Abstract: One of the main phytosanitary problems in major crops are phytonematodes, which are characterised as diffi cult tocontrol. In view of this, biocontrol, through the use of biological agents, has become a driving force in controlling these pathogens.The ai m of this study was to evaluate the compatibility of microorganisms, and detect the possibility of antagonistic effects,influence on growth, or synergistic action when microorganisms are jointly applied to crops. Microbiological analyses werecarried out to observe the interaction of the fungus Trichoderma asperellum with the bacteriaBacillus subtilis and Bacillus methylotrophicus.It was found that the interaction between the genera Bacillus and Trichoderma did not promote any increase in the fresh or dry weightof the roots or shoots of the soya plants; however, based on the results of the microbiological analysis of the fungi and bacteria,the interaction was found to be promising, particularly in the evaluation carried out on the seventh day. Considering the number ofviable spores, the interaction between B. subtilis + T. asperellum showed better results than B. methylotrophicus + T. asperellum. TheInteraction between the genera Bacillus and Trichoderma showed the potential for joint use in the biological control of the soya bean.
