[0014] In a more preferred embodiment of the invention, the herbicidal composition comprises a mixture of components (A) and (B) as disclosed in Table 1 below.

[0015] [Table 2-1] [Table 2-2]

[0016] In general, the mixing ratio (by weight) of the compound of formula (I) to the compound of component B is 0.01:1 to 100:1, more preferably 0.025:1 to 20:1, even more preferably 1:30 to 20:1. Accordingly, the preferred ratio ranges for the preferred compositions of the present invention are shown in Tables 2 to 4 below. *It should be understood that when component (B) exists in alternative forms (e.g. salts / esters), these are interchangeable.

[0017] [Table 3-1] [Table 3-2]

[0018] [Table 4-1] [Table 4-2]

[0019] [Table 5-1] [Table 5-2]

[0020] Those skilled in the art will understand that the most preferred ratio range of A:B for any of composition numbers M1.001-M1.062, M2.001-M2.062, and M3.001-M3.062 described in Tables 2, 3, and 4 above may be 1:30-16:1, and each ratio can be optimized depending on the mixture partners. Suitable ratios of 1:30, 1:20, 1:10, 1:5, 1:4, 1:3, 1:2, 1:1, 2:1, 3:1, 4:1, 5:1, 10:1, 20:1, 30:1 are also contemplated.

[0021] It should be further understood that the composition of the present invention may further comprise one or more additional herbicidal active ingredients, thus providing a ternary, quaternary, or even quinary or more mixture. Thus, the composition of the present invention may contain more than one (B) component, for example, two, three, or four (B) components. For example, the composition may comprise (i) a compound of formula I (particularly Ic), (ii) B1 (or B1a, B1b, B1c, B1d, or B1e), and (iii) B3 (for example, B3a, B3b, B3c, B3d, B3e, B3f, B3g, B3h, B3i, B3j, B3k, B3l, and B3m). Alternatively, the composition may comprise (i) a compound of formula (I), (ii) B2 (or B2a, B2b, B2c), and (iii) B3 (e.g., B3a, B3b, B3c, B3d, B3e, B3f, B3g, B3h, B3i, B3j, B3k, B3l, and B3m). In another embodiment of the invention, the herbicide composition further comprises one or more additional herbicidal components (C).

[0022] According to another aspect of the present invention there is provided a method of controlling weeds in a locus which comprises applying to said locus a weed controlling amount of a composition of the present invention.

[0023] In another embodiment of the present invention, there is provided a method for selectively controlling weeds in a locus comprising a crop plant and a weed, said method comprising applying to said locus a weed-controlling amount of a composition of the present invention. In a preferred embodiment, the crop plant is soybean. In this context, weeds can include, for example, volunteer corn (corn), including genetically modified corn.

[0024] When applied in the compositions of the present invention, component (A) is typically applied at a rate of 25 to 2000 g ha, more specifically, 25, 50, 75, 100, 125, 150, 200, 250, 300, 400, 500, 750, 800, 1000, 1250, 1500, 1800, or 2000 g / ha. Such rates of component (A) are usually applied together with 5 to 2000 g / ha of component B, and more specifically with 5, 10, 15, 20, 25, 50, 75, 100, 120, 125, 140, 150, 200, 240, 250, 300, 400, 480, 500, 750, 1000, 1250, 1500, 1800, or 2000 g / ha of component (B). The examples provided herein illustrate, but do not limit, the rate ranges of components A and B that can be used in the present invention.

[0025] The amount of the composition of the invention that can be applied will depend on various factors such as the compound used; the subject of treatment, such as plants, soil, or seeds; the type of treatment, such as spraying, dusting, or seed dressing; or the time of application. In agricultural practice, the application rate of the composition according to the invention varies depending on the type of effect desired and is usually in the range of 30 to 4000 g of total composition per hectare, and more usually 30 to 2000 g / ha. Application is generally carried out by spraying the composition, typically over a large area with a tractor-mounted sprayer, although other methods, such as dusting (for dusts), drip or drench, can also be used.

[0026] When active ingredients are combined, the expected activity (E) for any given active ingredient combination can be calculated according to the so-called Colby formula as follows (Colby, SR, Calculating synergistic and antagonistic responses of herbicide combination, Weeds, Vol. 15, pp. 20-22; 1967): ppm = mg / L of active ingredient (ai) X=% effect of the first active ingredient using p ppm of active ingredient Y=% effect of the second active ingredient using q ppm of active ingredient.

