The present invention also relates to a process for preparation of such insecticidal composition for synergistic and efficacious control of various insects-pests including entire sucking-pests complex.

[0005] BACKGROUND OF THE INVENTION

[0006] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention.

[0007] Insect pests present significant challenges to agricultural productivity, public health, and ecological balance. Developing effective insecticidal composition is essential to tackle problems. Traditional insecticide which usually rely on single active ingredient, often encounter resistance development in insect-pests populations. Additionally, the ageing process in plants can greatly affect their growth and productivity, making effective anti-ageing solutions necessary to maintain optimal plant performance.

[0008] Conventional insecticidal formulations often struggle to provide long-term control and rapid knockdown effects because target insect pest develop resistance. This resistance significantly diminishes the effectiveness of these insecticides. Moreover, traditional insecticides can harm non-target organisms and the environment, leading to issues such phytotoxicity, which causes plant discolouration and damage. As plants age, their physiological and biochemical processes change, resulting in reduced growth, decreased resistance to stress, and overall poorer health and productivity.

[0009] Many insecticidal formulations have been developed, each specifically designed based on the active ingredients and their intended uses. Agricultural insecticides are available in both pure forms and as part of agricultural formulations. These formulations usually contain one or more active ingredients along with additional excipients that enhance effects and facilitate their application.

[0010] Reference can be made to CN102210320A, which discloses insecticidal composition comprising Sulfoxaflor and pyrethroid, wherein the weight percentage ratio of the two active ingredients is (1-80): (50- 0.1), and preferably, the weight percentage ratio is (5-45): (25-0.1).

[0011] Further, reference can be made to AU2021104291 A4, which discloses as solid insecticide composition comprising: Chlorafenapyr; a surfactant; a filler; and optionally, a pH modifier.

[0012] However, current insecticidal formulations often negatively impact plants and crops, causing problems such as leaf discoloration and resistance in various stages of sucking pest like thrips, whiteflies, aphids, and jassids. Therefore, there is a need for an advanced insecticidal composition that addresses resistance, minimizes environmental harm, and support plants health to ensure sustainable and effective insect pest management. The stable synergistic insecticidal composition of the present invention provides a significant advancement in pest control. By incorporating multiple active ingredients with complementary mode of action, present stable synergistic insecticidal composition provides enhanced efficacy, improved resistance management, greater environmental safety.

[0013] The stable synergistic insecticidal composition of the present invention contributes to several advantages over traditional or conventional insecticidal formulations such as enhanced control efficacy across a broad spectrum of insect pests, effectively managing sucking pests like thrips, white fly, aphids and Jassids etc., through their complementary mode of action and knockdown effects. Additionally, the present composition promotes plant health by preventing discoloration, stimulating growth, and fortifying defences against both biological and environmental stresses. By addressing the effects of ageing on plants, the stable synergistic insecticidal composition of the present invention rejuvenates crop vitality, thereby mitigating yield losses caused by pest attack as well ageing of plants. Ultimately, the composition of the present invention supports long-term crop productivity by revitalizing plants and enhancing their resilience.

[0014] A compound of Formula I chemically known as A-[methyloxido[l-[6-(trifluoromethyl)-3-pyridinyl]ethyl]- Z'-sul ['any lidenejcyanamide belongs to sulfoximine class and is a systemic insecticide which allows it to be absorbed and translocated throughout the plant, providing protection from existing and incoming pests. It functions by targeting the nicotinic acetylcholine receptor (nAChR) in the nervous systems of insects. This mode of action disrupts neural transmission, leading to paralysis and death of insects. It is used for the control of aphids, whiteflies and certain species of thrips in various crops such as tomatoes, peppers, aubergines, cucumbers, melons, courgettes; cereals including wheat, rye, barley, oats, triticale; Cotton etc.

