Excepting air shear and centrifugal style nozzles, most airblast sprayers employ nozzle bodies designed to except hydraulic nozzles distributed evenly along the booms. Nozzle caps compress the nozzle against the body to force the spray mix through the nozzle orifice. Nozzle bodies are not all created equal.

Continuous rinsing for airblast sprayers
Why Rinse? Airblast sprayers are not rinsed as frequently or as diligently as field sprayers. This is primarily because they are not used to spray herbicides, so residue carry-over doesn’t incur an immediately obvious penalty. The typical operator rinses prior to long-term storage or when cross contamination might cause some form of antagonism (e.g. dormant […]

For many airblast operators, the spring of 2019 has been very difficult. The frequency and duration of rain events has left limited opportunity for orchard sprays. Even then, the periods between rains are transitions between warm and moist conditions and cold fronts, which makes wind gusty and changeable. These same periods leave wet alleys prone […]
Air Orientation for Wrap-Around Sprayers
One of the pleasures of working in agricultural extension is when you’re able to help a grower solve a problem. This was one of those happy occasions. An orchardist purchased a Lipco multi-row recycling sprayer and wanted help evaluating their spray coverage. We worked in 3.7 m (12 foot), mature, high-density Royal Gala trees. The […]
Exploding Sprayer Myths (ep.10): Airblast Coverage
Here in Episode 10 of Exploding Sprayer Myths we’ve coaxed @Nozzle_Guy back into the orchard. This is part two of a two-part mini series on airblast calibration. In Episode 9 we talked about air settings and travel speed, and now we’re tackling nozzling and coverage. But here’s the twist: Rather than use spray math to […]
