Symptoms of pepper disease: Pepper can increase appetite and is one of the essential condiments for the general public. Once the pepper has acquired an epidemic disease, dark green round lesions appear on the leaves, the edges are not obvious, and when it is wet, white moldy substances may appear on the leaves. The lesions spread rapidly, most of the leaves are soft rot, they are easy to fall off, and they become pale brown after drying. . Stems infected, dark brown strip lesions appear, the edge is not obvious, above the stripe leaves withered, lesions were brown soft rot, wet spots appeared on the white mold layer. The fruit was infected, and the lesions were water-stained dark green soft rot. The edges were not obvious. When wet, the diseased part expanded rapidly. The whole fruit was soft and rotted, and the fruit was densely white and moldy. After drying, it turned light brown and withered. The condition of the pepper blight is: Spicy (sweet) pepper blight is caused by flagellin subphylum, spicy (sweet) Phytophthora infestans. The germs are borne by oospore in the soil or in diseased bodies and spread by wind, rain, irrigation and other agricultural activities. After the onset of disease, new sporangia can be generated and zoospores can be formed for reinfection. The temperature range for germination is 10-37°C, and the optimum temperature is 20-30°C. When the relative humidity of the air reaches above 90%, the onset is rapid; heavy spasm, low-lying land, poor drainage, excessive use of nitrogen fertilizer, excessive density, and weakened plants all contribute to the occurrence and spread of the disease. Pepper disease prevention and control methods: We will earnestly implement the plant protection policy of “prevention-oriented, comprehensive prevention and control†and do a good job in comprehensive prevention and control measures such as agriculture, ecology, and chemistry. 1. Implement crop rotation, deep plowing and soil reform, combined with deep plowing, soil spraying “no deep plowing†conditioners, increased organic fertilizers, phosphorus and potash fertilizers, and micro-fertilizers, appropriate application of nitrogen fertilizers, improve soil structure, improve soil and water conservation, and promote The roots are well developed and the plants are robust. 2. Strictly sterilize the seeds and cultivate aseptic seedlings. Before and 7 days after the planting, two pesticide bactericides shall be carefully sprayed to ensure that the net seedlings enter the room to reduce the occurrence of diseases. 3. Before the planting, the fired soil and high-temperature chambers are used to eradicate indoor residual pathogens. After planting, closed-type management is strictly implemented to prevent foreign pathogens from invading and spreading diseases to each other. 4. Combine top dressing and control of other pests and diseases. 5. Add carbon dioxide gas fertilizer, do a good job of fertilizer and water management, regulate the relationship between plant vegetative growth and reproductive growth, promote plant growth and growth, increase nutrition, and enhance disease resistance. 6. Comprehensively cover the plastic film, strengthen ventilation, regulate the temperature of the greenhouse and the relative humidity of the air, maintain the temperature at 25-30°C during the daytime, maintain at 14-18°C at night, and control the relative humidity of the air below 70% to facilitate the normality of the tomatoes. The growth and development of the plant is not conducive to the development of the disease and the prevention and treatment of diseases. 7. Observe and observe that a small amount of diseased leaves are found. Immediately remove the pods and find the stems. Immediately spray with propofol against propofol and eradicate the pathogens. The common diseases are: pepper blight, cucumber blight, late blight, tomato late blight, potato late blight, tomato early blight, tomato late blight.
