The Onondaga County Health Department announced today that due to weather conditions this week the herbicide application to reduce the number of water chestnuts in the Seneca River will be extended into next week. The application will continue, weather permitting, on Monday, August 24th and may extend through the end of the week. We will continue to update the public if there are any further delays.

The primary herbicide that will be used for this purpose is Clearcast (active ingredient: imazamox). Rodeo (active ingredient:  glyphosate) will also be used. Clearcast and Rodeo are considered safe for the control of vegetation in and around natural bodies of water and non-cropland sites. However, Clearcast and Rodeo are harmful if absorbed through the skin or inhaled and can cause moderate eye irritation.  As a precautionary measure, we are asking the public to avoid breathing in the spray mist while treatment is being done. Signs will be posted to identify the treated areas.
