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

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

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

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

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

Environmental Hazards
Cannonball WG
Page 4
This pesticide is toxic to fish, aquatic invertebrates, oysters and shrimp. For terrestrial
uses: Do not apply directly to water, to areas where surface water is present, or to
intertidal areas below the mean high water mark. Do not contaminate water when
disposing of equipment washwater or rinsates.
Groundwater Advisory
This chemical has properties and characteristics associated with chemicals detected in
groundwater. This chemical may leach into groundwater if used in areas where soils
are permeable, particularly where the water table is shallow.
Surface Water Advisory
This chemical may contaminate water through drift of spray in wind. This chemical has
a high potential for runoff for several months or more after application. Poorly draining
soils and soils with shallow water tables are more prone to produce runoff that contains
this chemical. A level, well-maintained vegetative buffer strip between areas to which
this chemical is applied and surface water features including ponds, streams, and
springs will reduce the potential for contamination of water from rainfall runoff. Runoff of
this chemical will be reduced by avoiding applications when conditions favor runoff (for
example when soils are saturated and/or significant rainfall is forecast in the next 48
hours). Sound erosion control practices will reduce this chemicals contribution to
surface water contamination.
Physical or Chemical Hazards
Do not use or store near heat or open flame. Do not use with or store near any
oxidizing agents.

PRODUCT INFORMATION
Cannonball WG is a protective fungicide used to aid in the control of soil, crown, and
foliar diseases. All applications must be made according to the use directions that
follow.
PRODUCT USE INSTRUCTIONS
Nassau and Suffolk counties of New York: Use limited to strawberries and onions.
Not for use in the state of Hawaii.
Application: Thorough coverage is necessary to provide good disease control. Make
up no more spray solution than is needed for application. Avoid spray overlap, as crop
injury may occur.
Efficacy: Under certain conditions conducive to extended infection periods, use
another registered fungicide for additional applications if maximum amount of
Cannonball WG has been used. If resistant isolates to Group 12 fungicides are present,
efficacy can be reduced. Under high disease pressure, it is advised to use the highest
rate and shortest interval.
Rotational Crops: DO NOT plant any crop which is not registered for use with fludioxonil
for a period of 30 days, unless a shorter interval is specified on the following list.

