Although there are quite small areas sown with grain legumes in Romania, in recent years these crops have become more attractive to farmers also due to the fact that it leaves the soil enriched in nitrogen. Dried grain legumes crops have certain peculiar features that farmers must take into account to obtain profitable harvests. One of these features refers to the sensitivity of pea and bean crops to weed infestation, especially in the early stages of vegetation. In this context, the aim of the present study was to evaluate the efficacy and selectivity of the herbicides applied in pre and post-emergence on weed control in peas and beans. To this end, three experimental fields were conducted in Ilfov, Calarasi and Bucharest during spring and summer of 2020. Assessments were made at 14, 28 and 42 days after treatments application and they aimed at the effectiveness in controlling the mono and dicotyledonous weeds and crop safety. The results obtained have shown that the effectiveness of herbicides applied in peas and beans crops depends on weed species, their density on square meter, pedoclimatic and agrophytotechnical indicators.
