When and How to Apply

  • Apply during sunny, dry, non-windy conditions.
  • Apply when weeds are actively growing. Best results typically achieved by starting applications just as weeds have started to grow.
  • Apply Sonar RTU directly into the water either in one location or multiple locations and Sonar RTU will mix throughout the pond.
  • Sonar RTU should be used with Captain Liquid Copper Algaecide if algae infestation is present at time of application.
  • Sonar RTU should be applied according to the schedule below, with the initial application followed by two additional applications at three-week intervals. Table 1 should be used for general aquatic weed control. Table 2 should be used for the additional benefit of partial control of watermeal. (See label for application rates table)
  • For ponds with average depth and size different than found in Table 1 (see label), utilize the following formulas and round the calculated result up to the nearest one-half (1/2) quart.

Initial Application (Day 1): Pond Acres x Pond Average Depth (in feet) = Number of Sonar RTU Quarts to Apply

Example: 0.6 Acre Pond x 3.0 Foot Average Depth = 1.8 which is rounded up to 2.0 Quarts Sonar RTU to be applied.

2nd (Day 21) and 3rd (Day 42) Applications: Pond Acres x Pond Average Depth (in feet) x 0.5 =Number of Sonar RTU Quarts to Apply

Example: 0.6 Acre Pond x 3.0 Foot Average Depth x 0.5 = 0.9 which is rounded up to 1.0 Quart Sonar RTU to be applied.

  • DO NOT apply more than a total of 3 quarts Sonar RTU per acre foot in a single growing season.

NOTE: An acre foot of water = 1 surface acre of water with an average depth of1 foot. (Example, a 1 acre pond with average water depth of 4 feet would contain 4 acre-feet of water)

Q
This past summer watermeal has invaded my pond. It is in the woods. Need advice of what to do this spring.

I have a 1/2 acre spring feed pond, 50+yrs old, with bass, blue gill, other fish also. Thanks.

A

Penn State actually has a great article on this weed that you can find here with advice on preventing it.  SePRO Sonar RTU Aquatic Weed Herbicide would be good to use on watermeal itself.
