Mode of Action
Understanding the mechanism of PIROJ
Pyrazosulfuron Ethyl inhibits the acetolactate synthase (ALS) enzyme, blocking the biosynthesis of essential branched-chain amino acids required for weed growth. The herbicide is absorbed through both roots and shoots and translocated to actively growing tissues. This disrupts cell division and growth processes, causing weed growth arrest followed by yellowing and eventual death.
