ABSTRACT
Wilt caused by Fusarium solani is one of the destructive diseases of Solanaceous plants and causes considerable loss in the yield and quality of the produce. An experiment was conducted to isolate and in vitro evaluation of different chemical fungicides at four different concentrations viz., 0.5%, 0.1% 0.15% and 0.2% against Fusarium solani. The study was carried out using poisoned food technique for chemical fungicides in Completely Randomized Design (CRD). Among all the chemical fungicide, Bavistin proved to be the most effective chemical fungicide recording 100% growth inhibition at all the tested concentrations and Mancozeb and SAAF (Carbendazim + Mancozeb) which also showed 100% inhibition in 0.15% and 0.2% concentration. Mancozeb at 0.05% concentration was least effective in reducing fungal growth (35%). This study indicated better performance of some chemical fungicides even at lower concentration. So, such effective fungicides could be used to minimize hazardous effect.
