Does anyone know if aminopyralid contamination in compost/well rotted manure does affect blueberries?

[Fleecewife]

All I could find was a listing in a banned article (presumably American and not allowed in EU countries) which mentioned damage to blueberries but I couldn't read the article of course to find the details.  There are articles about persistant chemical contamination of composts damaging blueberries, but they don't specifically mention aminopyralid.


Were it me, I would err on the side of caution:  spread your manure exposed to the air somewhere for six months, which is supposed to give the chemical time to break down, then use it on non-susceptible crops.  Crops most affected are things like tomatoes, potatoes and various beans

I would like to, but they are in pots and need re-potting (or moving to an outside bed) urgently. I can probably just about justify bying some Dalefoot compost to keep them in their pots over-winter and the re-pot again next summer, but it is mot ideal, as these really would need to go outside - and I do not have a space that was left empty over summer.... anyway, still trying to work something out... I may just have to bite the bullet and see - my tomatoes were badly affected, and are now producing finally some nice tomatoes, so I know the plants do overcome the aminopyralid.