[0015] A compound of formula II, chemically known as 4-bromo-2-(4-chlorophenyl)-l-(ethoxymethyl)-5- (trifluoromethyl)-lH-pyrrole-3-carbonitrile is a broad-spectrum insecticide belongs to the class of arylpyrole. It has a systemic activity and has mainly stomach action but has some contact action also. It is a uncoupler of oxidative phosphorylation. It is a pro-insecticide meaning it requires bioactivation within the target insect to become active. Once gets absorbed, it metabolises into an active form that disrupts the production of adenosine triphosphate(ATP), a crucial energy molecule in cells. This disruption of ATP synthesis leads to cellular energy depletion, paralysis, and eventually death of insect. It also exhibits low volatility and low water solubility, reducing the risk of off-target movement and environmental contamination.lt is effective against numerous pests such as spider mites, caterpillars, thrips, fungus gnats, including termites, cockroaches, ants, bedbugs, flies and spiders.

[0016] Isoxazoline insecticides are utilized in agricultural practices to control a broad spectrum of insect pests. These insecticides function by targeting the gamma-aminobutyric acid (GABA) receptor and ligand-gated chloride channels in the nervous systems of insects, leading to uncontrolled neuronal activity, paralysis, and ultimately death. Isoxazolines are highly effective against a variety of pests, including fleas, ticks and certain crop damaging insects. Their mode of action is selective, with a higher affinity for insect receptors making them relatively safe for non-target species. This selective toxicity, combined with their efficacy and long-lasting activity, makes isooxazoline an important tool in pest management. Examples of isoxazoline insecticides includes isocycloseram, fluxametamide etc. are used to protect crops from insect damage contributing significantly to agricultural productivity.

[0017] For the reasons mentioned above, there exists a need to provide a stable synergistic insecticidal composition for synergistic and effective control of insect pests including sucking pests complex.

[0018] The present invention satisfies the existing needs, as well as others, and generally overcomes the deficiencies found in the prior art.

[0019] The present invention composition is synergistic, efficacious, environmentally friendly, simple to formulate, stable and is safe to use.

[0021] 4-bromo-2-(4-chlorophenyl)- 1 -(ethoxymethyl)-5-(trifluoromethyl)- lH-pyrrole-3-carbonitrile or its agrochemically acceptable salts, esters and derivatives; and C) at least one isoxazoline insecticide selected from fluxametamide and isocycloseram or its agrochemically acceptable salts, esters and derivatives for synergistic and effective control of various insects pests including entire sucking pests complex.

[0118] The terminology used, in the present disclosure, is only for the purpose of explaining a particular embodiment and such terminology shall not be considered to limit the scope of the present disclosure.

[0119] As used in the present disclosure, the forms "a,” "an," and "the" may be intended to include the plural forms as well, unless the context clearly suggests otherwise. Thus, for example, reference to a composition containing “a compound” includes a mixture of two or more compounds. It should also be noted that the term “or” is generally employed in its sense including “and / or” unless the content clearly dictates otherwise. The terms "comprises", "comprising", “including”, and “having” are open ended transitional phrases and therefore specify the presence of stated features, integers, steps, operations, elements, but do not forbid the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof. The particular order of steps disclosed in the method and process of the present disclosure is not to be construed as necessarily requiring their performance as described or illustrated. It is also to be understood that additional or alternative steps may be employed.

[0120] Variations or modifications to the composition of this invention, within the scope of the invention, may occur to those skilled in the art upon reviewing the disclosure herein. Such variations or modifications are well within the spirit of this invention.

[0121] The expression of various quantities in terms of “% w / w” or “%” means the percentage by weight, relative to the weight of the total solution or composition unless otherwise specified.

[0122] The term “active ingredient” (a.i.) or “active agent” or “active” used herein refers to that component of the composition responsible for control of various insects-pests at the same time.

[0123] The term “crop” shall include a multitude of desired crop plants or an individual crop plant growing at a locus.

[0124] The term “synergistic”, as used herein, refers to the combined action of two or more active agents blended together and administered conjointly that is greater than the sum of their individual effects.

[0125] “Bioactive amounts” as mentioned herein means that amount which, when applied for treatment of crops, is sufficient to give effect in such treatment.

[0126] The term “control” means to inhibit the ability of insect pests to survive, grow, feed and / or reproduce, or to limit the insect pests’ related damage or loss in crop plants. To “control” insect pests may or may not mean killing the insects although, it preferably means killing the insect pests.

