Which two categories of pesticide applicators must be certified and licensed after passing a written test?

• A. Commercial and non-commercial
• B. Public and private
• C. Agricultural and residential
• D. Retail and wholesale

Answer: (A)

The concept being tested is which applicator groups must demonstrate formal knowledge before handling pesticides. In Kentucky, certification and licensing focus on those applying pesticides in professional contexts, so the two categories that require passing a written exam and becoming licensed are commercial applicators and non-commercial applicators. Commercial applicators perform pesticide applications as a business or for pay, while non-commercial applicators apply pesticides in settings that aren’t for their own private farming operation but still need to meet regulatory standards (such as organizational or institutional uses). Requiring licensure for these groups ensures they understand label directions, safety, environmental protection, and recordkeeping, reducing risks to people and the environment.

The other pairings don’t align with how Kentucky structures certification: the distinction isn’t based on public vs private ownership, or agricultural vs residential, or retail vs wholesale, but on whether the use is commercial (for compensation) or non-commercial (non-private-use contexts).
