One of the most challenging aspects of a spray operation is the disposal of leftovers or rinsate containing pesticides. Let’s be honest, too much of it is drained onto the ground in a corner of the yard or the field. Nobody’s happy about that, nobody’s proud of it, but what are the alternatives? Waste disposal […]
Horticultural crops cannot be produced commercially without the use of pesticides to manage the impacts of insects and pathogens. Growers recognize the importance of pollinators and in some cases, rely on bees for pollination. Growers are practicing due-diligence to try to minimize the effects of necessary pest management activities on bees. There’s a fine balance […]
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 […]
