According to Oregon Revised Statutes, what is required for pesticides to be legally used in Oregon?

For pesticides to be legally used in Oregon, they must be registered with the Oregon Department of Agriculture (ODA) after receiving registration from the Environmental Protection Agency (EPA). This requirement ensures that pesticides meet state-specific safety, efficacy, and environmental standards beyond the federal regulations. The ODA reviews the EPA's evaluation of the pesticide and assesses how it might affect Oregon's unique ecological and agricultural context.

The act of requiring registration at both the federal and state levels adds an additional layer of safety and oversight, ensuring that products used in the state are not only effective but also safe for local agriculture, consumers, and the environment. Thus, registering with the ODA after EPA registration is essential for compliance with Oregon laws and helps maintain effective regulation of pesticide use.

The other answers do address various aspects related to pesticide regulation but do not capture the complete legal requirement. For instance, a pesticide being listed in the Oregon Pesticide Index or approved by local agricultural offices is not sufficient by themselves for legal use, as they do not encompass the necessary registration process with the ODA that follows EPA registration.
