Aquathol Super K Granular
Aquathol Super K Granular with potassium endothall is a selective, rapid­acting, contact
herbicide. Controls submersed weeds in lakes and ponds. Works rapidly enough to be
effective in both still and slow moving water.
Aquathol Super K Granular is a convenient ready­to­use granular product. Nothing to mix or
spray. Begins working on contact with submersed weeds to break down cell structure and
inhibit protein synthesis. Without this ability the weed dies.
Initial results in 1 to 3 days.
Full kill takes place in 1 to 2 weeks. As weeds die they drop to the bottom and
decompose. Effective anytime live weeds can be contacted. Best results occur when
applied in spring and summer as water temperature rises to 65 degrees Fahrenheit or warmer. With early treatment less
material is required and a longer weed free period will result. Contact time with weeds should be at least 2 hours. In large
bodies of water longer term control will result when treating a minimum of 1 acre or 100 ft. of shoreline. Although
selective, Aquathol Super K Granular is effective on many different weeds.
Excellent Pondweed control.
Recommended application rates for Aquathol Super K Granular range from 0.5 to 5.0 ppm. Safe for most fish at 100 ppm
or more. For most Pondweeds growing in lakes 2.0 to 4.0 ppm will give excellent control. This rate is equivalent to 0.8 to
1.6 lbs. of Aquathol Super K Granular per 1000 sq. ft. at an average depth of 4 feet. When treating an entire pond you
can use 25% to 50% less material and still achieve excellent control.
To determine pounds of Aquathol Super K Granular to use per 1,000 sq. ft.
(application rate in ppm) x (average depth in feet) x (0.10).
To use 3.0 ppm at an average depth of 4.0 feet:
3.0 x 4.0 x 0.1 = 1.2 pounds per 1,000 sq. ft.
Treat heavy infestations on sections of 1/3 to 1/2 of the total weed volume to avoid oxygen depletion. Allow 5 to 7 days
before continuing to untreated areas.
Water in areas treated with Aquathol Super K Granular should not be used for irrigation or human consumption for 7
days.

Long-Leafed Pond Weed
Did not buy. Not legal
Great product!
product as described, quick shipping, great price!
So far it looks like it's working as advertised. Still too soon to tell.
Did not buy. Not legal in Wa state
We have had lake weeds for years surrounding the dock. It was getting to the point that you couldn't
swim without the weeds wrapping around your legs. One application in the Spring and they are gone!
Amazing!!!
