REMOTE-SENSING AND IMAGE-ANALYSIS IN PLANT PATHOLOGY

This paper reviews various applications of remote sensing and image an alysis in plant pathology. It describes technical methods and their po ssibilities, but also emphasizes the biological prerequisites and rest rictions of practical applications. The subject area comprises many no ndestructive and noninvasive methods to detect and assess plant diseas es and stress objectively and cost-effectively, even though to date we cannot identify the specific cause of the damage. As a supplement to conventional methods, these new methods have great potential to facili tate and increase accuracy and precision in plant pathoiogical researc h.
