Abstract:
... Tomato gray leaf spot was first reported in Argentina in 1990. Since then, the disease has not only increased in endemic areas, but also disseminated in other tomato-growing areas. In a survey of plants with typical symptoms of Tomato grey leaf spot disease we isolated 27 Stemphylium representatives from the two main tomato-growing areas of Argentina. Cultural features such as sporulation, conidia ...

Abstract:
... Maize Lethal Necrosis Disease (MLND) develops from synergistic co-infection by Sugarcane mosaic virus and Maize chlorotic mottle virus. The disease causes symptoms ranging from leaf tissue mottling and malformed ears to premature plant death. Information on the diversity and transmission of those viruses are limited in Ethiopia. No attempts were made to characterize and identify SCMV and MCMV stra ...

Abstract:
... Tomato spotted wilt virus (TSWV), the type species of the genus Tospovirus in the family Bunyaviridae, is one of the most economically important emerging plant viruses worldwide. It causes over US$1 billion losses annually in open field and greenhouse-grown crops. A study was carried out to determine the geographical distribution, host range and phylogeny of TSWV in Zimbabwe. Disease surveys were ...

Abstract:
... The Ralstonia solanacearum species complex is one of the most destructive bacterial plant pathogens for many crops. Cavendish banana is an important staple food which is severely impacted by the bacterial wilt Moko disease, caused by R. solanacearum race 2. In Mexico, banana plantations comprise 75,000 ha, supporting the economy of more than 100,000 families. Moko disease is present in the states ...

Abstract:
... Citrus viroid VI (CVd-VI) is a viroid originally found from citrus and persimmon in Japan. We report here the identification and molecular characterization of CVd-VI from four growth regions of China. A total of 90 cDNA clones from nine citrus cultivars were sequenced. The sequence homologies of the Chinese CVd-VI and the reference sequence (NC_004359) vary from 94.2% to 97%. The sequence homologi ...

Abstract:
... Canna yellow streak virus (CaYSV), Canna yellow mottle virus (CaYMV), Bean yellow mosaic virus (BYMV), and Cucumber mosaic virus (CMV) were detected by reverse transcription-polymerase chain reaction in 16 local and introduced canna cultivars grown in the collection of the Nikita Botanical Gardens, Crimea. CaYSV was detected in all the cultivars tested, and most of the cultivars had mixed infectio ...

Abstract:
... Downy mildew caused by Peronospora sparsa is a major disease of blackberry (Rubus sp.) worldwide.
