Worn nozzle tips produce poor spray patterns and ________ flow rates than new nozzles.

Worn nozzle tips indeed produce poor spray patterns and higher flow rates than new nozzles. As nozzles wear out, their openings become enlarged or misshapen, which can lead to an increase in the amount of pesticide or other liquid that flows through them. This occurs because the fluid is not being atomized as effectively, allowing larger droplets to escape more readily and causing a discrepancy in the intended application.

A new, properly functioning nozzle is designed to deliver a specific flow rate and pattern that optimizes the effectiveness of the spray, ensuring an even distribution of the chemical. In contrast, worn nozzles compromise that efficiency, leading not only to the potential for higher flow but also to uneven coverage which can affect pest control efficacy. Understanding this concept emphasizes the importance of maintaining and regularly replacing nozzles to ensure that applications are made correctly and effectively.
