Electric power targets weeds with instant results
A new high voltage tool called the Weed Zapper is creating excitement among farmers and researchers across the country it was developed by researchers on Prince Edward Island. This innovative machine harnesses electricity to destroy weeds swiftly without the need for herbicides.
The Weed Zapper is designed like a mobile power station. A large generator attaches to a conventional tractor, while a heavy copper pipe, stretching 11 to 15 feet wide, mounts at the front.
As the tractor moves through fields, tall weeds brush against or even approach the copper pipe. The moment of contact sends a strong electric current through the plants. Within minutes the weeds wilt, and in just a few hours they turn black as the electricity finishes its work.
Agriculture and Agri-Food Canada biologist Nicolle MacDonald has started a two-year research project with AAFC weed scientist Dr. Andrew McKenzie-Gopsill to test the Weed Zapper at the Harrington Research Farm. Their goal is to target weeds that grow above the crop canopy in horticulture crops such as low-bush blueberries, potatoes, carrots, beets, turnips, and beans.
Electric weeding offers a sustainable alternative to chemical sprays, reducing the need for herbicides while controlling tough weeds. The researchers aim to learn how effective the Weed Zapper is in different field conditions and crop types.
Farmers and scientists see strong potential in this method of weed management. “It gives growers a safe way to harness electricity for fast weed control,” said MacDonald. If proven successful, the Weed Zapper could become a valuable tool for producers seeking an environmentally friendly and efficient solution to weed problems.
