More particularly the present invention relates to a synergistic Oil Dispersion composition comprising bioactive amount of (A) Saflufenacil; (B) Pyroxasulfone; (C) At least one more herbicide selected from group of herbicides.The present invention further relates to selection of suitable formulation excipients, process of preparation of the said oil dispersion formulation and its application in the field of agriculture.

BACKGROUND OF THE INVENTION:
These days cultivation of crops and agriculture in general is cost intensive. Receiving a high yield from the cultivated crops is a key. Hence, to achieve higher yield, protecting crops from pests and diseases and weeds is vital.
Weeds are indesired or unwanted crop or plant which grows sometimes with the essential or desired crop plant and competes with the desired crop plant from an early stage in growth and development. This results in adverse effect on the growth of crop plant and yield.
In earleir days man power was utilised to remove weeds. Due to research and development in the field of an agriculture now a days chemicals are being used to kill or control the weeds.
It is desirable for the crop protection product to control the harmful plants effectively and, at the same time, to be tolerated by the useful plants in question. Thus selectivity of the crop protection product is essential to selectively kill the unwanted crops and saves the desired crop in the field.
The control of undesired vegetation is extremely important in order to achieve high crop efficiency. In many cases, herbicides have an effect against a spectrum of weeds; however, these herbicides may not be effective on certain type of other weeds, which may also be present in the crop to be protected. Therefore, there is a strong need for mixing two or more herbicides.
Hence, the most effective way to control weeds is the application of herbicide in accordance with the appropriate management practices with proper formulation thereof.
Treating plants with such a weedicide/herbicide(s) in appropriate formulation helps to control the weeds.
Various kinds of agrochemical formulations are developed based upon active ingredients and scope of application thereof. Pesticides for agriculture purpose are available both in the pure form and as well as incorporated into agrochemical formulations, which typically comprise one or more active ingredients (AIs) and additional excipients substances that enhance the effects and facilitate the application thereof, such as carriers, adjuvants or additives. These formulations can be directly applied onto the crops or, more commonly, are applied after being diluted and the spray mixture formed. The formulation type to be used is primarily defined on the basis of physicochemical characteristics of the AI(s) and can be: soluble concentrate (SL), emulsifiable concentrate (EC), emulsion in water (EW), suspension concentrate (SC), suspo-emulsion (SE), micro-emulsion (ME), oil dispersion (OD) or suspension concentrate (SC), dispersible concentrate (DC), capsule suspension (CS), dispersible granules (WG), wettable powder (WP) and others.
The various types of agrochemical formulations are the result of the existence of a large variety of AIs of different chemical natures. For example, a water soluble AI can be easily included into a water based SL while a high melting, water insoluble AI is commonly found in the form of a EC (Emulsifiable concentrate). For this reason, agrochemical formulations are distinct and can contain different inert components.
Oil dispersion (OD) formulations are non-aqueous dispersion intended for dilution into water before use, and represent the most complex of the non-aqueous suspension formulations. Oil dispersion (OD) formulations consist of a suspension of a solid technical in oil. The oil also serve as a carrier or solvent for additives. The oil dispersion is usually dispersed in water prior to spraying. Thus OD formulations are also called as adjuvanted formulation.
In recent years, OD (Oil Dispersion) formulations have been the subject of studies by companies and formulators because of their advantages with respect to the agronomic performance in the field as compared with conventional formulations. Active ingredients (AIs) formulated in different types of formulations usually exhibit different physicochemical characteristics based on type of formulation they are incorporated in. The different performance between them is due to the fact that ODs already contain in their composition oil, such as a mineral or vegetable oil, and emulsifiers, which can act as penetration adjuvants when applied in the field. Penetration adjuvants aid in the absorption of AIs by the plant and, in the case of some conventional formulations, they are used in association with the formulation in the spray mixture, ensuring agronomical effectiveness of the AI. Thus, OD formulations can be deemed “adjuvanted” formulations and do not require additional associated adjuvants to be applied in the field.
