Talk:Ammonium sulfamate

message: This compound appears to be much more toxic than the author describes. The compound is described completely at this site: http://pmep.cce.cornell.edu/profiles/extoxnet/24d-captan/ammonium-sulfamate-ext.html. 
The lethal dose as measured in rats is comparable to that of other herbicides (2-4 gms AMS/kg body weight). It is extremely toxic to birds; the lethal dose is 2-4 micrograms/kg. It is readily soluble in water, and does not bind to soil, so it is easily transported by groundwater. Its breakdown time is several months.
Comment: the LD50 of NaCl for rats is also 3 g / Kg, but I don't consider salt an overwhelmingly toxic compound.  —Preceding unsigned comment added by 63.115.29.242 (talk) 18:22, 17 September 2008 (UTC)

This seems to explain it the 'ban'.  Sheer EC burocrasy and deprivation of general public of what seems to be a pretty good brushwood weed killer with apparently very low impact on just about everything else.  
http://extoxnet.orst.edu/pips/ammosulf.htm gives a USA perspective which supports the useful low toxicity arguement.  
Who was supposed to submit the complete dossier (data package) to whom in the EC and didn't do so?  They might have submitted the American one or perhaps the burocrats should have done their own research on it and then not withdrawn the chemical and all products containing it.  
People like me with a quarter acre of 2m high stinging nettles surrounding our caravan on a leisure plot we bought get no help from this EC action.  Other nastier options continue to be sold and used!

thread_title:  Ammonium Sulphamate withdrawal by EC on 22 Nov 2007 and use stocks by 22 May 2008 

message: This should be an article about the substance ammonium sulfamate, its properties, manufacture and applications. It is largerly a "how-to guide" describing the use of this chemical as a herbicide in a manner that is not consistent with an encyclopeadia, and advocates its safety and usefulness. While the subject of its "ban" by the EC vs. its safety, environmental friendliness and so on could be discussed more objectively (NPOV) in a "Controversy" section, as it is now, it presents a single point of vue (not necessarily bad, however, POV). This article needs a thorough rewriting.
P.S.: Any agrochemist here? Does anyone know what mechanism of herbicidal action does this substance have? Is it simply a "salt-type" herbicide, killing the weeds by its hyperosmolarity? Some kind of this information would be also useful for the article.--84.163.119.249 (talk) 01:22, 25 November 2007 (UTC)
