Cyclosulfamuron Use and Manufacturing

Sulfonylurea herbicide, acetolactate synthase inhibitor. After the agent is absorbed by the weeds, it is transmitted through the plant, the weeds stop growing, the leaves become green, and usually die completely after a few weeks. It is used to control annual and perennial broad-leaved weeds and sedge weeds in rice, wheat, barley and lawns. Such as the third floor of perennial water in paddy fields, water chestnuts, wild water chestnuts, dwarf cunts, fireflies; annual heterotypic sedges, chickweeds, moss grasses, rhododendrons, knotweeds and mother grass weeds; pretreatment of wheat fields Control blue glass chickweed, shepherd~"s purse, medicinal cone corydalis, one year out of indigo, setaria, arabinosa, etc., post-seasonal seedling treatment of wild European white mustard, corn poppy, shepherd~"s purse, medicinal cone Corydalis, ivy, granny, etc., post-emergence treatment in spring to prevent blue glass chickweed, wild white mustard, shepherd~"s purse, medicinal cone corydalis, swamp, stalk, etc. It is particularly effective in preventing pigs. Used for paddy field application 2-15 days after transplanting rice, dosage 45-60g/hm2; direct application paddy field application within 12 days, dosage 10-40g/hm2; post-seed treatment of wheat field, use dosage 25-50g/hm2, Spring application is better than autumn, and the application effect in late spring is better than early spring. During the post-emergence treatment in spring, some vegetable oils are used as adjuvants at a dosage of 25g/hm2. It is applied after the seedlings in autumn and the dosage is 75～100g/hm2. Has been provisionally registered in my country~"s rice fields.
