Features of Growth and Development of Sugar Beet Hybrid Plants During the Period of Herbicide Stress

Abstract

Evgeny V. Zheryakov

The article presents the results of studies of the resistance of sugar beet plants of various hybrids to the negative impact of herbicides. At the initial stages of their growth, the most resistant to the negative impact of herbicides were sugar beet plants of the F1 Skala, F1 Priliv and F1 Burya hybrids. After the second treatment, growth inhibition with an increase in mass deficit was observed in the variants using herbicides. The F1 Skala hybrid was the most resistant to the negative impact of herbicides. In the F1 Priliv and F1 Gorizont hybrids, the effect of the chemical stress factor was assessed as the most toxic. The phytotoxicity of the herbicide combination for sugar beet was noticeably reduced (up to 12-13%), compared with earlier herbicide treatments. After three herbicide treatments, high resistance to the negative effects of herbicides was noted in the F1 Skala hybrid.
