MANAGEMENT OF WHITE MOLD DISEASE OF CABBAGE (BRASSICA OLERACEA VAR. CAPITATA) THROUGH DIFFERENT PLANT EXTRACTS AND CHEMICALS

Abstract

The cabbage (Brassica oleracea var. capitata) is an herbaceous annual or biennial vegetable in the family Brassicaceae grown for its edible head. The cabbage white mold is one of the destructive diseases prevalent worldwide. The present study reports the finding of four fungicides and botanicals for the management of the pathogen. The efficacy of four fungicides was evaluated against the pathogen Sclerotiorum sclerotiorum (Lib) de Bary on PDA medium through the poisoned food technique. The recorded data advocated that the percentage inhibition of the fungal growth increased as the concentration of the fungicides increased. According to the results, fungal mycelial growth inhibition ranged from 92.91% to 34.69% after 96 hours. Similarly, the efficacy of three plant extracts was examined under laboratory conditions at four concentration levels viz. S, S/25, S/50 and S/75 by poisoned food technique on PDA. The radial growth of the fungus was recorded after 48 hours, 72 hours, and 96 hours of incubation. The inhibition percentage was measured and the results revealed that the garlic extract among all the three tested plant extracts was the most effective to inhibit the mycelial growth (49.54, 58.67, and 73.90%) of S. sclerotiorum at S/50, S/25, and S respectively after seven days followed by neem leaf extract (32.77, 44.97 and 61.73%). Leaf extract of safeda gave the least inhibition percentage of fungal growth of S. sclerotiorum.
