The article presents the research on breeding and chemical methods of brown mustard sowings from Fusarium blight in the conditions of the central zone of the Krasnodar region. We evaluated mustard variety samples affected by the disease on a natural infectious background during the growing season. As a result, for 4 years we selected mustard breeding material resistant to Fusarium blight, which exceeds the productivity and oil content of the standard variety Yunona by 0.20-0.26 t/ha and 2.0-2.7 %, respectively. We tested systemic chemical fungicides from the triazoles and strobilurins groups in a chemical method study. We determined the fungicide with the active ingredients azoxystrobin 120 g/l + tebuconazole 200 g/l, SC at the application rate of 1.0 l/ha which effectively decreases the spreading and development of Fusarium blight on mustard when treating plants at the stalking stage. The biological effectiveness of the preparation was 82.4 %, the seed yield significantly exceeded the control (by 0.36 t/ha). Thus, it is recommended to use both breeding and chemical methods of sowings protection against the disease to effectively decrease the harmfulness of Fusarium blight on mustard.
