Experience in a newly planted vineyard (János Szekretár)

In autumn 2001 the author planted a vineyard of 10.1 hectares in the wine-growing region Szekszárd. The article summarises the experience obtained during the preparation of planting, cultural operations in the first and second year after planting, as well as the conclusions of plant protection in the vineyard.

Controlling epidemic diseases (Teréz Dula, Ágnes Schmidt)

Reasonable and environmentally friendly plant protection, in order to control viral, bacterial and fungal diseases threatening the life of grapevine plants, safety and quality of the crop, is a complex system. Its principle is: let’s use chemicals only there, only then, only that amount and only the ones which are the most favourable from environmental point of view, that are essential for cost efficient production! The most important and at the same time the most difficult task in the control of diseases is to prevent infection. The article gives a brief account of the key knowledge for controlling the three main diseases: powdery mildew, downy mildew and grey mould. The itemized conclusions summarize the main elements of successful protection of grapes.

Esca- and Petri-disease (Teréz Dula)

As early decline causes damages in the wine-growing regions all over the world without any exception, intensive studies have started for better understanding the disease. The most recent research methods highly contributed also to our knowledge about Esca- and Petri-diseases. The author gives an account of them. She presents the symptoms helping to recognise the diseases, the etiology of the disease and the currently available control methods.

Recent foreign and Hungarian results of research in early decline (Dr. József Mikulás, Dr. János Lázár, Szilveszter Morvai, Andrea Rábai)

Esca is a complex disease of grapes, it cannot be controlled without being aware of the role of the particular fungi in the disease and of the ones being decisive as causal agents. The authors studied international results and tested 13 samples showing esca symptoms taken in 8 wine-growing regions in the frame of a German-Hungarian cooperation.

Choice of products for grapevine protection

Fungicides registered for the control of grapevine fungal diseases are tabulated. The extremely useful and informative tables inform Readers on the major fungal diseases of grapes (downy mildew, powdery mildew and grey mould) and the plant protection products grouped according to their use, offering solutions for interested readers to choose the appropriate products.

Mites and grape moths (Gabriella Szendrey)

Around 200 pests are recorded as potential pests of grapes. Among them the most important ones are phytophagous mites and grape moths. The foliage of grapes is mostly affected by mites, while bunches are especially threatened by moths. In order to carry out successful control of mites and moths, growers need to know the biology of the pests, the possibilities of their control, the alternatives of forecasting and the methods of integrated pest management. The article is a good contribution to it.

Scale insects and phylloxera (Gabriella Szendrey)

The population density of scale insects in vineyards has also increased in the past few years. Among them the importance of mealybugs is even more significant as they are known as vectors of viruses and phytoplasmas. Grape phylloxera is a quarantine pest, therefore requires a continuous control in mother plantations and vineyards.

Fewer cleistothecia, lower risk of powdery mildew in the next season (x) (Dr. István Füzi)

BASF recommends its programme to manage grapevine powdery mildew.

The role of wash-off spraying in the integrated production of grapes (Gabriella Szendrey)

The advantage of was-off spraying in grapevine protection was a debated question for a long time. The efficacy and cost-efficiency of such treatments need to be revised in the light of the new circumstances. On the one hand, new products have been placed on the market, which can be used also out of dormancy, at budburst, woolly stage, even throughout the whole season. On the other hand, certain mixtures with synergic effect have become available. The author discusses overwintering issues of grapevine pests (stage and place of overwintering), then informs on the products to be used for washing-off.

The challenges of drought in the wine-growing region Villány (Diána Mészáros-Pólya)

It is a general belief that for grapevine, being a deep-rooting plant, water deficiency is not such a big problem as for herbaceous crops. However, experience of 2003 has shown that severe drought losses occurred in vineyards, especially with early cultivars. The article discusses the role of the particular elements of the crop production programme (tillage, cultural operations with the crop, nutrient and water supply, selecting the cultivars and irrigation) in managing drought.

Grapevine diseases and epidemics in the wine-growing region of Eger between 1993 and 2003 (Teréz Dula)

The effect of the more and more extreme weather conditions characteristic of the recent years can be seen also in the incidence and damage of the three grapevine diseases (powdery mildew, downy mildew and grey mould). Together with weather extremities, severe epidemics developed unexpectedly from “no sources” or expected infections did not come about from one year to another. The article gives a brief summary of such events.
