By Karl Schultz, Austin, TX
First step in getting rid of powdery mildew is don't over fertilize or over water. Rapid, unnatural plant growth makes new shoots susceptible to powdery mildew. Sunlight helps keep powdery mildew at bay. Avoid planting sun loving plants such as tomatoes in shady areas where mildew will thrive.
Try to pick varieties of garden plants that are resistant. See list below.
Allow space between plants for good air flow to prevent the spread of powdery mildew from plant to plant.
Remove powdery mildew infected plants and dispose of them. This prevents powdery mildew from getting a foothold in your garden.
Next step in getting rid of powdery mildew in your garden is to not over prune since new shoots are more susceptible to mildew.
If you must use a fungicide for powdery mildew, try and choose one with the least environmental impact. These include Safer Garden Fungicide Sulfur, Green Light Neem Concentrate
and Bonide Remedy. Read all label warnings since some are mildly or moderately toxic to pets and aquatic life but do not last long in the environment since they break down easily.
Plants that are resistant to powdery mildew include Crape Myrtle, Squash, Phlox, Roses, and many other under the proper conditions as described above.
