Fluazuron

NGL Fine Chem Fluazuron solution is used for the control of ticks in beef cattle.

Strategic Tick Control: Specifically indicated for the cattle tick
Rhipicephalus (Boophilus) microplus
, including strains resistant to organophosphates and synthetic pyrethroids.
Preventative Treatment: It is used as a prophylactic rather than a “knock-down” treatment. Because it only affects developing ticks (larvae to nymphs, nymphs to adults), it takes approximately 3 to 4 weeks to clear an existing infestation.
Population Suppression: It has transovarial effects—treated female ticks may lay eggs, but those eggs fail to hatch or produce viable larvae, reducing future pasture contamination.
Long-Term Protection: After topical application (pour-on), fluazuron is absorbed systemically and stored in fat tissues, providing protection for 7 to 12 weeks.

Administration Method: Pour-on. The solution is applied in bands, generally in strips along the backline of the animal from the shoulder to the loins.
Dosage: The appropriate dose is determined by the animal’s body weight and the specific product instructions, with varying concentrations used in different regions.
Treatment Schedule: It is applied as a treatment per season, with the potential for subsequent applications as directed by product labeling.
Systemic Action: After topical application, it is absorbed through the skin or upon licking, enters the bloodstream, and is deposited in fatty tissues. It is then released slowly to provide long-lasting control.
Efficacy: It acts as an insect growth regulator, inhibiting chitin synthesis, which stops ticks from molting and eggs from hatching, rather than providing immediate “knock-down” of adult ticks.
