My research program focuses on the dynamics and management of annual weeds in organic farming systems. Current research projects include evaluation and comparison of seed-, seedling-, and mulch-based management strategies in organic vegetables. We also continue to evaluate physical weed control, aiming to improve understanding of the sources of variability in cultivation-based seedling mortality. Our current research related to weed management in organic grains is focused on wide-row- and band-sowing with inter-row, -band hoeing for improved physical weed control.
