Which application method is likely to require special protective measures?

The application of pesticides in large quantities is likely to require special protective measures due to the potential for increased exposure to both the applicator and the surrounding environment. Larger volumes of pesticides can lead to the risk of drift, runoff, and unintended chemical exposure to non-target organisms, including beneficial insects, wildlife, and humans. Consequently, taking special precautions such as wearing personal protective equipment (PPE), utilizing proper application techniques to minimize spray drift, and implementing measures to avoid contamination of water sources or soil is critical.

In contrast, while other methods may still necessitate certain precautions, the inherent risks associated with applying larger quantities of pesticides particularly heighten the need for protection to ensure safety and compliance with regulations.
