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 +

+PRODUCT INFORMATION
+Evik DF controls most annual broadleaf and grass weeds (see list under each crop). 
+When applied before weed emergence, Evik DF kills weeds as they germinate by 
+entering roots. On existing weeds, it is effective through leaf contact.
+
+Evik DF
+Page 8
+x Fields with difficult to control weeds should be planted in rotation with crops that allow 
+the use of herbicides with an alternative mode of action or different management 
+practices.
+x 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
+x Do not use more than two applications of this or any other herbicide with 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 the difficult to control 
+weeds.
+Scout and inspect fields following application
+x Prevent an influx of weeds into the field by controlling weeds in field borders.
+x Scout fields after application to verify that the treatment was effective.
+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.
+x Report non-performance of this product 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
+x 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 post-harvest to prevent seed production.
+Resistant Weeds
+x Contact your local Syngenta representative, 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.

+APPLICATION PROCEDURES
+Equipment – All aerial and ground application equipment must be properly maintained 
+and calibrated using appropriate carriers or surrogates.
+Other State and Local Requirements – Applicators must follow all state and local 
+pesticide drift requirements regarding application of ametryn. Where states have more 
+stringent regulations, they must be observed.
+Ground application: Use conventional ground sprayers equipped with nozzles that 
+provide accurate and uniform application. Be certain that nozzles are uniformly spaced 
+and the same size. Calibrate sprayer before use and recalibrate at the start of each 
+season and when changing carriers.
+Use a pump with capacity to: (1) maintain specified psi at nozzles as recommended by 
+the nozzle manufacturer, (2) provide sufficient agitation in tank to keep mixture in 
+suspension, and (3) to provide a minimum of 20% bypass at all times. Use centrifugal 
+pumps which provide propeller shear action for dispersing and mixing this product. The 
+pump should provide a minimum of 10 gal/minute/100 gal tank size circulated through a 
+correctly positioned sparger tube or jets.
+Use screens to protect the pump and to prevent nozzles from clogging. Screens placed 
+on the suction side of the pump should be 16-mesh or coarser. Do not place a screen 
+in the recirculation line. Use 50-mesh or coarser screens between the pump and boom, 
+and where required, at the nozzles. Check nozzle manufacturer’s recommendations.
+For band applications, calculate amount to be applied per acre as follows:
+band width in inches X broadcast rate = amount needed
+row width in inches per acre per acre of field
+Aerial application: Use aerial application only where specified in the use directions. 
+Avoid applications under conditions where uniform coverage cannot be obtained or 
+where excessive spray drift may occur.
+Avoid application to humans or animals. Flagmen and loaders need to avoid inhalation 
+of spray mist and prolonged contact with skin.
+Note: Aerial application is prohibited except for use on sugarcane in Florida.
+Mandatory Spray Drift Management
+Aerial Applications:
+x 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.
+x Applicators are required to use a Medium or coarser droplet size (ASABE S572.1).
+
+Evik DF
+Page 10
+x Applicators must use ½ swath displacement upwind at the downwind edge of the 
+field.
+x Do not apply when wind speeds exceed 10 mph at the application site.
+x 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.
+x Do not apply during temperature inversions.
+Ground Boom Applications:
+x User must only apply with the release height recommended by the manufacturer, but 
+no more than 4 feet above the ground or crop canopy.
+x 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 manufacturer’s recommendations for setting up 
+nozzles. Generally, to reduce fine droplets, nozzles should be oriented parallel with 
+the airflow in flight.
+BOOM HEIGHT – Ground Boom 
+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.
+
+Evik DF
+Page 11
+SHIELDED SPRAYERS
+Shielding the boom or individual nozzles can reduce spray drift. Consider using shielded 
+sprayers. Verify that the shields are not interfering with the uniform deposition of the 
+spray on the target area.
+TEMPERATURE AND HUMIDITY
+When making applications in hot and dry conditions, use larger droplets to reduce 
+effects of evaporation.
+TEMPERATURE INVERSIONS
+Drift potential is high during a temperature inversion. Temperature inversions are 
+characterized by increasing temperature with altitude and are common on nights with 
+limited cloud cover and light to no wind. The presence of an inversion can be indicated 
+by ground fog or by the movement of smoke from a ground source or an aircraft smoke 
+generator. Smoke that layers and moves laterally in a concentrated cloud (under low 
+wind conditions) indicates an inversion, while smoke that moves upward and rapidly 
+dissipates indicates good vertical air mixing. Avoid applications during temperature 
+inversions.
+WIND
+Drift potential generally increases with wind speed. AVOID APPLICATIONS DURING 
+GUSTY WIND CONDITIONS.
+Applicators need to be familiar with local wind patterns and terrain that could affect 
+spray drift.
+Handheld Technology Applications:
+x Take precautions to minimize spray drift.
