THE EFFECT OF HERBICIDES ON THE BIODIVERSITY OF SOIL MICROORGANISMS
The article presents the results of a study of the effects of herbicides A-STOMP, GIANT 330 EC and Chemzalak-18% on the biodiversity of soil microorganisms used to control weeds in typical gray soils of cotton fields at the Okkurgan Research and Experimental Station of the Tashkent Regional Research Institute of Cotton Growing, Seed Production and Agrotechnology. It has been established that the use of herbicides A-STOMP and GIANT 330 EC causes a decrease in the total number of microorganisms, while the use of chemical chemicals-18% contributes to its increase. The study of morphological and cultural characteristics of isolated microorganisms showed significant differences in their taxonomic composition. At the same time, both in the control and in the experimental variants, representatives of the genus Bacillus were dominant.
