    Abstract/Description
    One of the most cosmopolitan pests responsible for considerable negative economic impacts on yam is the plant-parasitic nematodes. They are also capable of facilitating fungal, bacterial and viral infections of yams. In order to produce healthy yam seeds to meet local demand and tubers for export, there is a need to identify nematode-free areas in Nassarawa, one of the hubs of yam production in Nigeria. To this end, 30 major yam growing communities of the state were surveyed to identify nematode-free areas. Structured questionnaires were administered to three farmers in each of the 10 local government areas selected. Results showed that 97% of the study areas investigated was seriously infested with the three key genera of plant-parasitic nematodes namely Scutellonema, Pratylenchus and Meloidogyne. Incidence and severity of tuber deterioration in transit threatened acceptability of the tubers when it eventually reached England. Healthy yams would attract more income than damaged ones.
