If John plans to conduct commodity fumigations using a restricted material in three counties, how many restricted material permits does he need to apply for?

In the context of fumigation practices, particularly when dealing with restricted materials, it is essential to recognize that each county has its own regulations and requirements for the use of these materials. Since John is planning to conduct commodity fumigations in three separate counties, he must apply for a restricted material permit in each of those counties to comply with local regulations.

Each county's agricultural commissioner may impose different restrictions or requirements for the use of restricted materials, necessitating separate permits for adequate oversight. Therefore, conducting fumigation operations in all three counties necessitates three distinct permits, ensuring John adheres to the legal framework governing pesticide use across different jurisdictions. This requirement helps maintain safety and environmental standards specific to each region.
