Field application of bio-organics in the management of Meloidogyne incognita in Mentha arvensis
AbstractA field trial was undertaken to determine the efficacy of Trichoderma harzianum isolate U, Glomus aggregatum, oil seed cakes of neem (Azadirachta indica), and mustard (Brassica compestris) in the management of Meloidogyne incognita and their impact on yield of menthol mint (Mentha arvensis) cv. Kosi. Significant reductions in nematode populations and root-knot indices were noticed in plots receiving oil seed cakes and bioagents, whose effects were equal to that of carbofuran. Application of oil seed cakes and T. harzianum significantly enhanced crop yield.
