Occurrence fungi causing black foot on young grapevines and nursery rootstock plants in Italy
(Firenze University Press, 2017)Young grapevine plants with decline and wood necrosis symptoms were collected from vineyards and nurseries in the Apulia and Molise regions, Italy, from 2013 to 2015. Isolations of fungi were prepared from 45 diseased ... -
Occurrence of fruit-decaying fungi on adult male Mediterranean fruit flies (ceratitis capitata) captured in orchards and adjacent vineyards
(South African Journal of Enology & Viticulture, 2004)The occurrence of adult male Ceratitis fruit flies and their potential to transmit fungi associated with pre- and postharvest decay of fruit in natura were investigated. Sensus fruit-fly traps were installed in orchards ... -
An overview of the biology, epidemiology and control of uncinula necator (powdery mildew) on grapevine, with reference to South Africa
(South African Society for Enology and Viticulture, 2001)Grape powdery mildew, caused by Uncinula necator, is the most widespread and destructive disease of grapevine. The disease can be found in most grape-growing areas of the world, including the tropics. In South Africa, ... -
Pathogenicity associated genes in Fusarium oxysporum f. sp. cubense race 4
(Academy of Science of South Africa, 2013)Fusarium oxysporum f. sp. cubense (Foc) is a fungus that infects banana roots and causes a destructive plant disease called Fusarium wilt. Foc consists of three pathogenic races (Foc races 1, 2 and 4), classified according ... -
Pathogenicity of South African Hymenochaetales taxa isolated from esca-infected grapevines
(Firenze University Press, 2015)Little is known about the pathogenicity and etiology of Hymenochaetales taxa associated with esca in South Africa. Ten South African Hymenochaetales taxa associated with esca in grapevine were subjected to basic enzyme ... -
Phylogeny and taxonomy of the scab and spot anthracnose fungus Elsinoe (Myriangiales, Dothideomycetes)
(Elsevier, 2017)Species of Elsinoe are phytopathogens causing scab and spot anthracnose on many plants, including some economically important crops such as avocado, citrus, grapevines, and ornamentals such as poinsettias, field crops and ... -
A protocol for molecular detection of Phaeomoniella chlamydospora in grapevine wood
(Academy of Science for South Africa, 2005)PETRI DISEASE IS A SERIOUS DECLINE AND dieback disease of young grapevines. The principal causal organism, Phaeomoniella chlamydospora, is distributed mainly by infected propagation material. Pathogen detection and accurate ... -
Resistance in uncinula necator to triazole fungicides in South African grapevines
(South African Society for Enology and Viticulture, 2000)The distribution of Uncinula necator variants resistant to triadimenol, penconazole and flusilazole were determined in vineyards with suspected resistance in the regions Tulbagh, Franschhoek, Stellenbosch, De Dooms, Riebeeck ... -
Species of Diaporthe on Camellia and Citrus in the Azores Islands
(Firenze University Press, 2018)Species of Diaporthe are important plant pathogens, saprobes, and endophytes on a wide range of plant hosts. Species such as D. citri are well-known on Citrus, as agents of pre- or post-harvest infections, causing dieback, ... -
Spray deposition and control of botrytis cinerea on grape leaves and bunches : part 1 (table grapes)
(South African Society for Enology and Viticulture, 2016)Insufficient quantity but also quality of spray deposition on susceptible grapevine tissue (i.e. target sites) and favourable conditions for pathogens could lead to control failure during high disease pressure situations. To ... -
Spray deposition and control of botrytis cinerea on grape leaves and bunches : part 2 (wine grapes)
(South African Society for Enology and Viticulture, 2016)Poor control of fruit and foliar diseases in vineyards is often attributed to insufficient spray deposition of susceptible tissue. To optimise spray deposition, a deposition assessment protocol using fluorometry, photo ... -
Transcriptome profiling of resistant and susceptible cavendish banana roots following inoculation with Fusarium oxysporum f. sp. cubense tropical race 4
(BioMed Central, 2012-08)Abstract Background Fusarium wilt, caused by the fungal pathogen Fusarium oxysporum f. sp. cubense tropical race 4 (Foc TR4), is considered the most lethal disease of Cavendish bananas ... -
Use of gamma irradiation for control of postharvest botrytis cinerea bunch rot of table grapes in cold storage
(South African Society for Enology and Viticulture, 1991)The feasibility of employing gamma irradiation for the control of postharvest Botrytis bunch rot of table grapes in cold storage was studied. Table grape cultivars from commercial vineyards in the Paarl and Hex River Valley ...
