Responses of two populations of Xanthium strumarium L. (XS1 and XS2) and three populations of Helianthus annuus L. (HA1, HA2, HA3) to nicosulfuron were studied in controlled environment. Nicosulfuron applied at five different rates (0, 40, 60, 80 and 120 g/ha) when plants developed two pairs of leaves and control plants were not treated. Plant responses to growing rates of nicosulfuron were determined based on the next parameters: leaf area, fresh and dry weight, 7 days after herbicide application. Responses of populations of X. strumarium and H. annuus to nicosulfuron were different depend on population, herbicide rate and studied parameters. Resistance was not confirmed for any population. Namely, only reduced susceptibility of populations XS2 and HA2 to this herbicide were determined in comparison with referent susceptible populations.
