I have two Ogden Melon plants in my greenhouse and one of these
plants has what appears to be leaf curl on both the older leaves

Looking closely at these leaves I find lots of minute black
deposits on the underside - smaller than black fly and not moving.

Can anyone suggest what this might be and how to eradicate?

Quite possibly red spider mite. I spray with soft soap (Savona),
which is effective against pretty well every insect/mite except
scale, but melons may be one of the plants that doesn't like it.

The alternative is washing-up liquid solution with a dash of
methylated spirits, but the same plants that don't like soft soap
won't like that, either.

Thank you - I will try first one then the other if that doesn't work.
I don't want to lose the plant as I already have three egg sized melons.
