TOPIC OF THE MONTH

What is growers’ opinion about the agricultural situation?
(Dr. Lajos Gockler)
The article informs on the most important conclusions of the grower-response study conducted by the Research Institute for Agricultural Economics in 2005. Farmers define their position about preparing for the EU-accession, the investments of the holdings, the new subsidy system, agricultural employees, market prices, incomes, integration, structural changes, trading in agricultural produces, land property and use, as well as about the organisations representing the sector’s interest. The author finishes with his remarks on the survey.

TOPICALLY, UP-TO-DATE

We have asked
dr. Márta Birkás head of university department, what can or must do during the tillage works in fields affected by waterlogging?
Dr. Márta Birkás shares her opinion with growers about the establishment of surface ponding, how to enhance receding of water, how to tillage flooded fields, how to restore soil conditions and to prevent similar damages.

About adjuvants at the beginning of the spraying season (2)
(Dr. Péter Inczédy)
The author summarises the most important types of adjuvants that offer various solutions for protecting the environment and saving growers’ costs in addition to enhancing biological efficacy. It turns out from the article that a major group of adjuvants is composed of stickers, and the various oil-based substances have similar effects. The other main group is of surfactants reducing surface tension of liquids and thus improving the wetting of the treated leaf surface. Activators enrich the choice of adjuvants and we must not forget about antifoam and antidrift agents either. Commercial adjuvants are listed in a tabulated form.

Pest management in apples from bud burst to flowering
(Pál Sallai)
The author wishes to draw the attention to the potential risks encountered in apple pest management from bud burst to flowering, based on the experience of various growers during the past few years. The article summarises the issues that should be considered when shaping a successful plant protection strategy. The paper discusses leaf rollers, leaf feeding moths in spring, chafers and the most important aphids that may cause damage this year, together with the possibilities for their control. Finally, we may read about the three major apple diseases, powdery mildew, scab and fireblight, and how to prepare for their control.

Thoughts about western corn rootworm in spring of 2006
(László Vasas)
The author draws the attention to the continuously increasing populations of western corn rootworm. In connection with this, he points out that population density is basically determined by the weather conditions prevailing during the egg-laying period of the previous year. We may get to know the forecast for this year in the light of weather records and populations of western corn rootworm in 2005. Furthermore, the author gives an account of the different control strategies in maize grown in monoculture and crop rotation. He demonstrates with calculations that the major strength of the univoltine western corn rootworm is its fecundity. Readers find efficient methods for reducing population density of this pest at the end of the article

Western corn rootworm – What will happen if we will be without rainfall this season?
(József Takács, Zoltán Pirgi, Tamás Németh)
The authors are seeking the answer to the important question: what should we count on for this season regarding western corn rootworm? As they say, nobody can tell how hard the winter was, how high egg mortality is and especially, whether maize would lodge or not. The single thing that can be stated is that the hard winter could do almost nothing against the beetle. There was a dry period during the egg-laying of western corn rootworm in 2005, so it is likely that we may encounter with larval damages on the wet spots in the fields. Forecasting of the pest, much care and proper soil treatment would gain more importance in such areas.

The occurrence of major insect pests of maize in Southern Transdanubia in 2005
(Dr. Sándor Keszthelyi)
Analysing Hungarian climatic data for 2005, it can be concluded that there were rainy extremities during the season of maize. High volumes of rainfall and cool temperatures caused delayed development of both the crop and its insect pests. The author presents data on the flight activity of the three major maize pests observed in the fields in 2005, the damages caused by their larvae and adults and the situation that can be foreseen for 2006 from these records.

How to choose fungicides for winter wheat?
(Rozália Rátai Vida)
The specialist of the Plant Protection and Soil Conservation Service of County Jász-Nagykun-Szolnok calls drawers’ attention to that it is time to plan fungicide treatments for wheat fields in order to ensure crop safety. In the first part of the article the author deals with the most common pests of winter wheat, occurring at different growth stages and threatening the crop to different extent (powdery mildew, leaf rust, yellow rust, leaf spot and head blight), and the possible risks of their infection. She presents the data on the occurrence of the diseases and the factors influencing the success of their control, in a tabulated form, that should be known when making the fungicide programme. The fungicides registered for use in cereals are also tabulated. Finally, you may find certain useful recommendations for undertaking successful treatments.

PLEDGE + FRONTIER. Row in the same ship with the “champion doubles”! (x)
(Dr. László Magyar)
Sumit Agro Hungary Ltd. recommends the mixture PLEDGE + FRONTIER (flumioxazine + dimethenamid – P) for pre-emergence weed control in sunflowers.

Alternatives for weed control and costs in cereals (x)
(Tamás Fehér)
What and when to apply, and how much should we spend on weed control in wheat? Reading the article, the answer can be obtained from Hungarian Kwizda Ltd.

WORTHY OF ATTENTION

Which is the way future agriculture is going to? – or the lessons learned from an exhibition
(Dr. Norbert Somogyi)
The International Agricultural Show organised in Paris this year has a long history. More than six hundred thousand visitors were interested in the various kinds of animals bred and crops grown by farmers, the food French consumers ate and how they were prepared. The trends in French agriculture could also be seen. This year it was the first time when organisers provided a separate stand space for all the technical novelties that facilitate farmers’ job or indicate a completely new objective in production. Among the latter category, the renewable energy resources and industrial raw materials of biological origin play the leading role. The novelties displayed here could be seen also in the thematic sections providing more detailed information and explanation.

MECHANISATION, MACHINES

Adjusting sprayers to suit to orchards
(Dr. György Dimitrievics)
In fruit orchards, the success of treatments highly depends on choosing operation parameters of sprayers. Machines need be properly adjusted so that spray liquid could reach the targeted plant surface with the least loss possible and deposit there evenly. The orchards of different ages and management systems have different requirements for application technique, therefore it is important to choose operation parameters suited to orchard conditions. The expert of the Hungarian Institute of Agricultural Engineering takes into account the factors determining success of chemical treatments (working speed, specific spray volume, plant-recognising system). The paper also assists growers to identify proper operation parameters.
