Management of root-knot nematodes (Meloidogyne spp.) in ashwagandha (Withania somnifera Dunal.), using different organic amendments in pot conditions

A pot experiment was conducted to study the efficacy of different organic amendments in varying doses for management of root-knot nematodes, Meloidogyne spp. in Ashwagandha, (Withania somnifera Dunal.). Results indicated that neem cake, poultry manure and mustard cake application proved to be more effective in improving plant growth characters and thereby reducing root-knot disease and final nematode population. Among the doses tested, higher dose of 5 % (w/w) was more effective than lower doses.
