TOXICITY OF FUNGICIDES ON FUSARIUM SOLANI CAUSING DRY ROT OF ELEPHANT FOOT YAM

Present study was designed to explore the effect of fungicides on Fusarium solani causing dry rot of elephant foot yam. Altogether ten isolates of F. solani. from different localities belonging to districts of Maharashtra and Karnataka states were examined for their sensitivity to benomyl. There was quite a large variation in Minimum Inhibitory Concentrations (MICs) of benomyl against Fusarium solani both in vitro as well as in vivo. MIC in vitro ranged from 25 to 100ppm while in vivo it ranged from 15 to 80ppm. The isolate Fs-9 from Bidoor was more sensitive (25 ppm) on agar medium. The isolate Fs-3 from Jawalethar was highly resistant (100 ppm) on agar medium. In in vivo experiments, MIC of sensitive isolate Fs-9 was 15 ppm and that of resistant isolate Fs-3 was 80 ppm.
