Effect of Forage and Grain Pearl Millet on Pratylenchus penetrans and Potato Yields in Quebec.

摘要: Rotation crop experiments were conducted from 1998 to 2000 assess the impact of forage and grain pearl millet (Pennisetum glaucum) on Pratylenchus penetrans populations in three potato (Solanum tuberosum cv. Superior) fields Quebec. These crops compared oats and(or) barley. Forage had a suppressive effect P. after 1 year rotation. The following year, marketable yields negatively correlated with initial densities two experimental sites (r = -0.454, P 0.044; r -0.426, 0.017).
