The year 2020, from the climatic point of view, was an unusual year, due to the fact that spring and the beginning of summer were was much colder, with much lower temperatures than the multiannual averages, inspired us to make observations on some diseases frequently found in Timiş County. Thus, we made observations on the fungus Septoria tritici Rob et Desm., which under normal conditions in Romania is a secondary disease that occurs in colder years, and in dry years is almost completely absent. Normally the septoria blotch does not end up infecting the gonfalon leaf (F) in any year, but this year due to low temperatures this fungus also reached the gonfalon leaf. In 2020 we studied the attack of Septoria tritici Rob et Desm., In six localities in Timiş County, in the wheat beech ripening phase, phenophase also delayed due to low temperatures, wheat accumulating more difficult this year the sum of temperatures necessary for its development.The localities studied were Beba veche, Murani, Bethausen, Poieni, Ştiuca, Clopodia and Foieni. The frequency (F%), the intensity (I%) and the frequency of attack of the fungus on the gonfalon leaf (F) and on the third leaf below the gonfalon (F-1) were assessed, the results were analyzed. statistically and analyzed as such.
