[0001] “STABLE SYNERGISTIC PESTICIDAL COMPOSITION”

[0002] FIELD OF THE INVENTION

[0003] The present invention relates to stable synergistic pesticidal composition comprising A) a compound of Formula I, i.e., A-[methyloxido[l-[6-(trifluoromethyl)-3-pyridinyl]ethyl]-X4-sulfanyhdene]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 strobilurin fungicide selected from azoxystrobin, kresoxim-methyl, picoxystrobin, pyraclostrobin, trifloxystrobin or its agrochemically acceptable salts, esters or its derivatives for effective control of various pests including insects-pests and wide range of fungal diseases. The present invention also relates to a process for preparation of such pesticidal composition for synergistic and efficacious control of various pests including insects-pests and fungal 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] Pesticides are compounds or mixtures of substances that are mostly employed in public health programmes or agriculture in order to protect plants from pests, weeds or diseases. Typical pesticides include insecticides, fungicides, herbicides, rodenticides, and plant growth regulators. Combination of different pesticides with diverse mode of action for broad spectrum insect control is known in the art. However, repeated use of insecticides often leads to resistance development. Insecticide resistance is a heritable change in pest populations that are susceptible to a particular insecticide, or group of insecticides. In practice, insecticide resistant insects are insects that cannot be repeatedly and properly controlled by the registered rate of an insecticide. Pest populations may not be affected by multiple applications of insecticide at normal rate if the insecticide resistance level is high.

[0007] Combination of insecticides and fungicides are used to broaden the spectrum of control of insects and fungal pests, reduce dosages, thereby reducing their environmental impact, and reducing the likelihood of development of resistance. The combination of insecticides and fungicides improves the control of insects and fungal disease. Treating crops with combination of insecticides and fungicides helps reduce the damage caused by soil pests. Another advantage of treating crops or certain plant propagation materials is that higher yields can be obtained by improving germination rates, increasing the plant stand count, improved plant health. Fungal infection and insect infestation can happen at the same time in many commercially valuable crops, including rice, peppers, grapes, and other agricultural products.

[0008] Various prior arts which disclose compositions comprising combination of insecticide actives with other insecticides or fungicides are known. However, the existing pesticidal combinations often have negative impact on plants and crops such as slow pesticidal metabolism and toxicity. Additionally, they are ineffective against preemergence and postemergence application along with broad spectrum in various crops.

[0009] Reference can be made to CN114467949 A, which discloses the composition comprises effective active ingredients, wherein the effective active ingredients comprise a compound I and a compound II, the compound I is 7-chloro-l-cyclopropyl-6-fluoro-4-oxo-l, 4-dihydroquinoline-3-carboxylic acid-2- methoxyethyl ester, and the compound II is one of a bactericide and an insecticide.

[0010] Further 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, existing pesticidal composition also show antagonistic impact on plants and harvests, for example, staining of plant leaves, resistance against different pests including bug pets and contagious infections and are inadequate against control of all phases of bugs bothers and furthermore for control of different parasitic sicknesses simultaneously.

[0013] The present invention thus overcome these challenges mentioned herein above. Thus, the present stable synergistic pesticidal 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 stable synergistic pesticidal composition targets multiple biological pathways in pest, thereby increasing mortality rates and reduces the probability of resistance and where three actives in the composition are mutually compatible and also resulting in stable composition also.

[0014] Thus, the aim of the present invention is to provide a stable synergistic pesticidal composition that addresses these needs by providing a novel pesticidal 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 fungal 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.

[0015] 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 and fungicides.

[0016] 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.

[0017] 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 heakth 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.

[0018] Moreover, strobilurin fungicides are now more properly referred to as Qol fungicides. Qol fungicides are excellent as preventive fungicides, because they all effectively kill germinating spores. All Qol fungicides share a common biochemical mode of action: they all interfere with energy production in the fungal cell. They block electron transfer at the site of quinol oxidation (the Qo site) in the cytochrome bcl complex, thus preventing ATP formation. These fungicides control an unusually wide array of fungal diseases, including diseases caused by water molds, downy mildews, powdery mildews, leaf spotting and blighting fungi, fruit rotters, and rusts. They are used on a wide variety of crops, including cereals, field crops, fruits, tree nuts, vegetables, turfgrasses, and ornamentals.

[0019] 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.

[0020] The present invention satisfies the existing needs, as well as others, and generally overcomes the deficiencies found in the prior art.

[0021] The present invention composition is synergistic, efficacious, environmentally friendly, simple to formulate, stable and is safe to use.

[0022] Thus, a pesticidal 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-sulfanyhdene]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 strobilurin fungicide selected from azoxystrobin, kresoxim-methyl, picoxystrobin, pyraclostrobin, trifloxystrobin or its agrochemically acceptable salts, esters or its derivatives.

