BEANS, SNAP—General Weed Management Strategy

According to USDA standards and processor quality control, harvested beans must be free of nightshade berries, Canada thistle buds, pigweed stems, and mustard pods. Crop rotations, close row spacings, early season weed control, and cultivation (except in rocky or clod soils) are combined with herbicides to minimize weed competition and contamination of product.
