ARGOS - ARGOS is a liquid chelated copper that targets algae.  Treatments will start at approximately 7:00 am each day, and take 6 hours at each application site.  It is applied at the rate of 1 ppm for a 6-hour set; this compares to the Copper Sulfate Crystals, which are applied at a rate of 5-6 ppm and have a lengthy holding time.  Treatments are done over 2-3 days due to the lengthy application time.

ACROLEIN (MAGNACIDE H) - Magnacide H (active ingredient Acrolein) targets pond weed and algae.  Treatments will start at approximately 6 am. 

Any changes from this schedule will be updated here as soon as they are known.  If you have any questions, please call the office at 541-922-3814.
