In recent years, with the wide application of chemical herbicides in the field, the weed resistance has increased, and the grass phase has changed greatly. The sporadic weeds such as bluegrass, swine fever, sorghum, and savory have developed into wheat. Vicious weeds in vegetable fields. In order to eliminate and control the grass damage, and to ensure a bumper harvest next year, the following countermeasures are proposed:
First, rapeseed field chemical weeding. (1) Soil treatment: use 70-100 ml of 50% acetochlor EC per acre, spray 40 kg of water before seedlings in rapeseed; or 2-3 days before transplanting rapeseed, use 41% of Nanda water 30 - 40 ml spray on water 40 kg. (2) Stem and leaf treatment: a field dominated by monocotyledonous weeds, in the second to third leaf stage of weeds, using 900.100% of oil and stalks of 900.5% per acre, or 30% of 10.8% of high-efficiency grasses, or 5% fine grass can be 30-35 ml of emulsifiable concentrate and spray 50 kg of water.
Fields dominated by dicotyledonous weeds are sprayed with 50% high-gram 30-35 ml per acre and 50 kg of water.
Fields mixed with single and double cotyledons, 7-10 days after transplanting, using 17.5% oil grass double clear 90-100 ml per acre, or 90% Wones emulsifiable concentrate 45 ml, before transplanting rapeseed or transplanting 5 After a day, spray 50 kg of water.
Second, chemical weeding in wheat fields. (1) Soil treatment. 50-100 ml of 60% butachlor EC was applied per acre, and 50 kg of water was sprayed before the sowing of the wheat. (2) Stem and leaf treatment. Fields dominated by grass weeds, with 50% hyperosmolar 125 g or 6.9% thrips 40-60 ml per acre, evenly sprayed with 40 kg of water in the three to five-leaf stage of wheat; For weed-based fields, use 20% per acre to make 40-50 ml of its aroma oil or 10 g of a 10% superstar, and spray 40 kg of water on the three to five-leaf stage of wheat. In the field of single and double cotyledon mixed fields, 80% of its aroma oil and 50% of 6.9% Hummer were used per acre, and 40 kg of water was sprayed from the true leaf stage of wheat to the jointing stage.
Third, pay attention to matters. When applying the medicine, it should choose no wind and no rain; the wheat field should be banned with metsulfuron-methyl, chlorsulfuron and its compound preparations;
