Selective Systemic Herbicide
PYRAZOSULFURON ETHYL 10% WP
A selective systemic herbicide for the control of sedges, grasses, and broad-leaved weeds in transplanted rice. It provides both pre and early post-emergence control with extended residual activity.
Active: Pyrazosulfuron Ethyl
Formulation: 10% WP
Crop: Transplanted Rice
Mode of Action
Pyrazosulfuron ethyl inhibits the acetolactate synthase (ALS) enzyme, effectively blocking the synthesis of branched-chain amino acids. This action stops cell division in meristematic tissues, leading to growth cessation and plant death within 10-15 days.
