North Dakota Pesticide License Practice Test (Free Core Exam Questions)

Preparing for the North Dakota pesticide applicator exam? In North Dakota, applicator certification and licensing are handled by the state pesticide regulatory agency, generally the North Dakota Department of Agriculture. Like every state, North Dakota 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 North Dakota Department of Agriculture. This site is unofficial and not affiliated with any North Dakota agency.
