Preliminary Research On Consultation System For Diagnosing & Controlling Vegetable Pests In Zhejiang Province

Vegetable is indispensable food for daily life. As people's living standard is increasing and China was affiliated to the WTO (World Trade Organization), the safety and quality of the vegetables have become not only the most direct and basic demand of the vast consumers but also have already become an important index of the international competition.However, technical instructions about pest identification and techniques for integrated pest management could not be transferred to the farmers in time, which has resulted in the overuse of pesticides and the high pesticide residue in vegetable.With the popularization of computer technology, the information and knowledge related to vegetable pest management could be transferred by using computer system as a media. Based on the previous, knowledge and experience, a preliminary computer system, named CSDC (Consultation System for Diagnosing & Controlling for Vegetable Pests in Zhejiang province) , was developed.The computer system was designed based on the information from potential users, extension staff and farmer, interviewed.The source knowledge was achieved from literature , experts and field experiments. The image of pests and symptoms were mainly is mainly acquired by SONY F707, and edited using ACDSee 5.0, Photoshop 7.0 and HyperSnap -DX5.0 , then saved with the format of JPG The database management system-VFP6.0 was used to construct the systems, which consists of rule database, fact database and picture database etc.The Consultation System for Diagnosing & Controlling Vegetable Pests in Zhejiang Province consists of the following:Subsystem for diagnosis and decision-making: It is the main body of CSDC, including two parts for disease and insect pest diagnosis and decision-making, respectively. The main function is to help users diagnose disease and insect pest problem they met and give advice for control actions.Subsystem for inquiring information on: The subsystem included the basic information and images of main diseases and insect pests. The main function is to help users to inquire information related to morphology , symptoms, life history , ecology and management of main vegetable pests.Subsystem for Integrated Pest Management: It is mainly provided basic principle and knowledge of IPM and control strategies for main vegetable pests based on crops. The main function is to help users make decisions using IPM principle.Subsystem for pesticide application: It is mainly provided information on reasonable use of pesticides in vegetable crop system. The main function is to help users inquire knowledge and information related to pesticide application and select right pesticide.Subsystem for food safety: It is mainly provided knowledge and information related to food safety. The main function is to help users learn and inquire relevant of food safety.Subsystem for system maintenance: It could be used to update and expand in the system, and improve its function.Finally the potential application and further we the future and development of CSCD were discussed.
