What are the two main pesticide classifications?
General use and restricted use
General Use Pesticide
Generally have a lower toxicity and have less potential to harm humans or the
environment
Can be bought and used by the public without special permits or restrictions
Restricted Use Pesticide (RUPs)
Might result in an unreasonable adverse effect on human health and/or the
environment
Application by trained persons is required to use these products
This classification will be stated on the label
Pesticide Registration
Since 1988, the EPA has been in charge of this.
A pesticide must have a substantially complete database and must not cause
unreasonable risks to human health or the environment when used in accordance
with its approved label directions and precautions.
4 types of pesticide registration
Section 3 - full federal label
Section 18 - emergency exemptions
Section 24c - special local needs label
, 2
Section 25b - minimum risk pesticides
Pesticide Registration: Section 3 - Full Federal Label
Outlines pesticide registration requirements that manufacturers must follow.
Most pesticides are registered this way
Pesticide Registration: Section 18 - Emergency Exemptions
Allows state and federal agencies to permit an additional use during a short term
pest management crisis in a specific locality.
Manufacturer is not allowed to advertise or promote the use of the product
under this, even though the use is legal.
This is used when there is a crisis and there are no federally registered pesticides
available to control the problem.
Pesticide Registration: Section 24c - Special Local Needs Label
Colorado can register additional uses of a federally listed pesticide.
These uses are for additional distribution and use in a specific area.
These are valid only in the state of issue.
Pesticide Registration: Section 25b - Minimum Risk Pesticides
Can register pesticides that have a very limited set of active and inert ingredients
specified by the EPA, and are not required to have an EPA registration number.
These pesticides are required to be registered with CDA in order to be sold and
used in Colorado.
Certified Operator
Individual who has been recognized by the state, tribe, territory, or agency
responsible for regulating pesticides (in CO this is the CDA) as being competent to
use or supervise the use of restricted use pesticides (RUPs).
Must know how to read a pesticide label and be bale to follow directions to use
them properly and safely
2 categories of certified operators
, 3
Private Applicators
Commercial Applicators
Private certified operator
Individual who uses or supervises the use of RUPs in the production of agricultural
commodities on land owned or rented by him/her or his/her employer
Commercial certified operator
Individual who engages in the business of applying pesticides or operating a
device for hire.
Limited commercial operator
Any person who in the course of conducting a business only in or on property
owned or leased by the person or the person's employer is engaged in applying
RUPs
Food Quality Protection Act (FQPA)
FIFRA was amended in 1996 to include this.
Requires all pesticides meet new health and safety standards - including
determining if pesticide is an endocrine disruptor.
EPA must conclude with reasonable certainty that no harm will come to infants,
children, or other sensitive individuals exposed to pesticides - cumulative effects
must be considered.
Requires EPA to review every registered pesticide on a 15 year cycle.
Public operator
Any agency of the state, county, city, municipality, local government, or political
subdivision which applies RUPs
Pesticide Residues
Particles that remain in small amounts in or on fruits, vegetables, grains, other
foods, and animal feeds.
Pesticide Residue Tolerance
, 4
Maximum limit, set by the EPA, allowed to remain in or on each treated food
commodity.
Aggregate Pesticide Exposure
All possible sources of exposure to the same pesticide
Cumulative Pesticide Exposure
Combined effect from multiple exposures to the same pesticide
Rinsate
A mixture of pesticides diluted by water, solvents, oils, commercial rinsing agents,
or any other substances.
It is produced from cleaning pesticide application equipment or pesticide
containers.
Penalties for breaking pesticide laws
Both civil and criminal charges can be assessed for FIFRA violations.
Federal Food, Drug and Cosmetic Act (FFDCA)
Passed before FIFRA to set maximum residue levels for unavoidable poisonous
substances in food marketed in the US.
Administered by the FDA but the EPA has a role
EPAs role: sets tolerances for pesticide residues on food commodities in the US
FDAs role: Monitors food crops for pesticide residues and enforces the levels set
by the EPA.
Worker Protection Standard (WPS)
Federal regulation passed in 1974 to provide protection to workers who perform
hand labor tasks in fields after a pesticide application.
Recently updated in 2015 to increase protection to workers.
It applies when a pesticide that contains this labeling is used in the production of
agricultural commodities
