Table 5: Efficiency of _Puccinia coronata_ control [%] in years 2012–2016 in Winna Góra. use of tebuconazole (92.4%), picoxystrobin (90.8%), and epoxiconazole (88%). Azoxystrobin had the weakest effect, with effectiveness of 75.3%. In 2012, the oat grain yield from the control plots of the tested varieties ranged from 6.10 (Maczo) to 8.13 t \(\times\) ha\({}^{-1}\) (Hango) (Table 6). The use of fungicides from the chemical groups groups for triazoles and strobilurins allowed yields of 6.09 (azoxystrobin, Maczo variety)--8.71 t \(\times\) ha\({}^{-1}\) (picoxystrobin, Breton) to be obtained. The grain yield of the varieties compared to the control (100%) varied, and in the case of the Arab variety, it was 103-112%, versus the following: Arden, 99-103%; Bingo, 104-105%; Breton, 102-108%; and Maczo, 99-110%.
