What term describes pesticides that remain active in the environment for a long time?

The term that describes pesticides remaining active in the environment for a long duration is "persistent." Persistent pesticides are designed to resist breakdown and degradation processes after application, allowing them to remain in the soil, water, or on plant surfaces for extended periods. This longevity can lead to sustained effects on target pests, beneficial organisms, and the surrounding ecosystem.

Understanding persistence is crucial in landscape maintenance because it directly impacts how long these substances can influence pest populations, their potential for causing harm to non-target organisms, and their implications for environmental health. Knowledge of pesticide persistence is essential for making informed decisions about their use, helping landscapers implement practices that minimize environmental impact while effectively managing pests.
