Abstract
The subject of the present study was to investigate the effect of the herbicide Chicara-Duo, applied at a dose of 300 g / da in vineyards, on soil microorganisms. The herbicide has proven to reduce the amount of soil microorganisms. The persistence of the herbicide lasts until the 60th day after treatment, which shows that the biodegradation of this herbicide, is slower and can take a longer period of time, depending on the soil type and reaction.
