A placard provides a warning that fumigation is underway. It must contain the signal word from the products label, warning symbols and a fumigation statement. A placard also records the product name, the date and time fumigation began, and the name, address and telephone number of the applicator. Placards are available from the product manufacturer or the internet.

Fumigation works by converting a solid into a lethal gas which is dispersed within an enclosed area and maintained at a prescribed concentration for a specified period to eliminate target pests. In Minnesota, fumigation is commonly used to treat grain infested with pests and to treat soil in potato production.
Fumigation requires several steps:
- Prepare site and determine dose;
- Complete a Fumigation Management Plan (FMP) if required by product label;
- Application;
- Lockout site;
- Monitor and reapply to maintain lethal concentration if necessary;
- Monitor air temperature which may affect fumigation rate;
- Complete fumigation period;
- Aerate fumigated space;
- Collect and deactivate any unused fumigant;
- Dispose of any non hazardous wastes; and
- Clear area for reentry.
The time recommended on the label is the minimum time necessary to complete the fumigation process. The end time cannot be pre-determined because the process could slow down with conditions. End time can only be determined by monitoring fumigant levels in the container over a period of time.
Yes. A fumigant is a pesticide. A pesticide is defined as a substance or mixture of substances intended to prevent, destroy, repel, or mitigate a pest.
The applicator credential in Minnesota is an annual license issued by the MDA. The Minnesota Pesticide Control Law requires that a person obtain a Commercial Pesticide Applicator License to apply a pesticide for hire, or a Noncommercial Pesticide Applicator License to apply any pesticide classified as a restricted use pesticide (RUP) as a condition of employment. Many, but not all fumigants are classified as RUP.
The words “This is a Restricted Use Pesticide” will be written near the top of the product label on the front of the container.
A person using a RUP fumigant in the production of an agricultural commodity on their own property, or as one of two or fewer employees in the production of an agricultural commodity must obtain a Private Pesticide Applicator Certification. Once a person has obtained a Private Pesticide Applicator Certification, they must add a Fumigation Endorsement (either non-soil or soil) which allows them to purchase and use a registered RUP fumigant.
A person must demonstrate that they are competent to hold an applicator credential by passing a closed book exam. A person must also complete an application form for either a Pesticide Applicator License or Private Pesticide Applicator Certification and pay the necessary application fees. A person must meet financial responsibility requirements as defined by the Law to obtain a Commercial Pesticide Applicator License. A Commercial or Noncommercial Pesticide Applicator License issued by the MDA expires on December 31 and must be renewed annually. An MDA issued Private Pesticide Applicator Certification expires on March 1 three years after issue.
The MDA requires licensed persons attend recertification training every other year in order to renew an expired license. A certified Private Pesticide Applicator may attend an approved recertification training every three years or take an exam in order to renew their certification. Recertification for the Fumigation Endorsement is by test only.
Yes. The Law requires that every person obtain a license prior to applying pesticide for hire, or occupationally applying an RUP. A person who applies an RUP on their own property must obtain a private certification and a fumigation endorsement if necessary. The MDA mails an ID card to persons who become licensed or certified. Lists of credentialed applicators can be found in the Online Licensing System.
No. The MDA does not allow a person to apply a pesticide for hire, or to apply RUP without first obtaining the proper credential.
A person without a credential can help with the setup and site preparation prior to fumigation and the clean up activities after the space is cleared and the fumigation is complete. These tasks may include moving unopened product, sealing spaces and placarding in advance of the fumigation application, or breaking seals and disposal of wastes after aeration is complete.
One credentialed person may apply a fumigant when no entry into a structure is necessary to complete the fumigation. Two credentialed persons must be on-site whenever fumigation requires entry into a structure. Only a person with applicator credential (Pesticide Applicator License or Private Applicator Certification with Fumigation Endorsement) is deemed properly trained to apply fumigant and perform the related tasks.
Some fumigant labels now require a FMP. This document which the applicator completes for every fumigation describes the planned fumigation process. The US EPA and manufacturers agreed to adopt the FMP because of the human health risk posed by phosphine fumigants. Product stewardship agreements such as the FMP allow for reregistration of certain products while assuring protections for users and other individuals near the application area.
You may either create an original FMP or use an existing template. Multiple templates are available online. For example, the Nebraska Department of Agriculture (NDA) has a template, Fumigation Management Plan Template | Nebraska Department of Agriculture (PDF).
A person credentialed as an applicator must complete the FMP. It must be specific for each treatment site, up to date, available for review, and carefully followed. Information on the plan includes emergency contact information, personnel credentials and notification, site logistics, application procedures and fumigation period, steps for sealing, posting, monitoring of site and after fumigation procedures. The product Applicator Manual contains a full list of FMP requirements.
No. An FMP is required by the product label. A pesticide application record is required by Minnesota law for certain licensed pesticide applicators. The 1990 Farm Bill requires private pesticide applicators to keep application records of restricted use pesticides applied. Application records require different kinds of information than the FMP.
A pesticide application record documents the application of pesticide at each site where pesticides are applied. When required, a person must complete the record within 5 days of the application, give a copy to the customer where applicable and maintain a copy. The MDA maintains Pesticide Application Record Templates that show the information required.
Commodities in railroad freight cars and ship holds may be fumigated while transported from one location to another. Fumigation is begun at the origination point, continues in transit, and concludes at the destination. The fumigation rate depends on temperature. At conclusion, monitoring shows the absence of fumigant, the container is aerated, unused product deactivated and the container cleared. Fumigation in transit is not permitted in truck trailers moving over the road.
Yes. The shipper/fumigator is required to notify the receiver/fumigator in advance of the shipment that in transit fumigation is underway. The notice can be in written or electronic, and must include a copy of the label, the Applicator Manual and the application record. It allows the receiver/fumigator to prepare for the arrival of the commodity and to complete the fumigation. This notice transfers the application responsibilities to the receiver/fumigator who must complete the fumigation in accordance with applicable laws and regulations, including shipments where the commodities cross state boarders.
Yes. The receiver/fumigator must acknowledge receipt of the notice. Documenting the notification and acknowledgement by both parties show each has done their due diligence.
Minnesota Law holds the applicator and application company responsible for an application. In instances where the shipper and receiver may each be responsible for a portion of the application, the transfer notice and acknowledgement helps clarify responsibilities.
The label and Applicator Manual may be sent prior to the shipment, or secured to containers holding fumigant. Documents accompanying shipments undergoing fumigation must be secured to the containers exterior near placards. Place documents on the first and last rail cars of a continuous and connected line, as long as no intermediate cars will be diverted.
Placarding is an important safety notice to persons who may not be aware the container is undergoing fumigation. A person opening a container unaware that it is holding fumigant could be seriously injured. Placards must be placed on both sides of each rail car or container holding fumigant. Placards must be placed in full view near each ladder and near each hatch. Placards may not be removed until the treated commodity is completely aerated and the application is complete.

