INFLUENCE OF THE HERBICIDE PENDIMETHALIN ON THE POPULATION OF MICROORGANISMS AND THE BIOLOGICAL ACTIVITY OF SOILS

The impact of herbicide A-STOMP (Pendimethalin 330 g/l) on dynamics and viability of microorganisms of serozyom soils was studied. It was established that treatment of serozyom soils with herbicide A-STOPM before planting potato leads to insignificant suppression of a number of soil-borne microorganisms (mainly actynomycetes and filamentous fungi), which is observed on 7^th day after sprinkling. After 30 days, the viability of microorganisms of the ammonifier group and spore bacteria is restored. At the same time, the number of weeds in potato crops after herbicide treatment was 2.5–3 times lower compared to the control.
