Following a request from the European Commission, the EFSA Panel on Plant Health performed a risk assessment of Xanthomonas citri pv. viticola (Xcv). This pest causes bacterial canker of grapevine and is reported from Brazil and India. Two scenarios were considered: scenario A0 (current practice) and A2 (additional control measures). For the fresh grape import pathway, scenario A0 results in an order of magnitude of about one entry per 10 years (median; 90% uncertainty interval between ca. one entry per 18,000 years and ca. five entries per year). For the Vitis spp. plants for planting for research/breeding purposes import pathway, the risk of entry is several orders of magnitude smaller than the risk due to fresh grape import. This outcome is also obtained under scenario A2. The key entry uncertainties include import volume and transfer (for plants for planting), transfer and the disaggregation factor (for fresh grapes) and the limited availability of epidemiological data. The extent of the area favourable for Xcv establishment in the EU is uncertain, illustrating the limitations of climate suitability assessments when based on few data points and little epidemiological information. Nevertheless, the risk of Xcv establishment is only slightly lower than the risk of Xcv entry, i.e. no major establishment constraints are expected for most entries. Similarly, the risk of Xcv establishment is assessed as only slightly lower under current climate compared to the climate of 2041–2060. For grapevine growing areas in the EU with average yearly temperature above 17°C, the lag phase between establishment and spread is expected to be about 3 years (median; 90% range between ca. 6 months and ca. 6 years). Under the same scenario, the rate of spread by natural means is assessed to be ca. 300 m/year (median; 90% range between ca. 35 and ca. 800 m/year). The spread rate would be considerably higher considering movements of plants and cutting tools or machinery. The percentage of grapevine plants infected by Xcv in production sites as yearly average over a 30‐year production cycle is estimated to be ca. 17% (median; 90% range between ca. 1.5% and ca. 46%) in table grapes and ca. 12% (median; 90% range between ca. 0.7% and ca. 37%) in wine grapes. Impacts have been reported to be severe in Brazil and India, but the estimates provided here show that there is considerable uncertainty about expected impacts in the EU.

“…Reports in Brasil of P. euvitis date back to 2001 on vines (Vitis spp.) in the municipality of Jandaia do Sul in the State of Paraná, by Tessmann et al (2004), since then, this phytopathogenic fungus has been described in other Brazilian regions, including the states of Goiás, São Paulo, Rio Grande do Sul and Mato Grosso (Tessmann et al, 2004;Souza, 2004, Gomes et al, 2016Menezes Filho et al, 2020).…”

Phakopsora euvitis is a phytopathological fungal species described in plants of Vitis sp. This study aimed to report the first case of fungal infestation of P. euvitis in the botanical genus Plumeria, Plumeria rubra in Rio Verde, Goiás, Brasil. Leaves showing P. euvitis urediniospore infestation were collected at Instituto Federal Goiano, Rio Verde, Goiás, Brasil, in the gardens of the central library. The plant and fungal species were identified by a specific dichotomous key for both genera. Slides were prepared with glycerin and micrographed under an optical microscope. As for the dimensions of P. euvitis urediniospores in this study, they presented length and width of 15.12 – 24.47 x 13.11 – 15.69 µm, sessile with slightly elongated peduncles, some abruptly elongated, ovoid, ovoid-ellipsoid and oblong-ellipsoid in only one hemisphere. Further studies should be carried out evaluating by histology the areas infected by Phakopsora euvitis in Plumeria rubra to understand the option of this fungus outside the genus Vitis and its evolution in this botanical species.

“…Entretanto, os autores constataram por meio de uma pesquisa de campo que a ferrugem estava presente também em outras localidades do estado do Paraná. Em 2003, o fungo foi encontrado também em Indaiatuba, Itupeva, Louveira e outras áreas do estado de São Paulo (Tessmann et al, 2004) e no estado do Mato Grosso (Souza, 2004).…”

Estudos epidemiológicos e controle químico de Phakopsora euvitis

Em janeiro de 2003 foram constatados sintomas típicos de ferrugem em folhas maduras de videira (Vitis vinifera), nas áreas experimentais da Universidade Estadual Paulista, Campus de Ilha Solteira, em Selvíria - MS e Ilha Solteira - SP. Este é o primeiro relato desta doença da videira no Centro-Oeste do Brasil. Considerando a intensidade da doença, a importância da cultura da videira na região e a falta de informações sobre a ferrugem, os objetivos deste trabalho foram: reconfirmar a patogenicidade de Phakopsora euvitis; estudar a influência da luz e da temperatura na germinação de urediniósporos; estudar o efeito do tipo de superfície na germinação de urediniósporos; determinar a longevidade in vivo de urediniósporos e avaliar a eficiência agronômica de fungicidas para o controle da ferrugem. Sintomas da ferrugem foram verificados somente em folhas maduras de videira. A temperatura de 25 ºC, no escuro, e a superfície inferior da folha de videira foram as melhores condições para a germinação de urediniósporos de P. euvitis. A germinação dos urediniósporos foi reduzida em 94%, em folhas de videira que foram retiradas das plantas e mantidas durante sete dias na superfície do solo. Em dois experimentos realizados em campo constatou-se que os fungicidas tebuconazole, propiconazole e azoxystrobin proporcionaram as menores intensidades da doença. Tebuconazole apresentou-se como o fungicida mais eficiente no controle da ferrugem. No geral, maior intensidade da ferrugem foi observada em videira conduzida no sistema de espaldeira.
