Weed control is a challenge for organic growers. Organic producers rely on crop rotation, cultural practices, and mechanical weed control to control weeds. Some organic producers have experimented with clipping weeds above the canopy of short stature crops such as lentil or flax. A project was initiated in 1999 to develop or modify equipment for weed clipping and to evaluate whether the practice improved crop yield and/or reduced weed seedling recruitment the following growing season. At Scott, a field experiment was conducted over two years where clipping at various stages of weed development was evaluated. The clipping was done above a lentil crop canopy with a gas-powered hedge trimmer. The Prairie Agriculture Machinery Institute at Humboldt modified the cutting component of a self-propelled swather and carried out field trials on four farmer’s fields.
