Pepper powdery mildew is one of the fungal diseases in the growth process of pepper. It mainly damages the leaves, and old leaves and young leaves can be infected. At the beginning of the disease, round white molds grow on the front or back of the leaves, gradually expanding, and soon become one. At the later stage of disease, the entire leaf was covered with white powder and then turned grayish. Relatively speaking, the disease on the back of leaves was heavier. The powdery mildew produced on the back of the pepper is a white powder, not a layer of mildew, and it is covered with spots. In severe cases, the entire leaf turns yellow and off, which seriously affects the yield and quality of the pepper. Generally, the incidence of late-stage disease is more, and more exposed areas tend to be popular when the weather is dry in mid-August and late-September. The main prevention and control measures of the disease: 1, agricultural measures selected disease-resistant varieties. Choose a high-pitched, well ventilated, well-drained plant. The application of phosphorus and potassium fertilizers avoid excessive application of nitrogen fertilizer during the pepper growth period. 2. Chemical control: In the early stage of disease, chemical agents can be controlled in time. The agent can be used with 15% triadimefon 1500-2000 times fluid, or 20% triadimefon EC 2500 times, or 50% carbendazim WP 500 times, or 50% thiophanate WP 500 times, or 70% thiophanate-methyl wettable powder 800 times, or 40% polysulfide suspension 500 times, or 50% sulfur suspension 300 times, or 2% Wuyi Aqueous 200 times solution of water, 200 times of agricultural anti-120 water agent, or 20% of 30% Tefu WP, or 600 times of 47% of Garnett WP, or 60% anti-mildew Water-soluble powder 1000 times and so on.
