South Dakota pesticide license for lawn care: every person who sprays needs their own

Your license does not cover the helper on the second truck. The state's Department of Agriculture and Natural Resources (DANR) says on its pesticide applicators page that it does not allow supervisory applications: each person making an application must have their own applicator license. Several states in the state-by-state table add a lower tier so crew can spray general use products under a licensed applicator. South Dakota has none.

Everyone who sprays holds a card, and so does the owner

State law, SDCL 38-21-17, requires a commercial applicator's license for anyone who engages in the business of applying pesticides to the lands of another, or advertises as being in that business at any time. A violation is a Class 2 misdemeanor, and a court can add a civil penalty of up to $5,000 per violation. DANR's page uses the same wording. The rule for ornamental and turf pest control says licensed applicators in that class are certified and licensed to use any pesticide, so general use products on a lawn are included.

Illustration, not a real company: a three-person route pays $35 per person on each two-year license, so $105 per cycle in license fees, plus each person's recertification class. The arithmetic multiplies with every hire, and each hire also brings their own exam, license and class. The workers' comp guide covers what a spraying helper does to your policy.

No insurance filing, but the damage claim clock is short

None of the DANR pages, the application form or the chapter 38-21 section headings we read mentions an insurance certificate or bond for the license. That doesn't remove the exposure. SDCL 38-21-45 says following the rules does not relieve anyone from liability for damage caused by pesticides. Under 38-21-46, a person claiming damage must notify the applicator by certified mail within 30 days of when the damage was or should have been observed, and 38-21-47 lets the applicator and up to four representatives enter the property to inspect it.

So a customer whose lawn browns after a treatment can open a claim with a certified letter, and the statute gives that customer 30 days from when the damage was or should have been noticed to send it. Since the state asks for no coverage, the endorsement that answers that claim is your call, and the pesticide applicator insurance guide covers it. The general liability guide and the certificate of insurance guide cover the rest of your coverage and what customers ask to see.

Three steps, in order

1. Study the Core and the turf material. DANR's category list says every tester takes category G, General, plus the categories that match their work. Lawns, parks and the ornamentals inside them fall under category 4, Ornamental and Turf. DANR calls the EPA-hosted National Pesticide Applicator Certification Core Manual a useful resource.
2. Make an exam appointment. DANR lists county and regional testing sites, with the SDSU Testing Center in Brookings among them. Exams are written, and 70 percent passes under rule 12:56:05:02. A failed exam can be retaken three days after notice. The pages we read give no fee for initial exams.
3. Pay for the license once you hold current certification categories. DANR's page says the fee is $35 and can be paid online or by check with the license application form. Under the statute the license expires March 31 of the second year after it was issued.

Fees are as the DANR page and application form read on 2026-10-01. The ornamental and turf exam covers phytotoxicity across many plant types, drift, persistence past the intended control period and non-target exposure, according to the rule that sets its standards.

Two years, then a class or a retest

Certification and the license both run two years. DANR says to recertify and renew by the last day of February in the year of expiration, a month before the statutory March 31 expiration. DANR's renewal flowchart for the 2026 season, open December 3, 2025 through February 28, 2026, lists three paths: an in-person class at $65, an online course at $15 per category, or retaking the exams in state with no fee listed. For the turf categories the 2026 in-person classes were February 12 in Sioux Falls and February 25 in Rapid City. Dates for the 2027 season weren't posted on the pages we read.

Missing the window costs more than the class would have. The flowchart says categories that expire unrenewed require retaking the certification exams, and the license is invalid until then. The statute says a license that lapses must be earned again by exam. If your South Dakota certification came by reciprocity from Iowa, Minnesota, Montana, North Dakota, Nebraska or Wyoming, you renew it with a reciprocity request instead of a class.

Records and what customers can request

Rule 12:56:07:01 asks for a record of every application: customer name and address, location, target pest, area treated, date and time, who applied, product trade and common name, the label's company name, wind direction and speed with temperature, amount and concentration, and the site. Records are kept for three years and must be ready for inspection at the close of each day. A customer who asks in writing is entitled to a record of each application to their land.

Fertilizer-only work isn't covered by any DANR page we read.
