Fig. 5. Dissolved- and particle-phase loads of ß-endosulfan in runoff following the application of Thiodan 50 WP (a.i. endosulfan, 9.08 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.
