In vitro evaluation of fungicides against Colletotrichum gloeosporioides Penz. and sacc. Causing anthracnose in pointed gourd

Abstract

Use of fungicide is a common practice to control the diseases, so, the present investigation was carried out with isolation of the organism responsible for anthracnose to suggest suitable control measure in respect to fungicides in controlling anthracnose of pointed gourd caused by Colletotrichum gloeosporioides Penz and Sacc. Under in vitro studies thirteen fungicides at three different concentrations were screened by poisoned food technique for evaluating their efficacy. Among them Carbendazim + mancozeb (Sixer 75% WP) and propiconazole (Tilt 25% EC) at 500 and 1000 ppm, and hexaconazole (Contaf 5% EC) at 1000 ppm completely inhibited growth of the fungus and proved to be highly toxic to the growth of the Colletotrichum gloeosporioides.
