For precision weed management decision rules are needed that take into account spatial and temporal variability of weed populations and weed-crop interactions. The following chapter describes different decision rules for online and offline site-specific weed management. Those decision rules use crop-weed competition models, dose-response functions, weed population models and cost functions to calculate the best intensity of weed control for each field section. It is shown that herbicide input and weed control costs can be significantly reduced when farmers use those models in combination with modern sensor and application technologies.
