Abstract

Fungitoxic effects of six fungicides, namely, Benomyl, Derosal, Ridomil, Cabrio Top, Vitavax and Prevent at four concentrations, 5, 10, 20 and 50 ppm were tested through poisoned food technique. There was a significant decrease in mycelial growth of the fungus with an increase in fungicidal concentration. The most effective fungicides in inhibiting the growth of the fungus, in descending order were Derosal, Benomyl and Vitavax as they caused 100, 95.81, 93.80 and 70.96% reduction in mycelial growth, respectively at 5 ppm concentration. Ridomil and Prevent were least effective as they reduced 42.30 and 39.02% mycelial growth respectively. The fungicides which proved to be most effective in vitro were tested in green house grown plants. These fungicides were compared on the basis of mean number of wilted plants at all dosage rates at 39th day of sowing. Derosal and Benomyl were the most effective in reducing number of wilted plants followed by Vitavax, while the Cabrio Top was the least effective. Derosal and Benomyl exhibited 100% reduction in disease incidence, while Vitavex and Cabrio Top exhibited 96.33 and 88.37% in disease incidence, respectively.
