ACTIVITY OF THE MICROBIOCENOSE OF THE ROOT ZONE OF CORN PLANTS UNDER THE ACTION OF PLANT PROTECTION AGENTS

The vast majority of modern chemical poisons solve the problem of diseases and pests on agricultural plants. However, their use causes deterioration of the ecological condition of agrocenoses. The biological activity of the soil of the root zone of corn was studied during the pre-sowing treatment of seeds with a complex of microorganisms No.1 + No.2. It was found that the use of a complex of microorganisms No. 1 + No. 2 reduced the number of micromycetes by 1.8–2.5 times. The level of antifungal activity increased 4‒7 times compared to the control, and 1.5 times compared to the options where chemical preparations were used. Therefore, bioagents of complex No. 1 and No. 2, being introduced into the root zone of corn plants, initiate changes in the functioning of the microbiocenosis and protect plants during the growing season. We believe that the complex of microorganisms No. 1 and No. 2 is promising for further biotechnological developments.
