Mechanical Weed Control

The aim of this chapter is to highlight and focus on novel and promising developments in soil-engaging intra-row hoeing. Conventional weeding tools for intra-row treatments based on selectivity are limited in control efficacy. Four intra-row weeders based on computer-controlled soil-engaging tools are described. They all rely on input information about the crop plant locations for the tool control because they use non-selective principles. These systems use crop detection methods based on image analysis techniques, except for the tine rotor which uses geo-referenced seeds. Through these technological developments it is possible to control weeds with reduced or no use of herbicides, thereby meeting consumer and environmental demands.
