An experiment was conducted during the fall of 1983, in a conifer plantation near Thessalon, Ontario, to assess the downwind deposits and airborne concentrations of permethrin [3-phenoxybenzyl (±) cis-, trans- 3-(2,2-dichloroviny1)-2,2-dimethylcyclopropanecar-boxylate], following application as an emulsion formulation, over a single 100 m spray line at 35 g AI (active ingredient)/ha. The insecticide was collected up to 150 m downwind by using various static collectors and air samplers. Simultaneous measurements of droplet deposition on Kromekote® cards permitted calculation of droplets/cm2 and size spectra. The data indicated that permethrin deposits on all static collectors were greatest within 30 m of the spray swath. Deposits per unit area of the collectors, droplets/cm2 of the sampling cards and airborne concentrations all decreased exponentially with increasing downwind distance. Beyond 30 m downwind, the amounts of the insecticide trapped by various collectors were extremely low, and were barely detectable. |
