The Effectiveness of Riparian Hedgerows at Intercepting Drift from Aerial Pesticide Application

The primary tool used currently for preventing pesticide drift from entering streams is a no‐spray buffer zone. Riparian hedgerows may provide an additional option; however, quantitative information on their effectiveness is limited. To quantify the potential benefit of riparian hedgerows for drift reduction, aerial malathion {diethyl 2‐[(dimethoxyphosphorothioyl)sulfanyl]butanedioate} applications on blueberry ( Vaccinium corymbosum L.) farms...
