What can contribute to distorting distribution from application nozzles?

Over-application of pesticide
Proper cleaning of the nozzle
Using worn nozzles
Adjusting the pressure settings

The correct answer is: Using worn nozzles

Using worn nozzles can significantly contribute to distorting distribution from application nozzles. Over time, nozzles can become damaged or eroded, leading to inconsistent droplet sizes and uneven application patterns. This wear can result in areas of over-application or under-application of the pesticide, affecting both efficacy and safety. In contrast, proper cleaning of the nozzle is essential for maintaining performance and does not contribute to distortion; it helps ensure that the flow rate and spray pattern remain uniform. Adjusting pressure settings can also be managed to optimize application efficiency and minimize distortion, provided they are done correctly and according to the manufacturer's specifications. Over-application of pesticide, while it can lead to other issues, is not specifically related to the physical condition of the nozzle itself.
