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 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




In susceptible weeds, Alligare Fluridone Liquid inhibits carotene production. Without carotene, chlorophyll is rapidly destroyed by sunlight. Without chlorophyll weeds die.

Initial results show a bleaching at 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 Alligare Fluridone Liquid in spring and summer during the early stage 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 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 Alligare Fluridone Liquid needs to be maintained in water for up to 45 days following application. Due to water flow will reduce. 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 Alligare 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 Alligare Fluridone Liquid into 3 equal portions. Apply each portion separately at 10 to 15-day intervals. 

Water treated with Alligare Fluridone Liquid should not be used for irrigation for 30 days following treatment.
