Palmer amaranth, a weed that is known to be glyphosate-resistant, continuously threats crops across the midwestern United States. To combat palmer amaranth, farmers use dicamba to control the spread in the farm. However, dicamba shows devastating effects that could harm trees and nearby farms during windy conditions.
With this, researchers from the University of Nebraska look for a solution that would secure the safety of the crops and animals within the food chain from these threats. They developed a rotating horizontal cylinder/roller on a honey dipper that would control the application of pesticide to crops.
Furthermore, tractors and small robots could mount the rollers to treat the weeds after the networks detect the exact location of the weeds. Through this solution, it will minimize the impact of farm activities on the environment.
Moreover, it would reduce the use of chemicals and metabolites from the food chain. The elimination of the risks that wind drifts cause would minimize the exposure of crops to pesticides.
