Can I compost plants with powdery mildew?

Jul 2019
Can I compost plants with powdery mildew in the City of Portland's yard debris pickup? I called Metro's Recycling Hotline. The person that I talked to wasn't familiar with powdery mildew, but suggested that I put the infected plants in the garbage rather than the yard debris.
