| Sumario: | A panel with dehumidifiers attachable to conventional sprayers was designed,
capable of retaining the spray liquid that is lost by drift. The objectives of this study
were: a) verify the recovery capacity of the panel, b) to study their influence on the
characteristics of spraying, c) check the drift modification in soil and the surrounding
rows. The prototype was tested in a vertical shoot positioned (VSP) trellised vineyard
cv. Malbec. The application of copper oxychloride with conventional hydropneumatic
equipment was defined as a control treatment. Spray quality was assessed using water
sensitive papers and receptors on the treated row, in two adjacent rows and soil. In field
trials, the panel recovers 37% of the volume applied for early vegetative development
and 11% with maximum vegetation. The panel did not influence the amount of product
deposited, nor the quality of the spray distribution on the treated canopy. In the conventional
treatment it was found that drift is lost mainly in the soil adjacent to the treated
rows. The panel significantly reduced drift to the soil, both the deposit of pesticide
applied as the quantity of surface impacts. |
