 ABSTRACT

Capsicum (Capsicum annuum L.) being an important vegetable and high value crop cultivated in the protected condition, is being affected by several post-harvest fungal disease anthracnose caused by Colletotrichum capsici (Syd.) Butler and Bisby. Ten fungal, eight bacterial bio-agents and ten fungicides  were evaluated in vitro by using dual culture and poisoned food technique respectively for studying their effect on the inhibition of mycelial growth of C.capsici. Among these bio-agents T. harzianum-16-IIHR, T. harzianum-58-IIHR showed maximum inhibition and B. subtilis P-37 inhibited radial growth of pathogen significantly over the control. Among ten fungicides viz., Propiconazole (100 %), Difenconazole (97.92 %) and Tebuconazole (100 %) were found effective at 250ppm, 500ppm and 1000 ppm fallowed by Nativo (58.19 %). Ten botanicals were evaluated in vitro by using poisoned food technique, among these botanicals Simarouba leaf extract recorded maximum per cent inhibition of the fungus, was 32.16, 36.47, and 42.75 per cent at 10, 20 and 30 per cent respectively followed by Subabul, Pongamia, and Neem leaf extract.
