Powdery Mildew

Hi All
Over the last five years or so I have been growing courgettes, squashes and cucumbers with varying levels of success - yup we all know courgettes grow regardless - but all of them have suffered from powdery mildew.  Primarily they have all been grown outdoors but this year I have grown one cucumber plant in my (sort of) greenhouse.  That has suffered more than any of the others but the fruits have been excellent and still keep coming even though the mildew has destroyed the lower leaves. 
So the questions are - Should I care?  If so what can I do? What should I do with the leaves, stems etc when the plant is done?

Thanks  Bob

    I struggle with powdery mildew too. I cut off the badly affected leaves and spray with a bicarb/washing up liquid mix. A teaspoon of Bicarb of soda and couple of drops of washing up liquid in a litre of water. It’s just about keeping it at bay.
