Abstract
Leafrot disease of coconut is caused by a fungal complex. Among the fungi associated, Colletotrichum gloeosporioides and Exserohilum rostratum are the main pathogens. Leaf rot is a destructive disease and complete control of it could not be achieved by fungicidal applications. Efforts were made to isolate native bacteria from rhizosphere of coconut and to evaluate their in vitro antagonistic potential against leaf rot pathogens so that the potential antagonists could effectively be used in leaf rot disease management. Two fluorescent Pseudomonas spp. isolated from rhizosphere were found to be effective antagonists of the main pathogens of leaf rot.
