Chemicals registered to treat lice and flystrike on sheep


NSW sheep producers spend more than $30 million per annum on chemicals to treat or prevent infestations of body lice (Bovicola ovis) and flystrike by the sheep blowfly (Lucilia cuprina).

Clearly, with this level of investment it is important that they make wise treatment choices and only use products registered for these purposes.

Product choice is likely to be influenced by price, safety to the user, effectiveness of the product and the residue consequences of treatment such as withholding period, export slaughter interval and market access.