RESISTANCE MANAGEMENT
For resistance management, Cannonball WG contains a Group 12 fungicide. Any fungal
population may contain individuals naturally resistant to Cannonball WG and other
Group 12 fungicides. A gradual or total loss of pest control may occur over time if these
fungicides are used repeatedly in the same fields. Follow appropriate resistance-
management strategies.
Cannonball WG contains fludioxonil which is in the phenylpyrrole class of chemistry and
has a unique mode of action, which prevents fungal respiration (Fungicide Action Group
12). Fungal isolates with acquired resistance to Group 12 may eventually dominate the
fungal population if Group 12 fungicides are used repeatedly in the same field or in
successive years as the primary method of control for targeted species. This may result
in partial or total loss of control of those species by fludioxonil or other Group 12
fungicides. A disease management program that includes alternation or tank mixes
between Cannonball WG and other labeled fungicides that have a different mode of
action may prevent pathogen populations from developing resistance. Sanitation and
other cultural practices to minimize disease are also advised to aid in control as well as
to assist in preventing/delaying resistance development.
To delay fungicide resistance, take one or more of the following steps:
• Rotate the use of fludioxonil or other Group 12 fungicides within a growing season
sequence with different groups that control the same pathogens.
• Use tank mixtures with fungicide from a different group that are equally effective on
the target pest when such use is permitted. Use at least the minimum application
rate as labeled by the manufacturer.
• Adopt an integrated disease management program for fungicide use that includes
scouting, uses historical information related to pesticide use, and crop rotation, and
which considers host plant resistance, impact of environmental conditions on
disease development, disease thresholds, as well as cultural, biological and other
chemical control practices.
• Where possible, make use of predictive disease models to effectively time fungicide
applications. Note that using predictive models alone is not sufficient to manage
resistance.
• Monitor treated fungal populations for resistance development.
• Contact your local extension specialist or certified crop advisor for any additional
pesticide resistance-management and/or IPM directions for specific crop and
pathogens.
Cannonball WG
Page 10
• For further information or to report suspected resistance contact Syngenta at 1-866-
Syngent(a) (866-796-4368). You can also contact your pesticide distributor or
university extension specialist to report resistance.
Spray Drift Management: To avoid spray drift, do not apply when conditions favor drift
beyond the target area. The interaction of many equipment and weather-related factors
determine the potential for spray drift. AVOIDING SPRAY DRIFT AT THE
APPLICATION SITE IS THE RESPONSIBILITY OF THE APPLICATOR AND THE
GROWER.
Adjuvants: When an adjuvant is to be used with this product, Syngenta recommends
the use of a Chemical Producers and Distributors Association certified adjuvant unless
otherwise restricted for a specific crop.
IPM: Cannonball WG should be integrated into an overall disease and pest
management strategy (IPM) whenever the use of a fungicide is required. Cultural and
sanitation practices known to reduce disease development should be followed. Consult
your local agricultural authorities for additional IPM strategies established for your area.
SPRAY EQUIPMENT
Nozzles
• Equip sprayers with nozzles that provide accurate and uniform application.
• As appropriate, nozzles must be the same size and uniformly spaced across the
boom.
• Calibrate sprayer before use.
• It is suggested that screens be used to protect the pump and to prevent nozzles from
clogging.
• Screens placed on suction side of pump must 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 manufacturers specifications.
Pump
• Use a pump with capacity to:
(1) Maintain sufficient pressure at the nozzle tip to give the required flow rate and
droplet size to provide acceptable coverage of the target crop.
(2) Provide sufficient agitation in tank to keep mixture in suspension - this requires
recirculation of 10% of tank volume per minute.
• Use a jet agitator or liquid sparge tube for agitation.
• DO NOT air sparge.
Cannonball WG
Page 11
For more information on spray equipment and calibration, consult sprayer
manufacturers and state directions. For specific local directions and spray schedules,
consult the current state agricultural directions.
MIXING INSTRUCTIONS
• Prepare no more spray mixture than is required for the immediate operation.
• Thoroughly clean spray equipment before using this product.
• Agitate the spray solution before and during application.
• DO NOT let the spray mixture stand overnight in the spray tank.
• Rinse spray tank thoroughly with clean water after each days use and dispose of
pesticide rinsate by application to an already treated area.
Cannonball WG Alone (no tank mix):
• Add ½-⅔ of the required amount of water to the spray or mixing tank.
• With the agitator running, add Cannonball WG to the tank.
• Continue agitation while adding the remainder of the carrier.
• Begin application of the spray solution after Cannonball WG has completely
dispersed into the mix water.
• Maintain agitation until all of the mixture has been sprayed.
Cannonball WG + Tank Mixtures: Cannonball WG is usually compatible with all tank-
mix partners. To determine the physical compatibility of Cannonball WG with other
products, use a jar test. Using a quart jar, add the proportionate amounts of the
products to 1 quart of water. Add wettable powders and water dispersible granular
products first, then liquid flowables, and emulsifiable concentrates last. After thoroughly
mixing, let stand for at least 5 minutes. If the combination remains mixed or can be
remixed readily, it is physically compatible. Once compatibility has been proven, use
the same procedure for adding required ingredients to the spray tank.
Mixing in the Spray Tank
• Add ½-⅔ of the required amount of water to the spray or mixing tank.
• Allow Cannonball WG to completely dissolve and disperse.
• With the agitator running, add the tank-mix partner(s) into the tank in the same order
as described above.
• Allow the material to completely dissolve and disperse into the mix water. Continue
agitation while adding the remainder of the water to the spray tank.
• Spray the mixture with the agitator running.
• Observe all directions for use, crops/sites, use rates, dilution ratios, precautions, and
limitations which appear on the tank-mix product label.
• Label dosage rate must not be exceeded, and the most restrictive label precautions
and limitations must be followed.
Cannonball WG
Page 12
• This product must not be mixed with any product which prohibits such mixing.
It is the pesticide users responsibility to ensure that all products are registered for the
intended use. Read and follow the applicable restrictions and limitations and directions
for use on all product labels involved in tank mixing. Users must follow the most
restrictive directions for use and precautionary statements of each product in the tank
mixture.
SPRAY DRIFT MANAGEMENT
MANDATORY SPRAY DRIFT
Aerial Applications
• Do not release spray at a height greater than 10 ft above the vegetative canopy,
unless a greater application height is necessary for pilot safety.
• For all applicators, applicators are required to use a medium or coarse spray
droplets size (ASABE S572.1).
• The boom length must not exceed 65% of the wingspan for airplanes or 75% of the
rotor blade diameter for helicopters.
• Applicators must use ½ swath displacement upwind at the downwind edge of the
field.
• Nozzles must be oriented so the spray is directed toward the back of the aircraft.
• Do not apply when wind speeds exceed 10 miles per hour at the application site.
• Do not apply during temperature inversions.
Groundboom Applications
• Apply with the nozzle height recommended by the manufacturer, but no more than 3
feet above the ground or crop canopy.
• For all applications, applicators are required to use a medium or coarser spray
droplet size (ASABE S572.1).
• Do not apply when wind speeds exceed 10 miles per hour at the application site.
• 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
Cannonball WG
Page 13
potential for drift will be greater if applications are made improperly or under unfavorable
environmental conditions.
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 directed 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.
Boom Height Ground Boom
• For ground equipment, the boom must remain level with the crop and have minimal
bounce.
Controlling Droplet Size Aircraft
• Adjust Nozzles Follow nozzle manufacturers directions for setting up nozzles. To
reduce fine droplets, orient nozzles parallel with the airflow in flight.
Release Height-Aircraft
• Higher release heights increase 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.
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
Cannonball WG
Page 14
Drift potential increases with speed. AVOID APPLICATIONS DURING GUSTY WIND
CONDITIONS.
Applicators need to be familiar with local wind patterns and terrain that could affect
spray drift.
Boom-less Ground Applications:
• Setting nozzles at the lowest effective height will help to reduce the potential for
spray drift.
Handheld Technology Applications:
• Take precautions to minimize spray drift.
APPLICATION PROCEDURES
OBSERVE THE FOLLOWING RESTRICTIONS WHEN SPRAYING IN THE VICINITY
OF AQUATIC AREAS INCLUDING LAKES, RESERVOIRS, RIVERS, PERMANENT
STREAMS, MARSHES OR NATURAL PONDS, ESTUARIES, AND COMMERCIAL
FISH FARM PONDS.
• DO NOT apply within 75 ft of bodies of water including lakes, reservoirs, rivers,
permanent streams, natural ponds, marshes, or estuaries.
• Shut off the sprayer when at row ends.
• DO NOT cultivate within 10 ft of aquatic areas as to allow a vegetative filter strip.
• DO NOT apply when weather conditions favor drift to aquatic areas. DO NOT apply
when gusts or sustained winds exceed 10 mph.
• DO NOT apply during a temperature inversion. Mist or fog may indicate the
presence of an inversion in humid areas.
• For perennial crops including tree crops and grapes:
• For all plantings within 150 ft of bodies of water as described above, spray crops
from outside the planting away from the bodies of water.
• Spray last three rows windward of aquatic areas using nozzles on one side only,
with spray directed away from aquatic areas. Adjust or turn off top nozzles on the
side away from the grove/orchard when spraying the outside row. Shut off
nozzles when turning at ends of row or passing tree gaps in the rows.
Ground Application
• Apply in a minimum of 10 gallons of water per acre, unless specified otherwise.
Aerial Application
Aerial Spray Restrictions
Cannonball WG
Page 15
Observe the following restrictions when spraying in the vicinity of aquatic areas
including: lakes, reservoirs, rivers, permanent streams, marshes or natural ponds,
estuaries and commercial fish ponds.
• Use only on crops where aerial applications are indicated.
• Aerial applicators must be in enclosed cockpits.
• Avoid applications under conditions when uniform coverage cannot be obtained or
when excessive drift may occur.
• DO NOT apply by air within 150 ft of lakes, reservoirs, rivers, permanent streams,
marshes, or natural ponds, estuaries, and commercial fish ponds.
• Mount the spray boom on the aircraft so as to minimize the drift caused by wing tip
vortices. Use the minimum practical boom length, and do not exceed 75% of wing
span or rotor diameter.
• Release the spray at the lowest height consistent with pest control and flight safety.
• Avoid applications more than 10 ft above the crop canopy.
• DO NOT apply when weather conditions favor drift to aquatic areas. DO NOT apply
when gusts or sustained winds exceed 10 mph.
• DO NOT apply during a temperature inversion. Mist or fog may indicate the
presence of an inversion in humid areas.
Aerial Spray Precautions
Observe the following precautions when spraying in the vicinity of aquatic areas
including: lakes, reservoirs, rivers, permanent streams, marshes or natural ponds,
estuaries and commercial fish ponds.
• Use the largest droplet size consistent with good pest control.
• Formation of very small droplets may be minimized by appropriate nozzle selection,
by orientating nozzles away from air stream as much as possible, and by avoiding
excessive spray boom pressure.
• Reduce risk of exposure to aquatic areas by avoiding applications when wind
direction is toward the aquatic area.
• Low humidity and high temperatures increase the evaporation rate of spray droplets
and therefore the likelihood on increased spray drift to aquatic area. Avoid spraying
during conditions of low humidity and/or high temperatures.
• For the crops to which aerial applications are allowed, refer to the specific crop
directions for use.
• Apply in a minimum of 5 gallons of water per acre, unless specified otherwise.
Application Through Irrigation Systems (Chemigation)
• Use only on crops for which chemigation is specified on this label.
• Apply this product only through drip, microjet, center pivot, solid set, hand move, and
moving wheel irrigation systems. DO NOT apply this product through any other type
of irrigation system.
Cannonball WG
Page 16
