Which pesticides require a special county permit through the NOI?

The requirement for a special county permit through the Notice of Intent (NOI) typically applies to certain restricted-use pesticides that pose significant risks to human health and the environment. Fumitoxin, zinc phosphide, and strychnine are specifically classified as such due to their potential for acute toxicity and environmental impacts. These substances often require heightened regulatory oversight and strict adherence to application protocols, which is why a special permit is necessary for their use.

In contrast, herbicides, while they may have restrictions, do not require the same level of scrutiny as the chemicals in the correct option. Moreover, stating that any commonly used pesticide or just organic pesticides would require a similar permit does not accurately reflect regulatory requirements, which are focused on the safety and environmental impact of specific substances rather than their general popularity or classification. Therefore, the emphasis on the specific toxic substances aligns with legal and safety regulations regarding pesticide usage.
