摘　　要：为筛选出防治香草兰疫病的最佳药剂,采用田间小区试验方法,测定68%精甲霜.锰锌WDG(水份散粒剂)、50%烯酰吗啉WP(可湿性粉剂)、25%甲霜.霜霉威WP、69%烯酰吗啉.锰锌WP、36%霜脲锰锌WP和70%乙磷铝锰锌WP等6种不同使用浓度药剂对香草兰疫病的防治效果。结果表明:68%精甲霜.锰锌WDG 1 000倍液、50%烯酰吗啉WP 1000倍液及36%霜脲锰锌WP 1 000倍液对香草兰疫病大田防效较好,分别为86.6%、81.4%和79.8%。生产上可交替使用这3种药剂来防治香草兰疫病。The control effects of six chemicals 68% Metalaxyl-M mancozeb WDG, 50% dimethomorph WP, 25% metalaxyl propamocarb WP, 69% dimethomorph mancozeb WP, 36% cymoxanil mancozeb WP and 70% Aliette Mn .Zn WP on Phytophthora nicotianae in vanilla were tested using field experiment. The results showed that 68% Metalaxyl-M mancozeb WDG, 50% dimethomorph WP and 25% metalaxyl propamocarb WP had better control effect to vanilla Phytophthora nicotianae. Three of them could be applied alternately to control Phytophthora nicotianae in vanilla production.
