Hi Emily , I have the same problem with the white powdery mildew on my yellow Zucchini plants. I cut off all the worst affected leaves and and fruit and put them in the rubbish bin. Then I washed the remaining leaves with a strong jet of water early in the morning and allowed to dry completely then I applied a mixture of Eco-oil and Neem Oil to the entire plant and surrounding soil at the recommended dose. After three applications, a week apart, the mould appears to be under control and my Zucchini's are looking good and fruiting again. Hope this helps Emily, good luck.

Hi Emily, WPM is annoying, I got it in my pumpkin patch a few years ago, Ted's treatment sounds effective. I got a 500ml spray bottle and put a tspn of bicarb soda in it and filled it with water, I then sprayed the leaves with it 3-4 times a week until they started to look healthier, I too removed some of the worst effected plants and burnt them, good luck and happy gardening, - Linda
