Our tomato plants got powdery mildew problem, because of wildfire at west coast, there was not much sunlight, and even some leaves at top has powdery mildew problem, as you can see in the first picture.
I have already cut some leaves and branches at its bottom, so it looks neat, should I also cut those leaves at top with powdery mildew problem? Would it give negative effect to plant's health as it will have less leaves and there're a number of green tomatoes there already?
We tried to apply mix of water and milk (ratio is 1:1) to it, but because of the dust that wildfire created, it seems like it only makes the issue worse. Please let me know if you have better way to treat it. Thank you!
