Disease	Symptoms	Pathogen/Cause	Management
Cylindrocladium stem rot	Stems and lower leaves become very dark brown to black.	Cylindrocladium	This disease occurs during the propagation of plants from cuttings. When affected cuttings are placed on a wet paper towel in a plastic bag for a few days, many light-colored spores form on the infected tissue. Use pathogen-free rooting soil. Take cuttings from healthy plants.
Leaf spots	Dark brown spots spread to engulf the entire leaf.	Cercospora, Marssonina, Septoria, Stagonospora	Avoid sprinkler irrigation.
Powdery mildew	White fungal growth develops on the surface of leaves.	Erysiphe or Micosphaera	No control is available.
Rhizoctonia stem rot	Dark dead areas develop on the stems.	Rhizoctonia	This disease occurs during cutting propagation. When affected cuttings are placed on a wet paper towel in a plastic bag for a few days, web-like strands of fungal growth extend from the infected tissue to the towel surface. Use pathogen-free rooting soil. Take cuttings from healthy plants.
Rust	Reddish-brown dusty spores form on the leaves.	Puccinia andropogonis	This fungus also infects Oxalis, Penstemon, Mimulus, Lupinus, Baptisia, and Aesculus.
