Cucumbers

I've got yellow spots on my cucumber leaves but otherwise the plant looks health.  Does anyone know what it is and how to treat it?

Mother Goose,it is likely Cucumber Mosaic a fungus spread by damp, insects, or even wind blown.
Try keeping the leaves dry when watering, give plenty of air movement and you could look in one of the garden centres for a spray, we would have used Bordeaux mixture years ago I have no idea what H&S want us to use in its place.
You could try gently wiping the leaves with a drop of warm water with a splash of washing up liquid, that works for me on many plants including roses although I use it as a spray on those.
Your cucumbers should be OK though>

Frank, I do have some Vitax Bordeaux mixture which I used in the early stages of my vegetable growing this year (Monty Dons advice) to avoid any damping off is this the same stuff?  If not I will take your advice and do the washing up liquid.  Thanks
