Fig. 3. Spray deposition rates of azinphos-methyl measured in the present study and 95th-percentile values for basic drift deposition according either to the German exposure assessment procedure (Federal Biological Research Centre for Agriculture and Forestry; BBA) (Ganzelmeier et al., 1995) using late growth stage or to the U.S. Spray Drift Task Force (SDTF) data set (USEPA, 1999) using high drift potential orchards.
