Sample Certified Pesticide Applicator Practice Questions

Try these questions from our free Certified Pesticide Applicator practice tests. The correct answer and an explanation follow each question.

  1. While tank-mixing two different pesticides, Applicator A notes that Pesticide #1 requires a long-sleeve shirt, pants, and waterproof gloves. Pesticide #2 requires coveralls over a shirt and pants, chemical-resistant gloves, and protective eyewear. What is the legally required minimum PPE for Applicator A?

    • A. The PPE listed on Pesticide #1's label.
    • B. A combination of the least restrictive items from both labels.
    • C. Coveralls, a shirt and pants, chemical-resistant gloves, and protective eyewear.
    • D. The applicator can choose which label to follow.

Answer: C. Coveralls, a shirt and pants, chemical-resistant gloves, and protective eyewear.

When mixing multiple pesticides, the applicator must always follow the most restrictive PPE requirements listed on any of the product labels. In this scenario, Pesticide #2 has the more stringent requirements (coveralls, chemical-resistant gloves, eyewear), which must be followed to ensure adequate protection.

  • A pesticide applicator needs to identify the facility where the pesticide product was manufactured. Which number on the label provides this specific information?

    • A. The EPA Registration Number.
    • B. The EPA Establishment Number.
    • C. The Active Ingredient CAS Number.
    • D. The Manufacturer's Lot Number.
  • Answer: B. The EPA Establishment Number.

    The EPA Establishment Number (EPA Est. No.) identifies the specific facility where the pesticide product was produced. The EPA Registration Number identifies the product itself and the company that registered it.

  • An applicator is preparing to mix and load a pesticide with the signal word 'DANGER' on the label. The label instructions for PPE have been worn off and are unreadable. What is the MINIMUM PPE the applicator should wear?

    • A. A long-sleeved shirt, long pants, shoes, and socks.
    • B. Chemical-resistant gloves, coveralls over a long-sleeved shirt and long pants, socks, and chemical-resistant footwear.
    • C. A long-sleeved shirt, long pants, waterproof gloves, shoes, socks, and protective eyewear.
    • D. Just a respirator, as inhalation is the primary concern with highly toxic pesticides.
  • Answer: C. A long-sleeved shirt, long pants, waterproof gloves, shoes, socks, and protective eyewear.

    When a pesticide label does not specify PPE, applicators should still wear at a minimum: a long-sleeved shirt, long pants, chemical-resistant gloves, closed-toe shoes with socks, and protective eyewear, especially when handling concentrates. Given the high toxicity indicated by the 'DANGER' signal word, this level of protection is a crucial baseline.

  • An applicator is preparing to spray a systemic herbicide on a field with very hard water. The pesticide label recommends adding an adjuvant to ensure effectiveness. Which type of adjuvant would be most appropriate to address the hard water and improve pesticide uptake?

    • A. A defoaming agent
    • B. A sticker
    • C. A nitrogen-based fertilizer like Ammonium Sulfate (AMS)
    • D. A thickening agent
  • Answer: C. A nitrogen-based fertilizer like Ammonium Sulfate (AMS)

    Ammonium Sulfate (AMS) is a nitrogen-based fertilizer that functions as a water-conditioning adjuvant. The sulfate ions in AMS bind with minerals like calcium and magnesium found in hard water, preventing them from interfering with the herbicide's activity. Additionally, nitrogen-based adjuvants can enhance the uptake of some systemic herbicides.