+MIXING PROCEDURES
+All Uses: (1) Be sure sprayer is clean and not contaminated with any other materials, 
+or crop injury or sprayer clogging may result. (2) Fill tank ¼ full with clean water or 
+nitrogen solution (may be used in corn). (3) Start agitation. (4) Be certain that the 
+agitation system is working properly and creates a rippling or rolling action on the liquid 
+surface. (5) Make a slurry by adding Evik DF to a small amount of water in a separate 
+container and pour slurry into tank. (6) Continue filling tank until 90% full. Increase 
+agitation if necessary to maintain surface action. (7) Add tank mix herbicide(s) after this 
+product is thoroughly suspended. (8) Finish filling tank. Maintain agitation to avoid 
+separation of materials. (9) Empty tank as completely as possible before refilling to 
+prevent buildup of emulsifiable concentrate residue from possible tank mix herbicides. 
+(10) If an emulsifiable concentrate film starts to build up in tank, drain it and clean with 
+strong detergent solution or solvent. (11) Clean sprayer thoroughly immediately after 
+use by flushing system with water containing a detergent.
+Compatibility Test: Nitrogen solutions may replace all or part of the water in the spray 
+in corn. Since nitrogen solutions can vary, even within the same analysis, check
+
+Evik DF
+Page 12
+compatibility each time before use. Commercial application equipment may improve 
+compatibility in some instances. The following test assumes a spray volume of 25 
+gal/A. For other spray volumes, make appropriate changes in the ingredients. Check
+compatibility using this procedure.
+1. Add 1 pt of fertilizer to each of 2 one-qt jars with tight lids.
+2. To one of the jars, add ¼ tsp or 1.2 milliliters of a compatibility agent approved 
+for this use (¼ tsp is equivalent to 2 pt/100 gal spray). Shake or stir gently to 
+mix. Examples of compatibility agents include Compex® and Unite®.
+3. To both jars, add 1.4 teaspoons of Evik DF for each pound per acre to be 
+applied.
+4. After adding all ingredients, put lids on and tighten, and invert each jar 10 times 
+to mix. Let the mixtures stand 15 minutes and then look for separation, large 
+flakes, precipitates, gels, heavy oily film on the jar, or other signs of 
+incompatibility. Determine if the compatibility agent is needed in the spray 
+mixture by comparing jars. If either mixture separates, but can be remixed 
+readily, the mixture can be sprayed as long as good agitation is used. If the 
+mixtures are incompatible, try slurrying the Evik DF in water before addition. If 
+still incompatible, do not use the nitrogen solution and Evik DF in the same spray 
+tank.
+CROP USE DIRECTIONS
+Corn (Field Corn, Popcorn)
+Evik DF controls annual broadleaf and grass weeds including Texas panicum (Texas 
+millet), fall panicum, signalgrass (Brachiaria spp.), goosegrass, crabgrass, 
+barnyardgrass, giant foxtail, yellow and green foxtails, cocklebur, lambsquarters, Florida 
+pusley, morningglory, pigweed, wild mustard, ragweed, velvetleaf, and smartweed. 
+Weeds taller than specified in the rate table will not be controlled.
+Apply Evik DF as a postemergence directed spray to weeds after the smallest corn is at 
+least 12 inches tall (measured to the highest leaf surface on free-standing plants).
+Restriction: Do not spray over top of corn, or injury will occur. Do not apply within 3 
+weeks of tasseling.
+Apply in a minimum of 20 gal of water per acre to assure uniform coverage 
+(nonpressure nitrogen solution may be substituted for all or part of the water). The 
+entire weed must receive spray to be killed. Add a surfactant such as X-77®, DuPont 
+WK, or Tronic at the rate of 2 qt/100 gal of spray mixture (0.5% of spray volume).
+
+Evik DF
+Page 13
+It is recommended that gauge wheels and/or leaf lifter equipment be used to prevent 
+leaf contact with the spray. Drop nozzles may be used, but extreme care must be taken 
+to keep the spray or drift from contacting the leaves and especially the whorl of the corn 
+plant. Be sure the entire spray pattern is directed downward. Apply at a spray pressure 
+of 30 psi or less to prevent “bounce back”—spray bouncing off soil or weeds and 
+settling on corn leaves.
+Restriction: Do not make more than one application per year. Do not apply more than 
+2.0 lb Evik DF (1.58 lb ai) per acre per year.

+The following rotational crops may be planted after the last Evik DF application in 
+sugarcane.
+State Crops to be Planted
+Minimum Rotation 
+Interval (Months)
+FL Rice, Sweet Corn 4
+Celery, Cole Crops, Leafy Vegetables, 
+Radishes, Snap Beans
+9
+FL, HI, LA, TX Soybeans, Sorghum, Cotton 11
+Aerial Application (Florida Only): Use aerial application only in Florida where 
+broadcast applications are specified. Apply a minimum of 5 gal total volume per acre. 
+Avoid applications under conditions where uniform coverage cannot be obtained or 
+where excessive spray drift may occur. In order to assure that spray will be controllable 
+within the target area when used according to label directions, make applications at a 
+maximum height of 10 ft, using low-drift nozzles at a maximum pressure of 40 psi, and 
+restrict application to periods when wind speed does not exceed 10 mph. To assure 
+that spray will not adversely affect adjacent sensitive non-target plants, apply Evik DF 
+alone by aircraft at a minimum upwind distance of 800 ft from sensitive plants.
