Glyphosate compositions and their use |
(57) The invention relates to a herbicidal composition comprising:
- (a) glyphosate acid or an agriculturally acceptable salt or derivative thereof, and
- (b) a surface active component having the formula or a quaternized form thereof or
the amine oxide derivative thereof, wherein R1 and R2 each independently represent
a straight or branched chain alkyl or alkenyl group having from 4 to 24 C-atoms, R3
in each (R3-O)-group may be the same or different and represents alkylene having from
2 to 4 carbon atoms, and x and y are average numbers such that x+y is in the range
from 2 to 160. It further relates to adjuvant compositions comprising such surface
active compounds and to a method for the control or kill of unwanted vegetation by
the use of such compositions. These compositions show improved herbicidal efficacy
and may contain high concentrations of glyphosate.
