Efficacy of Neem Seed Powder on Root Knot Nematodes (Meloidogyne spp.) Infecting Bambara Groundnut (Vigna subterranea)
Keywords:
Azadirachta indica, bambara groundnut, Meloidogyne spp. and root gallingAbstract
Notwithstanding its economic importance, the production of bambara groundnuts (Vigna subterranea) is threatened by root knot nematodes (Meloidogyne spp.). The withdrawal of synthetic nematicides, however, from local markets has increased the demand for alternative products with nematicidal or nematostatic effects. Neem seed powder was evaluated at different application rates (15, 20, 30 g) and a control at planting to determine its effect on Meloidogyne spp. and yield of Vigna subterranea cv ‘Tom’ during the cropping season of 2012 on Research fields of the University for Development Studies, Nyankpala, Ghana. Results from the trials indicated that neem seed powder at 30g reduced the population of the pest and increased pod yield by 20% compared to the control. Neem seed powder at 30g could therefore be employed as a viable botanical nematicide against root knot nematodes attacking bambara groundnut instead of synthetic chemicals.
