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 +

chroma/ + bm25/ still gitignored (regenerable binary indexes).

.dockerignore: drops venv, eval results, PLAN/README/CLAUDE.md,

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 cleaning equipment or disposing of equipment washwaters or rinsate. DO NOT apply where/when conditions favor runoff.

Groundwater Label 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 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 chlorimuron-methyl and thifensulfuron- methyl 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.

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.

Windblown Soil Particles Synchrony XP 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 [insert product name] if prevailing local conditions may be expected to result in off-site movement.

Directions for Use

It is a violation of Federal law to use this product in a manner inconsistent with its labeling.

DO NOT apply this product in a way that will contact workers or other persons, either directly or through drift. Only protected handlers may be in the area during application. For any requirements specific to your State or Tribe, consult the agency responsible for pesticide regulation.

Product Information

x Synchrony XP herbicide is a dispersible granule formulation which readily dissolves in water. x Synchrony XP may be used in conventional, no-till, or conservation tillage soybean production. x Synchrony XP may be used at various rates and by various use methods depending on geographical location in the use regions Northern, Central and Southern. x Residual applications of Synchrony XP require rainfall or sprinkler irrigation to activate the herbicide. degree of control and duration of effect depend on: rate used, weed spectrum, growing conditions at and following time of treatment, soil pH, texture, organic matter, moisture and precipitation. x Best residual control is obtained if Synchrony XP is applied to moist soil and followed by rainfall or irrigation (~1”) before weeds germinate. Several small rainfalls of less than 1/4” each are not as beneficial as one large rainfall of 1/2-1”.

On dry soil, more moisture is required for activation (1-2”) before weed emergence. If moisture is insufficient to activate the herbicide, a rotary hoeing or shallow cultivation should be made after emergence of the crop while weeds are small enough to be controlled by mechanical means. Deep cultivation reduces the effectiveness of Synchrony XP and should be avoided. Biological Activity

Synchrony XP rapidly inhibits the growth of susceptible weeds. Following application of preplant or preemergence treatment, susceptible weeds may germinate and emerge, but growth then ceases, and leaves become yellow and/or brown by 3-5 days after emergence. Death of leaf tissue and growing point

G7J / Synchrony XP / MSTR / Amendment / 04-28-22 Page 13

will follow in some species while others will remain green but stunted and noncompetitive.

Synchrony XP will provide best results when applied postemergence to young, actively growing weeds. Leaves of susceptible plants yellow 3-5 days after application, followed, in controlled plants, by the death of the growing point.

Synchrony XP will provide complete control of susceptible weeds in 7-21 days. Suppressed plants may remain green but will be stunted and noncompetitive. Degree of control depends on: weed spectrum; weed size (if weeds are large, use higher spray volume); growing conditions at and following treatment; soil moisture; precipitation; and spray adjuvants.

Treating weeds under stress or large weeds may result in only partial control. Stress may be caused by: x abnormal weather (hot or cold) x mechanical injury from cultivation x drought x water-saturated soil x disease x insect injury x prior herbicide injury

Important Use Restrictions

x DO NOT graze treated fields or harvest for hay within 14 days after application. x Synchrony XP can be applied in tank mixtures with organophosate insecticides or at any time preceding or following an application of an organophosphate insecticide on any STS®, STS®/RR soybean variety or soybeans with BOLT™ technology. Tank mixtures of Synchrony XP plus organophosphate insecticides applied to STS®, STS®/RR soybean varieties or soybeans with BOLT™ technology may result in minor transient crop response (i.e. stunting and/or chlorosis). x DO NOT apply Synchrony XP within 14 days before or after an application of an organophosphate insecticide on any soybean variety that is not STS®, STS®/RR or soybeans with BOLT™ technology, as severe crop injury may occur. x DO NOT apply more than a total of 0.82 ounces active ingredient chlorimuron ethyl per acre per year in the Northern and Central Region states or 1.07 ounces active ingredient chlorimuron ethyl per acre per year in the Southern Region states. This includes combinations of preemergence and postemergence applications of chlorimuron ethyl products. x DO NOT apply more than a total of 0.75 ounces active ingredient of thifensulfuron methyl per acre per year in all use regions specified on this label. x DO NOT apply this product in a way that will contact workers or other persons, either directly or through drift. x Only protected handlers may be in the area during application. x DO NOT apply this product through any type of irrigation system. x DO NOT use liquid nitrogen fertilizer as the total carrier solution. x DO NOT apply to frozen or snow covered ground. x DO NOT cultivate within 7 days of application. x DO NOT tankmix “Poast Plus” with 0.375 oz/acre Synchrony XP unless the soybean is designated as an STS ® variety or soybeans with BOLT™ technology. x DO NOT apply during a temperature inversion, when winds are gusty, or when other conditions could produce poor coverage and/or off-target spray movement. x DO NOT apply Synchrony XP herbicide by air in the state of New York. x DO NOT apply Synchrony XP if rain is expected within 1 hour or weed control may decrease. x Many crops are sensitive to Synchrony XP.

