Screening of 94 Strains of Soil Actinomycetes with Antifungal Activity

Antagonistic function of 94 strains antagonistic actinomycete on Sclerotinia sclerotiorum,Botrytis cinerea,and Fulvia fulva was studied.Antagonistic tests showed that 10 strains of which have better antagonistic action against three pathogens,and the inhibition rates were more than 60 %.The results of spore germination test showed that the inhibition rate of strains AXW4-1 and HVA29-2 were 86.9% and 78.8% to Botrytis cinerea respectively,and strains X-1-8 and GSA26-2 were 86.1% to germination of sclerotia.The test of leaves of oilseed rape showed that the filtrate of X-1-8 strain and GSA26-2 strain have more than 90% efficacy to Sclerotinia sclerotiorum.
