Infected nursery plants also aid in introducing and spreading the pathogen.<\/p>\n<p><em>Hosts:<\/em>\u00a0 <em>Phyllanthus acidus<\/em> (synonyms: <em>Cicca acida, P. distichus; <\/em>Tahitian gooseberry)<em>, P.benguetensis, P. emblica <\/em>(Indian gooseberry)<em>, P. niruri<\/em> (gale of the wind)<em>, P. phyllanthi, Phyllanthus sp. <\/em>(Dietrich &amp; Ko, 2015; Farr &amp; Rossman, 2016).\u00a0 Some <em>Phyllanthus<\/em> species such as, <em>P. emblica<\/em> and <em>P. acidus<\/em> are cultivated for fruit in warm climates, while other species are pantropical weeds or grown for medicinal uses \u2013 but these species are not present in California.<\/p>\n<p><em>Symptoms:<\/em>\u00a0 Rust-infected <em>Phyllanthus acidus<\/em> (Tahitian gooseberry) trees may exhibit a general unthrifty appearance with thinning canopy, and barren branches or twigs.\u00a0 Leaves exhibit discolored chlorotic or necrotic spots on upper and lower surfaces.\u00a0 Small white-brownish raised spots or pustules containing numerous powdery urediniospores are produced on lower leaf surfaces.\u00a0 Affected leaves eventually drop off.\u00a0 Rust pustules and lesions are also formed on the surface of fruit (Dietrich &amp; Ko, 2015).<\/p>\n<p><em>Disease Potential<\/em>:\u00a0 <em>Phyllanthus<\/em> species, such as <em>P. acidua<\/em> (Tahitian gooseberry) and <em>P. emblic<\/em>a (Indian gooseberry) grown for their fruit in tropical climates, are not commercially cultivated in California, but are probably sold by rare fruit nurseries within the State.\u00a0 Infections of this rust pathogen could negatively impact production and value of plants.\u00a0 In general, severe infestation of rust can result in defoliation and reduction in plant growth, vigor and stand.\u00a0 Containment and management of the rust pathogen can be difficult as masses of air-borne spores produced can spread over long distances.\u00a0 Backyard growers, other small, rare fruit production growers, hobbyists, and rare plant nurseries in warm and wet climates of southern California may be at particular risk.<\/p>\n<p><strong><u>Worldwide Distribution<\/u>:<\/strong> <em>Asia<\/em>: China, India, Indonesia, Malaysia, Philippines, Thailand; <em>North America<\/em>: USA (Florida, Hawaii); <em>South America:<\/em> Brazil, Ecuador, French Guyana, Venezuela (Dietrich &amp; Ko, 2015; Farr &amp; Rossman, 2016).<\/p>\n<p><strong><u>Official Control<\/u>:<\/strong> None reported.\u00a0 Presently, <em>Phakopsora phyllanthi<\/em> has a temporary Q rating in California.<\/p>\n<p><strong><u>California Distribution<\/u>:\u00a0<\/strong> The gooseberry rust pathogen, <em>Phakopsora phyllanthi<\/em> is not established in California.<\/p>\n<p><strong><u>California Interceptions<\/u>:\u00a0<\/strong> The pathogen has only been detected once in a single intercepted quarantine shipment of unidentified cut foliage that originated in Florida (see \u201cInitiating Event\u201d).<\/p>\n<p>The risk <em>Phakopsora phyllanthi<\/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.
