TechTour: Gearing Down on High-Speed Spraying


On-farm efficiency is certainly a hot topic in today’s agricultural climate. But are we getting a little too keen for speed in the sprayer?

We’ve heard often the importance of patience while seeding (check out the Canola School on seeding speed/depth from 2013), but sprayers are often exceeding 15mph in the field.

This can have detrimental impacts to the quality of the application, says spray application specialist, Tom Wolf.

“There are certain downsides to spraying fast. One of them is that we have more drift. Even with the same nozzles, same boom heigh, evertyhing else the same, the faster we go, the more those little tiny droplets come out of the spray pattern and then we’ve lost control of them,” says Wolf, adding that faster speeds also tend to mean greater boom height, which merely compounds the risk of drift.

There are a few different ways to mitigate the risk of drift, when spraying at high speeds, and in this episode of the Tech Tour, Shaun Haney and Tom Wolf discuss some of those better management practices. The duo also discuss productivity increases beyond the speedometer, the TechTourLIVE events coming up and…the ’80s?
