Abstract:	Plant leaf diseases can be very destructive and for many crops they lead to lower fruit quality and yield. To safe our harvests and income many preventive pesticides treatments are applied to manage diseases. Early detection could help to substantially reduce pesticide application to healthy crops allowing a site-specific treatment. Diseases in leaves can be detected and specified using hyperspectral images. Some approaches even allow the detection before eye-visible symptoms appear. These imagers are expensive, usually not very handy, and typically not constructed for field use. We analyzed series of images of Phytophthora infestans and Botrytis cinerea artificially inoculated tomato leaves within their first 48 hours of incubation. Images were taken with two different handheld, low cost Canon Power Shot cameras producing three band JPEGs (near-infra-red, green, blue, and red-edge, green, blue). At 24 hours past inoculation (hpi) first differences could be detected in single band reflectance between healthy (mock-inoculated) and pathogen-inoculated leaf disks. Significant differences could be found in reflectance range, mean and median values as well as in the index pigment specific simple ratio (PSSRb). Current findings will be presented.
