Evaluation of grapevine rootstocks against soilborne pathogens associated with trunk diseases

Acta Horticulturae, 2016
[EN] The susceptibility of the grapevine rootstocks most commonly used in Spain to black-foot (Ilyonectria liriodendri and Dactylonectria macrodidyma-complex) and petri disease (Cadophora luteo-olivacea, Phaeomoniella chlamydospora and five species of Phaeoacremonium) pathogens was evaluated.

El ácido abscísico y metil jasmonato modulan la acumulación de antocianinas y trans-resveratrol en hollejos de bayas de cinco cultivares tintos de Vitis vinifera en dos regiones vitícolas contrastantes de Mendoza, Argentina [PDF]

, 2019
Los hollejos de las uvas tintas contienen cantidades significativas de polifenoles que contribuyen a la calidad del vino y proporcionan beneficios para la salud. Estos compuestos pueden ser elicitados por hormonas vegetales.

Fungal Trunk Diseases: A Global Threat to Grapevines

Annual Review of Phytopathology
Trunk diseases are global wood diseases of grapevine that can significantly reduce the productive lifespan of vineyards. Infection may initiate at the nursery or in vineyards. Grapevine trunk diseases (GTDs) are caused by diverse Ascomycota and Basidiomycota fungal pathogens in at least nine families. They may be soilborne or airborne, depending on the

Potential use of chitosan in the control of grapevine trunk diseases

Phytopathologia Mediterranea, 2007
Due to its fungistatic or fungicidal potential, chitosan, a high molecular-weight polymer that is non-toxic and biodegradable, has become an alternative to conventional fungicides. In addition, chitosan is reported to elicit defense mechanisms in plant tissues.

Evaluation of a trunk injection technique to control grapevine wood diseases

Phytopathologia Mediterranea, 2007
Vineyard experiments were conducted over five years in the Bordeaux area to evaluate the effectiveness of trunk injections in controlling Eutypa dieback (4 trials) and esca (1 trial). Single treatments were applied in winter 2001 or 2002 using the tree injector StemJect®.

Biosolutions from Native Trichoderma Strains Against Grapevine Trunk Diseases

Agronomy
Fungi of the genus Trichoderma show strong potential as biological control agents (BCAs) against grapevine trunk diseases (GTDs) through mechanisms like antibiotic metabolite production and lytic enzymes. This study evaluated the biocontrol activity of four native Trichoderma strains—T. gamsii T065 and T071, T. carraovejensis T154, and T.

Effective Control of Neofusicoccum parvum in Grapevines: Combining Trichoderma spp. with Chemical Fungicides

Agronomy
Vitis vinifera is highly susceptible to grapevine trunk diseases, with Neofusicoccum parvum recognized as a highly destructive pathogen. This study investigates the biocontrol potential of five Trichoderma species (T. harzianum, T. viride, T. asperellum,

Detection of grapevine leaf stripe disease symptoms by hyperspectral sensor

Phytopathologia Mediterranea, 2018
Hyperspectral sensors can measure reflectance in a wide range of the electromagnetic spectrum. These can be used as an indirect method for detecting plant disease, by comparing the specific spectral signatures between symptomatic and asymptomatic ...
