Aminopyralid and chloryralid

Aminopyralid: We Need  to Stop This (No Dig Home blog, 13 June 2019)

After reading this blog post, I did some research on aminopyralid. 

The most concise and objective article I found was ChemicalWatch Factsheet Aminopyralid (Beyond Pesticides)  which recounts several incidents of manure and hay contamination which led to crop losses. 

The PANNA pesticide data base shows mostly ? for major effects, likely because the chemical has has been registered reasonably recently (2005 in the US, 2006-12 in Canada)   and there have been no independent reviews. Also note that the US registration was conditional which means that all the mandatory tests were not performed. 

A PMRA label search indicates 11 current Canadian labels. (22 August 2019). The product names include Milestone, Restore, Clearview and Reclaim.

The National Library of Medicine HSDB Database (TOXNET) also has a page on Aminopyralid  'Occupational exposure to aminopyralid may occur through inhalation and dermal contact with this compound at workplaces where aminopyralid is produced or used.'

I found very few scientific articles on google but this one was interesting:

Aminopyralid soil residues affect rotational vegetable crops in Florida 16 March 2011 (wileyonlinelibrary.com) DOI 10.1002/ps.2119 Spraying with aminopyralid of the bahiagrass used in rotation caused severe damage to following crops.

Clopyralid is apparently not registered in Canada at this time.
