Pictured above are the Rinieri side-sweep subsurface cultivator (top left and right), the comparative effects of Roundup versus the Rinieri (bottom left) and the Wonder Weeder (bottom right). During the 2004 and beginning if the 2005 season the Rinieri was used a total of three times, but inadequately controlled weeds in the organic plots compared to the IFP plots. Grass, which is the predominant weed in this orchard, was quickly able to re-root after being cut by the Rinieri and was never effectively controlled. The Wonder Weeder features several gangs of lilliston cultivators that should provide more aggressive action against grass and other weeds, with fairly low impact on soil quality.
