Control of roundworms and tapeworm concurrently.

WHY CHOOSE FIRST DRENCH?

  • Contains levamisole

    Levamisole is a short acting clear drench. Levamisole is still highly effective against barber’s pole worm and Nematodirus on most properties. Nematodirus is often a problem after drought or in lambing paddocks as the egg is resilient and can survive in hot, dry conditions for long periods.

  • Contains praziquantel

    FIRST DRENCH contains praziquantel, the only chemical that controls both segments and heads of tapeworm. It makes sense to remove tapeworms to reduce the overall worm burden of your lambs, giving them the best opportunity to achieve peak performance.

  • Broad spectrum worm control

    FIRST DRENCH is highly effective against levamisole sensitive gastrointestinal roundworms and lungworm. It also provides control of tapeworms (heads and segments).

  • Effect against barber’s pole worm

    Where levamisole is still effective against barber’s pole worm, clear drenches provide a cost-effective, short acting option to treat this worm. This is especially important if barber’s pole worm is the major worm on a property and an alternative to a macrocyclic lactone (ML) drench is required for the purpose of rotation.

  • Ideal for lambs

    For a young lamb, life is a risky business. They’re vulnerable to cold, predators and worms. As soon as lambs start to eat pasture, they are developing a worm burden. Unlike older sheep, lambs haven’t yet built up their immunity against worms. Worm infections lead to reduced wool production and lower bodyweights in sheep of any age; a high worm burden will have a far bigger impact on young sheep.

  • Short meat WHP and ESI

    Only approximately 0.9% of the initial dose of levamisole can be found in the tissues. This enables FIRST DRENCH to have a very short meat withholding period and export slaughter interval, giving you the flexibility to get your lambs to market at the optimal time.
