Pasture

PASTURE — TEAMMATE INSTRUCTIONS WHAT THIS IS Herbicide application to weed growth in active or recently active pasture — land used for grazing by horses, cattle, sheep, goats, or other livestock. This is one of the highest-responsibility spraying locations due to direct animal contact with treated vegetation and soil. UNIQUE CONSIDERATIONS - Livestock will eat treated vegetation unless physically excluded — product selection must account for animal ingestion. - Different livestock species have different sensitivities — products safe for cattle pasture may not be safe for horse pasture. - Grazing restrictions (days animals must be removed from treated area) vary by product — know the restriction before you spray. - Pasture weeds include species that are toxic to livestock (larkspur, locoweed, death camas) — killing these weeds can temporarily increase toxicity risk if animals consume wilting treated plants before they fully die. - Some pasture herbicides can contaminate hay if treated forage is cut and baled — note this if the pasture is also used for hay production. PRODUCT RESTRICTIONS - Use only products explicitly labeled for pasture use with the specific livestock species present. - Know the grazing restriction interval for the product and livestock combination. - Products containing aminopyralid or clopyralid persist in manure and can damage garden crops if composted manure is used — note this for clients who compost. - Do not use non-selective herbicides in active pasture — they will kill the forage. ENVIRONMENTAL & LEGAL FLAGS - Colorado CDA requires documentation of livestock species, grazing restriction interval, and product used for all pasture applications. - Noxious weed management in pasture may be required by county weed district — note species and report if required. - Pasture near waterways requires aquatic buffer compliance — see Retention Pond term. - Organic livestock operations cannot have synthetic herbicides applied to their pasture — confirm with client if there is any organic certification. FIELD RULES — DO - Confirm livestock species present BEFORE selecting product. - Communicate grazing restriction interval to the client BEFORE spraying. - Walk the pasture and identify target weed species, desirable forage, and any toxic weed species. - If toxic weeds are present, warn the client about temporary increased toxicity of wilting treated plants. - Coordinate with the client's grazing schedule. FIELD RULES — DO NOT - Do not spray pasture without confirming livestock species and grazing restrictions. - Do not assume "cattle safe" means "horse safe" — they are different. - Do not spray near stock water tanks, troughs, or ponds without buffer distance. - Do not spray if livestock cannot be excluded for the required restriction period. RECORD-KEEPING NOTES Document livestock species present, grazing restriction interval, product and rate, approximate area treated, target weed species, and any toxic weed species observed. Note client communication of grazing restrictions and coordination with grazing schedule.
