Abstract
In the modern agricultural production, the use of herbicides and other biologically active
substances is an important part of the cultivation technologies of most cereals, including the grain
sorghum. It is known that most preparations, including the chemical ones, can directly or indirectly
influence the development of microorganisms in the rhizosphere of plants, but the nature of their
effect on the number of microbiota of grain sorghum rhizosphere has not been studied enough,
which reasoned the relevance of this research. The number of microorganisms in the grain sorghum
rhizosphere (hybrid Milo W) was studied during 2019–2020 under the treatment by the herbicide
Citadel 25 OD (0.6; 0.8 and 1.0 dm3·ha–1), plant growth regulator Endophit L1 (30 cm3·ha–1) and
biological preparation Bioarsenal (800 g·100 kg–1). The analysis of the obtained experimental
data showed that use of the studied preparations both separately and in different compositions had
a stimulating effect on the number of grain sorghum rhizosphere microbiota, which was observed
in its increase, especially in variants with the combined use of the herbicide Citadel 25 OD, plant
growth regulator Endophit L1 and the biopreparation Bioarsenal (compared to the control the
number of rhizosphere microbiota increased by 29.4–80.6% in average by groups).
