Abstract The results of scientific studies on the effects of different norms of herbicide Pulsar 40 (0.5, 0.75, 1.0 l/ha) applied for shoots alone and in combination with plant growth regulator Biolan 15 ml/ha on the activity of microbial groupings of pea rhizosphere which seeds were treated before sowing with biologicals Biolan 20 ml/t and Polimiksobakteryn 50 ml/t are shown. It is determined that the use of herbicide with biologicals affects the activity of rhizosphere microbiota of peas more positively than its independent applying. It is found that pre plant treatment of pea seeds promotes more intensive development of rhizosphere microorganisms. So the largest number of soil microorganisms is observed on the background of pre treatment of seeds with a mixture of biologicals Biolan (20 ml/t) and MB Polimiksobakteryn (50 ml/t) followed by crop spraying with herbicide Pulsar 40 in the norm of 0.5 l/ha together with growth regulator Biolan 15 ml/ha. It shows reducing the negative impact of xenobiotic on pea crops by stimulating influence of biologicals on rhizosphere microbiota.
