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
|
||||
For terrestrial uses: This pesticide is toxic to fish and aquatic invertebrates and may contaminate water through runoff. This product has a 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 product. Drift and runoff may be hazardous to aquatic organisms in water adjacent to treated areas.
|
||||
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 rinsate.
|
||||
For aquatic uses: This pesticide is toxic to fish and aquatic invertebrates. Waters treated with this product may be hazardous to aquatic organisms.
|
||||
Treatment of aquatic weeds and algae can result in oxygen loss from decomposition of dead algae and weeds. This oxygen loss can cause fish and
|
||||
invertebrate suffocation. To minimize this hazard, do not treat more than 1/2 of the water body to avoid depletion of oxygen due to decaying
|
||||
vegetation. Wait at least 14 days between treatments. Begin treatment along the shore and proceed outwards in bands to allow fish to move into
|
||||
untreated areas. Consult with the State or local agency with primary responsibility for regulating pesticides before applying to public waters, to
|
||||
determine if a permit is required.
|
||||
Certain water conditions including low pH (S6.5), low dissolved organic carbon (DOC) levels (3.0 mg/L or lower), and "soft" waters (i.e., alkalinity less
|
||||
than 50 mg/L), increases the potential acute toxicity to non-target aquatic organisms.
|
||||
For applications in waters destined for use as drinking water, those waters must receive additional and separate potable water treatment. Do not
|
||||
apply more than 1 .0 ppm as metallic copper in these waters
|
||||
PHYSICAL OR CHEMICAL HAZARDS
|
||||
Do not use, pour, spill or store near heat or open flame.
|
||||
CHEMIGATION PROHIBITION
|
||||
Do not apply this product through any type of irrigation system.

|
||||
SPRAY DRIFT MANAGEMENT
|
||||
A variety of factors including weather conditions (e.g., wind direction, wind speed, temperature, relative humidity) and method of
|
||||
application (e.g., ground, aerial, airblast, chemigation) can influence pesticide drift. The applicator must evaluate all factors and make
|
||||
appropriate adjustments when applying this product.
|
||||
Droplet Size
|
||||
Apply only as a medium or coarser spray (ASAE standard 572) or a volume mean diameter of 300 microns or greater for spinning
|
||||
atomizer nozzles.
|
||||
Wind Speed
|
||||
Do not apply at wind speeds greater than 15 mph. Only apply this product if the wind direction favors on-target deposition
|
||||
(approximately 3 to 10 mph), and there are no sensitive areas within 250 feet downwind.
|
||||
Temperature Inversions
|
||||
If applying at wind speeds less than 3 mph, the applicator must determine if a) conditions of temperature inversion exist, or b) stable
|
||||
atmospheric conditions exist at or below nozzle height. Do not make applications into areas of temperature inversions or stable
|
||||
atmospheric conditions.
|
||||
Other State and Local Requirements
|
||||
Applicators must follow all state and local pesticide drift requirements regarding application of copper compounds. Where states have
|
||||
more stringent regulations, they must be observed.
|
||||
Equipment
|
||||
All aerial and ground application equipment must be properly maintained and calibrated using appropriate carriers or surrogates.
|
||||
Additional requirements for aerial applications:
|
||||
- The boom length must not exceed 75% of the wingspan or 90% of the rotor blade diameter.
|
||||
- Release spray at the lowest height consistent with efficacy and flight safety. Do not release spray at a height greater than 10 feet
|
||||
above the crop canopy unless a greater height is required for aircraft safety.
|
||||
- When applications are made with a crosswind, the swath must be displaced downwind. The applicator must compensate for this
|
||||
displacement at the up and downwind edge of the application area by adjusting the path of the aircraft upwind.
|
||||
Additional requirements for ground boom application:
|
||||
Do not apply with a nozzle height greater than 4 feet above the crop canopy."
|
||||
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 State or Tribal agency responsible for pesticide regulation.

