Nowadays, many requirements must be fulfilled in relation to the application of agrochemicals in different productive stages of the export fruit in Chile. Agronomists in charge of productive orchards should consult different sources of information before proceeding to apply a certain product. This is based on technical guides and protocols that are also modified from time to time, which implies a complex task. Based on this problem, this work presents the development of an expert system that integrates updated information regarding the application and management of these products for the main fruit varieties exported from Chile. This using a relational database that allows different types of queries. This system works in real time and updates the database information dynamically. Periodically the system extracts information from web pages that have information on most of the commercial agrochemicals products of interest. It also allows the integration of other types of information provided by other users and experts to the system.
