The correct choice highlights the importance of understanding how application methods can impact the effectiveness and safety of pesticide applications. Over-application can occur when additional water is used with the intention of ensuring thorough coverage of target species, such as hosing down plants. This practice can inadvertently lead to excess pesticide being applied, which not only can harm non-target organisms and the environment but also can violate regulations and result in economic losses.

For dosage-regulated applications, it is critical to apply the correct amount of pesticide to achieve the desired effect while minimizing risks. Over-application increases the potential for resistance in pests, environmental contamination, and may lead to legal penalties if it exceeds the limits established by regulatory agencies.

On the other hand, proper calibration of equipment, while essential for ensuring accurate dosing, is not a factor that inherently affects dosage-regulated applications in the same way as over-application through hosing. Using organic pesticides and mixing in small batches are also relevant practices but do not directly address the issue of dosage regulation as significantly as the risk associated with over-application.
