Which factor contributes to environmental safety in rangeland pesticide use?

• A. Using biological controls and adhering to label directions.
• B. Ignoring buffer zones.
• C. Over-apply pesticides.
• D. Not reading product labels.

Answer: (A)

Using biological controls and adhering to label directions is the best way to protect the environment when using pesticides on rangeland. Biological controls rely on natural enemies or beneficial microbes to reduce pest numbers with minimal disruption to non-target species, water quality, and soil health, which lowers the need for chemical applications and their potential ecological impact. Following label directions ensures the pesticide is used at the correct rate and timing, with the proper application method, and under required safety and containment measures, including respecting buffer zones and avoiding sensitive areas. Together, these practices minimize drift, runoff, and residues while supporting wildlife, beneficial insects, and water resources. Skipping buffer zones, over-applying, or not reading the label increases environmental risks, such as drift into water bodies, soil and water contamination, harm to non-target organisms, and the development of pesticide resistance.
