Abstract: Sugarcane is the main sugar crop in China, and the diseases and insect pests are the greatest threat to sugarcane production. In recent years, the occurrence of sugarcane diseases and insect pests has presented new characteristics. The main changes are: firstly, the common diseases and insect pests are frequent occurred constantly; secondly, the secondary diseases and insect pests are raised to the main diseases and insect pests; thirdly, the diseases and insect pests are mixed occurrence and infection; fourthly, sudden and dangerous diseases and insect pests outbreak frequently, causing a disaster. The causes of new characteristics are analyzed from the source of diseases and insect pests, distribution of sugarcane varieties, climatic conditions and cultivation management. The green control measures of sugarcane diseases and insect pests are provided in this paper. First, strictly enforce the quarantine procedures for the introduced and transferred sugarcane seedling, breed and popularize the disease-resistant and pest-resistant healthy seedling. Second, improve the monitoring and early warning system in sugarcane diseases and insect pests, enhance the safety and scientific use level of pesticides. Third, integrate the technical mode of green control and explore the optimization and promotion mechanism. Fourth, establish and improve the emergency control mechanism, vigorously promote for the large-scale diseases and insect pests prevention. Fifth, innovate the technology training mechanism, publicize and popularize the new technology of plant protection.
