What effect does excessive overlap of spray passes have on an application?

Excessive overlap of spray passes primarily leads to uneven application patterns. When aerial applicators excessively overlap their spray passes, the same area receives more product than intended while adjacent areas may be under-treated or not treated at all. This uneven distribution can lead to problems such as crop damage from over-application, varying insect or weed control effectiveness, and less efficient use of the product, ultimately affecting overall application efficacy.

Additionally, while improved coverage may seem advantageous, it is actually a consequence of inappropriate overlap rather than an intended outcome. Similarly, while it might be assumed that this practice could increase efficacy, the reality is that it can lead to diminishing returns where optimal results are not achieved due to the improper delivery of the product across the field. Flight hazards could theoretically occur in an unrelated context but are not a direct result of overlap in spray passes. Understanding this helps emphasize the importance of calibrated and precise application methods in aerial spraying to ensure uniform and effective coverage across the target area.
