Direct comparison of deposit from aerial and ground ULV applications of malathion with AGDISP predictions

A series of field trials were completed to inter-compare ground deposition from ground and aerial sprays of Fyfanon® ULV adulticide and to compare these results with others predicted by AGDISP. A ground cold-aerosol generator (Clarke GRIZZLY) was used in wind conditions ranging from 3.6 to 12.4 kph. Deposit samples (fiberglass filters) were taken at 10 m intervals to 500 m downwind. Collocated at alternate sites, the spray cloud at 1.4 m height was characterized using rotating 3 mm rods to…
