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

Fig. 4. Mortality of P. dissotocum zoospores following exposure to chlorine treatments prepared with municipal water in which the initial pH was lowered to pH 6.0 prior to addition of sodium hypochlorite. 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.
