"Cyanazine and metolachlor are important selective herbicides used for the control ofseveral annual grassy weeds and certain broad-leaf weeds in fields of corn, soybeans, and triazine-resistant canola. They are two of the 10 most heavily used agricultural herbicides in Ontario. An estimated 4.2 x 103 rnetric tons of agricultural herbicides (active ingredients) of all types were used in Ontario in 1993. More than 46% of this total was cyanazine and metolachlor. Both herbicides have been detected in river waters and well waters in Ontario. In order to make an assessment of the hazards of cyanazine and metolachlor use to aquatic ecosystems, more information is required on their persistence and fate. There is virtually no information.in the open literature on the interactions between bacterial biomass and cyanazine. work research needs identified by the Ecosystem Interpretation Branch in the development of "Canadian Water Quality Guidelines for cyanazine, and by the US.
