Fig. 6. Amounts of (A) bromide, (B) bentazon, and (C) imidacloprid recovered from soil and the crop as a function of time as measured at the experimental field. Points are the averages and bars are the standard errors. Closed symbols are amounts recovered from the top 120 cm of soil and open symbols are amounts recovered from the crop (only for bromide). Time zero is 0000 h on 7 Apr. 1998. Note that the vertical axis of (B) is logarithmic and that imidacloprid was applied on Day 50. The arrow in (B) indicates that the point is an upper limit.
