Author(s): Raju J, Nagarajappa Adivappar and Jayalakshmi K
Abstract: Protected cultivation of high value cash crops is gaining momentum in Karnataka and cultivation of capsicum has become the choice of farmers. Powdery mildew caused by Leveillula taurica, is one of the most serious disease of capsicum grown in naturally ventilated polyhouse is affecting the quantity and quality of fruits. An experiment was carried out to know the effect of different fungicides including recommended fungicides against powdery mildew disease of capsicum (F1 hybrid ‘Indra’) in polyhouse during 2015. Among the 10 treatments, propiconazole at 0.1% proved to be best for the management of powdery mildew with minimum per cent disease index (9.64%), which was superior over all other treatments with maximum fruit yield of 98.00 t/ha which is followed by 0.1% of myclobutanil (11.90 PDI), tridemefon (13.03 PDI) and hexaconazole (15.86 PDI) with fruit yield of 94.62, 92.33, and 92.15 t/ha. Maximum per cent disease index (76.33%) was recorded in untreated control with less fruit yield (45.83 t/ha).
