FIELD OF THE INVENTION

The present invention relates to a herbicidal mixture for controlling undesirable vegetation. In particular, the present invention relates to a herbicidal mixture comprising a synergistic combination of propaquizaphop and imazetapir.

State of the art

Control of unwanted vegetation is critical to achieving high crop efficiency. In many cases, herbicides are effective against a number of weeds; however, these herbicides may be ineffective against certain types of weeds, which may also be present in crops requiring protection. Thus, there is an urgent need for mixing two or more herbicides.

Mixtures of selected herbicides have several advantages over using a single herbicide, including (a) increasing the range of controlled weeds or extending the control of weeds for a longer period of time; (b) increasing the safety of crops using the minimum doses of selected herbicides used in combination, compared with a high dose of a single herbicide; and (c) slowing down the appearance of weed species resistant to selected herbicides (Int. J. Agri. Biol., Vol. 6, No. 1, 2004, p, 209-212).

However, the activity and selectivity of the mixture is difficult to predict, since the behavior of each individual herbicide is often influenced by the presence of the other (s), and the activity of the mixture can also vary significantly depending on the chemical nature, plant species, growth stage and environmental conditions; this leads mainly to a decrease in the activity of herbicides in the mixture.

Propacquisaphop, ((R) -2 - [[(1-methylethylidene) amino] oxy] ethyl 2- [4 - [(6-chloro-2-quinoxalinyl) oxy] phenoxy] propanoate), disclosed in US 4,545807, is an inhibitor fatty acid synthesis, which inhibits acetyl CoA carboxylase (AKKase). It is a systemic post-emergence herbicide, absorbed by foliage and roots, and transported by the plant. Propacquisaphop is used to control a wide range of annual and perennial herbs (including Sorghum halepense, Agropyron repens and Cynodon dactylon) in crops of soy, cotton, sugar beets, potatoes, peanuts, peas, oilseed rape and vegetables.

Imazetapyr, (RS) -5-ethyl-2- (4-isopropyl-4-methyl-5-oxo-2-imidazolin-2-yl) nicotinic acid, disclosed in US 4,798,619, is a branched chain amino acid synthesis inhibitor (inhibitor ALS or AHAS). It causes a decrease in the levels of valine, leucine and isoleucine, which leads to impaired protein and DNA synthesis. Imazetapir is a systemic herbicide absorbed by roots and leaves. Imazetapir controls many of the major annual and perennial grasses and broadleaf weeds.

According to the Compatibility Table of Herbicide Blends published by the Government of Western Australia, the Department of Agriculture and Food, mixing imazetapir and propaquizaphop is not recommended. The table indicates that a combination of both herbicides may cause excessive damage to crops or reduced weed control [www.agric.wa.gov.au/objtwr/imported_assets/content/pw/weed/herbicide%20compatibility%20chart.pdf].

In addition, Paul F. Myers and Harold D. Coble (Weed Technology Vol. 6, No. 2, 1992, pp. 333-338) indicate that tank-mixed combinations of imazetapir with celodime, fluazifop-P, chisalophop or setoxime, all of which are inhibitors of acetyl CoA carboxylase, like propaquizaphop, lead to antagonistic interactions.

The compositions described can be prepared at the time of use, or diluted, or they can also be concentrated compositions, or so-called “ready-to-use” compositions, i.e. ready for sale.

In one embodiment, the formulation may be prepared by combining a synergistic amount of the active ingredients with an agronomically acceptable carrier, surfactant or other adjuvant-promoting adjuvant commonly used in formulation technology.

In another embodiment, the composition may be used in any conventional form, for example, in the form of a double package, or emulsion concentrates (CE), microemulsion concentrates (CME), suspension concentrates (COP), soluble concentrates (PK), suspoemulsion (SE), oil dispersions (MD), water-dispersible granules (DVG), water-soluble granules (RG) and wettable powders (SP). Such compositions may be formulated using agronomically suitable carriers, surfactants, or other adjuvants that promote the use of adjuvants commonly used in formulation technology and formulation techniques known in the art.

In a specific embodiment, the composition of imazetapir and propaquizaphop is an emulsion concentrate, preferably a microemulsion.

In one embodiment, the amount of the mixture of the active ingredient in the composition may be about 0.1-99 mass. %, preferably about 0.1-95 mass. %, more preferably, about 0.1-90 mass. % based on the total weight of the composition. In another embodiment, the amount of the mixture of the active ingredient in the composition may be about 0.1-50 mass. %, preferably about 0.1-25 wt. %, more preferably, about 0.1-10 mass. % based on the total weight of the composition.

