Fugitive Dust During Planting of Canola with an Air Seeder as a Source of Environmental Contamination for Pesticides Applied on Seed: A Case Study.

Abstract：

:The dispersion of clothianidin from treated seeds was studied in a commercial winter canola field. During planting, using a John Deere 1890 single disk air seeder, a proportion, an estimated 14.2 ± 2.9% (mean ± standard error), of the clothianidin that was applied to the seed escaped into the atmosphere from the seeder's exhaust. We suggest that this source of environmental contamination may be the main contributor that explains the off-target detection of neonicotinoid residues in soils and water near canola plantings better than movement from seed after it is placed in the soil, which is often proposed in the literature.
