For sprayer nozzles, which factor should be considered when selecting nozzle material?

• A. Pesticide formulation
• B. Nozzle color
• C. Brand loyalty
• D. Season of application

Answer: (A)

Choosing nozzle material depends on chemical compatibility with the pesticide formulation. Different formulations contain solvents, acids or bases, surfactants, and pigments that can attack certain materials. If the material isn’t compatible, it can corrode, degrade, or wear more quickly, altering spray characteristics like droplet size and distribution and potentially causing leaks. So, always refer to the pesticide label or SDS for compatibility and select a nozzle material that resists those chemicals—stainless steel or certain polymers are commonly used for aggressive formulations, while some metals like brass may not hold up. The color of the nozzle, brand loyalty, or the season of application don’t determine material performance in the same way.
