Description

[0001] STABLE SYNERGISTIC INSECTIDAL 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) Isoxazoline insecticide selected from Fluxametamide or Isocycloseram or its agrochemically acceptable salts, esters or its derivatives; B) Abamectin or its agrochemically acceptable salts, esters and derivatives; and C) at least one insecticidal compound selected from Deltamethrin or Lambda-cyhalothrin 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 presently claimed invention. 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 insects, to improve the insect pest control with synergistic effect, reduce dosage, thereby reducing environmental impact, 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 pesticidal load in ecosystem. 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. 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 including complex sucking pests which also exhibits synergistically enhanced action, a broader scope of activity at a reduced cost of treatment. 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 or fungicides known in the art for the control of insect pests. For example, reference may be made to CN110199999A relates to a pesticidal binary composition containing Fluxametamide and Tolfenpyrad wherein weight ratio of Fluxametamide to Tolfenpyrad is 10:1 to 1:5. The said composition comprises the active ingredients, and the balance of assistants. Reference may also be made to another composition disclosed in AU2021102687 which relates to a composition including Deltamethrin as an active agent and piperonyl butoxide as a synergist. The said invention disclosed in AU2021102687 also relates to methods of preparing and using composition including Deltamethrin as an active agent and piperonyl butoxide as a synergist However, combining Flonicamid and Abamectin have very little impact on the chewing and entire sucking pests’ complex including thrips, mites, stem borer, leaf hoppers. Also, some insect pests show resistance towards the formulations comprising Flonicamid and Abamectin as actives. 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 insect pests including but not limited to thrips, mites, stem borer, chewing pests and entire sucking pests complex, which are resistant to existing insecticidal compositions and have prolonged insect pest control. Fluxametamide belong to the chemical group of isooxazoline and has the chemical name as N 4- [(RS)-5-(3,5-dichlorophenyl)-4,5-dihydro-5-(trifluoromethyl)isoxazol-3-yl]-N-[(EZ)- (methoxyimino)methyl]-o-toluamide or 4-[5-(3,5-dichlorophenyl)-4,5-dihydro-5- (trifluoromethyl)-3-isoxazolyl]-N-[(methoxyamino)methylene]-2-methylbenzamide. Fluxametamide potently inhibit the specific binding of [3H]EBOB, [3H]4′-ethynyl-4-n- propylbicycloorthobenzoate to housefly-head membranes, suggesting that Fluxametamide affects insect γ-aminobutyric acid (GABA)-gated chloride channels (GABACls). The chemical structure of Fluxametamide is provided below: Fluxametamide Abamectin is an insecticide belongs to the class of avermectin. It has a low aqueous solubility and is not volatile. It does not tend to be persistent in the environment. The action mechanism is to stimulate the release of a nerve transmission medium, namely r-aminobutyric acid, and interfere normal neurophysiological activities. Due to the osmosis, the influence of rainwater is small, and the fertilizer is safe to crops. Abamectin is adsorbed by soil in soil and cannot move and is decomposed by microorganisms, so that the abamectin has no accumulation effect in the environment and can be used as a component of comprehensive control. It mainly controls phytiphagus mites, leafminers, cockroachers, ants, pear psylla, nematodes including Meloidogyne spp It is used in wide variety of crops. It is used to kill insect pests in ornamental plants; fruit including citrus, pears, tomatoes, watermelon; Cotton; vegetable crops including eggplant, curcubits, beans. The structure of abamectin is shown as below: Abamectin Deltamethrin belongs from Pyrethroid insecticide class, which mimics the natural insecticidal properties of pyrethrins derived from chrysanthemum flowers. It acts upon contact with target pests, disrupting their nervous system and causing paralysis. Additionally, it possesses residual activity, providing long-lasting protection against re-infestation. It interferes with the sodium channels in the nervous system of insects, leading to hyper excitation and eventual paralysis. It’s IUPAC name is (S)-α-cyano-3-phenoxybenzyl (1R,3R)-3-(2,2-dibromovinyl)-2,2- dimethylcyclopropanecarboxylate. Chemical structure of Deltamethrin is provided below: Deltamethrin Lambda-Cyhalothrin is a non-systemic contact and stomach action and repellent properties. It gives a rapid knock down and long residual activity. It is used to central a wide variety of insect pests like aphids, thrips, Lepidoptera larvae, Coleoptera larvae and adults in cereals, ornamentals, potatoes, vegetables, cotton and other crops. It provides very good control of insect borne plant viruses and also used for control of insect pests in public health.

