Influence of deflufenican herbicide on the chemical composition of essential oil Elsholtzia ciliata (Thunb.) Hyl

The effect of foliar treatment of plants with a phytoindesaturase herbicide inhibitor on the content and composition of the essential oil (EM) of Elsholtzia ciliata (Thunb.) Hyl. It has been established that, depending on the concentration of the drug, the hormonal balance in the redox enzymatic complex changes, which is manifested in a change in the composition of the EM, in particular, in the content of the main components: ketone elsholtion and ketone dehydroelsoltion. Processing plants E. ciliata (Thunb.) Hyl. drug diflufenikan causes a change in the hormonal balance in the multienzyme complex of the biosynthesis of essential oils, mainly affecting the balance of redox enzymatic systems. The intensity and nature of the effect depends on the concentration of the active substance in the solution: when the concentration of diflufenicane is 0.05 g/l, the inhibitory effect of the drug on the processes of biosynthesis of essential oils is observed. Treatment with the drug in lower concentrations of 0.005 and 0.0005 g/l leads to a shift in the equilibrium of the redox enzyme system towards the activation of dehydrogenases and an increase in the amount of ketone in the essential oil. Pre-harvesting plants with E. ciliata (Thunb.) Hyl. diflufenikan allows you to purposefully influence the change in the content of the main components of essential oils in the direction of the formation of more unsaturated components, which increases the antioxidant properties of the oil and its antimicrobial and antiviral activity.
