HERBICIDE MIXTURES BASED ON AUXIN Russian patent published in 2018 - IPC A01N33/08 A01P13/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture. To obtain a mixture of herbicides, a herbicide on the basis of auxin containing a first cation is combined with an adjuvant, which contains a salt containing a second cation, the salt being selected from the group consisting of: (a) ammonium salts of Formula I

,

where R¹, R², R³ and R⁴ each independently is butyl and X is agronomically acceptable anion; (b) salt containing nitrogen-containing heterocycle of Formula II

,

where A is a 5- or 6-membered heterocyclic ring; R⁵ is alkyl C₁-C₂₀; R⁶ is hydrogen or alkyl C₁-C₆, and X is an agronomically acceptable anion; (c) phosphonium salts of Formula III

,

where R⁷, R⁸, R⁹ and R¹⁰ independently represent a non-cyclic hydrocarbon residue of C₁-C₁₂ and X is agronomically acceptable anion; and mixtures thereof, and wherein the herbicide mixture has a total herbicide concentration of not more than about 40 % by weight of the acid equivalent (a.e.).

EFFECT: invention allows to reduce volatility of herbicides.
