“…Also many forest tree species are susceptible to V. dahliae infections (Sinclair et al 1987;Hiemstra and Harris 1998;Pegg and Brady 2002, and references therein). Finally, because of the epidemiological implications, it is worth mentioning the susceptibility of a large number of weeds to this pathogen (Thanassoulopoulos et al 1981;Vargas-Machuca et al 1987;Yildiz et al 2009). …”

“…Related to this, many susceptible weeds are broadleaf genera frequently found in olive groves (i.e., Anagallis, Lamium, Malva, Matricaria, Medicago, Senecio, Solanum, Veronica, etc.) thus contributing to the proliferation and dispersal of the pathogen in the soil (Thanassoulopoulos et al 1981;Vargas-Machuca et al 1987;Heale 1988;Ligoxigakis et al 2002;Uremis 2005;Yildiz et al 2009). Although monocot species, both cultivated and weeds, are not considered V. dahliae hosts, surface root colonization in oat, barley, corn or wheat has been reported (Benson and Ashworth 1976;Levy and Isaac 1976).…”

Verticillium wilt of olive: a case study to implement an integrated strategy to control a soil-borne pathogen

Olive (Olea europaea L.) is one of the first domesticated and cultivated tree species and has historical, social and economical relevance. However, its future as a strategic commodity in Mediterranean agriculture is threatened by diverse biotic (traditional and new/emerging pests and diseases) and abiotic (erosion, climate change) menaces. These problems could also be of relevance for new geographical areas where olive cultivation is not traditional but is increasingly spreading (i.e., South America, Australia, etc). One of the major constraints for olive cultivation is Verticillium wilt, a vascular disease caused by the soil-borne fungus Verticillium dahliae Kleb. In this review we describe how Verticillium wilt of olive (VWO) has become a major problem for olive cultivation during the last two decades. Similar to other vascular diseases, VWO is difficult to manage and single control measure are mostly ineffective. Therefore, an integrated disease management strategy that fits modern sustainable agriculture criteria must be implemented. Multidisciplinary research efforts and advances to understand this pathosystem and to develop appropriate control measures are summarized. The main conclusion is that a holistic approach is the best strategy to effectively control VWO, integrating biological, chemical, physical, and cultural approaches.

“…Portulaca oleracea L. (Portulaceae) which is known as purslane "Rigla" or "Begla" in Arabic is edible and used fresh as salad or cooked as a vegetable similar to Spinach. It is also used in traditional Chinese folk medicine and in many regions it is considered as invasive weed [11]. It has been reported to have antifungal and antibacterial activities [12][13][14].…”

Seedborne fungi present on or inside the seed or as contaminant with the seed debris adversely affect seed viability, germination, emergence, plant growth vigour and eventually production and productivity. In the present study, seedborne fungi of 7 imported vegetables were examined. 29 species of fungi belonging to 23 genera were recovered from the seeds. Of these fungi, 6 species and one genus are new records to the mycoflora of Sudan, whereas different species are new to the micobiota of these vegetables. These include 15 species for Beta vulagris, Petroselinum crispum (14 species), Solanum melongena (12 species), Portulaca oleracea (8 species and 1 genus), Eruca sativa (5 species and 3 genera), Corchorus olitorius (2 species), and Cucumis sativa (1 species). The seeds were highly contaminated with saprophytic and pathogenic fungi (25-100%), which apparently inhibited seed germination (15-79%) and seedling emergence (12-75%) of these vegetables. The genus Aspergillus and Drechslera (4 species each) were the most prevalent genera followed by Alternaria, Curvularia, Fusarium, Pithomyces (2 species) and 1 species for the remaining genera (Aureobasidium, Beltrania, Chaetomium, Cladosporium, Memnoniella, Microascus, Rhizopus, Sordaria, Stachybotrys, Stemphylium, Trichothecium, Ulocladium, and Wellernia). Therefore, there is urgent need for development of proper standard laboratory seed testing methods, fungal eradication measures, and adopting strong legislations and quarantine regulations. The use of certified and high grade seeds is a priority.
