Adjust quantity of material up or down depending on average
depth. At a 6 ft. average depth use 50% more per 1,000 sq. ft. When
treating an entire pond you can use 25% to 50% less material and
still achieve excellent control. To apply AQUATHOL Super K
Granular, simply broadcast the granules uniformly over the water
surface by hand or use a mechanical spreader. Heavy infestations
should be treated in sections 5 to 7 days apart to avoid oxygen
*Consult Label for Exact Doses & Important Application
For best results, Aquathol Super K should be applied
as early as possible after weeds appear or when they are actively
growing. 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.
Begin application in spring as water temperature warms to 50º F
and above. Early treatment when growth first appears or begins to
create a nuisance will reduce the amount of Aquathol
Super K needed. Early treatment will also reduce the
amount of dead plant material which should be removed or left to
naturally decompose allowing the nutrients within the dead plant
material to be released into the water column.
Heavy, out of control growth may require more than one
application or physical removal to gain control. For best results,
use under conditions of minimal water flow.
Do not use in water containing
Koi or hybrid Goldfish.
