Pesticide drift deposition in hedgerows from multiple spray swaths

A series of spray experiments was conducted in order to determine deposition at different heights of the hedgerow and to estimate the effect of unsprayed buffer zones on spray deposition. Deposition varied highly with distance, absolute humidity, height, droplet size distribution and wind speed. Eighty-two percent of the observed variation could be accounted for by these factors. Droplet size distribution depended on nozzle type and working...
