In conventional cotton weed control programs the soil is tilled, a preplant incorporated (PPI) and/or preemergence (PRE) herbicide is applied, and from as many as three to four post-direct (PD) applications may be made. Each application increases the cost of production, often without achieving the desired level of broadleaf weed control. With the introduction of Roundup Ready cotton production systems, costs may be reduced by allowing less tillage and better control of some troublesome species not adequately controlled by conventional herbicides. Additional savings in production may be obtained by lowering machinery inputs and by allowing less expensive equipment to be used along with the possibility of reducing the number and amounts of herbicides applied to a field per year.
