Problems solved by technology

However, due to host variation or environmental impact, the disease resistance of pepper varieties is easy to lose, and the continuous use of pesticides also leads to the emergence of drug resistance, and the effect of pesticide application decreases. At the same time, the residual pesticides threaten human health and pollute the soil.

Abstract

The invention belongs to the technical field of vegetable cultivation, and particularly relates to a comprehensive control method for pepper scab. The comprehensive control method for the pepper scabcomprises the following steps: (1) soil planting pretreatment; (2) seed treatment; (3) applying a base fertilizer for soil preparation; (4) applying the base fertilizer for soil preparation; and (5) spraying pesticide. According to the cultivation method, the plant height, the leaf area, the stem diameter, the net photosynthetic rate, the stomatal conductance and the transpiration rate of the peppers can be obviously improved by soaking seeds with a pesticide, applying a large amount of organic materials and covering the peppers with films before transplanting the peppers, and applying a pyrroloquinoline quinone solution at different periods of the growth of the peppers after transplanting, in combination with certain fertilization and agricultural management operations, so that the morbidity and the disease index of the pepper scab are effectively reduced, the plant characteristics of the peppers are improved, and growth and development of peppers are promoted.

Description

technical field [0001] The invention belongs to the technical field of vegetable cultivation, and in particular relates to a method for comprehensive prevention and treatment of pepper scab. Background technique [0002] Pepper scab is one of the most serious bacterial diseases in pepper production caused by Xanthomonas rape, which has a great impact on the yield and quality of pepper. Pathogenic bacteria can overwinter on seeds and diseased residues in soil, and can also survive on pepper plants cultivated in protected areas. After the pathogen comes into contact with the leaves, it invades through the stomata and wounds. The bacterial pus overflowing from the scab is spread by splashing water droplets or insects, transplanting and agricultural tools to cause the epidemic of the disease. Long-distance transmission is mainly caused by the transfer of infected seeds. High temperature and high humidity, poor drainage, lack of fertilizer or excessive nitrogen fertilizer, sev...
