Growth and development features of sugar beet domestic hybrids during the herbicide stress period

The article presents the study results on the resistance of different sugar beet hybrids to the negative impact of herbicides. At the initial growth stages, sugar beet plants of the hybrids F1 Skala, F1 Priliv (Tide), and F1 Burya (Storm) were highly resistant to the negative impact of herbicides. After the second treatment of fields with sugar beet plants with herbicides, we observed growth inhibition signs with the increasing weight deficit. The hybrid F1 Skala was best resistant to the negative impact of herbicides. The hybrids F1 Priliv and F1 Horizont were least resistant to the toxic effect of chemical stress. The phytotoxicity of the herbicide combination for sugar beet markedly reduced (to 12–13 %) in contrast to the previous herbicide treatments. After three herbicide treatments, the F1 hybrid Skala showed best resistance to the negative impact of herbicides.
