Soil-applied chemicals with residual activity can pose off-target risks, which makes the choice that states they always pose risks the most accurate. These chemicals can persist in the soil for extended periods and have the potential to leach into surrounding areas, affecting non-target plants, wildlife, and even water sources.

The residual nature means that even after the intended application period, they can remain active and continue to influence the environment, sometimes leading to unintended consequences far from the original application site. Additionally, factors such as rain, irrigation, and soil characteristics can exacerbate their mobility, increasing the likelihood of off-target effects.

While one might think that these risks could be mitigated by proper application or specific conditions, the inherent qualities of the chemicals themselves, combined with environmental factors, mean that they still pose a significant risk. This understanding emphasizes the need for careful management and application strategies to minimize the potential for unintentional impact on the ecosystem.