+Florida: Apply 0.5-1.5 lb of Evik DF broadcast or directed to the base of plant or ratoon 
+sugarcane to emerged weeds. Use a minimum of 20 gal of water per acre if applied by 
+ground application. Avoid wetting sugarcane foliage, or injury may occur. Use nozzle 
+tips which will minimize atomization or spray drift. Use the higher rate for high grass 
+populations. After 30 days, one additional application may be made prior to close-in if 
+needed. To control alexandergrass (Brachiaria plantaginea), apply at the 3 to 4-leaf 
+stage or before 3 inches tall. For mixed weed infestations, use 1.5 lb of Evik DF plus 
+0.5 lb acid equivalent of 2,4-D amine per acre and/or 2 qt of surfactant, such as X-114 
+or ACL 209, for each 100 gal of spray to improve weed control. Observe all precautions 
+and limitations on labeling of all products used in mixtures.
+Restriction (Florida): Do not apply more than 1.5 lb of Evik DF (1.18 lb ai) per acre in 
+a single application. Do not exceed a total of 3.0 lb Evik DF (2.37 lb ai) per acre per 
+crop cycle. Do not make more than two applications of Evik DF per year.
+Hawaii: Use one of the following methods in plant or ratoon sugarcane for control of 
+ageratum, rattlebox (Crotalaria spp.), dallisgrass, fireweed, goosegrass (Eleusine
+indica), guineagrass, Japanese tea, kukaipuaa, and other crabgrass species (Digitaria
+spp.), morningglory, pualele (sowthistle), common purslane, Richardia spp., 
+spanishneedles, wild pea bean, Amaranthus spp., Flora’s paintbrush, foxtail, junglerice, 
+and swollen fingergrass.
+1. Apply up to 3.0 lb of Evik DF per acre before weeds or sugarcane emerge. A 
+second application, not to exceed 3 lb/A, may be made, if needed, approximately 
+30 days before close-in. If needed, a third application not to exceed 3 lb/A may 
+be applied at close-in.
+
+Evik DF
+Page 16
+2. Apply 2.5-3.0 lb of Evik DF plus 2.5-5 lb of Karmex 80W before sugarcane and 
+weeds emerge.
+A second application at 2.5-3.0 lb of Evik DF plus 2.5-5 lb of Karmex 80W may 
+be made, as needed, postemergence to sugarcane and weeds. A third 
+application at 2.5-3 lb of Evik DF plus 2.5-3 lb of Karmex 80W may be applied 
+prior to close-in.
+For best results when Karmex 80W is used on emerged weeds, add a nonionic 
+surfactant to the spray at the rate of 1-2 qt per 100 gal and apply as a directed 
+spray.
+Restrictions (Hawaii): Use the minimum preemergence rates on nonirrigated 
+sugarcane (high rainfall areas), on land first cropped to sugarcane, and for light weed 
+infestations. Do not exceed a total of 9.0 lb of Evik DF (7.10 lb ai) per acre per crop 
+cycle. Do not make more than three applications of Evik DF per year. Do not apply 
+more than 3.0 lb of Evik DF (2.37 lb ai) per acre in a single application.
+Precautions (Hawaii): (1) Sugarcane growing in areas of exposed sub soil, in rocky 
+areas, or in soils of low adsorptive capacity may show temporary chlorosis following 
+treatment. (2) Injury to sugarcane may occur when under moisture stress. (3) Certain 
+sugarcane varieties may show a temporary chlorosis or stunting as a result of over-the-
+top application.
+Louisiana: Use the directions below for control of these weeds:
+Weed Height Weeds Controlled
+Up to 3.0 inches itchgrass (raoulgrass)*
+Up to 4.0 inches barnyardgrass, crabgrass, fall panicum, foxtail, goosegrass,
+Texas panicum
+Up to 5.0 inches annual sowthistle, common chickweed, henbit, paleseed 
+plantain, swinecress
+Up to 6.0 inches Brachiaria spp., browntop panicum, cocklebur, Florida 
+pusley, common lambsquarters, morningglory, pigweed,
+ragweed, smartweed, velvetleaf, wild mustard
+*Controls emerged itchgrass. May not control itchgrass germinating after treatment.
+Broadcast or band by ground equipment over the top of plant or ratoon sugarcane 1.5 lb
+of Evik DF plus 0.5 lb acid equivalent of 2,4-D amine plus 1 qt of crop oil concentrate, 
+such as Agri-Dex, Amoco, or Unico (or 1 pt of nonionic surfactant, such as DuPont WK, 
+X-77, or LOC) in a minimum of 20 gal of water per acre.
+Follow with 1 repeat over-the-top or directed application, if needed, using 1.5 lb of Evik 
+DF plus 0.5 lb of 2,4-D amine plus 1 qt of crop oil concentrate (or 1 pt of nonionic
+
