In vitro evaluation of different fungicides in inhibiting the mycelia growth of Colletotrichum capsici causing Anthracnose of chili

Abstract

Five fungicides were evaluated In vitro namely: difenoconazole, cabrioTop, azoxystrobin, carbendazim, and chlorothalonil by using poisoned food technique against Colletotrichum capsici for studying their effect on the inhibition of mycelia growth at different concentration (100, 250, and 500 ppm). Among these fungicides maximum inhibition of mycelia growth was observed in difenoconazole at 500 ppm almost complete inhibition followed by cabrioTop with 91.83% growth inhibition over control at 500 ppm. The fungicide azoxystrobin at 500 ppm recorded 83.04% inhibition. It was followed by carbendazim at 500 ppm recorded 79.21% inhibition. The least inhibition was recorded in chlorothalonil at 500 ppm which was about 71.56%.
