Submitted by Гость (not verified) on Wed, 02/04/2026 - 22:38

The aim of this research was to evaluate the efficacy of biological fungicides against winter barley root rot pathogens for their subsequent practical application in ecological protection technologies within the Krasnodar Territory. The experiments were conducted at the Federal Scientific Center for Biological Plant Protection (FRCBPP) under field infection nursery conditions during 2023–2025. The object of study comprised winter barley root rot pathogens of Fusarium and Helminthosporium etiology.

The study was conducted to investigate the sensitivity of net blotch of barley (pathogen – Pyrenophora teres Drechsler) to two-component fungicides based on triazole and strobilurine classes. The work was carried out on intact barley plants and in pure culture of the fungus using four preparations (Amistar Extra, SC, Amistar Gold, SC, Baliy, MC, Delaro, SC) and five treatment options with different application rates from those recommended by the manufacturers (0 (control without fungicide), 50%, 100% (manufacturers’ recommended rate), 150%, 200%).

The aim of the study was to develop a new breeding material combining resistance to the main harmful diseases with high yield potential and good baking qualities of the grain. Productive, winterhardy winter wheat varieties of the FRC “Nemchinovka” breeding line, well adapted to the central region of the Russian Federation, and productive short-stemmed varieties of Hungarian selection with resistance to European populations of rust fungi, powdery mildew, fusarium and leaf spots were selected as parental components for crossing.