[0127] The term “health of a plant” or “plant health” is defined as a condition of the plant and / or its products. As a result of the improved health; yield, plant vigour, quality and tolerance to abiotic or biotic stress is increased. As a result, the health of a plant is increased even in the absence of pest pressure. Accordingly, in an especially preferred embodiment according to the invention, the health of a plant is increased both in the presence and absence of biotic or abiotic stress factors. An increase in plant vigor may for example result in an increased yield and / or tolerance to abiotic or biotic stress.

[0128] One indicator for the condition of the plant is the yield. “Yield” is to be understood as any plant product of economic value that is produced by the plant such as grains, fruits, vegetables, nuts, grains, seeds, wood (e.g., in the case of silviculture plants) or even flowers (e.g. in the case of gardening plants, ornamentals).

[0229] In yet another embodiment of the present invention, the invention further provides the process for preparation of the said insecticidal composition, wherein the said composition can be one or more of Capsule suspension (CS), Dispersible concentrate (DC), Dustable powder (DP), Powder for dry seed treatment (DS), Emulsifiable concentrate (EC), Emulsifiable granule (EG), Emulsion water-in-oil (EO), Emulsifiable powder (EP), Emulsion for seed treatment (ES), Emulsion oil-in-water (EW), Flowable concentrate for seed treatment (FS), Granules (GR), Micro-emulsion (ME), Oil-dispersion (OD), Oil miscible flowable concentrate (OF), Oil miscible liquid (OL), Oil dispersible powder (OP), Suspension concentrate (SC), Suspension concentrate for direct application (SD), Suspo-emulsion (SE), Water soluble granule (SG), Soluble concentrate (SL), Spreading oil (SO), Water soluble powder (SP), Water soluble tablet (ST), Ultra-low volume (ULV) suspension, Tablet (TB), Ultra-low volume (ULV) liquid, Water dispersible granules (WG), Wettable powder (WP), Water dispersible powder for slurry seed treatment (WS), Water dispersible tablet (WT), a mixed formulation of CS and SC (ZC) or a mixed formulation of CS and SE (ZE) or a mixed formulation of CS and EW (ZW).

[0230] In further embodiment, depending on the formulation type, they comprise one or more liquid or solid carriers, appropriate surfactants (such as dispersants, protective colloids, emulsifiers, wetting agents and tackifiers), and appropriate further excipients which are customary for formulating agrochemical composition. Further excipients include e.g. organic and inorganic thickeners, bactericides, antifreeze agents, antifoams, colorants and, for seed formulations, adhesives.

[0231] In one embodiment, additives such as silwet power or silwet power super-wetter, which are based on organosilicone, serve as powder adjuvants. They enhance the water absorption efficiency of hard-to-wet soils by improving water infilteration, drainage, retention, and hydrophilicity. Tallow amine ethoxylate enhances biocompatibility in environmental applications and facilitates interactions with active ingredients. Ammonium sulphate aids in nitrogen utilization by crops and increases resistance to leaching. Epoxide soybean oil promotes enhanced uptake of active ingredients and improves composition rainfastness. These additives are characterized by stability and hygroscopic properties, ensuring efficient uptake and performance.

[0232] In one embodiment, silwet power has superspreading ability, it significantly lowers the surface tension of spray solutions, allowing them to spread uniformly across plant surfaces, including waxy or hard-to-wet leaves. This enhances the penetration and absorption of active ingredients such as insecticides, fungicides, and herbicides, leading to improved efficacy. Silwet Power is especially effective in low-volume spray applications and helps increase rain fastness and reduce runoff. Its use supports more efficient pesticide delivery, often allowing for reduced application rates.

