Baptisia Diseases
Gary W. Moorman, Professor of Plant Pathology
| Disease | Symptoms | Pathogen/Cause | Management |
|---|---|---|---|
| Cylindrocladium stem rot | Stems and lower leaves become very dark brown to black. | Cylindrocladium | This disease occurs during 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 extends 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, Mumulus, lupines, Baptisia, and Aesculus. |
