Divergent abiotic spectral pathways unravel pathogen stress signals across species
Spectral screening can be used to monitor plant health. Here via airborne hyperspectral imaging of tree species, the authors show that spectral pathways associated with vascular pathogens can be distinguished from those linked to abiotic stress providing the potential for early detection of threatening diseases.
