Description

Technical Field

[0001] This invention relates to a mixture comprising the active ingredients of dimethyl phenoxychloride and fluthiamethoxam, and to methods for controlling weeds, including the application of the mixture. Background Technology

[0002] Crop susceptibility to weed damage makes crop protection management a key component of the entire crop production system. Various insects and fungi, along with unwanted weeds, are extremely harmful to crop plants and can significantly reduce crop yield and quality. Herbicides, alone or in combination, help minimize this damage by controlling the threat to crops. For these purposes, many active ingredients of the same class or mixtures of different classes are commercially available.

[0003] Combinations of herbicides, or mixtures of one or more herbicides with other active ingredients, are typically used to broaden the control spectrum through addition effects, minimize the dosage of chemicals used, delay the development of resistance, and reduce treatment costs. Although many combinations of a herbicide with one or more active ingredients have been studied, synergistic effects are rarely observed.

[0004] Practical agricultural experience has shown that, in controlling a single weed, repeated and specific application of an individual active ingredient often results in the selection of weeds that have developed natural or adaptive resistance to the active compound in question. Effective control of these weeds with the active compound in question then becomes impossible.

[0005] Therefore, active ingredients that help prevent or overcome resistance are needed. To reduce the risk of weeds developing resistance to certain active compounds, mixtures of different active ingredients are now commonly used to control weeds. By judiciously combining active compounds with different mechanisms of action, successful control can be ensured over a relatively long period.

[0006] Active agent mixtures are described in the literature. However, weed control does not always meet the needs of agricultural practices. Furthermore, the control efficacy provided by these mixtures is not always satisfactory, or may produce additional toxicological and / or environmental impacts. Randomly formulated pest control agents and mixtures do not achieve satisfactory control effects in most cases, and therefore, there is an urgent need to develop new pest control mixtures with satisfactory control effects using more than one active ingredient.

[0007] The object of this invention is to provide mixtures and formulations of intelligently selected active ingredients that exhibit improved activity against harmful weeds. The object of this invention is to provide mixtures and formulations that demonstrate synergistic control over weeds. Summary of the Invention

[0008] This invention aims to find mixtures that provide improved weed control. These improvements can manifest as synergistic effects between active ingredients. That is, allowing for better weed control than might be achieved by using individual compounds alone. The improvements can also overcome at least one challenge in the prior art, for example, by reducing dosage rates, or by enhancing the activity spectrum, or by combining knockdown activity with long-term control, or by promoting resistance management.

[0009] In view of the above, the object of the present invention is to provide a mixture of active ingredients for improving weed control.

[0010] The object of the present invention is to provide a mixture comprising dimethoprim, its ester or salt, and fluthiamethoxam, its ester or salt.

[0011] The present invention provides a composition wherein the weight ratio between dimethoprim and fluthiamethoxam is typically 1:20 to 20:1, for example 1:1 to 10:1 or 1:1 to 5:1, and the amount of each active ingredient is about 0.1-99 wt.%, about 0.1-95 wt.%, or about 0.1-90 wt.% based on the total weight of the mixture composition.

[0012] The present invention provides a mixture comprising dimethoprim, its ester or salt as described above, and fluthiamethoxam, its ester or salt, wherein the application rate of the mixture according to the present invention is from 1 g / ha to 1000 g / ha, wherein “g / ha” has its standard meaning, i.e., grams of active ingredient per hectare.

[0013] The present invention further provides a formulation comprising dimethoprim, its ester or salt, and fluthiamethoxam, its ester or salt, as described above, and further comprising at least one agriculturally acceptable additive, for example, at least one selected from the group consisting of a carrier, a surfactant, a solvent, and combinations thereof.

[0014] The present invention further provides the use of mixtures or formulations comprising dimethochlor, its esters or salts, and fluthiachlor, its esters or salts, for the control of weeds.

[0015] The present invention also provides a method for controlling weeds, the method comprising contacting the weeds or their location with an agriculturally effective amount of a mixture or formulation according to the present invention. Detailed Implementation

[0053] Preparations

[0054] Therefore, for example, the mixtures of the present invention can be applied in a single "ready-to-use" form or as a combined spray mixture (which consists of separate formulations of each single active ingredient) such as a "bucket mix". This premixed formulation can be obtained by combining an effective amount of the active ingredient with an agriculturally acceptable carrier, surfactant, or other application-promoting adjuvants commonly used in formulation techniques.

[0055] The mixtures of the present invention may contain at least one additional component selected from the group consisting of surfactants, solid diluents, and liquid diluents. Such compositions may be formulated using agriculturally acceptable carriers, surfactants, or other application-promoting adjuvants commonly used in formulation techniques, as well as formulation techniques known in the art.

