Integrated management of Meloidogyne incognita on lentil cv. DPL-62 under field conditions

A field experiment was conducted during two consecutive years (2007-08 and 2008- 2009 cropping seasons) for the management of root-knot nematode (Meloidogyne incognita) on lentil cv. DPL-62 with biocontrol agent viz., Trichoderma harzianum alone @10 g/m2 (108 cfu/g talc), Vesicular Arbuscular Mycorhyzal fungus (VAM Fungus) viz., Glomus fasciculatum alone @5g/ m2 (150 spore count per g material) and in combination with a nematicide, carbosulfan 25 DS @1.5% (w/w). While as, carbosulfan 25 DS alone @3.0% (w/w) was applied as treated control. Pooled data of both the years revealed that among all the treatments, T. harzianum + carbosulfan was found highly effective in improving the percent nodulation/plant (34.4) and seed yield (37.3%) and reducing the final nematode population (86.8%) and root-knot index (82.9%) followed by G. fasciculatum + carbosulfan, G. fasciculatum + T. harzianum, carbosulfan alone, T. harzianum alone and G. fasciculatum alone, respectively.
