Soil application of test systemic nematicides, in two doses, resulted in reduced emergence of larvae from cysts of Heterodera zeae except for oxamyl wherein both the dosages stimulated it. Aldicarb and phenamiphos were most effective in suppressing larval emergence. Larval penetration in roots as well as cysts formed were least with phenamiphos application. About 45 per cent of the penetrated larvae developed into cysts in carbofuran treatment as against 62–68 per cent in aldicarb.
