Abstract: Basal stem rot is one of the important diseases of arecanut accounting to severe yield loss in southern India. The disease in Karnataka is reported to be caused by G. lucidum. The disease if unattended, is becoming a major threat to arecanut production in Andhra Pradesh, Karnataka and Tamil Nadu states. Management of the disease is possible with continuous monitoring and implementing biocontrol based integrated management approaches. Among the six treatments tried, application of Tridemorph as root feeding at 2m1 per 100m1 water during January, April and September along with application of both Neem cake @ 2kg per palm and Trichoderma harzianum at 100g per palm performed better in controlling the disease. Both Neem cake and Trichoderma harzianum was applied during onset of monsoon. By applying the above treatment palms recovered by giving higher number of healthy leaves (9.45 per palm) and reduced drooped leaves (3.5 per palm). This was closely followed by pure chemical treatments of either Tridemorph or Hexaconazole as root feeding.
