近几年来,我省穗醋栗生产发展较快,而当前生产中一个突出的问题就是白粉病的为害,影响了穗醋栗的育苗和产量的提高。过去防治措施一般是采用石硫合剂、砷酸钙、波尔多液等药剂,防治效果并不理想。1982和1983年,我们采用广东红门农药厂生产的硫胶悬剂(含硫量45～50%),对酷栗白粉病进行了田间药效试验和大面积防治,收到了明显的效果。现将获得的资料总结如下:
In recent years, the production of currant in our province has been developing rapidly. However, one of the prominent problems in current production is the damage of powdery mildew, which affects the growth of currant and the yield of currant. The past prevention and treatment measures are generally used lime sulfur mixture, calcium arsenate, Bordeaux mixture and other agents, prevention and control is not ideal. In 1982 and 1983, we used sulfur pesticide suspension (45-50% of sulfur content) produced by Guangdong Hongmen Pesticide Factory to carry out field efficacy test and large-scale prevention and cure of Ku Li powdery mildew and received obvious effect. The information now available is summarized as follows:
