Non-pathogenic Fusarium isolates were isolated and five isolates were selected for their biocontrol activity against Fusarium wilt of chrysanthemum. Different methods of in vitro tests were conducted, under the dual plate method the isolate UASB NPF-III and UASB NPF-I inhibited the pathogen by % and % respectively at seventh day of incubation. The cell free culture filtrates of non pathogenic Fusarium isolates UASB NPF-III and UASB NPF-I were found effective in controlling the pathogen by % and % at seventh day of inoculation. Similarly, the methanol and ethyl extract of culture filtrate of UASB NPF-III also have some effects on the pathogen and the inhibition per cent was about % and % respectively. | Biocontrol potential of non-pathogenic Fusarium isolates against the Fusarium wilt of chrysanthemum
