“…Pomegranate transplants revealed the lowest means. Such results are in agreement with those reported by Walker (1992), Krol (2006), Ziedan and El-Mohamedy (2008), Kishore and Bhardwaj (2011), and Ziedan et al (2011). The pathogenicity tests proved that all isolated fungi from rotted root and/or wilted samples of transplants and young trees were pathogenic to fig, grapevine, and pomegranate transplants.…”

Root rot and wilt disease complex was detected in several fig (Ficus carica L.), grapevine (Vitis vinifera L.), and pomegranate (Punica granatum L.) transplants in nurseries and new orchards of the El-Kharga, Baris, Balate, El-Dakhla, and El-Farafrah districts, of the New Valley governorate, Egypt. The percentage of root rot/wilt incidence and severity on fig, grapevine, and pomegranate transplants in the surveyed districts differed. The average percentages of root rot/wilt incidence and severity, in the surveyed districts, were 41.26, 31.42% in fig, 38.2, 29.5% in grapevine, and 32.1, 23.7% in pomegranate transplants, respectively. The most frequently isolated fungi from rotted roots of fig, grapevine, and pomegranate transplants were Fusarium oxysporum, Rhizoctonia solani, and Macrophomena phaseolina. In pathogenicity tests, all the tested fungi were pathogenic to fig, grapevine, and pomegranate transplants. Under laboratory conditions, all of the following tested bio-agents: Azotobacter sp., Bacillus cereus, B. megaterium, and B. subtilis, were able to inhibit growth of the causal pathogens to different degrees. The effect of these bio-agents individually and/or mixed, when used as a soil drench treatment, were varied in reducing the incidence and severity of root rot/wilt diseases in fig, grapevine, and pomegranate transplants under greenhouse conditions. The mixed bio-agents gave the highest protection against root rot/wilt diseases compared with the individually used of bio-agents. All treatments significantly increased plant height, number of leaves/transplant, leaf area, fresh and dry weight/transplant compared with the control treatment.

“…The most destructive, though, were F. oxysporum, R. solani, and M. phaseolina. Symptoms of root rot and wilt disease of fig, grapevine, and pomegranate transplants were previously reported by Walker (1992), Omer et al (1999), Krol (2006), Ziedan and El-Mohamedy (2008), Kishore and Bhardwaj (2011), and Ziedan et al (2011).…”

Decline of grapevine due to soil borne fungi was surveyed during 2013-2015 summer growing seasons at El-Fayoum, El-Gharbeia and El-Beheira governorates, Egypt, Syndromes of declined grapevine plants included growth retardant of shoot system and root-rot as well as decrease of grapevine fruit yield quality. Isolation trails from root of declined trees of different grapevine cultivars i.e., superior, flame seedless, King robi and crimson was carried out. The most soil borne fungi associated with root-rotted grapevine were Fusarium oxysporum Schlechtend, Fusarium solani (Mart.) Sacc, Botryodiplodia theobromae, Rhizoctonia solani Kuhn and Macrophomina phaseolina(Tassi) Gold. Fusarium spp. are the main fungal associated with different infection types of declined root of grapevine either a singly or in combination with B. theobromae or R. solani as second infection type and third infection type with B. theobromae + R. solani. Under soil artificially infested with 5% (w/w) of each fungal isolates inocula of fourteen isolates obtained were varied for causing wilt and root-rot symptoms of grapevine trees and reducing growth parameters plant height, root length, root size, fresh and dry weight of shoot and root than the control. Botrydiplodia theobromae isolate No. (7) was the most caused root-rot and disease severity of shoot and root of grapevine plant(100%) followed by Fusarium avenacum caused (87.5%) of root-rot and disease severity of shoot and root. Fouthermore, Fusarium avenacum isolate was the most fungal isolate in reducing growth parameters expect root length. This is first record that Fusarium avenacum as a causal organism causing root rot disease of grapevine in Egypt.

“…have been occasionally reported (Garrido et al 2004;Gubler et al 2004;Zhang et al 2009;Ziedan et al 2011). In the following part we will exemplify the biocontrol of wilt and root rot caused by Fusarium spp., which are of regional importance, particularly in warm vine regions such as Australia, Brazil, Egypt (Garrido et al 2004;Highet and Nair 1995;Ziedan et al 2011) and may also cause problems in combination with phylloxera feeding (Granett et al 1998). Depending on the rootstock (Omer et al 1999), Fusarium oxysporum E.F. Sm.…”

“…Incidences on vineplants suffering from this fungus have been described recently in Egypt, where F. oxysporum isolates on grapevine plants (Cv. crimson) caused vascular wilt (on 66.7 % of the cases) and root-rot syndrome (33.3 %) (Ziedan et al 2011). Another species of Fusarium, F. solani Sny.…”

Use of beneficial bacteria and their secondary metabolites to control grapevine pathogen diseases

International audienceGrapevine is one of the most important economic crops yielding berries, wine products as well as derivates. However, due to the large array of pathogens inducing diseases on this plant, considerableamounts of pesticides—with possible negative impact on the environment and health—have been used and are currently used in viticulture. To avoid negative impacts of such products and to ensure product quality, a substantial fraction of pesticides needs to be replaced in the near future. One solution can be related to the use of beneficial bacteria inhabiting the rhizo- and/or the endosphere of plants. These biocontrol bacteria and their secondary metabolites can reduce directly or indirectly pathogen diseases by affecting pathogen performance by antibiosis, competition for niches and nutrients, interference with pathogen signaling or by stimulation of host plant defenses. Due to the large demand for biocontrol of grapevine diseases, such biopesticides, their modes of actions and putative consequences of their uses need to be described. Moreover, the current knowledge on new strains from the rhizo- and endosphere and their metabolites that can be used on grapevine plants to counteract pathogen attack needs to be discussed. This is in particular with regard to the control of root rot, grey mould, trunk diseases, powdery and downy mildews, pierce’s disease, grapevine yellows as well as crown gall. Future prospects on specific beneficial microbes and their secondary metabolites that can be used as elicitors of plant defenses and/or as biocontrol agents with potential use in a more sustainable viticulture will be further discussed
