In-vitro evaluation of fungicides at different concentrations against Fusarium wilt in muskmelon caused by Fusarium solani (Mart.) Sacc.

Abstract

The present investigation was undertaken to evaluate potential inhibitory effect of indigenous fungicides (Five systemic, five contact and five combination fungicide) against Fusarium solani (Mart.) Sacc., a causal organism of wilt disease in muskmelon crop. In-vitro screening of fifteen fungicides was carried out by poisoned food technique using potato dextrose agar each at 500, 1000, 1500, 2000, 2500 and 3000 ppm concentrations. Antifungal activity was measured in terms of per cent inhibition. The results showed that tebuconazole 25.9% WW maximum mean inhibition of 97.74 per cent followed by propiconazole 25% EC 97.40 per cent mean inhibition, while least per cent mean inhibition (28.70%) was observed in case of Copper hydroxide 53.8% DF as compared to control.
