Spray drift in viticulture: A dataset to analyse the influence of spray application techniques, hedges and their combination on the reduction of sedimentary drift, aerial drift and exposure of bystanders

In 2021 and 2022, the national and cross-sector project CAPRIV funded by the French Ministry of Agriculture, made it possible to assess the influence of application techniques associated or not with a hedge or an anti-drift net on spray drift and bystander exposure. The acronym CAPRIV stands for ''Concilier l'application des PPP et la protection des riverains'' (Reconciling the use of PPPs and the protection of residents), within the orchard, viticulture, and field crops sectors. This specific data article focuses on viticulture. In viticulture, over the two years, 10 different spray application techniques were tested. For 3 of them the influence of a hedge on drift mitigation was also evaluated. All the trials were conducted on the “EoleDrift” test bench, with an artificial vegetation and an artificial wind. Spray drift has been measured according to a common protocol harmonised between cropping sectors within the project using three different types of passive drift collectors that were set up downwind of the treated field. Petri dishes collected sedimentary drift, PVC wires collected airborne drift and cotton T-shirts placed on manikins were used to assess potential dermal exposure of bystanders. The plant protection mix was simulated by a dilution of a fluorescent dye in water. The collected mass of dye was measured using a classical technique with dilution and concentration evaluation. Two fluorescent dyes were successively used, Brillant Sulfaflavine and Sulforhodamine B. A total amount of 4770 collectors were analysed individually. The data set provides a drift index for each collector expressed as the quantity of dye recovered per unit area of collector on the quantity of dye applied per unit area on the sprayed field multiplied by 100.
