矮化苹果集约栽培园因种植品种特性、修剪方式、水肥条件的不同,矮化苹果树势易衰弱,枝干轮纹病发生情况比乔化苹果园更严重。针对此状况,采用刮破主干表面病瘤后涂刷不同药剂组合处理,进行了矮化苹果枝干轮纹病防治试验。结果表明,60%唑醚·代森联水分散粒剂、80%三乙磷酸铝水分散粒剂+30%戊唑·多菌灵悬浮剂与白乳胶混配后病斑治愈率均达到75%以上,病斑表面呈现爆皮现象,内部长出新鲜的绿色组织,刮治的病瘤处呈黑色,并且不再扩展。而单独涂抹药剂、单独涂抹白乳胶和不刮破病瘤涂药对枝干轮纹病均无理想防效。
Dwarf apple intensive cultivation garden due to the characteristics of planting varieties, pruning methods, different water and fertilizer conditions, dwarf apple trees prone to weakness, the occurrence of branch wheel ring disease more serious than the apple orchard. In response to this situation, the use of scraping the main surface of the tumor after brushing different combinations of agents to deal with the dwarfing Apple Branch rot disease prevention and control trials. The results showed that the cure rates of 60% oxazolone dexamethasone water dispersible granules, 80% aluminum triacetate aqueous dispersible granules and 30% pentazolium carbendazim suspending agent and white latex were 75 % Or more, the surface of the lesion showed blasting phenomenon, the internal growth of fresh green tissue, scraping the tumor at the black, and no longer expand. The separate application of drugs, separate application of white latex and do not scratch the application of drug on the rotten rickets branches no ideal control effect.
