Pesticide Safety & Regulations
Commercial applicators must be certified to use or supervise the use of pesticides which are registered for restricted-use only. Certification of pesticide applicators is designed to ensure that users of these pesticides have sufficient competence to use these materials without injuring humans or the environment.
After October 21, 1977, pesticides registered for restricted-use were generally available only to certified applicators. Tennessee has developed a certification program and set standards that meet the minimum requirements of federal standards.
