Seed dust emission in small grain cereals is a possible loss path for fungicidal seed dressing and furthermore a source of unrecognized release of chemicals towards non target organisms and users. In the present study, an evaluation of dust emission was conducted due to the use of different slurry solution composition (with and without adjuvant), using different application rates and crop seeds. After using a standardized treatment protocol, sample storage was conducted for an appropriate defined time until dust measurement by Heubach-dustmeter was carried out. Different levels of dust were detected according to the use of adhesive adjuvants. An overall reduction of dust level was achieved by the application of adjuvants compared to the single use of seed dressings.
