Fig. 4. Concentrations (±SE) of azinphos-methyl in tributary water 10 m downwind of the sprayed plot. A, calculated peak concentrations based on 95th-percentile values for basic drift deposition (Ganzelmeier et al., 1995); B1, calculated peak value based on measured deposition rate; B2, measured peak value; C, measured 1-h average value.
