Specialist spot sprayer choice in the UK continues to increase, with Opico introducing the German-built Rumex range into this fast expanding sector. Rumex, which takes name from the Latin for docks, was originally developed to detect the weed in grassland. Now, however, the ‘green on green’ artificial intelligence (AI) system can not only detect broadleaf weeds in grassland, but also in other high value crops, including onions, carrots, sugar beet and potatoes.
