at the full-labeled
|
||
rate in combination with A24561 Herbicide as needed.
|
||
|
||
For soils with pH>7.2 use the lowest rate for that specific
|
||
soil texture and organic matter.
|
||
For Weed Control:
|
||
• Refer to Section 8.0 for list of weeds controlled or partially controlled.
|
||
Resistance Management:
|
||
• Refer to Section 3.1.
|
||
Precautions:
|
||
• All cultivars have not been tested for tolerance. Expe riment on a limited basis until on-farm confidence in
|
||
these use patterns and rates are obtained.
|
||
• Adverse crop response may occur on coarse textured soils with low organic matter (less than 1.5%) and
|
||
pH of 7.2 or higher, or on highly eroded soils, hilltops, or in areas of calcareous outcroppings. A24561
|
||
Herbicide use rates should be reduced to 13 fl oz in those areas or not applied in these areas at all.
|
||
Inadequate seed furrow closure or shallow planting (less than 1.5 inch) may result in undesirable crop
|
||
response and this product should not be applied. Po or growing conditions such as excessive moisture,
|
||
low temperatures, soil compaction and diseases may also cause undesirable crop response.
|
||
• A24561 Herbicide will not control emerged weeds. Control emerged weeds with an appropriate
|
||
registered postemergence herbicide(s) or by mechanical means.
|
||
• The risk of crop injury is greater on lighter textur ed soils and with higher use rates, especially when
|
||
coupled with heavy rains or when excessive multiple irrigations occur within 5 days of application.
|
||

|
||
|
||
A24561 Herbicide may be followed by labeled
|
||
postemergence soybean herbicides for increased
|
||
control of grass and broadleaf weeds.
|
||
|
||
When using A24561 Herbicide in no-till or minimum till
|
||
cropping systems, tank mix with an appropriate
|
||
burndown herbicide for improved control of existing
|
||
weeds.
|
||
|
||
For soils with pH>7.2 use the lowest rate for that
|
||
specific soil texture and organic matter.
|
||
|
||
Preplant Incorporation Application:
|
||
|
||
Page 31
|
||
|
||
Incorporation must be uniform and no deeper than 2
|
||
inches. Improper soil incorporation may result in
|
||
erratic weed control and/or crop injury.
|
||
For Weed Control:
|
||
• Refer to Section 8.0 for list of weeds controlled or partially controlled.
|
||
Resistance Management:
|
||
• Refer to Section 3.1.
|
||
Precautions:
|
||
• A24561 Herbicide applied near or after crop emergence may cause severe injury to the crop.
|
||
• For preplant surface application, to the extent po ssible, avoid moving treated soil out of the row or
|
||
moving untreated soil to the surface during planting or weed control will be diminished.
|
||
• A24561 Herbicide will not control emerged weeds. Control emerged weeds with an appropriate
|
||
registered foliar herbicide or by mechanical means.
|
||
• Ensure the seed furrow is closed and the seed covered on acres treated with A24561 Herbicide.
|
||
• Soybean stunting may occur if excessive rainfall oc curs after application but before soybeans emerge.
|
||
Injury is more prevalent under poor drainage or compacted conditions or when soil is saturated for
|
||
long periods of time. Soybeans outgrow stunting once favorable growing conditions return.
|
||
• Seedling disease, nematodes, cold weather, deep pl anting (more than 2 inches), excessive moisture,
|
||
high salt concentration, or drought may weaken soybean seedlings and increase the possibility of crop
|
||
injury.
|
||
