University of Arkansas plant pathologists George Templeton, Roy Smith (USDA), David TeBeest and graduate student Jim Daniels conducted research in the early 1970s that led to COLLEGO, the first biological herbicide for weed control in a field crop. Other UA scientists and students worked on the project that resulted in EPA registration of COLLEGO by Upjohn in 1982 for control of northern jointvetch in rice and soybeans. The work provided a model used worldwide to develop biological herbicides. Leadership in this area helped the U of A obtain grants from the USDA and others for construction of the Rosen Center for Alternative Pest Control.
This marker is located on Maple Street at the northeast entrance to the Rosen Center for Alternate Pest Control.
