EVALUATION OF CHILLI GERMPLASM FOR RESISTANCE TO COLLETOTRICHUM CAPSICI AND ITS MANAGEMENT

Abstract

The present investigation was done to find out a resistant source among chilli germplasm against anthracnose (Colletotrichum capsici) by two methods of inoculation viz; pin prick and spray method. All the available germplasm was screened out against C. capsici in micro plots. None of the cultivar/lines was found to be fully resistant against C. capsici while Talhar, Sanam, C-33, C-19 and C-72 were moderately resistant. Longi was found to be highly susceptible. In vitro studies were conducted to evaluate the efficacy of different fungicides (Dithane M-45, Alliet, Carbendazim, Acrobit and Antracol) against C. capsici at different concentrations after three time intervals. All fungicides exhibited differential effects in inhibiting the mycelial growth of C. capsici. Among these fungicides, Carbendazim was the most effective in inhibiting the mycelial growth after 4, 8 and 12 days followed by Acrobit, Dithan M-45 and Antracol. The least effective fungicide was Alliet. The results of this study will serve in finding the resistance source against C. capsici and to select the most effective means for the management of C. capsici.
