SURFACTANT COMPOSITION THAT CAN BE USED IN GLYPHOSATE-CONTAINING HERBICIDE FORMULATIONS, GLYPHOSATE-CONTAINING HERBICIDE FORMULATION, AND USE OF THE GLYPHOSATE-CONTAINING HERBICIDE FORMULATION

摘要

The present invention relates to a surfactant composition for use in glyphosate-containing herbicide formulations, comprising from 5 to 50% by weight of one or more amphoteric surfactants, diluted in solvents derived from the process of synthesis thereof, wherein the surfactants have general formula (I)        R¹-(XR²)_m-N⁺(R³)(R⁴)-CH₂-CH(R⁵)-COO^-     (I)wherein R¹ is hydrogen or C_1-18 hydrocarbyl; each X is independently an ether, thioether, sulfoxide, ester, thioester or amide bond; each R² is independently a C_3-6 chain; m is a number from 0 to 8 such that the number of carbon atoms in R¹ - (XR²)_m is from 8 to 24; R³ and R⁴ are independently hydrogen or C_1-4 chains; R⁵ is hydrogen or methyl. The surfactant composition is used to increase the agronomic efficacy of herbicide formulations containing a high concentration of glyphosate salts. The present invention further describes herbicide formulations comprising such surfactant composition as well as the use thereof.
