November 26, 2002 - European Commission: Thiazafluron is one of 320 pesticides to be withdrawn in July 2003. "Some 320 substances used in plant protection products (PPPs) including insecticides, fungicides and herbicides are to be withdrawn from the market by 25 July 2003 as part of the European Commission's new approach to the evaluation of active substances in plant protection products. This aims to improve safeguards to ensure that all such products in use are safe for the environment and human health. Users, wholesalers and retailers of plant protection products will need to be aware of whether the products they use or sell are likely to be withdrawn, so as to prevent them being left with stocks of unusable material. Those concerned should contact their national authority to check the authorisation status for any particular product. The Regulation (n 2076/2002 of 20 November 2002), with the list of the 320 substances, has now been published in the Offical Journal. Ref: MIDDAY EXPRESS. News from the Press and Communication Service's midday briefing.
