In all cases of interceptions mentioned afore, subsequent to the detection of C. asianum, all fruit and plant shipments were received from Florida and either destroyed or rejected from entering California.\u00a0 Currently, <em>C. asianum <\/em>has a temporary \u2018Q\u2019 rating.\u00a0 The risk of introduction and establishment of this pathogen in California is assessed and a permanent rating is proposed herein.\u00a0\u00a0\u00a0 \u00a0\u00a0\u00a0\u00a0\u00a0\u00a0\u00a0<strong>\u00a0<\/strong><\/p>\n<h5><strong>History &amp; Status:<\/strong><\/h5>\n<p><u>Background<\/u>:\u00a0 <em>Colletotrichum asianum<\/em> was first reported to be associated with coffee berries (<em>Coffea arabica<\/em>) in northern Thailand (Prihastuti <em>et al<\/em>., 2009).\u00a0 The pathogen is a distinct fungus species belonging to the vastly morphological and physiological variable <em>C. gloeosporioides <\/em>complex and is generally identified from other species of the complex only with DNA sequences (Prihastuti <em>et al.,<\/em> 2009; Weir <em>et al<\/em>, 2012).<\/p>\n<p style=\"padding-left: 30px;\"><em>Hosts<\/em>: <em>Mangifera indica<\/em> (mango) and <em>Coffea arabica<\/em> (coffee) (Prihastuti <em>et al<\/em>., 2009; Weir <em>et al<\/em>., 21012).<\/p>\n<p style=\"padding-left: 30px;\"><em>Symptoms<\/em>:\u00a0 Initially, small, dark brown circular spots are produced on mango fruit and leaves infected with <em>Colletotrichum asianum<\/em>.\u00a0 These spots increase rapidly in size and coalesce to form dark depressed anthracnose lesions in ripened fruit (Krishnapillai &amp; Wilson Wijeratnam, 2014). Generally, <em>Colletotrichum<\/em>-infected host plants exhibit symptoms of anthracnose which include dark brown leaf, stem and fruit spots and wilting of leaves which often result in dieback and reduction in plant quality.<\/p>\n<p style=\"padding-left: 30px;\"><em>Damage Potential<\/em>:\u00a0 Anthracnose disease caused by <em>Colletotrichum asianum <\/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;\"><em>Disease Cycle<\/em>:\u00a0 It is likely that <em>Colletotrichum asianum<\/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;\"><em>Transmission<\/em>:\u00a0 Wind, wind-driven rain, cultivation tools, and human contact.<\/p>\n<p><strong><u>Worldwide Distribution<\/u>:<\/strong>\u00a0 <em>Africa<\/em>: South Africa; <em>Asia<\/em>: Japan, Sri Lanka, Thailand, Philippines; <em>South America<\/em>: Brazil, Colombia, Panama; <em>Australia<\/em>; <em>North America<\/em>: Florida (Farr &amp; Rossman, 2015; Krishnapillai &amp; Wilson Wijeratnam, 2014; Lima <em>et al<\/em>., 2013; Prihastuti <em>et al<\/em>., 2009; Sharma <em>et al<\/em>., 2013; USDA, 2015; Vieira <em>et al<\/em>., 2014; Weir et al., 2012).<\/p>\n<p><strong><u>Official Control<\/u>:\u00a0<\/strong> In California <em>C. asianum<\/em> is an actionable, Q-rated pathogen, and infected plant material is subject to destruction or rejection.<\/p>\n<p><strong><u>California Distribution<\/u>:<\/strong> <em>Colletotrichum asianum<\/em> is not established in California (see \u201cInitiating Event\u201d).<\/p>\n<p><strong><u>California Interceptions<\/u>:\u00a0<\/strong> During 2015, <em>Colletotrichum asianum<\/em> has been intercepted several times mainly in shipments of mango fruit and less frequently in mango plants (leaves) that originated in Florida (see \u2018Initiating event\u2019).<\/p>\n<p>The risk <em>Colletotrichum asianum<\/em> would pose to California is evaluated below.<\/p>\n<h5><strong>Consequences of Introduction:\u00a0 <\/strong><\/h5>\n<p><strong>1) Climate\/Host Interaction:<\/strong> Evaluate if the pest would have suitable hosts and climate to establish in California.
