“…According to the last viticultural report, the grapevine varieties most cultivated in Chile for wine production are Cabernet‐Sauvignon (41 156 ha), Sauvignon Blanc (15 162 ha), Merlot (11 703 ha), Chardonnay (11 297 ha), and Carmenère (10 250 ha), whereas the least cultivated grapevine varieties for this same purpose are Gros Colman (0.35 ha), Ahmeur Bou Ahmeur (0.30 ha), Moscatel Rosada (0.25 ha), Gros Manseng (0.04 ha), and Muscat à Petits Grains (0.02 ha) . It is also important to consider that phylloxera is distributed in most major viticultural regions with the exception of Chile and the Australian states of South Australia and Western Australia …”

Resurgence of minority and autochthonous grapevine varieties in South America: a review of their oenological potential

In contrast with the general trend of producing wine from the most famous grapevine varieties, associated with the French paradigm, such as Cabernet‐Sauvignon, Merlot, Pinot Noir, Syrah, Sauvignon Blanc, and Chardonnay, there is a tendency to revalorize and preserve minority or autochthonous grapevine varieties worldwide. The South American wine region, where most of the varieties derived from varieties brought after European colonization, is not exempt from this. This has allowed new wines to be provided with distinctive identities that are markedly different from the current homogeneous wine production. Moreover, varietal homogenization increases vineyard genetic vulnerability in relation to the emergence of grapevine diseases, to which the commonly cultivated varieties are not resistant. This review summarizes the oenological potential of minority or autochthonous grapevine varieties cultivated within the South American wine region, focusing on Argentina, Chile, and Bolivia. © 2019 Society of Chemical Industry

“…These traps consist of 3 to 5 L translucent plastic bowls, inverted and placed 10 cm from the sample vine trunk (10 to 20 sample vines are recommended per treatment). Traps should be secured adjacent to vine trunks with three metal tent pegs (Powell et al 2009). Traps are rinsed with tap water prior to placement to provide a film of condensate, which effectively traps emerging phylloxera dispersive life-stages.…”

Grape phylloxera biotypes are defined by their specific performance on, or preference for, a particular host (e.g., feeding on a particular rootstock). Numerous studies have phenotyped phylloxera biotypes, particularly with regard to their performance on various hosts, but the results are difficult to compare because there is neither a homogenous nomenclature nor a standardized protocol for phenotyping. To improve communication within the scientific community, we offer a simplified phylloxera biotype classification to allow clear data interpretation and effective communication. We also introduce the standard techniques employed for phylloxera phenotyping and discuss their advantages and disadvantages.

“…Vineyard managers are already encouraged to collect EM38 data for other aspects of grapevine production, so there should be little increased cost . Several new methods for early phylloxera detection are currently being developed and trialled, including chemical and pigment fingerprinting of metabolites as biomarkers in leaves, a phylloxera‐specific DNA probe, emergence traps and, more recently, the use of unmanned aerial vehicles and sniffer dogs . The efficiency of all these new methods has the potential to be improved by spatially targeted surveillance designs like those considered in this study.…”

Targeting surveillance strategies based on local-scale spatial heterogeneity can decrease the time to detection without increasing the survey cost, and surveillance that targets highly suitable soil is the most efficient strategy for detecting new incursions. In addition, combining targeted surveillance strategies with buffer zones and hygiene procedures, and updating surveillance strategies as additional species information becomes available, will further decrease the risk of pest spread. © 2018 Society of Chemical Industry.
