| Abstract | The results for the research of the effects of various norms of herbicide Lancelot 450 WG (13, 23, 33 g / ha) applied separately and combined with plant growth regulators Biolan and Radostym on the grouping of microbiota rhizosphere of winter wheat grown after different predecessors are given. It was established that the number of bacteria and micromicetes of winter wheat rhizosphere grown after different predecessor depends on the presowing treatment of seeds with PGR Radostym and postemergence apply of herbicide Lancelot 450 WG and PGR Biolan. The greatest number of bacterial and fungal microbiota is observed against the presowing treatment of winter wheat seeds with PGR Radostym and spraying with herbicide Lancelot 450 WG in the norms of 13 g / ha and PGR Biolan (20 ml / ha), which exceeds the control I over 58 and 91% after the maize for silage predecessor and 76 and 98% – after the perennial grasses predecessor. Larger quantities of microbiota of winter wheat rhizosphere are developed after the perennial grasses predecessor that is accorded with a higher intensity of plant physiological processes. | ||
