“…The dispersal of V. dahliae propagules by irrigation water has been earlier demonstrated in several herbaceous crops (Easton et al 1969;Xiao et al 1998). Moreover, Thanassoulopoulos et al (1981) early suggested that water runoff after heavy rains or copious irrigation regimes could facilitate the movement of V. dahliae propagules in olive plantations soils.…”

“…Also, irrigation water can significantly increase pathogen inoculum densities in soil compared to a deficient irrigation regime, as reported in cauliflower (Brassica oleracea L. var. botrytis) (Xiao et al 1998). The same effect was observed in damp soil zones under the influence of drippers around olive trees (López-Escudero and Blanco-López 2005b).…”

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.

Scientific opinion on the pest categorisation of Verticillium dahliae Kleb

The European Commission requested the EFSA Panel on Plant Health to perform a pest categorisation of Verticillium dahliae Kleb., the fungal pathogen responsible for many Verticillium wilt diseases. V. dahliae is a single taxonomic entity, and sensitive and reliable methods exist for its detection and identification. V. dahliae is a highly polyphagous pathogen, affecting, overall, 400 cultivated and non-cultivated plant species. It is a hostadapted rather than a host-specific pathogen and has the ability to continuously widen its host range and develop races/pathotypes that can overcome host resistance or be more virulent on known hosts and host cultivars. V. dahliae is a vascular pathogen that causes wilt and plant death, thus impairing the growth and shortening the lifespan of its hosts. The pathogen is currently present in most parts of the risk assessment area, where yield reductions up to 50 % or more have been reported on some high value crops, including cotton, olive, potato, strawberry and ornamentals. There are no obvious eco-climatic factors limiting its potential establishment and spread in the non-infested part of the risk assessment area, where hosts are present. Once established, the pathogen can spread by both natural and human-assisted means. Movement of infected host plants for planting, especially asymptomatic plants, and seeds can introduce the pathogen (and its highly virulent races/pathotypes) into new areas. Application of integrated management strategies combined with disease risk assessment (assessment of the available soil-borne inoculum, determination of races/pathotypes present in the site, field cropping history) may reduce the impacts of Verticillium wilt in the risk assessment area, but it cannot eliminate the pathogen. V. dahliae is listed in Annex IIAII of Directive 2000/29/EC and, despite its wide host range, it is regulated only on Humulus lupulus (hop), for which the pathogen is considered of minor importance compared to V. nonalfalfae.

“…For other soilborne diseases, the impact of the irrigation method may not be so important. For example, Xiao et al (1998) reported no significant differences in incidence or severity of Verticillium wilt between drip-or furrow-irrigated cauliflower plots in California.…”
