Definitions

  • the present invention relates to a synergistic herbicidal composition.
  • the invention also relates to a method of controlling the growth of undesirable vegetation, particularly in crops, including using the aforementioned composition.
  • herbicidal active ingredients have been shown to be more effective when applied in combination rather than applied individually, this effect being referred to as “synergism. ” According to Herbicide Handbook of the Weed Science Society of America, Seventh Edition, 1994, page 318, “synergism” is an interaction of two or more factors such that the effect when combined is greater than the predicted effect based on the response to each factor applied separately.
  • the terms “synergism” , “synergy” , and “synergistic” are used to describe this effect when two herbicides are combined, namely that the effect of the combination in terms of its herbicidal effect is greater than would be predicted based on a simple addition of the herbicidal effect of each herbicide alone; when combined the herbicides provide a supra-additive herbicidal effect.
  • Hexazinone and S-metolachlor are compounds that are known to be herbicidally active and to be of use in the control of unwanted plant growth. It has now surprisingly been found that a combination of hexazinone and S-metolachlor displays a synergistic effect in the control of plant growth when applied in combination, for example in a composition comprising these compounds or when applied together to a locus to be treated.
  • the herbicidal effect of the two when combined is greater than the sum of the herbicidal effect of each alone and in fact it was found that the combination can exhibit a significant herbicidal effect when the two are combined at levels that individually produced no or minimal herbicidal effect.
  • herbicidal active ingredients forming the herbicidal composition and used in the method of this invention are independently known in the art for their effects on plant growth. They are all disclosed in The Pesticides Manual, Twelfth Edition, 2000, published by The British Crop Protection Council. They are also commercially available.
  • the synergistic effects of the combinations of hexazinone and S-metolachlor forming the basis of the present invention can provide one or more of a number of advantages over the use of each component (A) hexazinone and (B) S-metolachlor alone.
  • the rates of application of each component can be markedly reduced, when used in combination, while maintaining a high level of herbicidal efficacy.
  • the treatment using these combinations can exhibit a considerably broader weed spectrum than does either of the components when used alone.
  • the use of the combinations can have the potential to control weed species at a low application rate, in particular a rate of application at which the individual components alone are ineffective.
  • the use of a composition comprising the aforementioned active components can have a speed of action which is faster than that which would have been predicted from the speed of each component used individually.
  • the present invention provides a composition comprising a herbicidally effective amount of (A) hexazinone and (B) S-metolachlor wherein the composition exhibits a synergistic herbicidal effect.
  • the composition contains a herbicidally effective amount of a combination of (A) hexazinone and (B) S-metolachlor.
  • herbicide refers to a compound that controls the growth of plants.
  • Herbicidally effective amount refers to the quantity of such a compound or combination of such compounds that is capable of producing a controlling effect on the growth of plants.
  • the controlling effects include all deviation from the natural development of the target plants, for example killing, retardation of one or more aspects of the development and growth of the plant, leaf burn, albinism, dwarfing and the like.
  • the synergistic effect of the combination of (A) hexazinone and (B) S-metolachlor means that the herbicidal effect is greater than the sum of the individual herbicidal effects.
  • plants refers to all physical parts of a plant, including shoots, leaves, needles, stalks, stems, fruit bodies, fruits, seeds, roots, tubers and rhizomes.
  • Hexazinone (IUPAC name: 3-cyclohexyl-6-dimethylamino-1-methyl-1, 3, 5-triazine-2, 4- (1H, 3H) -dione) has the following chemical structure:
  • Hexazinone is a photosynthetic electron transport inhibitor at the photosystem II receptor site. It can be absorbed by roots and leaves with translocation acropetally. It can be used to control annual and biennial weeds, and except for Sorghum halepense, some perennial weeds.
  • S-Metolachlor (IUPAC name: A mixture of (aRS, 1S) -2-chloro-6'-ethyl-N- (2-methoxy-1-methylethyl) aceto-o-toluidide and (aRS, 1R) -2-chloro-6'-ethyl-N- (2-methoxy-1-methylethyl) aceto-o-toluidide) has the following chemical structures:
  • S-Metolachlor is a cell division inhibitor inhibiting synthesis of very long chain fatty acids. It is a selective herbicide which absorbed predominantly by the hypocotyls and shoots and inhibits germination. It can be used to control annual grasses including Echinochloa, Digitaria, Setaria, Brachiaria, Panicum and Cyperus, and some broad-leaved weeds including Amaranthus, Capsella and Portulaca.
