Tomato (Lycopersicon esculentum) is the second most important vegetable grown in Brazil. Weed control in tomato culture is one of the main components in crop production costs. However, weed management is indispensable to achieve both high yields and fruit quality. A detailed discussion is presented in this work concerning the adverse effects of weed interference in the crop, both grown from transplanted seedlings and field-sown tomato. Aspects related to the critical period of weed competition during the crop cycle for both growing conditions are also discussed. Finally, the major strategies used for weed management in tomato crops are also presented, such as preventive, cultural, mechanic, and chemical control measures, based on the literature currently available.
