Not all problems are visible to the naked eye – especially during the early

stages of a pest infestation, disease onset, or nutrient deficiency. Unlike RGB

or NDVI cameras, multispectral sensors capture both visible and invisible

spectral bands and can highlight signs of stress and disease earlier and more

accurately. From the different bands, specifically the red edge band, it is

possible to generate indices to see individual chlorophyll levels in the plants

and compare over time. Low chlorophyll content is often an early indicator

of plant stress that would not be apparent in manual scouting. With plant

health maps, growers can quickly identify stressed areas and perform targeted

scouting for a more accurate idea of what is going on in their field
