Popis: Under Hungarian conditions, head blight (caused by Fusarium spp.) means a risk of infection for wheat between flowering and harvest. The infection level and the damages of economic importance may be significant for both quantitative and qualitative aspects. Its qualitative damages must be noted because Fusarium species does not only attack plant germs, but they may also produce toxins harmful to the health of man and animals. Following the epidemics of head blight in 1970, the National Plant Protection Organization provided for a regular survey of the nation-wide spread of wheat seed infection. Out of the 27 years studied, epidemic spread of the disease occurred in 9 years. Spread of head blight on a large area was supported by the rainy weather during heading and flowering of the wheat, but it was also influenced by the plant protection techniques used. It is necessary to go on with the survey of Fusarium internal seed infection started in 1970, because seed-dressing and control management can be recommended for the farmers based on the adequate infection events. However, in addition to the establishment of Fusarium infection level determining the sowing value of seeds, it is also necessary to define the toxins produced by the pathogens together with their volume.
