The mycelium and the attached conidia in the diseased leaf tissue in the field surface and in the corn stalks can overwinter and become the source of the initial infection in the second year. In the corn growing season, the wintering bacterium produces spores. Rainwater or air flow spreads to the corn leaves, suitable for germination and invasion under the conditions of temperature and humidity. The bacteria spreads rapidly after invading. After about 14 days, local wilting and tissue necrosis can be caused, resulting in the formation of dead spots, under humid climate conditions. A large number of conidia can be produced on the lesions and spread with the air flow for several re-infestations, causing disease epidemics. Fields have seen lesions in the field: in northern China, spring maize in early June and summer maize in mid-July. Prevention and control methods should adopt comprehensive prevention and treatment measures such as selection of resistant and disease-resistant varieties, strengthening cultivation and management, and focusing on pesticide application. 1. Use resistant (resistant) varieties and corn hybrids resistant to large and small spot diseases. 2. Implement a crop rotation system to avoid corn cropping, deep-falling soil in the autumn, deep-buried diseased plants, and sterilization sources; corn stalks used as fuel, which can be treated as soon as possible after the beginning of spring, and can also be used to treat corn borer; Full maturity, straw fertilizer is best not applied in corn. 3. Improve cultivation techniques and enhance corn disease resistance Early sowing of summer maize can significantly reduce the incidence of disease. Appropriate application of phosphate fertilizer, pay attention to the reasonable combination of nitrogen, phosphorus and potassium fertilizer, reapply horn flare fertilizer, implement corn and soybean intercropping, or with wheat and peanut Intercropping with sweet potatoes, etc., wide and narrow row planting; rational irrigation, low-lying attention to field drainage. 4. Spraying control Due to the limitation of objective conditions such as high and close planting of corn plants, it is possible to focus on the control of crops and intercropping fields and other high-yielding experimental fields. Generally, prevention and treatment before disease expansion can be performed before and after corn tasseling, when the field strains When the rate is over 70% and the diseased leaf rate is about 20%, spraying is started. The types of agents with better control effects are: 50% carbendazim WP, 50% amidicarb WP or 90% SON Zinc, add water 500 times, or 40% grams of loquat cream 800 times spray. The use of liquid medicine per acre 50 kg to 75 kg, spray every 7 days to 10 days 1, a total of 2 times to 3 times.
