Description

[0001] STABLE SYNERGISTIC INSECTICIDAL COMPOSITION FIELD OF THE INVENTION The present invention relates to stable synergistic insecticidal composition for the control of plant and crop pests including wide variety of insect pests. More particularly, the present invention relates to a stable synergistic insecticidal composition comprising A) Compound of Formula I, chemically known as 5-amino-1-(2,6-dichloro-α,α,α-trifluoro-p-tolyl)-4-[(RS)- (trifluoromethyl)sulfinyl]-1H-pyrazole-3-carbonitrile or its agrochemically acceptable salts, esters and derivatives; B) Compound of Formula II, chemically known as 2-[1-methyl-2-(4- phenoxyphenoxy)ethoxy] pyridine or its agrochemically acceptable salts, esters and derivatives and C) Spinosad or its agrochemically acceptable salts, esters and derivatives. The present invention also relates to a process for preparation of such stable synergistic insecticidal composition for synergistic and efficacious control of wide variety of insect pests. BACKGROUND OF THE INVENTION 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 present invention, or that any publication specifically or implicitly referenced is prior art. Insect pests are among the most damaging enemies of crops. They cause severe crop damage, resulting in lower crop productivity. Crop damage of 80 to 90 percent has been reported in heavily infested areas. It has a negative impact on the economy of agrarian countries such as India. Controlling crop pest populations has been a major issue, and various traditional and advanced methods are being used to minimise the damage caused by insect pests. Continuous use of pesticides and insecticides in an uncontrolled and unscientific manner over the years has resulted in the development of resistance in insect pests, and this resistance continues to broaden in spectrum against a number of insecticides / pesticides. Continuous high-intensity insecticide and pesticide use has resulted in other critical issues such as the presence of large amounts of insecticide residues in agricultural products, increased environmental pollution and damage to ecological balance, and deteriorating health of consumers. With the onset of resistance to certain insect pests, there is a need in the art for a combination of actives that decrease the chances of resistance and improves the spectrum of disease and pest control. To control insect pests, it is necessary to spray and use an insecticidal composition, effective for target insect pests at appropriate times throughout the cultivation period and insect life cycle. In the practice of pest control, particularly insect control, there are two main factors which determine the effectiveness of the treatment; 1) immediate action on the pests (known in the art as "knock- down action"), 2) long term action (known also as "residual action"). The effective insecticidal composition for insect control ought to qualify both these factors. It is always preferable to be able to reduce the amount of chemical agents released into the environment while still ensuring effective pest control. Although insect pest control agent combinations have been studied, a high synergistic action has not always been found. There is however a need for improvement of these combinations. Single active compositions used over a long period of time has resulted in resistance. With the onset of resistance to certain pests, there is a need in the art for a combination of insecticidal actives that decrease the chances of resistance and improves the spectrum of disease and insect pest control. Combination of insecticides are used to broaden the spectrum of control of insect, to improve the insect control with synergistic effect, reduce dosage, thereby reducing environmental impact, to broaden the spectrum of control, decrease chances of development and management of resistance and to enhance residual control so lesser the number of sprays for crop protections and minimizing the insecticidal load in ecosystem. The combination of insecticides at times demonstrates an additive or synergistic effect that results in an improved control on the pests. Although, many combinations of insecticidal agents have been studied, a synergistic effect is rarely attained. Therefore, there is still a need for novel insecticidal composition comprising combination of insecticides which have different chemistry but are broad spectrum to cover efficacious control of large number of insect pests, which also exhibits synergistically enhanced action, a broader scope of activity at a reduced cost of treatment. Further, insecticidal compositions that can be applied at as low a dose as possible and be effective in controlling pest species of insects while causing as little harm as possible to beneficial insects and minimal disturbance in the environment are in demand by the farming community. Therefore, there is a need for an insecticidal formulation that is highly efficient, non- toxic, covers a broader spectrum of insects and is environment friendly and economical. Accordingly, there exists a continuous need for new insecticidal combinations to be applied so as to provide an economical and effective solution in terms of insect control, yield, plant growth, broader crop protection spectrum, reduce the burden on the environment / farmers, healthy foliage, saves labour cost and is yet cost-effective to the end user. There are many combinations of insecticides along with other insecticides are known in the art for the control of insect pests. For example, reference may be made to CN113575603 which discloses Suspoemulsion formulation of Fipronil and Pyriproxyfen for controlling insects. Further, reference can be made to CN110402922 which discloses an insecticidal suspending agent, in particular to fipronil and Dimethomorph mixed pesticide suspending agent, belonging to the field of pesticides and preparations thereof. Conventional combinations comprising Fipronil and Pyriproxyfen showing insecticidal properties sometimes do not show a practically sufficient control effect on complex insect pests since it has an insufficient effect on particular complex insects or its residual effectiveness lasts for a relatively short period. Thus, there is limited spectrum of insecticidal diseases. Further, the risk of resistance development with use of specific type of insecticide is pronounced when used for a long period of time. Thus, there exists a need in the art for a composition comprising insecticides having different chemistry which show superior and effective control of broad range of insect pests. There is however a need for improvement of these combinations. Single active combinations used over a long period of time has resulted in resistance. With the onset of resistance to certain insects, there is a need in the art for a combination of insecticidal actives that decreases chances of resistance and improves the spectrum of disease and insect pest control. Therefore, one object of the present invention is to provide synergistic insecticidal composition for the control of broad range of insect pests including but not limited to thrips, aphids, white fly, mites, stem borer, chewing pests and entire sucking pests complex, which are resistant to existing insecticidal compositions and have prolonged and sustained insect pest control. Accordingly, the present invention provides a stable synergistic insecticidal composition comprising components (compounds) having different basic chemical structures and different functions with well-suited to each other, and a method for controlling plant insect pests. Therefore, the present invention provides a stable synergistic insecticidal composition comprising A) Compound of Formula I, chemically known as 5-amino-1-(2,6-dichloro-α,α,α-trifluoro-p-tolyl)-4- [(RS)-(trifluoromethyl)sulfinyl]-1H-pyrazole-3-carbonitrile or its agrochemically acceptable salts, esters and derivatives; B) Compound of Formula II, chemically known as 2-[1-methyl-2-(4- phenoxyphenoxy)ethoxy] pyridine or its agrochemically acceptable salts, esters and derivatives; and C) Spinosad or its agrochemically acceptable salts, esters and derivatives. Compound of Formula I, chemically known as 5-amino-1-(2,6-dichloro-α,α,α-trifluoro-p-tolyl)-4- [(RS)-(trifluoromethyl)sulfinyl]-1H-pyrazole-3-carbonitrile is a phenylpyrazole insecticide, which has an action mechanism of combining with a gamma-aminobutyric acid receptor, effectively blocks a chloride ion channel regulated by gamma-aminobutyric acid of an insect central nervous system which interferes with the insect central nervous system, and causes over excitation of insect nerves and muscles until death. It kills insects when they eat it or come in contact with it and then disrupting the normal function of the central nervous system of insects. It is more toxic to insects than people and pets because it is more likely to bind to insect nerve endings. Its chemical structure is provided below:

