South Dakota Commercial Pesticide Applicator Certification Testing

By Stephen Robertson

becoming certified. New commercial pesticide applicators and those that have allowed their licenses to lapse must pass commercial pesticide applicator exams to receive commercial pesticide applicator certifications, which make someone eligible to purchase licenses. Here, I provide some helpful resources, contacts, and tips to help you be successful in your certification testing.

Who Needs Certification?

Commercial applicators 1) engage in the business of applying pesticides to the lands of another, 2) advertise as being in the business of applying pesticides to the lands of another at any time, 3) apply pesticides while in the performance of duties as a governmental employee, or 4) otherwise act as a commercial applicator. Because licensed commercial applicators cover more area than average pesticide applicators, may make applications near human population centers, and have access to the most potent of pesticide chemicals and formulations, the possible impact of their applications is extensive. It is because of this risk that commercial pesticide applicators are held to a higher standard than private pesticide applicators and must pass exams to be certification.

Commercial applicator certifications and licenses in South Dakota are split into categories reflecting the nature of the applications being made, such as category 1 for applications to agricultural plants to control agricultural pests and category 15 for applications to wood to control wood-destroying pests. You can find a list of categories in the South Dakota Commercial CERTIFICATION Categories for Pesticide Applicators & Dealers resource.

Seeing the Whole Season: How Continuous Crop Modeling Is Changing Breeding

Video: Seeing the Whole Season: How Continuous Crop Modeling Is Changing Breeding

Plant breeding has long been shaped by snapshots. A walk through a plot. A single set of notes. A yield check at the end of the season. But crops do not grow in moments. They change every day.

In this conversation, Gary Nijak of AerialPLOT explains how continuous crop modeling is changing the way breeders see, measure, and select plants by capturing growth, stress, and recovery across the entire season, not just at isolated points in time.

Nijak breaks down why point-in-time observations can miss critical performance signals, how repeated, season-long data collection removes the human bottleneck in breeding, and what becomes possible when every plot is treated as a living data set. He also explores how continuous modeling allows breeding programs to move beyond vague descriptors and toward measurable, repeatable insights that connect directly to on-farm outcomes.

This conversation explores:

• What continuous crop modeling is and how it works

• Why traditional field observations fall short over a full growing season

• How scale and repeated measurement change breeding decisions

• What “digital twins” of plots mean for selection and performance

• Why data, not hardware, is driving the next shift in breeding innovation As data-driven breeding moves from research into real-world programs, this discussion offers a clear look at how seeing the whole season is reshaping value for breeders, seed companies, and farmers, and why this may be only the beginning.
