Management of Heterodera zeae on maize through pesticidal seed dressing

Aldicarb, aldoxycarb and carbofuran @ 0.75 and 1.5 per cent and fensulfothion @ 0.25 and 0.5 per cent, both under pot and field conditions, were evaluated as seed dressers against Heterodera zeae. Seedling emergence was not hampered by chemicals both under pot and field conditions except to some extent in field by aldicarb at 1.5 per cent. Larval emergence in soil increased by application of nematicides, but their penetration into maize roots was inhibited. Aldicarb and and fensulfothion, at both the doses, were effective in reducing population of H. zeae.
