摘要： Different technologies for variable rate applications are discussed. Although no complete decision support system has been developed for site specific application of pesticides, it is claimed that simple application maps can be used to explore the technology. Such maps can be based on available yield or canopy density maps, simple field observations and the manager's experience. The density of the crop is an important factor having impact on foliar concentration of active ingredients and the competition between crop and weeds. Examples of field application maps are given. Farmers have been Satisfied with solutions for site specific applications based on a commercial spray controller with some saving up to 13 percent of chemical inputs. A proper infrastructure serving precision farming is needed in order to facilitate data exchange between farmers, advisory services and other services.
