Interpretive Summary:

Technical Abstract: Field research was conducted as Rosemount, MN from 1991 to 1994 to evaluate a prototypic bioeconomic weed management model. In 1991, both seedbank- and seedling-based models resulted in similar weed control and corn yields with less herbicide use than a standard treatment. There were no differences in net margin among the model-generated and standard treatments. The models also reduced herbicide use compared to a standard in 1992. The seedling-based model resulted in weed control, corn yield, and net margin similar to the standard treatment. However, treatments based on the seedbank model yielded less corn than a standard treatment and had lower net margins. Seedbank-based treatments resulted in corn yields and net margin similar to the standard treatment in 1993, however, herbicide use was not always reduced. Corn yield and net margin was less using the seedling-based model than a standard treatment.
