Description

technical field [0001] The application relates to the technical field of crop cultivation, in particular to a method for preventing and controlling lotus root diseases and insect pests. Background technique [0002] Lotus root is one of the main aquatic vegetables for the optimization and adjustment of agricultural structure and the development of ecological agriculture in recent years. Not only has the scale of cultivation in river beach depressions increased, but field planting and pond lotus development have also become the main economic sources for farmers to increase their income. Due to the improvement of lotus root unit area yield and output value benefits, it has led to its annual and successive years of repeated planting, resulting in serious accumulation of soil pathogens, causing the occurrence of lotus root diseases to spread, causing certain losses to lotus root production. In response to this situation, we discussed the hazard characteristics of the main diseas...
