Air-Propelled Abrasive Grit Management (PAGMan) is being developed for selective, postemergence, in-row weed control in corn, soybean, and other crops that are grown in widely-spaced rows. PAGMan allows organic growers to control small weeds in row crops without seriously affecting the crop. It lessens the dependence on soil cultivation for in-row weed control. Weeds between the crop rows can be managed by other methods, such as inter-row cultivation, flaming, or mowing.
