Effect of seed dressing alone and in combination with foliar spraying of nematicide for the control of root knot nematode, Meloidogyne incognita on green gram

A green house experiment was conducted during Kharif, 1991 at Department of Nematology, Assam Agricultural University. Jorhat, Assam to evaluate a management schedule of root-knot nematode, Meloidogyne incongita on green gram with seed dressing alone and in combination with foliar spraying with nematicides. Seed dressing with carbosulfan 25 STD @ 3 per cent (w/w) followed by either single or double spray with carbosulfan 25 EC or triazophos 40 EC @ 0.1 per cent were found to be most effective management schedule in reducing the infestation of root-knot nematode in terms of reducing the number of galls (61.23–63.59 per cent), egg masses (71.89–75.11 per cent) and final nematode population (63.43–67.10 per cent) and increased the plant growth characters and number of pods per plant (128.00 -156.00 per cent) in comparison to untreated control.
