The statement regarding the selection of nozzle material based on the pesticide formulation is accurate because different formulations can have varying chemical properties that affect compatibility with nozzle materials. Certain pesticides may be corrosive or abrasive, which necessitates the use of resistant materials like stainless steel or specific plastics to prolong the life of the nozzle and ensure effective application. Using the appropriate material helps to prevent degradation of the nozzle, which can lead to malfunctions or contamination of the pesticide being applied.

Other options do not accurately convey the relationship between nozzle selection and operational effectiveness. For example, while nozzle size and pressure are connected, it’s crucial to consider a broader range of factors such as flow rate and desired droplet size. Selecting nozzle material solely based on the target pest does not encompass the necessity for compatibility with the pesticide itself. Additionally, nozzles cannot universally accommodate all pesticide formulations, as some may need specific designs or materials to function effectively with particular chemicals. Therefore, focusing on the right material for the pesticide formulation is essential for safe and effective pesticide application.
