Herbaceous landscape ornamentals can succumb to various adverse factors, including infectious and non-infectious diseases. Infectious diseases are caused by microorganisms, such as fungi, fungus-like water molds, bacteria, nematodes, viruses, and phytoplasmas. Abiotic or non-infectious diseases may be attributed to unfavorable growing conditions, which can include nutritional deficiencies, improper soil pH, extreme temperatures, excessive soil moisture, or drought.
