Bean crops are characterized by their high consumption and production worldwide. It´s high nutritional content makes it vulnerable to certain diseases, such as vascular wilt caused by Fusarium oxysporum, which generates significant economic losses. One strategy used to prevent this, is the use of microorganisms as biocontrol agents, with the aim of decreasing the use of chemical agents, promoting plant growth and using an eco-friendly alternative. This is why, in the present study, the antagonistic ability of three actinobacteria isolated from rizosferic soil of legumes (Streptomyces sp. MCR 33, MCR 24 y T3A) was evaluated against an isolation of F. oxysporum responsible for vascular wilt in bean crops. According to the results obtained from the in vitro confrontation tests, it was determined that Streptomyces sp. MCR24 does not inhibit the pathogen through amensalism, maybe due to the culture media used for this test. On the other hand, in the greenhouse tests there weren´t significant differences between Streptomyces sp. MCR24, MCR33 y T3A over the control of the disease caused by F. oxysporum, this might be because of the powdery mildew in the leaves of the bean plants, which restricted the correct development of the plants, making it difficult to observe the reduction of the severity of the foliar wilt caused by F. oxysporum. Nevertheless, according to the results from the plant growth promoting activity, it was shown that Streptomyces sp. T3A promotes the growth and development of the bean plants
