摘　　要：[目的]锈腐病是人参主要病害之一,对人参产量和品质造成极大影响,目前仍没有很好的解决办法。对柱盘孢菌侵染引起的人参锈腐病进行农药防治研究,筛选出防治效果较好的新型农药。[方法]对农业生产中常用的13种新型低残留农药通过抑菌试验、盆栽试验、田间药剂防治试验进行筛选。[结果]筛选出抑菌率和防效都在40%左右的6种药剂:25%戊唑醇WP、25%丙环唑EC、40%菌核净WP、50%烯酰吗啉WP、30%氟菌唑WP和80%代森锰锌WP。[结论]试验对提高人参产量、满足市场需求和提升我国人参产业整体水平具有积极意义。Rust rot is one of the major disease of ginseng,affecting greatly on yield and quality of ginseng,but there is no good method to resolve this problem.The study on controlling ginseng rust rot induced by Cylindrocarpon destructans was conducted to screen out highly effective fungicides for controlling ginseng rust rot.[Methods] 13 kinds of new common less-persistent pesticides were screened by bacteriostasis experiments,pot culture experiments and field trials.[Results] Six pesticides whose therapeutic efficacy and antifungus rate are both more than 40% are triazoles 25% WP,propiconazole 25% EC,dimetachlone 40% WP,dimethomorph 50% WP,triflumizole 30% WP and mancozeb 80% WP.[Conclusions] The research was beneficial to increase ginseng output and was good for catering the demand of international and domestic markets,and helpful to promote the overall level of ginseng industry in China.
