The occurrence of various degrees of corn diseases in the past few years, especially the outbreak of corn gray spot disease in 2006-2007, caused serious losses in corn production. The onset characteristics of corn gray leaf spot: mainly after infesting the male corn, invading the leaves, sheaths, and leaves of the plants. The occurrence of gray spot disease is affected by the weather conditions, especially the humidity is the most critical, and the relative humidity is above 90%. A long period of time is conducive to the occurrence and development of diseases. In the area of ​​corn planting, the cultivation technology of corn intercropping soybeans is used in combination with other agronomic measures to improve the microclimate in the field, make it airy and transparent, reduce the air humidity among the corn groups, achieve the purpose of disease prevention, and further explore a set of pairs. Maize diseases have preventive measures and accumulate and provide scientific basis for large-scale corn planting.
