The biological protection of soybean in the conditions of the eastern part of forest-steppe in Ukraine

The given article presents the assessment of the influence of biological preparations Biopolicyd, Rizoplan and Chetomic on the spread and development of soybean root rots as well as on the economic characters in comparison with the chemical protectant Vitavaks 200 FF VSK (200 + 200 g/l). The influence of preparations on disease agents control in field conditions and in vitro is studied. The high efficiency of preparations Vitavaks 200 FF VSK (200 + 200 g/l) and Chetomic in vitro on the development control of mycelium fungus is determined. But there was established the negative effect of the widely used preparation Vitavaks 200 FF VSK (200 + 200 g/l) on the crop productivity and the positive effect of the biological preparations applied for soybean seeds treatment.
