A field experiment was conducted to study the management of root-knot nematode (Meloidogyne graminicola) in transplanted rice at Central Research Farm, Gayeshpur, Bidhan Chandra Krishi Viswavidyalaya, Nadia. The results revealed that all the treatments were significantly superior over check with respect to nematode population, root knot index and yield. Soil solarization of the nursery bed with 25 μm polythene sheet for 15 days during the month of May-June followed by soil application of Carbofuran 3G @ 1kg a.i. ha−1 at the 45th day after transplanting were reported to be the best way to manage the root knot nematode in rice with minimum soil and root nematode population (354.34 per 200 cc of soil and 363.91 per 5 gram root), root knot index (1.63) and maximum yield (2.35) with peak incremental cost benefit ratio. Highest percent reduction of soil and root nematode population with 53.59% of yield increase was recorded from the treated plots. However, nursery soil treatment with carbofuran 3G @ 0.3 g a.i./m2 and soil application @ 1 kg a.i. ha−1 at 45 DAT can also effectively control the nematode in transplanted rice.
Soil solarization of the nursery bed followed by soil application of Carbofuran 3G @ 1kg a.i. ha−1 may be used for the root knot nematode management in rice Nematode population from soil and root may be minimized through soil solarisation of nursery bed
