Product Registration and Distribution
Every pesticide distributed or sold in Ohio must be registered with ODA, in addition to holding an EPA registration. State registration is product-specific and tied to the label; the label is the law. Candidates should understand what the label controls and what triggers a violation.
The label and its parts
Know the difference between the brand name, common name, and EPA registration number, and understand that the label's directions for use, restricted-entry intervals, PPE, and use sites define legal use. Off-label use is a violation even if the applicator believes it is safer or more effective. A supplemental or special local need (24(c)) label allows a state-specific use but does not override the federal label's prohibitions.
Distribution rules
Misbranded or adulterated products may not be distributed. A product is misbranded if the label is false or misleading, lacks required information, or the product differs from its registered composition. Dealers and distributors must sell only registered products in properly labeled containers, and repackaging generally requires compliance with labeling rules.
Traps to watch
- Thinking a product legal in another state is automatically legal in Ohio - state registration is separate.
- Assuming a Section 18 emergency exemption or 24(c) label is permanent; these are time- or use-limited.
- Believing that mixing two legal products is always legal - tank-mix directions and label prohibitions matter.
- Forgetting that using a product on a site not listed on the label is a violation regardless of intent.
Rule of thumb: Read the label as a set of permissions, not suggestions. If the site, rate, timing, or PPE is not on the label (or covered by a valid supplemental label), the use is not authorized.
Worked example: A product is registered for corn but a grower wants it on soybeans. The applicator cannot simply apply it - that is an off-label use unless a valid 24(c) or Section 18 authorization covers soybeans.
