Documentos, 91).  aABSTRACT: Curent interest in site-specific weed control considering the weed spatial variability is increasing nowadays, when economical and environmental aspects are considered. This paper reviews the patch spraying methods for herbicides application systems regarding the economical and technical aspects. Using this new approach high herbicides savings are possible, maintaining the efficacy of chemical control using the site-specific herbicide applications, and consequently reducing the environmental impact of the broadcast application of herbicides.  achemical control  aHerbicides  aspraying  aweeds  aAgricultura de Precisão  aControle Químico  aDefensivo  aHerbicida  aPulverização  aAgricultural chemicals  aDefensico  aPlanta daninha  aPrecision farming1 aCHRISTOFFOLETI, P.
