Abstract Research on the effect of herbicides against dicotyledonous weeds Betanal Extra and against grass weeds Centurion on uterine beet growth and development is widely used on sugar beet.No significant difference according to the rules and types of herbicides as ChS component and pollinators and polyspermous for fractional composition of roots was found. The basic amount of ChS component of uterine plants was 150 g from 66 to 72%, polyspermous pollinators - from 46 to 72%, which can be planted by existing planting machines. In the meantime, as on the control such roots by the components were 66 and 42% respectively. However, negative influence of these herbicides on seed biometric indicators, which uterine plants were treated with, wasn’t set. Significant violations of ploidy of uterine beet plant components were determined. Uterine sugar beet treatment with maximum dose of herbicides is recommended for sugar beet sowings, the number of diploids is decreased by 51.3–54.2%, while the number of miksploids is increased in 3,9–4,1 times in comparison with the control. The least chromosomal device change is undergone by the uterine plants processing of Betanal Expert herbicide in norm 1 l/ha. Seed analysis showed that even with such significant violations of ploidy of uterine sugar beet plant components, there is no significant influence of herbicides on seed quality, especially for its purity. Using Extra Betanal herbicide as completely norm and as half of the norm, from the recommended rate and Centurion herbicide half norm from the recommended has not led to germination and purity of seed decreasing. Germination of seed was 66–72% (66% in control), purity - 96,1–97,6% in control 96.6% (LSD05 = 2.6%).
