The impact of vineyard agrochemicals against a phytophagous mite and its predator

By Darliane Evangelho Silva, Joseane Moreira do Nascimento and Noeli Juarez Ferla
Winemakers use agrochemicals to control grapevines diseases and pests. Panonychus ulmi is a spider mite that causes damage to grapevines in the South of Brazil, whereas Neoseiulus californicus is the most frequently used predatory mite in biological control of tetranychids in Brazil. This post describes a study recently published in which 13 agrochemicals used in the wine growing sector and their effect on P. ulmi and N. californicus were evaluated. With the results of this study will be possible to define guidelines about the best products to be used in the field and to create pest management practices that preserves predatory mite populations in vineyards.

Irrigation for modulating Godello wine composition under humid conditions

By José Manuel Mirás-Avalos, Yolanda Bouzas-Cid, Emiliano Trigo-Córdoba, Ignacio Orriols and Elena Falqué

In many viticulture regions the need of vineyard irrigation has been discussed. Before this practice could be implemented is necessary to carry out research to evaluate the effects in wine quality. This post reports the results of a study that assessed the amino acid profile of musts and wines, volatile composition and sensory profile of wines from Vitis vinifera (L.) cultivar Godello under rain-fed and two drip irrigation systems over three consecutive years. The authors concluded that weather conditions affected more must and wine composition than in-season effects caused by irrigation.

Lasers, nanoparticles and wine: white wine identification with SERS

By Alois Bonifacio
Wine counterfeiting is a concerning problem. Several strategies were developed to solve this problem. In this post is described the application of label-free SERS spectroscopy as an analytical technique for white wine characterization. This approach was tested in 180 samples of three white wines varieties from northeastern Italy. The results of this study show that SERS could be a good method to identify wine. Find out more
