苹果大星病(轮斑病),多年来一直采用退菌特、多菌灵、波尔多液等农药防治,效果日趋下降。我们于1987年用山东省果树研究所提供的日本进口50%速克灵可湿性粉剂进行了试验,取得了良好的防治效果。 试验地点设在本市张店区中埠镇铁冶果园,选择发病较重的15年生元帅结果大树作试材, Apple star disease (Rotiflame), over the years has been using anti-bacteria special, carbendazim, Bordeaux mixture and other pesticide control, the effect is declining. We in 1987 with the Shandong Provincial Institute of Fruit provided 50% of Japan imported Ke Ling wettable powder was tested and achieved good control effect. The test site is located in Tiede Orchard, Zhongbu Town, Zhangdian District of the city. The 15-year-old Marshal results tree with heavier incidence was chosen as the test material.
