Biological Activity

Glufosinate-ammonium is a non-selective, contact herbicide that inhibits glutamine synthetase, leading to ammonia accumulation and disruption of photosynthesis. It controls a broad spectrum of annual and perennial weeds.

Spectrum and Route of Action:

Contact herbicide with limited translocation. Absorbed by foliage and causes rapid chlorosis and necrosis within 2-4 days. No significant soil residual activity. Used in glufosinate-resistant crops as well as for burndown and non-selective weed control.

Scope of Application:

Controls a wide range of weeds including:

• Annual grasses (foxtails, crabgrass, barnyardgrass, annual bluegrass)

• Broadleaf weeds (pigweeds, lambsquarters, ragweed, velvetleaf, morningglory)

• Some perennial grasses and broadleaves at higher rates

Mainly used on:

• Glufosinate-resistant crops (corn, soybeans, cotton)

• Orchards and vineyards (strip treatment)

• Non-crop areas and industrial sites

• Fallow ground and farmsteads

• Vegetable crops (directed spray)

• Nurseries and ornamentals
