| 摘 要： | 采用多菌灵、咪鲜胺、十三吗啉、戊唑酮、百菌清等5种药剂对杨树新造林地溃疡病的病原菌——杜仲生拟茎点霉菌进行室内药效测定，结果咪鲜胺锰盐和多菌灵对病菌菌丝都有较好的抑制效果，同一种药剂对病原菌的抑制作用随供试药剂配比度增大而增强。在野外田间防治试验中，采用退菌特、咪鲜胺、福美双、多菌灵等4种药剂进行防治试验，结果表明，咪鲜胺、福美双、多菌灵对杜仲生拟茎点霉菌均有较好的防效，其防治效果分别为94．1％，94．1％，88．2％，退菌特防治效果较差，为58．8％。

| Abstract: | Five fungicides(e.g.carbendazim,prochloraz,tridemorph,thiram,chlorothalonil) were evaluated by the effectiveness to Phomopsis eucommicola in the Lab.Our results indicated that Prochloraz and Carbendazim had higher inhibition ability to the hyphae of Phomopsis eucommicola.Higher concentre of fungicide led to stronger inhibition to the pathogen.Through field tests,prochloraz,thiram and carbendazim had better controlling effects(94.1%,94.1%,and 88.2%,respectively).The control effect of tuzet was poorer,only 58... |
