Is it true or false that any application method may be used, unless prohibited by the label?

The statement is true. In pest control, it is essential to adhere strictly to the instructions provided on the pesticide label. The label serves as a legal document that outlines the approved application methods for a specific pesticide, including what is permissible under various circumstances. If the label does not explicitly prohibit a method of application, then that method may indeed be used.

This flexibility allows for more tailored pest control strategies that can be adapted to different situations and environments, as long as they comply with the label's guidelines. It is crucial for pest control professionals to understand that while they have the potential to use various application methods, they must always remain within the limits set by the pesticide label to ensure safety and effectiveness.
