Downwind Drift from Grape Airblast Spray Applications: Field Evaluation to Support Mechanistic Model Development

Supplemental Figure 1   Views of the field set-up, showing installed horizontal sampling structures and vertical string sampling structures.

Supplemental Figure 2   Built sampling structures for different sampler combinations. A) Holds flat card, artificial foliage, and horizontal string; B) holds flat card and artificial foliage; C) holds flat card or artificial foliage.

Supplemental Figure 3  Temporal variation of meteorological variables during spray experiments.

Supplemental Figure 4   Compass roses of all wind speeds and directions at various sensor heights above ground level (AGL) at the Met 2 meteorological station measured during the spray experiment.

Supplemental Figure 5   Compass roses of all wind speeds and directions during treatment test runs at the Met 1 (A; 2 m sensor height above ground level [AGL]) and Met 2 (B; 1.8 m sensor height AGL) meteorological stations.
