EvenSpray 80°
• Suitable for knapsack applications of most products.
• Uniform distribution across the spray width ensuring
targets receive an even application of chemical.
• Mixed droplet spectrum for effective delivery and
retention of agrochemicals.

Knapsack calibration
• Where nozzles are specifically designed for knapsack
spraying (e.g. Polijet, DeflecTip and FCX), the speeds
given in the charts are walking speeds.
• For other nozzles the Flow rate or Application rate can
be calculated using the following formulae:
Flow rate
=
L/min
(Application rate (l/ha) x Speed (km/h x Swath width* (m)) ÷ 600
Application rate
L/Ha
=
60,000 x Flow Rate (l/min)
Speed (km/h) x Swath width* (m ) x 100
* At 50 cm nozzle height above ground
