An Expert System for Diagnosis of Disease and Insect Damage of Satsuma Mandarin

Abstract

As the first step of application of AI (Artificial Intelligence) to agriculture, an expert system was constructed. This system makes diagnoses of disease and insect damage of satsuma mandarin and also suggests control methods for better growth. The system was constructed on ‘NEC PC-9801’ personal computer, using ‘Sogen’ which is a Japanese expert shell. Knowledge on disease and insect damage was rearranged and expressed in production rules, composing knowledge base.
The expert system works well and makes correct diagnoses. In the future, such applications of AI would be more important in agriculture.
