Monitoring damage of gipsy moth by using remote sensing technique in counties Veszprém, Somogy and Nógrád during 2005
(Dr. György Csóka, Gizella Nádor)
The article reflects the possibilities of remote sensing in the detection of gipsy moth damages by using novel, medium-resolution satellite imagery. It is a rapid and effective tool compared to the conventional survey requiring immense field work. Damage maps derived from satellite imagery of counties Veszprém, Somogy and Nógrád, shown here in colour pictures, were compared pixel-by-pixel to the map of feeding damage by the pest, prepared by the State Forest Service and the Hungarian Forest Research Institute. The comparison shows a fair matching between the imageries deriving from two independent sources. Therefore it can be concluded that medium-resolution satellite imagery technique is suitable for monitoring damage by the pest.

Studying high increase of population density of gipsy moth in county Veszprém
(Krisztina Nagy)
The author gives an account of the experience of the Plant Protection and Soil Conservation Service of County Veszprém about the spread of gipsy moth in the forests, agricultural lands and home gardens throughout the county. In addition, she mentions the means of control applied in municipal public areas (roadside trees, ornamental trees, parks) in 2005 and the possible causes of the decrease of the recently high gipsy moth populations.

Lessons learned for practice from gipsy moth “boom” in 2003-2005 at Bakonyerdő Co.
(Zoltán Stubán
The forests of Bakonyerdő Co., due to the large forest areas and the concentrated presence of host plants (Turkey oak, pedunculate /English/ oak), are optimal places for gipsy moth, one of the most dangerous pests of our forests. Therefore forestry professionals monitor gipsy moth population dynamics based on counting egg masses in autumn. They have been sharing their observations with our readers since 2003, when mass reproduction of the moth began. They give a detailed discussion of the applied control methods and summarise their experience obtained in the past three years.

Seen, heard, read. Meeting about gipsy moth control
(Dr. Gábor Princzinger)
The article reports on a meeting, titled “Gipsy moth is round the corner again”, held on 4 May 2006. The event, organized by the Forest Protection Department of the Hungarian Forest Research Institute, the Forest Protection Section of the Hungarian Forestry Association and the Hungarian subsidiary of Crompton Europe Ltd. provided a forum for discussing last year’s high population densities of the pest and the jobs to be done this season.


Winter barley infections by powdery mildew and net blotch (Pyrenophora teres) in 2003-2005
(Dr. András Palágyi, Dr. András Tomcsányi)
The authors compared the three years’ results of resistance trials with winter barley varieties included in the national list by completing disease data of experiments conducted by the National Institute for Agricultural Quality Control in 2005 with the results obtained in the two previous years. The early and mid-season varieties were evaluated for resistance to powdery mildew (Erysiphe graminis) and net blotch (Drechslera teres), annually and in the average of three years. The results are shown in tables.

What was the reason of free fatty acid (FFA) increase in sunflower?
(Zoltán Papp)
It is a widespread opinion that the high free fatty acid (FFA) values of sunflower could only be attributed to white rot (Sclerotinia sclerotiorum). The article, intending to launch a debate, informs on studies where, in addition to the disease, other factors may also be among the causes. Year 2005 was conspicuous not only for the severe white rot of sunflower heads but there were big problems also with FFA after harvesting. The FFA value of the produce was by 25.5% higher on an average than the maximum limit (2 %). The objective of the author and his colleagues was to find out the reason why enzyme activity increased and oxidation processes accelerated, involving the increase of FFA. In the light of this, they evaluated the following issues: disease incidence by Sclerotinia sclerotiorum and Botrytis cinerea, chemical treatments, varieties, desiccation, sowing date, saprophyte and parasitic pathogens colonizing the seed surfaces, harvesting dates, as well as the conditions of harvesting, transport, desiccation and the effect of weather conditions during those times on the changes of FFA content.

About damages affecting crop quality of sunflowers in 2005
(Mihály Perczel)
The author reviews the damages in 2005 affecting sunflowers regarding crop quantity (lodging, fall-off, falling down of rotten heads to the ground) and crop quality (decrease in protein content of sunflower groats and the increase of free fatty acid content of the oil). The author explains the latter with the increased lipase enzyme activity in the achenes.

PIONEER – focusing on the grower (x)
(Dr. László Piukovics, Péter Sipos)

Taking care of lawns and turfs
(József Szendrői)
The share of lawns and turfs reaches 60-70 % of the public green areas in the particular localities. In most of the cases, the gardens of the institutions, the areas of open-air baths and home gardens are covered with lawns and turfs, not to speak of the “evergreen” sports grounds and golf-courses. The horticulturist author draws the attention to the techniques that, if applied professionally, allow advanced-level maintenance of lawns and turfs (mowing, nutrient supply, aeration, disease control, prevention of weed- and moss infestation). In addition, we may get to know the difference between lawns and turfs, as well as the causes of the various intermediate “grasses” in practice.

Reforming pesticide registration from the point of view of the industry
(Dr. Ferenc Hargitai)
The article is a contribution to the paper of dr. Gábor Tőkés, published in our number of March 2006, discussing the main elements of the planned system of pesticide registration in the European Union. On behalf of the Hungarian Plant Protection Association, the author points out that they agree with the technical conclusions of the referred article. The pesticide industry and the Hungarian and international business federations consider the same ones as decisive among the planned changes. He stresses that a joint and more definite intervention is possible only by recognizing common interests. Based on industry experience and completing the article of dr. Tőkés, the author of the present paper casts light on the problems of the main elements of the new system (termination of temporary registration, introduction of the zone-system, the effect of mandatory sharing of data on small crops and the operation of the substitution system).

Studies on nectar production of certain sunflower hybrids
(Edit Zajácz)
The Research Institute for Animal Breeding and Nutrition carried out trials to determine the apiarian value and bee visiting characteristics of certain sunflower hybrids in a particular area for various years. In the paper the author gives an account of their study conducted in summer 2005, comparing nectar production, nectar sugar content, and sugar value of 8 hybrids in the average of 6 days. The author, specialist of the research institute points out that when choosing sunflower hybrids to be grown, in addition to economic values, their apiarian value is also worthy of attention in order to achieve safer fertilisation and by that, higher yields.


Sprayer nozzles and tips (1)
(Dr. György Dimitrievics)
The efficacy of spraying is primarily determined by the applied nozzles and tips. Therefore, users need to know their structure, the key factors determining their operation and the basic requirements of their application to achieve successful control. The spray has to be applied at the required volume, with high accuracy, producing proper droplet size and ensuring the most even distribution possible on the target surface. Nozzles and tips of various systems and design have been developed to meet these requirements that are outlined here by a specialist of the Hungarian Institute of Agricultural Engineering.