[0002] Compound of Formula I Compound of Formula II, chemically known as 2-[1-methyl-2-(4-phenoxyphenoxy)ethoxy] pyridine is a solid compound having (melting point in 48-50°C) with low volatility and only slightly soluble in water. It is a juvenile hormone analog and an insect growth regulator. It prevents larvae from developing into adulthood and thus rendering them unable to reproduce. It is effective against various harmful insects or pests, including fleas, cockroaches, ticks, ants, carpet beetles and mosquitoes. Its chemical structure is provided below: Spinosad is a is derived from a species of Actinomycetes bacteria; Saccharopolyspora spinosa. The active components are a mixture of spinosad A and spinosad D, which has high-efficiency preventing and controlling activity against lepidopteran pests, some Diptera (mosquitoes, flies and the like), Coleoptera, Hymenoptera and Thysanoptera pests. Spinosad has a unique insecticidal mechanism, which prevents it from cross- resistance with other insecticides. It mainly acts on the target of the nicotinic acetylcholine receptor (nAChR) of insects. Spinosad is both a nerve poison and a stomach poison, so it kills pests that it contacts and those that consume it on the foliage they eat. However, studies have shown that Spinosad has little cross-resistance with neonicotinoid insecticides that also act on nAChR. Spinosad has a high environmental safety, its leaching and volatility in water is very weak, and will not cause pollution to groundwater and the atmosphere, its photodegradation half-life in water is less than 1 day. Spinosad has low toxicity to non-target organisms, will not kill natural enemies, has extremely low toxicity to birds, is safe for human and mammals, has no teratogenic, mutagenic or carcinogenic effects. Its chemical structure is as under:

Synergism was calculated by using Colby’s method (Weeds, vol.15 No.1 (Jan 1967), pp.20-2. The synergistic action expected for a given composition of two active components can be calculated as follows: XY E = (X + Y) – --------- 100 The synergistic action expected for a given composition of three active components can be calculated as follows: (XY+YZ+XZ) (XYZ) E = (X + Y + Z) – ----------------- + ------------ 100 10000 Where: E represents expected percentage of insecticidal control for the composition of the two or three actives ingredients at defined doses (for example equal to x, y and z, respectively). X is the percentage of insecticidal control observed by the compound (Spinosad) at a defined dose (equal to x). Y is the percentage of insecticidal control observed by the compound (Compound of formula I) at a defined dose (equal to y). Z is the percentage of insecticidal control observed by the compound (Compound of formula II) at a defined dose (equal to z). When the percentage of insecticidal control observed for the composition is greater than the expected percentage, there is a synergism effect. Observed control (%) Ratio = ----------------------------- Expected control (%) 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.
