North Dakota pesticide license for lawn care: one certification, no business license

North Dakota will take a notarized letter from a CPA or a bank officer in place of a liability policy, and we found no business license to buy. The $100,000 financial responsibility rule can be met three ways, and a letter attesting to net assets is one of them. The state agency does not even run the exams: the North Dakota Department of Agriculture regulates pesticides but does not test or certify anyone. Its applicator certification page says certification and training are run by the NDSU Extension Pesticide Certification and Training Program, and gives a phone number and a link to NDSU. The real application is a university store, a county Extension office and a one-page financial form.

The person is certified, and we found no business license

Under the state's pesticide control chapter, NDCC 4.1-33, a commercial applicator is anyone who applies pesticides for compensation by contract or for hire. Section 4.1-33-07 bars a commercial applicator from purchasing, using or supervising the use of a pesticide without first meeting the certification standards. It does not stop at restricted use products, which matters for a mower route that sprays an over-the-counter weed killer on the side.

The Administrative Code, chapter 60-03-01, says a certificate goes to someone who passes a core exam and is certified in one or more classes. For lawns that class is Ornamental and Turf Pest Control, defined as using pesticides to control pests in the maintenance and production of ornamental plants and turf. The applicant must be 18. Neither the statute nor the NDSU and NDDA pages we read describes a business license or company registration. Many states in the state-by-state table add one on top of the personal license, so don't assume a crew that works across the border from Minnesota or South Dakota is covered by the same paperwork.

Order the study materials, then book the exam at a county office

Start at the NDSU Extension pesticide program page. It tells new applicants to order Commercial study materials, then book an exam by appointment at a local NDSU County Extension Office. NDSU notes that county offices are run by county government, so each may set its own procedures for giving exams. Call before you drive.

The NDSU store's study materials listing puts the fees this way: a $75 base fee plus $25 for each category, with three years of certification fees paid in advance, and exams completed by the end of the calendar year. Materials come by USPS. A brand-new applicant can add the $30 Introductory Basic Core Online Training, which the store describes as more than 30 hours of video.

On the order form in the 2026-27 training book, Ornamental and Turf is a single checkbox and shipping is $15. Ordering only that box comes to $75 plus $25 plus $15, or $115, by our arithmetic; the pages don't say whether the Core is billed as a category. Fees as read on the NDSU store and form on 2026-10-01.

The pass mark for the commercial exams isn't stated on the pages we read. Under the code a failed exam can be retaken after three days.

$100,000 can be met by a policy, a bond or a letter

NDCC 4.1-33-10 bars issuing a commercial certificate until the applicant shows $100,000 in financial responsibility. It names three ways: a notarized letter from a financial institution officer or a CPA attesting to at least $100,000 in net assets, a performance bond, or a general liability policy. A bond or policy must oblige the issuer to tell the agriculture commissioner at least ten days before it cancels.

NDSU supplies an acknowledgment form where you sign a statement that you maintain that amount and will give the commissioner proof on request. The commissioner can stop an application in progress until you produce it, and must suspend the certification of anyone who lapses. Employees of a compliant commercial applicator are exempt from the requirement.

The statute says only "a general liability insurance policy." It says nothing on pollution exclusions or damage to the lawn you treated, and a mowing policy often has both gaps, as the pesticide applicator insurance guide explains. Signing the form doesn't fill them. The general liability guide covers what a standard policy leaves out.

Helpers can spray under supervision, and records last three years

Certification requirements don't apply to a person applying non-restricted pesticides under the direct supervision of a certified commercial applicator, under section 4.1-33-16, unless the label demands a certified person apply it. Direct supervision means the helper acts on the certified person's instruction, and the certified person is physically available, though not necessarily on site. Keep application records for three years under 4.1-33-14. If you add crew for spraying season, the workers' comp guide covers when helpers trigger coverage.

Certificates expire April 1, every third year

Under chapter 60-03-01 a certificate expires on the April 1 after the third anniversary of certification or recertification, and you recertify at least every third year by an approved training or an exam. NDSU's training book says certificates in the current cycle expire April 1, 2027, and warns against waiting until March 31. The Ornamental and Turf renewal course renews your Core too. The store lists it on four dates, each at $75: November 19, 2026 (webinar), January 26, 2027 (Fargo), February 25, 2027 (hosted at Bismarck, Dickinson, Fargo, Grand Forks and Minot county sites), and March 11, 2027 (webinar). Pre-registration is required, a $25 late fee applies after the deadline, and you must attend the full session or be rescheduled if you are more than 15 minutes late.

Fertilizer-only licensing is not stated, and customers can look you up

The Department's pesticide and fertilizer division page says its fertilizer side licenses distributors and anhydrous ammonia storage and registers products. A license for fertilizer-only lawn applicators isn't stated on the pages we read. NDSU runs a public certification record lookup if a customer wants to check yours.
