Establishing an optimal airblast carrier volume

An orchardist taught me this trick: If you want to know if spray will penetrate a canopy, you should be able to see sunlight through the shadow at high noon.

Thanks to Mark Ledebuhr of Application Insight LLC for his contributions to this article. North American product labels may or may not include carrier volume recommendations. When they do, it could be based on a two-dimensional value like the planted area, or perhaps on row length which is more appropriate for trellised crops that form […]

Determining an ideal airblast sprayer travel speed using the “Air Displacements” method

The concept of Air Displacements was developed by Dr. David Manktelow, Applied Research and Technologies Ltd. What is the “right” speed to drive when spraying? Airblast sprayer operators must know their average travel speed to calculate how much pesticide and time is required to complete a spray job. Note that it’s an average, not a […]

Airblast Productivity and Work Rate Calculator

There are many factors that affect the work rate of an airblast application. If an operator can improve their work rate, without compromising spray efficacy or safety, they improve operational efficiency and save money. But how does each variable factor in? Is it worth the cost of a tender truck and operator to fill more […]

Airblast Nozzles – Distributing Flow

There’s a certain deer-in-headlights expression that creeps onto a sprayer operator’s face when we discuss nozzle selection. We sympathize with our field sprayer clients given the variety of brands, styles, flow rates and spray qualities they must choose from. And PWM has made the process even more complex. However, airblast operators face an additional challenge; Unlike […]
