The following specification describes the invention and discloses a environmentally safe stable oil based fungicidal combination comprising (a) methyl (2E)-2-{2-[6-(2-cyanophenoxy) pyrimidin-4-yloxy]phenyl}-3-methoxyacrylate and (b) manganese ethylenebis (dithiocarbamate) (polymeric) complex with zinc salt which are at weight ratio of 0.1:20-10: 1 molar ratio of first active ingredient to the second active ingredient, more preferably in the ratio of 1.14 : 10.0. More particularly, the invention relates to oil- based suspension formulations comprising an agriculturally active solid having improved storage stability and enhanced performance in term of uptake, spreading, rainfastness and curativity. The fungicidal combination can be prepared to oil suspension (OS), also referred to as oil dispersion (OD) formulation as per the abbreviation and terminology used. The active compound combinations according to the invention have very good fungicidal properties and can be employed for controlling phytopathogenic fungi, such as Plasmodiophoromycetes, Oomycetes, Chytridiomycetes, Zygomycetes, Ascomycetes, Basidiomycetes Deuteromycetes, etc, which causes the disease in field and green house crops like cereals, pulses, oilseeds, vegetables, fruits, spices and ornamental crops. The composition of the present invention could be applied to plants, seeds, fruits, soil as preventive and curative state
Background of the Invention:
Despite negative perception of the public, fungicides are still going to be used for many years to ensure food supply and safety for the ever growing world population. It is clear that, although pesticides remain indispensable in agriculture, a great potential still exists to improve their efficiency and thus reduce their input into the environmental and food chain. In general, fungicidal active substances are not employed in their pure form, but in the form of a formulation. Depending on the field of application, and the mode of application, and depending on physical, chemical and biological parameters, the active substances are employed as active substance formulation in the form of a mixture with customary carriers, adjuvants and additives. The combinations with fungicidal active substances for widening the spectrum of action and/or for protecting the crop plants are also known. Though, the ability of these combination compounds to efficiently control diseases varies with a large number of the parameters including, but not limited, the type of the formulations of combination fungicide, the type of phytopathogenic fungi to be controlled, the type of the plant to be protected and ambient conditions, such as temperature, precipitations, humidity, length of the day, biological diversity of the micro environment, the like. Therefore, formulations of fungicidal active substances in combinations should generally have good chemical and physical stability, good application properties, user friendliness, having good biological activity and enhanced efficacy combined with high selectivity. Proper formulation and efficient delivery systems of combinations fungicides are the key elements in the performance of different products. Recently, the use of vegetable oils (seed oils) and mineral oil has been increased since they are more biodegradable and originate from renewable resources. These oils are very useful in pesticide formulations as the both oil as well as active materials are expected to contribute to the biological activity (Wang and Liu, 2007).
Methyl (2E)-2-{2-[6-(2-cyanophenoxy) pyrimidin-4-yloxy]phenyl}-3-methoxyacrylate is a strobilurin fungicide active substance with protective and curative action, which are effective against a number of diseases caused by Oomycetes sp. Ascomycetes sp., Basidiomycetes sp. and Deuteromycetes sp. Is commercially available (see, for example, "The Pesticide Manual" 14th edition pages 54 to 56). It is commercially available in SC and WDG formulations either in singly or in combinations with various other fungicidal active ingredients to control various kind of disease on different agricultural crops. Oil suspension and oil dispersion formulations of Methyl (2E)-2-{2-[6-(2-cyanophenoxy) pyrimidin-4-yloxy]phenyl}-3-methoxyacrylate and its combinations with other fungicidal active ingredient are not known so for Manganese ethylenebis (dithiocarbamate) (polymeric) complex with zinc salt is a dithiocarbamate fungicides salts with protective action which is widely used in grape, potato, tomato sugar beet, cabbage, kale, celery, peppers, beans, beans, eggplant, melons, cotton, peanuts, wheat, corn, rice, tea, rubber, citrus, mango, banana, litchi, pear, peach, rose, rose, tobacco and so on to control fungal disease caused by Oomycetes sp. Ascomycetes sp., Basidiomycetes sp. and Deuteromycetes sp . It is commercially available (see, for example, "The Pesticide Manual" 14th edition (2006), The British Crop Protection Council, pages 646-649). Combinations of manganese ethylenebis (dithiocarbamate) (polymeric) complex with zinc salt with other fungicidal active substance, specially strobilurins, in oil suspension (OS) or Oil dispersion (OD) formulation are not known so far.
Most of the formulations of Methyl (2E)-2-{2-[6-(2-cyanophenoxy) pyrimidin-4-yloxy]phenyl}-3-methoxyacrylate and Manganese ethylenebis (dithiocarbamate) (polymeric) complex with zinc salt, either in individual or in combinations, are generally designed based on customer needs and physic-chemical properties of the active ingredients but formulations of these fungicidal active ingredient, particularly in combinations, with good application properties, environment and user friendliness, having good biological activity and enhanced efficacy combined with high selectivity are overlooked.
There are two major categories of formulations of Methyl (2E)-2-{2-[6-(2-cyanophenoxy) pyrimidin-4-yloxy]phenyl}-3-methoxyacrylate and Manganese ethylenebis (dithiocarbamate) (polymeric) complex with zinc salt are available in market.
Firstly formulations using petroleum based solvent or water based include emulsifable concentrates (EC), suspension concentrates (SC), soluble liquids (SL), etc. which are either unsafe to the environment or not give the proper efficacy against target diseases due to lack of adhesion to the plant surface, particularly when the spray droplet hits the leaf for the first time as it tend to bounce back when they strike the plant surface hence loses of the active ingredient. Further these types of the formulations are tends to wash off or run off from the plant surface after application resulted into poor and short duration disease control.
Secondly, solid formulations like WP and WG/WDG, especially for Manganese ethylenebis (dithiocarbamate) (polymeric) complex with zinc salt and it’s combinations are based on either bentonite silica, diatomaceous earth and talk powder which are either not environmental and user friendly or tends to deposits on plant surface in form of powder which directly or indirectly inhibits photosynthetic activity in plant and effects on marketable quality of the fruits due to deposit of powdery stain on fruit.
Thirdly, most of the plant disease specially late blight of Potato caused by Phytophthora spp and downy mildew of grape caused by Parenospora spp. are tends to occurs and progress faster under higher humidity in environment and retention of water on leaf surface during frequent precipitation which is also a pre-disposing factor for occurrence and severity of the diseases.In such condition, application of traditional formulation of fungicides like emulsifable concentrates (EC), suspension concentrates (SC), soluble liquids (SL), WP and WDG are tend to wash off or run off from the plant surface after application resulted into poor and short duration disease control.
Formulations comprising an agriculturally active solid suspended in plant oil and mineral oil, as the primary component of the continuous phase, have been found advantageous in the treatment of agricultural substrates. Examples of such formulations have been designated by CropLife International as OD ("oil dispersion") and OF ("oil-miscible flowable concentrate") formulations. Such formulations provide certain advantages to the end user. They allow the formulation of active ingredients in solid suspended form, which ingredients some time cannot be formulated in water because of hydrolytic instability. Also, such formulations allow oil-based adjuvants to be incorporated into the formulation to enhance efficacy. Further, in many cases active ingredients have a solubility limit on the amount that can be loaded into a formulation, such as an EC and SC formulations, and so suspension in an oil-based system can possibly load to higher active ingredient strength formulations than would otherwise be possible. Formulation based on oil also enhanced the performance of active ingredient in combinations in term of uptake, spreading on plant surface, rainfastness and curativity.
Unfortunately, a major limitation on an oil-based agricultural formulation, such as an OD and OS formulation, is the need to physically stabilize the formulation for potentially long periods of storage especially for two active ingredients in combinations which are having different chemical and physical properties, so that it can be in a consistently useable form for later end use. Further, difficulty has been experienced in stabilizing certain ingredients at their most desirable concentrations.
There is a need in the art to provide environmentally safer and stable fungicidal compositions having two active ingredients with different physical and chemical properties with two primary goals in the mind: (1) providing an environmentally safe, easy and effective combination formulation of two fungicidal active with enhanced efficacy and less impact on photosynthetic activities on plant upon dilution in a carrier such as Water or oil, and spray application to an area to be treated (2) maintaining the stability of the product during storage.
It was surprisingly and unexpectedly found by the present inventors that a selective combination of two fungicidal active ingredient comprising (a) Methyl (2E)-2-{2-[6-(2-cyanophenoxy) pyrimidin-4-yloxy]phenyl}-3-methoxyacrylate and (b) Manganese ethylenebis (dithiocarbamate) (polymeric) complex with zinc salt formulated in oil suspension or oil dispersion formulation is possesses enhanced efficacy, improved penetration and long duration control of phytopathogenic fungi as compared to its other traditional formulations with long storage stability across a wide temperature range and having no adverse impact on photosynthetic activity in plant and fruit quality because no stain on marketable fruits as compared with WP and WDG formulation. The economic factor should of course not be overlooked in the search for novel fungicidal compounds

The fungicidal compositions according to the present invention possess advantageous curative, preventive and antisporulant fungicidal activity to protect plants, fruit and seeds. The present combination can be used to protect plants or parts of plants, e.g. fruit, blossoms, flowers, foliage, stems, roots, cuttings, tubers of plants or culture plants infected, harmed or destroyed by micro-organisms, whereby later-growing parts of plants are protected against such micro-organisms. Application may be made by ground or aerial spray equipment.
As examples of the wide variety of culture plants in which the combinations of present invention can be used, there may be named for example cereals, e.g. wheat, barley, rye, oats, rice, sorghum and the like; beets, e.g. sugar beet and fodder beet; pome and stone fruit and berries, e.g. apples, pears, plums, peaches, almonds, cherries, strawberries, raspberries and blackberries; leguminous plants, e.g. beans, lentils, peas, soy beans; oleaginous plants, e.g. rape, mustard, poppy, olive, sunflower, coconut, castor-oil plant, cocoa, ground-nuts; cucurbitaceae, e.g. pumpkins, gherkins, melons, cucumbers, squashes; fibrous plants, e.g. cotton, flax, hemp, jute; citrus fruit, e.g. orange, lemon, grapefruit, mandarin; vegetables, e.g. spinach, lettuce, asparagus, brassicaceae such as cabbages and turnips, carrots, onions, tomatoes, potatoes, hot and sweet peppers; laurel-like plants, e.g. avocado, cinnamon, camphor tree; or plants such as maize, tobacco, nuts, coffee, sugar-cane, tea, vines, hops, bananas, rubber plants, as well as ornamental plants, e.g. flowers, shrubs, deciduous trees and evergreen trees such as conifers. This enumeration of culture plants is given with the purpose of illustrating the invention and not to delimiting it thereto.
A particular mode of administering an antifungal composition of the present invention, is the administration to the aboveground parts of plants, in particular to the leaves thereof (leaf-application). The number of applications and the administered doses are chosen in accordance with the biological and climatic conditions of life of the causative agent. The antifungal compositions though, can also be applied to the soil and get into the plants through the root system (systemic activity), in case the locus of the plants is sprayed with a liquid composition or if the components are added to the soil in a solid formulation e.g. in the form of a granulate (soil application).
The fungicidal compositions of the present invention can also be used for protecting seed against fungi. To that effect the present fungicidal compositions can be coated on seed, in which case the seed grains are drenched consecutively with a liquid composition of the active ingredients or if they are coated with a previously combined composition. The compositions can also be sprayed or atomized onto the seed.
When using the active compound combinations according to the invention, the application rate can be varied within a relatively wide range, depending on the kind of application. For the treatment of parts of plants, the active-compound combination application rates are generaly between 0.1 and 10 000 g/ha, preferably between 100 and 2500 g/ha. For seed dressing, the active compound combination application rates are generally between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 20 g per kilogram of seed. For the treatment of the soil, the active-compound combination application rates are generally between 0.1 and 10 000 g ha preferably between 1 and 5 000 g/ha.
The good fungicidal activity of the oil dispersion or oil suspension formulation of two active-compound combinations according to the invention demonstrated by the examples below. Whereas the WG, WDG and SC formulations exhibit weaknesses in fungicidal activity.
To test for protective activity, young plants are sprayed with the active compound preparatior at the stated application rate. After the spray coating has dried on, the plants are inoculatec with an aqueous spore suspension of Phytophthora infestans. The plants are then placed in ai incubation cabin at about 20°C and 100% relative atmospheric humidity. Evaluation is carried out 3 days after inoculation. Here, 0% means an efficacy which corresponds t; that of the control, whereas an efficacy of 100% means that no infection is observed. The table below shows clearly that the activity found for the active compound combination formulated in oil suspension or oil dispersion according to the present invention is greater than the WG. WP and SC formulations i.e. an enhanced effect is present. The enhanced effect found is surprisingly clearly pronounced for the formulations of two fungicidal active ingredients in oil dispersion or oil suspension, according to the invention, which has, on application of plant surface, good adhesion, no bounce back of droplet, good penetrations and good surface area coverage.
Although the invention has been described above with reference to the disclosed embodiments, those skilled in the art will readily appreciate that the specific embodiments detailed are only illustrative of the invention. It should be understood that various modifications can be made without departing from the spirit of the invention. Accordingly, the invention is limited only by the following claims.
