  • antidotally effective is meant an antidote used in an amount which is effective as an antidote to decrease the extent of injury caused by the herbicide to the desired crop species.
  • the weight ratio of herbicide (a) to antidote (b) is from about 16: 1 to about 0.25: 1, preferably from about 8: 1 to about 0.5: 1, more preferably from 2: 1 to about 1: 1.
  • antidotes suitable for use in the present invention include the following (in which alkyl, alkenyl, alkynyl and alkoxy groups and moieties thereof are 'lower' as hereinbefore defined; cycloalkyl and phenyl groups are optionally substituted as hereinbefore defined; halogen is as hereinbefore defined; cycloalkenyl groups have from three to six carbon atoms in the ring and are optionally substituted by lower alkyl, lower alkenyl, lower alkynyl, lower haloalkyl and halogen; and bicycloalkyl means a saturated fused bicycloalkane one ring of which contains from 5 to 8 carbon atoms and the other ring contains from 3 to 6 carbon atoms and is optionally substituted by lower alkyl or halogen): (i) a compound of the formula (VITI):
  • R and R which may be the same or different, are selected from the group consisting of alkenyl; haloalkenyl; hydrogen; alkyl; haloalkyl; alkynyl; cyanoalkyl; hydroxyalkyl; hydroxyhaloalkyl; haloalkylcarboxyalkyl; alkylcarboxyalkyl; alkoxycarboxyalkyl; thioalkylcarboxyalkyl; alkoxycarboalkyl; alkylcarbamyloxyalkyl; amino; formyl; haloalkyl-N-alkylamido; haloalkylamido; haloalkylamidoalkyl; haloalkyl-N-alkylamidoalkyl; haloalkylamidoalkenyl; alkylimino; cycloalkyl; alkylcycloalkyl; alkoxyalkyl; alkylsulfonyloxyalky
  • Especially preferred antidotes for use in the present invention include: cloquintocet, cloquintocet-mexyl, fenchlorazole, fenchlorazole- ethyl, benoxacor and R29148.
  • Herbicide, furilazole, benoxacor, dichlormid, cloquintocet, fenchlorazole, naphthalic anhydride and R29148 were applied as technical materials prepared in acetone. Mixtures of the Herbicide and safeners were applied post-emergence. Two weeks after treatment the percent reduction in plant growth, compared to an untreated control (the Herbicide sprayed alone), was assessed.
  • the safeners provided an antidotal effect on maize and wheat by decreasing the extent of injury caused by the Herbicide.
  • EXPERIMENTAL EXAMPLE 4 Representative compounds of formula (I), Compounds 2 and 82 and cloquintocet-mexyl, were applied as technical materials prepared in acetone to a locus comprising a natural population of Galium aparine and wheat (Triticum aestivum).
  • the percent reduction in plant growth, compared to an untreated control was assessed 20 and 33 days after treatment (DAT).
  • a product comprising: (a) an aryl vinyl ether derivative as defined in general formula (I) or an agriculturally acceptable salt or metal complex thereof, and (b) an antidote as hereinbefore described; as a combined preparation for simultaneous, separate or sequential use, for example, in controlling the growth of weeds at a locus, e.g. crop locus.
