Hosta ( / ˈhɒstə /, [5] syn. Funkia) is a genus of plants commonly known as hostas, plantain lilies and occasionally by the Japanese name gibōshi. Hostas are widely cultivated as shade-tolerant foliage plants. The genus is currently placed in the family Asparagaceae, subfamily Agavoideae, [6] and is native to northeast Asia ( China, Japan ...
Sclerotinia sclerotiorum is a plant pathogenic fungus and can cause a disease called white mold if conditions are conducive. S. sclerotiorum can also be known as cottony rot, watery soft rot, stem rot, drop, crown rot and blossom blight. A key characteristic of this pathogen is its ability to produce black resting structures known as sclerotia ...
Dry conditions can allow infected plants to recover and produce unaffected, fruit-producing branches. Erwinia papayae is a Gram-negative, straight rod bacterium with peritrichous flagella, so diagnosis can be made using a Gram stain. On King’s medium B, colonies are creamy and mucoid with a non-diffusible blue pigment (Vawdrey 2011).
Collar rot is a symptomatically described disease that is usually caused by any one of various fungal and oomycete plant pathogens. It is present where the pathogen causes a lesion localized at or about the collet between the stem and the root. The lesions develop around the stem eventually forming a "collar". Observationally, collar rot grades ...
This is typically at the crown of the strawberry, which is why it is often called crown rot. It is also known as the Anthracnose Crown rot. The fungus also infects leaves and is known as leaf spot, which is common among all Colletotrichum. This is not as common in the fragariae, as it is more common in the crown.
Colletotrichum cereale is a plant disease ( fungus) that has been found to cause crown rot anthracnose of turf grass most commonly occurring on golf courses (NC State 2012). Anthracnose can occur as both a foliar blight and basal rot (Penn State 2010). This disease attacks the crowns of plants, which is different than other anthracnose diseases.

Root-crown temperature has been found to affect plant growth and physiology in a number of ways. Root crowns need to be exposed and 'breathe'; this is one way that some plants take in oxygen. A number of pests and diseases affect specifically this part of the plant, including root-crown rot (or root-crown fungus) [2] and a number of species of ...
