Description

[0001] STABLE SYNERGISTIC PESTICIDAL COMPOSITION AND PROCESS THEREOF FIELD OF THE INVENTION

[0002] The present invention relates to a pesticidal composition in the field of agrochemical compositions. Particularly, the present invention relates to a stable synergistic pesticidal composition comprising A) Trifloxystrobin or its isomers, agrochemically acceptable salts, esters and derivatives; B) a compound of Formula I, i.e., 2,4,5,6-tetrachloro-1,3-benzenedicarbonitrile or itsagrochemically acceptable salts, esters and derivatives; and C) Imidacloprid or its isomers, agrochemically acceptable salts, esters or its derivatives for effective control of various pests including insects-pests, fungal pathogens, etc. and wide range of diseases caused by various pests such as insects-pests, fungal pathogens, etc. The present invention also relates to a process for preparation of such pesticidal composition for synergistic and efficacious control of various pests including but not limited to insects-pests and fungal pathogens and diseases associated with such pests.

[0003] BACKGROUND OF THE INVENTION

[0004] To accomplish an effective safe and sustainable pesticidal management simultaneous infestation of the insect-pests and fungal pathogens are a persistent problem to overcome. Modern crop protection strategies therefore increasingly rely upon pesticidal compositions capable of providing broad-spectrum protection against multiple biological stress factors while maintaining crop safety and environmental compatibility.

[0005] Conventional crop protection practices typically involve repeated application of individual insecticides and fungicides. However, prolonged and indiscriminate use of single-active pesticidal products has resulted in several challenges including development of resistance in target pest populations, resurgence of sucking pests, reduced field efficacy, phytotoxic effects, and adverse environmental impact. In particular, resistance development in sucking pest complexes such as aphids, whiteflies and thrips has reduced the effectiveness of many existing pesticidal compositions.

[0006] Similarly, fungal pathogens affecting cereals, fruits and vegetable crops have shown increasing tolerance to single-site fungicides, thereby reducing their long-term effectiveness. Whilefungicides belonging to the Strobilurin class provide broad spectrum disease control, reliance on single mode-of-action products may accelerate resistance development and limit residual protection.

[0007] References can be made to CN 106614714, which discloses insecticidal composition for planting the onions is characterized by comprising the following components in parts by weight: 15-20 g of deltamethrin, 20-30 g of leston 48% missible oil, 12-15 g of imidacloprid, 10-11 g of Compound of Formula I, 5-8 g of prohydantoin and 1000 g of water.

[0008] Further, CN103918703 discloses water dispersible granules of imidacloprid in a weight ratio of 30:1 to 10:1.

[0009] State of art in pesticidal composition are tailored based on the active ingredients are used along with their intended applications, and attempts have been made to employ tank mixtures or premix combinations of pesticidal active ingredients to improve pest and disease management. However, existing pesticidal 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 etc, and failed to provide a simultaneous control of insect-pest and fungal pathogens.

[0010] Thus, there is a need to overcome these challenges mentioned herein above. In view of the same, the present invention aims to develop a stable synergistic pesticidal composition providing simultaneous management of insect-pests and fungal pathogens and their associated diseases through multiple modes of action while maintaining crop safety, improving efficacy, and potentially reducing the likelihood of resistance development. It also ensures broader crop protection, improved and healthy foliage, improved crop yield, reduced labour, minimum environmental impact and yet cost effective to the end user.

[0011] In view of these challenges, the present invention provides an integrated pesticidal composition comprising active ingredients having complementary biological activity and distinct modes of action. Trifloxystrobin, a Qol fungicide with systemic and translaminar properties, was considered effective for curative and preventive management of several foliar fungal diseases. Additionally,Trifloxystrobin is reported to exhibit a physiological “greening effect” in plants by enhancing chlorophyll retention and delaying senescence, thereby maintaining greener and healthier foliage for a longer duration. This effect is associated with improved photosynthetic efficiency and stress tolerance, which may contribute to better overall plant vigor and crop performance under disease or environmental stress conditions. Compound of Formula II, a multi-site contact fungicide provides protective surface activity and contributing toward resistance management through its non-specific mode of action. Imidacloprid works as a systemic neonicotinoid insecticide controls pests such but not limited to sucking pests, aphids, whiteflies and plant hoppers, which often coexist with fungal disease outbreaks.

[0012] While the individual active ingredients were known in the art, combining a systemic insecticide with both a systemic Qol fungicide and a non-systemic multi-site fungicide provides broadspectrum crop protection through a single, practical application approach capable of addressing pest such as insect pests and fungal pathogens and diseases affecting agricultural crops and while exhibiting synergistic effect and further employs lower dosages of actives.

