What to do with Powdery Mildew on Pumpkin Leaves

I have powdery mildew on my pumpkin leaves. Bought fungicide from nursery. Shall I remove ALL the infected leaves? Or shall I spray them with fungicide and NOT remove leaves? Fungicide spray does not provide instructions for removing infected leaves. Any other advice will be greatly appreciated! Pasadena, CA -- Thank You!

Hi, You can spray the entire vine with the fungicide following label directions. This won't cure the affected leaves but should protect new foliage.  I would not remove the infected leaves because that could defoliate the plant. I'd leave them in place, and remove them if they die or when the plants finish in the fall.
