Cloransulam-methyl is an herbicide that is used for the control of weeds among soya beans and other crops. It is part of the chemical family of triazolopyrimidine sulfonanilides.

Characteristics

Cloransulam-methyl is non-volatile chemical with moderate solubility in water.^[1] The chemical quickly decays via photolysis when in water. In its natural state, it appears as an off white powder with a faint mint smell.^[2]

Cloransulam-methyl's HRAC classification is Group B (global, Aus), Group 2 (numeric), as it is an acetohydroxyacid synthase inhibitor.^[3]

Uses

Cloransulam-methyl can be applied to the surface of the soil near soybean plants to control the growth of broadleaf weeds.^[4] The chemical works by inhibiting amino acid synthesis in the plants.^[1]
