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]
