Abstract
A recent survey reported that 98% of corn (Zea mays L.) and 92% of soybean [Glycine ~ (L.) Merr.] hectareage in the state of Missouri was treated with herbicides (58). Several researchers have noted that herbicides applied at very early growth stages controlled weeds at lower use rates (13). This indicates that the cost of weed control can be reduced by reducing the number of herbicide applications and/or reducing application rates required to achieve acceptable weed control. The high cost of herbicides, the potential danger of groundwater pollution, safety concerns, required soil and water conservation plans of the 1985 farm bill, and other economic considerations will dictate crop rotations and management schemes that reduce pesticide inputs and maximize ground cover throughout the year.
