Missouri Pesticide Applicators Exam
Exam Coverage Summary
The Missouri Pesticide Applicator certification is administered by the Missouri Department of
Agriculture's Bureau of Pesticide Control in coordination with the University of Missouri Extension . All
applicators must demonstrate competency by passing the CORE examination, which covers general
standards of competence including label comprehension, safety, environmental protection, pest
identification, pesticide characteristics, equipment calibration, application techniques, laws and
regulations, stewardship, and agricultural pest control . Commercial, noncommercial, and public
operator applicants must also pass at least one category examination specific to their work . Private
applicators (farmers applying RUPs on their own land) must obtain certification in Category 20 - General
Agricultural Pest Control . Key exam topics include reading and understanding pesticide labels (including
signal words, classification, and use restrictions), proper PPE selection and use, preventing pesticide drift
and runoff, avoiding pesticide resistance through mode of action rotation, understanding LD50 and
acute vs. chronic toxicity, safe mixing, loading, storage, transport, and disposal procedures, Missouri-
specific regulations (effective Jan 1, 2025), and integrated pest management (IPM) principles .
Question 1
