Eco Friendly Management of Anthracnose of Black Gram

Abstract— With an objective to find out the non-chemical alternative to manage the Colletotrichum lindemuthianum (L), infecting anthracnose disease in black gram [Vigna mungo (L.) Hepper] in vitro condition during the year 2021-23. Different antagonist bio-agents viz. Trichoderma viride, T. harzianum, Pseudomonas fluorescens and Bacillus subtilis were evaluated by dual culture technique as well as efficacy of different organic inputs and phytoextracts viz. panchagavya, jivamrutha, cow urine, vermiwash, neem leaf extract, ginger rhizome extract, garlic bulb extract, datura leaf extract were tested in vitro by using poisoned food technique against C. lindemuthianum. The result indicated that among the in vitro tested fungal and bacterial antagonist, T. viride showed maximum growth inhibition of 60.48 per cent which was followed by T. harzianum (50.19%). Among eight organic inputs and phytoextracts, the highest mean growth inhibition of 60.99 per cent was recorded with panchagavya which was followed by jivamrutha (57.17%) whereas in pot condition vermiwash at 10 per cent gave highest per cent disease control (57.20%) followed by garlic bulb extract at 10 per cent (51.19%).
