Abstract: Abstract: In order to improve the level of pest control and the efficiency of management, and reduce manpower and material resources, an integrated management system for rice diseases and insect pests of Yangtze River Farm is structured. Based on NET 2.0 development platform and SQL SERVER 2000 Database Management System, this system achieves the various functions of user needs by designing a reasonable framework. The research combines with the actual demands of rice pest control of Shanghai Yangtze River Farm. First, on the basis of data acquisition of rice diseases and pest,we could forecast and early warn before the incidence of pests and diseases, and make a diagnosis when diseases and pests are discovered. According to the diagnosis, prevention proposals and programs are provided and an integrated control platform for rice diseases and pests is constructed. Based on the B/S model construction, this system solves to the pest control problems in the rice production of Yangtze River Farm.
