Description

Synergistically acting herbicidal mixtures comprising diquat dibromide and a non-selective herbicide,

The present invention relates to a synergistic herbicidal mixture, more particularly to a synergistic herbicide mixture comprising diquat dibromide and a non-selective herbicide; A herbicidal composition comprising said herbicidal mixture as an active ingredient; And a method for controlling weeds using the same.

In agriculture and pavement management, crop protection from damage from weeds and other plants is a constant challenge for the professional use of homes and gardens. Also, when grass grows in places such as golf courses, lawns and parks, it may be cosmetically important to remove these unwanted weeds and plants. To help solve these problems, researchers in the field of synthetic chemistry have provided a wide variety of chemicals and chemical formulations that are effective in inhibiting such unwanted growth. Many types of chemical herbicides with various modes of action have been disclosed in the literature and many have been used commercially. Commercial herbicides and some herbicides in development are described in The Pesticide Manual (16th edition, 2012, British Crop Protection Council).

There are many classes of manufacturing agents that can be classified based on their mode of operation. One class of herbicide of particular interest is the bipyridylium salt. These compounds inhibit photosystem I (PSI) and are exemplified by paraquat and diquat. Paraquat is marketed under many names in the United States, including Gramoxone and Gramoxone Extra. Paraquat dichloride, a non-selective herbicide, is called Gramoxone and is foliar on weeds. It is a herbicide widely used in Korea. However, these paraquat herbicides have been used for suicide, and currently pesticide registration has been abolished in Korea.

Glyphosinate ammonium, also known as another herbicide active ingredient, is a non-selective herbicide. It is known to have herbicidal effects throughout the light and foliage and weeds. When the herb is grown at 20 to 30 cm, it is most effective when sprayed. Only the leaves and stalks that have been buried are damaged. Glucosinate ammonium is known to decompose in soil 10-14 days under outdoor packaging conditions. However, these ammonium gluconate are relatively expensive and widely used herbicides, while the herbicidal effect is very slowly expressed, which is problematic for use as an effective weed control agent. To solve this problem, efforts have been made to efficiently control weeds in combination with ammonium gluconate.

On the other hand, in general, there is little difference in effectiveness between using herbicides individually (only zero) and using them in combination (in some cases), but in some cases the herbicidal active ingredients are mixed with other herbicides than when used individually There is a case where the effect is further increased. The case in which the efficacy or the activity level above a predictable level according to the result of the individual efficacy of the constituent component is referred to as "synergistic action ". However, the synergistic action of herbicides when mixing two or more herbicidal active substances is extremely limited. In contrast, the herbicidal activity of the two herbicides is lower than that of the single treatment due to the difference in herbicidal properties, absorption, many. The case where the herbicidal effect is lowered when the two herbicidal active substances are mixed with each other as compared with the case of the single treatment, is referred to as "antagonistic action ". In addition, the herbicidal effect when the herbicidally active substance is mixed is referred to as " additive action "

Accordingly, the present inventors have sought to find a solution to the problem of the slowly emerging herbicidal activity of ammonium gluconate as a herbicidal active ingredient widely used in Korea. As a result, it has been found that the use of a growth regulator Herbicidal mixtures of diquat dibromide and ammonium gluconate in a specific ratio as a diquat system component having a fast-acting (similar to herbicidal activity) property similar to the registered paraquat, The herbicidal activity of the herbicide of 80% or more in plants, the herbicidal activity of 30 days or more, and the fast herbicidal activity in the average of 54 to 78 hours (about 2 to 3 days).

Korean Patent No. 10-0616040 Korean Patent Publication No. 10-2013-0132933 Korean Patent Publication No. 10-2013-0101039 Korean Patent Publication No. 10-2005-0114651

The invention is characterized by a synergistic herbicide mixture comprising diquat dibromide and a non-selective herbicide, wherein said non-selective herbicide is preferably glufosinate ammonium.

In the present invention, the diquartz dibromide is a diquaternary compound, which is currently used as a desiccant in accordance with the characteristics of a pesticide registered as a use of a growth regulator (not a herbicide application) . These diacetate dibromide compounds have the property of killing mitochondria through N-and O- ₃ production, which are cytotoxic depending on sunlight depending on the mechanism of inhibiting PSI, so that chemical reaction depends on sunlight Lt; RTI ID = 0.0 > plants < / RTI >

In the present invention, the ammonium gluconate is a herbicide widely used as a herbicide for domestic pesticide, which is a relatively expensive and registered ingredient. These glufosinate ammoniums have a tendency to increase the accumulation of ammonia toxicity with temperature (depending on the temperature) when the plant is treated, and the herbicidal effect is gradually exhibited. Therefore, when the temperature is low, in winter or in a short time, There is a problem in using it as an effective weed control agent.

As used herein, the term " herbicide " refers to a compound that inhibits or modulates the growth of a plant, and the term " herbicide mixture " refers to a mixture of two or more compounds that inhibit or modulate plant growth .

