My English vocabulary does not include sheep dip, but I believe it is a where you treat the sheep for parasites. Concidering my own experience with sheep and the advices we got from old sheepfarmers concerning suitable chemicals I would take a careful look at the sheep dip. Perhaps a talk with an older vet could be useful. I especially remember one man who suggested us to use a a treatment against fleas that were actually made for horses. On the package it clearly stated that it was not intended for yong animals but he did not hesitate to put it on new born lambs. In this case the active compound was an organic phophorous compond, but I do not remember its name. Good luck!

A sheep dip is shown to be in close proximity to what will become the garden. The current owner of the farm has been in residence for over 40 years and in that time the sheep dip has not been used. I am however concerned about the nature of the chemicals used in sheep dips and whether they, or their breakdown products may still pose a risk to the end-users of the site? Does anyone have any experience of such sites? Can anyone provide me with guidance on the types of chemicals used and their persistence in the environment?
