Recently it was during the hot season of cowpeas. Many vegetable farmers felt very annoyed because their kidney beans were not rusted, but they were full of insect eyes and they could not sell at a good price. In this regard, Li Xinhe, a peasant technician in Dazhai Town, Yangling Demonstration Zone in Shaanxi Province, analyzed that in the cultivation and management of cowpea, three kinds of pests and diseases must be prevented and treated. Otherwise, the above-mentioned phenomenon will easily occur. Seedling rust prevention “High humidity is an important condition for the outbreak of cowpea rust,†Li Xinhe said. If there is a large temperature difference between day and night, and the leaves condense for a long time, it is easy to cause a cowpea rust pandemic. Second, too dense planting or insufficient fertilizer can easily lead to disease. Rust mainly damages the leaves and can harm the soybean meal in severe cases. Therefore, it is necessary to prevent them at the seedling stage so as to prevent further expansion of the pathogen. Triadimefon and Sego are good agents for preventing and treating rust. Adult light spot fly to prevent Blight spotted fly mainly resides in the leaves of the plant and survives by the leaf-eating meat. Therefore, the presence of the light fly has a great influence on the photosynthesis of the leaf, which further affects the development of the plant and the growth of the fruit. Without affecting the normal growth of cowpea, water more and increase the humidity of the microclimate in the field, creating an environment that is not conducive to the survival of Liriomyza. Pharmacy, Li Xinhe said that avermectin permeability and systemic absorption are good, usually in the high incidence of spotted fly 2 or 3 times can be controlled. Flowering pods should be well protected Soybean meal mainly damages the leaves before flowering, and then drills into flowers and young foraging. This causes the loss of buds and pods. The resulting feces will also cause rot of the pods and seriously affect the yield and quality of cowpea. In response to this situation, Li Xinhe said that prevention and control must be timely, when the larvae are found in the flowering period of cowpea, they should be immediately sprayed with a suitable concentration of azide salt. Finally, Li Xinhe also emphasized that all three diseases and insect pests must be used. Therefore, it is recommended that growers must adopt a responsible attitude toward consumers, use low-toxic, low-residue pesticides as much as possible, and try to avoid using pesticides before harvest.
