What might cause uneven herbicide application?

Uneven herbicide application can result from skips in the application. This occurs when the applicator misses sections of the turf while spraying, which can lead to inconsistent coverage. Skips can be caused by a variety of operational issues, such as poor calibration of the application equipment, inattention or distractions during application, or inconsistent walking pace by the operator. When certain areas receive no herbicide, while adjacent areas are treated, it inevitably leads to uneven control of the targeted pests or weeds.

In contrast, mixing wet and dry materials, using a manual applicator, and applying during windy conditions can contribute to application challenges but do not directly lead to the scenario of uneven coverage due to missed spots. Mixing materials improperly can affect effectiveness but not distribution pattern, while using a manual applicator typically relies on the user's technique rather than the equipment itself causing skips. Wind can lead to drift but does not inherently create skips in application coverage.
