Abstract : The efficacy and persistence of 14 plant extracts and carbendazim as mango fruit dip treatments were compared in controlling mango fruit anthracnose (caused by Colletotrichum gloeosporioides [Glomerella cingulata]). Carbendazim (0.05%) was the most effective control treatment. Eucalyptus oil (2%) and castor oil (10%) solutions inhibited infection for >2 weeks when fruit were inoculated and were significantly better than the other plant extracts tested. Castor oil (5%), eucalyptus oil (1%), garlic bulb, Zingiber officinale, mango, turmeric and Lantana leaves also significantly controlled the disease. Persistence was max. with carbendazim (0.05%) even in the pulp, followed by castor oil (10%), garlic bulb and ardusi leaves. Carbendazim left residues in the pulp but plant extracts only persisted in the pericarp.
