The “tweet first, think later” mentality often adds to misinformation, and worse, it can leave science […]
This article continues from Part 1. Droplet size Droplet size influences droplet behaviour. The following table lists the pros and cons to changing droplet size when overall spray volume (e.g. L/ha) remains constant. Relative Spray Quality Pros Cons Coarser Droplets Lower drift potential because they resist deflection by wind and evaporation from heat and low […]
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 […]
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 […]
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 […]
