The Value of Pesticides
Take a bite into an apple or another piece of Insecticides are used to kill insects.
fruit. Do you ever wonder if you are going to
find a worm? Are you sure that what you eat
won't have bugs in it?
When your neighbor put in a lawn, did you
wonder why more grass came up than weeds?
Have you ever bought vegetables in the
grocery store? Did you wonder why they were
so healthy looking and appetizing?
These are examples of the benefits of a very
common type of chemical pesticides. -
Pesticides are poisons used to kill pests. There
are many different types of pesticides.

* Nematicides are used to kill nematodes.



Fungicides are used to kill fungi (mold and
mildew).












* Rodenticides are used to kill rodents
(rats and mice).

Herbicides are used to kill weeds.












There are many other pesticides in addition
to those listed.

Man has benefited greatly from the use of
pesticides. Pesticides have helped to control
diseases which affect man, animals and crops.
Insecticides kill mosquitoes, fleas, and other
insects that carry diseases. This has helped
prevent the spread of disease.
















Pesticides have also been of great value in
agriculture. Pesticides have enabled farmers to
produce more and better food than they ever
could in the past.

2. Restricted use These are dangerous

handling and applying pesticides can buy these.
These pesticides may be harmful even when
used as the label states.
The EPA can also remove some pesticides
from use. This has happened to some that used

Problems with Pesticides
Pesticides are easy to get and to use. Their
effectiveness is easy to see. But many people
have forgotten that there are other ways to
manage pests. Pesticides have caused some
problems.

pests. It may kill what you are trying to protect.
Even someone who reads the label may not
follow the directions. Some people may decide
that if what the label says to use is good, twice ,_ ,
as much pesticide would be twice as good. P '
Applying more pesticide than the
recommended amount is wrong. It endangers
the applicator and the environment. The
misuse of pesticides can also lead to other
problems.

TOO MUCH

Contamination of the environment.
Pesticides can pollute streams, rivers, lakes, and
even the ocean where they can kill fish and
other aquatic life. Rain may wash pesticides
into the water from fields that have been
sprayed. Careless pesticide users may .
accidentally contaminate streams and lakes.
Pesticides in the water can be returned to land
when the water is used by man.

Pesticides applied to crops may contaminate
other nearby fields and crops if they are
applied on a windy day.

Some pesticides may be dangerous to
wildlife. Small animals in or near sprayed fields
may be poisoned. Flesh-eating birds, like
vultures or eagles, may eat small animals

The egg shells break before they hatch, and the
young birds inside die.

Conclusion
As you can see, using a pesticide requires
careful thought and preparation. Not only must
you know the pest, but you must select the
right pesticide. You must then use this pesticide
properly.
Remember, pesticides are only one tool of an
IPM program. They are necessary and
important, but often are not essential.
Sometimes, we can do without pesticides. Use
pesticides only when you must. When you do
use them, read their labels and use them safely.
