Nov 26, 2002 - European Commission: Barium fluosilicate is one of 320 pesticides to be withdrawn in July 2003.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320 substances used in plant protection products (PPPs) including insecticides, fungicides and herbicides are to be withdrawn from the market by 25 July 2003 as part of the European Commission's new approach to the evaluation of active substances in plant protection products.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retailers of plant protection products will need to be aware of whether the products they use or sell are likely to be withdrawn, so as to prevent them being left with stocks of unusable material.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 been published in the Offical Journal. Ref: MIDDAY EXPRESS. News from the Press and Communication Service's midday briefing.

Explanation from PAN:
* Parent: Compounds labeled with a "P" are the parent compound of the group. The parent chemical was chosen on the basis of available toxicity information, where chemicals with the maximum amount of toxicity information assigned to parent status. Where no toxicity information was available for any member of a group, we assigned parent status to the least derivatized member of the group for organic compounds (e.g., benzoic acid would be the parent instead of methyl benzoate), the sodium salt (for compounds with a common anion), or the chloride salt (for compounds with a common cation). These are general guidelines and not hard and fast rules, because the groups are rarely so easy to categorize. For some groups with no obvious parent, assignment of parent status was arbitrary.

Group 1: Salts, esters and/or complexes of the parent chemical, e.g., glyphosate and glyphosate, isopropylamine salt; 2,4-D and 2,4-D, butoxyethyl ester. Alternatively, the parent compound itself is an ester or salt, and related compounds are other esters or salts.
