Abstract: Bean plants with growth types and plant architecture that facilitate cultural practices and high productivity, have been an important requirement for farmers. However, overcoming competition with weeds becomes a limiting factor. This research was conducted to determine the period prior to interference (PPI) on bean cultivars of different types plant growth with an arbitrary level of 2.5%, 5% and 10% productivity loss. The experimental treatments consisted of eight coexistence periods of the crop and weeds: 0-10, 0-20, 0-30, 0-40, 0-50, 0-60, 0-70, 0-harvest days after emergence and a control plot that was kept weed-free throughout the study period. The experimental design was a random block design with four replications. The periods prior to interference were 21, 30 and 35 days for the BRS Pontal bean cultivar and 0, 5 and 12 days for the IPR Juriti cultivar, with the arbitrary levels of reduction of productivity of 2,5%, 5% and 10%, respectively, living with the infesting community composed predominantly of the species Digitaria sp., Portulaca oleraceae, and Eleusine indica. The architecture of the bean plant is of paramount importance in the choice of the farmer. However, 35 DAE of the bean plants, weed control must be don
