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