Iowa State Extension Office Program Director Dale Miller tells KNIA KRLS News that the time is close to renew your private pesticide applicator certification. Miller says one way to renew is by attending a private applicators continuing education course during each of the three years during your renewal cycle. Another way is to pass the certification test, every three years. For more information, go to the extension website at www.extension.iastate.edu/marion, or call the extension office at 641-842-2014.
