ABSTRACT
Globally, plant-parasitic nematodes (PPNs) threaten agriculture and horticulture ecosystems and have paid more attention in the recent past. The loss caused by the PPN is enormous, and the management of PPNs by various chemical nematicides often reported the development of nematode resistance and harm to non-target organisms. So, oilseed cakes can be used as an alternative for nematicides. The application of various oilseed cakes on PPN has significantly decreased the nematode population and improved crop growth. Castor (Ricinus communis L.) is cultivated in many parts of the world and plays a major role in industrial oil. The application of castor seed cakes produces various defense-related components, including volatile organic compounds, reducing nematode mobility, egg hatching, and soil nematode density. Also, a combination of castor seed cake and microbial control agents were found to have excellent control over PPNs. This chapter explains the chemical properties, mechanism of action, various formulations of castor oil cake and its recommended doses in the management of nematodes in different crops and their effective utilization for sustainable agriculture.
