Pyralid weedkillers in compost 2: amino- and clopyralid, effects and healing

Small residues of this persistent product are now present in many composts, even "organic" ones. I show how to check for their presence by growing bean and pea seedlings.
Testing like this is called a bio-assay, and is more effective than laboratory testing, partly because the amounts of active compound are so tiny. Many lab tests show as "negative", when poison is there and causing damage.

We need people to know about it!
You can heal affected compost by spreading it on soil, without tilling. Find out more in my earlier video on aminopyralid https://www.youtube.com/watch?v=w7vr-GlzuZs