Examples of suitable liquid carriers for use in the composition may include water, aromatic hydrocarbons such as alkylbenzenes and alkylnaphthalenes, alcohols such as methanol, cyclohexanol and decanol, ethylene glycol, propylene glycol and dipropylene glycol, N, N-dimethylformamide, dimethyl sulfoxide, N-alkylpyrrolide , oils from olives, castor oil, flax, tung, sesame, corn, peanuts, cotton, soy, rape and coconut; fatty acid esters, ketones such as cyclohexanone, 2-heptanone, isophorone and 4-hydroxy-4-methyl-2-pentanone and the like.

Examples of suitable solid carriers for use in the composition may include natural minerals such as silica gels, silicates, talc, kaolin, attapulgite, limestone, lime, chalk, bol, loess, clay, dolomite, diatomaceous earth, calcium sulfate, magnesium sulfate, magnesium oxide sodium carbonate and bicarbonate; and sodium sulfate, milled synthetic materials; fertilizers, for example, such as ammonium sulfate, ammonium phosphate, ammonium nitrate, urea; and plant foods such as cereal flour, cinchona flour, wood flour and chopped nutshells, cellulosic powders and other solid carriers.

Examples of suitable surfactants include nonionic, anionic, cationic and ampholytic types, such as alkoxylated fatty alcohols, ethoxylated polysorbate (e.g., Tween-20), ethoxylated castor oil, lignin sulfonates, fatty acid sulfonates (e.g. lauryl sulfonate), phosphate esters such alcohol alkoxylate phosphate esters, alkyl phenol alkoxylate phosphate esters and styryl phenol ethoxylate phosphate esters; sulfonated naphthalene condensates and naphthalene derivatives with formaldehyde, naphthalene or naphthalenesulfonic acid condensates with phenol and formaldehyde, alkylaryl sulfonates, ethoxylated alkyl phenols and aryl phenols, polyalkylene glycols and sorbitol esters.

In another embodiment, a kit comprising a herbicidal mixture as described herein, or components thereof, is provided. Such kits may contain, in addition to the aforementioned active ingredients, one or more additional active and / or inactive ingredients, as part of the provided herbicidal composition or separately. Some kits contain imazetapir, propaquizafop, each in a separate container, and each optionally combined with a carrier.

A synergistic effect exists when the action of a combination of active components exceeds the sum of the effects of each component individually. Thus, a synergistically effective amount (or an effective amount of a synergistic composition or combination) is an amount that provides greater pesticidal activity than the sum of the pesticidal activities of the individual components.

In the field of agriculture, it is often implied that the term “synergism” is as defined by Colby S.R. in an article entitled "Calculation of the synergistic and antagonistic responses of herbicide combinations" ("Calculation of the synergistic and antagonistic response for herbicide combinations"), published in the journal Weeds, 1967, 15, p. 20-22, incorporated by reference in its entirety. The action expected for this combination of two active components can be calculated as follows:

where E represents the expected percentage of pesticidal control for a combination of two pesticides at specific doses (e.g., equal to x and y, respectively), X is the percentage of herbicidal control observed for imazetapir at a specific dose (equal to x), and Y is the percentage of herbicidal control observed for propaquizaphop at a specific dose (equal to y). When the percentage of herbicidal control observed for the combination exceeds the expected percentage, a synergistic effect is observed, when the percentage of control observed for the combination is equal to the expected percentage, the additive effect is observed, and when the percentage of herbicidal control observed for the combination is lower than the expected percentage, the antagonistic Effect.

Experiment Details

Recipe Example

One embodiment of a formulation of a ready-mixed emulsion concentrate used as an example is shown in Table 1 below.

The above formulation was prepared by preparing a mixture containing 37.5 g of imazetapir, surfactants, additives and dipropylene glycol, propylene glycol and water as solvents. After that, a preliminary mixture of 25 g of propaquizaphop dissolved in Solgad 200 ULN was added to the mixture. Then the mixture was stirred until smooth.

The experiments

The experiments were carried out by mixing in a tank commercial Agil (propakvizafop 10% KE, 100 g / l) and commercial Weedlock (imazetapir 10% RK, 100 g / l) using soy, mungo beans, peanuts (peanuts), kayanus (pigeon peas), Turkish peas, beans, fodder peas and guar (tables 2-10) with different levels of application.

The application was carried out using a knapsack spray equipped with a flat nozzle for the application of herbicides. The design of the experiment was arbitrary blocks with three replicates and nine treatments.

Weeds were counted at 15 and 30 DPO (days after treatment) using weeds on a 0.25 m ² quadrant in at least 3 places randomly selected on the plot / repetition. The average value of each variable was used together with the sum of all variables per plot to calculate the percentage of control.

The observed% control was calculated as follows:

Observed% control = ((average number of weeds in the untreated control - average number of weeds in the treated area) / average number of weeds in the untreated control) × 100.
