Certify that peas, location. or irrigation conditions are listed on the product label you purchase. Adjust rates depending on expected temperatures according to label instructions. Do not apply if temperature may exceed 90 F within 24 hours. Maintain spray pressure below 40 psi to minimize drift from target field. Higher rate will be required during cool weather.
Some evidence exists that early morning applications are safer to crop than afternoon applications.
Do not feed treated peas or vines to livestock. Do not spray when air temperatures exceed 90 F or when peas are stressed from lack of moisture. Do not use on coarse, sandy, or shallow soils. Avoid applying more than 0.5 inch of irrigation within 1 month after metribuzin application or crop injury may occur. Warm temperatures or tank-mixes with bentazon have caused injury west of Cascades.
