PEST RATING PROFILE<\/strong><\/h5>\n
Initiating Event:<\/strong><\/h5>\n

On March 29, 2017, lavender (Lavendula<\/em> sp.) plants showing symptoms of leaf spots were detected in a nursery in San Luis Obispo County by County Agricultural officials.\u00a0 A sample of diseased leaves was sent to the CDFA Plant Pathology Laboratory for diagnosis.\u00a0 On May 8, 2017, Suzanne Latham, CDFA plant pathologist, identified the fungal pathogen, Septoria protearum<\/em> associated with the diseased leaf tissue.\u00a0 The pathogen was assigned a temporary Q rating.\u00a0 Subsequently, the consequences of introduction and establishment of S. protearum<\/em> in California are assessed and a permanent rating is proposed herein.<\/p>\n

History & Status:<\/strong><\/h5>\n

Background:<\/u> \u00a0<\/strong>\u00a0Septoria protearum<\/em> is a fungal pathogen that causes leaf spot disease in host plants.\u00a0 Septoria protearum<\/em> is the asexual (anamorph) stage, for which the sexual stage or teleomorph is not known.\u00a0 Verkley et al<\/em>., (2013) included the pathogen S. pistaciae<\/em> as a synonym of S. protearum <\/em>since it could not be robustly distinguished based on a seven-gene phylogenetic analysis. \u00a0Crous et al<\/em>., (2013) stated that further study and inoculation trials are needed to confirm synonymy of the two species.\u00a0 Also based on DNA evidence, Verkley et al.<\/em>, (2013) reported multiple host family associations for S. protearum<\/em>, which is unusual for other species of the genus. \u00a0Farr & Rossman (2017) included hosts of S. protearum<\/em> in genera belonging to nine families. The current CDFA detection of the pathogen in lavender, increases the number of represented families to ten. \u00a0Septoria pistaciae<\/em> (syn. S. protearum<\/em> according to Verkley et al.,<\/em> 2013) was previously reported from a pistachio orchard in California (Farr et al<\/em>., 1989; Michailides, 2005).<\/p>\n

Disease development<\/u>:<\/strong> While there is no specific information on the disease development of Septoria protearum<\/em> (Michailides, 2005), it is likely to be similar to that of other species in the genus.\u00a0 Generally, Septoria<\/em> spp. overwinter as mycelium and as conidia (asexual spores) within pycnidia (asexual fruiting structures) on or in seed and on diseased plant debris left in the field.\u00a0 Infected seeds produce infected seedlings that may result in damping-off or provide inoculum for subsequent infections.\u00a0 When pycnidia in infected plant debris become wet, they swell and conidia are exuded in long tendrils and thereafter, spread by splashing rain, irrigation water, as well as contaminated tools and animals.\u00a0 \u00a0\u00a0Septoria<\/em> species usually require high moisture for infection and severe disease development, however, they can cause disease under a wide range of temperatures (10-27\u00b0C) (Agrios, 2005).\u00a0 The teleomorph (sexual) stage of S. protearum<\/em> is unknown.<\/p>\n

Dispersal and spread:<\/em> Infected plants and nursery stock, splashing rain, irrigation water, plant leaf debris, contact with cultivation tools and animals (Agrios, 2005).<\/p>\n

Hosts:<\/em> \u00a0Presently, all reported hosts of Septoria protearum<\/em> are included in several families, viz<\/em>. Aspleniaceae, Proteaceae, Rutaceae, Rosaceae, Oleaceae, Boraginaceae, Davalliaceae, Anacardiaceae, Aracaceae, and Lamiaceae.\u00a0 Hosts include: Asplenium ruta-muraria<\/em> (walrue fern), Boronia denticulata<\/em> (mauve Boronia), Gerbera jamesonii<\/em> (Gerber daisy), Geum<\/em> sp. (Geum), Gevuina avellana <\/em>(Avellano\/Chilean hazelnut), Hedera helix <\/em>(common ivy\/English ivy), Ligustrum vulgare <\/em>(common privet\/ European privet), Masdevallia <\/em>sp. (Masdevallia), Myosotis <\/em>sp. (mouse\u2019s ear), Nephrolepis <\/em>sp. (fern), Pistacia vera <\/em>(pistachio), Protea cynaroides <\/em>(king protea), Protea <\/em>sp. (protea), Skimmia <\/em>sp. (Skimmia), Zantesdeschia aethiopica <\/em>(calla lily) (Crous et al<\/em>., 2008; Farr & Rossman, 2017; Verkley et al<\/em>., 2013).\u00a0 In addition, the pathogen was recently detected in Lavendula<\/em> sp. (lavender; Lamiaceae) (see<\/em>: \u2018Initiating Event\u2019).<\/p>\n

