Abstract:The adequacy of velvetbean (Mucuna deeringiana), swordbean (Canavalia ensiformis), hairy indigo (Indigofera hirsuta), castor (Ricinus communis), and sesame (Sesamum indicum) as hosts for the reniform nematode was compared in the greenhouse with that of 'Davis' soyabean (Glycine max), 'DP-50' cotton (Gossypium hirsutum), a tropical maize cultivar, 'Pioneer 3156' maize (Zea mays), and 'FFR 331' sorghum (Sorghum bicolor). Cotton and soyabean sustained large populations (>500 nematodes/100 cm³ soil or per root system) of the nematode in both root and soil samples. High numbers of the nematode were also found in soil with castor, but roots of this plant had very low numbers (<10 nematodes/root system). All other plant species were either non-hosts or very poor hosts for the nematode. In other experiments with 24 selected cotton cultivars and nine soyabean cultivars, all soyabean cultivars except 'Maxcy' and 'Stonewall' sustained significant populations of the reniform nematode in soil. All cotton cultivars except one ('Hartz H 1215') sustained significant soil and root populations of the nematode.
