FMC Authority (Sulfentrazone 39.6% SC) Pre-Emergence Herbicide

FMC Authority (Sulfentrazone 39.6% SC) is a highly effective selective pre-emergence herbicide designed to control a broad spectrum of weeds in agricultural crops. It is applied within 0 to 3 days after sowing and provides long-lasting residual control for up to 4–6 weeks.

Sulfentrazone 39.6% SC

⚙️ Mode of Action

Sulfentrazone belongs to the aryl triazolinone group and inhibits the PPO (Protoporphyrinogen oxidase) enzyme in weeds. This leads to accumulation of toxic compounds, causing cell membrane disruption, rapid desiccation, and death of weed seedlings.
