B. Determines what pests are present, their numbers, and damage levels ✅
C. Guarantees complete pest control
D. Replaces the need for economic thresholds
5. The primary goal of pest resistance management is to:

B. Moderately toxic if inhaled
C. Caution - low toxicity
D. Highly toxic via ingestion, inhalation, or skin contact ✅
11. What does a signal word on a pesticide label communicate?
A. The product's color
, B. The relative acute toxicity hazard ✅
C. The pesticide's price
D. The manufacturer's name
12. A Restricted Use Pesticide (RUP) is classified as such because it:
A. Is available for purchase by the general public without training
B. May cause unreasonable adverse effects unless applied by or under direct
supervision of a certified applicator ✅
C. Is exempt from all EPA registration requirements
D. Is approved exclusively for municipal water treatment
13. The Restricted Entry Interval (REI) listed on a pesticide label indicates:
A. When pests enter a field
B. Minimum time before re-entry without PPE ✅
C. Warnings on product label
D. Best application time
14. A pesticide's half-life refers to:
A. Time to reach target pests
B. Market lifetime
C. Time for half of the chemical to degrade ✅
D. Worker exposure time
15. The "Keep Out of Reach of Children" statement on a pesticide label is an example
of:
