Abstract

Among the different botanical extracts and modified Panchagavya, a natural product tested in-vitro against Fusarium oxysporum an incitant of Chili wilt disease. However, testing was carried out at three different concentrations i.e., at 5%, 10% and 15% and Carbendazim used as check. Garlic extract was found to be the best in inhibiting the growth of the fungus. All the other treatments also showed slow growth rate of fungus as compared to untreated control at all the three concentrations under investigation. It was found that higher concentration had more effect against the radial growth of fungus. Among the three concentrations tested, lowest mean radial growth of fungus was recorded at 15% as 32.99mm followed by 10% as 35.01 mm and maximum radial growth was recorded in 5% as 42.72mm whereas in control it is 90.00mm at 168hrs of incubation period. Among the botanicals and natural product (MPG) treatments, maximum per cent radial growth inhibition was found in garlic (92.91) followed by Darrek, wild sage, nongmangkha, ginger and MPG with percentage growth inhibition of 76.97, 56.80, 56.24, 45.50 and 42.72 respectively over the untreated control.
