Establishing an optimal airblast carrier volume

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 […]

Crop-Adapted Spraying – A Multiyear Study in Highbush Blueberry (2024 Update)

This case study is taking place on a 15 acre highbush blueberry operation in southern Ontario. In 2016, considerable pressure from spotted-wing drosophila (SWD) prompted the growers to make changes to their crop management practices and their spray program. They employed a three-pronged approach to improving crop protection: We have been tracking pesticide use, water […]

Fungicides with a Custom Applicator: Drive-Along Diaries #4

In this fourth installment of the Drive-Along Diaries, we’ll shift our focus a little. I’ll continue to share observations about real world spraying practices, but we’ll also dip a toe into the business side of custom application. Every contractor’s situation is different, but perhaps you’ll be able to relate to some of these experiences. 4:30 […]

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 […]
