Abstract: A surfactant composition for use in glyphosate-containing herbicide formulations, includes 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 C1-18 hydrocarbyl; each X is independently an ether, thioether, sulfoxide, ester, thioester or amide bond; each R2 is independently a C3-6 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 C1-4 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. Herbicide formulations including the surfactant composition and uses thereof are also provided.

Abstract: 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 C1-18 hydrocarbyl; each X is independently an ether, thioether, sulfoxide, ester, thioester or amide bond; each R2 is independently a C3-6 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 C1-4 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.

Abstract: The present invention relates to a novel adjuvant composition for use in herbicide formulations containing high concentrations of glyphosate salts, as well as herbicide formulations containing a novel adjuvant composition. The adjuvant composition of the present invention comprises one or more urea alkoxylated derivatives and can also contain further surfactants. The novel adjuvant composition described in the present invention can be incorporated in herbicide formulations which contain glyphosate salts, such as MIPA, potassium, MEA, TEA or mixtures thereof. These herbicide formulations may also contain additional herbicides in their composition. These glyphosate containing herbicide formulations can be used in liquid sprays for controlling weeds. In addition to being compatible with various glyphosate salts at different concentrations, the adjuvant composition of the present invention has shown to be capable of improving stability and agronomic effectiveness of these formulations.
