Descripción
Major weeds affecting bean crops and their control are examined. The following aspects are also included: (1) classification of weeds; (2) problems caused regarding production; (3) effect of competition; (4) agro-economic aspects and relationship with other cultural practices; (5) weed control methods; (6) weed control in associated cropping; (7) no-tillage cropping systems. A total of 18 narrowleaf and 50 broadleaf weeds were found; among these the most frequent were: Echinochloa colonum, Sorghum halepense, Avena sativa, Amaranthus hibridus, A. spinosus, Agropyron repens, Argemone mexicana, Bidens pilosa, Cenchrus equinatus, Galinsoga parviflora, Lolium temulentum, Polygonum convolvulus, and Setaria viridis. Weeds are also listed with the names of the pests or diseases of which they can be alternate hosts. Problems caused by competition, the effect of other cultural practices on production, economic advantages according to the type of control used are discussed. Application rates and the evaluation of results for different var. are given as well as the herbicides recommended for maize-bean and cassava-bean intercropping. (CIAT)
