What is a consequence of too wide or too narrow overlapping of spray passes?

The consequence of too wide or too narrow overlapping of spray passes is primarily uneven application patterns. Proper overlap is crucial in ensuring that the target area receives a consistent and adequate spray coverage. If the overlap is too wide, certain areas can receive excessive amounts of the product, leading to potential phytotoxicity or other issues associated with overdosing. On the other hand, if the overlap is too narrow, some areas may not be sprayed sufficiently, resulting in missed spots and insufficient control of pests or diseases.

Achieving the right balance in spray passes is vital for effective aerial application. Uneven application not only compromises the effectiveness of the treatment but may also lead to increased resistance in pests due to inconsistent exposure to the pesticide. Thus, the focus on maintaining the correct overlap is essential for both operational efficiency and agricultural efficacy.
