Pesticides: back to basics.
(1) Back to Basics--EPA
* The Environmental Protection Agency (EPA) was established in 1972 to regulate the pesticide industry.
* EPA is responsible for the registration of all active ingredients and end use product forms.
* EPA requires batteries of tests for active ingredients, inert ingredients and for end use products.
* Registrations are granted only after close scrutiny of submitted tests.
* EPA classifies registrations based on the outcome of these tests.
* EPA is basically in the risk assessment business.
* A pesticide is anything that is used to control unwanted species.
** Insecticide -- Insect control
** Herbicide -- Weed control
** Fungicide -- Fungus/bacteria control
** Miticide -- Mite control
* Regulation of pesticides began in 1972.
(3) State Registrations
* States also register pesticides.
* EPA registration is not a universal call to use.
* Most states rubber stamp the EPA but some require additional tests.
* States can levy fines to the registrant, distributor, and end user if a product is sold or used in a state that has not registered the product.
* Pesticides are registered under one of three branches:
** Biochemical -- soft chemistries; genetic engineered organisms, some Insect Growth Regulators
** Office of pesticide programs -- traditional chemistry; pyrethroid, organo-phosphates
** Antimicrobials -- anti-bacterial products
(5) Pesticide Label Components
* The label is the law
** "It is a violation of federal law to use this product in a manner inconsistent with its labeling."
* Labels are broken into four basic areas:
** Active ingredient statement -- % of Al in product
** Precautionary language -- Safety information
** Directions for use -- How, where, when to use
** Storage and disposal -- Conditions to store and what to do with excess or leftover product
(6) Active Ingredient Statement
(S)-Methoprene (CAS #65733-16.6) 33.6% OTHER INGREDIENTS % 66.4% Total 100.0%
*Contains petroleum distillates
This product contains 2.5 lb/gallon (300 grams/liter) (S)-methoprene active ingredient.
EPA Reg No. 2724-427
(7) Precautionary Language
(8) Directions for Use
(9) Storage & Disposal
* Registrations are classified into three categories of precautionary language or signal words. Classifications are made based on the results of the toxicological and environmental studies.
** Caution -- least toxic
** Warning -- moderately toxic
** Danger -- severely toxic (Typically restricted use)
(11) Signal Word
* The lowest category is Caution and this will apply to seemingly low toxicity products, even natural products will carry Caution.
* The signal word is the most prominent sized font on the label and it will appear just below the active ingredient statement.
* The precautionary language appears below the signal word and provides safety information on worker protection, first aid and environmental hazards.
(12) Pesticide Use--Requirements
* Purchase and use of a pesticide may have different requirements for different states.
* Most states require a pesticide applicator's license to buy or use for non-consumer products. This can depend on whether the use is for hire, personal or on-farm
* Restricted use products will require a license to purchase.
* Check with your state Ag department with any questions on use and or purchase.
* Always READ and follow label instructions
** The label will tell you where, when, how much, and in what use pattern to use the product.
** Label tells you what to do in case of an emergency. This includes emergency phone numbers and medical advice.
** Label provides manufacturer contact information.
(13) Worker Protection Standard (WPS)
* Label language that is special for agricultural uses
** "Agricultural Use Requirement"
* Not all products have WPS language
** Consumer, pest control, etc
*** Non-ag uses
*** Some labels have dual uses
**** Only applies to Ag uses
* Safety language; directed at Ag workers
** Contains PPE and REI information
* Reentry Interval (REI)
** Time needed to re-enter a treated area
** Varies on product from 4-24 hours
(14) Worker Protection Language
(15) Pesticide Use
* Pesticides should always be used in a manner consistent with the label.
* The appropriate product should be used for the appropriate pest (i.e. don't use a fungicide as a growth regulator)
* Use the appropriate formulation for the site
** Some products have the same A.I. but different formulas
* Example: Sevin is used to control plant feeding pests as a liquid, but is used on animals as a dust for fleas.
(16) Pesticide Basics--Formulation
* Most active ingredients need to be diluted
* Think of a formulation as a recipe
* Carrier for the active ingredient or ingredients
* Makes application of the active feasible
* Allows the active to be applied in its most efficient manner
(17) Types of Formulations
* Aerosols, foggers
* Emulsifiable concentrates (most common)
* Wettable powders
* Flowables -- water based
(18) Why are There So Many Types?
* Active Ingredient plays major role, based on solubility: liquid or crystalline
* Use patterns, fits for different applications, different pests
* Formulation can affect performance
** Length of residual, knockdown
* Market differentiation
* Pesticide products are an essential element to control pests.
* Pesticides should not be relied on solely to control pests.
* An integrated approach can reduce the amount of pesticides used and reduce the potential for resistance development.
* Pesticides are tools that improve profits, protect valuable commodities, and protect humans and pets from disease transmitting arthropods.
* Mail order, Web purchases are OK as long as the product is registered in the receiving state
** Same is true with foreign sales, outside US products must carry federal and state registration, otherwise it is illegal to purchase or use
* Generic active ingredients must go through the registration process at both the state and federal level
** No rubber stamp with Generic chemistry
(21) Helpful Numbers & Websites
* ChemTrec 1-800-262-2800
** Universal poison and spill hotline
* Manufacturers websites
** Source for labels and MSDS
* State and local Ag extension offices
