Article Utility of Hyperspectral Data for Potato Late Blight Disease Detection
"The study was carried out to investigate the utility of hyperspectral reflectance data for potato late blight disease detection. The hyperspectral data was collected for potato crop at different level of disease infestation using hand-held spectroradiometer over the spectral range of 325–1075nm. The data was averaged into 10-nm wide wavebands, resulting in 75 narrowbands. The reflectance curve was partitioned into five regions, viz. 400–500nm, 520–590nm, 620–680nm, 770–860nm and 920–1050nm. The notable differences in healthy and diseased potato plants were noticed in 770–860nm and 920–1050nm range. Vegetation indices, namely NDVI, SR, SAVI and red edge were calculated using reflectance values. The differences between the vegetation indices for plants at different levels of disease infestation were found highly significant. The optimal hyperspectral wavebands to discriminate the healthy plants from disease infested plants were 540, 610, 620, 700, 710, 730, 780 and 1040nm whereas upto 25% infestation could be discriminated using reflectance at 710, 720 and 750nm.

A question.
Do you think that a set of hyperspectral or multispectral plant leaf data generated at a location in ex. Canada, can be used as a reference for stressed plants in India? Will climate difference a factor affect the results?
Different techniques can be used, The following articles can help you do your objective well.