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. The expression of various quantities in terms of “% w / w” or “%” means the percentage by weight, relative to the weight of the total formulation or composition unless otherwise specified. The term “active ingredient” (a.i.) or “active agent” used herein refers to that component of the composition responsible for control and killing of pest. The terms “plants” and “vegetation” include, but are not limited to, germinant seeds, emerging seedlings, plants emerging from vegetative propagules, and established vegetation. 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. “Bioactive amounts” as mentioned herein means that amount which, when applied for treatment of crops, is sufficient to give effect in such treatment. 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. 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. The above identified indicators for the health condition of a plant may be interdependent or they may result from each other.

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 combination of two active components can be calculated as follows: XY E = (X + Y) – --------- 100 The synergistic action expected for a given combination 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 combination 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 (Fluxametamide) at a defined dose (equal to x). Y is the percentage of insecticidal control observed by the compound (Abamectin) at a defined dose (equal to y). Z is the percentage of insecticidal control observed by the compound (Deltamethrin / Lambda cyhalothrin) at a defined dose (equal to z). When the percentage of insecticidal control observed for the combination 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. Experiment for Synergistic activity of Combination product of present invention: Example 1 - Details of experiment on Chilli crop: Field experiment for synergistic activity of Fluxametamide, Abamectin and Deltamethrin for the control of Fruit borer and yellow mite pest in chilli crop was conducted at farmer field, Palghar (Maharashtra). To evaluate the synergistic effect, Chilli (Variety Pusa Jwala) crop was sown in 5 m x 5 m plots at 75 cm x 75 cm plant distance with three replications and in Randomized Block Design (RBD). The treatments were applied as foliar application in the form of EC formulation @ 500 ml / ha. Each active component was applied at recommended dose in different ternary and binary compositions, Solo compositions was also taken for comparison.

Other registered formulated products available in the market, Fluxametamide 10% w / w EC, Abamectin 1.9% EC and Deltamethrin 11% w / w EC were also evaluated and were observed to be less effective in comparision to the ternary composition of the present invention. The yield of Chilli crop also improved in the ternary composition of Fluxametamide 7.3% + Abamectin 1.8% + Deltamethrin 2.9% EC as compared to binary and solo compositions (Table 4). The disclosed exemplary composition Fluxametamide 7.3% + Abamectin 1.8% + Deltamethrin 2.9% EC @ 375ml, 500ml, 625ml and 1000ml / ha further showed no phytotoxicity in the chilli crop even after 0, 3, 5, 7, 10 and 15 days after spray (Table 6). It is evident from the above tables of examples that the ternary composition of the present invention Fluxametamide, Abamectin and Deltamethrin resulted in good control in fruit borer and yellow mite in Chilli crop with higher respective yields as compared to the reference standard products (binary compositions and solo products). Hence, the composition of present invention has resulted in synergistic effect and is bio-efficacious. Example 4 - Evaluation of the composition of the present invention on Chilli The synergistic composition of the present invention Fluxametamide 7.3% + Abamectin 1.8% + Lambda cyhalothrin 2.4% EC was evaluated on Chilli crop. The treatments application was done on at initiation of insect-pest in plots sown in Randomized Block Design (RBD) with three replications maintaining a distance of 75 cm x 75 cm between plants and rows. The observations were recorded for the following objectives. Objectives: 1. Bio-efficacy evaluation against fruit borer on Chilli crop. 2. Bio-efficacy evaluation against yellow Mite on Chilli crop. 3. Bio-efficacy evaluation based on per cent reduction in fruit borer over control. 4. Bio-efficacy evaluation based on percent reduction in yellow mite population. 5. Bio-efficacy evaluation based on green Chilli yield. 6. Phytotoxicity evaluation on Chilli crop.

The treatments were applied as foliar application at the ETL level of insect population. Each active component was applied in different ternary and binary compositions. Solo compositions were also taken for comparison. Observations for Fruit borer (Helicoverpa armigera) and yellow mite (Polyphagotarsonemus latus) were recorded at Before spray, 7 and 15 days after sprays by observing 10 random plants per plot and based on number of fruit borer and yellow mite, percent reduction over control was calculated. The fruit yield Chilli was recorded at different picking as per harvest. The observations 5 for phytotoxicity to Chilli crop at 0, 3, 7, 10 & 15 days after spray were also recorded.
