SUMMARY
Wheat and barley occupy the most prominent position in terms of production and acreage in developing countries. Plant-parasitic nematodes are a well-recognized constraint to production of cereals in fields. Cereal cyst nematode, Heterodera spp., is known worldwide as parasites of wheat and grasses. Cereal cyst nematode can cause significant economic yield losses alone in combination with other biotic and abiotic factors. The damage caused by this nematode can be enormous when it occurs in a disease complex, particularly in areas subject to water stress. For managing this nematode, an experiment was conducted in earthen pots of 1 kg soil capacity under screen house condition during 2017-18. There were four treatments with three replications of each. Castor cake (10g/pot) was mixed in soil 10 days before sowing (DBS). Neem oil @ 10 ml/kg seed was used as seed treatment. Among all these treatments, minimum number of cysts was observed in neem oil @10 ml/kg seed treatment followed by castor cake @ 10 g/pot (10 DBS) and subsequently improved the plant
growth parameters of wheat.
Key words: Cereal cyst nematode, wheat, management, neem oil and castor cake
