黄麻链霉菌 NF0919菌株对草莓枯萎病的生防活性初探
A Primary Study on Biocontrol Activity of Streptomyces corchorusii Strain NF0919 to Strawberry Fusarium Wilt
摘要
Abstract
We determined the indoor toxicity of the fermentation broth of Streptomyces corchorusii strain NF0919 to the pathogen ( Fusarium oxysporum f.sp.fragariae) of strawberry fusarium wilt through adopting mycelial growth rate method, and carried out the indoor pot experiment for the control of strawberry fusarium wilt.The results indicated that the EC50 values of NF0919 fermenta-tion broth and Phenazine-1-carboxylic against the mycelial growth of Fusarium oxysporum f.sp.fragariae were 24.3752 and 0.4001μg/mL respectively.On the 30th day after root-pouring treatment with the 20-fold dilution of fermentation supematant of NF0919 or the 800-fold dilution of 1%Phenazine-1-carboxylic SC, their control effect on strawberry fusarium wilt reached 65%or 90%, respectively.关键词
