F.p.: >200 ℃ (Cleveland open cup)
Toxicology: Oral: Acute oral LD50 for rats and mice >5000 mg/kg.Skin and eye Acute percutaneous LD50: for rats >2000 mg/kg.
Application:Biochemistry: Branched chain amino acid synthesis (acetolactatesynthase or ALS) inhibitor. Acts by inhibiting biosynthesis of theessential amino acids valine and isoleucine, hence stopping celldivision and plant growth. Crop selectivity derives from selectivemetabolism (pyrimidine-5-hydroxylation, followed by conjugation withglucose). Mode of action: Selective systemic herbicide, absorbed by thefoliage and roots, with rapid translocation to the meristematic tissues.Uses: Selective post-emergence control in maize of annual grass weedsincluding Setaria, Echinochloa, Digitaria, Panicum, Lolium,and Avenaspp., broad-leaved weeds including Amaranthus spp. and Cruciferae, andperennials such as Sorghum halepense and Agropyron repens. Applied at35-70 g/ha.
Packing: 25KG drum, other packing material available as per customers requirements.
