The epidemic is a devastating disease of chili peppers, especially with high temperature, high rainfall, and high humidity. It is the peak period of the epidemic of chili peppers. It is extremely important how to diagnose and control properly. First, symptom recognition 1. The damage to the rhizomes, stems and lateral branches of the plants resulted in dark brown streaks. The edges were not obvious. The branches and leaves above the streaks quickly wilted. The base of the stems often had brownish soft rot, and sometimes the diseased section had a white moldy layer. 2, dark green round spots on the leaves, the edge is not obvious, when the air is wet, the lesion quickly expanded, the disease can see white mold, part or most of the leaves soft rot, easy to fall off. 3. The fruit was damaged. The lesions were dark green water stains, soft rot, and the edges were not obvious. They quickly spread to the whole fruit. When wet, the diseased fruit was densely greenish-green moldy. Second, the incidence of the law The oospore of the pathogenic bacteria can survive for more than 3 years. It is mainly used for wintering the oospore in the soil and the sick and can spend the season without planting the host crop. Under suitable conditions of temperature and humidity, the oospore germination begins, resulting in zoospores that invade the roots of the pepper, the base of the stem, and the leaves. During the growth of peppers, diseased plants successively produce sporangia and zoospores, which mainly spread with irrigation water and rain, and then re-infect multiple times. Pathogens can also spread through wind and rain and agricultural operations, causing leaf, branch, and fruit disease. In the field, only a handful of plants initially developed, but a disease transmission center was also formed. It quickly spread to the surrounding areas and infect nearby plants. Third, prevention and control measures After the rain, the drug should be taken in sunny days and the ground should be sprayed on the ground and the base of the plant. When there are individual diseased plants in the field, it is advisable to use a combination of comprehensive spraying and individual diseased planting methods.
