Discuss key signal words and safety precautions on pesticide labels.
Understanding Pesticide Labels
The Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) mandates label language and standards. The Environmental Protection Agency (EPA) is responsible for interpreting labeling standards and ensures that they are followed
The Label is the Law. “It is a violation of Federal law to use this product in a manner inconsistent with its labeling.”
Understanding Pesticide Labels
Required label information that must be on the label which is on or ‘securely attached’ to the container
Reading a Pesticide Label
Restricted Use Pesticide Statement (if applicable) General pesticides
Purchased and applied by the general public Restricted pesticides
Purchased by a licensed certified applicator only. It may be applied by or under the direct supervision of a licensed certified
applicator
Includes the trade, brand or product name Example is Ortho
Ingredient Statement – name and percentage by weight of each active ingredient and percentage by weight of other inert ingredients

KOOROC Statement – hazard statement “Keep Out Of Reach Of Children” on almost all end-use products
Signal word – appear on front panel of the label and are determined by the most severe toxicity category the pesticide meets or by the presence of methanol at a greater level than 4% Danger Warning Caution
Signal Words
Danger (not all danger pesticides have skull and crossbones)It is highly toxic in at least one category – orally,
dermally, through inhalation and/or causes severe eye or skin burn
Toxicity category I – from a few drops to less than a teaspoon may be lethal if swallowed (oral toxicity)
Signal Words
WarningIs moderately toxic in at least one category – orally,
dermally, through inhalation, and moderate eye and skin irritation
Toxicity category II – from one teaspoon to a tablespoon may be lethal if swallowed (oral toxicity)
Signal Words
CautionIs slightly toxic to relatively non-toxic orally, dermally,
or through inhalation, or causes slight eye and skin irritation
Toxicity category III – from one ounce to over a pint may be swallowed before being lethal (oral toxicity)
Skull and Crossbones Symbol
When you see a Skull and Crossbones Symbol and the word Poison (written in red)Only found on pesticides identified as Category I
Toxicity (most deadly)Based on at least one acute toxicity rating for acute
oral, acute dermal, or acute inhalation, or contains more than 4% methanol
Reading a Pesticide Label
First Aid Statement – statement of practical treatment states what to do if a person swallows or is poisoned by spilling the chemical on the skinThis section will also have the toll free phone number
for the National Pesticides Information CenterNet contents/Net weight – measure of contents
Reading a Pesticide Label
EPA Registration Number and EPA Establishment Number – identifies the facility that produced the productAllows for tracking products
Company Name and Address – identifies who produced or registered the product
Reading a Pesticide Label
Precautionary Statements including:Hazards to Humans and Domestic Animals – identifies
the particular route and rate of exposure as well as precautions
First Aid – for various routes of exposureEnvironmental Hazard – indicates that the product may
have undesirable effects in the environment (non-target organisms) especially to wildlife such as bees, fish, and birds
Physical or Chemical Hazard – informs individuals of specific fire or explosion hazards
Reading a Pesticide Label
Directions for use – including mixing and application for various pests. Tells how to legally use and how the product must not be used and includes information about the site, pest(s) controlled, application method, rate of application, and timing of application May Include Worker Protection procedures
PPE – personal protective equipment Examples : masks, coveralls, respirators, gloves, safety glasses or goggles,
rubber boots Reentry time may be in this section as well – how much time must pass before
reentering a treated area Storage and Disposal instructions Warranty Statement
General Information
Referral Statement to Directions for Use in booklet, if any (supplemental labeling)
“Securely attached” means the label can reasonably be expected to remain affixed during the foreseeable conditions and period of use
General Environmental Statement states to watch for run off, avoid applying on windy days and keep pesticides out of storm water sewer drains
Pesticide Safety
The most important rule in pesticide safety is to read and follow all directions on the pesticide label because all other rules are included in this one

Pesticide Classification
General Use Can be purchased and applied by the general public
Restricted UseCan be purchased by a license certified applicator only,
but may be applied by or under the direct supervision of a licensed certified applicator
UnclassifiedPesticides are those that do not meet minimum
requirements to be included in general use pesticides
Types of Pesticides
Insecticide – kills insectsHerbicide – kills unwanted plants
Selective herbicides kill specific weeds or plantsNon-selective herbicides kill all plants with which they
come in contactFungicide – controls fungiOthers – rodenticides, molluscicides, etc.
Pesticide Forms of Substance
Dust – most contain low percentage of active ingredient with dry, inert carrier made from talc, chalk, clay
Wettable powder – (dry – sprayable) - a solid pesticide formulation – micronized to powder form and typically applied as suspended particles after dispersion in water
Fumigant – gases, Methyl bromide is banned, extremely deadly and harmful to environment
Liquid – includes Emulsifiable Concentrates (EC), Solutions (S), Ready-to-use Low Concentration Solutions (RTU), Ultra-Low Volume (ULV), Flowables (F)/Liquids (L)
Granular – large pieces of pesticide (baits)
REMEMBER!!
SAFETY IS THE MOST IMPORTANT CONSIDERATION WHEN WORKING WITH ANY PESTICIDE.
MOST IMPORTANT SAFETY RULE IS ‘READ AND FOLLOW LABEL DIRECTIONS’. ALL THE RULES ARE INCLUDED IN THIS ONE RULE!
