摘要

A herbicidal preparation comprises both a compound of general formula (I): IMAGE [wherein: R1 is alkyl, alkenyl, alkynyl, benzyl, cycloalkyl or cycloalkenyl, all of which may be optionally substituted; R2 is haloalkoxy; R3 is halo; X is CN or halo; each Y is independently halo, CN, NO2, OH, alkyl, alkoxy, alkylthio, alkoxyalkyl, SO2alkyl, CONRaRb or heterocyclyl, or two Y groups together form a further ring; m is 0 - 4 Ra and Rb are independantly H or lower alkyl] and glyphosate (or a herbicidally acceptable salt or derivative thereof).