[0233] In one embodiment, the inclusion of both Silwet Power super-wetter and tallow amine ethoxylate in a formulation significantly enhances its surface activity and delivery efficiency. Silwet Power, a trisiloxane- based super-spreader, dramatically reduces surface tension, enabling rapid and uniform spreading of the solution across plant surfaces, even on waxy or water-repellent leaves. In synergy, tallow amine ethoxylate, a non-ionic surfactant, acts as a powerful wetting and penetration agent, improving the absorption of active ingredients into plant tissues. This combination ensures maximum bioavailability and performance of agrochemical actives

[0234] In one embodiment, ammonium sulphate particularly as a water conditioner and adjuvant. It helps improve the efficacy of pesticides, by binding with hard water cations such as calcium and magnesium that would otherwise reduce pesticide absorption and activity. By preventing these ions from interacting with the active ingredient, ammonium sulphate enhances uptake into plant tissues. It may also act as a nitrogen source, supporting plant growth.

[0235] In one embodiment, Epoxidized soybean oil, a bio-based plasticizer and solvent, improves formulation compatibility, reduces phytotoxicity, and enhances the dispersion of active compounds. Derived from renewable sources, both additives support sustainable agriculture by offering low toxicity, biodegradability, and improved formulation efficiency without compromising efficacy.

[0236] In one embodiment, Silwet Power, tallow amine ethoxylate, ammonium sulphate, and epoxidized soybean oil are additives used individually or in combination to enhance the performance of agrochemical formulations. Silwet Power, a superspreading organosilicone surfactant, reduces surface tension and improves leaf coverage and penetration of active ingredients. Tallow amine ethoxylates, as non-ionic surfactants, aid in emulsification and enhance pesticide uptake. Ammonium sulphate serves as a water conditioner, preventing hard water ions from reducing pesticide efficacy, while also acting as a nitrogen source. Epoxidized soybean oil, a biodegradable solvent and plasticizer, improves formulation stability, compatibility, and reduces phytotoxicity. Used alone or synergistically, these additives optimize spray performance, improve bioavailability of actives, and support sustainable and effective crop protection.

[0237] In one embodiment, additives such as silwet power or silwet power super-wetter, tallow amine ethoxylate, ammonium sulphate, and epoxide soybean oil either alone or in combination thereof, present in the range of 0.01 - 20% by weight of the composition.

[0238] In yet another embodiment of the present invention, the present stable synergistic insecticidal composition can be applied to various crops and plants including but not limited to Chilli, Cabbage, Okra (Bhindi), Cotton, Cumin, Onion, Red-gram, Tomato, Mango, Brinjal, Rice, Paddy, Soybean, Cotton, Cruciferous vegetables, Maize, Groundnut etc.

The insect pests may be controlled by contacting the target insect pest, habitat, breeding ground or its locus with a bioactive amount of the novel and inventive composition of the present invention.

[0240] In yet another embodiment, the present stable synergistic insecticidal composition of the present invention can be applied to a plant / crop / soil by spraying, rubbing, atomizing, irrigating, evaporating, dusting, fogging, broadcasting, pouring, mist blowing, soil mixing, foaming, painting, spreading-on, drenching, dipping or drip irrigation, etc.

[0241] In yet another embodiment, the composition of the present invention can also comprise or may be applied together and / or sequentially with further active compounds. These further compounds can be selected from fertilizers or micronutrient donors or microorganisms or other preparations that influence plant growth, such as inoculants (e.g. a strain of nitrogen-fixing bacteria), and plant inducers.

[0242] Through the insecticidal composition of present invention, the number of applications to control wide range of pests appearing at the same time is minimised. The composition of present invention is highly safe to the user and to the environment. The composition offers the user a single homogenous application eliminating the need for tank mix. The composition also is cost-effective as it provides much greater simultaneous control and can be used in a variety of crops with a broader spectrum of protection.

[0276] Evaluation of synergistic effect of pesticidal composition of the present invention

[0277] A synergistic effect of two or more products exists whenever the action of an active ingredient combination is greater than the sum of the actions of the individual components. Synergism was calculated by using Colby’s method (Weeds, vol. 15 No. 1 (Jan 1967), pp. 20-2.

[0278] The synergistic action expected for a given combination of two active components can be calculated as follows:

[0279] XY

[0280] E = (X + Y) -

[0281] 100

[0282] The synergistic action expected for a given combination of three active components can be calculated as follows:

[0283] (XY+YZ+XZ) (XYZ)

[0284] E = (X + Y + Z) - + -

[0285] 100 10000

[0286] Where:

[0287] E represents expected percentage of pesticidal control for the combination of the two or three actives ingredients at defined doses (for example equal to x, y and z, respectively).

