Autumn sowing is one of the critical periods for controlling winter wheat diseases, weeds and weeds. It can not only control the damage of pests and weeds, but also reduce the source of diseases and weeds in winter and reduce the use of chemical pesticides. Seed drug treatment Pre-sowing winter wheat seed coating or chemical seed dressing treatment is the main measure for preventing and controlling underground pests and winter wheat propagation, soil-borne diseases, and powdery mildew, leaf rust, wheat spiders, and planthoppers in autumn. Safeguard the key measures for the whole seedlings and strong seedlings of wheat. The districts should scientifically adjust the types of coating or seed dressing agents according to the occurrence of local pests and diseases to ensure that the “white seeds†of winter wheat do not fall to the ground. For coating insecticides and fungicides, 30.8% of imidacloprid and 1% tebuconazole were used as the seed coating agent, and 6 ml per kilogram of seed was used; 600 g/l of imidacloprid suspension seed coating was used to compound 60 g/L of tebuconazole. The seed coating dosage of suspended seeds is 4.8g/0.5g for each kilogram of seed; Thiamethoxam 70% seed treatment can be used for dispersible granules; 60g/L of tebuconazole is used as seed coating agent; 4g, 0.5g; 50% phoxim EC for seed dressing insecticide, 50% carbendazim wettable powder for germicide, 0.2% seed weight, insecticide and fungicide Mix liquid seed dressing, stuffy stuffy for 4~6 hours, dry and sow. Phoxim dressing should pay attention to dark operation. Seedling pests and weed control The poor resistance of weeds in autumn wheat fields is a favorable time for chemical weed control. Chemical weeding can be carried out in accordance with the occurrence of weeds in the field. Chemical weeding should be carried out after the wheat tillering stage and during the weeding stage of 2 to 4 leaves. The use of 10% tribenuron-methyl wettable powder 10 g or 75% tribenururon-methyl dry suspension agent per acre can prevent and treat wheat fields dominated by weeds such as sow plant and leeks. Grass-based wheat fields can be treated with 70% Clozasulfuron water dispersible granules 3 to 4 grams per mu. When the wheat stubble and the planthopper are serious in the wheat field and reach the prevention and control index, it is necessary to conduct chemical prevention and control in time to prevent damage to the wheat seedlings and transmission of the virus disease.
