RootWave, the UK-based pioneer in electrical weed control, has raised $15 million to scale its solution for eliminating weeds – including herbicide-resistant varieties – using electricity.

RootWave manufactures tractor-mounted implements using its patented high-frequency electricity, achieving what it says is up to 99 percent kill rates in a single pass during independent field trials.

RootWave has commercial sales in the UK and has also secured international manufacturing and distribution agreements, including a partnership with mechanical weeding company, Garford Farm Machinery. The company is actively conducting trials with several other agrimachinery manufacturers to expand distribution across Europe, with plans to enter the U.S. market thereafter.

RootWave’s electrical weeding technology is suitable for a wide range of crops from tree, bush and vine crops, to row crops including vegetables, broad-acre, and cereals.

The round was led by Clay Capital, a specialist food and agriculture venture fund, with participation from Agri Investment Fund – the investment arm of the Belgian collective Boerenbond Group – as well as vineyard-focused Xinomavro Ventures, Naruhisa Nakagawa, founder and CIO of Caygan Capital, Jorge Heraud, former CEO and Co-founder of Blue River Technology (acquired by John Deere), and returning investors V-Bio Ventures, Rabo Ventures and PYMWYMIC. The round includes $3 million in debt facilities provided by Innovate UK as part of the UK’s Future Economy initiative.
