[ Method] With self-made cream, heal wound anti 10 times 45% lime sulfur as materials, the control effects against blueberry. twig blight by different lengths of pruning and painting different creams were studied. [ Result] The probability of infection was lower when the pruning wounds were farther way from the diseased branches. Pruning branches at 15 cm away from infected symptoms and painting wounds with self-made cream received the best effnrt. The control efficacy of painting self-made cream was 100% in the first year, and 85.71% in the following year. The control efficacy of painting heal wound was 55% in the first year, and 22.63% in the lnllowing year. The control efficacy of painting lime sulfur was 42.07% in the first year, and 30.56% in the following year. [ Conclusion] Pruning branches at 15 cm away from infected symptoms and painting wounds with self-made cream could reduce the secondaq infection of new, born branches.展开更多
