Effect of botanical extract on controlling damping off disease of cauliflower

Abstract

Abstract An experiment was conducted with five treatments in pot culture at Chitwan, in Completely Randomized Design (CRD) with six replications to study the efficacy of botanicals in controlling damping off disease of cauliflower. Analysis of variance for each variable showed significant differences among treatments. The aqueous extracts of Neem leaf, Garlic clove and Bauhinia leaf were prepared for application. The positive control, Captan showed the highest efficiency in controlling pre - and post-emergence damping off and it was followed by Neem and Garlic, whereas both Neem and Garlic were statistically at par. Captan showed the highest germination percentage of seedlings 95.6% and least by Control (49.83%). The highest incidence of damping off was recorded in Control (80.49%). Neem and Garlic showed satisfactory results in controlling damping off disease and Bauhinia was insignificant with negative control. This suggested that, Neem and Garlic can be used to manage this nursery problem and more research is needed to be done in this regard.