Symptoms<\/em>: \u00a0Leaf spots are produced in plants infected by Septoria<\/em> species.\u00a0 Leaf spots usually start on the lower leaves and progress upwards, \u00a0initiating as small yellowish specks that later enlarge, turn pale brown or yellowish gray, and finally dark brown.\u00a0 They are usually surrounded by a narrow yellow region and may be circular to irregular.\u00a0 Affected leaves may turn yellow and eventually die. Numerous small black pycnidia are aggregated and appear as dots within the leaf spots (Agrios, 2005). In pistachio, Septoria protearum<\/em> produces numerous, subcuticular brown spots, 0.5-1.5 mm on both sides of the leaf, with numerous black pycnidia clustered within the spots.\u00a0 In California, in pistachio fruit, the pathogen causes distinct grayish to light-brown fruit lesions, 1-4 mm in diameter, surrounded by a bright, distinctly reddish halo and usually located near the peduncle.\u00a0 Leaf infections have not been observed (Michailides, 2005).<\/p>\n

Damage Potential: <\/em>Quantitative losses due to Septoria protearum<\/em> have not been reported.\u00a0 Photosynthetic area can be reduced due to leaf spotting.\u00a0 In severe infections, leaf wilt, premature leaf drop, and reduced tree vigor may result. Leaf and fruit spots are produced in pistachio. \u00a0Leaf spot damage caused by S. protearum<\/em> may significantly impact production and marketing of nursery ornamental plants.<\/p>\n

Worldwide Distribution<\/u>:<\/strong> Africa<\/em>: South Africa; Europe<\/em>: France, Germany, Italy, Netherlands, Spain, Canary Islands; North America<\/em>: USA (California); Oceania<\/em>:\u00a0 New Zealand (Farr & Rossman, 2017).<\/p>\n

Official Control<\/u>:<\/strong> \u00a0No official control for Septoria protearum<\/em> has been reported.\u00a0 However, currently Septoria<\/em> spp. is on the \u2018Harmful Organism\u2019 list for the Bolivarian Republic of Venezuela (USDA-PCIT, 2017).<\/p>\n

California Distribution<\/u>:<\/strong> \u00a0Previous to its current detection, Septoria protearum<\/em> was reported from a pistachio orchard in California.\u00a0 Its recent detection was in a nursery in San Luis Obispo County (see<\/em> \u201cInitiating Event\u2019).<\/p>\n

California Interceptions<\/u>:<\/strong> \u00a0None.<\/p>\n

The risk Septoria protearum<\/em> would pose to California is evaluated below.<\/p>\n

Consequences of Introduction:\u00a0 <\/strong><\/h5>\n

1) Climate\/Host Interaction: <\/strong>Septoria protearum<\/em> has a diverse range of hosts which largely include several ornamental plant species. While the pathogen may be able to cause disease under cool and warm temperatures, it is dependent on high moisture for infection and severe disease development.\u00a0 Therefore, it is likely that the pathogen may be able to establish in a larger but limited area of California.<\/p>\n

Evaluate if the pest would have suitable hosts and climate to establish in California.<\/p>\n

Score: 2<\/span><\/strong><\/p>\n

– Low (1) Not likely to establish in California; or likely to establish in very limited areas.<\/p>\n

– Medium (2)<\/strong> may be able to establish in a larger but limited part of California.<\/span><\/p>\n

– High (3) likely to establish a widespread distribution in California.<\/p>\n

2) Known Pest Host Range:<\/strong> Presently, the pathogen has a moderate and diverse range of hosts inclusive of species in ten plant families.<\/p>\n

Evaluate the host range of the pest.<\/p>\n

Score: 2<\/span><\/strong><\/p>\n

– Low (1) has a very limited host range.<\/p>\n

– Medium (2)<\/strong> has a moderate host range.<\/span><\/p>\n

– High (3) has a wide host range.<\/p>\n

3) Pest Dispersal Potential: <\/strong>Septoria protearum<\/em> has high reproductive potential however, dispersal of conidia from pycnidia are dependent on wet conditions from splashing rain, dew, and irrigation water. Further artificial spread is caused by use of contaminated tools, animals, etc.\u00a0 Therefore, a \u2018Medium<\/strong>\u2019<\/span> rating is given to this category.<\/p>\n

Evaluate the natural and artificial dispersal potential of the pest.<\/p>\n

Score: 2<\/span><\/strong><\/p>\n

– Low (1) does not have high reproductive or dispersal potential.<\/p>\n

– Medium (2)<\/strong> has either high reproductive or dispersal potential.<\/span><\/p>\n

– High (3) has both high reproduction and dispersal potential.<\/p>\n

4)\u00a0Economic Impact: <\/strong>Septoria protearum<\/em> causes leaf and fruit spot in host plants.\u00a0 In California, it has been found in pistachio.\u00a0 Other hosts include several nursery-grown ornamental plant species.\u00a0 While there is no information on quantitative crop loss caused by this pathogen, leaf spot disease could lower crop value and cause loss of markets.\u00a0 Use of preventive chemical sprays and other control measures could increase production costs.\u00a0 Avoidance of overhead irrigations would require changes in cultural practices of irrigating plants.<\/p>\n

