Abstract:
The study was conducted to find out the effect of cell free extracts of isolates of Trichoderma viride and Metarhizium anisopliae and Fusarium verticillioides on mortality and inhibition of egg hatching of Meloidogyne incognita in vitro. Mortality of Meloidogyne incognita was directly proportional to the cell free extracts of all the tested fungi and the duration of exposure. Maximum mortality of larvae was observed in higher concentration of Trichoderma viride followed by Metarhizium anisopliae and Fusarium verticillioides. Likewise different dilution of culture filtrates significantly inhibited the hatching of M. incognita eggs. Larval emergence was inversely proportional to filtrate concentrations. Significantly lower hatching was observed with higher concentration of CFE.