[0288] X is the percentage of pesticidal control observed by the compound (Compound of formula I) at a defined dose (equal to x).

[0289] Y is the percentage of pesticidal control observed by the compound (Compound of formula II) at a defined dose (equal to y).

[0290] Z is the percentage of pesticidal control observed by the compound (Fluxametamide) at a defined dose (equal to z).

[0291] When the percentage of pesticidal control observed for the combination is greater than the expected percentage, there is a synergism effect.

[0292] Observed control (%)

[0293] Ratio = -

[0294] Expected control (%)

[0295] Ratio of O / E > 1, synergism observed The present invention is illustrated by way of examples, the examples are meant for illustrative purposes and should not be construed as limiting.

[0296] Experiment for Synergistic activity of composition of present invention:

[0297] Example 1- Details of experiment on chilli crop: Field experiment for synergistic activity of Compound of formula 1+ Compound of formula 11+ Fluxametamide for the control of Fruit borer and yellow mite in chilli crop was conducted.

[0298] To evaluate the synergistic effect, chilli (Variety: Kashi Anmol) crop was sown in 5 m x 5 m plots maintaining 65 cm x 45 cm plant distance with three replications and in Randomized Block Design (RBD). The treatments were applied as foliar spray in the form of SC formulation @750 ml / ha. Each active component was applied twice in different ternary and binary compositions. Solo compositions were also taken for comparison. The treatment details are as under:

[0299] The treatments T1 to T28 were used as foliar application whereas no treatment was done for T29 control treatment. Two applications at 15 days interval were done of all treatments on the appearance of insects at experimental plots. Observations on pests ETL (Economic threshold level) in Chilli cropwere recorded at key intervals: before spraying, at 7 and 14 days after applications. The population of fruit borer and yellow mite was recorded from three randomly selected leave per plant and 10 plants per plot. The per cent reduction in insect population was calculated over control. Based on the per cent reduction at 14 days after spray in insects’ population the Expected control was calculated and compared with Observed control. The results of the trial have been presented here under in Table 1A. Table 1A: Synergistic effect of composition of the present invention (Compound of formula 1+ Compound of formula 11+ Fluxametamide) against Fruit borer and yellow mite in chilli crop.

[0300] It is clearly evident from the data shown in above Table 1A for per cent insect control and per cent insect pest control in chilli crop that the insecticidal composition of the present invention comprising Compound of formula 1+ Compound of formula 11+ Fluxametamide i.e., T1 to T4 are synergistic for both insect pest control with > 1 Colby’s Ratio. The binary composition (Compound of formula 1+ Compound of formula

[0301] II, Compound of formula 1+ Fluxametamide and Compound of formula 11+ Fluxametamide) T5 to T16 were less effective as no synergistic effect was observed for the control of for the control of Fruit borer and yellow mite as compared to composition of the present invention comprising Compound of formula 1+ Compound of formula 11+ Fluxametamide (T1 to T4).

[0302] Experiment for Bio-efficacy evaluation of composition of the present invention:

[0303] For the ternary and binary composition, based on Compound of formula 1+ Compound of formula 11+ Fluxametamide evaluation under field conditions, the basic test composition as Compound of formula

[0304] II I.2% + Compound of formula 1113.2% + Fluxametamide 5.2% SC were manufactured. For ternary composition, Compound of formula 111.2% + Compound of formula 1113.2% + Fluxametamide 5.2% SC was used and for binary compositions, Compound of formula II 1.2% + Compound of formula 1113.2% SC, Compound of formula 111.2% + Fluxametamide 5.2% SC and Compound of formula 1113.2% + Fluxametamide 5.2% SC were used. The solo formulations of Compound of formula 111.2% SC, Compound of formula 1113.2% SC and Fluxametamide 5.2% SC were used for comparison. The other formulations namely Compound of formula 1110 % SC and Fluxametamide 10% w / w EC available in the market were also used for comparison.

