ABSTRACT
Major economic losses in Agriculture worldwide are reported to be caused by plant diseases,
therefore diseases management in an accurate and timely manner is of great importance. This
study assessed the effectiveness of using a spectroradiometer in detecting coffee diseases
(cercospora, CLR). Healthy and diseased plants were used to compare effectiveness of
different indices using a spectroradiometer. Results from this study showed that original data
from a spectroradiometer does not show pronounced reflectance differences between the
healthy coffee plants and the diseased plants. Twenty two known vegetation indices were
used to evaluate the reflectance on healthy and diseased coffee plants (plants infected with
cercospora, CLR). These indices were evaluated using ANOVA in Genstat 14th Edition and
seventeen indices were found to be effective in detecting coffee diseases. The highest
significant difference of p
