Abstract

The invention relates to a method for preventing and controlling virus diseases of brassicaceous vegetables. The method includes the following steps: 1, ecological management, wherein microbial fertilizer Difulai is applied so as to activate soil, improve soil fertility, enhance the absorption capacity of plant roots, increase roots, strengthen seedlings and build plants; 2, agricultural prevention and control; 3, biological control, wherein 4000-fold 200 g / l imidacloprid dissoluble liquid is sprayed; 4, biological prevention and control, wherein a 500-fold 0.5% lentinan water agent is sprayed before occurrence of the diseases; 5, physical prevention and control; 6, chemical prevention and control, wherein chemical spraying protection is begun at the initial stage of the occurrence of the diseases, and 1000-fold 20% moroxydine.cupric acetate wettable powder is sprayed. The virus diseases of the brassicaceous vegetables can be effectively prevented; meanwhile, by taking the measures of agricultural prevention and control, physical prevention and control and the like for achieving integrated prevention and control, the average incidence rate of the virus diseases of the brassicaceous vegetables is decreased, the yield is increased, the plant grade is remarkably improved, and good economic benefits are obtained.

Description

technical field [0001] The invention relates to a method for preventing and treating viral diseases of cruciferous vegetables, belonging to the technical field of plant protection. Background technique [0002] Cruciferous vegetable virus disease, also known as mosaic disease, occurs widely in various parts of our country. In addition to various cruciferous vegetables, other plants such as Solanaceae and Chenopodiaceae are also susceptible. Symptoms: After the plant gets sick, bright veins appear on young leaves first, and then mosaic symptoms appear. Severely diseased plants are dwarfed and deformed, with shrunken leaves. Mildly diseased plants are generally normal, but poor bolting and firmness. The symptoms of Chinese cabbage are similar to those of pakchoi, but the leaves of severely diseased plants are shrunken and large, hard and brittle, and produce many brown spots. There are also brown necrotic streaks on the dorsal veins of the leaves, and cracks often appear. S...
