Abstract: For the randomness, fuzziness and incompleteness in the of system dynamic information, a fuzzy logic diagnosis model to the crops diseases and insect pests is built using the logic reasoning method in mathematical theory, and an algorithm is given to the known symptoms. Simulation example SHOES, the fuzzy logic algorithm can effectively complete the diagnosis on insect pests with the lack of many factors, symptoms and complete information, which is intelligent, simple and practical.

Key words: fuzzy logic, incomplete certain information, intelligent decision
