Seed treatment has been an essential step in agricultural production systems, especially on chemical treatment which, despite being widely used, has the potential to harm the environment and the rural workers. Because of that, biological treatment using microorganisms has been widely studied within seed technology. Thus, the aim of this study was to analyze, through a systematic review, the situation of research and scientific dissemination, as well as the approach and the main microorganisms that current studied for application in seed treatment. For this review, a systematic search was carried out on the Web of Science platform from 2010 to 2020, evaluating the scientific production per year and the most important scientific journals, the microorganisms and plants used in studies related to seed treatment, in addition to the effects of these microorganisms in the seeds or seedlings. Studies with biological treatment with microorganisms in seeds have increased in recent years, with a consistent increase in the number of papers published in 2019 and 2020, and the journals that most linked articles with this subject were “Biological control” and “Legume research”. The most used microorganism for seed treatment is Trichoderma sp., especially T. harzianum, which is widely used in several agricultural species, such as corn, beans and wheat, with the focus, primarily, on the pathogens from soil and seeds.
