In-vitro evaluation of chemical fungicides against Colletotrichum capsici (Syd.) Causing anthracnose disease of chilli

Anthracnose of chilli is one of most important disease causing great economic loss. Anthracnose may cause yield losses up to 50 per cent. There is varied range of chemical fungicides available in the market for controlling this pathogen, viz. Colletotrichum capsici, but the extent of inhibition varies with different fungicides. Five fungicides viz. Kasugamycin (Kasu B 3%SL), Pyraclostrobin + Metaram (Carbrio Top 60%WG), Azoxystrobin (Onestar 23%SC), Fusilazole (Cursor 40%EC) and Carbendazim (Dhanustin 50%WP) were assayed for their efficacy against Colletotrichum capsici by Poison food technique. These fungicides were prepared at two concentrations viz. 250 ppm and 500 ppm concentration, evaluated for their toxicity against Colletotrichum capsici under in vitro condition using poisoned food technique. Under in vitro condition, all the fungicides which were tested against the growth of the fungus Colletotrichum capsici proved to be effective. Carbrio Top 60% WG was found highly effective with mycelia growth inhibition (72.66%) followed by (Azoxystrobin) Onestar 23%SC, (Fusilazole) Cursor 40%EC, (Carbendazim) Dhanustin 50%WP and (Kasugamycin) Kasu B 3%SL at 250 ppm with inhibition percentage of 60.78%, 43.77%, 31.1% and 24.4% respectively. Similar trend were obtained at 500 ppm also, the mycelial inhibition percentages were 81.45%, 72.33%, 66.67%, 52.4% and 35.2% respectively.
