First, the law of occurrence. Maize brown spot is a kind of fungal disease. Its pathogenic bacteria is genus Chrysosporium and belongs to the flagellin subphylum. The pathogenic bacteria lived in the soil or diseased body with dormant sporangia and spread to maize plants through wind and rain in the second year. When encountering suitable conditions, a large number of zoospore germinate and the zoospores swim in the water droplets on the surface of the leaves and form. The infestation of silk affects the tender tissue of corn. There are many rainy days in the middle and late stages of corn growth, especially in conditions of high humidity and high temperature, which is conducive to the occurrence of diseases; low-lying land, continuous cropping disease is heavy.
Second, prevention and control methods. (1) Agricultural control. The disease-resistant varieties were selected and serious crop rotations were implemented for more than 3 years; the corn was fertilized and watered during the growth period to promote the robust growth of the plants and enhance disease resistance; the disease was completely removed after corn was harvested and deep-frozen in time to reduce the source of overwintering bacteria. . (2) Chemical control. Before onset or early onset, use 20% Triadimefon EC 3000 times, 50% Carbendazim WP 500 to 800 times, 70% Thiophanate WP 800 to 1000 times, and 12.5% ​​pods Lee WP 1000 times solution or 25% enemy deoiling oil 1500 times spraying, spraying once every 7~10 days, spraying 2~3 times; if adding appropriate amount of foliar treasure, potassium dihydrogen phosphate, Foliar fertilizers such as urea are more effective. When spraying, it is important to spray the middle and lower leaves and leaf sheaths.
