Performance selective pre-emergence soil treatment amide herbicides. Product name is cable, grass is not green. Has moderate irritative effects on rabbit skin and eyes. Soybeans, corn, peanuts, etc. have greater resistance to alachlor.
Alachlor can effectively control most annual grasses and some dicotyledonous weeds. It can also be used for weeding vegetables such as cotton, sugar cane, rapeseed, tobacco, onion and radish. In soybean fields, soil treatment can be done before sowing or before sowing. In sand, loam and clay soils, 43% of alachlor EC was used in the order of 3.75-4.5, 4.5-6.0, and 6.0-6.75 liters per hectare. When the density of weeds is high or the content of organic matter is high, the upper limit should be adopted. 450-600 liters of water per hectare, evenly spraying the surface. Rain weeds in medium-humidity soil or after application ensure weed control. In arid soils, soil should be mixed with light soil so as not to harm soybean sprouts. In order to avoid broad-leaved grassland, alachlor should be mixed with or used with herbicides for broad-leaved grasses. In the peanut field, use 2.5% to 3.75 kg of 43% Alachlor EC per hectare, uniformly mix the soil immediately after spraying, and then sow the peanuts. The effect is significant on peanuts, crabgrass, amaranth, alfalfa, alfalfa and other peanuts. . After the application of mixed soil covered plastic film (the amount of drug can be appropriately reduced), and then sowing peanuts, not only weeding effect is good, and significant increase in production. In the corn field, before or after sowing, the soil treatment with 43% Alachlor EC 25-4.5 kg/ha, the herbicidal effect is good, if mixed with Atrazine, the efficacy is better. The amount of vegetable land is 200 ml/mu. After the surface is evenly sprayed, tomatoes, peppers, onions, radishes and other crops can be transferred or sown. Due to the onset of tumors, in 1987 the United States regulated Alachlor as a "limited use" herbicide. That is to say, only those who are certified by the certificate, or under their guidance, should use it on the prescribed crop. It requires mechanical loading and unloading and spraying. It is forbidden to use artificial signal-bearers during aircraft spraying.
