Animal ear-tags, their manufacture and their use
Abstract
Abstract The invention relates to animal ear tags. Ear tags for attachment to ears of animals such as cattle in accordance with the invention are made at least in part from a material comprising a solid organic polymeric macromolecular substance having a molecular weight above 1000 and a pesticidally-active compound having the general formula: <IMAGE> (I) wherein R1 and R2 are independently selected from fluorine, chlorine and bromine; X is hydrogen, cyano or ethynyl; and Z is hydrogen, chlorine, fluorine or bromine. The invention also provides a method for making the tags by mixing the macromolecular substance and the compound of formula I and forming the tag by injection moulding, and further provides a method of controlling fly and tick populations in the vicinity of an animal by affixing to an ear of the animal a tag in accordance with the invention. The ear tags are surprisingly effective in the control of insects and ticks on animals, such as cattle.
