20.500.12556/RUL-154748 Performance of symmetric double flat fan nozzles against fusarium head blight in durum wheat Four types of nozzles were tested on large-scale trials with a 40 m$^2$ plot unit size. The Avi Twin 110-01 (80 L ha$^{−1}$), 110-02 (160 L ha$^{−1}$), 110-03 (240 L ha$^{−1}$), and 110-04 (320 L ha$^{−1}$) symmetric double fan injector nozzles were tested during the 2020/2021 and 2021/2022 growing seasons. This study aimed to evaluate the performance of spray nozzles with regard to deoxynivalenol (DON) accumulation in durum wheat grains. Artificial inoculation with Fusarium spp. was performed after durum heads were protected with fungicide. The percentage of heads covered with fungicide droplets, grain yield, yield-related traits, technological quality parameters, and concentrations of DON were determined. Compared to the control (without fungicide treatment), the Avi Twin 04 nozzle caused a reduction of 45.0% in the DON concentration on average across both growing seasons. This positively corresponded to the percentage of heads covered with fungicide droplets, which was highest when this nozzle was utilized. In both trial years, the DON reduction caused by the 110-04 twin nozzle was higher than that caused by the 110-01 nozzle. Treatment with the 110-04 nozzle more effectively improved the grain yield, 1000-kernel weight, and test weight compared to treatment with the 110-01 nozzle and the untreated control. The differences in technological quality were less pronounced when different spray nozzles were used.. deoxynivalenol durum wheat technological application grain yield spray nozzle pšenica trdinka glivične bolezni varstvo rastlin pršilne šobe škropilniki nanašanje fitofarmacevtskih sredstev pridelek true false true Angleški jezik Slovenski jezik Članek v reviji 2024-02-28 11:53:38 2024-02-28 11:53:44 2024-02-29 03:41:02 0000-00-00 00:00:00 2024 0 0 15 str. iss. 3, art. 343 Vol. 14 2024 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 632 2077-0472 10.3390/agriculture14030343 187058947 agriculture-14-00343-v2.pdf agriculture-14-00343-v2.pdf 1 BCD7ACF50F8DB91BD8E0B508519E1C81 bb8a10625fb89314107a00270155857747da079543bd03cab08a76b2b49cc0e3 e8c01732-d627-11ee-86bb-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=181308 https://www.mdpi.com/2077-0472/14/3/343 1 a3bcfd6d-d627-11ee-86bb-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=181307 Biotehniška fakulteta 0 0 0
