I do believe that Mr Corbett missed this bit out of his report on the toxicity of fipronil. Fipronil is a highly effective, broad spectrum insecticide with potential value for control of a wide range of crop, public hygiene, amenity and veterinary pests. It can generally be applied at low to very low dose rates to achieve effective pest control. The url is: http://www.pan-uk.org/pestnews/actives/fipronil.htm for anyone who is interested enough to read the report. BTW could I clear up one point I did not say Frontline drops - but two drops of Frontline and I have clarified that is was the spray and not the Spot-on. [Posted in FML issue 4389]
