AB The optimization of the water volume used to apply pesticides with airblast sprayers is keyto reducing water footprint, costs, operational time and drift of pesticides. This study evaluated anew tool (CitrusVol) that adjusts the spray volume to the characteristics of the vegetation and thepesticide used to control the two-spotted spider mite Tetranychus urticae in clementine trees. Thismite is one of the main citrus pests because it damages fruit before harvest. For this aim, a total of20 applications against T. urticae were evaluated during two consecutive years in seven commercialorchards. In these orchards, we evaluated: (i) the distribution of the spray in tree canopies, (ii) pestdensity before and after the treatment, and (iii) fruit damage at harvest when conventional volumesand volumes adjusted with CitrusVol were applied. On average, CitrusVol reduced 36% the watervolume used to control T. urticae in the 20 applications. This reduction in the spray volume involveda decrease in the coverage in some parts of the canopy. However, T. urticae density and fruit damageat harvest were similar in trees treated with the adjusted volume calculated with CitrusVol and thevolume used by the owners of the orchard. Therefore, the spray volume recommended by CitrusVolis adequate to control T. urticae in clementines.
