It sounds to me as if there are problems with manure containing
contaminated straw.
In the 60's we had quite a lot of dammage in the form of distorted
growth on certain species of plants including Tomatoes.
This was caused by a residue of the selective herbicide used on the
cerial crop that the straw came from.
It sounds as if this is again rearing its head.
If you have plants showing signs I would be tempted to phone Defra on
08459 33 55 77, they may be interested, on the other
hand .....................................
