    Noticed my first case of rust fungus yesterday. My boots had that orange residue. Also spotted a case of slime mold fungus. Anybody else seeing fungus problems?

    Fair amount of brown patch, some dollar spot, a little pythium. Necrotic ring spot this spring. Haven't seen a good case of rust in a while.

    I'm seeing lots of rust on daylillies, and powdery mildew on roses and crape myrtles, had some brown patch earlier

    Yep. Hi Riggle. While Iowa State University says it is common on Kentucky bluegrass and Ryegrass cultivars, we almost ALWAYS see this prob on ryegrass. See Ohio State, cuz they have the most research regarding rust... I hate ryegrass for two reasons: 1) Rust, 2) Many ryegrasses tend to gow in "clumps" - not filling in the bare spots like Kent:waving: ucky bluegrass does.