[0013] Trifloxystrobin is a broad spectrum methoxyiminoacetate strobilurin fungicide. It pertains to a cytochrome bcl complex of quinone outside respiration inhibitor (Qol). It is used for the control of Alternaria, black root, black spot, botrytis, downy mildew, powdery mildew, leaf spot, rust, rhizoctonia stem & root rot, scab, blossom blight in various cereals, ornamentals, vegetables including carrots, asparagus, cucurbits, fruiting vegetables, root vegetables (except radish), fruit including apples, pears, grapes, strawberries, tropical crops, etc.

[0014] Further, a compound of Formula I chemically known as 2,4,5,6-tetrachloro-l,3-benzenedicarbonitrile is a non-systemic, broad-spectrum, and foliar action chloronitrile fungicide. It pertains to a multi-site activity by preventing spore germination and zoospore motility. It is used to control a range of pests such as rust, purple spot, leaf blight, Anthracnose, downy mildew, ring spot, stalk rot, botrytis rot, pod & stem blight on a wide variety of cereals, vegetables including asparagus, beans, cabbage, cauliflower, broccoli, carrot, onions, celery, cucurbits, corn for seed, fruit including cranberries, melon, mushrooms, peanuts, potatoes, etc.Moreover, imidacloprid is a neonicotinoid insecticide with systemic, contact and stomach action. It pertains to a nicotinic acetylcholine receptor (nAChR) channel blocker. It is an insecticide used for the control of plant hoppers, aphids, termites, colorado bettle, fleas, white groups, craneflies, crickets, ants on a wide variety of crops such as rice, cereals, maize, potatoes, sugar beet, lawns and turf, domestic pets, etc.

[0015] The stable synergistic pesticidal composition of the present invention will thereby targets multiple biological pathways in pest, thereby increasing mortality rates and reduces the probability of resistance and where actives in the composition are mutually compatible and also resulting in stable composition also.

[0016] Therefore, the aim of the present invention is to provide a stable synergistic pesticidal composition that addresses these needs by providing a novel composition that combines the 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] The terms "comprise / 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.

[0080] 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.

[0081] The expression of various quantities in terms of “%

[0082]

[0083] or “%” means the percentage by weight, relative to the weight of the total solution (i.e., % w / w) or volume of total solution (i.e., % w / v), composition unless otherwise specified.

[0084] 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 pests at the same time.

[0085] The term “crop” shall include a multitude of desired crop plants or an individual crop plant growing at a locus.

[0086] 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. “Bioactive amounts” as mentioned herein means that amount which, when applied for treatment of crops, is sufficient to give effect in such treatment.

[0087] The term “control” means to inhibit the ability of pests to survive, grow, feed and / or reproduce, or to limit the pests’ related damage or loss in crop plants. To “control” pests may or may not mean killing the pests although, it preferably means killing the pests.

[0088] 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 results in an increased yield and / or tolerance to abiotic or biotic stress.

[0089] 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.

[0090] According to embodiments of the present invention, the yield of the target plants treated according to the method of the invention, is increased synergistically.

[0091] According to embodiments 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.

[0092] Another indicator for the condition of the plant is the “quality” of a plant and / or its products. According to embodiments of the invention, the quality of the treated plant is increased.

[0093] In preferred embodiment of the invention, the quality of the plants treated according to the method of the invention, is increased synergistically.

[0094] 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.

[0095] 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 pests including but not limited to insects, 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 ingredientitself to facilitate absorption. Overall, increased uptake of the active ingredient results in improved performance of the product in achieving its intended purpose.

[0096] The term “FS” refers to a flowable concentrate formulation designed for seed treatment applications, wherein the active ingredients are suspended in an aqueous medium and are capable of forming a stable, uniform coating on seeds.

[0097] 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.

[0098] According to embodiments of the present invention, the yield of the treated plant is increased. According to embodiments of the present invention, there is synergistic and efficacious control of various pests affecting the plants and crops.

[0188] In one embodiment, additives such as Siloxane Polyalkyleneoxide Copolymer or 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.

[0189] In one embodiment of the present invention, Siloxane Polyalkyleneoxide Copolymer 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 pesticides, leading to improved efficacy. Siloxane Polyalkyleneoxide Copolymer 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.In one embodiment of the present invention, the inclusion of both Siloxane Polyalkyleneoxide Copolymer super-wetter and tallow amine ethoxylate in a formulation significantly enhances its surface activity and delivery efficiency. Siloxane Polyalkyleneoxide Copolymer, 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 pesticidal actives.

[0190] In one embodiment of the present invention, 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 of the present invention, 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.

