Öğe Mechanical weed control(Elsevier, 2018) Hussain, Mubshar; Farooq, S.; Merfield, C.; Jabran, K.Evolution of herbicide resistance in weeds has increased the importance and scope of mechanical weed control. In many parts of the world, the efficacy of mechanical weed control has been reevaluated. Tillage (used for soil preparation for planting), although among the oldest methods of weed control, is still the preferred method of weed control for many farmers. Similarly, subsequent weeding (weed removal through manual or mechanical means) after the crop emergence is also a successful tool for effective weed management. Wise use of mechanical weeding can provide effective weed control in vegetables, fruits, and field crops. The use/choice of mechanical weeding method depends upon technical and economic factors. Weeds evolving herbicide resistance ultimately required either tillage, weeding, or other non-chemical methods; nevertheless, tillage has been considered the most effective among all non-chemical weed control methods. Development of intelligent weeders or automatic weeding tools may revolutionize mechanical weed control through the selective use of weeders in crops. However, a great deal of research work and investment is needed to develop robotic weeders, which are capable of functioning without human intervention for automated weed control in the future. © 2018 Elsevier Inc.
