Evaluation of Mycotoxic Potential of Some Higher Plants against Fusarium oxysporumF. Sp. L. causing Wilt in Linseed (Linum usitatisimum L.)

Linseed (Linum usitatisimumL.) is one of the major oilseed crops of India. The crop badly suffers by Fusarium oxysporum f. sp.L. pathogen causing wilting. Fifty plant species belonging to different families were collected and evaluated for their mycotoxic potential against the pathogen in in vitrocondition. All the 50 plant species showed the different level of toxicity. Among them leaf extract of Xanthium strumanium(Kanghi) and Tribulus terrestris(Gokhru) exhibited maximum toxicity and inhibited the mycelial growth of fungus upto 81.18% and 77.66%, respectively. Rest of the plant also showed variable per centage of inhibitionfrom 10.55 to 65.74% as compared to untreated check.
