What is the primary method for altering spray volume after pattern testing?

Changing nozzle size is the primary method for altering spray volume after conducting pattern testing. The spray nozzle is designed to control the flow rate and droplet size of a pesticide application, which in turn directly influences the volume of the spray that is delivered to the target area.

By selecting a nozzle with a different size, applicators can increase or decrease the rate at which the pesticide is applied, thereby allowing for more precise application rates tailored to specific crop needs or environmental conditions. Larger nozzles typically increase flow rate, while smaller nozzles reduce it. This aspect of spray technology is critical in ensuring that the right amount of product reaches the intended targets without excess runoff or waste.

Other methods such as adjusting spray pressure, modifying flight speed, or altering tank mix can also affect application, but changing nozzle size is the most effective and immediate way to control spray volume specifically stemming from the results of pattern testing.
