Consequently, the shipment of <em>Iris<\/em> sp. plants was destroyed.\u00a0 The risk of infestation of <em>C. spaethianum <\/em>in California is evaluated and a permanent rating is proposed.\u00a0 <strong>\u00a0<\/strong>\u00a0<strong>\u00a0<\/strong><\/p>\n<h5><strong>History &amp; Status:<\/strong><\/h5>\n<p><strong><u>Background<\/u><\/strong>:\u00a0 The fungal pathogen <em>Colletotrichum spaethianum<\/em> was originally described in 1895 under the name <em>Vermicularia spaethiana<\/em> from dead stems of <em>Funkia univittata<\/em> (synonym <em>Hosta sieboldiana<\/em>) in Berlin, Germany.\u00a0 A living strain of the original material of pathogen is no longer available however, as a result of taxonomic and phylogenetic studies, Damm <em>et al.,<\/em> (2009) combined <em>V. spaethiana <\/em>to the genus <em>Colletotrichum<\/em> becoming <em>C. spaethianum<\/em> and designated an epitype (representative specimen in place of the non-available original specimen) from the same host in the same city as the original fungal species.<\/p>\n<p style=\"padding-left: 30px;\">Hosts: <em>Hosta sieboldiana<\/em>, <em>Hemerocallis<\/em> sp.(daylily), <em>H<\/em>. <em>flava<\/em>, <em>H.<\/em> <em>fulva<\/em>, <em>H.<\/em> <em>citrine, Hymenocallis americana <\/em>(northern spider lily), <em>Lilium<\/em> sp.

The CDFA detection of <em>Colletotrichum spaethianum<\/em> in <em>Iris<\/em> sp. is a new host record.<\/p>\n<p style=\"padding-left: 30px;\">Symptoms: \u00a0<em>Colletotrichum spaethianum <\/em>infected host plants exhibit symptoms of anthracnose which include reddish brown to dark brown leaf and stem necrotic spots and wilting of leaves which often result in dieback and reduction in plant quality.<\/p>\n<p style=\"padding-left: 30px;\">Damage Potential:\u00a0 Anthracnose disease caused by <em>Colletotrichum spaethianum <\/em>can result in reduced plant quality and growth, fruit production and marketability.\u00a0 Estimates of yield\/crop loss due to this pathogen have not been reported.\u00a0 Nursery production of potted host plants or in greenhouses are particularly at risk as nursery conditions are often conducive to infection by <em>Colletotrichum<\/em> species.\u00a0 In cultivated fields, disease development may be sporadic as it is affected by levels of pathogen inoculum and environmental conditions.<\/p>\n<p style=\"padding-left: 30px;\">Disease Cycle:\u00a0 It is likely that <em>Colletotrichum spaethianum<\/em> has a similar life cycle to that of other <em>Colletotrichum<\/em> species and survives between crops during winter as mycelium on plant residue in soil, on infected plants, and on seeds.\u00a0 During active growth, the pathogen produces masses of hyphae (stromata) which bear conidiophores, on the plant surface. Conidia (spores) are produced at the tips of the conidiophores and disseminated by wind, rain, cultivation tools, equipment, and field workers.\u00a0 \u00a0Conidia are transmitted to host plants.\u00a0 Humid, wet, rainy weather is necessary for infection to occur.\u00a0 These requirements in particular may limit the occurrence of the pathogen in California fields and subsequently, the pathogen may be more of a problem under controlled environments of greenhouses.\u00a0 Conidia germinate, penetrate host tissue by means of specialized hyphae (appresoria) and invade host tissue.<\/p>\n<p style=\"padding-left: 30px;\">Transmission:\u00a0 Wind, wind-driven rain, cultivation tools, and human contact.<\/p>\n<p><strong><u>Worldwide Distribution<\/u><\/strong>:\u00a0 Europe: Germany; Asia:\u00a0 South Korea; North America: Florida, South America: Oceania: New Zealand (Cai, <em>et al<\/em>., 2009; Damm et al., 2009; Farr &amp; Rossman, 2015; Yang, et al., 2009; Yang <em>et al<\/em>., 2014).<\/p>\n<p><strong><u>Official Control<\/u><\/strong>:\u00a0 In California <em>C. spaethianum <\/em>is an actionable, Q-rated pathogen, and infected plant material is subject to destruction or rejection. \u00a0\u00a0The species is considered \u2018reportable\u2019 by the USDA.<\/p>\n<p><strong><u>California Distribution<\/u><\/strong>: <em>Colletotrichum spaethianum<\/em> is not established in California (see \u201cInitiating Event\u201d).<\/p>\n<p><strong><u>California Interceptions<\/u><\/strong>:\u00a0 There has been one interception of <em>Colletotrichum spaethianum<\/em> \u2013infected (Iris) plants that originated in Oklahoma (see \u2018Initiating event\u2019).<\/p>\n<p>The risk <em>Colletotrichum spaethianum<\/em> would pose to California is evaluated below.<\/p>\n<h5><strong>Consequences of Introduction:\u00a0 <\/strong><\/h5>\n<p><strong>1) <span style=\"text-decoration: underline;\">Climate\/Host Interaction<\/span>:<\/strong> Evaluate if the pest would have suitable hosts and climate to establish in California.
