Yes the corporations don’t want to inform us.
Wellies in this case, I would trust the manure is alright because it’s cow manure. I have not heard of cow farmers being worried by the weeds that aminopyralids kill, especially ragwort.
Plus cow farmers are not keeping animals for hobby or pleasure, but are in business and don’t want to buy expensive aminopyralid herbicides.
If unsure, do a sowing test with peas in the manure, on a windowsill.
