Drench rotation
Prolonged use of the same class of drench will
quickly lead to resistance. Rotating to a different
class of drench during the year reduces the use
of just one class and delays the development of
resistance.

| “Resistance
is now at the level where we have
to use combinations of two or three
short duration drenches for all our
treatments, not just the summer drenches.” |
| Dr David
Rendell, Veterinary Consultant,

|
|
| “When you combine
two or more drenches together the
development of resistance to each
of them decreases.” |
| Dr David
Hucker, Veterinarian,

Rotate to Rametin to beat resistance
Rametin contains naphthalophos, a narrow-spectrum
drench that belongs to a unique family of drenches
that has no resistance problems despite 40 years
of use in Australia. This means Rametin can be
mixed with other drench families to form a highly
effective combination.

Rotate
between Rametin Combo and Rametin ML for maximum
efficacy and longevity.
Rametin can be mixed with any of the other drench
families – the whites, clears, white/clear combinations
and ML drenches. As Rametin is a member of a different
group of drenches it is ideal for mixing with other
drenches and for use in rotation as it kills worms
resistant to the other drench groups. Tests show
that Rametin gives >99% control of susceptible
barber’s pole worm and up to 100% broad-spectrum
worm control when used in combination with white
and clear drenches.
| Where there is any hint of ML resistance in purchased sheep, Rametin should be included as part of a powerful combination treatment. |
