Agricultural weed killer Tribenuron methyl 75% WDG sulfonylurea herbicide


 
 
Toxicity
 
Acute oral LD50 > 5000 mg / kg in female and male rats, acute percutaneous LD50 > 5000 mg / kg in rats and 2000mg / kg in rabbits, and acute inhalation of LC50 > 5mg / L in rats (4h). It was slightly irritating to eyes, but disappeared after 24 hours; no irritation to skin; no allergy to guinea pig skin. Micronucleus test showed that bensulfuron-methyl had no mutagenic effect on somatic cells, testicular chromosome aberration test showed that bensulfuron-methyl had no genetic toxicity on germ cells, and no teratogenicity was found in rats. Rainbow trout LC50>1000mg/L (96h), Daphnia LC50720mg/L (48h). Quail acute oral LD50>2250mg/kg. Bee LD50>0.1mg/ only earthworm LC50>1200mg/kg soil.
 
 
 
Chemical property
 
This product is white solid. M.p.141 C, vapor pressure 0.036 * 10-3Pa (25 C). The solubilities of acetone, acetonitrile, carbon tetrachloride, ethyl acetate and hexane in organic solvents were 43.8 mg/L, 54.2 mg/L, 3.12 mg/L, 17.5 mg/L and 0.028 mg/L, respectively. The partition coefficient (octanol / water) was 0.36 (pH=7). It is stable in storage at room temperature, stable in light, hydrolyzed at 45 C, stable in pH 8 ~ 10, but hydrolyzed rapidly at pH < 7 or > 12. The half-life of soil is 1 to 7d.
 
 
 
Purpose
 
Sulfonylurea herbicides inhibit acetolactate synthase, cell division and shoot and root growth. The roots and leaves of plants were absorbed and died within 14d. It can be used to control broadleaf weeds effectively in cereal crops. Spraying 0.1-0.2g/100m2 to control broad-leaved weeds in wheat field has good control effect (adding surfactant can increase control effect).
It is used as herbicide in wheat field. It can effectively control annual broad-leaved weeds, such as mustard, shepherd's purse, barley grass, Herba cider, Herba cider, Chenopodium album, amaranth and so on.
 
 
 

Active ingredient Tribenuron-methyl
Chemical name methyl 2-[[(4-methoxy-6-methyl-1,3,5-triazin-2-yl)-methylcarbamoyl]sulfamoyl]benzoate;
Classification Herbicide
Formulation 75%
Biochemistry Affects sensitive weeds through inhibition of the enzyme acetolactate synthase (ALS). Inhibition of ALS leads to the rapid cessation of cell division and subsequent growth processes in plants.
Mode of action Selective, post-emergence herbicide, acting primarily through foliar uptake, with little or no soil activity. Symptoms of chlorosis appear in affected weeds in days with necrosis and death occuring after 10-25 days under optimal conditions.
Usage Post-emergence control of broad-leaved weeds in cereal crops, including wheat, barley, oats, rye and triticale, at 7.5-30 g/ha
Mammalian Toxicology Oral Acute oral LD50 for rats >5000 mg/kg. Skin and eye Acute percutaneous LD50 for rabbits >5000 mg/kg. Non-irritating to skin and eyes (rabbits). Mildly sensitising to skin (guinea pig maximisation test), but not likely to be a dermal sensitisation risk to humans. Inhalation LC50 (4 h) for rats >5.0 mg/l air. NOEL (2 y) for rats 25 ppm diet; (18 mo) for mice 200 ppm diet (25 mg/kg b.w. daily); (1 y) for dogs 250 ppm diet (8.2 mg/kg b.w. daily); (90 d) for rats 100, for mice 500, for dogs 500 mg/kg diet. ADI 0.01 mg/kg Other Not genotoxic. Toxicity class WHO (a.i.) U; EPA (formulation) III EC classification R43