Helena Copper-Z 4/4 can be used to control Algae in impounded waters, lakes, ponds and reservoirs, for algae and potomogeton pond weed control
|
||||
in waters destined for use as drinking water or irrigation conveyance systems and for fungicidal control of specific diseases on crops.
|
||||
DIRECTIONS FOR USE
|
||||
This liquid copper sulfate product is easy and ready to use to control algae in slow moving or quiescent bodies of water including: golf course,
|
||||
ornamental, fish, irrigation and fire ponds; fresh water lakes and fish hatcheries; water destined for drinking water and non-potable water reservoirs
|
||||
and associated waters (river, streams, bays and coves); and crop and noncrop irrigation conveyance systems (canals, laterals and ditches). Waters
|
||||
treated with Copper-Z 4/4 may be used for swimming, fishing, drinking (after further treatment), livestock watering or irrigating turf, ornamental plants
|
||||
or crops.
|
||||
Copper-Z 4/4 effectively controls many species of both filamentous (mat forming green algae) and planktonic (single cell blue-green) algae. The
|
||||
rate of copper sulfate and control are affected by algae species, water hardness, water temperature, amount of algae present, as well as whether
|
||||
water is clear, turbid, flowing, or static. Preferably water should be clear and above 60 DEGREES F, with treatment made in the late morning on a
|
||||
sunny day. Static water usually requires less copper sulfate than flowing water. The harder the water, the higher the required rate of copper sulfate.
|
||||
When mats of filamentous algae are floating, the surface of these mats should be sprayed. Algae will absorb the copper sulfate within hours after
|
||||
treatment, and death should be evident within 3 to 5 days. If there is some doubt about the concentration to apply, begin with a lower rate and
|
||||
increase the rate until the algae are killed. (A few algae species are resistant to copper sulfate treatment and may not be killed). Repeat treatments
|
||||
may be needed to keep algae under control to the desired levels.
|
||||
Treatment of algae can result in oxygen loss form the water caused by the decay of dead algae. This loss can cause fish suffocation. To minimize
|
||||
this hazard, treat 1/3 to 1/2 of the water area in a single operation and wait 14 days between treatments. Begin treatments along the shore and
|
||||
proceed outwards in bands to allow fish to move into untreated water. Trout and other species of fish may be killed at application rates
|
||||
recommended on this label, especially in soft and acid waters.
|
||||
1. For Algae Control in Reservoirs, Lakes, Ponds, Impounded Waters:
|
||||
When to apply: Early treatment is essential for most satisfactory algae control at the lowest rate levels. Early growth is usually confined to
|
||||
shallower shore areas. Begin treatment when not over 5 to 10% of the water surface area is covered with algae growths which is usually
|
||||
nearest the shoreline. Delaying treatment until heavy algae growths are present usually requires a higher rate and may result in fish
|
||||
distress or death since rapid decomposition of heavy growths greatly reduces the oxygen content of the water. Several repeat treatments
|
||||
are necessary to control algae each season.
|
||||
How to apply Copper-Z 4/4: Dilute the recommended amount of this product in sufficient water to thoroughly and uniformly spray the water
|
||||
surface including any floating algae mats.
|
||||
Rates to Control Algae: First, accurately determine the surface acres of water to be treated at one time and multiply this by the average
|
||||
depth in feet of this water area to determine the acre feet of water to be treated. [One acre foot = one surface acre (43,560 sq. ft.) x one
|
||||
foot depth.]
|
||||
Each acre foot of water contains 326,000 gallons, or 2,720,000 pounds of water. Since recommended concentrations are normally given in parts per
|
||||
million (ppm), it will first be necessary to convert the value in parts per million to a decimal equivalent. For example, 2 ppm is the same as 0.000002
|
||||
when used in this calculation. Therefore, to calculate the amount of Copper Sulfate Pentahydrate to treat 1 acre-foot of water with 2 ppm Copper
|
||||
Sulfate, the calculation would be as follows:
|
||||
0.000002 x 2,720,000 = 5.44 Ibs. Copper Sulfate Pentahydrate.
|
||||
To obtain the correct amount of Helena Copper-Z 4/4 divide 5.44 Ibs.
|
||||
by 1.53 Ibs. which equals 3.5 gallons of Copper-Z 4/4. The rates of
|
||||
Copper-Z 4/4 per acre foot of water to control specific algae species
|
||||
are given later in the label.
|
||||
Secondly, if the problem algae genera is known, use the table below and its equivalence to determine the approximate rate of this product needed to
|
||||
control that genera. If the genera of either filamentous or planktonic algae is not known, apply 6.2 - 9.3 quarts of this product per acre foot of water,
|
||||
using the lower rate in soft water and the higher rate to hard water. For control of bottom-attached algae Chara and Nietella use 9.3 -12.8 quarts
|
||||
per acre foot of water to be treated. If control is not achieved or in very adverse waters, a higher rate may be needed. DO NOT EXCEED LABELED
|
||||
RATES.

