Labels and Labeling

How to read supporting documents produced by the manufacturer

Labels and Labeling: Labels

The label is an EPA required document describing allowable use of a product.

  • To the manufacturer it is a license to sell
  • To governments (state & federal) it is a way to control distribution, sale, use, storage, transport, and disposal of the product
  • To the buyer it is the main source of information about how to use the product safely and legally
  • And, to tell the user about any safety measures needed for appropriate use

Labels and Labeling: Labels – Required Data

  • Name of product
  • Chemical and common name of the a.i
  • Ingredient statement including percent of content and type of formulation
  • Name and address of manufacturer
  • EPA registration and establishment numbers
  • Signal words and symbols
  • Pesticide precautionary statement
  • WPS requirements and precautions
  • Statement of practical treatment
  • Directions for use
  • Plus several other items

Label Information on the Web

Collateral pesticide infoon the web

Permissions in FIFRA (Federal Insecticide, Fungicide, and Rodenticide Act)

  • May use pesticide at a rate lower than listed on label
  • May use a pesticide on a target not listed on the label – as long as the site is listed
  • May apply the pesticide by a method not listed on the label as long as the method is not prohibited on the label

FIFRA Requirements

  • Site of application must be on the label for proposed use to be legal
    • This leads to some confusion
    • For most herbicides "site" is described as "Site-preparation", "Conifer release", etc
    • For insecticides "site" often means the target pest such as "Gypsy moth" or "Bark beetles on conifers."

"It is a violation of federal law to use this product in a manner inconsistent with its labeling."

Do Not memorize label information!

Look at the label at least four times

  • At the time you prescribe its use
  • When the shipment arrives onsite
  • At the tailgate safety session for crews
  • At the time of disposal

Example chemical?: Velpar L, Garlon 3A, Garlon 4

Labels and Labeling: The Velpar L Label

  • We’ll use the Velpar L (hexazinone) label for most of this discussion
  • Note that herbicide labels are among the easiest to read
  • (Monsanto’s and the companies which have bought repackaging rights to former Monsanto products are the exception)

Not from the
example label -
this “DANGER -
POISON” notice
is required when
appropriate (LD50
of 50 of or less).


Labels and Labeling: The Garlon 3A Label

  • We’ll use the Garlon 3A (triclopyr) label for most of this discussion
  • Note that herbicide labels are among the easiest to read
  • (Monsanto’s are the exception)

Labels and Labeling: The Garlon 4 Label

  • We’ll use the Garlon 4 (triclopyr)
    label for most of this discussion
  • Note that herbicide labels are
    among the easiest to read
  • (Monsanto’s are the exception)

Labels and Labeling: Supplemental labels

  • Additional sites of allowable use
  • Supplemental labels are easier to generate than a new label
  • But, information from supplemental labels will be incorporated in the next version of the label issued
  • If the use is maintained

Labels and Labeling: The MSDS (Material Safety Data Sheet)

  • Content (specific subjects) is now specified and required by the EPA
  • Categories of information are defined so the information should be easy to find
  • Some older MSDSs are still are available and are often hard to interpret

Labels and Labeling: Note about Aquatic Labels

  • Computation of water volumes often gives applicators trouble
  • Concept of acre foot (see aquatic label section) is confusing
  • So most aquatic labels include a calibration table based on desired application rate and dimensions of the water body

Label revocation

  • Canceled
    • A specific use is no longer allowed by newer labeling – but products with that use listed on them may be used
    • Like a postage stamp – used as originally permitted
  • Suspended
    • Specified uses are no longer permitted regardless of package label
    • Think of a hanging – suspended uses are dead

Labels and Labeling: Labeling

  • Supporting information
  • Produced by the manufacturer
  • Gives technical, environmental, or application (rate or tool) information
