Abstract

Goal. To determine the effectiveness of promising fungicide compositions for controlling the pathogens of fusariosis in seed treatment and their effect on the productivity of winter wheat.

Methods. Field, against the background of artificial infection Fusarium spp. The preparations were used in the treatment of winter wheat seeds of the Smuglyanka variety (BBCH 00) before sowing, and also during the flowering period — VVSN51. Statistical processing of research results was performed by analysis of variance using Excel.

Results. For prolonged protection of the zone of the root system of seedlings of plants, the effectiveness of treating compositions was studied, which include components with a low level of metabolism and apical transport, as well as fungicidal treating agents — derivatives of the class of triazoles, imidazoles, benzimidazoles, second-generation succinate dehydrogenase inhibitors and phenylpyrroles with insecticidal protectants. It has been established that for seed treatment, the use of fludioxonil-based preparations is effective. The level of control of Fusarium pathogens increased with the introduction of a composition of fludioxonil with sedaxan and insecticidal components. Tebuconazole and compositions of tebuconazole with prothioconazole and diphenoconazole are effective for controlling spike fusarium.

Conclusions. The most reliable protection of crops from Fusarium infections is the formation of agrophytocenosis with a low level of infectious background due to the reduction in the rotation of the areas of donor crops Fusarium spp. Minimization of soil cultivation contributes to the spread of pathogens of Fusarium. The key elements for obtaining healthy sowing are the introduction of cultivar-resistant varieties and hybrids resistant to Fusarium spp. And the use of highly effective fungicides and their compositions, including succinate dehydrogenase inhibitors, with insecticides during the growing season.
