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

[0004] BACKGROUND OF THE INVENTION

[0005] 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.

[0006] The improvement of successful insecticidal composition is critical for relieving the effects, for example, rural efficiency, general wellbeing and large environment balance. Conventional practices frequently depending on single dynamic fixings, deal with the issue of ecological effect, obstruction advancement in target bugs bothers populaces. Besides, the maturing system in plants can essentially affect their development and efficiency, requiring successful enemy of maturing answers for guarantee ideal plant execution.

[0007] The conventionally known insecticidal details battle to give long haul control and quick thump down impacts, basically because of the advancement of obstruction in target bother populaces. Insect poison obstruction has turned into a huge concern, seriously compromising the viability of customary insect sprays.

[0008] Different earlier expressions which unveil creations containing mix of insect spray actives with different insect poisons. Nonetheless, the current insecticidal blends frequently adversely affect plants and harvests like sluggish insecticidal digestion and poisonousness. Furthermore, they are incapable against preemergence and postemergence application alongside wide range in different yields. Besides, the formulations as known in the prior arts often have detrimental effects on non-target organisms and the environment, raising serious issues related to phytotoxicity, discoloration of leaves and other damages to plants. Intensifying these difficulties, the regular maturing of plant impacts different physiological and biochemical cycles, prompting diminished development, diminished protection from ecological burdens, and decreased generally wellbeing and efficiency.

[0009] Numerous insecticidal compositional have been developed, each tailored based on the active ingredients used and their intended applications. However, existing insecticidal combinations shows adverse effect on plants and crops such as discoloration of plant leaves, resistance against sucking pests complex and are ineffective against control of all stages of sucking pests complex such as thrips, white fly, aphids and Jassids etc. Further, insecticide varieties containing a single ingredient often have defects in pesticide pest control: continuous use can easily lead to drug resistance, the insecticide spectrum is narrow, and they cannot provide comprehensive protection for crops, and the cost of pesticide use for farmers is high.

[0010] Reference can be made to Chinese patent CN 114642211, which discloses a binary insecticidal compositions comprising chlorantraniliprole with Compound of formula II .

[0011] Further, reference can be made to CN102210320A, which discloses insecticidal composition composing Compound of formula I and pyrethroid, wherein the weight percentage ratio of the two active ingredients is (1 -80):(50-0.1), and preferably, die weight percentage ratio is (5-45):(25-0. 1).

[0012] However, existing prior arts disclose composition exhibiting certain limitations, including but not limited to lack of broad-spectrum activity across a wide range of crops and increased phytotoxicity.

[0013] Therefore, there remains a need for an improved insecticidal composition offering enhanced spectrum, faster insecticidal action, and suitability for both pre- and post-emergence applications with reduced crop toxicity.

[0014] The present invention thus overcome these challenges mentioned herein above. Thus, the present synergistic insecticidal compositions have an enhanced efficacy, reduce the likelihood of resistance development, reduced dosages, offers broader crop protection, improved and healthy foliage, improved crop yield, saves labour, mitigate environmental impact and economical and is yet cost effective to the end user. One promising approach involving the composition of present invention is that three actives ingredients are combined to produce a synergistic effect. The ternary insecticidal composition targets multiple biological pathways in pest, thereby increasing mortality rates and reduces the probability of resistance and where three actives in the ternary composition are mutually compatible and also resulting in stable composition also.

[0015] Thus, the aim of the present invention is to provide a stable synergistic insecticidal composition that addresses these needs by providing a novel ternary composition that combines three active ingredients and that too in specific weight percentage ranges. Composition of present invention has demonstrated superior efficacy in controlling a broad spectrum of pests while being environmentally sustainable. Furthermore, it minimizes the development of resistance amongst insect’s pests complex such as aphids, jassids, mites, white grub etc. and also for control of various insecticidal diseases at the same time. The composition of present invention also has the potential to mitigate yield losses caused by aging of the plants and pest attack and thus improves long-term crop productivity by rejuvenating plants and crops.

[0016] It has been observed by the inventors of the present invention that the composition of present invention not only enhances bio-efficacy and provides synergistic effect but also gives control of pests for a longer duration as compared to solo and binary compositions of insecticides.

[0017] A compound of Formula I chemically known as 7V-[methyloxido[l-[6-(trifluoromethyl)-3-pyridinyl]ethyl]- X4-sulfanylidene]cyanamide, is a systemic insecticide belongs to sulfoximine class. It is a Nicotinic acetylcholine receptor (nAChR) competitive modulator. It is used for the control of aphids in various crops such as tomatoes, peppers, aubergines, cucumbers, melons, courgettes; cereals including wheat, rye, barley, oats, triticale; cotton etc.

