Powdery Mildew Update

Well, it’s been roughly 2 weeks since I first started treating my daisies infected with powdery mildew with Serenade, a biofungicide. Here’s the original post: Powdery Mildew.
Here are the results :
After 1 treatment there was a significant difference. The mildew disappeared for a few days leaving behind the brown spots of injury.  But as you can see, the mildew reappeared.

I treated a second time 7 days after the initial treatment. This time I was meticulous in covering every nook and cranny. Now, the plant has been mildew free for about 5 days. There are still damaged spots on the  leaves and some dried up Serenade spray, but NO MILDEW!
