[USCC] Clopyralid

[Ron Alexander]

Hello Compost World,

I am interested in identifying researchers (or composters) who have completed research on Clopyralid damage on plants caused by the use of contaminated compost. Can any one point out people that I may speak to? I am really interested in finding out if we know ...

1. What the threshold values are for Clopyralid contamination, whereas we can still market the product for use in popular applications (e.g., nursery production/raising seedings).    AND

2. If the addition of any materials (e.g., graphite, lime, gypsum, etc.) have been tried to alleviate Clopyralid damage?

Thanks for any input.
Ron
