New twin tail amine compounds and their zwitterionic derivatives

An adjuvant composition for modifying the spray properties of an aqueous pesticide composition comprising:

• a compound of general formula (I) or (II)
• wherein Rn and Rm independently represent a C3-C27 aliphatic group,
• R1 to R4, which may be the same or different at each occurrence, represent hydrogen or a C1-C8 alkyl group,
• X1 and X2, which may be the same or different at each occurrence, represent a linear or branched divalent hydrocarbon radical with 1 to 24 carbon atoms which can be optionally substituted and/or interrupted by one or more heteroatoms or heteroatom containing groups, and
• R5 and R6, which may be the same or different at each occurrence, represent a group selected from —O−, -Alk-CH(OH)—CH2—SO3− and -Alkx-CO2− wherein Alk represents an alkylene group, in an amount that is effective, when the adjuvant composition is diluted in the aqueous pesticide composition and the aqueous pesticide composition is spray applied, to reduce spray drift of the spray applied aqueous pesticide composition compared to an analogous spray applied pesticide composition that lacks the compound of general formula (I) or (II).

A method for controlling spray drift of an aqueous pesticide composition, comprising:

• incorporating in the aqueous pesticide composition a compound of general formula (I) or (II)
• wherein Rn and Rm independently represent a C3-C27 aliphatic group,
• R1 to R4, which may be the same or different at each occurrence, represent hydrogen or a C1-C8 alkyl group,
• X1 and X2, which may be the same or different at each occurrence, represent a linear or branched divalent hydrocarbon radical with 1 to 24 carbon atoms which can be optionally substituted and/or interrupted by one or more heteroatoms or heteroatom containing groups, and
• R5 and R6, which may be the same or different at each occurrence, represent a group selected from —O−, -Alk-CH(OH)—CH2—SO3− and -Alkx-CO2− wherein Alk represents an alkylene group, in an amount that is effective, when the end use pesticide composition is spray applied, to reduce spray drift of the spray applied pesticide composition compared to an analogous spray applied pesticide composition that lacks the compound of general formula (I) or (II), and spray applying the aqueous pesticide composition to a target pest or to an environment of the target pest.
