SEM-EDS and hyperspectral images of vine leaves treated with antifungal products Sánchez Alonso, Ramón Rad Moradillo, Juan Carlos Cambra Baseca, Carlos Castroviejo Fernández, Mª Pilar Barros García, Rocío Herrero Cosío, Álvaro Precision agriculture Hyperspectral imaging SEM EDS Mildew Copper Sulphur Vitis vinifera Scanning electron microscope, better known by its acronym as SEM, is a very useful technique for obtaining highresolution images of the surface of a sample. Hyperspectral imaging provides precise information for analysing vineyard vegetation that could help in improving pesticide application in precision viticulture technics. The present dataset is based on images of vineyard leaves, taken with both technics. The leaves of the cv. Tempranillo, proceeding from a vineyard located inside of the Cigales Denomination of Origin, in north-central Spain, were treated with two Cu-containing products: ZZ Cuprocol (70 % w/v copper oxychloride) and Cuprantol Duo (14 % w/w copper oxychloride, 14 % w/w copper hydroxide). In addition, a contact pesticide widely used in intensive and traditional viticulture based on Folpet, copper-free but containing sulphur and chlorine, has been tested in its commercial form, Vitipec Blue (Cymoxanil 6 % w/w, Folpet 37.5 % w/w, Ascenza, PT). Three dilutions were prepared, one of each compound, at the actual field application concentration of 1.33 g/L. The leaves were sampled and processed during the 2023 season. These leaves were taken from the central part of representative shoots of the vine canopy, with east and west exposures. After the application of the pesticide dilutions, images of the leaves were taken with a 300-channel hyperspectral camera (Pika L, Resonon) using a mechanical bench synchronized with the camera. Then the SEM analysis was carried after prepare the samples. Hence, such imagery is provided in the present dataset, based on the images taken from the leaves with both technics 2026-05-26T09:22:53Z 2026-05-26T09:22:53Z 2026-05-26T09:22:53Z 2025-10 info:eu-repo/semantics/article 2352-3409 https://hdl.handle.net/10259/11727 10.1016/j.dib.2025.111899 eng Data in Brief. 2025, V. 62, 111899 https://doi.org/10.1016/j.dib.2025.111899 http://creativecommons.org/licenses/by/4.0/ info:eu-repo/semantics/openAccess Atribución 4.0 Internacional Elsevier
