摘　　要：为解决苹果枝干轮纹病有效防治药剂缺乏的问题,1998—1999年在富士苹果枝干轮纹病树上开展其病害的药剂配方、浓度、防治次数、时期筛选及病斑不同刮治程度试验,2000—2002年在富士苹果枝干轮纹病树上开展果实轮纹病防治试验,结果表明,5波美度石硫合剂∶硅石粉剂=100∶4或100∶6对苹果枝干轮纹病具有显著的增效作用;1年2次施药效果显著;第1次施药前应采取轻刮,以后防治直接用药;多菌灵与波尔多液交替、多菌灵与石硫合剂∶硅石粉剂交替使用采收期与贮藏期防治果实轮纹病效果均突出;套袋果实轮纹病防效达100%。In order to solve the suitable fungicides for control of apple fruit canker disease, experiment of screening fungicides and their application formula were conducted with Fuji apple cuhivar. Results showed that spraying the solution of 5° lime-sulphur mixture ＋ silica powder in ratio of 100 ： 4 or 100 ： 6 twice a year could get it well controlled. Before first spraying the bark should be scraped lightly. Alternative application of Carbendazim and Bordeaux mixture, Carbendazim and lime-sulphur mixture ＋ silica powder could effectively prevent fruit infected by Physalosporapiricola during picking time and in storage. Bagging could prevent the infection of Physalosporapiricola by 100%.
