Elanco, in collaboration with NADIS, has once again launched the blowfly risk alert (see https://alerts.nadis.org.uk) and blowfly tracker (www.farmanimalhealth.co.uk/tracker) to help farmers and prescribers keep up-to-date and stay aware of the blowfly challenge throughout the season.

Elanco said it encourages farmers and prescribers to report a case of strike on the blowfly tracker to help others be aware of the risk in their local area and across the country.

Matt Colston, Elanco’s technical consultant, said: “From the Met Office temperature chart for February, we can see that large parts of the country have been hitting 8-10 degrees Celsius already, especially in the south.

“Correct application of an insect growth regulator (IGR) product BEFORE strike happens, is still the ‘gold standard’ in blowfly prevention.”
