North Carolina Pesticide Application Practice Test 2025 – Comprehensive Exam Prep

One disadvantage of using pesticides is that pests can become resistant over time. This resistance occurs when pests are exposed to a pesticide repeatedly, allowing those individuals with genetic traits that confer survival against the chemical to reproduce. As a result, the population gradually shifts towards these resistant individuals, making the pesticide less effective in controlling them. This evolutionary process often leads to the need for stronger chemicals or alternative pest control methods, which can increase costs and ecological risks associated with pest management.

In contrast, the other options present misconceptions about pesticide use. Pesticides are not always effective, as their effectiveness can be affected by several factors, including the timing of application, pest growth stages, and environmental conditions. Pesticides are not universally safe for all species; they can harm beneficial insects, wildlife, and even humans if not used properly. Lastly, pesticides typically require the maintenance of application records to track usage and comply with regulatory requirements, which is an important aspect of sustainable pest management and helps to ensure safe practices.
