Propanil 80% DF is a post-emergence, contact herbicide used for the effective control of grassy and broadleaf weeds in rice crops. The dry flowable (DF) formulation is easy to handle, disperses quickly in water, and ensures uniform spray coverage on weed foliage. Propanil acts primarily on the leaf surface, providing reliable control of established weeds without harming the rice crop. It is most effective when applied post-emergence, typically 15-25 days after sowing, when weeds are in their early growth stage.
