ABSTRACT

Potter, H.S. 1977. Drift control. Agrichemical Age 20(5): 20-21.

Drift can be a limiting factor in low-volume applications of fungicides. The problem lies in the high percentage of very fine drops that result with low-volume applications. The major factors affecting drop size are spray pressure, size of nozzle orifice, and orientation of the nozzle in the airstream. Spray additives such as foams and thickeners have been used with some success to control drop size.
