Một tổng quan về bệnh lúa mì Fusarium hạt nhỏ ngũ cốc - Fusarium ear blight (scab) Dịch bởi AI Tập 44 Số 2 - Trang 207-238 - 1995
D. WYNN PARRY, Peter Jenkinson, Lynette J. McLeod
Tổng quan này về bệnh Fusarium trên hạt nhỏ ngũ cốc cho thấy có tới 17 loại tác nhân gây bệnh đã được xác định có liên quan đến căn bệnh đang phổ biến ở hầu hết các khu vực trồng ngũ cốc trên thế giới. Các loài phổ biến nhất là Fusarium graminearum (Gibberella zeae), F. culmorum, F. avenaceum (G. avenacea), F. poae và Microdochium nivale (Monographella nivalis). Bệnh được ghi nhận phổ biến...... hiện toàn bộ

Seed degeneration in potato: the need for an integrated seed health strategy to mitigate the problem in developing countries Tập 65 Số 1 - Trang 3-16 - 2016
S. Thomas‐Sharma, Abdulwahab Abdurahman, Sajid Ali, Jorge Andrade-Piedra, Siqin Bao, Amy O. Charkowski, Darren Crook, M. S. Kadian, Peter Kromann, P.C. Struik, L. Torrance, Karen A. Garrett, G. A. Forbes
Seed potato degeneration, the reduction in yield or quality caused by an accumulation of pathogens and pests in planting material due to successive cycles of vegetative propagation, has been a long‐standing production challenge for potato growers around the world. In developed countries this problem has been overcome by general access to and frequent use of seed, produced by specialized gr...... hiện toàn bộ
Elucidation of the infection process of Ustilaginoidea virens (teleomorph: Villosiclava virens) in rice spikelets Tập 62 Số 1 - Trang 1-8 - 2013
Tang Yu-qi, Jie Jin, Dongwei Hu, Mingli Yong, You‐Ping Xu, Lishan He
This study reports an efficient inoculation protocol that allowed cytological analysis of the infection process of the rice false smut pathogen Ustilaginoidea virens. Examination of serial semithin and ultrathin sections of infected spikelets showed that the primary infection sites for the pathogen were the upper parts of the three stamen filaments located betwee...... hiện toàn bộ
Use of next‐generation sequencing for the identification and characterization of Maize chlorotic mottle virus and Sugarcane mosaic virus causing maize lethal necrosis in Kenya Tập 62 Số 4 - Trang 741-749 - 2013

The diagnosis of novel unidentified viral plant diseases can be problematic, as the conventional methods such as real‐time PCR or ELISA may be too specific to a particular species or even strain of a virus, whilst alternatives such as electron microscopy (... hiện toàn bộ
Studies on thiabendazole resistance of Penicillium expansum of pears: pathogenic fitness and genetic characterization Tập 52 Số 3 - Trang 362-370 - 2003
Elena Baraldi, Marta Mari, Elena Chierici, M. Pondrelli, P. Bertolini, G.C. Pratella
Isolates of Penicillium expansum recovered from stored pears were scored for resistance to the fungicide thiabendazole (TBZ) and for pathogenic fitness. Out of 50 isolates, nine were sensitive (S) and 41 resistant (R or RR). Seven of these resistant isolates (RR) germinated with a higher percentage on TBZ‐amended medium than on unamended medium. Six S isolates an...... hiện toàn bộ
Phylogenetic relationships and pathogenicity of Colletotrichum acutatum isolates from grape in subtropical Australia Tập 56 Số 3 - Trang 448-463 - 2007
Melanie A. Whitelaw-Weckert, Shaun J. Curtin, Rong Huang, Christopher Steel, Christopher Blanchard, Paul Roffey
The identity of Colletotrichum acutatum as the causal pathogen of grape ripe‐rot, which causes yield loss and a bitter taint that lowers wine quality in Australian subtropical wine‐grape regions, was confirmed using species‐specific primers. Cultural, morphological and molecular methods (RAPD‐PCR and sequencing of parts of the 5·8S‐ITS regions and the β‐tubulin‐2...... hiện toàn bộ
Inheritance of resistance to carboxylic acid amide (CAA) fungicides in Plasmopara viticola Tập 56 Số 2 - Trang 199-208 - 2007
U. Gisi, Maya Waldner, N. Kraus, Pierre-Henri Dubuis, Helge Sierotzki
Mandipropamid is a new mandelic acid amide fungicide expressing high activity against foliar infecting oomycetes, including the grapevine downy mildew, Plasmopara viticola. Because cross‐resistance with the valinamide fungicides iprovalicarb and benthiavalicarb and the cinnamic acid amide fungicides dimethomorph and flumorph was postulated, all five compounds are...... hiện toàn bộ
