Restricted pesticide handler definition addition provision and restricted pesticide license requirements for handlers modifications

This bill clarifies who qualifies as a "handler" for restricted pesticides in Minnesota. It adds a definition specifying that a "handler" must meet federal requirements and work under a licensed applicator's supervision during preapplication mixing and loading activities. The bill modifies license requirements to explicitly state that handlers can perform these specific tasks only when supervised, while still requiring all restricted pesticide users to hold proper licenses. This directly affects pesticide handlers and licensed applicators who oversee mixing and loading operations. The changes align Minnesota's rules with federal standards (40 CFR § 171.201) for these activities.
