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 ground application. Tree drift control adjuvants were selected for drift studies in ar assisted applications. Deposition and downwind drift in a vineyard canopy were collected on Filter papers for measurement and analysis. The deposition was highly correlated to the drift distance and treatments or adjuvants. Treatment and distance had significant effects on deposition. The filter papers detected essentially no droplet depositions beyond the 24 m. All the treatments had smilar deposition values from 6th and 9th m. The results will aid applicators in selecting drift reduction agents to meet the drift mitigation criterion for a given application.
