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 undesired 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 earlier days manpower was utilized 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.
The non-aqueous formulation here in called as oil-based formulation i.e., OD (Oil Dispersion).
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 excipient 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 and systemic herbicides.
US9439435B2 relates to an herbicidal composition. The present invention relates to an herbicidal controlling weed in a crop by applying to weeds having an average height ranging from about 4 inches to about 8 inches a herbicidally effective amount of a composition that includes (a) fluthiacet-methyl and (b) a p-hydroxyphenylpyruvate dioxygenase (HPPD) inhibitor. The present invention relates to a formulation of herbicidal composition and a method for controlling undesired vegetation.
WO2021240489A2 relates to a synergistic herbicidal composition comprising imidazolinone herbicide, a sulfonylurea herbicide and an aryloxyphenoxy propionate herbicide. Particularly, the present invention relates to the herbicidal composition of (A) Imazethapyr or a salt or adduct thereof and (B) Chlorimuron ethyl or a salt or adduct thereof and (C) Clodinafop propargyl or a salt or adduct thereof. More particularly, the present invention relates to a formulation of herbicidal composition and a method for controlling undesired vegetation.
US20180084778A1 relates to a Synergistic herbicidal composition comprising (A) a compound of formula (I) wherein R1 is methyl, methoxy or chloro, R2 is methyl or chloro and A is a substituted heteroaryl group, or an N-oxide or salt form thereof, and (B) one or more further herbicides; as well as the use of such compositions in controlling plants or inhibiting plant growth.
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 weed control efficiency; 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 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. 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, one object of the present invention is to provide improved combinations (A) Fluthiacet methyl (B) One herbicide selected from Chlorimuron ethyl, Imazethapyr, Imazamox, Fomesafen, Lactofen, Aciflurofen, Bentazone or their salt (C) at least one more herbicide selected from Clodinafop propargyl, Cyhalofop-butyl, Diclofop, Fenoxaprop-p-ethyl, Fluazifop-p-butyl, Haloxyfop-methyl, Metamifop, Propaquizafop, Quizalofop-p-ethyl, Alloxydim, Butroxydim, Clethodim, Cloproxydim, Cycloxydim, Profoxydim, Sethoxydim, Tepraloxydim, Tralkoxydim, Penoxaden or their salt.

DETAILED DESCRIPTION OF THE INVENTION:
Formulation technology in the field of 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 extend the useful patent life of an active ingredient. It can also provide a competitive edge by improving the 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 serves 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 environmentally friendly formulation. The active ingredient is dispersed in oils or methylated crop 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) has 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 meet 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.
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 the choice of all the formulation excipients. Its dispersion and activation are key to the stability of the formulation over time.
Some important requirements 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 (A) Fluthiacet methyl (B) One herbicide selected from Chlorimuron ethyl, Imazethapyr, Imazamox, Fomesafen, Lactofen, Aciflurofen, Bentazone or their salt (C) at least one more herbicide selected from Clodinafop propargyl, Cyhalofop-butyl, Diclofop, Fenoxaprop-p-ethyl, Fluazifop-p-butyl, Haloxyfop-methyl, Metamifop, Propaquizafop, Quizalofop-p-ethyl, Alloxydim, Butroxydim, Clethodim, Cloproxydim, Cycloxydim, Profoxydim, Sethoxydim, Tepraloxydim, Tralkoxydim, Penoxaden or their salt 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.

Benefits of OD formulation containing fluthiacet methyl and herbicide(s):
• Non aqueous formulation improves penetration of spray droplets, retard evaporation loss and enhance the absorption of active ingredients into weed leaves.
• Increases spreading properties on leaf surfaces, better wetting of waxy leaf surfaces of some weeds so it accelerates the speed of kill and enhances the efficacy against tough to kill weeds.
• Improves rain fast properties which is very much essential during rainy season to ensure the efficacy of applied herbicide.
• Increases the synergistic activities between active ingredients.
• With the non-aqueous formulation, we can reduce the doses of active ingredients and thereby minimize the pesticidal load into the environment.
• Non aqueous formulations are without aromatic solvent, so it’s safe for the applicator and reduces the loading of aromatic solvent into the environment.
• Non aqueous formulation ensures better crop safety as it is without aromatic solvent.
• Due to High flash point (smoke points) of Pongamia (>220 °C), Palm oil (>240 °C), Jojoba oil (>290 °C), mahua oil (> 230 °C), vegetable oil (> 200 °C), the novel recipe of OD formulations is more stable and safer for storage at elevated temperature.
• Non aqueous formulations have thermal and chemical stability over a broad range of conditions.
• Non aqueous formulations have better pourability, so it will minimize the wastage.
• Non aqueous formulations are stable with a wider pH range.
• Non aqueous formulation reduces the toxicity hazards to the applicators, i.e., improves the safety of applicators at the time of handling and spraying the herbicides.

