“What most of us don’t realize is that potatoes are one of the most “
treated” crops out there. It all begins in early spring with a soil
fumigant, which kills nematodes and disease in the soil. Fields are doused
with a chemical toxic enough to kill all traces of microbial life. Next
comes a herbicide to “clean” the fields of all weeds. At planting time a
systemic insecticide is applied to the soil which will be absorbed by the
seedlings and kill any insects on their leaves. Later a second herbicide is
sprayed on the field for weed control.
“The pesticide and chemical fertilizers are added to the irrigation system
(10 weekly sprayings of chemical fertilizer). Later comes a spraying of
fungicide to control blight. On top of this the fields will be sprayed with
toxic chemicals by air for aphids at 14 day intervals. Wow, I just lost my
appetite for French fries! The only way around this is to either buy
organic, or buy from a very small producer who may be skipping some of these
steps, or grow your own.”
