Which application pattern helps avoid flying through spray from a previous swath?

The race track pattern is designed specifically to minimize the risk of flying through spray from a previous swath. This pattern involves flying in a rectangular route that allows the applicator to maintain a consistent flight path and avoid overlapping with the sprayed area. By following this systematic approach, it creates a clear separation between newly applied pesticide or fertilizer and the area that has already been treated, reducing potential drift and ensuring more uniform application.

In contrast, the other patterns may lead to some degree of overlap or less clear separation. For instance, the circular pattern might cause the applicator to inadvertently cross over previously sprayed areas, particularly if winds or other environmental factors change. The zigzag and diagonal patterns can also create situations where an applicator might inadvertently pass through areas that have already been applied, increasing the risk of off-target application. Therefore, the race track pattern is the most effective for maintaining precision and avoiding unwanted exposure to previously applied chemicals.
