Classification | Herbicide / Agrochemical | ||
Biochemistry | Branched chain amino acid synthesis (ALS or AHAS) inhibitor. Selectivity in soya beans and peanuts is attributed to rapid detoxification via demethylation and glycosylation (B. Tecle et al., Proc. 1997 Br. Crop Prot. Conf. - Weeds, 2,605). | ||
Mode of action | Post-emergence herbicide, absorbed through both foliage and roots and translocated to growing points. Plants wilt and turn brown. | ||
