About this exam

Missouri pesticide certification is issued by the Missouri Department of Agriculture's Pesticide Program under the Missouri Pesticide Use Act, which sets licensing requirements for applicators, dealers, technicians and operators. The credential matters most for anyone who uses restricted use pesticides: commercial applicators who apply pesticides to the lands of another for compensation, noncommercial applicators who apply RUPs only on land they or their employer own or rent, public operators working for government agencies, and private applicators producing agricultural commodities on their own or rented property. Certification rests on examinations delivered through Pearson Vue. Commercial, noncommercial and public operator candidates must pass the General Standards of Competence Examination (CORE) plus at least one category examination. Private applicators can instead complete University of Missouri Extension training, in person or online, for each category in which they will use RUPs. Category 7A, 7B and 7C applicants must also document valid pesticide experience or an associate degree or equivalent in biology, chemistry, agriculture or entomology. Prepare by studying the CORE manual and the manual for each category you need, then booking your Pearson Vue seat at least 24 hours ahead, because walk-ins are not available. After passing, submit the application and any fee through the mail or MOPlants.

Common questions

About MO Pesticide Applicator preparation

How do I schedule the Missouri pesticide exam?

Reserve through Pearson Vue online or by calling (866) 221-6481. Book at least 24 hours before your desired date; walk-in examinations are not available. Study manuals come from the University of Missouri Extension Publication Office, and after passing you submit your application and fee to the Missouri Department of Agriculture or through MOPlants.

Which exams must I pass to become certified?

Commercial, noncommercial and public operator candidates must pass the General Standards of Competence Examination (CORE) and at least one category examination at Pearson Vue. Private applicators may instead complete a University of Missouri Extension training program, in person or online, for each category where restricted use pesticides will be used.

What does certification cost?

Commercial applicator licenses carry a $65 fee. Noncommercial applicator, pesticide dealer, noncertified RUP applicator and pesticide technician licenses each carry a $35 fee. Certified public operator and private applicator licenses require no license fee. Late renewals after expiration add a 25% penalty on top of the original fee.

How long is my certification valid?

Commercial and noncommercial applicator certifications must be renewed every three years, as must public operator certification. Private applicator licenses expire five years from the issue date. Note that the underlying licenses expire more often: commercial and noncommercial licenses annually, while public operator licenses expire every three years.

What happens if I let my license expire?

You may still renew during the 60-day grace period after expiration. Renewing after expiration requires the original license fee plus a 25% late penalty. Licenses and certifications are canceled if not renewed before the grace period ends, so you would start over.

Does Missouri accept certification from another state?

Yes, under formal reciprocity with Kansas, Nebraska, Iowa, Minnesota, Illinois, Arkansas, Louisiana, the Agricultural Aviation Board of Mississippi for categories 1A, 2, 5 and 6, and Tennessee for aerial only. Arkansas excludes ornamental and turf and structural categories; Louisiana excludes structural. You must be a resident and have your state submit a reciprocal form.

What extra requirements apply to structural categories?

Applicants for Category 7A, 7B or 7C must submit evidence of valid experience using pesticides in those categories, or an associate of arts degree or equivalent in biology, chemistry, agriculture or entomology via transcript. The Verification of Structural Pesticide Application Experience Form attests experience. Commercial applicants must also show financial responsibility through insurance, surety bond or the proof of insurance form.

How should I plan my study order?

Start with CORE, since every certified applicator needs it and it underpins safe handling, labels and regulations. Then study the manual for each category on your license. From January 1, 2025, all certified applicators must recertify in all categories listed on their license plus CORE, so skipping a category creates extra work later.

What is the most common way candidates lose time?

Underestimating the CORE exam and the category-specific material, then discovering the 24-hour booking rule or missing documents. Structural applicants who lack transcripts or a completed experience form are delayed even after passing. Also remember that passing an exam does not itself license you; the application and fee must reach the Department or MOPlants.
