Identification of Pathogenic Bacteria of Eggplant Soil Borne Diseases and Control Effect of Chaetomium globosum CEF-082
摘要
Abstract
In order to clarify the types of eggplant soil-borne diseases and the antagonistic effect of Chaetomium globosum CEF-082 on eggplant,the pathogen of eggplant wilt disease was isolated and purified by tissue separation method,and its pathogenicity was verified by soil inoculation.The pathogen of wilt disease was identified by combining morphology and molecular biology.The effects of C.globosum CEF-082 and fermentation broth on the hyphal growth,spore germination,and spore production of the pathogen were determined by confrontation culture method,drug containing medium method,and microscopic observation method.The control effect of C.globosum CEF-082 on eggplant soil borne diseases was clarified through pot experiments.The results showed that the pathogens causing eggplant wilting were Verticillium dahliae,Fusarium solani and Phomopsis vexans.The inhibitory effect of C.globosum CEF-082 and its fermentation broth had significant inhibitory effects on the mycelial growth and spore germination of V.dahliae and F.solani,while the inhibitory effect on the mycelial growth of P.vexans was moderate.The inhibitory rates of the 10%fermentation broth on spore germination of V.dahliae,F.solani,and P.vexans were 70.63%,69.93%and 67.69%,respectively.In the pot experiments,within 30 days after application,the control effect of C.globosum CEF-082 on Verticillium wilt,root rot,and Phomopsis blight in eggplant ranged from 46.95%to 55.68%,39.44%to 46.43%,and 71.78%to 95.19%,respectively.In conclusion,C.globosum CEF-082 has significant antagonistic and control effects on V.dahliae,F.solani,and P.vexans,providing a new approach for the green control of soil-borne diseases such as Verticillium wilt,root rot,and Phomopsis blight in eggplant.关键词
