Advice On Use Cattle: •
WSD LEVAMISOLE is a reliable broad-spectrum oral drench for cattle of all ages. • It is often best administered to adult cattle with a drenching hook. Sheep: • WSD LEVAMISOLE is a broad-spectrum treatment which is highly effective against mature and immature worms of susceptible strains of sheep parasites. • It is highly effective against and can be used to treat infestations by barbers pole worm (Haemonchus contortus) and thin-necked intestinal worm (Nematodirus spp). • The use of WSD Levamisole may be indicated in strategic programs to reduce contamination of pastures when testing has shown it to be effective against other local worm parasites. It is advisable to test efficacy before relying on levamisole as a strategic treatment. • Adult worms of resistant strains of gastrointestinal worm parasites of sheep may not be removed by treatment and this may require the later use of an effective strategic treatment from the WSD range of drenches. • Levamisole is not effective against tapeworms. • Resistance to levamisole is widespread among some species of gastrointestinal parasites on Australian sheep farms. • The repeated use of any drench is likely to result in the emergence of resistance and therefore, regular testing for efficacy is recommended.