Though OD formulation is called as adjuvated formulation it still requires various adjuvants along with formulation excipients. OD formulation presents several challenges in the process of manufacturing and developing stable and effective formulation with choice of proper formulation excipient or adjuvants. To obtain a good and stable formulation over time, optimal formulation additives are required in addition to optimum processes. There were several development and research done in the filed field of formulation development of Oil Dispersion (OD) formulation. Dispersion and activation of active ingredients is the key to the stability of the formulation over time. Solvents or carrier used as a petroleum based or the aromatic solvent we replaced by the solvents in the form of vegetable oils. Vegetable oils application as a formulation excipients in OD formulation further have their own challenges for stable formulation due to stability issue associated with vegetable oil used and corresponding active ingredient. Although various research has been done in formulation development it has got many draw backs as having high dose of active ingredients and thereby maximizing the pesticidal load into the environment. Many OD formulations has less thermal and chemical stability over a broad range of conditions; increases the toxicity hazards to the applicators and thereby decreasing the safety of applicators at the time of handling and spraying the pesticides. Further some OD formulation with less suitable formulation excipients may lead to have less leaf penetration of spray droplets, and increases evaporation loss and minimize the absorption of active ingredients.
Therefore there is further need and scope in the formulation development of the OD formulation comprising one or more active ingredients with better stability profile and increases the synergistic effect of the active ingredients, reduces the toxicity with less introduction of toxic material in environment, which may reduce the dose of the pesticides and eventually produce less chemicals in environment, with better safety profile for contact herbicides.
US20210092955A1 relates to a method of controlling herbicide resistant weeds in crops. A method of controlling herbicide resistant weeds, the method comprising: Treating herbicide resistant weeds with one or more of herbicides selected from the group consisting of saflufenacil, trifludimoxazin, flumioxazin, and ethyl [3-[2-chloro-4-fluoro-5-(1-methyl-6-trifluoromethyl-2,4-dioxo-1,2,3,4-tetrahydropyrimidine-3-yl)phenoxy]-2 pyridyloxy] acetate, wherein the herbicide resistant weeds are PPO-inhibitor resistant weeds having one or more mutations selected from the group consisting of an Arg128Met mutation, an Arg128Gly mutation, an Arg128His mutation, and a Gly399Ala mutation in PPO.
WO2017129141A1 relates to a synergistic herbicidal composition. a synergistic herbicidal composition comprising pyroxasulfone, mesotrione and atrazine as the active components, wherein the weight ratio of pyroxasulfone, mesotrione and atrazine ranges from 1 to 10: 1 to 50: 1 to 100, as well as the use of the synergistic herbicidal composition of present invention for controlling the growth of undesirable plants. The present invention also provides a method of controlling the growth of undesirable plants, which comprises applying the active components pyroxasulfone, mesotrione and atrazine of the synergistic herbicidal composition of present invention to the undesirable plants or their growing locus jointly or separately. The present invention further provides a method of reducing or preventing harm caused by pyroxasulfone when applied to plants, seeds or other reproductive parts of useful crops.
WO2009112486A2 relates to an "Herbicidal compositions comprising pyroxasulfone. A herbicidally active compositions, which comprise 3-[5- (difluoromethoxy)-1 -methyl-3-(trifluoromethyl) pyrazol-4-ylmethylsulfonyl]-4, 5-dihydro- 5, 5-dimethyl-1, 2-oxazole [common name pyroxasulfone] and at least one herbicide B, which is an inhibitor of microtubule assembly. The invention furthermore relates to the use of a composition as defined herein for controlling undesirable vegetation in crops. When using the compositions of the invention for this purpose the herbicide A and the at least one herbicide B can be applied simultaneously or in succession in crops, where undesirable vegetation may occur.
Therefore there is further need to formulate the novel OD formulation which increases the synergistic activities between active ingredients by using the appropriate formulation excipients; enhance the bioefficacy, duration and spectrum of weed control; reduce the doses of active ingredients and thereby minimizing the pesticidal load into the environment; has thermal and chemical stability over a broad range of conditions; reduces the toxicity hazards to the applicators, i.e. improves the safety of applicators at the time of handling and spraying the pesticides; and improves leaf penetration of spray droplets, retard evaporation loss and enhance the absorption of active ingredients.
There is however a need for improvement of OD formulations. Many a times it has been found that single or combination of active ingredients requires a high loading dose for the better results. Further this will create a higher loading of the pesticides in the environment and toxicity to the crop plant. Further many of the OD formulation recipe is prone to lose stability when exposed to the higher temperature. In addition there are higher chances of formulation applied gets evaporated resulting in the loss of the active ingredients before penetration.
Therefore, the key objective of the present invention is to provide novel Oil Dispersion formulations (OD) with enhanced bioefficacy and which and duration of control. Further the objective of the present invention is to provide novel Oil Dispersion formulations (OD) as a non phytotoxic formulation for crop safety and for delay resistance development management with improved combinations of (A) Saflufenacil; (B) Pyroxasulfone; (C) At least one more herbicide selected from group of herbicides.

