herbicide

what is the name of the herbicide that was passing through the animals and affecting toms and spuds?

thanks ice.
anybody had it in a shop bought compost or grow bag?

There is another herbicide called Clopyralid that has apparently turned up in compost and growbags. It has been usually in bags that are claimed to be organic or peat free.

Clopyralid was also reported by Gardening Which, to have been in B&Q organic liquid tomato feed last year. While it was then removed from their shelves, I have heard of cases where gardeners were still using it this year with disastrous results, not having heard of the potential problem.

I bought a growbag and 3 bags of compost both by Evergreen.
I always have toms on allotment and 4 more at home in 2 large pots so that the other half can pick at when passing by.
The ones on plot appear to be fine.
Those in pots were fine until planted in large pots with a mixture of grow bag and compost.
The top leaves are all twisted and narrow.
I will have to sow some more in the suspect compost to test or just throw the lot away.

I note that the ones with the problem are planted in a mixture of grow bag and your own compost. Did you treat your lawn and add the clippings to the compost? Some lawn treatments contain clopyralid, a hormonal weedkiller.
