Conteúdo: 	Traditionally the weed management has been done considering the overall weed infestation in the whole field and then herbicides are sprayed according to a single weed control recommendation for the field. But weeds are not uniformly distributed and normally have clumped populations showing weed patches presenting high spatial variability. This nature of the weed populations can be mapped, and so it can help the decisions with weed management on agricultural systems. However, localization and mapping of the weed clusters are very difficult tasks in large areas, and require adequate methodology. Therefore, determination method of this weed spatial variability must be scientifically studied. This document aim to provide information about the concepts, tools and methods of weed mapping considering that weed mapping technology is an important tool to bear on decisions associated with crop production, and it is a priority for the implementation of this technology multiple sources of scientific knowledge in weed biology and management regarding to the spatial variability.
