Blowfly control options: There has been an increase in the incidence of blowfly strike reported this week. Farmers looking to purchase products for treating strikes are faced with fewer control options. Osmonds ceasing trading has removed Osmonds Goldfleece and Osmonds Ecofleece from the market, while Cyperguard – manufactured by Bimeda – will also be unavailable for the 2019 season.

The available dipping products are Bimeda’s Ectoflits (3l) and Hygeia’s summer and winter dip (2.27l and 4.54l ). The three of these options are organophosphate-based. Some farmers have enquired about non-organophosphate-based options, with Cyperguard temporarily unavailable.