G7J / Synchrony XP / MSTR / Amendment / 04-28-22 Page 14

Injury to or loss of desirable trees or vegetation may result from failure to observe the following: x DO NOT apply Synchrony XP or drain or flush equipment on or near desirable trees or other plants, on areas where their roots may extend, or in locations where the chemical may be washed or moved into contact with their roots. x DO NOT use on lawns, walks, driveways, tennis courts or similar areas.

Important Use Precautions

x Calibrate sprayers only with clean water away from the well site. x Make scheduled checks of spray equipment. x Ensure that all operation employees accurately measure pesticides. x Mix only enough product for the job at hand and avoid overfilling of spray tank. x When triple-rinsing the pesticide container, be sure to add the rinsate to the spray mix. x Failure to remove even small amounts of Synchrony XP from application equipment may result in injury to subsequently sprayed crops. x Keep from contact with fertilizers, insecticides, fungicides and seeds during storage. x Avoid storage of pesticides near well sites. x Stress effects some weeds, such as pigweed, more than others. Delay application until stress passes and weeds start to grow again. x Severe stress (drought, disease, insect damage, or nutrient deficiency such as iron chlorosis) following application may also result in poor weed control. x Applications made when the crop is under stress from moisture, cold, heat, high humidity, disease, insect pressure and prior herbicide stress may result in excessive crop response.

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.

G7J / Synchrony XP / MSTR / Amendment / 04-28-22 Page 15

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. 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 most effective way to reduce drift potential 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 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.

BOOMLESS GROUND APPLICATIONS Setting nozzles at the lowest effective height will help to reduce the potential for 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.

HANDHELD TECHNOLOGY APPLICATIONS Take precautions to minimize spray drift.

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

G7J / Synchrony XP / MSTR / Amendment / 04-28-22 Page 16

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 increases with wind speed. AVOID APPLICATIONS DURING GUSTY WIND CONDITIONS. Applicators need to be familiar with local wind patterns and terrain that could affect spray drift.

Sensitive Areas

Making applications when there is a sustained wind moving away from adjacent sensitive areas (e.g., residential areas, bodies of water, known habitat for threatened or endangered species, non-target crops) is an effective way to minimize the effect of spray drift.

Drift Control Additives

Using product compatible drift control additives can reduce drift potential. When a drift control additive is used, read and carefully observe cautionary statements and all other information on the additive’s label. If using an additive that increases viscosity, ensure that the nozzles and other application equipment will function properly with a viscous spray solution. preferred drift control additives have been certified by the Chemical Producers and Distributors Association (CPDA).

Shielded Sprayers

Shielding the boom or individual nozzles can reduce the effects of wind. However, it is the responsibility of the applicator to verify that the shields are preventing drift and not interfering with uniform deposition of the product.

Air Assisted (air blast) Field Crop Sprayers

Air assisted field crop sprayers carry droplets to the target via a downward directed air stream. Some may reduce the potential for drift, but if a sprayer is unsuitable for the application and/or set up improperly, high drift potential can result. It is the responsibility of the applicator to determine that a sprayer is suitable for the intended application, is configured properly, and that drift is not occurring.

Air Assisted (air blast) Tree and Vine Sprayers

Air assisted tree and vine sprayers carry droplets into the canopy of trees and vines via a radially or laterally directed air stream. These sprayers are not suitable for applying herbicides.