Evaluate the economic impact of the pest to California using the criteria below.<\/p>\n

Economic Impact: B, C, D<\/span><\/strong><\/p>\n

A. The pest could lower crop yield.<\/p>\n

B<\/strong>. The pest could lower crop value (includes increasing crop production costs).<\/span><\/p>\n

C<\/strong>. The pest could trigger the loss of markets (includes quarantines).<\/span><\/p>\n

D<\/strong>. The pest could negatively change normal cultural practices.<\/span><\/p>\n

E. The pest can vector, or is vectored, by another pestiferous organism.<\/p>\n

F. The organism is injurious or poisonous to agriculturally important animals.<\/p>\n

G. The organism can interfere with the delivery or supply of water for agricultural uses.<\/p>\n

Economic Impact Score<\/strong>: \u00a03<\/strong><\/span><\/p>\n

– Low (1) causes 0 or 1 of these impacts.<\/p>\n

– Medium (2) causes 2 of these impacts.<\/p>\n

– High (3)<\/strong> causes 3 or more of these impacts.<\/span><\/p>\n

5) Environmental Impact: <\/strong>\u00a0The pathogen could significantly impact ornamental plantings in home\/ urban, public gardens and other recreational environments.<\/p>\n

Evaluate the environmental impact of the pest on California using the criteria below.<\/p>\n

Environmental Impact: E<\/span><\/strong><\/p>\n

A. The pest could have a significant environmental impact such as lowering biodiversity, disrupting natural communities, or changing ecosystem processes.<\/p>\n

B. The pest could directly affect threatened or endangered species.<\/p>\n

C. The pest could impact threatened or endangered species by disrupting critical habitats.<\/p>\n

D. The pest could trigger additional official or private treatment programs.<\/p>\n

E<\/strong>. The pest significantly impacts cultural practices, home\/urban gardening or ornamental plantings.<\/span><\/p>\n

Environmental Impact Score: 2<\/span><\/strong><\/p>\n

– Low (1) causes none of the above to occur.<\/p>\n

– Medium (2)<\/strong> causes one of the above to occur.<\/span><\/p>\n

– High (3) causes two or more of the above to occur.<\/p>\n

Consequences of Introduction to California for Septoria protearum:<\/em><\/strong> \u00a0Medium (11)<\/strong><\/span><\/p>\n

Add up the total score and include it here.<\/p>\n

-Low = 5-8 points<\/p>\n

–Medium<\/strong> = 9-12 points<\/span><\/p>\n

-High = 13-15 points<\/p>\n

6) Post Entry Distribution and Survey Information<\/strong>: Evaluate the known distribution in California. Only official records identified by a taxonomic expert and supported by voucher specimens deposited in natural history collections should be considered. Pest incursions that have been eradicated, are under eradication, or have been delimited with no further detections should not be included.<\/p>\n

Evaluation is Low<\/em><\/strong>.<\/span>\u00a0 The pathogen was originally recorded in one pistachio orchard in California (county unknown) and since then has also been found in a nursery in San Luis Obispo.\u00a0 It is therefore, considered to have a localized distribution within the State.<\/p>\n

Score: -1<\/strong><\/span><\/p>\n

-Not established (0) Pest never detected in California, or known only from incursions.<\/p>\n

–Low (-1)<\/strong> Pest has a localized distribution in California, or is established in one suitable climate\/host area (region).<\/span><\/p>\n

-Medium (-2) Pest is widespread in California but not fully established in the endangered area, or pest established in two contiguous suitable climate\/host areas.<\/p>\n

-High (-3) Pest has fully established in the endangered area, or pest is reported in more than two contiguous or non-contiguous suitable climate\/host areas.<\/p>\n

Final Score:<\/h5>\n

7) The final score is<\/strong> the consequences of introduction score minus the post entry distribution and survey information score: (Score)<\/p>\n

Final Score: <\/em><\/strong><\/span>\u00a0<\/span>Score of Consequences of Introduction \u2013 Score of Post Entry Distribution and Survey Information = <\/strong><\/span><\/em>10<\/strong><\/span><\/p>\n

Uncertainty: \u00a0<\/strong><\/h5>\n

Distribution of Septoria protearum<\/em> in California is not fully known.\u00a0 Treatments with suppressive fungicides may have kept its spread in check.\u00a0 Also, a need for further research on taxonomic studies of the species has been mentioned in published literature.\u00a0 This information, when available, may alter the proposed rating for this pathogen.<\/p>\n

Conclusion and Rating Justification: <\/strong><\/h5>\n

Based on the evidence provided above the proposed rating for Septoria protearum<\/em> is B.<\/strong><\/p>\n
