Biocontrol of Meloidogyne incognita in Lycopersicon esculentum with AM Fungi and Oil Cakes

Anuja Bharadwaj and Satyawati Sharma
Currently chemical pesticides are the major means to control nematode-induced diseases but they are neither economical nor ecofriendly. Alternative methods are being sought to reduce the amount of chemical pesticides required. Arbuscular mycorrhizal fungi have been reported to reduce the infestation of root-knot nematodes on vegetable crops. Amendment of soil with some oil cakes has been found effective. A study was conducted on exploitation of the combined effect of AM with three different oil cakes Azadirachta indica, Brassica campestris and Ricinus communis oil cakes in controlling the root knot nematode Meloidogyne incognita. Combined use of AMF and cakes resulted in reducing the galling and nematode multiplication thus improving the plant growth and yield. The best results pertaining to AM root infection, nematode reproduction and plant growth and yield were obtained with the combination of AMF and R. communis oil cake.
