The Department of Agriculture, Food and Rural Development is the regulatory authority for approving plant protection products for use in Ireland.
I understand from Coillte Teoranta that plant protection products containing lindane were replaced by plant protection products containing permaset from 1 January 1999. Residual stocks of products containing lindane were largely used up during 1999 and such products have not been used since then. Any remaining stocks are being disposed of in accordance with the governing regulations.
