摘要: The effects of 10 strains Fusarium solani on Meloidogyne javanica were tested in vitro and controlled conditions. Culture filtrates the varied with respect to parasitism eggs females M. nematicidal activity terms juvenile mortality. Mortality boiled culture was slightly lower than that caused by un-boiled filtrates, but substantial retained, pointing relative thermostability active principle(s) involved. Aqueous ethyl acetate extracts F. produced higher a hexane extract indicating compound(s) polar nature. Conidial suspensions Fs5, Fs9 Fs10 used as soil drench significantly reduced nematode populations root-knot disease severity, resulting enhanced growth tomato plants. There no significant difference among shoot fresh weight. Strain Fs5 frequently reisolated from surface sterilized roots. When evaluated field test, strain reproductive potential, promoting However, root length weights Fs5-treated
