Abstract
Seedling alfalfa roots (Medicago sativa L. ’Saranac’) were protected from infection by Pratylenchus penetrans (Cobb) when alfalfa seed was treated with aqueous oxamyl at concentrations exceeding 2000 ppm. No infection occurred after oxamyl treatment at 32 000 ppm. Neither germination nor nodulation of alfalfa was adversely affected by treatment with oxamyl.
