Although FAO specifies a particular range of droplet sizes for desert locust control-VMD should be between 50 and 100 μm; this is a huge range (eight-fold) of droplet volumes. This study was used to other specialist facilities at IPARC (low speed wind tunnel, spinning top droplet generator and image analyser) to try to refine these recommendations to a narrower range of desirable droplet sizes. One of the objectives of this study was to obtain data that might suggest changes in operational parameters, which could lead to the minimization of the off-target drift that primarily arises from the small droplets produced during atomization. The analysis of data has revealed some interesting trends that were not otherwise apparent. Grouping the data from several experiments has helped to increase the reliability of the results.
