Methabenzthiazuron Chemical Properties,Usage,Production

Chemical Properties

White crystalline solid; melts at 120°C(248°F); insoluble in water [～59 ppm at20°C (68°F)], soluble in organic solvents.

Uses

Methabenzthiazuron is a benzothiazole and urea based herbicide used to control a spectrum of broad-leaved weeds and grasses crops. Methabenzthiazuron works via the inhibition of photosynthetic electron transport chain.

Uses

Selective herbicide.

Definition

ChEBI: Methabenzthiazuron is a member of benzothiazoles.

Health Hazard

Gupta and Singh (1985) investigated thetoxicity of tribunil in calves. Animals treatedwith 500 mg/kg orally developed toxicityin 36–48 hours. The symptoms includedincrease in body temperature, depression,and a progressive decrease in respiration rateand pulse rate. Necropsy findings in animalsthat died showed congestion of the lungs.Other organs affected were liver, kidney,urinary bladder, spleen, heart, and brain.A 75-mg/kg dose produced toxicity after2–3 weeks.

Metabolic pathway

When methabenzthiazuron is presowing applied to the soil of pea fields, three degradation products are detected as (2-benzothiazoyl)urea, 2- (methylamino)benzothiazole and 2- aminobenzothiazole. The latter two amines represent a majority of the soil bound residues.
