We are still suffering the effects of Clopyralid (Persistent herbicide)

We are still suffering the effects of Clopyralid (Persistent herbicide) in our compost.  The latest problem is in our main crop peas (see picture)  I have also had trouble with my sunflower seedlings and bean seedlings in pots and in the ground. The pot problem is particularly frustrating as I was planting in pots to avoid low germination problems and inadvertently managed to use contaminated horse manure in the compost.   The Internet seems to offer only time as a healer for this problem! see this useful article;  http://www.jgpress.com/BCArticles/2001/070125.html