[0056] Examples of suitable solid carriers that may be used in the compositions of the present invention include, but are not limited to, minerals such as silica gel, silicates, talc, kaolin, sericite, attaclay, limestone, bentonite, lime, chalk, red basalt, mirabilite, loess, clay, dolomite, zeolite, diatomaceous earth, calcium carbonate, calcium sulfate, magnesium sulfate, magnesium oxide, sodium carbonate and sodium bicarbonate, and sodium sulfate; pulverized synthetic materials; fertilizers such as ammonium sulfate, ammonium phosphate, ammonium nitrate, urea, and plant-derived products such as cereal powder, bark powder, wood powder, and nut shell powder; cellulose powder; and other solid carriers.

[0057] Examples of suitable liquid carriers that may be used in the compositions of the present invention include, but are not limited to, water; aromatic hydrocarbons such as alkylbenzenes and alkylnaphthalenes; alcohols such as cyclohexanol and decanol; ethylene glycol; polypropylene glycol; dipropylene glycol; N,N-dimethylformamide; dimethyl sulfoxide; dimethylacetamide; N-alkylpyrrolidones such as N-methyl-2-pyrrolidone; alkanes; various oils such as olive oil, castor oil, linseed oil, tung oil, sesame oil, corn oil, peanut oil, cottonseed oil, soybean oil, rapeseed oil, or coconut oil; fatty acid esters; ketones such as cyclohexanone, 2-heptanone, isophorone, and 4-hydroxy-4-methyl-2-pentanone; and so on.

[0058] The compositions of this invention can be used or prepared in any conventional form, such as as wettable powder (WP), emulsion concentrate (EC), microemulsion concentrate (MEC), water-soluble powder (SP), water-soluble concentrate (SL), suspension (SE), oil dispersion (OD), concentrated emulsion (BW) such as oil-in-water and water-in-oil emulsions, sprayable solutions or emulsions, capsule suspension (CS), suspension concentrate (SC), suspension concentrate, powder (DP), oil-miscible solution (OL), seed dressing products, granules (GR) in the form of microparticles, spray granules, coated granules and absorbent granules, granules for soil application or broadcasting, water-soluble granules (SG), water-dispersible granules (WDG), ULV formulations, microcapsules or waxes. These individual formulation types are known in the art.

[0059] Examples of suitable surfactants include, but are not limited to, nonionic, anionic, cationic, and amphoteric surfactants such as alkoxylated fatty alcohols, ethoxylated polysorbates (e.g., Tween 20), ethoxylated castor oil, lignin sulfonates, fatty acid sulfonates (e.g., lauryl sulfonates), phosphate esters (e.g., phosphate esters of alcohol alkoxylates, phosphate esters of alkylphenol alkoxylates, and phosphate esters of styrylphenol ethoxylates), condensates of sulfonated naphthalene and naphthalene derivatives with formaldehyde, condensates of naphthalene or naphthalene sulfonic acid with phenol and formaldehyde, alkylaryl sulfonates, ethoxylated alkylphenols and arylphenols, polyalkylene glycols, sorbitol esters, alkali metal salts and sodium salts of lignin sulfonic acid, tristyrylphenol ethoxylate phosphate esters, aliphatic alcohol ethoxylates, alkylphenol ethoxylates, ethylene oxide / propylene oxide block copolymers, graft copolymers, and polyvinyl alcohol-vinyl acetate copolymers.

[0061] Aqueous forms can be prepared by adding water from emulsion concentrates, suspensions, pastes, wettable powders, or water-dispersible particles. To prepare emulsions, pastes, or oil dispersions, the composition components, either as is or dissolved in oil or solvent, can be homogenized in water using a wetting agent, thickener, dispersant, or emulsifier. Alternatively, concentrates containing active ingredients, wetting agents, thickeners, dispersants, or emulsifiers, and, where necessary, solvents or oils, can be prepared; these concentrates are suitable for dilution with water.

[0062] Typically, the concentration of the active ingredient in the formulation is about 0.1-99 wt.%, about 0.1-95 wt.%, or about 0.1-90 wt.% based on the total weight of the formulation. For example, the concentration of the active ingredient in the formulation is about 1-70 wt.% based on the total weight of the formulation, for example, about 1-50 wt.%, or about 1-40 wt.%, or about 1-30 wt.% or about 1-20 wt.% based on the total weight of the composition. For example, the concentration of the active ingredient in the formulation can be about 1-10 wt.% based on the total weight of the formulation. Thus, for example, the concentration of the active ingredient in the formulation can be from about 0.1%, 0.5%, 1%, 1.5%, 2%, 2.5%, 3%, 3.5%, 4%, 4.5%, 5% to about 90%, 93%, 95%, 98%, 99% based on the total weight of the formulation. The remaining components in the formulation are, for example, carriers and additives.

[0063] Alternatively, the present invention provides a kit comprising dimethoprim, its ester or salt, and fluthiamethoxam, its ester or salt. Such a kit may also contain one or more additional active ingredients, either within or separately from the provided pest-killing composition, in addition to the aforementioned active ingredients.

