Project Summary and Location:
DNR has applied to DEC for a permit to apply pesticides to invasive elodea growing in Chena Slough, Piledriver Slough, and Manley Hot Springs Slough in and around Fairbanks, Alaska.
 
The proposed pesticides are;
• Sonar Genesis, with EPA registration number 67690-54, with active ingredient fluridone, which will be applied via continuous drip or diluted subsurface application with weighted hoses from a boat, and
• SonarOne, with EPA registration number 67690-45, with active ingredient fluridone, which will be applied via a pellet spreader from a boat.
 
Treatment would occur between June and September throughout the duration of the permit.
 
Project Need: 
Elodea is an invasive aquatic plant that has the potential to grow abundantly and compromise water quality, hinder boat and float plane traffic, reduce dissolved oxygen, and impact fisheries. Control of this invasive plant will help prevent spread to other locations, particularly in flowing water such as these sloughs. Physical or mechanical controls are inappropriate, as these methods break the plant into fragments which can then reproduce..
