Branch canker caused by Macrophoma theicola is a major stem disease of tea plants (Camellia spp.). In tea plantations, this disease causes crop loss and it is one of the major limiting factor for yield stagnation. In very few instances it causes considerable damage in new clearings (about 3 or 4 years old) and large number of bushes have been killed. | Bio efficacy of indigenous biological agents and selected fungicides against branch canker disease of Macrophoma theicola tea under field level
