Powdery mildew

My poor courgette has powdery mildew on it. It looks like grey powdery patches all over the leaves and stems. This is the first courgette I’ve planted it’s not the biggest one but I’m a little attached to this courgette. So far it’s been producing very well and we’ve been eating lots of yummy courgettes from it so I hope that I can save it. Powdery mildew can affect courgettes, pumpkins and cucumbers. I found this recipe in my NZ Gardener 2012 garden diary.
In a spray bottle dissolve 1 teaspoon of baking soda in 1 litre of water add a squirt of dishwashing liquid and shake. 

I only had a 500ml bottle so I just halved the recipe. I sprayed this solution all over my courgette; the top and underside of the leaves and the steams. When I sprayed the courgette the mildew seemed to disappear I guess I’ll just have to wait and see if it comes back. Fingers crossed it doesn’t but if it does I guess I’ll just spray it again. Will let you know how I go.
