Which nozzle type is used most often with systemic products, but can also work with contact products if the spray high volume is greater than 40 GPA?

Which nozzle type is used most often with systemic products, but can also work with contact products if the spray high volume is greater than 40 GPA?

• A. Venturi
• B. Extended range flat-fan
• C. Flooding
• D. Broadcast

Answer: (A)

Venturi nozzles use the Venturi effect to draw concentrate into the water stream, giving a well-mixed spray without needing a separate injector. This makes them a good fit for systemic pesticides, where even distribution and reliable uptake by the plant matter most. At the same time, they tolerate higher spray volumes, and if you’re applying more than 40 gallons per acre, they can also work with contact products because the extra water helps achieve thorough wetting and coverage. Other nozzle types are more about drift control or coarse canopy coverage rather than reliable injection and consistent mixing, which is why they’re not the best match for the common use of systemic products.
