Abstract

The results of a three-year (2020–2022) study of the eﬃcacy of the modern fungicide Ace, CSC of Russian production (pyraclostrobin - 80 g/l + prothioconazole - 40 g/l + tebuconazole - 160 g/l) against the pathogen of barley net blotch are presented. Barley is an important food, feed and fodder grain crop, ranking fourth in the world in terms of area planted and gross yields after wheat, rice and corn. Net blotch is the dominant disease in the pathocomplex of barley leaf diseases worldwide. One of the most eﬀective ways of plant protection in the world practice is the use of highly eﬀective fungicides. The experiment was conducted under ﬁeld stationary conditions. In the control (no treatment with the drug), the development of net blotch was 64.4; 86.7 and 49.2% in 2020, 2021 and 2022, respectively. The biological eﬃcacy of Ace fungicide, CSC against Pyrenophora teres Drechsler at the application rate of 1.0 l/ha was 98.4% in 2020, 89.4% in 2021 and 93.9% in 2022 on high background of disease development, which is comparable to known imported benchmarks. Protection of winter barley crops of the Romance variety with Ace fungicide, SCS provided grain yield increases of 10.6; 18.5 and 17.9% in 2020, 2021 and 2022, respectively. This fungicide is recommended for protection of winter barley against the pathogen of net blotch.
