National Core Manual questions plus North Carolina law questions. Not every state rule is covered, so also study your state manual's law section.
Illness soon after a single substantial exposure fits an acute effect. The scenario does not establish repeated exposure, a long delay, or allergic sensitization.
National Core Manual, 2nd ed., 2014 · Ch. 5 Pesticide Hazards and First Aid · p. 90
Dated stock rotation helps use suitable older product before unnecessary aging. Sorting by newness, size, or seal status can leave older stock unused.
National Core Manual, 2nd ed., 2014 · Ch. 8 Transportation, Storage, and Security · p. 143
Rinsate that could injure the intended plants is unsuitable for that mixture. A lower pesticide rate, less odor, or lower pressure does not establish cleaning-agent compatibility.
National Core Manual, 2nd ed., 2014 · Ch. 10 Planning the Pesticide Application · p. 167
A buffer or pH modifier adjusts acidity or alkalinity. Defoamers, drift additives, and stickers address foam, droplet movement, and retention instead.
National Core Manual, 2nd ed., 2014 · Ch. 4 Pesticide Formulations · p. 79
Less soil depth can mean fewer opportunities for adsorption and degradation before groundwater is reached. It does not directly change the pesticide's solubility or acute toxicity.
National Core Manual, 2nd ed., 2014 · Ch. 7 Pesticides in the Environment · p. 129
Repeated counts and damage records show trends that inform treatment decisions. A highest count, fixed date, or single post-treatment count provides a weaker basis.
National Core Manual, 2nd ed., 2014 · Ch. 1 Pest Management · p. 26
Under § 143-452(g), the license is nontransferable and the new operator must have a licensed applicator available before continuing. Buying the business assets does not transfer the seller's applicator license.
N.C. Gen. Stat. Chapter 143, Article 52 · § 143-452(g)
Broadcast application uniformly covers the entire area. Bands, basal treatments, and spots confine placement to particular portions or targets.
National Core Manual, 2nd ed., 2014 · Ch. 11 Pesticide Application Procedures · p. 173
Under § 143-460(29)(e), the exception covers uncompensated volunteer application of general-use pesticides to another's property. Volunteer status does not extend this exception to restricted-use products.
N.C. Gen. Stat. Chapter 143, Article 52 · § 143-460(29)(e)
The same mode of action can impose similar selection pressure despite different brands. Brand names and container concentrations do not establish different biological targets.
National Core Manual, 2nd ed., 2014 · Ch. 1 Pest Management · p. 29
0.75 gal ÷ 300 sq ft × 1,000 sq ft = 2.5 gal per 1,000 sq ft. Keeping 0.75 gal ignores that the reporting area is larger than the test area.
National Core Manual, 2nd ed., 2014 · Ch. 11 Pesticide Application Procedures · p. 178
The radius is 40 ÷ 2 = 20 ft, so area = 3.14 × 20 × 20 = 1,256 sq ft. Using the diameter as the radius gives the incorrect 5,024 sq ft.
National Core Manual, 2nd ed., 2014 · Ch. 11 Pesticide Application Procedures · p. 179
Registration review assesses risk for directed uses. It does not make different methods or concentrations equally safe or replace assessment of the actual site.
National Core Manual, 2nd ed., 2014 · Ch. 2 Federal Pesticide Laws and Regulations · p. 35
WPS stands for Worker Protection Standard. The other choices are not the name of the pesticide worker-protection program.
National Core Manual, 2nd ed., 2014 · Ch. 2 Federal Pesticide Laws and Regulations · p. 40
Residues can remain throughout the spray system and injure a sensitive planting. Clear rinsewater, cleaned tips alone, or loss of odor does not establish complete cleaning.
National Core Manual, 2nd ed., 2014 · Ch. 10 Planning the Pesticide Application · p. 167
The capsule coating regulates release of the active ingredient under the conditions of use. Pass spacing, measuring equipment, and water left in the tank do not describe that release mechanism.
National Core Manual, 2nd ed., 2014 · Ch. 4 Pesticide Formulations · p. 76
The intended site is turf, so its rate and instructions apply. The shrub rate, an average, or the higher listed rate is not established for this lawn use.
National Core Manual, 2nd ed., 2014 · Ch. 10 Planning the Pesticide Application · p. 159
Under § 143-454(b), the licensee must assure compliant pesticide use by employees. Documented training supports supervision but does not transfer the licensee's statutory responsibility.
N.C. Gen. Stat. Chapter 143, Article 52 · § 143-454(b)
An air-purifying respirator relies on oxygen already present in the air. Filtering contaminants does not supply oxygen to correct a deficient atmosphere.
National Core Manual, 2nd ed., 2014 · Ch. 6 Personal Protective Equipment · p. 112
The ingredient statement describes the composition of the formulated product. Its 30% active ingredient is not the tank dilution, expected pest mortality, or amount used per acre.
