Application of a Growth Regulator Based on 24-Epibrassinolide in Sugar Beet Cultivation Technology

Abstract

Abstract To suppress weeds in the crops of sugar beets, 2 to 5 treatments with herbicides are carried out, which worsens the quality of the resulting plant products and increases the risk of the formation of populations of weeds resistant to herbicides. To reduce the application rate of the herbicide in sugar beet crops, growth regulators based on the active ingredient–24–epibrassinolide were used, which increases the culture’s resistance to unfavorable environmental factors. It has been experimentally shown that the use of a growth regulator in a tank mixture with a 23% lower rate of herbicide applicaition in the growth phase of a BBCH 12–14 crop increased the herbicidal effect and promoted active growth of the crop. This technique had a positive effect on the quantity and quality of the sugar beet root crop. A statistically significant effect is shown from the use of 24-epibrassinolide in a tank mixture with a fungicide, as a result of which an increase in the adaptive potential of a cultivated plant against fungal diseases (the causative agent of micromycetes Cercospora beticola, Phoma betae) was observed.
