When should nozzles be inspected for wear?

Only once a season
After every application
Before the first application of the year
If the flow rate becomes excessive

The correct answer is: If the flow rate becomes excessive

Inspecting nozzles for wear is essential to ensure they function effectively and apply pesticides correctly. Regular inspection is crucial because worn nozzles can lead to uneven distribution, which may affect the effectiveness of pesticide applications and potentially harm the environment or non-target species. The correct choice indicates that nozzles should be inspected specifically if the flow rate becomes excessive. An excessive flow rate may suggest that the nozzle has worn down to a point where it is no longer delivering the intended amount of product, leading to potential over-application. Over time, wear and tear from repeated use can alter the size and shape of the nozzle openings, causing flow rates to change significantly. In contrast, restricting inspections to only once a season or just before the first application does not account for the potential changes in performance throughout the season. Waiting to inspect only after an application can lead to problems during the crucial moments of pesticide application. Therefore, monitoring the flow rate regularly is essential to maintaining proper application rates and ensuring effective pest control.
