What defines a prohibited pesticide?

A prohibited pesticide is defined as one that is deemed hazardous and whose use is not allowed under any circumstances. This classification is usually based on its potential to cause harm to human health, non-target organisms, or the environment. Regulatory bodies establish guidelines that identify certain chemicals as too dangerous to use, reflecting their potential for significant negative impacts.

The other options highlight different aspects of pesticide usage. Limited application pesticides are still allowed but restricted in scope. Those effective in small amounts may still be permissible under certain guidelines. Pesticides requiring special permits might still be used legally, but under stringent regulations. In contrast, a prohibited pesticide cannot be used at all, underscoring its status as a significant risk and reinforcing the importance of adhering to regulatory standards for pesticide safety.
