Net blotch caused by Drechslera teres is an important disease in most barley-growing areas. To prevent the introduction of this pathogen into the field, seed treatment is recommended. The objectives of this research were to evaluate different fungicides for eradicating D. teres from the seed and the role of both infected and treated seeds in the epidemiology of the disease under field conditions. The three fungicides tested in vitro (iminoctadine, guazatine, and thiram + iprodione) were able to eliminate D. teres at the highest dose used in this study. Under field conditions, eradication of the pathogen was not achieved, but net blotch was significantly reduced.
