Field experiments permitted to perceive differences in the reflectance of electromagnetic radiation from potato plant cultivars Bekas and Mila as well as differences between the plants treated with fungicides providing the protection against Phytophthora infestans and the untreated plants. A differentiation of the values of vegetative indices between potato cultivars resulted from the unequal development rate of the cultivars and from their different susceptibility to Phytophthora infestans. The assessment of potato plants infection by the studied pathogen using spectral measurements agreed with the results of field inspection.}, type={Artykuły / Articles}, title={Application of spectral measurements to the assessment of potato plants infection by Phytophthora infestans, the causal agent of potato late blight}, URL={http://www.czasopisma.pan.pl/Content/118509/PDF-MASTER/pan_doi_blank.pdf}, keywords={Phytophthora infestans, vegetation index}, }
