herbicide weed killer
Agricultural Herbicides Prometryn 50% SC used in cotton fields
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.
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.
Both amphibious and drought selective pesticides are three azine herbicides. It has internal absorption. It can be absorbed from roots, or seeped into plants from stems and leaves, transported to green leaves to inhibit photosynthesis, and weeds become green and dry and die. It is suitable for rice, wheat, soybean, cotton, sugarcane, fruit tree, vegetable and other crops. 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.
