“…Stock seeds should be produced in those areas associated with the lowest disease risk, and the seeds subjected to standardized seed health analysis (Munkvold, ). The availability of good diagnostic tools and early pathogen detection represent the best preventative measures in many cases (Thomas et al ., ), as has been observed for the case of P. cucumerina on wild rocket (Gilardi et al ., ) as well as for formae speciales and races of F. oxysporum from seeds, plants and soil samples (Pasquali et al ., ; Mbofung & Pryor, ; Gilardi et al ., ).…”

Emerging foliar and soil‐borne pathogens of leafy vegetable crops: a possible threat to Europe

Italy is one of the leading countries for the production and consumption of ready‐to‐eat salads. This has led to a steady increase in the area used over the last decade for the growth of leafy vegetables under intensive systems. The recent new diseases that affect lettuce, wild and cultivated rocket, lamb's lettuce, spinach and basil are reported here: Plectosphaerella cucumerina on wild rocket, endive and lamb's lettuce, Fusarium equiseti on wild and cultivated rocket and lettuce, Myrothecium verrucaria on spinach and wild rocket, Myrothecium roridum on lamb's lettuce, Allophoma tropica on lettuce and Alternaria sp. on basil and rocket are among the new foliar pathogens in Italy. Among the soil‐borne pathogens, Pythium aphanidermatum, Pythium irregulare and Pythium Cluster B2a have recently been isolated in Italy on spinach and Swiss chard, lamb's lettuce and lettuce, while Fusarium oxysporum f. sp. lactucae, which causes lettuce wilt, is gradually spreading to new countries. Some of the new pathogens have been found to be transmitted by seed and typical of tropical climate, and are thus favoured by the increases in temperature linked to climate change. The globalization of markets, climate change and intensive cultivation are among the factors responsible for the proliferation and spread of some of these new pathogens that are ‘alien’ to Italian production systems.

“…Best-available practices for pest management include, for example, production of clean seed and planting material, early warning systems, good diagnostic tools, and effective treatments such as seed dressings (Gullino, Gilardi and Garibaldi, 2014b;Gullino and Munkvold, 2014;Munkvold, 2009;Munkvold and Gullino, 2020;Thomas et al, 2017), together with the associated sampling and monitoring. Other best-available practices include the use of resistant cultivars when available, the adoption of cultural practices promoting plant health, integrated pest-management systems, the application of rigorous hygiene measures, and the use of biological crop-protection products.…”

“…The quantification of infectious spore loads of plant pathogens through properly designed aerobiological assays may be pivotal to implementing effective surveillance networks and early warning systems for plant protection and biosecurity enhancement (Thomas et al, 2017). In addition, unravelling the temporal or spatial propagule deposition patterns of target plant pathogens may shed light on their biology, ecology, and epidemiology.…”

“…In addition, unravelling the temporal or spatial propagule deposition patterns of target plant pathogens may shed light on their biology, ecology, and epidemiology. A better understanding of such aspects can lead to better plant disease management (Garbelotto et al, 2017; Gonthier et al, 2005; Thomas et al, 2017). Although different aerobiological assays are available (reviewed in Jackson & Bayliss, 2011; West & Kimber, 2015), they all rely on spore trapping devices collecting airborne propagules, and on diagnostic methods detecting and quantifying propagules of target pathogens.…”
