Intezivna pojava žute rđe pšenice (Puccinia Striiformis Westend ) na području grada Bihaća

Wheat rust (Puccinia striiformis) is the most important plant disease which we encounter for many years. Development of yellow rust on wheat depends on the weather conditions, primarily on increased rainfall and lower temperatures. The aim of this study was to demonstrate the connection between climate changes with the emergence of specific diseases such as rust of wheat, which intensively occurs in areas with colder climate. This paper deals with the occurrence of rust on wheat for three consecutive years: 2014, 2015 and 2016 on the varieties of wheat that are commonly used in the Una Sana Canton, a types Bosanka and Novosadska S 40. The highest level of disease was observed in 2014 on the mentioned varieties. During 2015 there has not been occurrence of rust on wheat, whereas in 2016 on the wheat variet Bosanka occurrence of rust was observed again, less pronounced than it was in 2014.Rđa pšenice (Puccinia striiformis) je značajno oboljenje sa kojim se susrećemo duži niz godina. Razvoj žute rđe na pšenici ovisi o vremenskim uvetima, prvenstveno o povećanoj količini padavina i nižim temperaturama. Cilj ovog rada bio je dokazivanje povezanosti klimatskih promena sa pojavom specifičnih bolesti kao što je rđa pšenice koja se intenzivnije javlja u područjima sa hladnijim klimatom. U ovom radu praćena je pojava rđe na pšenici tokom tri uzastopne godine: 2014., 2015. i 2016. na sortama pšenice koje se najčešće koriste na području Unsko sanskog kantona, Bosanka i NS 40S. Najveći intenzitet bolesti primećen je tokom 2014. godine na pomenutim sortama. Tokom 2015. godine nije došlo do pojave rđe na pšenici dok je 2016. godine na sorti pšenice Bosanka ponovo primećena pojava rđe manjeg intenziteta nego što je to bilo 2014. godine
