Research Progress on Remote Sensing Monitoring of Pests and Diseases in Cotton
Pests and diseases seriously threaten the yield and quality of cotton,hindering the develop-ment of cotton industry.The traditional manual field survey method can hardly meet the needs of large-scale monitoring and forecasting of pests and diseases.Remote sensing monitoring technology can obtain cotton phe-notypic information nondestructively,and decipher the occurrence degree and spatial distribution information of pests and diseases quickly and widely,which has developed into an important way to monitor cotton pests and diseases.In this paper,the research progress of near-earth,low-altitude and satellite remote sensing moni-toring of cotton pests and diseases was described,the problems faced by the existing development was summa-rized,and the future research direction and application foreground was prospected,hoping to provide guidance and suggestions for the research on remote sensing monitoring of cotton pests and diseases.
