Pressure is integral to nozzle performance. Reducing hydraulic pressure reduces nozzle flow rate, increases median droplet size, and typically reduces spray fan angle. Increasing pressure increases nozzle flow rate, reduces median droplet size and typically increases spray fan angle. You can watch this Exploding Sprayer Myths video to learn how pressure, boom height and nozzle spacing […]
“Sprayer calibration is an important part of any crop protection program.” Everyone says so, so it must be important. But what exactly are they asking you to do, and why? When delivering presentations I often take the opportunity to ask audiences to define airblast sprayer calibration. Their responses cover a wide range of activities that […]

This article was co-written with Mike Cowbrough, OMAFRA Weed Management Specialist – Field Crops The time and attention spent during sprayer loading is a worthy investment. It ensures that the products in the tank perform as intended and reduces the chance of physical incompatibilities. The label Pesticide labels are always the first point of reference. […]
Sprayer math is important. It ensures the operator applies the correct product rate and has enough to complete the job. But, it assumes the airblast sprayer is behaving as expected… and it often doesn’t. After confirming the airblast travel speed, use one of the following methods to assess sprayer output. There are pros and cons […]

We discuss what sets the European sprayer designs apart, with examples of overall dimensions, engine and wheel sizes, as well as tanks, booms, plumbing features. European sprayers offer similar or greater capacity compared to North American models with lighter weights and innovative designs. […]