DETAILED DESCRIPTION OF THE INVENTION:
Formulation technology in the field of an agriculture is now seen as an “enabling technology” which can provide safe and effective products which are convenient to use. It can also modify the toxicity of active ingredients and improve their ability to target a specific pest. At a time when the discovery of new agrochemical compounds is more difficult and certainly a high risk and expensive operation, formulation technology can extent the useful patent life of an active ingredient. It can also provide a competitive edge by improving product quality of existing formulations, or by introducing a new formulation of an active ingredient.
OD formulations are non-aqueous dispersion intended for dilution into water before use, and represent the most complex of the non-aqueous suspension formulations. Oil dispersion (OD) formulations consist of a suspension of a solid technical in oil. The oil also serve as a carrier or solvent for additives. The oil dispersion is usually dispersed in water prior to spraying.
An Oil Dispersion is a non-aqueous suspension concentrate. It combines a very good biological efficacy with an environmental friendly formulation. The active ingredient is dispersed in oils or methylated or ethylated vegetables oils.
Oil Dispersion formulation comprises with some features as it comprises no aromatic solvent or reduced amount of aromatic solvent; is non-aqueous formulation; non-flammable and low volatility; higher efficiency.
Oil Dispersion (OD) have several advantages over standard formulations. Emulsifiable Concentrate (ECs) formulations are under a strong regulatory pressure to replace toxic and flammable solvents with a less toxic and non-flammable solutions. The novel ODs meets these needs: the oil content gives a favourable eco-toxicological profile guarantying a very high biological efficacy. Further the novel OD formulations are non-toxic and non-flammable formulations. Over the EC formulation the novel OD formulation is having very high biological efficacy and crop safety.
Suspension concentrate (SC) formulations are very safe formulations but the aqueous media is normally not ideal to boost the pesticide’s biological efficacy. As an agriculture growers standard practice, tank mix adjuvants are added to guarantee a higher performance. The novel OD, with its oil content, guarantees the best biological results. For water sensitive active ingredients, the novel OD represents the sole technical solution to liquid formulation. The novel OD formulation over SC formulation is very safe formulation along with high biological performance. Further the novel OD formulation is ideal for all the active ingredients not stable in water.
Water dispersible granules (WDG) formulations are very safe but quite expensive. Optimal biological efficacy requires adjuvants. The novel OD, with its oil content and better particle size distribution, combines high efficacy with better cost. The novel OD formulation over WDG has economic significance as having better efficacy at a lower cost.
OD formulation presents several challenges in preparation and manufacturing phase. To obtain a good and stable formulation over time, optimal formulation additives are required in addition to optimum processes. Particular attention must be given to choice of all the formulation excipients. Its dispersion and activation are key to the stability of the formulation over time.
Some important requirement of the formulation excipients are perfectly dispersible in oil, no phase separation, easy milling, with no agglomeration, excellent oil emulsification, stable dilution, good coverage and penetration, even distribution through the whole formulation, provide the right yield value of active ingredients.
Therefore an aspect of the present invention provides a synergistic agrochemical Oil Dispersion (OD) composition comprising bioactive amount of (A) Saflufenacil; (B) Pyroxasulfone; (C) At least one more herbicide selected from different group of herbicide or combination thereof;

Crops are to be understood as also including those crops which have been rendered tolerant to herbicides or classes of herbicides (e.g. ALS-, GS-, EPSPS-, PPO-, ACCase- and HPPD-inhibitors) by conventional methods of breeding or by genetic engineering. An example of a crop that has been rendered tolerant to imidazolinones, e.g. imazamox, by conventional methods of breeding is Clearfield® summer rape (canola). Examples of crops that have been rendered tolerant to herbicides by genetic engineering methods include e.g. glyphosate- and glufosinate-resistant maize varieties commercially available under the trade names RoundupReady® and LibertyLink®.