[0094] DETAILED DESCRIPTION OF THE INVENTION In describing the embodiments of the invention, specific terminology is resorted for sake of clarity. However, it is not intended that the invention be limited to specific terms so selected and it is to be understood that each specific term includes all technical equivalents that operate in a similar manner to accomplish a similar purpose.

[0095] Discussed below are some representative embodiments of the present invention. The invention in its broader aspects is not limited to the specific details and representative methods.

[0096] All technical and scientific terms used herein have the same meanings as commonly understood by someone ordinarily skilled in the art to which the present subject matter belongs.

[0097] 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.

[0098] 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.

[0099] 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.

[0100] 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.

[0101] 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.

[0102] 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 and fungal diseases at the same time. The term “crop” shall include a multitude of desired crop plants or an individual crop plant growing at a locus.

[0103] 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.

[0104] “Bioactive amounts” as mentioned herein means that amount which, when applied for treatment of crops, is sufficient to give effect in such treatment.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] In another preferred embodiment of the invention, the yield of the plants treated according to the method of the invention, is increased synergistically.

[0110] 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.

[0111] Another indicator for the condition of the plant is the “quality” of a plant and / or its products.

[0112] In an especially preferred embodiment of the invention, the quality of the treated plant is increased. In another preferred embodiment of the invention, the quality of the plants treated according to the method of the invention, is increased synergistically.

[0113] 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.

[0114] 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 and wide range of fungal diseases 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.

[0115] 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.

[0116] In one embodiment of the present invention, the yield of the treated plant is increased.

[0117] In another embodiment of the present invention, there is synergistic and efficacious control of various insect-pests and fungal diseases affecting the plants and crops.

[0118] Another embodiment of the present invention, includes within its scope, all possible salts, esters and derivatives of the active ingredients of the composition.

[0119] It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments of the invention only and is not intended to limit the scope of the invention in any manner.

This results in the present invention effective and possible in the selective control of fungal diseases. In an embodiment, each individual row appearing in the table below represents the combinations in an embodiment of the present invention.

[0176] 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

[0177] 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.

[0178] 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.

[0179] 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 fungicides and insecticides. Epoxide soybean oil (ESO) contributes as a stabilizer and plasticizer, protecting active ingredients from UV and oxidative degradation while improving formulation compatibility.

[0180] 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.

[0247] Evaluation of synergistic effect of pesticidal composition of the present invention 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.

[0248] The synergistic action expected for a given combination of two active components can be calculated as follows:

[0249] XY

[0250] E = (X + Y) -

[0251] 100

[0252] The synergistic action expected for a given combination of three active components can be calculated as follows:

[0253] (XY+YZ+XZ) (XYZ)

[0254] E = (X + Y + Z) - + -

[0255] 100 10000

[0256] Where:

[0257] 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).

[0258] X is the percentage of pesticidal control observed by the compound (Compound of formula I ) at a defined dose (equal to x).

[0259] Y is the percentage of pesticidal control observed by the compound (Compound of formula II) at a defined dose (equal to y).

[0260] Z is the percentage of pesticidal control observed by the compound (Pyraclostrobin) at a defined dose (equal to z).

[0261] When the percentage of pesticidal control observed for the combination is greater than the expected percentage, there is a synergism effect.

[0262] Observed control (%)

[0263] Ratio = -

[0264] Expected control (%)

[0265] Ratio of O / E > 1, synergism observed

[0266] The present invention is illustrated by way of examples, the examples are meant for illustrative purposes and should not be construed as limiting.

[0267] Experiment for Synergistic activity of composition of the present invention:

[0268] Example 1- Details of experiment on rice crop: Field experiment for synergistic activity of Compound of formula I + Compound of formula II + Pyraclostrobin for the control of rice blast, brown plant hopper (BPH) and yellow stem borer in rice crop was conducted.

[0269] To evaluate the synergistic effect, rice (Variety: Pusa Basmati 1121) crop was sown in 5 m x 5 m plots maintaining 20 cm x 20 cm plant distance with three replications and in Randomized Block Design (RBD).

[0270] The treatments were applied as foliar spray in the form of WG formulation @500 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:

[0271] 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 insect and disease at experimental plots. Observations for blast disease (causal organism: Magnaporthe grisea) were recorded before spraying, at 7 and 14 days after the first and second applications, by observing 3 leaves on 10 random plants per plot and per cent disease incidence was calculated. Per cent disease incidence was calculated accordingly. Similarly, observations on BPH Nilaparvata lugens) population were recorded before spraying, at 7 and 14 days after the first and second applications, application on 10 random hills per plot. Yellow stem borer (Scirpophaga incertulas') population in paddy was recorded by counting dead hearts (vegetative stage) / white ears (reproductive stage) from 10 random hills. The per cent reduction in disease incidence and insect population was calculated over control. Based on the per cent reduction at 14 days after second spray in disease incidence and insect population the Expected control was calculated and compared with Observed control. The results of the trial have been presented here under in Table 1 A.

