Experts from The Arable Group (TAG), the UK’s leading independent crop research and consultancy organisation, are using a Spraytec droplet size analyser from Malvern Instruments in work to improve the understanding of agrochemical spray behaviour. Since droplet size influences spray drift, run-off and plant uptake, it is a key parameter in understanding the impact of pesticide use and in predicting the deposition patterns associated with different spray systems. Spraytec offers the robust operation and rapid data acquisition speeds needed for the reliable measurement of wide spray plumes and is being used to measure droplet size distributions in real-time during spraying. Spraytec measures sprays with particles in the size range 0.1 to 2000 microns. Its exceptionally fast data acquisition rate allows the real-time capture of atomisation dynamics in fine detail.
