Management of horsehair blight (Marasmius equicrinis Mull) of tea.
An experiment was conducted during 2003 to 2007 at Bilashcherra experimental farm of Bangladesh Tea Research Institute (BTRI), Moulvibazar, Bangladesh to find out the effective control methods of simple clean, clean+sanitation, clean and sanitation and followed by foliar application of Carbendazim @ 750 gm/ha and clean and sanitation and followed by soil drenching with Carbendazim @ 750 gm/ha to control Horsehair blight disease (Marasmius equicrinis) of tea. All treatments with fungicides and application of clean and sanitation as cultural practice, Clean and Sanitation and followed by foliar application of Carbendazim @ 750 gm/ha caused significant reduction in severity of Horsehair blight in terms of PDI and increase of yield of made tea as compared to control, where any fungicide or cultural operations was not applied. Tea yield was negatively and nearly correlated with severity of Horsehair blight disease. Foliar spray with Carbendazim @ 750 gm/ha after clean and sanitation directly or indirectly can minimize the Horsehair blight disease as well as increase the production followed by soil drenching with Carbendazim.
