Fluridone Liquid is a systemic herbicide for controlling weeds in freshwater ponds, lakes, reservoirs, irrigation canals, and drainage ditches.
Fluridone Liquid provides excellent control of many difficult to control weeds, including Duckweed, while allowing desirable vegetation to remain.
Treat your entire pond.
For ponds, 10 acres or less in size, treat entire pond or a minimum of 5 acres.
For lakes, more than 10 acres in size, treat a minimum of 5 acres.
Treating less than 5 acres or treating narrow strips may not produce satisfactory results due to dilution.
Fluridone Liquid is absorbed by leaves and stems directly from water and by roots from hydrosoil.
In susceptible weeds, Fluridone Liquid inhibits carotene production. Without carotene, chlorophyll is rapidly destroyed by sunlight. Without chlorophyll weeds die.
Initial results show a bleaching at growing tips of the weed. Within 7 to 10 days weeds begin to turn pink then white. Growth is halted and weeds begin to die.
Results occur slowly. Under optimum conditions, full kill occurs in 30 to 90 days. Fluridone Liquid will not cause oxygen depletion resulting from rapid weed collapse.
For best results, apply Fluridone Liquid in spring and summer during the early stages of growth. Weeds are more easily controlled when treated at this time. Less material is required and results occur more quickly. Fluridone Liquid works on susceptible mature plants but will require higher application rates and more time to show the full effect of an application.
A little goes a long way.
Consistent concentrations of Fluridone Liquid needs to be maintained in water for up to 45 days following application. Rapid dilution due to water flow will reduce results. Best results occur in ponds with little or no outflow.
To apply, determine the volume of water to be treated in acre-feet. Use 1 pint of Fluridone Liquid per 2.5 acre-feet. Dilute with 5 to 100 gallons of water and apply uniformly over the surface with a Constructo Tank Sprayer.
Visible results in 7 to 10 days.
Use Sonar Q Granular when treating a portion of a large body of water. This will help maintain a consistent concentration at the treatment site by reducing dilution.
For Duckweed, split the calculated amount of Fluridone Liquid into 3 equal portions. Apply each portion separately at 10 to 15-day intervals.
Water treated with Fluridone Liquid should not be used for irrigation for 30 days following treatment.