Crops are also to be understood as being those which have been rendered resistant to harmful insects by genetic engineering methods, for example Bt maize (resistant to European corn borer), Bt cotton (resistant to cotton boll weevil) and also Bt potatoes (resistant to Colorado beetle). Examples of Bt maize are the Bt 176 maize hybrids of NK® (Syngenta Seeds). The Bt toxin is a protein that is formed naturally by Bacillus thuringiensis soil bacteria. Examples of toxins, or transgenic plants able to synthesise such toxins, are described in EP-A-451 878, EP-A-374 753, WO 93/07278, WO 95/34656, WO 03/052073 and EP-A-427 529. Examples of transgenic plants comprising one or more genes that code for an insecticidal resistance and express one or more toxins are KnockOut® (maize), Yield Gard® (maize), NuCOTIN33B® (cotton), Bollgard® (cotton), NewLeaf® (potatoes), NatureGard® and Protexcta®. Plant crops or seed material thereof can be both resistant to herbicides and, at the same time, resistant to insect feeding (“stacked” transgenic events). For example, seed can have the ability to express an insecticidal Cry3 protein while at the same time being tolerant to glyphosate.

Crops are also to be understood to include those which are obtained by conventional methods of breeding or genetic engineering and contain so-called output traits (e.g. improved storage stability, higher nutritional value and improved flavour).

Other useful plants include turf grass for example in golf-courses, lawns, parks and roadsides, or grown commercially for sod, and ornamental plants such as flowers or bushes.

All the said oils used as a carrier or diluent are procured from the vendor based in Gujarat State.
Pongamia oil is derived from the seeds of the Millettia pinnata tree, which is native to tropical and temperate Asia. Millettia pinnata, also known as Pongamia pinnata or Pongamia glabra, is common throughout Asia and thus has many different names in different languages, many of which have come to be used in English to describe the seed oil derived from M. pinnata; Pongamia is often used as the generic name for the tree and is derived from the genus the tree was originally placed in. Other names for this oil include honge oil, kanuga oil, karanja oil, and pungai oil.
Pongamia oil is extracted from the seeds by expeller pressing, cold pressing, or solvent extraction. The oil is yellowish-orange to brown in colour. It has a high content of triglycerides, and its disagreeable taste and odour are due to bitter flavonoid constituents including karanjin, pongamol, tannin and karanjachromene. The physical properties of crude pongamia oil are as flash point of the pongamia oil is 225°C.
Its fruits are used in abdominal remedies. Its seeds are used in tumor treatment. Oil is used for curing rheumatism. Leaves are used against Micrococcus. Their leaves juices are used for the treatment of diarrhea cold and cough. It has curative effect for leucoderma and itches. Its oil is used as a lubricant, water paint binder. Utilization of Seed Cake as a Manure for having the proper N, P & K content and ratio. As a material for biogas (Methane) production. As a Material for Producing Proteins for Food, Pharmaceutical and Industrial Applications by Chemical and Biochemical Technologies. Production of Soluble Fibers for Food Uses.
It is medium sized tree and is found throughout India. The tree is drought resistant. Major producing countries are East Indies, Philippines, and India. The oil content varies from 27- 39%.Its cake is used as pesticide and fertilizer. The deoiled cake when applied to soil, has pesticidal value, especially against nematodes and also helps in improving soil fertility. Karanja is often planted in home steads as a shade or ornamental tree and in avenue planting along roadside and canals. It is preferred species help in controlling soil erosion and binding sand dunes due to its dense network of lateral roots.
Palm oil is an edible vegetable oil derived from the mesocarp (reddish pulp) of the fruit of the oil palms, primarily the African oil palm Elaeis guineensis, and to a lesser extent from the American oil palm Elaeis oleifera and the maripa palm Attalea maripa.
The use of palm oil in food and beauty products has attracted the concern of environmental groups; the high oil yield of the trees has encouraged wider cultivation, leading to the clearing of forests in parts of Indonesia and Malaysia to make space for oil-palm monoculture. This has resulted in significant acreage losses of the natural habitat of the three surviving species of orangutan. One species in particular, the Sumatran orangutan, has been listed as critically endangered.
Jojoba oil is the liquid produced in the seed of the Simmondsia chinensis (jojoba) plant, a shrub, which is native to southern Arizona, southern California, and northwestern Mexico. The oil makes up approximately 50% of the jojoba seed by weight. The terms "jojoba oil" and "jojoba wax" are often used interchangeably because the wax visually appears to be a mobile oil, but as a wax it is composed almost entirely (~97%) of mono-esters of long-chain fatty acids and alcohols (wax ester), accompanied by only a tiny fraction of triglyceride esters. This composition accounts for its extreme shelf-life stability and extraordinary resistance to high temperatures, compared with true vegetable oils.
The term "vegetable oil" can be narrowly defined as referring only to substances that are liquid at room temperature, or broadly defined without regard to a substance's state (liquid or solid) at a given temperature. While a large majority of the entries in this list fit the narrower of these definitions, some do not qualify as vegetable oils according to all understandings of the term.
Vegetable oils are triglycerides extracted from plants. Some of these oils have been part of human culture for millennia. Edible vegetable oils are used in food, both in cooking and as supplements. Many oils, edible and otherwise, are burned as fuel, such as in oil lamps and as a substitute for petroleum-based fuels. Some of the many other uses include wood finishing, oil painting, and skin care.
Vegetable oils, or vegetable fats, are oils extracted from seeds or from other parts of fruits. Like animal fats, vegetable fats are mixtures of triglycerides. Soybean oil, grape seed oil, and cocoa butter are examples of fats from seeds. Olive oil, palm oil, and rice bran oil are examples of fats from other parts of fruits. In common usage, vegetable oil may refer exclusively to vegetable fats which are liquid at room temperature. Vegetable oils are usually edible; non-edible oils derived mainly from petroleum are termed mineral oils.
Most, but not all vegetable oils are extracted from the fruits or seeds of plants. For instance, palm oil is extracted from palm fruits, while soybean oil is extracted from soybean seeds. Vegetable oils may also be classified by grouping oils extracted from similar plants, such as "nut oils". Although most plants contain some oil, only the oil from certain major oil crops complemented by a few dozen minor oil crops is widely used and traded.
Oils from plants are used for several different purposes. Edible vegetable oils may be used for cooking, or as food additives. Many vegetable oils, edible and otherwise, are burned as fuel, for instance as a substitute for petroleum-based fuels. Some may be also used for cosmetics, medical purposes, wood finishing, oil painting, formulation ingredient in many pharmaceutical or agricultural formulations and other industrial purposes.

