ABSTRACT: Bacterial populations in nontreated and herbicide‐treated waters were subjected to three different herbicides. Diuron, dichlobenil, and diquat were added (100 mg/l) to water samples from two fresh water lakes and two herbicide‐treated ponds. Total numbers of bacteria were monitored. Bacterial populations in fresh lake water decreased after herbicide additions; however, final populations were significantly greater than the controls. Similar observations were recorded for bacteria in dichlobenil‐ and diuron‐treated waters. Selective enrichment is probably expressed in these experiments.
