Definitions

  • the present subject matter relates to a herbicidal mixture for controlling undesired vegetation.
  • Mixtures of selected herbicides have several advantages over the use of a single herbicide including (a) an increase in the spectrum of weeds controlled or an extension of weed control over a longer period of time, (b) an improvement in crop safety by using minimum doses of selected herbicides applied in combination rather than a single high dose of one herbicide, and (c) a delay in the appearance of resistant weed species to selected herbicides ( Int . J. Agri. Biol., Vol. 6, No. 1, 2004, pages 209-212).
  • Aminopyralid Amino-3, 6-dichloropyridine-2-carboxylic acid was first reported by L. A. Brinkworth el al. ( Proc . BCPC Int. Congr., Glasgow, 2005, 1, 43). Its manufacture and its herbicidal action was described in WO 2001/051468.
  • Aminopyralid is a synthetic auxin which causes epinasty, followed by necrosis. It is a systemic, foliar and soil applied herbicide, which is rapidly absorbed by the leaves and roots.
  • Quinmerac 7-chloro-3-methyl-8-quinolinecarboxylic acid was first reported by B. Wuerzer et al. ( Proc . Br. Crop Prot. Conf. - Weeds, 1985, 1, 63) and W. Nuyken et al. (ibid., p. 71). Quinmerac induces the formation of 1-aminocyclopropane-l -carboxylic acid, leading to ethylene formation which induces the formation of abscisic acid (K. Grossmann & F. Scheltrup, Proc. Br. Crop Prot. Conf. - Weeds , 1995, 1, 393). It is taken up primarily via the roots, and in part also by the leaves. Quinmerac is used for post-emergence control of broad-leaved weeds in cereals, oilseed rape and sugar beet. The use of quinmerac as an herbicide is described in European patent EP 104389.
  • Aminopyralid is a highly effective post-emergence herbicide, in many cases it does not provide a sufficient control of the relevant harmful plants and its activity at low application rates is not always satisfactory. Further, it appears that aminopyralid is not sufficiently compatible with certain types of crop plants. As such, at the preferred application rates the useful crops are also damaged together with the undesired weeds.
  • the present subject matter relates to a herbicidal mixture comprising aminopyralid and quinmerac, or an ester or salt of any of the foregoing, or a combination thereof.
  • the present subject matter also relates to a composition
  • a composition comprising a mixture of aminopyralid and quinmerac, or an ester or salt of any of the foregoing, or a combination thereof.
  • the present subject matter also relates to a synergistic herbicidal mixture comprising aminopyralid and quinmerac, or an ester or salt of any of the foregoing, or a combination thereof.
  • the present subject matter also relates to a method of controlling undesired vegetation comprising applying to a locus of the undesired vegetation a herbicidally effective amount of a mixture comprising aminopyralid and quinmerac, or an ester or salt of any of the foregoing, or a combination thereof.
  • the mixture may be a synergistic mixture.
  • agriculturally acceptable carrier means carriers which are known and accepted in the art for the formation of formulations for agricultural or horticultural use.
  • plant or “crop” includes reference to whole plants, plant organs (e.g. leaves, stems, twigs, roots, trunks, limbs, shoots, fruits etc.), plant cells, or plant seeds. This term also encompasses plant crops such as fruits.
  • plant may include the propagation material thereof, which may include all the generative parts of the plant such as seeds and vegetative plant material such as cuttings and tubers, which can be used for the multiplication of the plant.
  • plant includes reference to agricultural crops including, but not limited to, field crops, vegetable crops, fruits, semi-perennial crops and perennial crops.
  • locus includes not only areas where weeds may already be growing, but also areas where weeds have yet to emerge, and also to areas under cultivation. Locus also includes the area surrounding the plant and the growing media of the plant, such as soil.
  • weed refers to plants which grow in locations in which they are not desired. In other words, a weed is a plant which is undesirable due to competition with the useful crop, for water, nutrients, sunlight, soil.
  • ha refers to hectare
  • post-emergence refers to the application of the herbicide composition to the weeds that have emerged from the soil.
  • pre-emergence refers to the application of the herbicide composition to a habitat, a weed, or soil, prior to the emergence of the weeds from the soil.
  • control of undesirable vegetation refers to the interference with the normal growth and development of undesired vegetation. Examples of control activity include, but are not limited to, inhibition of root growth, inhibition of shoot growth, inhibition of shoot emergence, inhibition of seed production, or reduction of weed biomass.
  • the term “effective” when used to describe mixture, composition and a method for controlling of undesired pest means that the mixture, composition and a method provide a good level of control of the undesired pest.
  • the term "effective amount” refers to an amount of the compound and/or mixture that, when applied, is sufficient to kill a weed.
  • the “effective amount” will vary depending on the concentration, the type of plants(s), the severity of the weed infestation, the result desired, and the life stage of the weeds during treatment etc. Therefore, it is not always possible to specify a specific “effective amount.” However, a suitable “effective amount” may be determined by one of ordinary skill in the art.
  • the term “broad spectrum” is used to describe efficiency against a wide range of weeds, the locus thereof or propagation material thereof.
  • tank mix means that aminopyralid and quinmerac are mixed in a tank prior to the application.
  • cultiva plants includes plants which have been modified by breeding, mutagenesis or genetic engineering. Genetically modified plants are plants, which their genetic material has been modified by the use of recombinant DNA techniques. Typically, one or more genes have been integrated into the genetic material of such a plant in order to improve certain properties of the plant.
  • plant health comprises various sorts of improvements of plants that are not connected to the control of pests.
  • advantageous properties are improved crop characteristics including: emergence, crop yields, protein content, oil content, starch content, more developed root system (improved root growth), improved stress tolerance (e.g.
  • improved visual appearance and composition of the plant i.e., improved color, density, uniformity, compactness, dimensions), reduced ethylene (reduced production and/or inhibition of reception), increase in plant height, bigger leaf blade, less dead basal leaves, stronger tillers, greener leaf color, pigment content, photosynthetic activity, improved visual appearance and composition of harvested material (i.e ., seeds, fruits, leaves, vegetables, shoot/stem/cane), less input needed (such as fertilizers or water), improved carbohydrate content (i.e., increased quantities of sugar and/or starch, improved sugar acid ratio, reduction of reducing sugars, increased rate of development of sugar), less seeds needed, more productive tillers, earlier flowering, early grain maturity, less plant verse (lodging), increased shoot growth, enhanced plant vigor, improved nutritional value, reduction in anti -nutritional compounds, increased nutrient uptake, stronger and healthier roots, improved organoleptic properties (i.e., improved taste), improved consumer health benefits (i.e

  • adjuvants may be understood to include, spreading agents, penetrants, compatibility agents, and drift retardants.
  • agriculturally acceptable inert additives is defined as any substance that itself is not an active ingredient but is added to the composition such as thickening agents, sticking agents, surfactants, synergists, anti-oxidation agent, anti-foaming agents and thickeners.
  • the combination provides a higher herbicidal activity than that envisaged on the basis of the sum of activities of each of the herbicides found therein. Such a combination allows the reduced dosages of the individual herbicides which can damage agriculturally important plants.

  • the present subject matter relates to a synergistic herbicidal mixture of aminopyralid and quinmerac, or an ester or salt of any of the foregoing, and/or a combination thereof.

  • the relative weight ratio of aminopyralid to quinmerac is preferably in the range from 1 :500 to 500: 1, in particular in the range from 1 :250 to 250:1 and more preferably from 100:1 to 1:100. Accordingly, in the methods and uses of the invention, aminopyralid and quinmerac are applied within these weight ratios.
