“…Important pruning practices include limiting the number and size of clean cuts in order to help reduce the susceptibility of the cordon to fungal trunk disease infection, as well as avoiding pruning during wet conditions when spore inoculum is prevalent [101]. It has been suggested that training methods involving minimal pruning show less esca disease effect than methods involving regular manual pruning [102], and techniques which concentrate pruning wounds on the crown of the vine should be avoided, particularly for cultivars sensitive to wood disease. Recent research has indicated that the total surface area of cuts on a cordon rather than the diameter of each cut is the more important factor in regard to incidence of Eutypa dieback [103].…”

Decisions made during the establishment and reworking of permanent cordon arms may have long-term consequences on vineyard health and longevity. This review aims to summarise several of the important considerations that must be taken into account during cordon establishment and maintenance. Commonly practiced cordon training techniques such as wrapping developing arms tightly around the cordon wire may result in a constriction of the vascular system, becoming worse over time and disrupting the normal flow of water and nutrients. Studies have shown that other factors of cordon decline such as the onset of vascular diseases may be influenced by pre-existing stress conditions. Such conditions could be further exacerbated by water and heat stress events, an important consideration as these scenarios become more common under the influence of climate change. Vineyard sustainability may be improved by adopting cordon training techniques which promote long-term vitality and avoid a reduction in vine defence response and the costly, premature reworking of vines.

Dieback diseases are caused by Fomitiporia and Botryosphaeria two genus of fungi that colonize wood tissue in grapevine. After the prohibition of sodium arsenite in 2001, no chemical treatments are available to control these diseases. Curettage is a possible substitute solution. The results depend on many factors. The use of essential oils can be an alternative and/or complementary way. This study aims to investigate the essential oil (EO) composition of Eucalyptus globulus (E. globulus) from leaves and flowers and to evaluate its antifungal activity against Botryosphaeria dothidae and Fomitiporia mediterranea fungi. GC–MS results show that 97.79% of oil composition was identified, of which the Eucalyptol is the major compound (76.33%). Other compounds were identified such as α-Pinene (9.81%); Allo-Aromadendrene (3.07%) and Limonene (2.55%). EO had a detrimental effect in vito on both developed Botryosphaeria dothidae and Fomitiporia mediterranea fungi. The effect is dose-dependent and increases with the duration of the treatment. Essential oil concentrations of 0.25% and 0.75% of E. globulus were efficient against Botryosphaeria dothidae and Fomitiporia mediterranea, respectively. This is the first report investigate the purpose of E. globulus EO to control this both phytopathogenic fungi. The results from the antifungal assays reveal that EO of E. globulus has an excellent inhibitory effect against both tested fungi.
