Help re Sweet Williams attack

My Sweet William leaves have suddenly developed these blisters.  Is the bug (left hand leaf) to blame?  Should I pick off just affected leaves or dig up affected plants?

    Sorry this should have been in ‘problem solving’ section-rather than garden design section 😫

    I’m guessing bump is a way to move my query to the correct section, but if I knew what this comment meant I guess I’d have known how to do it!🤣

    "Bump" moves your query to the top of the "recent discussions" list where more people will see it.  And it really doesn't matter where you've posted it - most of us just go to the most recent posts and see if it's something we feel sufficiently knowledgeable to advise about.

    I'm by no means an expert but my guess is that you've got some sort of fungal leaf spot there.  They are often prevalent when the weather is damp and humid, or if the plant is frequently wetted by watering with - say - a sprinkler.  I suspect the bug may be a coincidence, though there are lots of sap-sucking bugs around too.

    You could remove and destroy the most damaged leaves, and try to water the plants at soil level rather than wetting the foliage.  Good ventilation will help so try to clear away any weeds around the plants.  A bit of sunshine might help too... 
    Since 2019 I've lived in east Clare, in the west of Ireland.

    American but the images look very similar.

    Thank you Liriodendron, the affected plants are very close to a rather vigorous lonicera syringantha so I’m guessing that has increased humidity somewhat, though we’ve not had too much rain.  I’ll trim them back and keep an eye on it.

    Thankyou Palustris yes it looks like the pictures shown on the site, rather than anything to do with the bug, so I will destroy affected bits and ventilate.
