What is a common use of adjuvants in herbicide applications?

Adjuvants play a significant role in enhancing the effectiveness of herbicide applications by improving both the spray pattern and the adhesion of herbicides to the target surfaces. They are often included in pesticide formulations or applied separately to optimize performance.

By improving the spray pattern, adjuvants help ensure uniform coverage, which is critical for the herbicide to contact and effectively penetrate the plant tissue. This increases the likelihood of achieving the intended control of the target vegetation. Additionally, better adhesion means that the herbicide is less likely to runoff or evaporate before it can be absorbed by the plants, making the application more efficient and effective.

While other options describe various processes, they do not directly relate to the primary function of adjuvants in herbicide applications, which is to enhance coverage and adherence to the plant.
