经过两年室内药效测定 ,初步建立起部分杀菌剂对苹果轮纹烂果病菌丝抑制作用的毒力档案 ,选出防效较高的几种单剂 ,并通过两年田间用药技术研究 ,明确果实生长前期 ,喷洒多菌灵、苯菌灵 ,中后期波尔多液与多菌灵、苯菌灵、福星等加三乙膦酸铝交替使用 ,对防治苹果轮纹烂果病有良好防治效果。同时探讨了只在果实潜伏侵染病菌开始活化扩展期喷药 ,对防治苹果轮纹烂果病的可能性 After two years of indoor pharmacodynamics test, the virulence files of partial fungicides on mycelial growth inhibition of apple rotten fruit were preliminarily established, and several single agents with high prevention and cure effect were selected. Through two years of field application research , Clear fruit growth early, spraying carbendazim, benomyl, in the late Bordeaux mixture with carbendazim, benomyl, Fuxing, such as the addition of triethyl phosphonic acid alternate use, the prevention and treatment of apple rotten rot disease with good control effect. At the same time, it explored the possibility of spraying pesticides only on the lurking stage of activation and expansion of fruit latent infection and controlling the rotten apple fruit rot pattern