Herbicide Resistance Management

Synchrony XP, which contains the active ingredients chlorimuron ethyl and thifensulfuron methyl, are both group 2 herbicides based on the mode of action classification system of the Weed Science Society of America.

When herbicides with mode of action classifications that effect the same biological sites of action are used repeatedly over several years to control the same weed species in the same treatment area, naturally-occurring resistant biotypes may survive a correctly applied herbicide treatment, propagate, and become dominant in that area. Adequate control of these resistant weed biotypes cannot be expected. If weed control is unsatisfactory, it may be necessary to retreat the problem area using a product effecting a different biological site of action.

To better manage herbicide resistance through delaying the proliferation and possible dominance of herbicide resistant weed biotypes, it may be necessary to change cultural practices within and between

G7J / Synchrony XP / MSTR / Amendment / 04-28-22 Page 17

crop seasons such as using a combination of tillage, retreatment, tank-mix partners and/or sequential herbicide applications that have a different site of action. Weed escapes that are allowed to go to seed will promote the spread of resistant biotypes. 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 If using post-emergence herbicides or tank mixes, control weeds early when they are relatively small. x Apply full rates of Canopy Blend for the most difficult to control weed in the field at the specified time to minimize weed escapes. x Scout fields after application to detect weed es capes 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 local company representative, local retailer, or county extension agent. x Contact your local 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 mode of action. Products with multiple active may be controlled by only one of the active ingredients in this product. x If resistance is suspected, treat weed escapes with an herbicide having a mode of action other than Group 2 and 5 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: Failure to control a weed species normally controlled by the herbicide at the dose applied, especially if control is achieved on adjacent weeds; A spreading patch of non-controlled plants of a particular weed species; and Surviving plants mixed with controlled individuals of the same species.

Additionally, users should follow as many of the following herbicide resistance management practices as is practical: x Use a broad-spectrum herbicide with other mode of action as a foundation in a weed control program, if appropriate. x Utilize sequential applications of herbicides with alternative modes of action. x Rotate the use of this product with non-Group 2 and/or 5 herbicides. x Avoid making more than two sequential applications of Canopy Blend and any other Group 2 and/or 5 herbicides within a single growing season unless mixed with an herbicide with a different mode 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 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.

Tank mixtures of Synchrony XP plus organophosphate insecticides applied to STS ®, STS®/RR soybean varieties or soybeans with BOLT™ technology may result in minor transient crop response (i.e. stunting and/or chlorosis). DO NOT apply Synchrony XP within 14 days before or after an application of an organophosphate insecticide on any soybean variety that is not STS®, STS®/RR or soybeans with BOLT™ technology, as severe crop injury may occur.

Other than the exceptions noted, and in addition to the tank mix partners and rates indicated in this label, Synchrony XP may be tank mixed or followed with sequential applications of other products registered for use in soybeans. Synchrony XP may be applied in tank mix combinations with full or reduced rates of other products provided:

The tank mix product is labeled for the same timing, method of application, adjuvants, and use restrictions as Synchrony XP . The tank mix is not specifically prohibited on the label of the tank mix product.

The tank mix combination is compatible as determined by a “jar test” described in the TANK MIX COMPATIBILITY TESTING section below.

G7J / Synchrony XP / MSTR / Amendment / 04-28-22 Page 20

Weed control and crop safety resulting from the use of tank mixtures not specifically noted on this label, or in separately published company directions, are the responsibility of the user.

Tank Mix Compatibility Testing

Perform a jar test prior to tank mixing to ensure compatibility of Synchrony XP 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.

Mixing Instructions

Fill the tank 1/4 to 1/3 full of water.
While agitating, add the required amount of Synchrony XP.
Continue adequate agitation.
Synchrony XP needs to be thoroughly mixed with water in the spray tank before adding any other material. As the tank is filling, add (in order): other herbicide(s), the required spray adjuvant, and the nitrogen fertilizer where required.
Apply Synchrony XP spray preparation within 24 hours of mixing to avoid product degradation.
If the mixture has settled, thoroughly reagitate before using.

Cultivation

DO NOT cultivate within 7 days of application. Cultivation may put weeds under stress by pruning roots, thus diminishing control.

Cultivation approximately 14 days after application will help control suppressed weeds.

