New Hampshire Pesticide License Practice Test (Free Core Exam Questions)

Preparing for the New Hampshire pesticide applicator exam? In New Hampshire, applicator certification and licensing are handled by the state pesticide regulatory agency, generally the New Hampshire Department of Agriculture, Markets and Food. Like every state, New Hampshire requires applicators to show competency in the core (general standards) areas set out in federal rules: label comprehension, safety, environmental protection, pests, pesticides, equipment, application methods, laws, supervision, and professionalism. Most candidates also take a state laws section and one or more category exams.

Confirm current exam requirements, manuals, fees, and testing locations directly with the New Hampshire Department of Agriculture, Markets and Food. This site is unofficial and not affiliated with any New Hampshire agency.
