Aminopyralid poisoning?

We have been cultivating the Annecy Gardens organically & as I have mentioned previously, the Council have kindly provided us with manure. However, some plants are showing significant distortion & we are fearful that the manure, although well-rotted, may be contaminated with aminopyralid. This is a herbicide used to control broadleaf weeds in pastures. Unfortunately it appears to be remarkably persistent ~ when grass that has been treated with aminopyralid is turned into hay & then subsequently composted after being fed to livestock or used as bedding, the aminopyralid appears to remain active & can affect crops to which the manure is applied.

Here are photos of plants at the Annecy Gardens which have distorted leaves.

We have only had manure on a relatively small part of the Gardens, so hope that relatively few plants will be harmed.

Other sunflowers are growing very well, some must have grown 6" since last week and the climbing french beans are making rapid progress up the hazel wigwams.

The 'Sharpe's Express' potatoes, shown as very sprouty seed potatoes at the beginning of May are looking very well, just producing flowers. Generally, it should be about 10 weeks from planting first early potatoes to harvesting them, so still a few weeks to go.

The artichokes are looking magnificent & the first heads have already been harvested.

Also ready for harvest are gooseberries, the plants producing a crop despite only being transplanted to the Annecy Gardens in February.
Gooseberry, variety unknown but probably 'Leveller'
The lettuce 'Lollo Rosso' seedlings are also coming on nicely.

We were also very pleased to find a significant number of self-sown seedlings of the tomato 'Yellow Currant', this is a very vigorous bush variety, apparently blight-resistant, which produced a crop last year despite it being so unfavourable for tomatoes.
