Suitability of Small Grains as Hosts of Meloidogyne Species
AbstractSeven cultivars of wheat, five of oat, one of rye, and four of barley were tested as hosts for Meloidogyne incognita, M. javanica, or M. arenaria under greenhouse conditions where soil temperature ranged from 21 to 34 C. Reproduction rates of all nematode species were high on all cultivars, except M. javanica and M. arenaria on 'Brooks' and 'Florida 501' oat. Meloidogyne incognita and M. javanica produced more eggs on roots of 'Rutgers' tomato than on cultivars of wheat, oat, rye, or barley. Key words: Avena sativa, barley, Hordum vulgare, Meloidogyne arenaria, M. incognita, M. javanica, oat, root-knot nematode, rye, Secale cereale, Triticum aestivum, wheat.
