[目的]探讨油茶炭疽病复合病菌种类,筛选油茶炭疽病复合病菌的高效杀菌剂,为科学防治油茶炭疽病提供依据.[方法]从湖南、广西、广东、江苏,海南等地油茶成林采集炭疽病叶样本,采用组织分离法分离纯化致病菌,结合形态学和多基因联合系统发育分析进行种类鉴定;通过复合侵染试验研究致病菌之间的关系;采用菌丝生长速率法测定杀菌剂咪鲜胺、苯醚甲环唑、嘧菌酯、啶氧菌酯,氟吡菌酰胺和啶酰菌胺对油茶致病菌的室内毒力.[结果]1)从106个油茶炭疽病病斑中分离获得 186株致病菌,其中主要病原菌是炭疽属真菌 130株,拟盘多毛孢属真菌 18株,新拟盘多毛孢属真菌 28株,假拟盘多毛孢属真菌 4株,链格孢属真菌 6...

【Objective】This study aims to identify the compound pathogens causing anthracnose of Camellia oleifera and to screen effective fungicides for compound pathogens on C. oleifera, in order to provide targeted strategy for controlling C. oleifera anthracnose. 【Method】Leaf samples with anthracnose symptoms were collected from C. oleifera plantations in Hunan, Guangxi, Guangdong, Jiangsu and Hainan Provinces, China. Tissue separation method was used to isolate and purify the pathogenic fungi, and the morphological characteristics combined with an...
