Weeds are considered pests as they can compete with the crop for soil moisture and nutrients. Because they may rooted deeper than the desired crop, they usually fare better in drought conditions than the crop. Even small fruits and tree fruits compete with weeds and is the reason why producers use herbicides to control the weed populations.
The Penn State Weed Management site provides information for controlling most weed species as well as the products that have been most efficient for the control of most species. You will see research reports and how to control weeds in various crops.
Organic producers will also find information regarding the control of weeds and the effectiveness of some control tactics used during organic production. Continual tillage and hand weeding is the only sure method of weed control for organic production but options do exist.
