Researchers from land grant universities across the Midwest are working on the concept of controlling weeds by zapping them with electricity.
Currently they’re testing the Annihilator 6R30 Weed Zapper mounted to a tractor. The work is being funded through the North Central Soybean Research Program and is in response to growers search for new weed control tools. In addition to electricity, researchers at Perdue, Southern Illinois, Iowa State, the University of Nebraska and Kansas State are exploring what is called harvest weed seed control.
In that method, weed seeds are managed or destroyed before they return to the soil seed bank to germinate the following season.
