Abstract: The background of green techniques for plant protection in Baoshan tobacco production was sketched in the article. The situation of tobacco diseases prevention and pests control was increasingly serious. Chemical and physical prevention greatly polluted the ecological system and reduced the tobacco leaf quality and safety. And on this basis, we constructed a green technique system for plant protection with biological control as the dominant means, agricultural control as the basis. In the same time, the current situation of tobacco plant protection in Baoshan was reviewed, the major problems were summarized, and the application of modern tobacco plant protection was also analyzed. It was believed that the application of green prevention and control techniques could achieve pesticide reduction, and had a positive influence on the harmonious development of the quality and quantity of tobacco.
