Abstract

The effect of plant extracts on the mycelial growth and conidial germination of Colletotrichum gloeosporioides causing anthracnose disease of mango fruits tested under in vitro conditions. Twenty six plant extracts belonging to 21 families were tested for the effect on mycelial growth and conidial germination of the pathogen. The plant extracts of Adenocalyma alleaceum and Bougainvillea spectabilis were most effective in inhibiting the mycelial growth completely upto tenth day. The conidial germination was recorded at different intervals upto 24 h. As observed in mycelial growth there was no conidial germination in Adenocalyma alleaceum and Bougainvillea spectabilis.
