 New chemistry.
The
active ingredient in AVENGE is imidacloprid, belonging
to the class of chemical insecticides known as the neonicotinoids.
It is the first new molecule in sheep lice control for
more than five years. It acts selectively on the central
nervous system of lice for rapid control.
New solution.
AVENGE controls lice resistant to other chemical groups:
- It delivers a completely new mode-of-action for sheep
lice control, making it a vital tool for insecticide
resistance management.
- It provides uncompromising lice control while breaking
the resistance cycle.
- The introduction of imidacloprid as a first-in-class
active ingredient foreshadows a new era in sheep lice
control.
New standard.
