Pendimethalin is an excellent dry field crop for selective post- emergence soil treatment of herbicides . Weeds absorb the agent through the sprouting sprouts, and the agent that enters the plant binds to tubulin and inhibits mitosis of plant cells. Cause weeds to die.
Pendimethalin can be widely used in weeding of various crop fields such as corn, soybean, peanut, cotton, direct seeding dry rice, potato, tobacco, and vegetables. At present, pendimethalin is the world's third largest herbicide, and its sales are second only to the herbicides glyphosate and paraquat. It is also the world's largest selective herbicide.
Upland rice, rice dry nursed field: use 150-200 ml of 33% pendimethalin oil per acre, 15-20 kg of water, and spray the topsoil before seeding.
Direct cotton: 150-200 ml of 33% pendimethalin per acre, 15-20 kg of water, and topsoil spray before or after sowing. Due to the dry weather in the northern cotton area, in order to ensure the herbicidal effect, it is necessary to mix 3-5 cm after application.
Corn: (1) Spring corn in the northeast area is treated with 33% dimethoprim EC 200-300 ml per acre, 15-20 kg water, and the topsoil spray before emergence. The application should be carried out within 5 days after sowing, and it is easy to cause phytotoxicity to corn after too late application. (2) Summer corn is used with 33% diamyl emulsifiable concentrate 150-200 ml per acre, 15-20 kg with water, and the topsoil spray before emergence. Summer corn planted in no-tillage in North China, first watered in the head water after sowing, and applied within 2 days after watering, it is easy to produce phytotoxicity after applying too late.
Soybeans, peanuts: (1) Spring soybeans, spring peanuts, use 33% of pendimethalin EC-200-300 ml per acre, 15-20 kg of water, mix with soil after soil preparation, and then sow. (2) Summer soybeans, summer peanuts, use 150% of pendimethalin emulsifiable concentrate 150-200 ml per acre, 15-20 kg of water, and 1-2 days after seeding, the topsoil spray is easy to produce phytotoxicity.
Potato: 150-200 ml of 33% pendimethalin emulsifiable concentrate, 15-20 kg of water, and topsoil spray before emergence.
Live vegetable fields: garlic, ginger, carrots, peppers, leeks, shallots, onions, celery, medlar and other live fields, using 33% pendimethalin emulsifiable concentrate 100-150 ml, 15-20 kg of water, after sowing soil Topsoil spray.
Transplanting vegetable fields: transplanted fields of pepper, tomato, leeks, green onions, onions, celery, cauliflower, cabbage, cabbage, eggplant, etc., using 100% of penicillin emulsifiable concentrate, 100-150 ml, and water of 15-20 kg. Topsoil spray 1-2 days before transplanting.
Rapeseed field: (1) Live rapeseed field, using 33% pendimethalin emulsifiable concentrate 100-150 ml, 15-20 kg of water, after seeding soil, topsoil spray; (2) transplanting rapeseed field, using 33% of mu Pentaerythritol EC 150-200 ml, water 15-20 kg, 1-2 days before transplanting topsoil spray.
Amaranth: After the harvesting wound is healed, the old amaranth is used with 100% to 150 ml of 33% pendimethalin and 15-20 kg of water, evenly sprayed.
