The recently described species (Hou <em>et al.,<\/em> 2016) has only been reported from China, until its detection in California, USA.\u00a0 \u00a0In California, prior to the July 28, 2017 detection of <em>Colletotrichum aracearum<\/em> (see \u2018Initiating Event\u2019), there had been several detections of the pathogen which was then identified as <em>Colletotrichum<\/em> cf. <em>cliviae<\/em> (\u2018cf\u2019 in biological terminology means \u2018a significant resemblance to\u2019).\u00a0 However, those detections were recently shown to be <em>C. aracearum <\/em>(Kennedy, 2017; Latham, 2017).\u00a0\u00a0 The first detection of <em>C. aracearum<\/em> (then identified as <em>Colletotrichum<\/em> cf. <em>cliviae<\/em>) was made on April 28, 2015, from diseased <em>Dieffenbachia<\/em> sp. plants exhibiting leaf spots and detected in a nursery in San Diego County during regulatory nursery inspections by the San Diego County Agricultural officials. This marked a probable new U.S. record by the USDA National Identification Services at Beltsville, Maryland. Several detections followed from different nurseries within San Diego County.\u00a0 On June 11, 2015 and August 19, 2015, the same pathogen was detected in Chinese evergreen (<em>Aglaonema<\/em> sp.) leaves from cuttings that were shipped from Guatemala and intercepted by San Diego County, and from diseased <em>Aglaonema<\/em> sp. plants detected during regulatory nursery inspections.\u00a0 On December 3, 2015 and April 20, 2016, infected <em>Aglaonema<\/em> sp. were intercepted in plant shipments from Costa Rica, and on April 29, 2016, during\u00a0 regulatory nursery inspections, the pathogen was detected in <em>Cymbidium<\/em> sp. orchid plants showing leaf spots.\u00a0\u00a0 In all these cases, subsequent to the detection of the pathogen<em>, <\/em>infected plant shipments\/nursery stock were either destroyed or rejected from entering California. The presence and status of anthracnose disease caused by <em>C. aracearum<\/em> in Guatemala and Costa Rica have not been reported.<\/p>\n<p style=\"padding-left: 60px;\">Hosts: <em>Aglaonema<\/em> sp. (Chinese evergreen), <em>Cymbidium <\/em>sp. (orchid), <em>Dieffenbachia<\/em> sp. (CDFA detection records 2015-2017), <em>Monstera deliciosa<\/em> (Swiss cheese plant\/tarovine\/windowleaf), <em>Philodendron selloum<\/em> (cut-leaf philodendron) (Farr &amp; Rossman, 2016; Hou <em>et al.,<\/em> 2016).<\/p>\n<p style=\"padding-left: 60px;\">Symptoms:\u00a0 Generally, <em>Colletotrichum<\/em>-infected host plants exhibit symptoms of anthracnose which include dark brown leaf, stem, and fruit spots or lesions, fruit rot, and wilting of leaves which often result in dieback and reduction in plant quality.<\/p>\n<p style=\"padding-left: 60px;\">Damage Potential:\u00a0 Anthracnose disease caused by <em>Colletotrichum aracearum <\/em>can result in reduced plant quality and growth, fruit production and marketability.\u00a0 \u00a0Estimates of yield\/crop loss due to this pathogen have not been reported. However, in California, nursery and greenhouse production of orchids, Chinese evergreen, dieffenbachia, and other host plants are particularly at risk as nursery conditions are often conducive to infection by <em>Colletotrichum<\/em> species.\u00a0 In California\u2019s 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: 60px;\">Disease Cycle:\u00a0 It is likely that <em>Colletotrichum aracearum <\/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: 60px;\">Transmission:\u00a0 Wind, wind-driven rain, cultivation tools, and human contact.<\/p>\n<p style=\"padding-left: 30px;\"><strong><u>Worldwide Distribution<\/u>:<\/strong> <em>Asia<\/em>: China; <em>North America<\/em>: USA (Farr &amp; Rossman, 2017; Hou <em>et al.,<\/em> 2016).\u00a0 Currently, in the USA, <em>C. aracearum<\/em> has only been reported from California.<\/p>\n<p style=\"padding-left: 30px;\"><strong><u>Official Control<\/u>:\u00a0<\/strong> In California <em>C. aracearum<\/em> is an actionable, Q-rated pathogen, and infected plant material is subject to destruction or rejection.\u00a0 <em>Colletotrichum aracearum<\/em> is reportable to the USDA.<\/p>\n<p style=\"padding-left: 30px;\"><strong><u>California Distribution<\/u>:<\/strong> San Diego County (see \u201cBackground\u201d).<\/p>\n<p style=\"padding-left: 30px;\"><strong><u>California Interceptions<\/u>:\u00a0<\/strong> During 2015-17, four shipments of <em>Colletotrichum aracearum<\/em>-infected <em>Aglaonema<\/em> sp.
