FIELD: agriculture. ^ SUBSTANCE: invention may be used in agricultural practices for control of undesirable vegetation in grain crop plantations. The herbicidal composition contains substituted sulphonylurea individually or in a mixture, taken in herbicidally effective quantity, C5-C10 ether of 2,4-dichlorophenoxyacetic acid of normal or isomeric structure - 65-80 wt % or C5-C10 ether of 2-methoxy-3,6-dichlorobenzole acid of normal or isomeric structure - 60-75 wt %, a nonion-active agent - 15-30 wt %, a tertiary amine - 1-10 wt %. The tertiary amine is represented by tertiary alkylamine or hydroxyethylated alkylamine containing totally no more than 20 carbons in a molecule; one of the radicals containing not less than 8 carbons. The herbicidal composition is represented by a production form containing separately packaged compositions of dry and liquid components which are mixed before the herbicidal composition application. The dry composition contains substituted sulphonylurea individually or in a mixture, the sulphonylurea, taken in herbicidally effective quantity, C5-C10 ether of 2,4-dichlorophenoxyacetic acid of normal or isomeric structure - 65-80 wt % or C5-C10 ether of 2-methoxy-3,6-dichlorobenzole acid of normal or isomeric structure 60-75 wt %, a non-ion-active agent - 15-30 wt %, a tertiary amine or hydroxyethylated alkylamine- 1-30 wt %. The liquid composition is represented by an emulsifiable concentrate. The dry and liquid composition weight ratio is from 1: 20 to 1: 100 respectively. ^ EFFECT: invention allows to increase stability during the herbicidal composition storage, to improve the process liquid stability, to increase the preparation herbicidal activity. ^ 6 cl, 3 tbl, 6 ex |
