ABSTRACT
Among various biotic factors, nematodes are one of the leading plant pests impacting vegetable production. Nematodes attack mainly on below-ground plant parts, that is, roots, bulbs, corms, rhizomes, and others, reducing water uptake and transport. The chemical nematicides are primarily used to manage parasitic plant nematodes (PPNs). However, it is necessary to reduce the use of these nematicides due to their toxic effects on human health and the environment. Researchers are searching for eco-friendly and biodegradable approaches to chemical nematicides to manage PPNs. The oilseed cakes (mustard, neem, castor, karanj, groundnut, mahua and sesame) are now used to enhance soil fertility and reduce the pests and diseases of plants. The different forms of oilseed cakes have been used against various PPNs and found effective in lowering nematode population density. Therefore, in this chapter, an attempt is made to compile the available data on the practices of managing nematodes using oilseed cakes.
