Is it safe to eat cucumbers from a plant with spots?

Why are there spots on my cucumber leaves? Causes and fixes

Check these first

Look for white dust on the leaf surface.
Check for small beetles on the foliage.
Examine if the spots are dry or water soaked.

Likely causes

Powdery Mildew
Most likely
How to tell: White, dusty spots appear on the top of leaves, eventually covering the whole surface.
What to do: Improve air circulation by spacing plants further apart. Spray the leaves with a mixture of 1 tablespoon of baking soda in 1 gallon of water.
Bacterial Wilt
Possible
How to tell: Leaves develop irregular brown or yellow spots and the plant suddenly wilts despite having moist soil.
What to do: Remove and destroy the infected plant immediately to prevent spread. Control cucumber beetles, as they are the primary carriers of this bacteria.

When to worry

If the spots are accompanied by sudden wilting of the entire vine, it is likely bacterial wilt and the plant cannot be saved. Small isolated spots are manageable.

Stopping it coming back

Water at the base of the plant to keep foliage dry and ensure your garden has plenty of airflow.
