The acute oral LD50 in rats was 3150 to 3750mg/kg, and acute LD50>10200mg/kg in rabbits. Rats were fed for 2 years with a daily dose of 1250mg/kg. Carp LC508 ~ 9mg/L (96h). Low toxicity to birds.



Chemical property


Pure products are white crystals. M.p.118 ~ 120 C, vapor pressure 1.33 * 10-4Pa. It is soluble in organic solvents and 48mg/L in water at 20 C. It is not inflammable, explosive and non corrosive. The raw powder is pale white or beige powder, m.p.113 to 115 degrees, with a rotten egg flavor.

It can control annual broad-leaved weeds, grass, sedge and some perennial weeds, such as cattail, barnyard grass, duck tongue grass, knotweed, maidenhair grass and so on. 5-7 days after rice transplantation, 50% WP 3-6g/100m2 was used in the south, 9.8-15g/100m2 in the north and 3-4.5kg in the wet soil. The field water layer is 3 to 5cm, and the water retention is about 10d. To control weeds in dry land, 50% WP 15-22 was used before or after sowing wheat, cotton, peanut and soybean seedlings. 5g/100m2, spray the water 4.5kg on the soil surface.
