Problems solved by technology

The traditional method of preventing and controlling corn leaf spot is similar to pepper blight, mainly using disease-resistant varieties and chemical pesticides. At present, the above two diseases have obvious resistance to pesticides, which increases the cost of pesticide control, reduces the control effect, and pollutes the environment and agricultural products.

Abstract

The invention relates to a method of controlling hot pepper epidemic disease and corn big spot by cultivating hot pepper and corn in heterogeneity, belonging to plant protection field. The technique project of this invention is: keeping the mode of current hot pepper sprout cultivation and hot pepper and corn field cultivation, the plant distance, line space and density between the hot pepper and corn is the same with normal cultivating method. Opening furrow with width being 2-5m and depth 15-30m in the same field, planting hot pepper with 5-10 lines on the furrow surface, planting corn with 1-2 lines on the two sides of the furrow, the line space between the hot pepper and corn is 10-30cm, the corn seeding time can be same with the hot pepper transplanting time or seeding corn 1-15 days earlier than the hot pepper transplanting time, the hot pepper and corn can be planted relatively or in displacement. The invention can control the hot pepper epidemic disease and corn big spot with a good effect, can reduce the using amount of chemical pesticide greatly, increase product yield per unit area, and possesses outstanding economical, social and ecological benefit and wide application prospect.

Description

technical field [0001] The invention relates to a method for controlling capsicum blight and maize blight, belonging to the field of plant protection. Background technique [0002] Capsicum is one of the main vegetable crops widely planted in my country. With the development of the processing industry of capsicum products, the reform of rural farming system and the adjustment of industrial structure, the cultivation area of ​​capsicum is expanding continuously. At present, the annual output of fresh and dried peppers in my country ranks first in the world. Pepper blight is a devastating disease in pepper production in my country and the world. Once the disease occurs in the field, large areas of pepper will die within a few days, with an area of ​​up to 30% to 50%, and severe disease areas as high as 80% to 100%. Since there are no capsicum varieties with stable resistance and excellent varieties, pesticide control is an important means of preventing and controlling diseases...
