Abstract: Plant diseases and pests is one of the three major natural disasters in China, its identification, monitoring and early warning is the information source of decision-making for prevention and control. The research results from Food and Agricultural Organization of United Nations show that natural loss rate of crop is more than 37% just because of crop diseases and pests. And China is a country with frequent and grave disasters of plant diseases and pests, without prevention and control measures against crop diseases and pests, about 150 billion kilograms of food crops, 6.8 billion kilograms of oil crops, 190 million kilograms of cotton, 100 billion kilograms of fruit and vegetables will be lost every year, and the economic loss will be more than 500 billion yuan. A low-cost nondestructive online real-time machine recognition system of plant diseases and pests will provide information for prevention and control of plant diseases and pests, set aside time for pest control system, minimize the economic loss, and improve quality and quantity of plants especially agricultural products. Research on machine recognition of plant diseases and pests is reviewed in this paper. Problems in recognition are summarized and analyzed, and solutions and future direction are presented, including recognition combined with prediction and pest control; fusion with remote sensing, global positioning system, geography information system, acoustics, machine vision, network technology; providing identification information about diseases and pests, plant growth and growth environment.
