| Abstract | The research results of the effect of different rates of herbicide Lantselot 450 WG (13; 23; 33 g / ha) applied separately and in cooperation with plant growth regulators Biolan and Radostim on the development of specific ecologicaltrophic groups of microorganisms of winter wheat rhizosphere grown after different biologically active preparations and predecessors are given. It was determined that nitrifying agents of I and II phases are sensitive to herbicidal agent independently of predecessor, at the same time on the background of presowing treatment of seeds with PGR Radostym and spraying of crops with herbicide Lancelot 450 WG in the norms of 13 g / ha in cooperation with PGR Biolan (20 ml / ha) inhibiting effect on the development of these groups of microorganisms decreases. Ammonium and cellulose destructive bacteria of winter wheat rhizosphere turned out to be resistant to the effect of biologically active preparations, with the use of herbicide especially in cooperation with plant growth regulator there was a significant increase in their numbers. | ||
