Wheat and barley diseases at PO Kalac in year 2022

Abstract

Cilj rada je bio utvrditi pojavu i razvoj bolesti na usjevima pšenice i ječma na P.O. Kalac u vegetacijskoj godini 2021./2022. te odrediti potrebite mjere zaštite. Polja na kojem je zasijan ozimi ječam i pšenica su na području Tompojevaca, a ukupno je zasijanih 70 ha. Temeljem praćenja i vizualnih pregleda utvrđena je prisutnost sljedećih uzročnika bolesti: Blumeria graminis (DC .) Speer, Septoria tritici Rob. Et Desm., Pyrenophora tritici-repentis (Died.) Drechsler, Fusarium graminearum Schwabe, Barley yellow dwarf (BYDV) i Pyrenophora teres Drechsler. Zaštita ječma je obavljena s dva fungicidna tretmana, dok je zaštita kod pšenice obavljena s tri fungicidna tretmana (dva tretmana za zaštitu lista i jedan tretman za zaštitu klasa).The aim of the work was to monitor the occurrence and development of diseases on wheat and barley crops at P.O. Kalac in the growing year 2021./2022, and determine the necessary protection measures. The fields where winter barley and wheat are sown are in the area of Tompojevci with a total of 70 ha. Based on monitoring and visual inspections, the following diseases were observed during vegetation: Blumeria graminis (DC.) Speer, Septoria tritici Rob. And Desm., Pyrenophora tritici-repentis (Died.) Drechsler, Fusarium graminearum Schwabe, Barley yellow dwarf (BYDV) and Pyrenophora teres Drechsler. Barley protection was performed with two fungicidal treatments, while wheat protection was performed with three fungicidal treatments (two treatments for leaf protection and one treatment for spikes protection
