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

Fig. 2. Mortality of P. dissotocum zoospores following exposure to chlorine treatments prepared with municipal water in which the pH was not lowered. Each column represents the mean (with standard error bar) of 3 experiments. The pH and ORP values at the bottom of the graph are the means and standard errors associated with each chlorine concentration.
