Pesticide licence in Kentucky: operator, applicator and dealer registration

This page reports what the official source says. It is not legal advice: ask the office named here. The sources are Kentucky Revised Statutes chapter 217B and the administrative regulation 302 KAR 26:020, both published by the Kentucky Legislative Research Commission, plus the federal category list in 40 CFR 171.101. The Kentucky Department of Agriculture runs the programme, but its own site did not answer on October 9, 2026, so nothing here comes from it. The parent page, pesticide licences by country, has the national background.

Operator, applicator and dealer

KRS 217B.070 says nobody may be in the business of applying pesticides to the lands of another without a pesticide operator's licence. The text of KRS 217B.070 sets the fee at US$100 a year, and says the applicant must hold a valid certification in the category and be registered as a dealer or employed by a registered dealer. KRS 217B.080 covers the employee: it is unlawful to apply pesticides as an employee of an operator or dealer without an applicator's licence. That licence costs US$25, and it also needs a valid certification and an employer or supervisor who holds an operator's licence. A licensed operator who passed the exam does not need a separate applicator licence. Both licences expire at the end of the calendar year of issue.

KRS 217B.105 requires a dealer registration for anyone acting as a dealer. The fee is US$75 and each branch office is registered at US$50. Registrations expire December 31 and renew on or before January 1. Under KRS 217B.130 the department does not issue or renew a registration for a dealer who applies pesticides to the lands of others until it has a surety bond or liability insurance policy of not less than US$1,000,000. The department must be told ten days before the bond or policy is reduced or cancelled, and a deductible up to US$1,000 may be accepted. The section adds that the statute does not relieve anyone of liability for damage to another person's land, even when the use followed the regulations.

The ornamental, turf and lawn care category

The department's rule, 302 KAR 26:020 on the Legislative Research Commission site, lists 13 categories in Section 3. Ornamental, turf and lawn care covers people who apply pesticides or impregnated fertiliser to control insects, weeds and diseases in turf, lawns and the maintenance of ornamental trees, shrubs and flowers. It includes pests that do not normally invade structures, with bagworms, grubs and moles as examples. The rule says a licence in this category also qualifies the applicator for interior plantscapes, sports turf and golf courses. Other categories include agricultural pest control, forest pest control, aquatic, right-of-way, structural pest control and public health. The federal list in 40 CFR 171.101 on the eCFR site has a matching ornamental and turf pest control category.

KRS 217B.180 exempts some work from licensing. One exemption covers a person using hand-powered equipment to apply nonrestricted use pesticides to lawns, or to ornamental shrubs and trees not more than 12 feet high, as part of looking after their own or a neighbour's household lawn and yard. It applies only if they do not hold themselves out as being in the pesticide business and take no pay other than a trade of personal services.

Exam, reciprocity and renewal

Section 1 of the rule says a licence goes to nobody under 18, and nobody buys restricted use pesticides without a licence in a matching category. Section 2 requires a passing score of 70% on a written exam in the category. The exam is proctored by a person the department designates, with photo identification or a declaration of identity and age, and only department-approved reference materials. After passing, a candidate has 30 days from the test date to pay the licence fee, or must retake the exam. A trainee registered with the department can apply under direct supervision.

The department may waive certification for a person with a valid licence from another state, tribal or federal agency, but only if that person is employed by a Kentucky-registered dealer and the other agency has substantially similar requirements and reciprocates. The reciprocal fee is US$25. Section 6 requires 12 CEU in the three-year period before the annual renewal, with at least one core-standards topic and one specific-standards topic, and at least one CEU related to each category held. A shortfall means no new licence until the exam is passed again and fees and fines are paid. Section 9 says licences expire on December 31, and a person who has not renewed after January 31 must retest as an initial applicant. KRS 217B.060 gives the exam subjects: equipment, drift, weather, effects on plants and wildlife, pesticide identity, calculating concentrations, pest identification by common name, protective clothing, disposal and cleaning, and state and federal law.
