Plant parasitic nematodes are of high relevance and are known to attack several parts of plants. They are distributed widely in Nigeria and occur in all the regions and ecological zones of the country viz: north-west, north-east, north-central, south-east, south-west and south-south. Several losses and damages have been implicated to the pathogenic and parasitic activities of nematodes within the country and this aroused the interest of researchers. Notwithstanding, the use of various plant parts have served as a means in the control of nematode in the country. In addition, botanicals have been used to control and reduce the rate of egg mass production, egg hatching, larval population and gall formation in plant roots and soils. The efficacy of this control method has also caused an increase in the yield of the various tested agricultural crops infected by nematode.
