Once applied, fluridone is absorbed by shoots and roots where it travels systemically in the internal vascular system of aquatic weeds. fluridone inhibits carotene synthesis causing chlorophyll to break down when the weeds are exposed to sunlight. New shoot growth will exhibit a pink or white coloration within 7-10 days of exposure to fluridone with long lasting capabilities making fluridone with Fluridone the herbicide of choice by many aquatic maintenance professionals.

For complete weed control, contact with fluridone must be maintained for an extended period of time depending on the severity of the infestation. Also, if conditions exist that dilute the fluridone concentration in the water, effective control may not be achieved and additional application may be necessary.
