Nozzle Technology
• Nozzles designed to reduce drift• Improved drop size control• Emphasis on ‘Spray Quality’

Nozzles are important because:
• Control the amount – GPA.• Determine uniformity of application.
• Affects the coverage.• Influences the drift potential.

Final thoughts:• Due to weather, all nozzle produce small
droplets– high temperature, low humidity = high temperature, low humidity =
smaller dropssmaller drops– evaporationevaporation
• Match nozzle to pest – watch for drift• Venturi tips
– Good for systemic or contact herbicides.Good for systemic or contact herbicides.– Performance over a wide range of Performance over a wide range of
