Monitoring Mortality of <i>Pythium</i> Zoospores in Chlorinated Water Using Oxidation Reduction Potential

Fig. 5. Relationship of P. dissotocum zoospore mortality to ORP in chlorine treatments prepared in municipal water in which the initial pH was not lowered (red) and chlorine treatments in municipal water in which the initial pH was lowered to pH 6.0 (black). Data points represent values from all chlorine concentrations and exposure times for three experiments. Numerals indicate total number of observations represented by each data point. Slopes (b) of the two regression equations are not significantly (P < 0.05) different.
