Product Introduction

Nicosulfuron is a selective, systemic, post-emergence herbicide in the sulfonylurea family, widely used in corn fields for effective control of annual grassy weeds and certain broadleaf weeds.

Absorbed through the leaves of target weeds, Nicosulfuron is rapidly translocated to meristematic tissues, where it inhibits acetolactate synthase (ALS)—an essential enzyme for the biosynthesis of branched-chain amino acids. This disruption halts protein synthesis, suppresses weed growth, and ultimately causes plant death.

Recommended Usage Methods (Mainly for Corn Fields)

Notes:

• Corn should be conventional varieties; some sweet corn and waxy corn varieties are sensitive to nicosulfuron. A small-area test is required before use.

• Avoid rotary tillage or intertillage shortly after application, as this may affect efficacy.

• Safe for subsequent crops such as wheat, rice, and cotton.
