Extract

The control of annual weeds in row-planted crops such as soybeans and corn may become a major production problem whenever weather conditions limit the scope and effectiveness of tillage operations. With corn, the use of 2,4–D has greatly minimized this problem, but with soybeans the utilization of herbicides has been limited. Adaptation of herbicides to soybean production depends not only on herbicide performance but also on economic aspects of the problem. Recent studies (6, 7) reported average bean yield reductions of approximately 10 percent from the competition of average annual weed infestations. This emphasizes the importance of effective weed control and indicates some economic limits to the choice of methods to be utilized in practical weed control for soybeans.
