With the current scenario of agricultural competitiveness, the use of Information and Communication Technology (ICT) tools has become increasingly common in the rural community, making life easier for farmers. The information obtained through Agroinformatics (Information Technology applied to agribusiness), serves as a basis for both decision-making, planning, and application of the best techniques and production processes. In Brazil, companies such as EMPRAPA (The Brazilian Agricultural Research Corporation) work in the research and development of new technological tools, which seek to boost the agricultural production of small rural producers, reducing their costs and improving their results. But for this, it is necessary that the producers understand the concept of the importance in carrying out information collection in a correct way, because the information will be processed according to what is inserted in the systems. In this sense, this article aims to demonstrate through an explanatory research of qualitative nature and bibliographical character the importance of the use of ICT to support decision-making in the Brazilian rural sector. Also highlighting the benefits originated by the use of ICT in all stages of agricultural production and its accounting management, through examples of tools.