Apply Synchrony XP at 1.125 oz/acre to preserve the STS® trait in STS® soybean seed production. Synchrony XP used at 1.125 oz/ac will give residual control of newly germinating broadleaf weeds (see Preemergence or Preplant Spring Application, Preemergence Residual Control).

Sequential Applications:

A follow up application of CLASSIC ® herbicide or Synchrony XP herbicide may be made 2-3 weeks after a Synchrony XP application to control weeds with multiple germination flushes or weeds under stress such as burcucumber, cowpea, giant ragweed, morningglory, and sicklepod. See Rotational Crop Guidelines for intervals following sequential applications.

Spray Additives

For directions for use on addition of crop oil concentrate, nonionic surfactant and ammonium nitrogen fertilizer, see the 'Spray Additives' section under 'Application Information - All Uses’.

Tank Mixes

Synchrony XP and glyphosate herbicides such as ABUNDIT ® brand herbicides on STS®/RR stacked-trait soybeans or soybeans with BOLT™ technology:

Synchrony XP may be tank mixed with glyphosate-containing herbicides for improved control of broadleaf weeds not completely controlled by either product alone.

Synchrony XP and “Flexstar” brands, “Reflex”, “Ultra Blazer”, or “Cobra” Herbicides On Any STS ® soybean or soybeans with BOLT™ technology:

For control of up to 2” eastern black nightshade and for improved common ragweed control, Synchrony XP may be tankmixed with "Flexstar" brands, "Reflex”, "Ultra Clazer" or "Cobra" herbicides.

For control of prickly sida and hemp sesbania, tank mix Synchrony XP with “Cobra”. Use the higher “Cobra” rate when prickly sida or hemp sesbania are heavy or if prickly sida and hemp sesbania approach the maximum size of 1” or 4”, respectively. DO NOT use crop oil concentrate when tankmixing Synchrony XP and “Cobra” at the higher rates.

Tank mix applications of Synchrony XP plus “Flexstar”, “Reflex”, “Ultra Blazer”, or “Cobra” may not control weeds listed on the Synchrony XP label as completely as applications of Synchrony XP alone.

Refer to the “Flexstar”, “Reflex”, “Ultra Blazer” and “Cobra” labels for the appropriate rate based on the weed sizes to be controlled.

Synchrony XP and “FirstRate” herbicide:

For improved ragweed (non ALS resistant) and cocklebur control, add between 0.075 - 0.3 oz/acre “Firstrate” to SYNCHRONY® XP. These tankmixes will control up to 10” cocklebur or common ragweed and up to 12” giant ragweed. Use a lower amount of “Firstrate” when weeds are less than the maximum size and under good growing conditions. Use a higher amount of “Firstrate” when weeds are approaching the maximum size and/or under unfavorable growing conditions.

G7J / Synchrony XP / MSTR / Amendment / 04-28-22 Page 28

Synchrony XP and Postemergence Grass Herbicides:

Synchrony XP and Synchrony XP tankmixes may be tank mixed with postemergence grass herbicides such as ASSURE ® II herbicide. For best results, apply Synchrony XP seven days before or one day after the grass herbicide. Refer to the grass herbicide label for precautions and specific use information.

Application Equipment

Ground Application (see also Mandatory Spray Drift Management)

Broadcast Application

x Postemergence in soybeans, use a minimum of 10 gal water per acre. Under heavy weed pressure or dense crop foliage, increase minimum spray volume to 15-25 gal per acre. For best performance, select nozzle and pressure combinations that deliver medium to coarse spray droplets, as indicated, for example, by ASABE standard S572. x Preemergence in soybeans, use a minimum of 10 gal water per acre. For best performance, select nozzle and pressure combinations that deliver coarse to very coarse spray droplets, as indicated, for example, by ASABE standard S572. x For burndown applications of existing vegetation, use a minimum of 15 gal water per acre. For large weeds and/or heavy residue, increase gallonage to ensure coverage. For best performance, select nozzle and pressure combinations that deliver medium to coarse spray droplets, as indicated, for example, by ASABE standard S572.

