通过对贵州花江柚木褐斑病病菌的多次分离培养,根据症状特点和致病性测定、病原菌的形态特点与培养性状,结果表明,柚木褐斑病的病原菌为链格孢属(Alternaria sp.)真菌.5种供试药剂中,75%猛杀生、60%茄苯得对菌丝生长有很强的抑制作用,2 000倍时对病原菌的抑制效果均在80%以上.

An foxiness pathogen was separated from the Tectona spp. in Huajiang ,Guizhou. According to the symptom and pathogenicity test, morphology and cultural characters, the pathogen was identified to be Alternaria sp. 5 fungicides were tested in vitro for efficacy against the Alternaria sp.Test on mycelia growth showed that 75%Mengshasheng ,60%Qiebende 2 000 time were the most effective fungicides, with their inhibitive rates up to80%. The results revealed that the efficacy of different fungicides on Alternaria sp. is different in the laboratory.