[0027] According to Colby, the predicted effect of active ingredients A+B using p+q ppm of active ingredients is given by the following formula:

number

[0028] If the actual observed effect (O) is greater than the predicted effect (E), the effect of the combination is superadditive, i.e. synergistic. Mathematically, synergy corresponds to a positive value of the difference (OE). In the case of a purely complementary addition of activity (predicted activity), the difference (OE) is 0. A negative value of the difference (OE) indicates a loss of activity compared to the predicted activity.

[0029] Thus, the combinations of the present invention may utilize any additive herbicidal activity, and certain embodiments may even exhibit synergistic effects, which occurs whenever the action of the combination of active ingredients is greater than the sum of the actions of the individual ingredients.

[0030] The combinations of the present invention may also provide an expanded spectrum of activity compared to the activity provided by each individual component to mediate effective herbicidal activity and / or may allow the use of lower rates of the individual components when used in combination than when used alone.

[0031] It is also possible that the compositions of the invention may show increased crop resistance when compared to the effect of compound A alone. This occurs when the action of the combination of active ingredients is less damaging to useful crops than the action of one of the active ingredients alone.

[0032] Throughout this specification, the expression "composition" should be taken to mean various mixtures or combinations of components (A) and (B) when applied consecutively, i.e., one after the other within a reasonably short period of time, such as a few hours or days, for example in a single "ready-mix" form, combination spray mixtures consisting of separate formulations of a single active ingredient, such as "tank mixes", and combined use of a single active ingredient. The order of application of components (A) and (B) is not essential to the practice of the invention.

[0033] The term "herbicide" as used herein means a compound that inhibits or modifies the growth of plants. The term "herbicidally effective amount" means the amount of such a compound or combination of such compounds that can produce an inhibiting or modifying effect on the growth of plants. Inhibiting or modifying effects include any deviation from natural occurrence, such as death, delay, leaf scorch, chlorosis, shrinkage, etc.

[0034] The term "site" as used herein means the field in which plants are growing or where seeds of cultivated plants are sown or where seeds will be placed in the soil, including the soil, seeds and seedlings, and established vegetation.

[0035] The term "plant" refers to all physical parts of a plant, including seeds, seedlings, saplings, roots, tubers, stems, stalks, leaves and fruits.

[0036] The term "plant propagation material" refers to all reproductive parts of plants, such as seeds or vegetative parts of plants, such as cuttings and tubers. This includes seeds in the strict sense, as well as roots, fruits, tubers, bulbs, rhizomes and plant parts.

[0037] As used herein, the term "safener" means a chemical that, when used in combination with a herbicide, reduces the undesirable effects of the herbicide on non-target organisms; for example, a safener protects a crop from injury by the herbicide but does not prevent the herbicide from killing weeds.

[0038] Crops of useful plants in which the compositions according to the invention can be used include perennial and annual crops, for example berry plants, such as blackberries, blueberries, cranberries, raspberries and strawberries; cereals, such as barley, corn (corn), millet, oats, rice, rye, sorghum, triticale and wheat; fibre plants, such as cotton, flax, hemp, jute and sisal; agricultural crops, such as sugar and fodder beet, coffee, hops, mustard, rapeseed (canola), poppy, sugar cane, sunflower, tea and tobacco; fruit trees, such as apples, apricots, avocados, bananas, cherries, citrus fruits, nectarines, peaches, pears and plums; grasses, such as bermuda grass, bluegrass, bentgrass, centipede grass, fescue, ryegrass, St. Augustine, and other varieties. Examples of weeds that may be used include: laurel grass and turfgrass; herbs such as basil, borage, chives, coriander, lavender, lovage, mint, oregano, parsley, rosemary, sage, thyme; legumes such as beans, lentils, peas and soybeans; nuts such as almonds, cashews, crushed nuts, hazelnuts, peanuts, pecans, pistachios and walnuts; palms such as oil palms; ornamental plants such as flowers, shrubs and trees; other trees such as cocoa, coconut, olives and rubber; vegetables such as asparagus, eggplant, broccoli, cabbage, carrots, cucumbers, garlic, lettuce, marrow, melons, okra, onions, peppers, potatoes, pumpkins, rhubarb, spinach and tomatoes; grapes such as grapes. However, the compositions of the present invention are particularly useful for controlling weeds in cotton or soybean crops, especially soybean crops.

