Root and hypocotyl rot of bean (Phaseolus vulgaris) was suppressed significantly by preplant incorporation of the herbicide dinoseb at the rate of 6.7 kg/ha as indicated by disease severity reductions and yield increases. Other treatments using dinoseb at 10.1 kg/ha and at the lower rate in combination with trifluralin were also effective, but treatments with trifluralin alone were not as beneficial.
