Pitaya canker is a fungal disease caused by the new dark-colored columnar fungus. The disease mainly affects the stem and fruit of the dragon fruit. The young stem is easily contaminated. It forms a round white spot in the early stage and gradually turns into brown spots or Black ulcer spots. Pitaya ulcer disease is easy to produce under high temperature and high humidity conditions, especially after a typhoon. Once the dragon fruit ulcer disease occurs, the broad-spectrum fungicide + copper preparation such as methyl thiophanate/carbendazim/desen manganese zinc is sprayed during the period before the disease, although the radical effect cannot be achieved, but the dragon fruit canker disease can be restrained to some extent. Sharply increased. In orchards where the disease is slightly more serious, it is almost impossible to control with chemical agents. The diseased stems should be cut off in time and taken to the park for destruction or burial. Clean up the diseased stalks and avoid contaminating other dragon fruit. Pitaya canker disease is particularly prone to outbreak under high temperature and high humidity conditions, and chemical control needs to be based on prevention and prevention. Spring temperature and humidity will rise, and it is necessary to treat both soft rot and scab disease during prevention and treatment to avoid compound contamination. Chemical control agent recommended formula 1:30% pyraclostrobin 1500 times + procymidone 1000 times +3% carbendazim or streptomycin 1000 times spray can be safely applied at various times. Formulation 2: 50% benzene. C 2000 times +40% prochloraz 1500 times + Chunleimycin or neutrophin, which can not be applied in flowering and young fruit.
