Biological control of burrowing nematode (Radopholus similis) in banana.

摘要

Field trials were conducted for two consecutive years (November 2004-February 2006 and July 2006-August 2007) for developing an effective and economical management of burrowing nematode in banana, using neem cake, farm yard manure (FYM), Paecilomyces lilacinus, carbofuran and sunhemp intercropping. Intercropping with sunhemp effectively reduced the nematodes population followed by P. lilacinus at 10 g infected grains plant-1+FYM at 500 g plant-1 and P. lilacinus+neem cake at 250 g plant-1. The highest yield (27.26 t ha-1) was recorded in the sunhemp intercropping, followed by carbofuran at 40 g plant-1 (26.96 t ha-1) and P. lilacinus+neem cake (24.64 t ha-1). The treatments also improved fruit quality parameters and benefit-cost ratio.
