| Abstract: | 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 dif... |
