ALKOXYLATED POLYSORBATE ESTER ADDITIVE Russian patent published in 2019 - IPC A01N25/30 C08G65/08 C08K5/103 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, in particular to agrochemical compositions for treatment of plants. Agrochemical composition contains an agricultural active substance and an additive having a common structure Sorb. (AO₁H)_n1(AO₂H)_n2(AO₃H)_n3(AO₄R¹)_n4, in which Sorb is a sorbitan or sorbitan derivative residue; AO₁, AO₂, AO₃ and AO₄ each independently represents an oxyalkylene group formed from oxyethylene blocks, oxypropylene blocks or mixtures thereof, wherein at least one of groups AO₁, AO₂, AO₃ and AO₄ contains a mixture of oxypropylene and oxyethylene blocks, and the oxyalkylene chain is a block-copolymer; total number of moles of oxyethylene blocks present in each additive molecule ranges from 4 to 18; total amount of moles of oxypropylene blocks in each additive molecule ranges from 2 to 17; total number of oxyethylene blocks and oxypropylene blocks ranges from 8 to 32; n1, n2, and n3 independently represent an integer having value of 0 or 1; n4 is value of 1; and R¹ is a group of alkanoyl -C(O)R², in which R² is hydrocarbyl C₄-C₂₈. Agrochemical composition is used in methods for treatment of plants.

EFFECT: addition of additive of specified structure to agrochemical compound imparts surface activity to agrochemical composition, improves its physical and chemical properties and provides increased efficiency of agricultural active substance.
