We previously reported Pear Pest Forecasting Management System (PPFMS) for the Improvement of pass ratio of Korean exporting pears. It is consisted of regular field forecasting by pear farmers, meteorological data obtained by automatic weather station (AWS), an internet web page (http://pearpest.jnu.ac.kr/) as information collecting and providing ground, and information providing service. Currently, we are expanding this system to the area, Cheonan and Ansung, where pear orchards are organized into exportation-specific group. Further, the information obtained from field forecasting and AWS were up-loaded to under-constructing upgraded webpage (http://www.kpear.kr), with several pest/disease-related information. We hope this pest forecasting management system increases the pass ratio of Korean exporting pears throughout establishment of farmer-oriented forecasting, inspiring farmers’ effort for the prevention and forecasting of diseases and pests occurring at pear orchards.
