Variable rate technology for herbicide application

Abstract

Variable rate technologyVariable rate technology (VRTVRT) is used for the application of various agricultural inputs in order to respond adequately to the within-field variability of environmental factors like soil properties, incidence of pests and crop parameters. The areas in plant production in which VRTs are used are highlighted. For the variable rate application of herbicidesherbicides commercial as well as research solutions are described. The use of VRT for herbicide treatment with regard to pre-emergence Herbicides pre-emergence application and post-emergence Herbicides post-emergence application applications and the requirements are described. The potential of further herbicides savings due to an additional variation of herbicidal ingredients in consideration of herbicide sensitivity of single weed species and groups of weed species, respectively is shown and evaluated.
