For wheat powdery mildew and rust, 50g of rusting emulsion of 50% per acre, or 75g of 15% wettable powder, 60kg~70kg of water, spray prevention at the beginning of the disease; for the total erosion of wheat, per acre Use 20% of rusting emulsifiable concentrate 100g, or 15% of rusting WP WP 150g, watering 50kg~80kg, spray in the ridge of wheat from the start-up period to the jointing stage; for the sheath blight, it can be in the early stage of wheat jointing Use 5% of Jinggangmycin water 100ml ~ 150ml, water 50kg ~ 70kg, sprayed on the base of wheat stem. For the control of wheat bran, it can be used with 50% èšœ èšœ å¯ wettable powder per acre, and 50 kg to 60 kg spray with water. To prevent wheat spiders, use 40% omethoate 25 ml per acre, or 20% dicofol at 50 ml per acre, and spray 30 kg to 40 kg of water to prevent and cure gray locusts and prevent clumps. In addition, attention should be paid to the prevention and control of wheat yellow dwarf disease, bush dwarf disease, wheat leaf bee and underground pests.
The application of chemical herbicides in addition to field weeds has the advantages of rapid and thorough weeding, labor saving and time saving, easy mechanization, low cost, remarkable yield increase and good economic benefits. At present, the commonly used herbicides are dimethyltetrachloride, superstar, benzodiazepine, hummer, shima, etc., hummer and shima can be used to control wild oats and most other monocotyledonous weeds, among which Shima is used for wheat field control. Gramineous weeds can be treated with stems and leaves, and can also remove some broad-leaved weeds such as sorghum and leeks; giant stars, dimethyltetrachloride and benzodiazepines are used to control dicotyledonous broadleaf weeds. The weeds in the spring wheat field are mainly broad-leaved. In the mixed wheat field of giant grass and broad-leaved weeds, 60 ml of 6.9% hormonal emulsifiable concentrate can be added per acre of dimethyltetrachloride or superstar liquid to prevent two types of weeds. The period of use of the herbicide is generally in the green to the beginning. When using, strictly follow the concentration and technical operation rules to avoid phytotoxicity.
