Once your sprayer is calibrated, its delivery rate will remain constant.

The statement that once a sprayer is calibrated, its delivery rate will remain constant is false because various factors can affect the consistency of the delivery rate over time. While calibration sets the sprayer to deliver a specific amount at the outset, several conditions can cause changes in the delivery rate.

For instance, variations such as changes in the viscosity of the pesticide being used, clogging of nozzles, shifts in pressure due to pump wear or maintenance issues, and environmental factors like temperature can all impact how much chemical is actually delivered during application. Additionally, operator technique and equipment adjustments can introduce variability.

Understanding this helps applicators realize that regular monitoring and maintenance are key to ensuring the sprayer continues to perform as intended. Therefore, it is important to frequently check delivery rates and recalibrate if necessary to maintain effective pest control.
