When applying herbicides, what should be avoided to reduce negative impacts?

Avoiding drift and runoff during herbicide applications is crucial for minimizing negative impacts on the environment and ensuring that the herbicides are effective. Drift refers to the unintended movement of herbicides through the air to non-target areas, which can harm surrounding vegetation, wildlife, and beneficial organisms. Runoff occurs when rain or irrigation water carries the herbicide from the application site into water bodies or other areas where it is not intended, potentially contaminating water supplies and harming aquatic ecosystems.

By focusing on preventing drift and runoff, applicators can better protect sensitive areas and maintain the efficacy of the herbicides used. This includes techniques such as using appropriate nozzle types, adjusting application rates based on environmental conditions, and employing buffers or barriers to prevent movement. Understanding this principle is crucial for responsible pesticide application and for complying with environmental regulations.