[0039] Crops are to be understood as those occurring in nature, those obtained by traditional breeding methods, or those obtained by genetic engineering, including crops that contain so-called output traits, such as improved storage stability, higher nutritional value and improved flavor.

[0040] Crops should also be understood to include crops that have been made tolerant to herbicides or classes of herbicides (e.g., ALS inhibitors, GS inhibitors, EPSPS inhibitors, PPO inhibitors, ACCase inhibitors, and HPPD inhibitors) by conventional breeding methods or genetic engineering. An example of a crop that has been made tolerant to imidazolinones, such as imazamox, by conventional breeding methods is Clearfield® summer rapeseed (canola). Examples of crops that have been made tolerant to herbicides by genetic engineering include, for example, glyphosate and glufosinate tolerant varieties available under the trade names RoundupReady® and LibertyLink®. Examples of crops that have been made tolerant to PPO-inhibiting herbicides by genetic engineering are known in the art, for example, as described in WO 95 / 34659. Examples of crops that are genetically modified to tolerate HPPD-inhibiting herbicides are known in the art, for example, as described in WO 2011 / 063411, WO 2011 / 063413, WO 2012 / 082542, WO 2012 / 082548, WO 2010 / 085705, and WO 2011 / 068567. The compositions of the present invention that include glufosinate and / or glyphosate are potentially useful in glyphosate- and glufosinate-tolerant crops, respectively, particularly in recombinant soybean crops. The compositions of the present invention that include PPO-inhibiting herbicides are potentially useful in PPO-tolerant crops, particularly in recombinant soybean crops. Compositions of the invention, particularly any that contain 2,4-D (or agronomically acceptable esters or salts thereof), may be useful in crops that have been engineered to tolerate 2,4-D herbicides, such as Enlist™ crops, particularly Enlist E3™ soybeans. Compositions of the invention, particularly any that contain dicamba (or agronomically acceptable esters or salts thereof), may be useful in crops that have been engineered to tolerate dicamba herbicides, such as Roundup Ready 2 Xtend™ soybeans.

[0041] The compositions of the present invention can be used to control a wide variety of monocotyledonous and dicotyledonous weed species in crops. The compositions of the invention are particularly suitable for use with Alopecurus species (e.g. Alopecurus myosuroides (ALOMY)), Avena species, Digitaria species (e.g. Digitaria sanguinalis (DIGSA), Digitaria insularis (TRCIN)), Echinochloa species (e.g. Echinochloa crus-galli (ECHCG)), Eleusine species (e.g. Eleusine indica (ELEIN)), Lolium species, Setaria species (e.g. Setaria faberi (SETFA), and Sorghum sp. (e.g., Sorghum halepense (SORHA). In all aspects of the invention, in any particular embodiment, for example, the weeds to be controlled and / or stunted may be monocotyledonous or dicotyledonous weeds that are tolerant or resistant to one or more herbicides, for example, HPPD inhibitor herbicides such as mesotrione, PSII inhibitor herbicides such as atrazine, or EPSPS inhibitors such as glyphosate.

[0042] Similarly, compositions of the present invention (including those containing one or more additional pesticides) can further contain one or more safety agents. Specifically, the following safety agents are particularly preferred: benoxacor, cloquintocet (including cloquintocet mexyl), cyprosulfamide, dichlormid, fenchlorazole (including fenchlorazole ethyl), fenclorim, fluxofenim, furilazole, isoxadifen (including isoxadifen ethyl), mefenpyr (including mefenpyr diethyl), metcamifen, and oxabetrinil.

[0043] The compositions of the invention can be applied before or after planting of the crop, before the weeds appear (pre-emergence application) or after the weeds appear (post-emergence application).When a safener is combined with the mixture of the invention, the mixture ratio of the compound of formula (I) to the safener is preferably from 100:1 to 1:10, in particular from 20:1 to 1:1.

[0044] The safener and the composition of the present invention can be applied simultaneously. For example, the safener and the composition of the present invention can be applied to the pre-emergence site or to the crop after emergence. The safener and the composition of the present invention can also be applied sequentially. For example, the safener can be applied before sowing the seed as a seed treatment, and the composition of the present invention can be applied to the pre-emergence site or to the crop after emergence.

[0045] The compositions of the invention can be advantageously used, for example, in the formulations described in WO 2015 / 197468. EXAMPLES
