How to Handle and Apply Pesticides Safely

1
Read and follow all label instructions. Many pest control
products have brochures or instruction pamphlets enclosed or
attached to their container. Here are a few examples of the
product instructions:
Mix 1 oz. of product per 1 gallon (3.8 L) of water. This is a
mix ratio. Using stronger concentrations does not make the
product
more effective, but can increase its toxicity.
Do not use in windy conditions. Windy conditions may cause the
product to drift into unprotected areas, or into a waterway
where contamination and unintentional aquatic life kill is
possible.
Do not mix with other products. Mixing pesticides, or any
chemical, may produce unexpected and dangerous results.

Read the warning label. The warning label contains specific
information about the product. Some obvious information may
include the following.
Its toxicity level.
"CAUTION" means that it is mildly toxic. Lethal dose is an ounce
or more.
"WARNING" means that it is moderately toxic. Lethal dose is
between a teaspoon and tablespoon,
"DANGER" means that it is highly toxic. Lethal dose is trace
amounts.
Avoid fumes, use in well ventilated area. Liquid pesticides may
produce poisonous fumes when the container is opened, or
while the product is being mixed and applied.
Avoid contact with skin. Many chemical products may be absorbed
through skin.
Avoid sparks or open flame. Pesticides are often suspensions in
petroleum distillate solvents, which can be highly flammable.

Use only appropriate containers for measuring, mixing, and
applying pesticides.
Never use food preparation utensils for this purpose. Even if
you only intend to use a measuring cup for your pesticide, it
could
accidentally be picked up and taken into the kitchen later.
Mix your pesticide in the application equipment if possible, to
avoid handling it during use. Commonly, compressed air or pump
up garden sprayers are used for this purpose. In agriculture,
tractor mounted, PTO driven equipment is used to apply
pesticides
on crops and farm land.
-
4 Mix only the amount of the product you intend to use. This can
be accomplished by reading the information on the label
under "application rate", generally in terms of gallons per
acre, or 'gallons per 1000 square foot". Measure the area you
intend
to treat, and calculate the amount of material required to treat
it. Storing left over mixed pesticides is generally not a good
idea,
but if you must, label the container according to contents and
date mixed, and keep it tightly closed.

Wash all equipment after each use. Use copious amounts of water,
and do not allow run off from washing to go into
waterways. Keep the washing operation away from wells or other
drinking water supplies.
-
6 Use appropriate safety equipment. This is usually listed on
the warning and usage label for each specific product, and the
following are some common items.
Safety glasses. These keep chemicals or dust from getting in the
applicator's eyes.
Rubber gloves. Rubber, neoprene, or other chemical resistant
gloves protect your hands from chemicals which may be
absorbed through your skin.
Long sleeved shirts and long pants. Another barrier protection
for your skin. When the application process is complete, remove
clothing and rinse it thoroughly before laundering.
Rubber boots. Because leather or cloth boots can absorb and
accumulate chemicals, it is often suggested that the person
applying pesticides wear rubber boots.
-
7 Never smoke, drink, or eat while applying pesticides.
-
8 Keep people and animals out of areas treated with insecticides
and other chemicals for the period recommended on
the product label. If you are using a liquid spray, no one
should reenter the area until the product is completely dry.

9 Be extremely careful applying pesticides in buildings or
homes. Use only products specifically labelled for this
purpose,
and remove any loose items such as clothing, books, and toys
prior to applying.
-
10 Do not use pesticides after any expiration dates on the
package.Chemicals undergo changes over a period of time, and
pesticides may become unstable, more toxic, or ineffective after
the expiration date listed on the package.

Use pesticides only at the intervals recommended by the
manufacturer. If insects return before the reapplication date,
you
will need to find a different control method. Most pesticides
recommend treating (or retreating) a crop or area at specific
intervals, often coinciding in the development rate of insects
from egg or larval stage to adult. Overuse can create chemical
resistance in the target insect and toxic levels of chemical
buildup in the soil, plants, and environment the pesticide is used
on.

Apply pesticides in the early morning or late evening to avoid
excessive drift (wind is normally lower during these time
periods), and to prevent exposing beneficial insects like bees
and ladybugs to the effects of them.

13 Be aware that certain pesticides are systemically active,
meaning the chemical is absorbed by the plant tissues and
distributed throughout the plant. For use on edible crops,
carefully follow the label instructions in regard to the period
prior to
harvest that pesticides may be applied, since simply washing the
product will not remove the poison.

14 Alternate suitable pesticides to obtain the best results in
pest control. This will ultimately give better control of insects
and
decrease the frequency of application.
-
15 Always look for the most environmentally sound, and least
toxic pest control method. This contributes to safety by
decreasing the use of poisons altogether. Planting certain
flowers like marigolds, and herbs like garlic will naturally
decrease the
insect populations in your crop. Bacillus thuringiensis or "BT",
is a bacterium compound which attacks certain insects when
topically applied to plants, while being harmless to humans and
animals.
