32 cards. Read the term and the definition here. The deck at the top of this page is optional.

Private applicator license
An ODA-issued credential authorizing a person to apply or supervise restricted-use pesticides on land they own or rent for agricultural production.
Commercial applicator license
An ODA credential required to apply restricted-use pesticides for hire or on property not owned or rented by the applicator or employer.
Pesticide business license
A license required for a business that applies pesticides for hire in Ohio; it is separate from the individual applicator credential.
Dealer license requirement
A license or registration required to sell restricted-use pesticides; dealers may sell RUPs only to properly certified buyers.
Recertification cycle
The period after which an applicator must renew a credential through continuing education or re-examination to keep the license active.
Label is the law
The principle that pesticide use must conform to the registered label directions; use inconsistent with the label is a legal violation.
Restricted-use pesticide
A pesticide EPA classifies as available only to certified applicators or persons under their direct supervision due to toxicity or environmental hazard.
RUP buyer verification
Before selling an RUP, the dealer must confirm the buyer holds a valid credential covering the product's use category and record the number.
RUP sales record elements
Required entries include product name, EPA registration number, quantity, sale date, buyer name and address, and buyer credential number.
Direct supervision
Uncertified persons may use an RUP only when a certified applicator is physically present and responsible, as stated on the product label.
EPA registration number
A three-part identifier (company, product, distributor/alternate number) used to verify a product is registered and to match sales records.
RUP dealer retention
Dealers must keep RUP sales records for the period set by ODA rule and produce them during inspections or enforcement actions.
FIFRA Section 3 registration
The federal registration process a pesticide must complete before it may be distributed or sold in the United States.
Section 24(c) registration
A special local need registration allowing a state to add a use to a federally registered product for a specific local pest problem.
Section 18 exemption
A temporary EPA exemption permitting unregistered use for a defined area and period when no registered alternative exists.
Experimental use permit
An EPA authorization allowing limited testing of an unregistered pesticide under controlled conditions before registration is granted.
Tolerance requirement
A maximum residue limit that must exist for pesticide residues on food or feed commodities; use inconsistent with it can adulterate the crop.
Misbranded product
A pesticide whose label is false, misleading, or lacks required information; it may not be sold or distributed.
Sprayer calibration formula
GPA = (GPM × 5940) ÷ (MPH × nozzle spacing in inches); used to set a broadcast boom sprayer to deliver the labeled rate.
Application rate formula
Rate = product amount divided by treated area; calibrate equipment to deliver the labeled amount per acre or per 1,000 square feet.
Droplet size and drift
Finer spray droplets increase off-target drift; coarser droplets reduce drift but may reduce coverage on the target surface.
Band application calculation
Rate is based on band width relative to row spacing, reducing total product compared with a broadcast application.
Jar compatibility test
A small-scale test mixing products in water to detect clumping or antagonism before preparing a full tank mix.
Granular spreader calibration
Adjusting spreader settings and swath overlap to achieve uniform granular coverage at the labeled rate.
Aerial applicator credential
A commercial applicator license with the appropriate aerial category, plus compliance with FAA pilot and aircraft requirements.
UAS label authorization
A UAS pesticide application is lawful only if the product label permits aerial application for the intended use and site.
Aerial drift limits
Labels specify droplet size, boom height, wind speed limits, and buffer zones that aerial and UAS applications must follow.
Aerial swath calibration
Adjusting swath width and flow rate to ground speed so the aircraft or UAS delivers the labeled rate per acre.
Aerial application records
Each aerial or UAS application must be recorded with product, rate, area, date, time, and weather conditions for ODA inspection.
RUP application record
A record for each restricted-use application including product, EPA number, rate, date, location, and applicator name.
Record retention period
RUP application and sales records must be kept for the period set by ODA rule and made available to ODA on request.
Electronic recordkeeping
Records may be kept electronically if they are legible, retrievable, and reproducible in a form acceptable to ODA during inspection.
