I need some help please. My boys grew pumpkin plants this summer. One day we noticed that the leaves were turning white on a few of them. A closer look made us realize it was some type of mold. Well, the plants have since died. My problem now is that I have noticed the same mold begining on my Lilac bush. I really don't want to lose this. Can someone please help me? Maybe give a site that has any info on this.
I really appreciate it. Thank you!

Sounds like a case of powdery mildew. For remedies see,

Thanks again!
