摘  要:
[目的]探讨小檗碱复方对桃褐腐病的田间防治效果及安全性。[方法]根据杀菌剂作用机制选择β-微管蛋白抑制剂多菌灵、甾醇脱甲基化抑制剂腈苯唑和苯醌外部抑制剂(Qo Is)嘧菌酯作为阳性对照,研究了10%小檗碱可湿性粉剂不同稀释倍数(5 000、4 000、3 000、1 500、800倍)对桃褐腐病的防治效果及安全性。[结果]10%小檗碱可湿性粉剂4 000倍稀释液防治效果与对照药剂无显著差异,防治效果达70%以上;10%小檗碱可湿性粉剂剂量范围内对桃树安全。[结论]为小蘖碱在作物病害防治上的推广应用提供了参考。

摘  要:
[Objective] The field control effect and safety of berberine compounds on peach brown rot were evaluated. [Method] In view of antifungal mechanisms of fungicides,carbendazim,fenbuconazole,and azoxystrobin,which respectively represent β-tubulin inhibitor,sterol demethylation inhibitor,and benzoquinone external inhibitor,were used as positive control. 10% berberine wettable powder( diluted to5 000,4 000,3 000,1 500,800-fold) acted as the tested groups. [Result]10% berberine with 4 000-fold dilution was shown to be suitable for controlling peach brown rot fungus( Monilinia fructicola),and the control rates of berberine reached up to 70%. No significant differences existed between the tested and the positive control. Hence,10% berberine with 4 000-fold dilution was shown to be safe in peach production.[Conclusion]The study can provide reference for application of berberine in crop disease control.
