Biological Activity

Nicosulfuron is a selective sulfonylurea herbicide that inhibits acetolactate synthase (ALS), an enzyme critical for branched-chain amino acid biosynthesis. It provides post-emergence control of grasses and some broadleaf weeds in corn.

Spectrum and Route of Action:

Systemic herbicide rapidly absorbed by foliage and roots and translocated via both xylem and phloem. Susceptible weeds stop growing within hours; chlorosis and necrosis appear within 1-3 weeks. Corn rapidly metabolizes the compound.

Scope of Application:

Controls a wide range of weeds including:

• Annual grasses (green foxtail, giant foxtail, yellow foxtail, barnyardgrass, crabgrass, fall panicum)

• Perennial grasses (johnsongrass, quackgrass, quackgrass)

• Some broadleaf weeds (lambsquarters, pigweeds, ragweed, velvetleaf)

Mainly used on:

• Corn/maize (field corn, seed corn, sweet corn, popcorn)

• Grain sorghum (with appropriate safener)
