COMPARATIVE PERFORMANCE OF OIL SEED CAKES AND PESTICIDES IN THE MANAGEMENT OF ROOT KNOT DISEASE OF DAVANA

R. Pandey

Abstract


Greenhouse studies were carried out to determine the comparative performance of oil-seed cakes of neem (Azadirachta indica Juss.), mahua (Madhuca indica Gmel.), castor (Ricinus communis L.) and the pesticides aldicarb, carbofuran and bavistin against the root knot nematode, Meloidogyne incognita infecting davana (Artemisia pallens). Neem oil seed cakes performed best and significantly increased the growth/yield of the crop, followed by aldicarb, castor cake, carbofuran, bavistin and mahua cake. Treatment of the soil with the oil seed cakes and pesticides considerably decreased the population of root knot nematode in Davana. Mahua cake and bavistin gave poor results.
