Population Densities of Nematodes Under Seven Tillage Regimes
Abstract
Numbers of plant-parasitic nematodes on corn growing under seven tillage regimes were monitored. Differences among treatments occurred for Helicotylenchus pseudorobustus, Pratylenchus spp., Xiphinema americanum, dorylaimids, and total numbers of nematodes. Except with members of the Tylenchinae, highest densities occurred in no-till ridge plots and lowest numbers occurred in spring- and fall-plowed pots. Key Words: corn, Helicotylenchus pseudorobustus, Pratylenchus spp., Xiphinema americanum.Downloads
