【摘要】 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更多还原

【Abstract】 year indoor fungicide effection measurement leads to primarily set up the poisonal effection files of the prohibition of several antiseptics on the bacteria of apple ring spot. Several fungicide showed good effection.2-year field study of application technigueshowed that to use carbendazim,benlate in the pre-growth period, bordeanx mixted with carbendazim,benlat,flusilazole,added to phesethyl-al alternation used in the middle and end period,will have a good effect on the control of apple ring spot.And the effect of only using fungicide when the patient bacteria of apple tree begin to act and extend is also studied .更多还原
