Carrying out studies connected with application of plants protection products for chemical methods of plants protection against pests and diseases requires to use databases in order to collect the obtained results. Databases, and more precisely information stored in them, may be used not only in the process of conducting further trials, but they may also be helpful for users of the bases, for example with their scientific work. This article presents a database application, “Documents archive”, based on the relational database designed and implemented by using SZBD Microsoft Access 2010. The software allows recording results of research and experiments related to efficacy of plant protection products at the Research Institute of Horticulture in Skierniewice, and effective usage of results obtained earlier in the research process of this unit. Uncom-plicated, user-friendly and fully automated interface of the presented database application was implemented based on diverse forms, with the usage of macro and VBA language procedures. Possibility of cooperation with diverse software significantly increases the possibilities that are offered by database application “Documents archive” in finding and processing the stored data, which makes it a very useful tool (IT tool) for research connected with plant protection. In this way, based on the research and experiments results stored in the base, the database application allows a quick evaluation of the applied plants protection products, as well as selection of the most effective scenario of their usage for a specific crop or pest.
