1. Symptoms: both seedling and adult plants are susceptible to diseases, but the incidence is relatively high in seedling stage. After the disease, the stem of the diseased plant will appear green water stains and become soft rot. When it's serious, the whole plant will collapse.
2. Prevention and treatment: spray or irrigate 800 times of 50% metalaxone wettable powder in time after the onset of the disease for treatment.
1. Symptoms: both seedlings and adult plants of Zanthoxylum quinquefolium may occur, but most of them occur at seedling stage. This disease will lead to stem rot and atrophy of the diseased plant, and even death of the plant.
2. Prevention and treatment: in the early stage of the disease, 72.2% pulicol 400 times solution or 15% oxamyl 450 times solution should be sprayed.
1. Symptoms: caused by infection of bacteria. It mainly damages the leaves of five color pepper. From June to August, the incidence is more than that after October. High temperature and humidity environment is easy to cause disease.
2. Control methods: field management should be strengthened at ordinary times to enhance the disease resistance of plants. Combined with pruning and reshaping, the dead branches and leaves were removed and burned intensively, and the mixture of 0.8-1 degree of Baume was sprayed once to reduce the overwintering pathogens. In the early stage of the disease, we should spray 50% dianthammonium 800 times solution in time. Once every 7 days, spray 2-3 times continuously to get better.
