All the printed information including the label on the
product, brochures, and flyers from the company or its agent about
a pesticide product is called labeling. The label printed on or
attached to a container of pesticide will tell how to use the
product correctly and what special safety measures need to be
taken. Specific parts of the label include the following:
|
|
Brand name:
Each company uses brand names to identify its products. The brand
name shows up plainly on the front panel of the label. |
|
Type of formulation:
The same pesticide may be available in more than one formulation. |
|
Ingredient statement:
Each pesticide label must list the names and amounts of the
active ingredients and the amount of inert ingredients in the
product. |
|
Common name and chemical name:
Pesticides have complex chemical names derived from their
chemical composition. Some have also been given a shorter name, or
common name, to make them easier to identify. Pesticides may be
sold under several brand names, but you may find the same common
name or chemical name on all of them. |
|
Net contents:
The net contents tells how much is in the container. This can be
expressed in gallons, pints, pounds, quarts, or other units of
measure. |
|
Name and address of manufacturer:
The law requires the maker or distributor of a product to print
the name and address of the company on the label. |
|
Registration number:
A registration number must be on every pesticide label. It shows
that the product has been approved by the E.P.A. for the uses
listed on the label. |
|
Establishment number:
The establishment number tells which factory made the chemical. |
|
Precautionary statements:
A section with a title similar to "Hazards to Humans and
Domestic Animals" will tell the ways in which the product may
be poisonous to man and animals. It will also describe any special
steps necessary to avoid poisoning, such as the kind of protective
equipment needed. If the product is highly toxic, this section
will inform physicians of the proper treatment for poisoning. |
|
Environmental hazards:
The label tells how to avoid damage to the environment. Some
examples are: "This product is highly toxic to bees exposed
to direct treatment or residues on crops." "Do not
contaminate water when cleaning equipment or when disposing of
wastes," and "Do not apply where runoff is likely to
occur." |
|
Physical and Chemical Hazards:
Lists specific fire, explosion, or chemical hazards that the
product may have. |
|
Signal words and symbols:
Some pesticides may be hazardous to people. You can tell how
toxic a product is by reading the Signal Word and Symbol on the
label. |

Highly toxic pesticides are generally not sold in the
lawn and garden trade. All products must bear the statement "Keep
Out of Reach of Children." In some pesticide literature, the
term LD50 is used to give an
indication of toxicity. LD50
stands for lethal dosage necessary to kill 50% of a test
population of animals. The LD50
values are measured from 0 up. The numbers after the 50 represent
the milligrams. of the substance per kilograms of body weight
necessary to kill 50% of the test population. The lower the LD50
value the more poisonous a pesticide is, for example an LD50
of 5 is more poisonous than an LD50
of 20 because only 5 milligrams per kilograms of body weight are
necessary to kill 50% of the test population. |

Statement of practical treatment:
If swallowing or inhaling the product or getting it in the eyes
or on the skin would be harmful, the label contains emergency
first aid measures and states types of exposure requiring medical
attention. The pesticide label is the most important information
you can take to the physician when someone has been poisoned.
Without the label, it is difficult for the physician to help. |
|
Directions for use:
These instructions will explain several important items. |
|
- The pests the product will control
- The crops, animals, or other item the product can be used
on safely
- How the product should be applied
- How much to use
- Where and when the material should be applied
- Application to harvest periods
|
|
When used on fruits or vegetables, there may be a
period of time that must pass from the time of application until
it is safe to pick and use the crop. Known as the application to
harvest period and expressed as "days to harvest," this
is the time required for the residue to drop to safe levels. It is
often listed as a number in parentheses following the crop name.
It is a mistake to assume that a residue can be washed off. |
|
Misuse statement:
This section will remind you that it is a violation of Federal
law to use a product in a manner inconsistent with its labeling. |
|
Storage and disposal directions:
Every pesticide should be stored and disposed of correctly. This
section will tell you how to store and dispose of the product. |
