Ewww...Mildewww
Yes it will affect the lantana and Echinacea, in fact, the list would be much shorter of what it Won't affect, flowers and shrubs (short list)columbine, dahlia, delphinium, honeysuckle, ivy, lilac, phlox, privet,roses,zinnia,begonias,and monarda. And if thats not enough, in the food garden it will attack:Peas,Turnips, Broccoli, Cauliflower, Radishes, Cucumbers, Melons, Pumpkins, Squash and Carrots!
Got Milk?
weekly sprays of milk controls powdery mildew just as effectively as synthetic fungicides.(1 part milk to 9 parts water)Or
1 tablespoon of baking soda with 2 1/2 teaspoons of light oil, and mix with one gallon of water. Spray this mixture evenly over the affected plants for 7-10 days, and water only when necessary. I am organic, what you use is YOUR choice, So I will say that on the chemical controls I list...please read the label for application rates and precautions, because I have no experience with them.
Daconil 2787 or Ortho Multi-purpose fungicide)

Powdery mildew is favored by dew, intermittent rain, or sprinkler irrigation. Susceptible flowers should be planted in open areas where they will not be crowded and where they are exposed to the sun. Plants in shade are more prone to mildew than those growing in the sun. Prune during the summer to thin out any dense foliage. This will increase aeration within the plant canopy. Avoid sprinkling at night during the month of August and September. Instead, soak the soil under plants as needed.
