Weed management in cassava

Cassava (Manihot esculenta) is grown in many countries, being of great importance as an energy source for food, generating jobs and income. Although this crop has been proved to have high yield potential in some studies, reaching values above 100 t ha-1 roots, its national productivity in Brazil is low, being largely attributed to inadequate weed management. The interference of weeds results in competition for essential resources, such as nutrients, water, and light. In addition, incorrectly performed control of weeds in cassava can complicate management and increase production costs. In this review, aspects related to weed management in the culture are described, detailing the main components of interference. The critical period of competition, in many situations, is also discussed. Finally, the main methods of control aimed at the use of integrated management as a sustainable way of controlling weeds in this crop are presented.
