people to try electricity to kill unwanted vegetation were the United States-based railroads in the 1890s. Scientists working for the railroads discovered that their new technology, high-voltage electricity, killed weeds dead.
Today, 130 years later, scientists are still working to perfect and commercialize electric weed-killing technology.
Hybrid electric desiccation is one of the most promising systems, and one that has already been used on a dozen European commercial farms. This system does not use herbicides or tillage.
Hybrid electric electrocution uses a highly conductive liquid that’s sprayed on the weed just before the zapper comes along. The liquid is designed to increase the power and spread of the electric jolt. A 5,000-volt jolt ruptures the weeds’ cell walls so water cannot move within the plant. Hybrid electric desiccation is a joint project with partners Crop.Zone in Germany and Nufarm of Australia. The electrophysical weeder project is known as Nucrop.
According to an email from Crop.Zone chief executive officer Dirk Vandenhirtz, pre-treating plants with the conductive liquid called Volt.fuel will efficiently control weeds and reduce energy use compared to conventional weeding technologies or other electric weeding technologies.