[0305] Example 2: Evaluation of the composition of the present invention on chilli

[0306] The synergistic composition of the present invention Compound of formula 111.2% + Compound of formula 1113.2% + Fluxametamide 5.2% SC was evaluated on chilli crop (Variety: Kashi Anmol). The crop sowing was done in Randomized Block Design (RBD) with three replications maintaining a distance of 60 cm x 45 cm between plants and rows.

[0307] The observations were recorded for the following objectives.

[0308] Objectives:

[0309] 1. Bio-efficacy evaluation against fruit borer on chilli crop.

[0310] 2. Bio-efficacy evaluation against yellow mite on chilli crop.

[0311] 3. Bio-efficacy evaluation based on per cent reduction in fruit borer control.

[0312] 4. Bio-efficacy evaluation based on percent reduction in yellow mite population.

[0313] 5. Bio-efficacy evaluation based on crop yield.

[0314] 6. Phytotoxicity evaluation on chilli crop.

[0315] Treatment details:

[0316] Methodology:

[0317] The treatments T1 to T17 and T19 were used as foliar application whereas no treatment was done for

[0318] T18i.e., control treatment. All treatments were applied at the time of initiation of pest in the experimental plots. Observations for fruit borer were recorded before spraying, at 7 and 14 days after the application, by observing 3 twigs on 10 random plants per plot and per cent reduction over control was calculated. Observations on yellow mite population were recorded before spraying, at 7 and 14 days after the application, application on 3 leave on 10 random plant per plot The per cent reduction in insect population 5 was also calculated over control. The crop yield was recorded at crop harvest. The observations for phytotoxicity on chilli crop at 1, 3, 7, 10 and 14 days after 1stspray were also recorded. Results are presented in Table 2A, 2B, 2C, and 2D.

[0324] Table 2D: Phytotoxicity evaluation of Compound of formula 111.2% + Compound of formula 1113.2% + Fluxametamide 5.2% SC on Chilli crop

[0325] From the examples above, it is clearly seen that the stable synergistic insecticidal composition of the present invention is superior for controlling the both insect pest at 7 & 14 days after spray (Table 2A and 2B) in chilli crop as compared to the binary and solo compositions applied at the same dosage and other products such as Compound of formula 1110 % SC and Fluxametamide 10% w / w EC available in the market. The 5 yield of chilli crop also improved in the composition of the present invention Compound of formula Ill .2% + Compound of formula 1113.2% + Fluxametamide 5.2% SC as compared to binary and solo compositions (Table 2C).

[0326] The disclosed stable synergistic insecticidal composition of the present invention Compound of formula Il 1.2% + Compound of formula 1113.2% + Fluxametamide 5.2% SC@ 562.5ml, 750ml, 937.5 ml and 1500 10 ml / ha further showed no phytotoxicity in the chilli crop even after 1, 3, 7, 10 and 14 days after spray (Table 2D).

[0327] It is evident from the above data that the composition of the present invention i.e., Compound of formula Il 1.2% + Compound of formula 1113.2% + Fluxametamide 5.2% SC resulted in good control of both insect pest in chilli with higher respective yields as compared to the reference standard products (binary 15 compositions and solo products). Further, the composition of present invention is resulted synergistic.

[0328] In particular, it has now been found, surprisingly that, for example, the insecticidal activity of the composition of present invention, compared with the insecticidal activity of individual components, is synergistic. In fact, various advantageous properties associated with the compositions according to the 20 invention, include but are not limited to: knock down effect on insect pests including sucking pests complex at all developmental stages of insects such as egg, nymph, larva, pupa, and adult, preventing discoloration of leaves of plants and crops, enhanced tenderness to plants and crops, preventing ageing of plants and crops and other advantages familiar to a person skilled in the art.

[0329] From the above investigations, it will be observed that numerous modifications and variations can be 25 effectuated without departing from the true spirit and scope of the novel concepts of the present invention.

[0330] It is to be understood that no limitations with respect to the specific embodiments illustrated is intended or should be inferred. It should be understood that all such modifications and improvements have been deleted herein for the sake of conciseness and readability but are properly within the scope of the following claims.
