Government response to aminopyralid ban
http://www.number10.gov.uk/Page21280
The petition was:- "We the undersigned petition the Prime Minister to refuse to reinstate Aminopyralid as a weed killer in Britain.” Details of Petition: “A hormone weed killer (Aminopyralid) used on grassland was taken up by grazing animals and remained in manure which, when applied to the land, caused the failure of a wide range of crops including beans, peas, potatoes and tomatoes, soft fruits and flowers. Aminopyralid attaches itself to organic matter and the length of time it takes to beak down completely is as yet unknown. The potential for contamination by aminopyralid and clopyralid is causing growers to lose confidence in peat free composts. Due to the occurrence of patches of contamination in organic matter it is extremely difficult if not impossible to ensure an uncontaminated end product. A receiver of contaminated material is landed with a problem of disposing of toxic waste. After widespread protests it was withdrawn in August 2008 but an application has been made for its reinstatement. We believe that, even taking into account improved stewardship, the use of this chemical cannot be adequately controlled.” The government response was:- "The Government acknowledges the difficulties that the use of manure containing traces of aminopyralid has caused some gardeners and allotment holders. In issuing approvals for two new products, it carefully considered the advice of the independent Advisory Committee on Pesticides (ACP). The restrictions on the new approvals are intended to ensure that manure containing aminopyralid does not leave the farm: * The new products may only be used on grassland for grazing (not for forage) or amenity grassland. * The labels must state that manure from animals grazed on grassland treated with aminopyralid should be returned directly to grassland - i.e. kept on farm. Similarly, labels will contain a warning that animal waste or plant material suspected of containing aminopyralid must not be used for composting or mulching. * Only grassland grazed by cattle and sheep may be treated - not land grazed by horses. DowAgrosciences has developed a communications and stewardship campaign for users and distributors to further reduce the risk of problems arising from manure containing aminopyralid residues. The company will also submit regular reports to Government detailing any complaints and the action taken. These complaints and any received directly will be monitored and, where appropriate, investigated by the Chemicals Regulation Directorate. If, despite these additional controls and safeguards, significant problems arise in future, the Government’s position will be reviewed again." So effectively big business wins as usual.. |

Government response to aminopyralid ban
"wafflycat" wrote The petition was:- "We the undersigned petition the Prime Minister to refuse to reinstate Aminopyralid as a weed killer in Britain.” Details of Petition: : ((Huge Snip)) So effectively big business wins as usual.. The interesting data on this weedkiller is... "Under aerobic conditions, degradation of aminopyralid in five different soils resulted in the production of CO2 and non-extractable residues. Half-lives ranged from 31.5 to 533.2 days in 5 soils. For risk assessment purposes, EPA used a half-life of 103.5 days. Aminopyralid photolyzed moderately slowly on a soil surface. The half-life was 72 days and CO2, non-extractable residues and small amounts of acidic volatiles were the degradates." So it may be around for a bit yet in some soils even if everyone keeps to the new rules. -- Regards Bob Hobden just W. of London |
