Any Private Pesticide Applicator in Minnesota using fumigants in an on-farm operation for stored grain or to fumigate a field (soil fumigation) must be a currently certified private pesticide applicator and also obtain either a Stored Grain and Fumigation Endorsement or a Soil Fumigation Endorsement for Private Pesticide Applicator Certification.
Fumigant labels require applicators to comply with specified safety practices and required personal protective equipment. Applicators must follow fumigant label use directions to minimize health and environmental risks. Good grain storage practices can reduce the need to fumigate stored grain. Purchase of stored grain fumigants requires proof of Private Applicator Certification and Fumigation Endorsement.
The Environmental Protection Agency has reclassified all soil fumigants into the restricted use category. Soil fumigation use in Minnesota is limited to just a few active ingredients.
When Private Pesticide Applicator Certification expires a person must retest or attend a recertification workshop and pay fees to renew.
Grain fumigants: To receive private Stored Grain and Fumigation Endorsement you must pass a closed book test administered by the Minnesota Department of Agriculture (MDA) or a County Agricultural Inspector.
Soil fumigants: To receive private Soil Fumigation Endorsement you must pass a closed book test administered by the MDA. This endorsement expires along with the date of your Private Pesticide Applicator certification, regardless of when the endorsement is acquired.
Locations: The MDA has testing locations in Saint Paul, Fergus Falls or Saint Cloud.
Re-endorsement: A person can recertify for an endorsement by retest. Fumigation re-endorsement is the same as the initial endorsement. There is no charge for Private Applicators to take the Grain or Soil Fumigation exam. There is a $5.00 charge to reprint identification cards with new dates of endorsement. To avoid duplicate fees, the MDA will delay printing your identification card until you pass the Fumigation Endorsement exam. Please contact the MDA Licensing & Certification Unit at 651/201-6615 for information.
Before purchasing any fumigant, you must read and follow all label instructions. Fumigant labels identify what you must do in order to apply the product effectively and in order to minimize health and environmental risk. Labels will specify the required Personal Protective Equipment and whether a Fumigant Management Plan is needed. See the links below for additional information.
