Evaluation of different botanicals, bioagents and fungicide against Colletotrichum gloeosporioides under in vitro condition

Abstract

Anthracnose a post-harvest disease is important in konkan region because losses also reported in Alphanso. Hence by management aspect evaluation of different botanicals Garlic clove (Allium satium) at concentration 20% found to be significantly superior over rest of the botanicals by inhibiting the mycelial growth at (54.12%) followed by Tulsi (Ocimum tenuiforum) (46.88%). In case of biogents maximum mycelial growth inhibition resulted with Trichoderma viride (92.38%), followed by T. harzianum (89.33%), B. subtilis (88.41%) and T. koningi (75.30%). Finally using fungicides Azoxystrobin 23% SC at concentration 0.1 and 0.05% was found to be most effective which inhibited per cent growth of the fungus at both concentration followed by Tebuconazole 50% + Trifloxystrobin 25% WG at 0.1 and 0.05 per cent concentration.
