| 摘 要： | 山药炭疽病病株样品10份按照柯赫氏法则分离纯化,测定致病性,并接种到梨和柑桔上,结果表明:引起利川山药炭疽病的病原菌其无性态为胶孢炭疽菌(,Colletotrid umgloeosporiodes)。选用6种杀菌剂对其菌丝生长、孢子萌发和芽伸长作了室内毒力测定,结果表明敌力脱、炭特灵和多菌灵对山药炭疽菌菌丝生长抑制作用最强;多菌灵、炭特灵、异菌脲、速克灵对其分生孢子萌发有强烈的萌发抑制作用,敌力脱和甲基托布津能有效地抑制芽管的伸长。

| Abstract: | Ten samples of Chinese Yam infected by colletotrichum were collected,isolated and purified and the pathogenicity test were conducted in line with Koch's postulate.The result showed that the pathogen causing anthracnose of Chinese Yam was colletotrichum gloeosporioides.Six fungicides were available for the living activation screening of Chinese Yam.The propicona-zole tanteling and carbendazium were remarkable for inhibiting the hyphe growth of Chinese Yam.The carbendazium,tanteling,iprodione and procymidone played an importance role in inhibiting the germination of conidium of.The propiconazole and thiophanate-methyl were good for the stretch of the germ tube of its conidium. |
