Abstract:
Damping-off is the most serious disease of tobacco in nursery conditions caused by Pythium aphanidermatum. Looking at the significance of the disease and economic importance of the crop in Gujarat. The experiment was conducted during Kharif 2021 at the Bidi Tobacco Research station in Anand, Gujarat. Nine fungicides were evaluated in nursery conditions for their efficacy against P. aphanidermatum by spray drench method. Significantly the minimum number of damped-off seedlings was recorded in the treatment of metalaxyl M 4% + mancozeb 64% WP (30/m²) with the highest PDC (92.16%) as compared to all other treatments. The maximum transplantable seedling/m² was observed in the treatment of metalaxyl M 4% + mancozeb 64% WP (910 seedlings/m²) as compared to all other treatments.
