The field trials were conducted in the years 2007–2009. Examined herbicide mixtures contained Betanal Progress 274 OF, Lontrel 300 SL and adiuvant Trend 90 EC, this was supplemented with Goltix 70 WP, Flirt 460 SC or Venzar 80 WP. The components of mixtures in two reduced doses (by 50% and 67%) were applied. The conducted trials indicated that examined microrate systems did not significantly differentiate the level of sugar and melassogenic contents in sugar beet roots. The sum of all detected residues amounted to 0.0022–0.0149 mg/kg. The highest levels of residues in the case a application of Betanal Elite 274 EC in full rates were detected. The examinated mictorate herbicide systems lower residues level were characterized. Rate reduction in these systems caused in general a significant decrease of residues.
