| Streaking isn’t necessarily just a function of swath width. It can be function of highs and lows in the pattern. This relates to all forms of aerial application.
Due to the physics involved, drones really struggle to develop a uniform pattern. There’s very few adjustments that can be made to make it better. The claim of “I sprayed burn down or defoliant and everything died - no streaks” is not proof of uniform application. It’s simply proof that all widths of the swath received the minimum necessary amount of active ingredient necessary to be effective.
In a high disease environment, if you effectively have 18 oz of Quilt Xcel vs 10 oz in other places within the swath, it will streak the crop.
Swath width is one component of uniform application, but it’s not the only consideration.
There’s a reason there’s hardly any pattern testing work/data on drones in general - the results totally undermines the romance.
All methods of application are less than ideal. It all boils down to which is the MOST ideal for your situation. For us, we prefer and pursue uniform application across the majority of the field. A compromised, streaked up application in the high performing parts of the field undermines the outcome of entire growing season.
