Are Farm to fork strategy goals reasonable and achievable? State of the art of Península de Setubal’s winegrowers

Abstract

The European Union’s “farm to fork” strategy sets out several objectives to be achieved by farmers, who, among others, relate to increasing biodiversity, protecting soils and reducing the use of pesticides. At a time when the amendments to the national plans of Sustainable Use of pesticides are being discussed, it is important to understand what the Setúbal Peninsula region status is. Today, the main challenges for farmers are the impact of pesticides on public health, environmental protection, waste reduction, bees and non-target organisms’ protection, the removal of many active ingredients and climate change. Faced with these challenges, the use of pesticides in 235 winegrowers in the Palmela region was evaluated between 2016 and 2021. To support some of the answers, a socio-economic survey was also carried out. The data analyzed included the number of treatments, the dosages used, compliance with the pre-harvest interval, the reason why winegrowers performed phytosanitary treatment and how they chose a pesticide. For each year, it was found that, on average, farmers spray seven times, although the trend was to decrease. The most used pesticides belong to groups 3 (Triazol), M02 (Inorganic) and M04 + 4 (Ftalimidas + Phenyl Amids), according to the FRAC Codes. Regardless of the climatic conditions and the pressure of the disease in the vineyard, winegrowers sprayed every 14 days. These data were also related to climatic conditions, the existence of technical assistance and socio-economic data.
In addition to the analysis of the records and the interpretation of their relationship with the other data referred to above, residue analyses were carried out at the entrance of the grapes into the winery to assess whether the MRL was exceeded and whether were not authorized pesticides were used in the vine. This procedure was repeated in 2019, 2020 and 2021. The discussion around waste has been very intense in civil society. If, on the one hand, pesticides are indispensable to agricultural production, it is also true that their use must always take into account food security and environmental protection. It is important that the message is clear, transparent and assertive and that the consumer is also interested, critical and understandable. The second reason for the analysis of waste is related to the withdrawal of active substances and the existence of alternatives for farmers. In field trials, it has been noticed that the so-called “biological alternatives” are sufficient in situations of low/medium pressure of disease, but inefficient in medium/high pressure situations. By analysing data from plant protection records and waste analysis, it was concluded that fear of diseases and pests and “empirical experience” sometimes go beyond knowledge and technology. In addition, the weak valorisation of grapes and discouragement with the implementation of some poorly reported strategies are factors that fuel the concern about the difficulty in achieving the goals.

An excessive leaf-fruit ratio reduces the yeast assimilable nitrogen in the must

Yeast assimilable nitrogen (YAN) in the grape must is a key variable for wine quality as a source of aroma precursors. In a situation of YAN deficiency, a foliar urea application upon the vine at veraison enhances YAN concentration and facilitates must fermentation. In 2013, Agroscope investigated the impact of leaf-fruit ratio on the nitrogen (N) assimilation and partitioning in grapevine Vitis vinifera cv. Chasselas following foliar-urea application with the aim of improving its efficiency on the YAN concentration.

Extraction of polyphenols from grape marc by supercritical fluid extraction (SFE) and evaluation of their ‘bioavailability’ as dietary supplements

In the winemaking process, several compounds that remain in the grape skins and seeds after the fermentation stage are bioactive-compounds (substances with potential beneficial effects on health) that can be extracted in order to recovery valuable substances with a high commercial value for the cosmetic, food (nutraceuticals) and pharmaceutical industries. The skins contain significant amounts of bioactive substances such as tannins (16-27%) and other polyphenolic compounds (2-6.5%) in particular, catechins, anthocyanins, proanthocyanins, quercetin , ellagic acid and resveratrol.

The impacts of frozen material-other-than-grapes (MOG) on aroma compounds of red wine varieties

An undesirable note called “floral taint” has been observed in red wines by winemakers in the Niagara region caused by large volumes of frozen leaves and petioles [materials-other-than-grapes (MOG)] introduced during mechanical harvest and subsequent winemaking late in the season. The volatiles, which we hypothesized are responsible, are primarily terpenes, norisoprenoids, and specific esters in frozen leaves and petioles. The purpose of this study was to investigate the volatile compounds which may cause the floral taint problem and explore how much of them (thresholds) may lead to the problem. Also, the glycosidic precursors of some of these compounds were analyzed to see the changes happening during frost events.

Aromatic profile of six different clones of Chardonnay grape berries in Minas Gerais (Brazil)

Aromas are one of the key points in food analysis since they are related to character, quality and consequently consumer acceptance. It is not different in the winery industry, where the aromatic profile is a combination of viticultural and oenological practices. Based on the development of more aromatic clones and on the potential to produce sparkling wines at Caldas, in the southern region of Minas Gerais (Brazil) (21°55´S and 46°23´W, altitude 1,100m), the aim of this work was the determination of volatile compounds in six different clones of Chardonnay grape berries to better understand which compounds add bouquet to the wine, and additionally comprehend the impacts of the edaphoclimatic and annual conditions on the improvement of grape-growing and winemaking practices.

Improving stilbenes in vitis Labrusca L. Grapes through methyl jasmonate applications

Grapes (Vitis sp.) are considered a major source of phenolic compounds such as flavonols, anthocyanins and stilbenes. Studies related to the beneficial effects of these compounds on health have encouraged research aimed at increasing their concentration in fruits. On this behalf, several plant growth regulators such as jasmonic acid and its volatile ester, methyl-jasmonate (MeJa), have demonstrated promising results in many fruits. However, Brazilian subtropical climate might interfere on treatment response. The present study aims to evaluate the application of MeJa in the pre-harvest period in Concord and Isabel Precoce grapes (Vitis labrusca L.).
