resistant crops could
reduce the use of
weedkillers because they
can be used more
efficiently.
Bacteria and viruses can
infect plants and carry
genes to other plants and
animals.
Gene technology is very

Inserted genes can be
carried into wild plants by
pollination of crops with
closely related weeds.
Modified crops may be
more likely to give a sure
profit to the farmer.
Modified crop seed is
more expensive than
standard crop seed.
Farmers can grow some
crops in environments that
would normally be

Research into modified

businesses that are
interested in selling the
new varieties.