2. Algae Control in Rice Fields: Apply 6.3 to 7.0 gallons Copper-Z 4/4 liquid per acre foot of water to the water surface as a surface spray.
|
||||
Application should be made when the algae has formed on the soil surface but prior to rising of the water surface.
|
||||
3. Tadpole Shrimp Control in Rice Fields: Apply 3.1 to 6.3 gallons of Copper-Z 4/4 liquid per acre to the flooded field at any time the pest appears
|
||||
between planting time and until the seedlings are rooted and have emerged through the water surface. The lower rate should be used when the
|
||||
water depth and flow rate are minimal and higher rate should be used when the water depth and flow are at a maximum.
|
||||
RESTRICTIONS AND LIMITATIONS
|
||||
Fish Ponds and Fish Hatcheries (Aquaculture): Maximum treatment level is 0.4 ppm of metallic copper (2.8 gallons of Copper-Z 4/4 per acre foot of
|
||||
water).

DRIP SYSTEM APPLICATION
|
||||
FOR USE IN CANALS, DITCHES, LATERALS AND OTHER IRRIGATION CONVEYANCE SYSTEMS
|
||||
• Copper-Z 4/4 should be applied as soon as algae or Hydrilla begins to interfere noticeably with normal delivery of water
|
||||
(clogging of lateral headgates, suction screens, weed screens and siphon tubes). Delaying treatment could perpetuate the
|
||||
problem causing massing and compacting of plants. Heavy infestations and low flow conditions increasing water flow rate
|
||||
during application may be necessary.
|
||||
• Prior to treatment it is important to accurately determine water flow rates. In the absence of weirs, orifices, or similar
|
||||
devices which give accurate water flow measurements, volume of flow may be estimated by the following formula:
|
||||
Average Width (feet) x Average Depth (feet) x Velocity* (feet/second) x 0.9 —
|
||||
Cubic Feet per Second (C.F.S.)
|
||||
"Velocity is the time it takes a floating object to travel a given distance. Dividing the distance traveled (feet) by the time
|
||||
(seconds) will yield velocity (feet/second). This measurement should be repeated at least three times at the intended
|
||||
application site and then averaged.
|
||||
• After accurately determining the water flow rate in C. F. S. or gallons/minute, find the corresponding Copper-Z 4/4 drip
|
||||
rate on the chart below.

• Calculate the amount of COPPER-Z 4/4 needed to maintain the drip rate for a period of 3 hours by multiplying Qts./Hr. x
|
||||
3; ml/Min. x 180;orFI. Oz./Min. x 180. Dosage will maintain 1.0 ppm metallic copper concentration in the treated water
|
||||
for the 3 hour period. Introduction of the chemical should be made in the channel at weirs or other turbulence-creating
|
||||
structures to
|
||||
promote the dispersion of chemical.
|
||||
• Pour the required amount of COPPER-Z 4/4 into a drum or tank equipped with a brass needle valve and constructed to
|
||||
maintain a constant drip rate. Use a stop watch and appropriate measuring container to set the desired drip rate. Readjust
|
||||
accordingly if flow rate changes during the 3 hour treatment period.
|
||||
• Distance of control obtained down the waterway will vary depending upon density of vegetation growth. Treatment
|
||||
period may have to be extended up to 6 hours in areas where control may be difficult due to high flows or significant
|
||||
growth. Periodic maintenance treatments may be required to maintain seasonal control.
|
||||
• Wait 14 days before retreatment.
|
||||
FOR FUNGICIDE USE
|
||||
Use as directed below. Depending on the equipment used and the specific crop, the volume applied per acre will differ. For high volume sprays,
|
||||
use from 25 to 100 gallons per acre (GPA). For concentrate ground sprays, apply form 20 to 50 GPA. For aerial spraying, 3 to 15 GPA are
|
||||
commonly used.
