Use of Plant Water Extracts and Bio-Control Agents for Post-Harvest Management of Mango Anthracnose Caused by Colletotrichum Gloeosporioides

Mango anthracnose caused by Colletotrichum gloeosporioides Penz. with its perfect stage as Glomerella cingulata is one of the most important and serious disease in all the mango growing regions of India including Himachal Pradesh. It causes 40 to 50 per cent post-harvest losses that sometimes increased up to 100 per cent under wet or very humid conditions. Efficacy of plant water extract and bio-control agents was tested against development of anthracnose on mango fruit cv. Dashehari. Fruit dip in leaf water extract of Azadiracta indica (15%) and solution of Trichoderma harzianum (1.2x104cfu/ml) for five minutes was found most effective and controlled the disease upto 70 to 80 per cent.
