“…Studies in the last few decades on pathogenic members of the Phytophthora genus and of the Botryosphaeriaceae and Xylariaceae families have partially filled the gap. Moreover, research conducted in different countries in Africa, Europe, and North America has contributed to expanding knowledge about the pathogenicity, epidemiology, biology, invasiveness, and management of some of these pathogens in different oak forests (Dreaden et al 2014a;Kostovcik et al 2015;Linaldeddu et al 2013;Lynch et al 2013;MoralesRodríguez et al 2016;Moreira and Martins 2005;Serrano et al 2015). Detailed and modern morphological descriptions coupled with DNA sequence data currently available in public databases are facilitating the identification of taxa (Martin et al 2014;Phillips et al 2013).…”

“…Two studies conducted recently in Spain showed the effectiveness of benzimidazole fungicides (thiophanate-methyl and carbendazim) in reducing the incidence and severity of D. corticola cankers under field conditions (Luque et al 2008;Serrano et al 2015). However, the increasing restriction of fungicides for the control of fungal diseases in agriculture and forestry prompts an effort to identify new environmentally friendly control strategies.…”

Cork oak (Quercus suber) forests are economically and culturally intertwined with the inhabitants of the Mediterranean basin and characterize its rural landscape. These forests cover over two million hectares in the western Mediterranean basin and sustain a rich biodiversity of endemisms as well as representing an important source of income derived from cork production. Currently cork oak forests are threatened by several factors including human-mediated disturbances such as poor or inappropriate management practices, adverse environmental conditions (irregular water regime with prolonged drought periods), and attacks of pathogens and pests. All these adverse factors can interact, causing a complex disease commonly known as “oak decline.” Despite the numerous investigations carried out so far, decline continues to be the main pathological problem of cork oak forests because of its complex etiology and the resulting difficulties in defining suitable control strategies. An overview of the literature indicates that several pathogenic fungi and oomycota can play a primary role in the etiology of this syndrome. Therefore, the aim of this review is to analyze the recent advances achieved regarding the bio-ecology of the endemic and emerging pathogens that threaten cork oak trees with particular emphasis on the species more directly involved in oak decline. Moreover, the effect of climate change on the host-pathogen interactions, a task fundamental for making useful decisions and managing cork oak forests properly, is considered.

“…A higher efficacy was not achieved probably because of the short time between fungicide injection and inoculation with D. corticola which could have reduced the uniformity in distribution of these fungicides in xylem, thus hampering the efficacy. On the debarked cork oak trees and under moist conditions, the canker length caused by D. corticola is reduced for 25.8-98.5% by preventive spray applications of thiophanate-methyl and/or copper-calcium sulphate, delivered immediately after the cork peeling [20]. On average, across different test locations, Bot canker control in this study was 64.7% with thiophanate-methyl and/or copper-calcium sulphate [20].…”

“…Agricultural, urban, and natural tree stands have been the focus of extensive plant pathogen diagnostic and disease management research in recent decades [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] which recorded an increase in the number of new fungal and bacterial pathogens and their detrimental impact on agroecosystems, ecosystems, and the human society. The economic effects of these pathogens are reflected in lost fresh fruit produce [17][18][19], reduced yields and quality of fruit or wood and cork products [20,21], diminished ecological tree services, and death of whole trees, stands, and forest regions or decimation of fruit industries [19,22].…”

With the challenges that negatively impact tree-based agriculture, landscapes and forests, such as climate change, plant pathogen and insect range expansion, invasive species and limited new pesticides, it is important to introduce new and effective tree protection options. In the last 20 years, pathogens that invade wood i.e. vascular tissues of trees causing wilt, yellowing, premature defoliation, cankers and tree death, have been on the rise. Diplodia corticola causes Bot canker of oak species which can kill trees diminishing the valuable ecological services they provide and reducing profits from wood and cork production. Since this and similar pathogens have difficult biologies because they reside in wood and cause severe internal damage and tree death, their management is difficult or inefficient with classical pesticide application methods that cannot reach and distribute the active ingredient in vascular wood tissues. As practical management options for this and other vascular tissue pathogens of trees are limited, we evaluated efficacy of several trunk injected fungicides in control of D. corticola and compared it with the efficacy of trunk injection of similar compounds for control of Venturia inaequalis and Erwinia amylovora, as two well-studied apple tree pathogens with different or partially similar lifestyles to D. corticola, respectively.

“…corticola has emerged as an aggressive and potentially invasive fungal pathogen in southern Europe, North Africa, and North America [18,[56][57][58]. The frequency of its attacks on oak trees has significantly increased over the past decades, especially in mature cork oak forests after cork extraction [59,60]. Diplodia corticola is a necrotrophic pathogen whose infections induce extensive inner bark and xylem necrosis associated with blackish exudation from the outer bark [61].…”

The black-banded oak borer, Coraebus florentinus, is an emerging pest of oak trees in the western Mediterranean region. Larvae of the insect are xylophagous and progressively excavate an annular gallery that interrupts sap flow, resulting in the death of the attacked branches. Until now, limited information has been available regarding the ecological interactions between C. florentinus and the main plant pathogenic fungi involved in the etiology of oak decline. Knowledge of these interactions is important in understanding their impact in natural ecosystems and developing appropriate management strategies. Therefore, in this study, we characterized the fungal communities occurring in the exoskeleton of adults and larvae of C. florentinus and associated with the necrotic wood tissues surrounding the branch galleries of declining oak trees. A total of 29 fungal species were identified based on DNA sequence data and morphological features, of which 14 were from symptomatic woody tissues, six from insect exoskeleton, and nine from both insects and symptomatic wood tissues. The most frequent fungal species, Cryphonectria naterciae (15.9% of isolates), Dothiorella iberica (11.3%), and Diplodia corticola (9.9%), were isolated from both insect and gallery systems. All three species are well-known oak pathogens and are reported here, for the first time, to be associated with C. florentinus. At the same time, 89.6% of the fungal taxa were isolated from one or two sites, highlighting the site-dependence of fungal community assemblages.
