Effect of atmospheric turbulence on windborne drift of aerial forest sprays

, : Effect of atmospheric turbulence on windborne drift of aerial forest sprays. Proceedings: Symposium on the future role of aviation in agriculture: 427-444

Five aerial spray trials over a spruce/pine forest in New Brunswick in 1983 are described in terms of the effect of atmospheric turbulence on windborne droplet drift from ULV applications of a simulated formulation with physical properties as close as possible to those of an aqueous fenitrothion formulation.
