The Effect of the Air Blast Sprayer Speed on the Chemical Distribution in Vineyard

I.H. Celen, S. Arin and M.R. Durgut    

Abstract: A study was conducted to determine the spray deposition patterns for air blast sprayers used to apply chemicals to the canopy of Semillon grapevine in vineyard. The application carried out in 12 bars and three sprayer speed (2.1-4.9-7.7 km h-1). The spray deposition was measured on the point in the different distances (1.5-3-6-9 m). Tartrazine were applied as tracer material. Maximum spray deposit was obtained 66.1 mg cm-2 at sprayer speed of 2.1 km h-1 and minimum deposit was obtained 37.1 mg cm-2 at sprayer speed of 7.7 km h-1. The results showed that the sprayer speeds had significant effect on spray deposit distribution and increasing of the sprayer speed increased drift.
