powdery mildew before it wreaks havoc on your vegetables!

1. Identification

Powdery mildew is an easily identifiable fungus characterized by white, powdery areas that spread across a plant’s foliage (usually the top side of leaves) and often its flowers as well. On the plus side, powdery mildew is host specific. So, just because one plant becomes infected doesn’t mean neighboring plants will, too.

However, powdery mildew consists of a wide range of species that infect an even wider range of host plants. Every group of plants, from ornamentals to edibles, shrubs to trees, has members that are commonly affected by powdery mildew. Make sure to do some basic research on the plants you choose for your garden to determine which pests and diseases you’re likely to come up against.

Some of the edibles most prone to powdery mildew include squash, cucumber, tomato, Swiss chard, basil, sage, mint, as well as strawberry, raspberry, and blueberry plants.
