Wheat diseases and protection measured on Family farm Miljević in year 2017

Abstract

Cilj rada je bio pratiti pojavu bolesti na pšenici na OPG Miljević (Privlaka) u 2016./2017. vegetacijskoj godini te odrediti mjere zaštite. Tijekom vegetacije uočena je vrlo slaba pojava lisnih bolesti i to pjegavosti lista (S. tritici) i pepelnice (B. graminis). U mliječnoj zriobi nije utvrđena pojava fuzarijske paleži klasova. Tretiranje fungicidima je obavljeno dva puta (jedna zaštita lista i jedna zaštita klasa). Nakon žetve utvrđeno je zdravstveno stanje zrna (4x100 zrna za svaku sortu) metodom izmrzavanja te je utvrđena dominantna prisutnost Alternaria sp. Također je utvrđena i sporadična pojava Fusarium vrsta te slaba do srednje jaka pojava saprofitnih vrsta iz rodova Penicillium i Aspergillus.The aim of this thesis was to monitor the occurence of wheat disease on Family farm Miljević (Privlaka) in 2016./2017. vegetation year and to determine the protection measures. During the vegetation it was noticed a slight appearance of leaf disease such as common leaf spots (S. tritici) and powdery mildew (B. graminis). In milk maturation the appearance of Fusarium head blight was not established. Treatment whit fungicides was performed twice (one time leaf protection and one time head protection). After the harvest, health status of the grains was determined (4 x 100 grains for each sort) by the deep freezing method and the dominant presence of Alternaria sp. was found. Also, there were found sporadic appearance of Fusarium species and weak to medium occurence of saprophytic species from the genera Penicilium and Aspergillus
