Abstract

The research and analysis of the obtained measurements of the spectral reflectivity in the optical range of healthy and diseased potato plants affected by the Y-virus and late blight in laboratory conditions for the development of remote methods for collecting information on the phytosanitary state of seed and ware potatoes were carried out. Differences in the spectral characteristics of the reflection of the electromagnetic radiation of healthy and diseased potato plants in the optical wavelength range of 300-1100 nm were revealed, allowing to identify the presence of viral damage to potato plants and the development of late blight.
