Abstract

The invention relates to agriculture, in particular, to mixture postemergence means of protection of grain crops and maize planting against undesired weeds. The invention is directed for developing a novel highly effective preparation for suppressing weeds in grain crops planting based on a mixture of low-volatile esters of 2,4-dichlorophenoxyacetic acid (C7-C 9) and florasulam with a widened temperature range use. The achieved result provides an emulsion concentrate of a herbicidal composition for suppressing weeds in grain crop planting comprising a mixture of low-volatile esters of 2,4-dichlorophenoxyacetic acid (C7-C9), mainly heptyl, octyl and nonyl esters taken in a molar ratio to acid residue 0.043-0,051:1:0.,032-0.039, with florasulam and alkylencarbonate taken in molar ratio to octyl ester of 2,4-dichlorophenoxyacetic acid 0.0025-0.0111:0.537-0.577:1, a cosolvent and an emulsifier. It is advisable to use nonionic surfactants as a mixture of alkoxylated alcohols with calcium alkylbenzolsulfonate in the presence of 2-ethylhexanol. The emulsion concentrate of a herbicidal composition provides high biological and economical effectiveness in combating undesired weeds in grain planting.

Description

(57) Изобретение относится к сельскому хозяйству, в частности к смесевым послевсходовым средствам защиты посевов зерновых культур и кукурузы от нежелательной растительности. Изобретение направлено на разработку нового высокоэффективного препарата для подавления сорной растительности в посевах зерновых культур на основе смеси сложных малолетучих эфиров 2,4-дихлорфеноксиуксусной кислоты (С7-С9) и флорасулама с расширенным температурным диапазоном применения. Достигнутым техническим результатом является эмульсионный концентрат гербицидной композиции для подавления сорной растительности в посевах зерновых культур, который содержит в своем составе композицию смеси сложных малолетучих эфиров 2,4-дихлорфеноксиуксусной кислоты (С7-С9), преимущественно сложных гептилового, октилового и нонилового эфиров, взятых в мольном отношении по кислотному остатку 0,043-0,051:1:0,032-0,039, с флорасуламом и алкиленкарбонатом, взятыми в мольном отношении к октиловому эфиру 2,4-дихлорфеноксиуксусной кислоты 0,0025-0,0111:0,537-0,577:1, сорастворитель и эмульгатор. Целесообразно в качестве эмульгатора использовать неионогенные поверхностно-активные вещества в виде смеси алкоксилированных спиртов с алкилбензолсульфонатом кальция в присутствии 2-этилгексанола. Эмульсионный концентрат гербицидной композиции обладает высокой биологической и хозяйственной эффективностью в борьбе с нежелательной растительностью в посевах зерновых культур.(57) The invention relates to agriculture, in particular to mixed post-emergence means for protecting crops of grain crops and corn from undesirable vegetation. The invention is directed to the development of a new highly effective drug for suppressing weeds in crops of grain crops based on a mixture of low volatile esters of 2,4-dichlorophenoxyacetic acid (C7-C9) and florasulam with an extended temperature range of use. The technical result achieved is an emulsion concentrate of a herbicidal composition for suppressing weeds in cereal crops, which contains a composition of a mixture of low volatile esters of 2,4-dichlorophenoxyacetic acid (C7-C9), mainly heptyl, octyl and nonyl esters, taken in the molar ratio of acid residue 0,043-0,051: 1: 0,032-0,039, with florasulam and alkylene carbonate taken in molar ratio to 2,4-dichlorophenoxyacetic acid octyl ester 0.0025-0.0111: 0.537-0.5 77: 1, cosolvent and emulsifier. It is advisable to use nonionic surfactants as an emulsifier in the form of a mixture of alkoxylated alcohols with calcium alkylbenzenesulfonate in the presence of 2-ethylhexanol. The emulsion concentrate of the herbicidal composition has high biological and economic efficiency in combating undesirable vegetation in crops of grain crops.
