Seeding Date, Carbofuran, and Resistance to Root‐Lesion Nematode Affect Alfalfa Stand Establishment

The root-lesion nematode, Pratylenchus penetrans (Cobb) Filipjev & Schuurmans Stekhoven, can reduce the establishment and productivity of alfalfa (Medicago sativa L.) in the northeastern and northcentral USA and in eastern Canada. Our objectives were to evaluate the effects of fallow and delayed seeding date, carbofuran (2,3-dihydro-2,2-dimethyl-7-benzofuranyl methylcarbamate) treatment, and plant resistance on P. penetrans populations in alfalfa roots and on alfalfa stand establishment and plant growth (...)
