Interpretive Summary:

Technical Abstract: Emergence patterns of foxtail were evaluated for three tillage regimes with three spring wheat seeding dates. The treatments were established in continuous spring wheat at Crookston, MN and in a soybean-wheat rotation at Morris, MN. Foxtail emergence percentages were generally not influenced by tillage regime throughout most of the emergence period, but when differences occurred, emergence was lower with no-till or no-till and chisel plow than moldboard plow. Foxtail seedling densities were greater in no-till and chisel plow than moldboard plow at Morris. By the third year at Crookston, foxtail seedling density was inversely related to tillage intensity. Delaying wheat seeding generally reduced foxtail percent emergence through most of the emergence period while increasing rate of emergence. Foxtail seedling density was also reduced by delaying wheat seeding. Producers using no-till or chisel plow regimes can expect more dramatic changes in weed populations and potentially greater weed infestations than in conventional tillage systems. Delayed spring wheat seeding may be an option for management of foxtail through reduced seedling density and more uniform emergence.
