Abstract:
Papaya is infected by more than 25 diseases worldwide. Among those diseases, Colletotrichum gloeosporioides causing the anthracnose disease is much important as considering the post harvest scenario of papaya. Various factors responsible for post harvest rot of papaya. Therefore this attempt is being taken to investigate the anthracnose disease and to control by using the fruit dip treatment of best resulting plant extracts and bio-agents. The affected part shows elongated dark brown to black lesions, ultimately rotted and eventually fell off. The comparative fungi toxic potential of best resulting three plant extracts and three bio-agents were used. This study revealed that among the bio-agents, Trichoderma harzianum exerts the minimum disease intensity at 10⁶ cfu/ml concentration while among the plant extracts Lantana camara at 10% concentration shows minimum disease intensity.
