A small article in "New Scientist"
I thought it would be of interest.
...............
Stressed plants can no longer hide their pain.
Chlorophyll usually disguises the signs of stress in diseased or
weak plants. But NASA researches have developed a filter that
blocks out most of the yellow and green light in reflected sunlight
to render the chlorophyll invisible.
Farmers wearing goggles fitted with the brownish plastic lenses
will be able to spot suffering plants before they are beyond help.
