Weed pullers take the backache out of hand-rogueing

摘要

Hand-rogueing is the established but tedious means of cleaning sugar beet crops of tall weeds that have survived inter-row cultivation or a herbicide programme.So it will come as a relief to family members, agri students, farm staff and anyone else press-ganged into doing the job that mechanical alternatives are finally here.Inventive engineers in Germany and the United States have come up with weeding devices that grasp the offending plants between powered rubber tyres, pulling them out of the ground.
