Abstract:

Fungistatic activity of actinomycetes strain D01 on Fusarium spp., Rhizoctonia solani, Colletotrichum coccodes and Alternaria solani was studied by confronting incubation on PDA plates, and assessing the fungi growth rates. An inhibition ratio of more than 70% to four potato fungal pathogens was gained by D01. Substrate mycelium of target pathogens suppressed with antagonistic actinomycetes had been deformed or lysed. Actinomycetes D01 showed persistent inhibition effects on the target pathogens in different degrees, especially on C. coccodes and R. solani.
