This paper discussed the warnings of Liberobacter asiaticum and citrus psylid control index, the economic life span of orange forests was then predicted by building the diseases spreading models with different management styles. At last, the paper put forward the comprehensive prevention and control technology and the concept that Liber-obacter asiaticum was preventable and control able.展开更多

However, there also have been some problems existing in practical production, such as leaf yellowing and canker. The causes for leaf yellowing mainly include the physiologic type and the diseases and pests type. This paper analyzed the causes and put forwards corresponding countermeasures.展开更多
