Bean leaf beetles have continued to be a problem for organic tofu soybean producers throughout the Midwest because of the resulting seed staining, which can downgrade the quality of the soybeans at market. Beginning in 2000, we evaluated soybean varieties at the Neely-Kinyon Farm in Greenfield, Iowa, for yields and percentage staining under organic production methods.