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. 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.
The persistence of karanj is greater than other tested botanical insecticides. The dosages at 1 and 2% of karanj oil give better control of insect pests compared with lower concentrations. Karanj oil and karanjin shows greater biological activity than other karanj extracts. The karanj oil shows good synergistic effect with a number of chemical insecticides. Therefore, karanj has great potential to be used as biopesticide because of its antifeedant; oviposition deterrent, ovicidal, roachicidal, juvenile hormone activity and insecticidal properties against a wide range of insect pests [Mukesh Kumar a & Ram Singh, Department of Entomology, Potential of Pongamia glabra Vent as an Insecticide of Plant Origin, CCS Haryana, Agricultural University, Hisar, 125 004, India, Published online: 24 Apr 2012].
Botanical pesticides are also very potent insecticides and due to their composition, they can help to fight the global problem of insects developing resistance to insecticides. Insecticides based on karanja oil shows efficiency against L. decemlineata larvae at different concentrations [ Katerina Kovarikova and Roman Pavela; United Forces of Botanical Oils: Efficacy of Neem and Karanja Oil against Colorado Potato Beetle under Laboratory Conditions; Plants 2019, 8, 608; doi:10.3390/plants8120608].
The karanja (Pongamia pinnata) seeds can be used as a potential source of oil and protein which can be used for the development of bioactive chemicals by some chemical modifications. These chemicals are biodegradable, environment friendly, and available in sufficient quantities as cheap raw material and can be effectively used for the development of eco-friendly lead molecules in pesticidal formulations for the management of fungal pathogens of agriculture as well as forests. [Neelu Singh and R. K. Verma Tropical Forest Research Institute, Jabalpur-482021, Madhya Pradesh, India]
Pongamia pinnata extract of leaves, barks, root and seeds possessed antifeedant activity and insecticides, anti-inflammatory activity, antiplasmodial properties. Simin et al., (2001)reported methanolic extracts of the seeds of Pongamia pinnata possessed antibacterial and phytotoxicity properties. Muruganandan et al., (2000) reported the extracts of Pongamia pinnata seeds were used for anti-inflammatory activity. Kurkure et al., (2001) studied Pongamia pinnata stem bark therapeutically as an antiseptic in skin diseases and for its wound healing properties. [Digamber R. More, Department of Botany, L.B.S. College, Dharmabad. Nanded. 431809 Maharashtra, India, Mirza M. Vaseem Baig; Department of Botany, Yeshwant Mahavidyalaya, Nanded. 431602 Maharashtra, India]
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.
PME (Palm-based Methyl Esters) as carrier solvents appear to enhance pesticide efficacy, which may allow for a reduction in dosage or frequency of application, help to control adverse effects and reduce the cost spent on pesticides. Therefore, PME as a carrier solvent in pesticide formulations is a promising prospect for the agrochemical industry [ Sumaiyah Megat Nabil Mohsin; Ismail Ab Raman; Zafarizal Aldrin Azizul Hasan and Zainab Idris; Palm-based Methyl Esters as Carrier Solvents in Pesticide Formulations, Technical Report, January 2018, Page no. 32-38].
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 north-western 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 monoesters 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.

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 was to study the benefits of non-aqueous (novel Oil Dispersion) composition of Fluthiacet methyl, one selected herbicide and at least one more herbicide.

EXPERIMENT-1
Example 1: Bio efficacy comparison of Novel OD (Oil dispersion) composition vs conventional formulations against mixed weed flora in Soybean crop.
Crop : Soybean (Glycine max)
Target weeds : mixed weed flora (Grasses, broad leaf, sedges)
Location : Indore, Madhya Pradesh
Number of Treatments: 9
Plot size : 6 m x 5 m=30 sq.m.
Application time :16 DAS (days after sowing), 2 to 4 leaf stage of weeds.
Application method : foliar spray with backpack sprayer attached flat fan nozzle.
Water volume : 400 litre per hectare
Observation Methods: Weed control (%): Species wise weed count recorded at 15and 30 DAA (Days after Application) by using 0.25 m2 (50 cm x 50 cm) quadrant, treatment wise in minimum 5 places randomly selected in the plot. The species wise weed count further grouped into Grasses and Broad Leaf weeds (BLW) and sedges. The data presented here as total weed control (grasses+broadleaf+sedges). The average of each variable was used together with the sum of all the variables per plot to calculate the percentage of control.

Phytotoxicity: The observations on crop safety i.e., phytotoxicity or adverse effect of treatments were recorded at regular intervals. All the visual phytotoxicity symptoms like plant yellowing, leaf scorching, tip burning, bleaching, necrosis, stunting, crinkling, epinasty, hyponasty. Three leaves from each selected plant were scored using 0-10 rating scale, whereas 0=No injury/phytotoxicity, 1=1 to 10%phytotoxicity, 2=11 to 20%, 3=21 to 30%.......10=91 to 100% phytotoxicity. Percent phytotoxicity was determined using the following formula.
