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
(Ágnes Schmidt)
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

Experience with grapevine diseases in 2005 in vineyards in the district of Balatonboglár
(Szabolcs Makó)
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.

(Gabriella Szendrey)
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.

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.
