Technical Abstract: Illinois farmers planted 22,400 acres of snapbeans (Phaseolus vulgaris L.) for processing in 2002 (about 10% of the U.S. total). Sixty seven percent of the Illinois acreage was treated with herbicides. However, snapbeans in Illinois are produced in environmentally- sensitive areas requiring a cost-effective, method if herbicides are relied upon. Field studies were conducted over two growing seasons to investigate the potential of mustard green manures to control of weeds in 'Highstyle' snapbean at Champaign, IL, on a clay loam soil, and Havana, IL, on a sandy soil. While results differed somewhat between the Havana and Champaign locations, the general trend was mid-season weed control by brown mustard [Brassica juncea (L.) Czern. 'Southern Giant Curled'] and the 'Caliente 119 Blend' which is a proprietary mixture of B. juncea and white mustard (Sinapis alba L.). A germination study in the greenhouse using weeds common to snapbean plots in the state confirmed the results of the field experiment, and provided samples for measuring the relationship between glucosinolate content of mustard and weed control.
