Evaluation of Some New Nematicides for the Management of Reniform Nematode (Rotylenchulus reniformis) on tomato (Solanum lycopersicum L.)

Abstract

Investigations were carried out to evaluate the efficacy of two nematicides viz., Nimitz®(Fluensulfone) and Velum Prime (Fluopyrum) for the management of Reniform nematode (R. reniformis) on tomato (var. Pusa Ruby) under net house condition. The plant growth parameters in tomato were found to be increased in the treatment with Nimitz® @2.5kg/ha followed by Carbofuran CG @3.0 kg a.i./ha, Velum Prime @1000 ml/ha, Nimitz® @2.00 kg/ha , and Velum Prime @750 ml/ha. The chemicals suppressed nematode reproduction as indicated by the lower nematode population and lower numbers of eggs on the roots as compared to control. The minimum populations of R. reniformis were recorded with the treatment Nimitz® @2.5kg/ha followed by Carbofuran CG @3.0 kg a.i./ha, Velum Prime @1000 ml/ha, Nimitz® @2.00 kg/ha , and Velum Prime @750 ml/ha.
