Abstract(s)
Grapevine is regarded as a highly profitable culture, being well spread
worldwide and mostly directed to the wine-producing industry. Practices to
maintain the vineyard in healthy conditions are tenuous and are exacerbated
due to abiotic and biotic stresses, where fungal grapevine trunk diseases
(GTDs) play a major role. The abolishment of chemical treatments and
the intensification of several management practices led to an uprise in
GTD outbreaks. Symptomatology of GTDs is very similar among diseases,
leading to underdevelopment of the vines and death in extreme scenarios.
Disease progression is widely affected by biotic and abiotic factors, and the
prevalence of the pathogens varies with country and region. In this review,
the state-of-the-art regarding identification and detection of GTDs is vastly
analyzed. Methods and protocols used for the identification of GTDs, which
are currently rather limited, are highlighted. The main conclusion is the utter
need for the development of new technologies to easily and precisely detect
the presence of the pathogens related to GTDs, allowing to readily take
phytosanitary measures and/or proceed to plant removal in order to establish
better vineyard management practices. Moreover, new practices and methods
of detection, identification, and quantification of infectious material would
allow imposing greater control on nurseries and plant exportation, limiting
the movement of infected vines and thus avoiding the propagation of fungal
inoculum throughout wine regions