[0064] How to use

[0065] The present invention provides a method for controlling weeds by contacting the weed or its location with an effective amount of any of the mixtures or compositions disclosed herein, so as to control the weeds thereby.

[0066] The following representative examples illustrate the practice of the invention in some of its embodiments, but should not be construed as limiting the scope of the invention. Other embodiments will be apparent to those skilled in the art based on consideration of the specification and examples.

[0067] Representative examples

[0068] A synergistic effect exists when the combined effect of the active ingredients is greater than the sum of the effects of the individual components. In agriculture, the term "synergistic effect" should generally be understood as defined by Colby SR in his article entitled "Calculation of the synergistic and antagonistic responses of herbicide combinations," published in the journal *Weeds*, 1967, 15, pp. 20-22. The expected effect for a given combination of two active ingredients can be calculated by Colby as follows:

[0069] E = A + B - AB / 100

[0070] Where E represents the expected effect of a combination of active ingredients at a defined dose (e.g., equal to x and y, respectively), such as pest control percentage; A represents the effect observed at a defined dose (e.g., equal to x), for a first compound or mixture of compounds, such as pest control percentage; and B represents the effect observed at a defined dose (e.g., equal to y), for a second compound or group of compounds, such as pest control percentage.

[0071] Here, efficacy or inhibition percentage is defined as %. 0% means efficacy corresponding to the control, i.e., as if no treatment was applied. 100% inhibition percentage means that complete control was observed. A synergistic effect exists when the observed percentage of control (E0) for the combination is greater than E. An additive effect exists when the observed percentage of control (E0) for the combination is equal to E, and an antagonistic effect exists where the observed percentage of control (E0) for the combination is less than E.

[0072] Example 1: Pot experiment using AMARE with dimethyl phenoxychloride-P + fluthiamethoxam

[0073] Bucket mixtures were prepared by combining formulations with water to achieve the desired concentrations of each active ingredient, as outlined in Table 1. For this study, individual pots were used to sow weeds, each containing the weed AMARE (Amaranthus retroflexus). Treatments were then applied to each pot before weed emergence, ensuring consistent timing of application for all treatments. A comprehensive evaluation was subsequently conducted eight days post-application (8DAA) to assess the efficacy of each treatment against the AMARE weed species. The results obtained from this evaluation are summarized in Table 1.

[0074] Table 1: Test Treatment

[0075]

[0076] We wanted to test whether mixing fluthiamethoxam and dimethoprim-p would produce a greater effect than the sum of the effects of each of the individual active ingredients. For this, we used the Colby equation. If the observed value of the mixture is greater than expected, we can conclude that the two chemicals have a synergistic effect when combined.

[0077] Fluthiamethoxam showed 0% efficacy against AMARE, while dimethoprim-p showed 75% efficacy against AMARE. When we mixed fluthiamethoxam and dimethoprim-p in a tank, we observed 100% efficacy. The expected efficacy (E) of the mixture was calculated to be 75% (calculated in Table 2).

[0078] Table 2: Colby Calculation

[0079]

[0080] The results clearly demonstrate that when fluthiamethoxam and dimethoprim-p are mixed in the tank (treatment 3, table 1), they provide synergistic control of broadleaf weeds such as AMARE and others, compared to the use of either active ingredient alone (treatment 1 or 2, table 1).

[0081] Example 2: Pot experiment on LOLPE using fluthiamethoxam + dimethoate-p

[0082] Bucket mixtures were prepared by combining formulations with water to achieve the desired concentrations of each active ingredient, as outlined in Table 3. For this study, individual pots were used to sow weeds, with each pot containing one weed species, such as LOLPE (Lolium perenne). Treatments were then applied to each pot before weed emergence, ensuring consistent timing of application for all treatments. A comprehensive evaluation was then conducted 14 days post-application to assess the efficacy of each treatment on LOLPE. The results obtained from this evaluation are summarized in Table 3.

[0083] Table 3: Test Treatment

[0084]

[0085] Colby equation:

[0086] We wanted to test whether mixing fluthiamethoxam and dimethoprim-p would produce a greater effect than the sum of the effects of each of the individual active ingredients. For this, we used the Colby equation. If the observed value of the mixture is greater than expected, we can conclude that the two chemicals have a synergistic effect when combined.

[0087] Fluthiamethoxam showed 0% efficacy against LOLPE, while dimethoprim-p showed 30% efficacy against LOLPE. The expected efficacy (E) of the mixture was 30% (calculated in Table 4). When we mixed fluthiamethoxam and dimethoprim-p in a tank, we observed 50% efficacy.

[0088] Table 4: Colby Calculation

[0089]

[0090] The results clearly demonstrate that when fluthiamethoxam and dimethoprim-p are mixed in the tank (treatment 3, table 3), they provide synergistic control of grass weeds (LOLPE and others) compared to using either active ingredient alone (treatment 1 or 2, table 3).
