Advice On Use
• WSD LOW VOLUME COMBINATION is a broad-spectrum treatment which is highly effective against mature and
immature worm parasites on many Australian farms.
• The use of WSD LOW VOLUME COMBINATION or WSD COMBINATION drench is indicated in strategic programs
to reduce contamination of pastures when testing has shown it to be effective against local worm parasites.
• The simultaneous administration of a BZ and levamisole may be effective against worm parasites resistant to either
drench administered singly or against strains of Ostertagia resistant to ML drenches. It is advisable to test efficacy before
relying on combination as a strategic treatment.
• On many farms, WSD LOW VOLUME COMBINATION is an effective treatment for worm infestations due to
stomach, small and large bowel parasites. It is particularly useful to treat an infestation by mature and immature worms in
animals grazing pastures known to be moderately or heavily contaminated with worm larvae.
• WSD LOW VOLUME COMBINATION is highly effective but without residual effect against barbers pole worm
(Haemonchus) and can be used to treat haemonchosis.
• The repeated use of any drench is likely to result in the emergence of resistance in worm parasites and therefore,
regular testing for efficacy is recommended.

Advice On Use
• Abamectin is a broad-spectrum treatment which is highly effective against mature and immature worm parasites on
most Australian farms including against strains of Ostertagia resistant to ivermectin.
• The use of WSD ABAMECTIN, WSD ABAMECTIN PLUS SELENIUM or WSD LOW VOLUME ABAMECTIN is
particularly indicated in strategic programs to reduce contamination of pastures when the uptake of worm larvae is low.
• Consider using other WSD drenches, particularly WSD COMBINATION, if the objective is to treat a worm infestation
on pastures known to be moderately or heavily contaminated with worm larvae.
• Abamectin is NOT effective against tapeworms.
• The repeated use of any ML drench is likely to result in the emergence of resistance in worm parasites and therefore,
regular testing for efficacy is recommended.