[0018] Further, a compound of Formula II chemically known as 4-bromo-2-(4-chlorophenyl)-l-(ethoxymethyl)-5- (trifluoromethyl)-lH-pyrrole-3-carbonitrile, is a pro-insecticide used to control many insects and mites including those resistant to carbamate, organophosphate and pyrethroid compounds, i.e., Spider mites; Caterpillars; Thrips; Fungus gnats; Public health applications including termites, cockroaches, ants, bedbugs, flies and spiders. It shows to have a specific mode of action on uncoupler of oxidative pho sphory 1 ation.

[0019] Moreover, diamide insecticides is a kind of pesticide that specifically targets the ryanodine receptor of Lepidopteran pests, which makes it safe, effective, targeted, and low toxicity to mammals. So, it is one of the most concerned and fastest -growing pesticide products after neonicotinoid pesticides. The diamides are the most recent addition to the limited number of insecticide classes with specific target site activity that are highly efficacious, control a wide pest spectrum, and have a favorable toxicological profile. The diamide insecticide works on the insect pest such as Cabbage loopers; Corn borers; Armyworms; Cutworms, etc.

[0020] 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.

[0021] The present invention satisfies the existing needs, as well as others, and generally overcomes the deficiencies found in the prior art.

[0022] The present invention composition is synergistic, efficacious, environmentally friendly, simple to formulate, stable and is safe to use.

[0023] Thus, a insecticidal composition of the present invention aims to overcome the problems of the prior art and provides a stable synergistic petsicidal composition comprising bioactive amounts of A) a compound of Formula I, i.e., A-[methyloxido[l-[6-(trifluoromethyl)-3-pyridinyl]ethyl]-X4-sulfanylidene]cyanamide or its agrochemically acceptable salts, esters and derivatives; B) a compound of Formula II, i.e., 4- bromo-2-(4-chlorophenyl)-l-(ethoxymethyl)-5-(trifluoromethyl)-lH-pyrrole-3-carbonitrile or its agrochemically acceptable salts, esters and derivatives; and C) at least one diamide insecticides selected from chlorantraniliprole, cyantraniliprole, cyclaniliprole, flubendiamide, tetraniliprole or its agrochemically acceptable salts, esters or its derivatives.

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.

[0118] 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.

[0119] 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.

[0120] 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.

[0121] 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.

[0122] The term “crop” shall include a multitude of desired crop plants or an individual crop plant growing at a locus. 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.

[0123] “Bioactive amounts” as mentioned herein means that amount which, when applied for treatment of crops, is sufficient to give effect in such treatment.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] 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). The plant products may in addition be further utilized and / or processed after harvesting.

[0128] In another preferred embodiment of the invention, the yield of the plants treated according to the composition and / or method of the invention, is increased synergistically.

[0129] In another especially preferred embodiment of the invention, the plant vigour of the treated plant is increased. In another preferred embodiment of the invention, the plant vigour of the plants treated according to the composition of the present invention is increased synergistically.

[0130] Another indicator for the condition of the plant is the “quality” of a plant and / or its products.

[0131] In an especially preferred embodiment of the invention, the quality of the treated plant is increased.

[0132] In another preferred embodiment of the invention, the quality of the plants treated according to the method of the invention, is increased synergistically.

[0133] The term rain fastness refers to the ability of a substance to remain effective after being applied to a surface and then exposed to rainfall or irrigation. In other words, it measures how well the substance adheres to the target surface and resists being washed away by water. A low rain fastness indicates that it may be washed off or diluted by rainfall, reducing its efficacy.

[0134] The term "Increased uptake of active ingredient" refers to the enhanced absorption or penetration of the active component of a substance into the target organism or plant. This increased uptake can lead to greater effectiveness of the product in controlling various insects-pests including sucking pests at the same time. It may occur through various mechanisms, such as improved formulation, adjuvants that enhance penetration, or modifications to the active ingredient itself to facilitate absorption. Overall, increased uptake of the active ingredient results in improved performance of the product in achieving its intended purpose.

[0135] The term “benefit: cost” refers to a ratio used in a cost-benefit analysis to summarize the overall relationship between the relative costs and benefits of a proposed composition. If a treatment has a benefit-cost ratio greater than 1.0, the treatment is expected to deliver a positive and better outcome.

[0136] In one embodiment of the present invention, the yield of the treated plant is increased.

[0137] In another embodiment of the present invention, there is synergistic and efficacious control of various insect-pests affecting the plants and crops.

[0212] In accordance with an embodiment of the present invention, there is provided a stable synergistic insecticidal composition comprising active ingredients present in the weight % range as given below:

[0213] In one embodiment of the present invention, the synergistic insecticidal composition results in an increased yield of the treated plant. In another embodiment of the invention, there is synergistic and efficacious control of various insect-pests and insecticidal diseases affecting the plants and crops. The present invention includes within its scope, all possible salts, esters and derivatives of the active ingredients of the composition.

[0214] In one of the embodiments, the synergistic insecticidal composition or formulation according to the present invention has a reduced or zero phytotoxicity with respect to important agricultural crops. This results in the present invention effective and possible in the selective control of insecticidal diseases.

[0215] In an embodiment, each individual row appearing in the table below represents the combinations in an embodiment of the present invention.

[0216] Compound of Formula I, herein pertains to A-[methyloxido[l-[6-(trifluoromethyl)-3-pyridinyl]ethyl]-X4- sulfanylidene] cyanamide or its agrochemically acceptable salts, esters and derivatives; and

[0217] Compound of formula II, herein pertains to 4-bromo-2-(4-chlorophenyl)-l-(ethoxymethyl)-5- (trifluoromethyl)-lH-pyrrole-3-carbonitrile or its agrochemically acceptable salts, esters and derivatives.

[0218] In one embodiment, additives such as silwet power or silwet power super-wetter is an organosilicone based powder adjuvant that can enhance the water absorption efficiency of hard-to-wet soils by increasing their water infiltration, drainage, water retention and hydrophilicity; tallow amine ethoxylate increases the biocompatibility in environmental applications and help in the interactions of active ingredients; ammonium sulphate help is resistant to leaching and helps the crop to utilize nitrogen efficiently; urea clathrate provides superior wetting and spray retention properties and serves as an excellent nitrogen source for crops and epoxide soybean oil provides increased active ingredient uptake and improved rain fastness to the composition; and epoxide soybean oil provides increased active ingredient uptake and improved rain fastness to the composition. The said additives are stable and hygroscopic resulting in an efficient uptake and functioning.

[0219] In one embodiment, in agrochemical compositions, additives such as urea clathrate, Silwet Power or Silwet Power Super-wetter, tallow amine ethoxylate, ammonium sulphate, and epoxide soybean oil (ESO) serve distinct yet complementary functions, both individually and synergistically. Urea clathrate stabilizes volatile active ingredients by encapsulating them, thereby improving shelf life and enabling controlled release. Silwet Power or Silwet Power Super-wetter, which are trisiloxane-based superspreaders, reduce surface tension significantly and enhance the spreading, wetting, and penetration of the formulation on plant surfaces, improving bioavailability. Tallow amine ethoxylate, a non-ionic surfactant, aids in emulsification and acts as a strong adjuvant, enhancing the uptake of systemic active ingredients. Ammonium sulphate is commonly used as a water conditioner to prevent antagonism from hard water ions like calcium and magnesium; it also enhances the absorption of certain pesticides. Epoxide soybean oil (ESO) contributes as a stabilizer and plasticizer, protecting active ingredients from UV and oxidative degradation while improving formulation compatibility.

[0220] In another embodiment, when used in combination in agrochemical composition, these additives enhance the overall efficacy, stability, and environmental safety of the agrochemical composition. For instance, the combined use of Silwet Power and ammonium sulphate can significantly boost pesticide performance, while ESO and urea clathrate together offer enhanced protection and sustained release of active ingredients. Thus, their synergistic interaction leads to improved performance and consistency under varying environmental and application conditions.

[0221] 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 insecticides, leading to improved efficacy. Silwet Power is especially effective in low-volume spray applications and helps increase rainfastness and reduce runoff. Its use supports more efficient pesticide delivery, often allowing for reduced application rates.

[0222] 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

[0223] 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. In one embodiment, Epoxide 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.

[0224] In one embodiment, Silwet Power, tallow amine ethoxylate, ammonium sulphate, and epoxide 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. Epoxide soybean oil, a biodegradable solvent and plasticizer, improves formulation stability, compatibility, and reduces phyto toxicity. Used alone or synergistically, these additives optimize spray performance, improve bioavailability of actives, and support sustainable and effective crop protection.