In response to economic and environmental concerns, and as a result of increasing educational, cost-share and regulatory programs, the number of livestock producers who test their manure has increased dramatically in the last five to ten years. Despite this trend, many livestock producers still do not test their manure on a regular basis. Difficulties with sampling, variability in test results and concern about the accuracy of nutrient availability estimates have led many producers to question the value of manure testing.
Increased customer demand, the need to fill information gaps and the desire to promote the value of manure testing have resulted in, agricultural laboratories devoting more resources to manure analysis and promotion of their manure testing and nutrient management services. There has been a corresponding laboratory need for information and technical assistance for development and improvement of manure analysis methods, quality control and assurance, reporting and interpretation of results. Extension educators, local governments, private industry and others who work with farmers also desire more and better information about manure sampling and testing. The Manure Testing Laboratory Certification Program was developed in order to help fill these needs.

The MDA implemented a Manure Testing Laboratory Certification Program in 1996 to assist laboratories in ensuring the accuracy and credibility of manure test results, to promote voluntary adoption of manure testing practices, and use of test results in nutrient management planning by livestock producers. These goals are being accomplished through development and use of standardized manure analysis methods; laboratory proficiency testing; information and technical assistance provided to laboratories, educators and private industry; and promotion of manure testing and nutrient management planning services provided by laboratories, dealers, consultants, applicators and others.
