Nematode Response to Cool Season Annual Graminaceous Species and Cultivars
Abstract
The response of 29 rye, oat, triticale, and wheat cultivars to selected nematode species was determined in the greenhouse. Variability in nematode root galling and final nematode population densities in root and soil in response to cool season annual graminaceous crops occurred for spiral (Helicotylenchus dihystera), stubby root (Paratrichodorus minor), and root-knot (Meloidogyne incognita) nematodes. Although none of the graminaceous crops supported M. incognita at levels as high as the susceptible 'Davis' soybean control, sufficient variation existed among these to warrant field scale studies. Key words: Avena sativa, Helicotylenchus dihystera, Meloidogyne incognita, oat, Paratrichodorus minor, rye, Secale cerale, triticale, Triticum aestivum, wheat.Downloads
