Abstract

Effect of root-dip treatments with 500 and 1000 ppm of aldicarb, carbofuran, DBCP, disulfoton, phorate and turbufos for 15 and 30 minutes was studied on the plant growth and development of Rotylenchulus reniformis on brinjal Cv. ‘Pusa purple long’. DBCP was phytotoxic, Aldicarb, carbofuran and turbufos accounted for 73.6, 868 and 88.0 per cent reduction of both soil and root-populations of reniform nematode six weeks after treatment. Phorate and disulfoton were least effective. For prophylactic treatment in brinjal against reniform nematode infestation, 30 minutes root-dip treatments before transplanting can be advocated in 500 to 1000 ppm of aldicarb or carbofuran or turbufos.