National Core Manual, 2nd ed., 2014 · Ch. 3 Pesticide Labeling · p. 50
Take a full mock exam (100 Q · Pass 70%). No hints until you submit, then a chapter-by-chapter score.
The core practice on this page stays free. The pass adds what’s hardest to study from the book alone.

Review the national core manual topics below. Each entry shows the practice questions available for that topic. Tap a chapter to practice just that topic; these counts are not official exam weights.
Expect several questions on what the signal word tells you. It reflects the product’s acute toxicity by its most hazardous route of exposure (swallowed, through the skin or inhaled) or its potential for eye and skin injury. It says nothing about long-term effects.
LD50 is the dose that killed half the test animals, in milligrams per kilogram of body weight. The smaller the number, the less it takes, so the more toxic the product.
Skull and crossbones; “poison” in red. Based on oral, dermal or inhalation toxicity.
No skull and crossbones. Can cause permanent damage to skin, eyes or lungs.
Or moderate eye and skin irritation.
Or slight eye and skin irritation. Class IV products need no signal word, though many still say CAUTION.
Labels name the formulation by its letters. Know what each one is and what it needs in the tank: agitation, extra care with dust, or nothing at all.
| Code | Formulation | Remember |
|---|---|---|
| EC / E | Emulsifiable concentrate | Oil-based liquid that forms a milky emulsion in water. |
| S | Solution | Dissolves completely; little or no agitation needed. |
| RTU | Ready-to-use | Already diluted; apply as packaged. |
| F / AF | Flowable | Solid particles suspended in liquid; needs agitation. |
| A | Aerosol | Active ingredient in a solvent, usually at a low percentage. |
| D | Dust | Dry, fine particles; high drift and inhalation risk. |
| G | Granules | Applied dry, often with a spreader; low drift. |
| P / PS | Pellets | Like granules, but particles are uniform in weight and shape. |
| WP / W | Wettable powder | Suspends in water; constant agitation; inhalation risk while mixing. |
| WDG / DF | Water-dispersible granules / dry flowable | Like a wettable powder with less dust. |
| SP / WSP | Soluble powder | Dissolves in water to form a true solution. |
| B | Bait | Active ingredient mixed with food or another attractant. |
| M | Microencapsulated | Coated particles or droplets mixed with water and sprayed; can release slowly. |
Most core exams include a few math questions. They rarely need more than multiplication and division, but units trip people up. Write every unit down and cancel it as you go.
The label rate is 2 pints per acre. Your sprayer is calibrated to apply 20 gallons per acre and the tank holds 100 gallons. How much product goes in a full tank?
A lawn measures 150 ft × 100 ft. The label calls for 1.5 fl oz per 1,000 sq ft. How much product do you need?
North Carolina Core tests general pesticide applicator knowledge and updated state regulations, with 100 questions and a 70% passing score. For commercial certification, use NCSU's certification and licensing guidance to choose the category examinations that match your work alongside Core. Passing Core alone does not qualify you for every type of pesticide application. Settle your licensing route and category choices before booking so you can prepare the right materials and plan which exams to take.
Start with the North Carolina Pesticide Applicator Certification Core Manual. The NCSU R2025 order form lists the book at $40; R2025 dates the order form, so check the book's edition with NCSU before ordering. Exams taken from July 1, 2025 include updated pesticide regulations. NCDA&CS directs candidates to study the five-page regulation summary and the fourteen-page full changes document alongside the manual. Read both supplements and mark where a change affects the rules in your book. Keep them with your study materials so you review the updates as part of Core preparation.
Prepare for closed-book testing. NCDA&CS offers on-site sessions, and Everblue handles the online option. The four-hour on-site session can include several examinations; do not assume it gives you four hours for Core alone. Ask NCDA&CS or your testing provider about the time allowed for your selected exam and delivery option when you book. Read the NCDA&CS exam page for on-site arrangements and its online guidelines before choosing remote testing.
This site's questions cover general knowledge from the National Pesticide Applicator Certification Core Manual; use the official North Carolina manual and regulation supplements for state requirements and the full state syllabus. Practice label reading, protective equipment, pesticide movement and application calculations, then look up any answer you cannot explain. Write down the label condition, safety principle or calculation step you missed. Return to that point in your reading before trying another set, and review the regulation supplements separately rather than judging your readiness from a practice score alone.
NCDA&CS lists Core at $50 on site, with a $26 online charge bringing remote testing to $76. Check the exam and fees pages before your appointment. Payment instructions vary by venue: NCDA&CS describes card acceptance at most Raleigh locations and exact cash, while Rutherford Extension says on-site cash and cards are not accepted. Contact your chosen venue to find out how to pay. For an online appointment, review the official testing instructions in advance and be ready to complete the exam without consulting your manual.
