Nepenthe – or chasing away sorrow

New grapevine varieties and clones on the national list
(György Pernesz)
Last year the choice of our table and wine grape varieties were enriched by various varieties and clones. The article describes the origin, the most important morphological characteristics and the production values of the particular varieties.

Parent-progeny relations among our grapevine varieties
(Péter Bodor, Zsuzsanna Varga)
The grape varieties enter into commercial growing as the outcome of selection or crossing. This article wishes to present the results of national and international investigations concerning the origin of hybrids. The varieties involved in growing via selection, i.e. were created by a mutation of a plant (e.g. bud mutation) are not covered by this article.

Evaluating grapevine rootstocks – accommodating to site conditions
(Anna Csikász Krizsics)
Rootstocks can significantly modify the production value of the variety, expressed in particular in the vigour of the vine, the longevity of the vineyard and the crop quantity. The effect on quality is less measurable, it acts more indirectly. This article lets us have an insight into the experiments with the combinations of Cabernet sauvignon established by the Research Institute of Viticulture and Oenology of Pécs University.

Suitability of different soil management methods on areas exposed to erosion
(Dr. Péter Varga, Dr. János Májer, Csaba Németh)
The authors present the results for 2007-2008 of their soil cover trial. Among the tillage operations available for use in integrated vine production, the investigators studied, in addition to soil cover by organic waste, the effects of lasting and temporary soil cover on the development of vine plants, yields, nutrient content of the soil and leaves, the moisture content and compactness of the soil in a vineyard planted on a site with an average slope of 10-12 %.

Quality vine-growing and low crop load
(Dr. Gábor Zanathy, István Fazekas)
There are strict requirements and legislation specifying yields and the number of viable buds left on the vine. In case of low crop load fruit quality can be fairly good, but excessively reducing the number of buds can easily lead to breaking the bearing balance of the vine, expressed in too vigorous shoot growth. Therefore it is worth briefly considering the factors influencing vigour of grapevine and clarifying the various effects of reducing crop load.

Requirements of organic grapevine growing and the system to control and certify their fulfilment
(Judit Göblyös)
A great many people speak about ecological growing but what do we mean by that? Which are the main requirements that one needs to meet during ecological production, in particular in terms of plant protection, nutrient supply, weed control and soil cultivation? What is the period of time available for transition to ecological growing, furthermore, how does the control and certification scheme work? The article will give the answer to all these questions.

Tools to help pruning
(István Fazekas, Dr. Gábor Zanathy)
Pruning is a very labour-intensive operation, therefore trying and introducing technologies facilitating and replacing hand pruning is gaining more and more importance. This is why the authors from Budapest Corvinus University guide readers to the world of pneumatic and electric pruning scissors and of mechanical pre-pruning.


Susceptibility of grapevine varieties to powdery mildew
(Dr. Edit Hajdu)
Last year growers were fighting against a threatening fungal disease of grapes, powdery mildew throughout the country. They encountered infections impossible to control in various wine-regions. Many times, thorough knowledge of the varieties or the process of the disease for basing practical plant protection is often missing. This is why we publish the experience of the investigators in the Research Institute for Viticulture and Oenology obtained in 2008 with the susceptibility of grape varieties to support more efficient control of powdery mildew.

About resistance, a bit differently (x)
(Dr. Antal Kürti, Dr. Elemér Tóth)
DuPont presents its fungicide offer to fight powdery mildew and downy mildew of grapes.

What has happened in Szekszárd vineyards since the emergency? Report
(Zsuzsanna Györök)
The author talked with dr. Géza Vörös, head of the Directorate of Plant Protection and Soil Conservation of the Agricultural Office of County about the experience of vintage obtained last year in Szekszárd wine–region and the pest management situation in vineyards after the withdrawal of many pesticides from the market planned by the EU.

Pergado F – Long-life and safe protection (x)
(Éva Nádudvari)
Syngenta Kft. recommends growers its fungicide Pergado F (mandipropamid +folpet) to control downy mildew in vineyards.

Conclusions of grapevine powdery mildew in 2008
(János Czink, Attila Hollósi, Mihály Kovács, Diána Mészáros Pólya, József Mikonya, László Somogyi)
Some plant protection professional working at different wine-regions of the country summarise their experience about powdery mildew. It turns out from the article whether professionals were able to protect their vineyards from the disease, which were the active substances and products found efficient in the control and how they are preparing for fighting the pathogen in the forthcoming pest management season.

Technology of spraying in vineyards
(Dr. György Dimitrievits)
Efficient pest management is a precondition of successful vine-growing. The applied sprayer and the level of operation also play an important part in the success of the control. Therefore it is important to take into account the technical conditions such as selecting and operating the machines.

Weed control options in vineyards
(Attila Hornyák)
The article summarises the criteria and jobs to consider for achieving successful weed control in vineyards before and during planting, the major weeds in vineyards, as well as the mechanical, agronomic and chemical means of control.


A new scheme for wine categories. Report
(Miklós Kurucz)
The European Union will create a completely new basis for the protection of origin of wines and the related indications and marking from 1 August 2009. This will give a new task for every winery, but information provided to consumers will also be basically changed. We asked Csaba Horváth, the secretary general of the National Council of Vine-growing Communities in order to be informed about the most important criteria and understand.
