Fig. 7. Particle-phase loads of esfenvalerate in runoff following the application of Asana XL (a.i. esfenvalerate, 0.44 g per 162 m² plot). Asterisks represent a significant difference (p = 0.01) in pesticide load between mulch treatments for that runoff event. Numbers in parentheses represent days between application and runoff. Error bars represent the standard deviation of the means. BQL = below quantification limits.
