Abstract:A web-based information management system of crop pest and disease (WIMSCPD) for the daily work of plant protection technicians was built using PHP+Apache+MySQL software in order to manage and use those history data of pests and diseases effectively. With an open mode, seven modules were built in this system including user management, dynamic tree-menu, online-design table, calendar warning, statistic and compare, and data displaying by chart. Therefore, users can customize tables of database for their demands. The system can manage many kinds of tables in the database conveniently by the dynamic tree-menu which has been connected with the module of online-design table. The database management functions include data query, sum, compare and display by chart, and so on. Users can built their own management system of crop pests and diseases on this platform through the internet web.
