FIELD: agriculture.
SUBSTANCE: invention relates to agriculture, in particular to new chemical compounds that exhibit herbicidal effect. The compound has a general structural formula (I) , in which A is , and R1 is an unsubstituted phenylpropanoid or monoterpenoid fragment and R2 is a substituted or unsubstituted phenylpropanoid or monoterpenoid fragment or is selected from a group consisting of H, M, substituted or unsubstituted C3-C7 unbranched or branched alkyl, substituted or unsubstituted C2-C7 unbranched or branched alkenyl, substituted or unsubstituted C3-C7 unbranched or branched alkenyl, substituted or unsubstituted C3-C7 unbranched or branched cycloalkyl, substituted or unsubstituted heteroaryl, and substituted or unsubstituted C3-C7 unbranched or branched cyclo alkenyl; and M is a counter-ion selected from a group consisting of sodium, potassium, calcium, magnesium, iron, zinc, copper, and ammonium.
EFFECT: new compounds have contact herbicidal activity, which provides for immediate control of vegetation, allows more profitable reduction of processing costs, improved control of vegetation, reduction of both direct and residual toxic effects on humans and animals, as well as reduction of the likelihood of herbicide retention on collected food crops, shows intensified systemic herbicidal activity before and after the emergence of seedlings.
