What is the result of too wide or too narrow overlapping of spray passes?

When assessing the impact of overlapping spray passes, having either too wide or too narrow overlaps can lead to inconsistent application patterns across the area being treated. Overlapping spray passes incorrectly can result in areas being over-sprayed, where too much product is applied, or under-sprayed, where insufficient product is delivered.

This inconsistency manifests as uneven application patterns, which can ultimately affect the efficacy of the treatment. For instance, plants in over-treated areas may suffer from chemical damage or phytotoxicity, while those in under-treated zones may not receive enough product to be effective, leading to poor pest management or inadequate crop protection.

Understanding this principle emphasizes the importance of precise calibration and planning in aerial spraying operations. Proper overlap ensures that each section of the target area receives the correct dosage of application, promoting a more uniform and effective treatment across the entire field.
