2005 – the year of expectations and unfulfilled hopes in the grape and wine sector
The National Council of Vine-growing Communities takes into account the most important events for vine growing and winemaking. The article gives an account of the favourable and adverse effects, wine stocks and the crop, as well as outlines the changes in the legislation relating to vine growers and winemakers.
The role of new varieties in vine growing
(György Pernesz, Eszter Balikó)
The article begins with the brief history of grapevine breeding in Hungary. The authors believe that breeding work can be considered successful if the produced variety has favourable traits for the grower and is placed on the list of national varieties. Therefore the authors present the success of breeding by dealing with the particular red and white wine and table grape varieties included in the national list for their share in propagation material production. Finally, giving a background for this, they consider the factors that affect the nursery propagation of new varieties and their planting by growers.
Integrated control of grapevine diseases
In the frame of sustainable development, integrated production is a system based on forecasting of pests and diseases, their prevention and reasonable control respecting the interests of the environment, nature and consumers at the same time. First, the article gives a summary of the principles of the integrated plantation target program under the National Rural Development Plan (NVT), aiming at the reduction of environmental load from pesticide and fertilizer use. In the light of this, the author presents the main criteria of pest management both before planting and in the bearing vineyard. She deals with the importance of cultural techniques, the forecasting of diseases and control strategy. She outlines the major diseases of grapes (powdery mildew, downy mildew, grey mould, leaf scorch, white and black rots), describes their symptoms, the mode of overwintering, environmental conditions conducive to infection, susceptible growth stages of the crop, thus indicating the timing of treatments.
Grapevine diseases and their symptoms
The brief article helps growers recognize the most important diseases in vineyards (powdery mildew, downy mildew, grey mould, leaf scorch, white and black rots). It includes the description of the complex of symptoms appearing on the particular plant parts, illustrated with colour pictures.
Experience with grapevine diseases in 2005 in vineyards in the district of Balatonboglár
The professional of Boglár Doctors of Plant Medicine Ltd. clearly points out the critical situation of the Hungarian grapevine sector. He is of the opinion that cost-efficient vine growing can be achieved only by implementing integrated production in the frame of the support system for agro-environment management. This is why every vine grower should be aware of the conditions of the system regarding both chemicals use and other regulations. The author gives an account of last year’s experience with the control of downy and powdery mildews, grey mould and grapevine decline in the district of Balatonboglár.
Two new products for protecting grapes (x)
Dow AgroSciences draws vine growers’ attention to Systhane 12 E (myclobutanil) and Kristály IQ (quinoxyfen) for powdery mildew control.
Grey mould damages in 2005
Seeking the causes of the severe damages by grey mould in 2005, the author draws the attention to the mistakes made in the pest management programme that increased the problems given by the rainy weather conditions favouring the diseases. The shortcomings are dealt with in three groups such as plant protection, nutrient supply and cultural operations in the crop.
Experiences with plant protection forecasting in 2005
The forecasting system called AGROEXPERT has been used in the district of Sopron in the wine-region of Sopron since 1998. The article gives a brief account of the experience in running the system in 2005; informing on the successful forecasts of AGROEXPERT. Furthermore, it also points out the obstacles for growers in really efficiently using the forecasting information.
Melody Compact, the new element in Bayer’s pest management programme (x)
Bayer CropScience recommends growers Melody Compact (iprovalicarb +copper-oxychloride) for downy mildew control in vineyards.
Environmentally friendly, integrated control of grapevine pests
The author begins with presenting the primary conditions of environmentally friendly integrated protection of grapes. According to this, integrated management programme is based on the forecasting of pests, and chemical treatments shall be carried out to complete other means of control, such as agronomic, mechanical, biological and biochemical methods, taking economic threshold values into account. It is followed by outlining the methods of predicting the likely damage and the possibilities for agronomic, biological and chemical control of leaf rust mite, vine leaf blister mite, European red mite and grape moths in the integrated production of grapes.
Things we should pay attention to when spraying
(Dr. György Dimitrievits)
In vine growing, the success of treatments, besides the efficacy of the used chemicals and other factors, highly depends on the design of sprayers and the conditions of operation. Improper operation of the machines leads to uneven spray distribution with over- and under-sprayed surfaces, and a considerable part of the liquid may deposit on the ground or drift. The specialist of the Hungarian Institute of Agricultural Engineering summarizes the aspects other than machine characteristics that require special attention during spraying in vineyards. The article also includes the results of comparative tests of chemicals distribution and the amount of losses when using machines with the particular spraying devices and fan capacities.

Concentration of area rate? (2.)
(Dániel Mukli, Péter Fülöp)
The authors give an account of their results and the conclusions of their trials aimed at finding the answer to the question whether it is always reasonable to follow manufacturers’ recommendation for area rates of pesticides in grapes.
About the benefits of using the special surfactant Silwet L-77 (x)
The development engineer of Crompton Europe Ltd. shares his opinion with readers about the reason why it is worth using the surfactant Silwet L-77 for pest management in orchards and vineyards.

You may have an insight into Hungarian Kwizda’s programme of “Supplying nutrients and Protecting” regarding vine growing.
What is your opinion about the present and future of vine growing: Éva Keresztury (Hilltop Neszmély), Attila Gere (Villány), István Mikóczy (Tata)? Report
(Dániel Mukli, Diána Mészáros Pólya)
The article reports on the talks with recognized winemakers and vine growers about the present situation of Hungarian vine growing and future plans and prospects.
Thoughts in connection with the wine containers of up-to-date wineries
The article lets us have an insight into the global trends in winemaking and wine tastes and their consequences in changing the containers used for storing wines. The author outlines the criteria of traditional wine storing in wooden casks, and the basic requirements of using and storing casks. The article finishes with presenting the major characteristics and advantages of the current storing of wines in metal tanks.

Possibilities for using cosmic time for timing vintage
As the author expresses it, similarly to the planets revolving on their orbits, everything existing around us has a rhythm: grasses and trees also grow according to it. We may find the secret of life in every plant, also in grapes. We should get to know it. So that we could do it, we need to think about other ways of living, other ways of thinking and about accepting another biorhythm.
