Spraying Large Nut Trees – Part 1

Introduction I’ve studied spray applications in a diversity of crops, both broad acre and specialty, but perhaps nothing is as challenging large tree nut canopies. Australia’s macadamia orchards can form >10 metre high, >4 metre deep canopy walls! So in writing this article I face the opposite situation I normally encounter when advising on airblast […]

Tower Power

Are you considering shelling out for a tower extension for your airblast sprayer? Spray towers are an excellent investment, but they warrant special consideration. Towers move the air and nozzles closer to the target compared to the curved booms on a conventional airblast sprayer. When the distance-to-target is reduced, the odds of droplets reaching the […]

Dual Fan Nozzles in Broadleaf Crops

The location of water-sensitive papers in the potato plant canopy. Two plants were papered for each nozzle.

Wondering which (if any) dual fan nozzle to buy? Symmetrical? Alternating floods? Asymmetrical? Well, first, understand they are intended for vertical targets, like wheat heads.Here’s a diagram of how they are (ideally) supposed to work: Here’s our very own @Nozzle_Guy, Dr. Tom Wolf to tell you all about them. Now understand they don’t seem improve […]

Sprayer Turn Compensation

Turn compensation is a feature in pulse width modulation (PWM) sprayers in which nozzle output matches the boom’s speed during a turn. When turning, the inside and outside of a boom travel at different speeds, resulting in over-dosing on the inside and under-dosing on the outside. Read about PWM systems here, here, and here. The […]
