mildew advise

My courgettes have finally got mildew. Last year I sprayed them with milk but it had little effect. Is it worth cutting the leaves off or is that just a waste of time?

Is there anything else one can do?

Having said that having the plants slow down a bit in their production may not be altogether a bad thing 

Courgette risotto..courgette bread..courgette soup..roast courgettes.. courgettes in the stew..............

that is what I hoped someone would say. There is enough to do as it is at the moment.

Do courgettes always get mildew?

Didn't really affect yield.

I cut off the leaves that got really bad
