Basal stem rot or Ganoderma wilt caused by Ganoderma spp. is the most destructive and lethal disease in coconut. Refinement of management practices is imperative for effective management of Ganoderma disease in endemic areas. Thus, in the present investigation five new fungicides and biocontrol agents were tested against G. lucidum under in vitro condition in order to select effective ones to test against basal stem rot disease under field condition. Subsequently, effective fungicide such as Hexaconazole 5EC and bioagent, Trichoderma harzianum were evaluated under field condition for three years from 2014 to 2017. Results revealed that root feeding with 1%Hexaconazole 5EC+ soil application of T. harzianum enriched neem cake @ 5kg/palm at four months interval and soil application of T. harzianum enriched neem cake @ 5kg/palm at three months interval were effective in reducing the disease index from 32.2 to 17.1 and 36 to 20% respectively during first year and recorded complete recovery of the infected palms during third year
