A
large number of pesticides are used on corn, which
in North Carolina is grown throughoutthe state, both
for human consumption and animal feed. Corn is an extremely
chemical-intensive crop – conventionally-grown
corn requires many applications of insect-killers,
weed-killers, plant growth regulators and other types
of pesticides. If you live near a corn-growing area,
you may be exposed to these chemicals through drift
or runoff. Some of these chemicals may be applied to
corn fields from airplanes (called aerial application,
also known as crop dusting), which can increase the
chances of contaminating neighboring areas, such as
homes or organic farms. Chemicals that may be applied
aerially in North Carolina are followed by this symbol:
