    Description

    FIELD OF THE INVENTION



    [0001] Some aspects of the invention relate to emulsions which include fungicides and are suitable for use in agriculture.

    BACKGROUND AND SUMMARY



    [0002] Liquid pre-mix concentrates containing two or more active ingredients are useful in a wide variety of agricultural applications. For example, two or more pesticidal active ingredients may be combined in order to control a wider spectrum of pests, or to utilize multiple modes of action, compared to the individual active ingredients alone.

    [0003] Water insoluble pesticide active ingredients may be formulated in water as aqueous suspension concentrates (SC) or by dissolving the water insoluble pesticide in an organic solvent and forming an emulsifiable concentrate (EC). The preparation of these liquid, pre-mix concentrates can be challenging owing to chemical and/or physical instability issues.

    [0004] Emulsifiable concentrate formulations, also known as emulsion concentrates or ECs, are widely used in crop protection, see e.g. WO 2013/126948 A1 and WO 2013/126947 A1. Pesticidal compositions comprising picolinamide derivatives are disclosed e.g. in US 7,183,278 B1, WO 2011/044213 A1, US 2012/0035054 A1 and US 7,250,389 B1. The disadvantages of some emulsifiable concentrates include their poor cold temperature stability and the pronounced tendency of the active ingredient to crystallize, owing to the low solubility of some active ingredients in the concentrate. It was an object of the present disclosure to provide a method of controlling plant derived fungal pathogens or diseases with an emulsifiable concentrate which overcomes these disadvantages.

    [0005] Provided and claimed herein is a method of controlling plant derived fungal pathogens or diseases comprising contacting the vegetation or an area adjacent thereto to prevent the growth of the fungal pathogens or diseases with a fungicidally effective amount of a fungicidal composition comprising:
    1. a) a fungicidal compound of the Formula

    2. b) at least one ionic surfactant;
    3. c) at least one nonionic surfactant;
    4. d) from 50 ± 5 g/L to 700 ± 70 g/L of benzyl acetate;
    5. e) at least one N,N-dialkylcarboxamide; and
    6. f) from 25 ± 2.5 g/L to 150 ± 15 g/L of at least one of a ketone and an alcohol selected from the group consisting of: cyclohexanone, acetophenone, 2-heptanone, 2-heptanol, oleyl alcohol, and 2-ethylhexanol.


    [0006] In certain embodiments, the described fungicidal composition used in the claimed method may include a second fungicidal compound.

    [0007] In certain embodiments, the acetate ester, the N,N-dialkylcarboxamide and the at least one of a ketone and an alcohol together form a water immiscible organic solvent for the described fungicidal composition used in the claimed method.

    [0008] In certain embodiments, the described fungicidal composition used in the claimed method forms a stable, homogenous emulsifiable concentrate that readily emulsifies and forms a stable emulsion without crystallization of the fungicidal compound when added to water.

    [0009] In certain embodiments, the described composition used in the claimed method may include an adjuvant that improves the fungicidal performance of the composition.

    [0010] In certain embodiments, the described composition used in the claimed method may include additional active ingredients and/or inert formulation ingredients.

    Example 2: Solubility of Fungicidal Active Ingredients in Organic Solvents



    [0102] 
    a) Relative solubility of Compound A and prothioconazole in organic solvents with low solubility in water.
    To prepare an effective EC composition containing Compound A and prothioconazole the following solvent attributes must be achieved:
    • Compound A solubility needs to be above 10 wt%
    • prothioconazole solubility needs to be above 20 wt%
    • water solubility of solvent candidates should be below about 5g/L or 0.5% so that good emulsion stability will be achieved when the EC is added to water

    Test method: The approximate solubility of Compound A was determined by mixing a known mass of the active ingredient with an increasing mass of each solvent at ambient temperature. For example, 0.2g of Compound A was mixed with 1.38g of cyclohexanone giving a clear solution containing 12.6% w/w Compound A. Cyclohexanone was therefore classified as a very good solvent for Compound A as it offered "High" solubility (see following table) and was included for further evaluation. The solubility of Compound A in the solvents used in this screening procedure was generally classified within the following concentration ranges:
    Compound A Solubility (wt%)Relative Solubility
    >8.4 High
    8.4 to 5.6 Medium
    5.6 to 3.0 Low
    < 3.0 Very Low
    Prothioconazole Solubility (wt%)Relative Solubility
    >30 High
    >20 to 30 Medium
    10 to 20 Low
    < 10 Very Low

    Table 9 shows the relative solubility of Compound A and prothioconazole in a variety of organic solvents.

    b) Solubility of Compound A and prothioconazole in benzyl acetate/AMD810 blends at 10°C.
    A study of the Compound A and prothioconazole solubility in blends of benzyl acetate / AMD810 was conducted. To each solvent blend both actives were added until each was saturated and the resulting mixtures were then stored at 10°C until equilibrium was obtained. Aliquots of the supernatant layer were taken from each sample, filtered (0.45µm mesh) and analyzed by HPLC to determine the solution concentration of each active in the blends. Table 10 shows the results.

    c) Solubility of Compound A and prothioconazole in benzyl acetate / AMD810 / cyclohexanone blends at 10°C.
    The weight fraction of each solvent was tested at a variety of levels (from 0 to 1) in the various blends shown in Table 11. A total of 20 g of each solvent blend was prepared per sample. For example, one of the blends (Blend 4) was prepared by combining cyclohexanone 0.2 (4g), benzyl acetate 0.2 (4g) and AMD810 0.6 (12g). To Blend 4 were added amounts of Compound A and prothioconazole technical active ingredients to achieve saturation concentrations of each. The samples were then stored at 10°C for one week and then were analysed for soluble active ingredient content. The results are shown in Table 11.

    [0106] Disease control using described compositions containing Compound A and, optionally, either prothiconazole or pyraclostrobin, before and after a simulated rain event to evaluate rainfastness of the applied compositions.

    [0107] Methods: 'Yuma' wheat was used as the host plant in these fungicide efficacy trials. Seedlings were sprayed when the second leaf was fully expanded (8 days after seeding). The fungus Puccinia triticina (PUCCRT; wheat brown rust) was used as the test organism in the efficacy bioassay. The amount of rain applied after fungicide applications was 10 mm. Four separate rain treatments were used with each fungicide treatment. The rain treatments were no rain, and rain at 1, 30, or 60 minutes after fungicide application. There were three replicate for each combination of fungicide, rate, and rainfall interval. All fungicide formulations were diluted in water to achieve the desired spray concentrations. Fungicides were applied with a track sprayer set at 150 liters per hectare delivery volume at 2.1 atm and a speed of 1.9 km/h. A flat fan TeeJet 8003 nozzle tip was used. The nozzle tip was 50 cm above the top of the seedlings. All fungicide formulations were applied at 1/4, 1/8 and 1/16 of the recommended field rate (IX). Table 13 shows the results from these trials.
