Targeting Precision Agrichemical Applications to Increase Productivity
Spatial variability of weeds in a field was used as input information for a bio-economic weed control model to generate preemergence, pre- plus postemergence, and postemergence herbicide strategies at three field locations. Weed control effectiveness, crop production, and profitability were estimated and compared with a producer's blanket herbicide application at each site. The recommendations from the bio-economic model were less expensive than the producer's treatment and resulted in similar or better weed control, yield, and net return. Using site-specific herbicide application and placement would optimize economic returns and environmental safety, benefiting the producer and society.
