ACTIVITY OF RHISOSPHERIC MICROBIOTES OF WINTER PEAS BY COMBINED ACTION OF HERBICIDE AND BIOLOGICAL PREPARATIONS

Abstract

The article presents the results of studies the total number of bacteria, micromycetes and azotobacter in the rhizosphere of winter peas, depending on the use of different rates of herbicide MaxiMox (0,8; 0,9; 1,0 and 1,1 l / ha), separately and in tank mixes with plant growth regulator Agriflex Amino (1,0 kg/ha) on the background of bacterization seeds material with the microbial preparation Optimize Pulse (3,28 l/t) and without background. The obtained results showed the dependence of the functioning of the rhizosphere microbiota of winter peas on the application of different herbicide rates, but with the complex application of MaxiMox (0,8–1,0 l/ha) with the plant growth regulator Agriflex Amino (1,0 kg/ha) on the background of bacterization seeds material with the microbial preparation Optimize Pulse (3,28 l/t) was observed to reduce the negative impact of xenobiotics on the soil microbiota, which was manifested in an increase the total number of bacteria by an average of 3-21%, micromycetes - 42-73% and azotobacter - 2-9%.
