sethoxydim (Poast)

Rate 0.19 lb ai/a (1pint/a)

Time Apply to actively growing wild proso millet.

Remarks See label for crops, size of grass, and sites sethoxydim may be used on and for specific rates. Apply with 2 pints/a crop oil concentrate. Acts very slowly, taking at least 2 weeks and often 4 weeks to show herbicide effectiveness. Do not apply to stressed grasses.
