Changing weed control in maize
As a consequence of Hungary’s accession to the EU, various active substances (e.g. the most frequently used atrazine) were withdrawn due to their adverse physiological effect. More up-to-date, environmentally friendly active substances are needed to replace them. The author studied herbicides and mixtures of herbicides recently placed on the market and meeting the above requirements in sweetcorn. He informs on the phytotoxicity of the active substances applied in different modes (presowing /ppi/, pre-emergence, early postemergence and postemergence) in different varieties, summarised in tables.
We asked the processing company …
We asked the following questions from the professional of the Békéscsaba Refrigerating Co., Mr József Sztanek: “How long have you been dealing with the quick-freezing of sweetcorn?, Which are the varieties that you prefer for contracted growing?, What were the characteristics of the season in 2004?, What kinds of problems did you encounter in plant protection? What are the impacts of the increased quality requirements on the refrigerating industry?
The efficacy of herbicides in maize, depending on the timing of application
(László Szabó, István Dávid)
As it is known, the success of weed control is jointly determined by the used herbicide and the mode of its application. The authors studied the efficacy of 10 mixtures of herbicides against certain hard-to-control weeds in maize. They established a large-plot trial with two application dates in two replicates in calcareous chernozem soil on the area Debrecen–Látókép (in the great Plain, eastern Hungary) in 2004. The dominant weeds, thorn-apple (Datura stramonium) and barnyardgrass (Echinochloa crus-galli), were responsible for 94-95 % of the total area infested with weeds. The efficacy of the herbicides was assessed at two dates, the tabulated results are shown.
Experience of controlling cotton bollworm in sweetcorn
(László Vasas, István Zöldi)
The authors believe that cotton bollworm is not a pest that cannot be controlled. Good timing, as well as the monitoring of the flight and larval emergence are of vital importance. The classical method (treatment at the flight peak and 10-14 days after it) is not feasible for this pest. When the number of adults increases, the product shall already be on the plant so that the emerging larvae may get in contact with it. The authors think that the appropriate application technique and the efficient treatment of the ear-zone are also a key factor.

Variety describing trials with sweetcorn at the National Institute for Agricultural Quality Control
The author briefly outlines Hungary’s position in sweetcorn growing, last year’s difficulties in trading, the reasons of loosing markets and the grown varieties. In 2004 the National Institute for Agricultural Quality Control established a variety trial with 19 normally sweet and 7 super-sweet varieties where the season-length, the characteristics of the plant and the ears, as well as the productivity were evaluated in relation with the weather conditions. The author informs on the above parameters and the results of tasting for each variety that may be very helpful for growers in deciding which variety to produce.

National survey for ear blight of winter wheat in 2004
(Dr. György Kis, Ágoston Tóth)
Fusarium fungi are the causal agents of the most severe diseases of cereals. The greatest injury is provoked by ear blight, leading to significant losses in crop quality and quantity. Last year, examining ear samples taken in 551 wheat fields, the plant protection services recorded a level of infection (9,24 %) much higher than in the previous year. Severity of seed infection was very variable; it was in the range of 1.50 and 25.46%. The authors believe that this heterogeneity is caused by the weather conditions and the drastic decrease in disease control. They recommend growers to provide a preventive control with appropriate technique for cereals if the conditions favouring to the disease exist. The efficient fungicides registered for use are also outlined.
Ear blight in county Békés between 2002 and 2004

Cereal intervention – how to go on?
(Dr. László Rieger, Zsuzsanna Jancsok, Norbert Kató)
As in an EU member state, it is possible to take part in cereal intervention also in Hungary. The authors outline the key points and objectives of intervention, the position of the domestic cereal industry in the light of 2004 year’s record yields. In their opinion the acceptance is rather slow. Its reasons are the high volume of the produce offered in the country, the lack of practice and stores designated for intervention and the substandard conditions of the majority of the existing storage facilities. The authors recommend revision of the implementation of intervention in Hungary. They believe that the problems can be mitigated by decreasing the intervention commodity stocks, increasing the livestock and building storehouses in the country assisted by investment supports.
