Spray drift of pesticides arising from aerial application in cotton

摘要

This paper presents results from field studies carried out during the 1993-1998 Australian cotton (Gossypium hirsatum) seasons to monitor off-target droplet movement of endosulfan insecticide applied to a commercial cotton crop. Averaged over a wide range of conditions, off-target deposition 500m downwind of the field boundary was approximately 2% of the field applied rate with oil based formulations and 1% with water based applications.
