Powdery Mildew on Blueberry Leaves
I have several blueberry bushes that developed powdery mildew on the leaves, so said the people at the nursery. There are white spots that look dusty and it also affects the underside of the leaves. We had a rainy Spring and the bushes were not where they got full sun all day out in the open. That's being remedied now.
What should I use on the blueberry bushes that won't affect the fruit, or eating the fruit?
