Fusarium langsethiae, a toxigenic fungus known to contaminate small-grain cereals with type A trichothecene mycotoxins, HT-2 and T-2 was described as a new species in 2004. HT-2 and T-2 are some of the most potent Fusarium toxins in eukaryotes, capable of inhibiting protein synthesis. The epidemiology of F. langsethiae is not well understood and with the intent of the European Commission to set maximum levels of contamination of cereals with these toxins, importance is currently placed in trying to understand the fungal infection process and its favorable growth conditions. A field study was carried out to investigate the effect of artificially inoculated oats straw, ploughing and minimum tillage with and without incorporated crop debris (straw) on infection and mycotoxin production by F. langsethiae on oats cultivar Gerald. The results indicated that cultural field practices had effects on the infection of oats by F. langsethiae. Fusarium langsethiae DNA was quantified in significantly larger amounts (p<0.05) in minimum tilled with incorporated straw plot samples than in other plot samples. It was also shown that inoculated straw had no significant effect (p>0.05) on oat infection by F. langsethiae as quantified by DNA concentration. HT-2+T-2 quantification and analysis, gave no good evidence that either inoculation or cultural practice had any significant influence on the concentration of mycotoxins in the samples (p>0.05), but samples from minimum tillage with incorporated straw plots resulted in 2.5 times more HT-2+T-2 toxins than samples from ploughed with removed straw. These findings indicate the importance of tillage and crop debris management in the mitigation in an effort to prevent F. langsethiae infection, colonization and possible contamination of oats with HT-2 and T-2 toxins.

The development of the maize hybrid Martonvásári 5 gave an enormous boost to the research institute a few years after its establishment. For decades afterwards the Martonvásár maize breeding team played a successful and dominant role both in Hungarian scientific life and in the field of practical results. In addition to breeding, great emphasis was placed on agronomic research, aimed at improving the success of maize production. Martonvásár was the first to introduce hybrid maize in Hungary and to elaborate field technologies and processing techniques for hybrid maize seed production.These successes came at a time when the need was felt to modernise the whole of Hungarian agriculture, so within a few years, the whole of the maize-growing area of the country was sown to Martonvásár hybrids.Fifty years after the registration of the hybrid Martonvásári 5, even though faced by strong international competition, Martonvásár still ranks first among Hungarian breeders, and occupies the 3
place compared with the multinational companies.