[0191] In one embodiment of the present invention, Siloxane Polyalkyleneoxide Copolymer, tallow amine ethoxylate, ammonium sulphate, and epoxide soybean oil are additives used individually or in combination to enhance the performance of pesticidal formulations. Siloxane Polyalkyleneoxide Copolymer, 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 phytotoxicity. Used alone or synergistically, these additives optimize spray performance, improve bioavailability of actives, and support sustainable and effective crop protection.The said additives such as urea clathrate, Siloxane Polyalkyleneoxide Copolymer or an organosilicone based powder adjuvant, tallow amine ethoxylate, ammonium sulphate, and epoxide soybean oil either alone or in combination thereof, present in the range of 0.001 - 20% by weight of the composition.

[0423] Evaluation of synergistic effect of stable synergistic pesticidal composition of the present inventionA 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.

[0424] The synergistic action expected for a given combination of two active components can be calculated as follows:

[0425] XY

[0426] E = (X + Y) - - 100

[0427] The synergistic action expected for a given combination of three active components can be calculated as follows:

[0428] (XY+YZ+XZ) (XYZ)

[0429] E = (X + Y + Z) - + - 100 10000

[0430] Where:

[0431] 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).

[0432] X is the percentage of pesticidal control observed by the compound (Trifloxystrobin) at a defined dose (equal to x).

[0433] Y is the percentage of pesticidal control observed by the compound (Compound of Formula I) at a defined dose (equal to y).

[0434] Z is the percentage of pesticidal control observed by the compound (Imidacloprid) at a defined dose (equal to z).

[0435] When the percentage of pesticidal control observed for the combination is greater than the expected percentage, there is a synergism effect.

[0474] The treatments T1 to T28 were applied as foliar sprays, while T29 served as the untreated control. Two foliar applications were carried out at 15-day intervals, initiated when pest population reached ETL / appearance of disease in chilli plants in the experimental plots.

[0475] Observations were recorded before spraying and at 14 days after the first and second applications. From each plot, five randomly selected chilli plants were chosen. Anthracnose (Colletotrichum capsici) incidence was assessed by visual examination of leaves and fruits, and disease severity was recorded using a standard disease rating scale, which was later converted into percent disease index (PDI). Aphid (Myzus persicae) population was monitored at regular intervals by counting the number of aphids present on the top, middle, and bottom leaves of each selected plant, and the mean aphid population per plant was calculated. Based on the per cent reduction at 14 days after second spray in insect population, expected control was calculated and compared with observed control. The results of the trial have been presented here under in Table 1A.

[0530] Methodology:

[0531] 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.

[0532] Observations were recorded before spraying and at 14 days after the first and second applications. From each plot, five randomly selected chilli plants were chosen. Anthracnose (Colletotrichum capsici) incidence was assessed by visual examination of leaves and fruits, and disease severity was recorded using a standard disease rating scale, which was later converted into percent disease index (PDI). Aphid (Myzus per icae) population was monitored at regular intervals by counting the number of aphids present on the top, middle, and bottom leaves of each selected plant, and the mean aphid population per plant was calculated. Based on the per cent reduction at 14 days after second spray in insect population, expected control was calculated and compared with observed control. The per cent reduction in insect population / disease severity 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. The data were subjected to statistical analysis of variance. Results are presented in Table 2A, 2B, 2C and 2D.

[0700] From the examples above, it is clearly seen that the stable synergistic pesticidal composition of the present invention is superior for controlling the anthracnose (Colletotrichum capsica) and aphids (Myzus persicae) in chilli at 14 days after 1st& 2ndapplication (Table 2A and 2B) in chilli crop as compared to the other pesticides such as Fluopyram 21.37% w / w + Trifloxystrobin 21.37% w / w SC, Compound of Formula 175% WP and Imidacloprid 30.50 % m / m SC available in the market. The yield of chilli crop also improved in the stable synergistic pesticidal composition of the present invention comprising Trifloxystrobin 10.5% + Compound of Formula 128.8% + Imidacloprid 4.2% SC as compared to respective binary and solo compositions (Table 2C).

[0701] The disclosed stable synergistic pesticidal composition of the present invention comprising Trifloxystrobin 10.5% + Compound of Formula I 28.8% + Imidacloprid 4.2% SC @ 937.5, 1250, 1562.5 and 2500 ml / ha further showed no phytotoxicity in the chilli crop even after 1, 3, 7, 10 and 14 days after 1stapplication (Table 2D).

[0702] It is evident from the above data that the stable synergistic pesticidal composition of the present invention comprising Trifloxystrobin+ Compound of Formula 1+ Imidacloprid resulted in good control of anthracnose (Colletotrichum capsica) and aphids (Myzus persicae) in chilli 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.

[0703] From the above investigations, it will be observed that numerous modifications and variations can be effectuated without departing from the true spirit and scope of the novel concepts of the present invention. 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.
