ORCHARD-ORIENTED DECISION SUPPORT SYSTEM FOR PEST CONTROL ON APPLE AND PEAR

Farmers control pests based upon routine chemical application in their orchards. This ordinary chemical spray scheme resulted in higher costs, lower efficiency and caused environment pollution. In order to improve the pest management level, a decision support system for pest control in orchard was established. This system included farming data of each orchard, data base of biological characters of pests, mid and short term forecast models for 12 kinds of common pests, data base of expert experience as well as chemical data base. Based on weekly weather forecast, the system can predict the occurrence of pests and produce the related treatment suggestions. These suggestions were sent to farmers in the forms of newsletter and advisory telephone calls. After more than one year of running, the service was universally welcome.
