Alkoxylated asymmetric alkylamine surfactants as adjuvants |
摘要 |
The present invention generally relates to a herbicidal formulation that comprises at least one phenoxy acid herbicide or an agriculturally acceptable salt or derivative thereof, and a surfactant adjuvant, wherein said surfactant adjuvant comprises at least one alkoxylated asymmetric alkylamine surfactant having the formula (I) wherein R1 is a straight or branched chain, saturated or unsaturated hydrocarbyl group having from 8 to 24 carbon atoms; R2 is a C1-C4 alkyl group or a benzyl group; A is an alkylene group containing from 2-4 carbon atoms; x is 1-30; and y is 0-10; or a quaternised derivative of (I) having the formula (II) wherein R1 is a straight or branched chain, saturated or unsaturated hydrocarbyl group having from 8 to 24 carbon atoms; R2 is a C1-C4 alkyl group or a benzyl group; A is an alkylene group containing from 2-4 carbon atoms; x is 1-30; y is 0-10; R3 is a C1-C4 alkyl group; and Y− is an anion. The invention also relates to a method for controlling unwanted vegetation which comprises applying an effective amount of the aforementioned herbicidal formulation to said unwanted vegetation.; |
