A second hypothesis was that titer of grapevine leafroll-associated virus (GLRaV) could be correlated spatially to NDVI and other spectral indices. ...
To determine zonation, unmanned aerial vehicles (UAVs) with multispectral and thermal sensors were flown over six Cabernet Franc vineyard blocks in Ontario, Canada. ...

For such, reflectance of leaves in either condition collected in a "Merlot" vineyard during three growing seasons was measured using a spectroradiometer. ...
Among the viral diseases, the grapevine leafroll disease (GLD) is caused by some viruses known as grapevine leafroll-associated virus (GLRaV) of the Closteroviridae family, of which the GLRaV-3 is the ...

To date, six grapevine leafroll-associated viruses (GLRaVs) are known as causal agents of the disease, of which GLRaV-1 and -3 induce the strongest symptoms. ...
Ground-based hyperspectral imaging (400–2500 nm) was used in this study in order to identify white and red grapevine plants infected with GLRaV-1 or -3. ...

In this study, the potential of hyperspectral imaging (HSI) technology to assess the presence of powdery mildew in grapevine bunches was evaluated. ...
The obtained results suggested that HSI technology combined with chemometrics could be used for the detection of powdery mildew in black grapevine bunches. ...
