In the present study, pathogenecity test was
performed to determine the pathogenic potential of four
strains of F. oxysporum. The results depicted that all the
strains had the potency to induce wilt as all of the strains
caused more or less typical symptoms on plants. Among
these, F. oxysporum strain B induced maximum
characteristic symptoms of wilt and plants died within
few days of inoculation. These results were found in
agreement with the work conducted by Mahmood (2010)
who reported the same trend of disease development in
tomato by A. alternata.
