U radu je prikazano praćenje razvoja bolesti pšenice u jednoj vegetacijskoj sezoni. Bolesti su se pratile na 4 lokacije; Osijek, Ivanovac, Josipovac i Samatovci, ukupne površine 110,5 hektara. Tijekom pregleda na polju i analize u laboratoriju na pšenici je zabiljeţena pojava bolesti uzrokovana patogenim gljivama: Mycosphaerella graminicola, Pyrenophora tritici-repentis i tri vrste iz roda Fusarium: F. graminearum, F. sambucinum i F. avenaceum. Zdravstvenom analizom zrna na svim lokalitetima je utvrĊena pojava Fusarium spp., no nije znaĉajnije utjecala na klijavost zrna. Na lokalitetu Osijek (Petros) je utvrĊena najveća zaraza (20 %). Alternaria sp. je pronaĊena na većini zrna, a na svakoj lokaciji je pronaĊen i Penicillium sp., In this paper monitoring of wheat's diseases development throughout the growing season is shown. Diseases were monitored at 4 locations; Osijek, Ivanovac, Josipovac and Samatovci, the total area of 110.5 hectares. During the examination in the field and the analysis in the laboratory, diseases caused by pathogenic fungi: Mycosphaerella graminicola, Pyrenophora tritici-repentis were recorded on the wheat and three species of the genus Fusarium: F. graminearum, F. sambucinum and F. avenaceum. By health analysis of wheat seeds at all locations the existence of phenomenon Fusarium spp. was determined, but it did not significantly affect the germination of grain. The largest infestation (20 %) was found on location Osijek (Petros). Alternaria sp. was found on most of the grains, but also Penicillium sp was found at each location.