The term " non-selective " as used herein means that the plant species in which the herbicide is active are not selective and have activity against all plant species. The term " plant " as used in the present invention is also a concept that includes all physical parts of a plant including seed, seedling, seedlings, roots, tubers, stems, leaves, and fruits.

As used herein, the term " synergistic " refers to a property that exhibits a level of activity that is better than would be expected based on knowledge of the individual efficacy of the components.

Thus, the " synergistic herbicide mixture " of the present invention is defined as a mixture of herbicides which exhibit an unexpectedly high level of activity compared to the respective efficacy of diquat dibromide and ammonium gluconate as the respective constituents of the mixture .

In one embodiment of the present invention, the synergistic herbicide mixture may be a herbicide mixture comprising diquat dibromide and ammonium gluconate as active ingredients (active ingredient), especially diquat dibromide, It is preferred that the weight ratio of the contrast glufosinate ammonium has a composition ratio of 2: 1 to 5: 1.

The present invention also provides a synergistic herbicidal composition comprising said synergistic herbicidal mixture as an active ingredient.

In one embodiment of the present invention, the composition comprises 10 to 20% by weight of diquarty dibromide and 2 to 10% by weight of ammonium gluconate based on 100% by weight of the composition of diquart dibromide and ammonium gluconate, Preferably, diquat dibromide and ammonium gluconate are mixed in a weight ratio of 15: 4.

In another embodiment of the present invention, the herbicide composition is selected from the group consisting of agriculturally acceptable carriers, organic solvents, defoamers, preservatives, antifreeze agents, pH adjusting agents, colorants and other adjuvants in addition to the synergistic herbicide mixture And may further include at least one kind thereof.

The herbicidal composition may be prepared by mixing diquat dibromide and ammonium gluconate compound with an appropriate carrier and a diluent in a suitable formulation such as an emulsion, a wetting agent, a powder, a granule, etc. Preferably, A liquid agent in which water is used as a solvent is suitable, but some changes are possible depending on the use purpose of the preparation.

Suitable carriers for use in the composition according to the invention are liquid carriers and solid carriers. Examples of the liquid carrier include water, alcohols (monohydric alcohols such as methanol, dihydric alcohols such as ethylene glycol, trihydric alcohols such as glycerin), ketones (such as acetone and methyl ethyl ketone), ethers (such as dioxane, tetrahydrofuran, Etc.), aliphatic hydrocarbons (such as gasoline and kerosene), halogenated hydrocarbons (such as chloroform and carbon tetrachloride), acid amides (such as dimethylformamide), esters (such as ethyl acetate, butyl acetate and fatty acid glycerin ester) Nitrile, etc. In the present invention, these may be used alone or in combination of two or more. As the solid carrier, other mineral particles other than mineral particles (kaolin, clay, bentonite, acidic clay, talc, silica, sand, etc.) and vegetable powders (woody) can be used.

The herbicide compositions of the present invention are often formulated and distributed in concentrated form and may be diluted by the user prior to use. A small amount of a surfactant carrier facilitates this dilution process. Therefore, at least one of the carriers used in the herbicidal composition according to the present invention may be a surfactant. For example, the herbicide compositions of the present invention may contain at least two carriers, at least one of which may be a surfactant.

The surfactant may be a dispersant or a penetrant and the surfactant may be ionic or non-ionic. Examples of the surfactant include sodium or calcium salts of polyacrylic acid and lignin sulfonic acid; Condensation products of fatty acids or aliphatic amines or amides containing at least 12 carbon atoms in the molecule with ethylene oxide and / or propylene oxide; Fatty acid esters of glycerol, sorbitan, sucrose or pentaerythritol; Ethylene oxide and / or propylene oxide and condensates thereof; fatty alcohols or alkyl phenols such as condensation products of p-octylphenol or p-octylcresol with ethylene oxide and / or propylene oxide; Sulfates or sulfonates of these condensation products; Alkaline or alkaline earth metal salts of sulfuric acid or sulfonic acid esters containing at least 10 carbon atoms in the molecule, preferably sodium salts such as sodium lauryl sulphate, sodium secondary alkyl sulphate, sodium sulphonated castor oil, Sodium alkylaryl sulfonates such as benzenesulfonate; And polymers of ethylene oxide and copolymers of ethylene oxide and propylene oxide.

<1-5> Summary of results

All of the test medicines showed similar efficacy against the annual and perennial weeds occurring on the non-agricultural land, compared with the control medicines. As a result, all of the test medicines had short-term effects on annual and perennial weeds It was judged to be practicable in controlling the efficacy. Currently, the drug efficacy is present in Korea at the same time, and since there is no medicine having a long duration of drug efficacy, the above-mentioned combination having long-lasting properties in such a zone area can be usefully used for herbicidal purposes.

In particular, as shown in Table 20, as a result of controlling the efficacy against perennial weeds and perennial weeds according to 35 days after the treatment, the composition ratio of diquat dibromide and glufosinate ammonium was 18: 2 wt% Showed more than 80% inhibition in all experimental groups.