[0225] In one embodiment, additives such as urea clathrate, 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. In another embodiment of the present invention, the stable synergistic insecticidal composition of the present invention further comprises one or more agrochemically acceptable excipients including but not limited to the group comprising surfactant(s), dispersing agent(s), co-dispersant, anti-freezing agent(s), emulsifier(s)( (anionic and non-ionic), antifoaming agentZdefoamer(s), wetting agent(s), antimicrobial / anti -bacterial agent(s), anti-caking agent , thickening agentZthickener(s), quick coating agent(s) or sticking agentsZsticker(s), spreader(s), binder(s), pH-adjusting agent(s), anti-caking agent(s), adjuvant(s), filler(s)Zsuspension aid(s), colorant(s), carrier(s), buffering agent(s), polymer(s)rheology modifier(s), solvent(s), co-solvent(s) , biocide or a combination thereof.

[0279] 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. 20-22. The synergistic action expected for a given combination of two active components can be calculated as follows:

[0280] XY

[0281] E = (X + Y) -

[0282] 100

[0283] The synergistic action expected for a given combination of three active components can be calculated as follows:

[0284] (XY+YZ+XZ) (XYZ)

[0285] E = (X + Y + Z) - + -

[0286] 100 10000

[0287] Where:

[0288] E represents expected percentage of insecticidal control for the combination of the two or three active ingredients at defined doses (for example equal to x, y and z, respectively).

[0289] X is the percentage of insecticidal control observed by the compound (Compound of formula I) at a defined dose (equal to x).

[0290] Y is the percentage of insecticidal control observed by the compound (Compound of formula II ) at a defined dose (equal to y).

[0298] Experiment for Synergistic activity of composition of the present invention:

[0299] Example 1- Details of experiment on brinjal crop:

[0300] Field experiment for synergistic activity of Compound of formula I, Compound of formula II and Chlorantraniliprole for the control of whitefly and Shoot & Fruit borer (SFB) in brinjal crop was conducted. To evaluate the synergistic effect, brinjal (Variety: BR-112) crop was sown in 5 m x 5 m plots maintaining 75 cm x 60 cm plant distance with three replications and in Randomized Block Design (RBD). The treatments were applied as foliar spray in the form of WG 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: The treatments T1 to T28 were used as foliar application whereas no treatment was done for T29 control treatment. Two applications of all treatments were carried out at 15 -day intervals following the initial appearance of pests in the experimental plots. Observations for whitefly (Bemisia tabaci) and shoot & fruit borer Leucinodes orbonalis) infestations were recorded before spraying, and at 7 and 14 days after both the first and second applications. For whitefly, observations were taken from three leaves (top, middle and lower canopy) on each of 10 randomly selected plants per plot. The number of nymphs and adults was recorded from the underside of the leaves. For shoot and fruit borer, 10 randomly selected plants per plot were assessed. On each plant, 5 tender shoots and 10 fruits were examined. Shoots were checked for wilting, boreholes, or the presence of larvae, while fruits were examined for entry / exit holes, frass, or internal larval damage. The percentage of infested shoots and fruits was then calculated to determine the level of infestation. Based on these observations, per cent pest reduction and infestation intensity were calculated to assess the efficacy of the treatments. Based on the per cent reduction at 14 days after second spray, 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 I, Compound of formula II and Chlorantraniliprole) against insect pests in brinjal crop

[0301] It is clearly evident from the data shown in above Table 1 A for per cent insect pest control in brinjal crop that the insecticidal composition of the present invention comprising Compound of formula I + Compound of formula II + Chlorantraniliprole i.e., T1 to T4 are synergistic with > 1 Colby’s Ratio. The binary composition of two insecticides (Compound of formula I + Compound of formula II , Compound of formula I + Chlorantraniliprole and Compound of formula II + Chlorantraniliprole) T5 to T16 were less effective as synergistic effect has not been observed for the control of insect pest, as compared to insecticidal composition of the present invention Compound of formula I + Compound of formula II + Chlorantraniliprole T1 to T4. The Colby’s ratio values presented are derived from the combined efficacy against both major insect pests evaluated in this study i.e., whitefly and shoot & fruit borer. This integrated assessment highlights the broad-spectrum potential of the composition of present invention, demonstrating its superior synergistic interaction in managing both a sap-sucking pest and an internal borer simultaneously, compared to the no synergism observed in the binary compositions. Experiment for Bio-efficacy evaluation of composition of the present invention:

[0302] For the ternary and binary composition, based on Compound of formula I + Compound of formula II + Chlorantraniliprole evaluation under field conditions, the basic test composition as Compound of formula I ll .2% + Compound of formula II 13.6% + Chlorantraniliprole 5.2% WG was manufactured. The ternary composition evaluated in this study included Compound of formula I 11.2% + Compound of formula II 13.6% + Chlorantraniliprole 5.2% WG for the brinjal crop. Corresponding binary compositions assessed in brinjal included: Compound of formula I 11.2% + Compound of formula II 13.6% WG, Compound of formula 1 11.2% + Chlorantraniliprole 5.2% WG and Compound of formula II 13.6% + Chlorantraniliprole 5.2% WG. Solo formulations used for comparison included Compound of formula 1 11.2% WG, Compound of formula II 13.6% WG and Chlorantraniliprole 5.2% WG in brinjal crop. Additionally, commercially available market formulations were included for benchmarking: in brinjal Compound of formula I 21.8% w / w SC, Compound of formula II 10% SC and Chlorantraniliprole 18.50 % SC.

[0303] Example 2: Evaluation of the composition of the present invention on brinjal

[0304] The stable synergistic insecticidal composition of the present invention Compound of formula I 11.2% + Compound of formula II 13.6% + Chlorantraniliprole 5.2% WG was evaluated on brinjal crop (Variety BR 112). The crop sowing was done in Randomized Block Design (RBD) with three replications maintaining a distance of 75 cm x 60 cm. The observations were recorded for the following objectives.

[0305] Objectives:

[0306] 1. Bio-efficacy evaluation against whitefly on brinjal crop.

[0307] 2. Bio-efficacy evaluation against shoot & fruit borer on brinjal crop.

[0308] 3. Bio-efficacy evaluation based on per cent reduction in whitefly on brinjal crop.

[0309] 4. Bio-efficacy evaluation based on percent reduction in shoot & fruit borer on brinjal crop.

[0310] 5. Bio-efficacy evaluation based on crop yield.

[0311] 6. Phytotoxicity evaluation on brinjal crop.

[0312] Treatment details:

[0313] Methodology:

[0314] The treatments T1 to T18 and T20 were used as foliar application whereas no treatment was done for T19 i.e., control treatment. All treatments were applied at the economic threshold level (ETL) of the target pests in the experimental plots. In the experimental plots, observations for whitefly (Bemisia tabaci) and shoot & fruit borer Leucinodes orbonalis) were recorded before spraying and at 7 and 14 days after the first and second applications. For whitefly, data were collected from three leaves (top, middle, and lower canopy) on 10 randomly selected plants per plot. For shoot and fruit borer, 10 randomly selected plants per plot were assessed. On each plant, 5 tender shoots and 10 fruits were examined. Shoots were checked for boreholes or the presence of larvae, while fruits were examined for entry / exit holes, frass or internal larval damage. The percentage of infested shoots and fruits was then calculated to determine the level of infestation. The per cent reduction was also calculated over control. The crop yield was recorded at crop harvest. The observations for phytotoxicity on brinjal crop at 1, 3, 7, 10 and 14 days after 1stspray was also recorded. Results are presented in Table 2A, 2B, 2C and 2D.

[0321]

[0322] From the examples above, it is clearly seen that the stable synergistic insecticidal composition of the present invention is superior for controlling the whitefly (Bemisia tabaci) and shoot & fruit borer Leucinodes orbonalis) at 7 and 14 days after 1st& 2ndspray (Table 2A and 2B) in brinjal crop as compared to the binary and solo compositions applied at the same dosage and other products such as Compound of formula 121.8% w / w SC, Compound of formula II 10% SC, and Chlorantraniliprole 18.50 % SC available in the market. The yield of brinjal crop also improved in the composition of the present invention comprising Compound of formula I 11.2% + Compound of formula II 13.6% + Chlorantraniliprole 5.2% WG as compared to binary and solo compositions (Table 2C). The disclosed stable synergistic insecticidal composition of the present invention Compound of formula I 11.2% + Compound of formula II 13.6% + Chlorantraniliprole 5.2% WG @ 562.5 ml, 750 ml, 937.5 ml and 1500 ml / ha further showed no phytotoxicity in the brinjal crop even after 1, 3, 7, 10 and 14 days after 1stspray (Table 2D).
