With the objective of evaluating the use of image analysis in the detection of "citrus tristeza virus" on lemon trees (Citrus limon (L.) Burm.) and to calibrate a screening method for the disease, color aerial photographs of sectors with lemon orchards in the Mallarauco Valley; Chile, and samples of healthy plants and plants with virus symptoms were taken. Elisa tests for the virus and analysis of the spectral signatures of the sampled sites were performed. Simple visual inspection of the photographs was enough to discriminate between areas with healthy and sick plants. The reflectivity of the three bands- blue, green and red - was higher in sick plants than in healthy plants. Moreover, the discrimination between sectors of diseased plants ...
