Spray Mix Adjuvants for Spray Drift Mitigation
Numerous drift reduction adjuvants and spray deposition aids are available to applicators of crop production and protection chemicals. Performance of many of the newly introduced drift control adjuvants has not been well documented for aerial application. Since there are no product labeling or efficacy regulations for these adjuvants, applicators must rely on experience or information in the te...
متن کاملReducing Spray Drift
Spray drift is the movement of a pesticide through the air, during or after application, to a site other than the intended target. Drift is considered to be the most challenging problem facing applicators and pesticide manufacturers. Although drift may occur as vaporized active pesticide from the application site, it is usually the physical movement of very small drops from the target area at t...
متن کاملEvaluation and Mitigation of Spray Drift
Definition of Drift When liquids are forced under pressure through small orifices (like sprayer nozzles) they are sheared into small aerosols or particles having nearly a thousand fold range in spherical diameters. Owing to gravitational forces and the viscosity of air, the rate of fall to ground can be predicted by Stokes Law and is proportional to the radius of the particles. The rate of fall...
متن کاملResponse of spray drift from aerial applications at a forest edge to atmospheric stability
A biological pesticide was aerially applied to a hardwood forest – corn field edge in a replicated series of single spray swaths. The drift of small droplets, which remained suspended in the air after each spray swath, was monitored remotely and mapped with the University of Connecticut portable, elastic-backscatter lidar. Plumes of small droplets were tracked which drifted off after every spra...
متن کاملPropeller Wash Effects on Spray Drift
For aerial spray application, there is some question if off-target drift (both near and far) is influenced by which boom is spraying and the direction of propeller wash rotation. This information may be useful when switching off one boom close to a field boundary. The effect of alternate boom switching and propeller wash direction on aerial spray drift from a turbine-powered aircraft was invest...
