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 […]
Managing the canopy of any perennial crop (e.g. pruning, hedging, leaf stripping, etc.) is an important consideration. The benefits are manifold: It affects the health of the plant, the quantity and the quality of the yield. It allows light and air to circulate and it keeps the crop manageable. From the perspective of an airblast […]

It’s nearing the end of a long morning of spraying and you just want to get it done.As the tank empties and you watch the last of the spray cloud waft through the row, you’re thinking about rinsing out and moving on… but did the spray land where you wanted? How do you really know […]

Most pesticides are either pre-formulated with the required adjuvants, or the label specifies their addition. However, compelling claims by manufacturers create interest in tank mixing additional adjuvants to improve some aspect of pesticide performance. In a previous article we advised caution when using adjuvants in airblast sprayers (see here). Specifically, we stated that unless an adjuvant has been tested with airblast equipment, […]

Overview This article expands on an earlier article: here. Before we dive into the details, let’s start with a quick video summary filmed by Real Agriculture at Canada’s Outdoor Farm Show in September, 2016. When the pressure drops and the nozzles begin to sputter, the sprayer is considered empty. However, it can still retain a lot […]
