Abstract : A field trial was conducted at farmers field of Sibganj upazila under Chapai Nawabganj district of Bangladesh during May 2011 to April 2012 to investigate effect of pruning and fungicidal spray to control die back of mango plants. In case of medium infected plants significantly the lowest incidence (11.67%) was recorded from T2 followed by T1 (18.33%), T3 (25.56%) and the highest incidence (94.44%) was recorded from control (T0) plant followed by T7 (81.11%). Incase of severity the highest severity (45.11%) was recorded from control (T0) plant followed by T7 (30.89%) and significantly the lowest severity (3.78%) as well as highest disease reduction (91.63%) was recorded from T2 followed by T1 (6.89% and 84.73%), T5 (9.67% and 78.57%) treatments. On the other hand significantly the lowest incidence (7.78%) was recorded from T2 followed by T1 (18.89%), T3 (29.44%) and the highest incidence (99.44%) was recorded from control (T0) plant followed by T7 (90.44%) in case of severe infected plants. Incase of severity the highest severity (95%) was recorded from control (T0) plant followed by T7 (80%) and significantly the lowest severity (6.11%) as well as highest disease reduction (93.57%) was recorded from T2 followed by T1 (15.00% and 84.21%), T3 (21.22% and 77.66%) treatments. Based on findings of the present investigation pruning of infected twig and spraying of Cabrio Top (Pyraclostobin 5%+Metiram 55% WG) or Bavistin DF (Carbendazim) may be applied to control the die back disease of mango trees.