Biological Examples:
The synergistic pesticide action of the inventive mixtures can be demonstrated by the experiments below. A synergistic effect exists wherever the action of a combination (ready-mix) or tank mix of active ingredient is greater than the sum of the action of each of the components alone. Therefore a synergistically effective amount or an effective amount of a synergistic composition or combination is an amount that exhibits greater pesticide activity than the sum of the pesticide activities of the individual components.
In the field of agriculture, it is often understood that the term “synergy” is as defined by Colby S.R. in an article entitled “ Calculation of the synergistic and antagonistic responses of herbicide combinations” published in the journal Weeds, 1967, 15, p.20-22, incorporated herein by reference in its entirety. The action expected for a given combination of two or three active components can be calculated as follows:

The objective of the present studies were to study the synergism between saflufenacil + pyroxasulfone+ one more herbicide selected from different groups.
Experimental study- Example 1: Weed control in maize, Zea mays.
Crops: Maize
No. of Treatments: 24
Plot size: 30 sq. mt.
Application Time: Pre emergence, i.e. 2 DAS (Days After Sowing).
Spray Volume: 375 liter water per hectare
Application Equipment: Manually operated knapsack sprayer fitted with flat fat nozzle
Weed control(%): Species wise weed count recorded by using 0.25 m2 (50 cm x 50 cm) quadrant treatment wise in minimum 5 places randomly selected in the plot. The average of each variable was used together with the sum of all the variables per plot to calculate the percentage of control.

The % weed control (observed value) data used in Colby’s formula to calculate the synergism.
Phytotoxicity: The observations on crop safety i.e. phytotoxicity or adverse effect of treatments were recorded at regular interval. All the visual phytotoxicity symptoms like plant yellowing, leaf scorching, tip burning, bleaching, necrosis, stunting, crinkling, epinasty, hyponasty recorded by rating (0 to 10 score) the entire plot in comparison with untreated control (UTC) plot. Following rating were adopted. Score 0=No injury, Score 1=1 to 10%, Score 2=11 to 20%, Score 3=21 to 30%.......Score 10=91 to 100% Phytotoxicity.
