СРАВНИТЕЛЬНАЯ ОЦЕНКА БАКТЕРИАЛЬНЫХ ПРЕПАРАТОВ ПРИ ВОЗДЕЛЫВАНИИ ЯРОВОГО ОВСА В УСЛОВИЯХ АСТРАХАНСКОЙ ОБЛАСТИ

Abstract

Field research, sowing of spring oats with the use of bacterial preparations are carried out on the basis of the Institute of the Federal State Budgetary Research Institution "PAFSC RAS", which is located in the Northern part of the Astrakhan region. This article presents the results of studies on the effect of biological preparations (Rhizoagrin, Strain 17-1 and Strain 5S-2) on the yield of spring oats of the Borets and Lev variety in the Astrakhan region for 2019-2021. The analysis of the elements of the structure of the crop, varieties of spring oats is given. The yield of spring oats under control and the use of bacterial preparations is presented. An assessment of the effect of bacterial preparations based on microorganisms in spring oat crops in the conditions of the Astrakhan region was carried out. Observations of diseases of spring oats were carried out, the most disease-resistant variety of spring oats was Lion, whose seeds were treated with the bacterial preparation Rhizoagrin before sowing. Studies and observations of diseases of spring oats have shown that root rot pathogens mainly affect underdeveloped plants. The best results in suppressing powdery mildew were shown by the option with the treatment of Raxil Ultra seeds in combination with treatment with Phytosporin and Falcon. The best option for combating diseases of spring oats is the one where the bacterial preparation Rhizoagrin on the Lev variety was used as a seed mordant. The most disease-resistant variety of spring oats is Lion, whose seeds were treated before sowing with the bacterial preparation Rizoagrin, which has a wide spectrum of action on phytopathogenic microorganisms, suppressing the development and spread of pathogens of powdery mildew, septoria and fusarium.