[0272] Table 1A: Synergistic effect of composition of the present invention (Compound of formula I + Compound of formula II + Pyraclostrobin) against insect and blast disease in rice crop

[0273] It is clearly evident from the data shown in above Table 1 A for per cent disease control and per cent insect pest control in rice crop that the pesticidal composition of the present invention comprising Compound of formula I + Compound of formula II + Pyraclostrobin i.e., T1 to T4 is synergistic for both disease and insect pest control with > 1 Colby’s Ratio. The binary composition comprising (Compound of formula I +

[0274] Compound of formula II, Compound of formula I + Pyraclostrobin and Compound of formula II + Pyraclostrobin) T5 to T16 are less effective as no synergistic effect was observed for the control of BPH and yellow stem borer, as compared to stable synergistic pesticidal composition of the present invention comprising Compound of formula I + Compound of formula II + Pyraclostrobin (T1 to T4). Experiment for Bio-efficacy evaluation of composition product of the present invention:

[0275] For the ternary and binary compositions, based on Compound of formula I + Compound of formula II + Pyraclostrobin evaluation under field conditions, the basic test composition as Compound of formula I 17.4% + Compound of formula II 19.2% + Pyraclostrobin 22.4%WG were manufactured. For ternary composition, Compound of formula I 17.4% + Compound of formula II 19.2% + Pyraclostrobin 22.4%WG was used and for binary compositions, Compound of formula I 17.4% + Compound of formula II 19.2% WG, Compound of formula I 17.4% + Pyraclostrobin 22.4%WG and Compound of formula II 19.2% + Pyraclostrobin 22.4%WG were used. The solo formulations of Compound of formula I 17.4%, Compound of formula II 19.2% and Pyraclostrobin 22.4%WG were used for comparison. The other formulations namely Compound of formula I 21.8 % w / w SC, Compound of formula II 10 % SC and Pyraclostrobin 100g / l CS available in the market were also used for comparison.

[0288] Treatment details:

[0289] Methodology:

[0290] 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 time of initiation of pest in the experimental plots. Observations for blast disease (causal organism: Magnaporthe grisea) were recorded before spraying, at 7 and 14 days after the first and second applications, by observing 3 leaves on 10 random plants per plot and per cent disease incidence was calculated. Similarly, observations on BPH Nilaparvata lugens) population were recorded before spraying, at 7 and 14 days after the first and second applications, application on 10 random hills per plot. Yellow stem borer population in paddy was recorded by counting dead hearts (vegetative stage) / white ears (reproductive stage) from 10 random hills per plot. The percent reduction in disease incidence and insect population was also calculated over control. The crop yield was recorded at crop harvest. The observations for phytotoxicity on rice crop at 1, 3, 7, 10 and 14 days after 1stspray were

[0291] 5 also recorded. Results are presented in Table 2 A, 2B, 2C, 2D and 2E.

[0306]

[0307] From the examples above, it is clearly seen that the stable synergistic pesticidal composition of the present invention is superior for controlling the blast disease (causal organism: Magnaporthe grisea) at 7 and 14 days after 1st& 2ndspray (Table 2 A) and for controlling BPH (Nilaparvata lugens) population and Yellow stem borer (Scirpophaga incertulas) at 7 & 14 days after 1st& 2ndspray (Table 2B and 2C) in rice crop as compared to the binary and solo composition applied at same dosage and other products such as Compound of formula I 21.8 % w / w SC, Compound of formula II 10 % SC and Pyraclostrobin 100g / l CS available in the market. The yield of rice crop also improved in the composition of the present invention comprising Compound of formula I 17.4% + Compound of formula II 19.2% + Pyraclostrobin 22.4%WG as compared to binary and solo compositions (Table 2D). The stable synergistic pesticidal composition of the present invention Compound of formula I 17.4% + Compound of formula II 19.2% + Pyraclostrobin 22.4%WG @ 375ml, 500 ml, 625ml and 1000 ml / ha further showed no phytotoxicity in the rice crop even after 1, 3, 7, 10 and 14 days after 1stspray (Table 2E).

[0308] It is evident from the above data that the composition of the present invention i.e., Compound of formula I 17.4% + Compound of formula II 19.2% + Pyraclostrobin 22.4%WG resulted in good control of blast disease, BPH and yellow stem borer in rice with higher respective yields as compared to the reference standard products (binary compositions and solo products). Further, the composition of present invention is resulted synergistic. In particular, it has now been found, surprisingly that, for example, the pesticidal activity of the composition of present invention, compared with the pesticidal activity of individual components, is synergistic. In fact, various advantageous properties associated with the compositions according to the 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.
