There has been a great deal of talk about AP.  But what is the affect of Clopyralid.  Seems it is available as Grazon 90.  What happens to the manure from this product?

It this the one that affects brassicas as well?

Clopyralid has a similar effect as Aminopyralid, but may not take quite as long to break down. Have a google for scientific papers.
