Black gram anthracnose caused by Colletotrichum lindemuthianum is the most devasting disease. Due to its severe infection during humid climatic conditions spraying of chemical fungicides is essential to control the disease. Frequent application of synthetic chemicals, leads to the detoriation of environment and development of resistance. To overcome these situations, a study was carried out to examine the effect of twelve plant extracts viz., Acalypha indica, Ocimum sanctum, Coleus amboinicus, Phyllanthus niruri, Tribulus terrestris, Allium sativum, Parthenium hysterophorus, Lawsonia inermis, Senna alexandrina, Azadirachta indica, Anisomeles malabarica, Zingiber officinale were tested against the blackgram anthracnose under in vitro condition through poison food technique at 5% and 10% concentration. Among the plant extracts tested, Anisomeles malabarica recorded lowest mycelial growth of 3.2 cm and 1.0 cm and highest mycelial inhibition of 64.4% and 88.8% followed by Allium sativum recorded the mycelial growth of 3.5 cm and 3.0 cm and mycelial inhibition of 61.1% and 66.6 % against control @ 5% and 10% concentration respectively.
