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
