Restore Liquid Herbicide Application Recommendations

Published by Jamie Markoe on November 14, 2013 0 Comments

A customer recently contacted us regarding applying Restore Liquid to his pond. Below is his question and our response.


Hi-I buy my Restore from you guys every year and have an application question.  I know I’m supposed to wait until my pond reaches a certain temperature before application, but when I do this, Duckweed and Watermeal tend to get out of control.  The pond I treat is relatively shallow (average 1.5 feet and about ¾ an acre) and mucky with some floating bog on it.  How early can I apply my Restore?  Since I had trouble keeping the Watermeal under control, I’m thinking I should use a higher concentration.  Any words of wisdom so I’ll know how much to buy for this season?


Your ¾ acre pond with an average 1.5 foot depth is 32,670 sq. ft. or 1.125 acre-feet.  A pond this size would require 9 oz. of Restore Liquid.  As you may already know, Duckweed and Watermeal are both difficult to control.  Water temperature is not crucial, treatment early is.  For best results, apply Restore Liquid at the first sign of new growth when the small bright green grains begin to collect around the edge of your pond.

No need to apply a higher dose, but do break the total amount recommended into 3 separate treatments to extend the length of time solution is in the pond. 

Mix 3 oz. of Restore Liquid with enough water to spray evenly over the water surface.  Wait 14 days, mix a second 3 oz. of Restore Liquid with enough water to spray over water surface.  Finally, after another 14 days, mix the last 3 oz. of Restore Liquid with enough water to spray the water surface.  The solution will blend throughout the entire pond, stay in the pond at the required concentration and be absorbed by the small particles of Duckweed and Watermeal as they multiply.  Particles will begin to lighten in color and often pick up a pinkish hue.  Full control may take up to 90 days.

AquaClear Pellets are a second option to consider.  AquaClear will not directly kill Duckweed or Watermeal but will strip nutrients from the pond that both Duckweed and Watermeal thrive on.  By reducing the nutrient level the amount of new growth should be significantly reduced.  Your ¾ acre pond would require 7.5 lbs. of AquaClear Pellets per treatment.  A 50 lb. bag of AquaClear Pellets will treat your entire pond 6.5 times.  Treat weekly for a minimum of 4 weeks or until the desired water quality is achieved.  Sprinkle pellets directly onto the floating bog to also speed its decay.

AquaClear Pellets may negatively affect any herbicides you may be using.  If you use Restore, wait three weeks after the final treatment prior to switching over to the AquaClear Pellets for the "muck".
