Abstract

The experiment was conducted to find out the survival condition of Black Rot disease (Corticium theae) of tea. Samples and data were collected from experimental field, BTRI and the causing pathogen of Black Rot (Corticium theae) was detected. In dormant period after pruning, Corticium theae can be still found in plant debris and pruning litres as fruiting body which contains spores. These spores are often the dusty and colored part of a fungus that is easily moved in the wind or in water. These spores adhere to and germinate on the tea plant surface, produce germ tubes, followed by development of germ tube and sent an infection peg through the cuticle. Following penetration, these fungi initiates sub-cuticular intramural colonization and spreads rapidly throughout the tissue with both inter- and intracellular hyphae that kill cells and tissue as they advance.
