MODE OF ACTION
Topshot 60 OD is a combination of two active i.e Cyhalofop Butyl and Penoxsulam with two different modes action. Penoxaulam: Belongs to HRAC Group: B – Inhibition of acetolactate synthase ALS (acetohydroxyacid synthase AHAS).
Cyhalofop-butyl: Belongs to HRAC Group : A – Inhibition of acetyl CoA carboxylase (ACCase)
Cyhalofop-butyl is a systemic herbicide that interferes with fatty acid synthesis within grasses. By depriving the plant of needed lipids, cell division at the plant meristem is inhibited.
