Active ingredient

Triasulfuron

Chemical name

2-(2-chloroethoxy)-N-[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)amino]carbonyl]benzenesulfonamide

Classification

Herbicide / Agrochemical

Formulation

20%WDG, 75%WDG, 75%WP

Biochemistry

Branched chain amino acid synthesis (ALS or AHAS) inhibitor. Acts by inhibiting biosynthesis of the essential amino acids valine and isoleucine, hence stopping cell division and plant growth. Selectivity derives from rapid metabolism in the crop. 

 Mode of action

Selective herbicide, absorbed by the leaves and roots, and rapidly translocated to meristems.

Usage

Control of broad-leaved weeds pre- and post-emergence in wheat, barley and triticale, at 5-10 g/ha.

Mammalian  Toxicology

Oral: Acute oral LD50 for rats and mice >5000 mg/kg. 

Skin and eye: Acute percutaneous LD50 for rats >2000 mg/kg. Mild skin irritant; non-irritating to eyes (rabbits). Non-sensitising to skin (guinea pigs). 

Inhalation: LC50 (4 h) for rats >5.18 mg/l air.
