Fig. 3. Dissolved- and particle-phase loads of chlorothalonil in runoff following the application of Bravo 720 (a.i. chlorothalonil, 30.81 g per 162 m2 plot). Asterisk(s) represent a significant difference (* for p = 0.05, ** for 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.
