There is an increased interest and requirement for alternative weed control options in arable rotations due to herbicide resistance reducing control, a lack of new herbicide options being available and farmers wanting to reduce pesticide inputs. Electrical weeding is an innovative approach to weed management in agriculture. An electrical current passed through a weed turns into heat energy within the plant, causing the cells in the roots and foliage to burst, causing death or suppressing growth. Control is non-selective, affecting all plants that come into contact with the electrodes. Shielded applicators are now being used for development of in-row machines, however these are not currently available in the UK. Development of electrical weed wipers and the use of AI and robotics could offer site-specific spot applications in the future. The technique offers potential to reduce herbicide usage and enhance wider environmental benefits.
