A Practical Approach to Weed Mapping

Most producers use herbicides to manage weed infestations. Generally, herbicides are applied at a uniform rate to the entire field. However, a uniform application may not be appropriate for all areas of a field. As precision agriculture technologies have developed, site-specific management of most agricultural inputs, including herbicides, has become feasible. Differentiated application of herbicides is an effective way to minimize herbicide costs, maximize weed control and prevent unnecessary environmental waste. This circular provides basic guidance on sitespecific weed management.
