“…Obviously, a mandatory initial step for an effective VWO control is the implementation of certification programs aimed to produce pathogen-free olive plants (see below). It is also interesting to mention here one study suggesting that V. dahliae seed-transmission can also operate in olive, a situation which has been reported in herbaceous hosts (Toit et al 2005;Vallad et al 2005). Indeed, V. dahliae was detected in olive seeds by PCR-based assays (Karajeh 2006).…”

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.

“…V. dahliae has great genetic plasticity and is able to infect more than 200 plant species (1), including high-value annual and perennial crop plants, as well as landscape, fruit, and ornamental trees and shrubs (17,109). The list of the hosts infected by V. dahliae is continually expanding as disease outbreaks on new hosts are identified (16,43). One example of host range expansion occurred in lettuce in coastal California where entire crops have been lost to Verticillium wilt (150,161).…”

The genus Verticillium encompasses phytopathogenic species that cause vascular wilts of plants. In this review, we focus on Verticillium dahliae, placing emphasis on the controversy surrounding the elevation of a long-spored variant as a new species, recent advances in the analysis of compatible and incompatible interactions, highlighted by the use of strains expressing fluorescent proteins, and the genetic diversity among Verticillium spp. A synthesis of the approaches to explore genetic diversity, gene flow, and the potential for cryptic recombination is provided. Control of Verticillium wilt has relied on a panoply of chemical and nonchemical strategies, but is beset with environmental or site-specific efficacy problems. Host resistance remains the most logical choice, but is unavailable in most crops. The genetic basis of resistance to Verticillium wilt is unknown in most crops, as are the subcellular signaling mechanisms associated with Ve-mediated, race-specific resistance. Increased understanding in each of these areas promises to facilitate management of Verticillium wilts across a broad range of crops.

“…This field was weedy at that time and the major weed, Shepherd's purse (Capsella bursa-pastoris), a known host of V. dahliae , could have contributed to this increase. Although spinach was not considered a host of V. dahliae when the experiment began in , du Toit et al (2005 later reported that spinach seed crops can become infected with this pathogen; the extent to which fresh market production spinach harbors V. dahliae has not been documented. In our experiment, when spinach was present in the field, V. dahliae population in the soil was not affected in year 1 but slightly increased in year 2 (Figure 3).…”