Aerial Application (See Also Mandatory Spray Drift Management)

x Use nozzle types and arrangements that will provide optimum spray distribution and maximum coverage at 2-5 gal per acre. x Use a minimum of 2 gal water per acre. under heavy weed pressure or dense crop foliage, increase the minimum spray volume to 5 gal per acre. x DO NOT apply during a temperature inversion, when wind speed is less than 2 mph or above 10 mph, or when other conditions could produce poor coverage and/or off-target spray movement. x DO NOT apply Synchrony XP herbicide by air in the state of New York

Rotational Crop Guidelines – All Uses

Crop rotation intervals noted in the table below are based on crops grown under favorable growing conditions. Crops grown under unfavorable environmental conditions, such as drought, nutrient deficiency, high salts, disease and insect pressure may demonstrate reduced tolerance to crop protection chemicals. When deciding on a particular crop to replant in your fields, carefully consider your particular soil and other field conditions (see IMPORTANCE OF SOIL PH section of this label).

x Important: Crops other than soybeans following a Synchrony XP application can vary in their sensitivity to low concentrations of Synchrony XP remaining in the soil. Rotational crop guidelines must be followed.

Northern Region: The states of Minnesota, South Dakota, Wisconsin (fields north of interstate 90 between Lacrosse and Madison and fields north of interstate 94 between Madison and Milwaukee), Iowa (fields inside the boundaries of the Clarion-Nicollet-Webster and Hamburg-Ida-Monona soil associations and fields located inside the historic floodplain of the Missouri river), Nebraska (fields north of route 30 and west of route 281), and New York (fields north of interstate 90).

The Importance of Soil pH

Soil pH varies greatly, even within the same field, pH variations as much as 2 pH units are common.

G7J / Synchrony XP / MSTR / Amendment / 04-28-22 Page 31

Composite soil samples taken across an entire field, such as those samples taken for soil fertility recommendations, may not detect areas of high pH. Sub-sampling is recommended for areas likely to have pH values higher than the field average. The following is a non-inclusive list of potential high pH areas where subsampling is recommended.

Where different soil types are evident within a field, sample soil types separately.

Where conditions vary within a field, sample areas separately, such as: x areas bordered by limestone gravel roads, x river bottoms subject to flooding, x low areas in hardpan soils where evaporative ponds may occur, x eroded hillsides, x along drain tile lines, and x areas where drainage ditch spoil has been spread.

Where lime has not been deeply incorporated, soil may exhibit significantly higher pH values in the upper 3 inches of soil. Composite soil samples taken at a 6-8 inch depth may not reflect the elevated pH near the surface. in these cases, shallow sampling the upper 3 inches is advised.

Determine soil pH by laboratory analysis using a 1:1 soil: water suspension.

Sprayer Preparation and Cleanup

It is important that spray equipment is clean and free of previous pesticide deposits before using Synchrony XP and then properly cleaned out following application. Clean all application equipment before applying Synchrony XP. 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 Synchrony XP, thoroughly clean all mixing and spray equipment to avoid subsequent crop injury.

Note: x When cleaning spray equipment before applying Synchrony XP, read and follow label directions for proper rinsate disposal of the product previously sprayed. x Steam cleaning of aerial spray tanks will help to dislodge any visible pesticide deposits. x When spraying or mixing equipment will be used over an extended period to apply multiple loads of Synchrony XP, partially fill the tank with fresh water at the end of each day of spraying, flush the boom and hoses, and allow to sit overnight. Cleanup Procedure

Drain the tank and thoroughly hose down the interior surfaces. Flush the tank, hoses, and boom with clean water for a minimum of 5 min.
Partially fill the tank with clean water and add one gallon of household ammonia* (containing 3% active) for every 100 gallons of water. Finish filling the tank with water, then flush the cleaning solution through the hoses, boom, and nozzles. Add more water to completely fill the tank and allow to agitate/recirculate for at least 15 min. Again, flush the hoses, boom, and nozzles with the cleaning solution, then drain the tank.
Repeat Step 2.
Remove the nozzles, screens, and end caps of sprayer booms and clean separately in a bucket containing the cleaning agent and water.
Thoroughly rinse the tank with clean water for a minimum of 5 min, flushing the water through the hoses and boom.

Equivalent amounts of an alternate strength ammonia solution or a tank cleaner recommended in the company bulletin “Sulfonylurea herbicides, A guide to equipment cleanout,” may be used.
