STABLE SYNERGISTIC INSECTICIDAL COMPOSITION

FIELD OF THE INVENTION:

The present invention relates to a stable synergistic insecticidal composition comprising A) at least one anthranilic diamide insecticide or its agrochemically acceptable salts, esters and derivatives; B) Novaluron or its agrochemically acceptable salts, esters and derivatives and C) Emamectin or its agro chemically acceptable salts, esters and derivatives.

The present invention also relates to a process for preparation of such stable synergistic insecticidal composition for foliar spray treatment of plants and soil application treatment for synergistic and efficacious control 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 one of the worst enemies of crops. They cause severe damages to the crops resulting in reduced crop productivity. In heavily infested areas 80 to 90 percent crop damages has been reported. In agrarian countries like India, it badly impacts the economy of the country. Controlling crop pest population has been a major issue and various traditional and advanced means are being used to minimize the damage caused by insect pests. Most frequently and widely used method to control insect pests is use of insecticides/pesticides. Continuous use of pesticides and insecticides years after years, in uncontrolled and unscientific manner has resulted in development of resistance in the insect pests and this resistance continues to broaden in spectrum against the number of insecticides/pesticides. Continuous high intensity use of insecticides and pesticides has given rise to some other critical issues like presence of high quantity of insecticide residues in agricultural products, increasing environmental pollution and damage to ecological balance and deteriorating health of consumers.

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 pest control agent combinations have been studied, a high synergistic action has not always been found. Therefore, there is still a need for improved insecticidal composition that exhibits synergistically enhanced action, a broader scope of activity and reduced cost of treatment.

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 actives that decrease the chances of resistance and improves the spectrum of disease and insect pest control.

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. Insects are very destructive to crops and can result in significant loss of crop yield and quality, which results in economic loss to the grower and increased cost to the consumer. Combinations of insecticides are typically used to broaden the spectrum of insect control, to minimize the doses of chemicals used, to retard resistance development and to reduce the cost of treatment through additive effect. 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.

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.

Further, in general use, the insecticide actives are used in the form of a dilute aqueous composition because it can attain a good interaction with the target organism, such as plants and insects. However, most active insecticide compounds that are used as insecticides are only sparingly or even insoluble in water. The low solubility of such compounds present the challenges and difficulties to formulator in formulating insecticide compounds in stable formulations that can be easily stored for a long time and which still have a high stability and effective activity until end use. This problem especially occurs and may get worsen if more than one active compound is present in the composition. For the reasons mentioned above there is a need to provide further formulation of combination of three insecticides as actives having synergistic insect pest control properties. This object is achieved according to the invention by providing the present stable synergistic insecticidal composition.

There are various prior arts which disclose compositions comprising combination of insecticide actives with anthranilic diamide insecticide with other insecticides. Some of such prior arts are listed below:

CN101554170 discloses synergistic insecticidal composition of Chlorantraniliprole and Emamectin benzoate, with a weight ratio of 30: 1-1 :1. The insecticidal composition can be prepared into suspending agent, water dispersible granules, and microemulsion.

CN103651419 discloses a chlorantraniliprole-emamectin benzoate suspending agent and a preparation method thereof. The effective components of the composition comprisel-20% of chlorantraniliprole, 1-10% of emamectin benzoate, 3-6% of a dispersant, 0.5-3% of a lubricant, 0.1-1% of a stabilizer, 0.05-0.2% of a defoamer, 0.2-5% of a suspending agent, 3-5% of an antifreezing agent and the remaining water.

CN103651424 discloses an effervescent granule containing chlorantraniliprole and emamectin benzoate. The composition comprises the effective components of 1-20% of chlorantraniliprole, 1-20% of emamectin benzoate, 2-10% of dispersing agent, 1-5% of wetting agent and 1-5% of stabilizer, and also comprises 0.5-20% of disintegrating agent, 5-20% of acid source, 5-20% of carbon dioxide gas source, 0.01-2% of binder and the balance of inert filler, and preparation method.

CN101548680 discloses pesticidal composition containing emamectin benzoate and chlorantraniliprole. The pesticidal composition takes emamectin benzoate and chlorantraniliprole as effective constituents with mass proportion of 10: 1 to 1 :20 and the mass percentage content of the emamectin benzoate and chlorantraniliprole is between 1 percent and 50 percent. The pesticidal composition is used for preventing resistant insects in agriculture, and particularly used for preventing rice Cnaphalocrocis medinalis and the like.

CN102057933 discloses a suspending agent containing chlorantraniliprole and novaluron and a preparation method thereof. CN108432770 discloses a chlorantraniliprole synergistic composition for controlling agricultural maggot-like pests. The composition is characterized by comprising chlorantraniliprole; one of or a combination of more than one of spinetoram, dinotefuran, spinosad, novaluron and pyriproxyfen.

However, combining insecticide actives with anthranilic diamide shows compatibility issues among them and thus formulating a stable composition which provide efficacious synergistic results against insect pestsis tedious task.

Because the efficacy and chemical stability of the active ingredients and physical stability of the formulated composition may be affected by inert ingredients in the formulation, suitable inert ingredients should not cause decomposition of the active ingredient, substantially diminish its activity on application, or cause appreciable precipitation or crystal formation upon long term storage. Furthermore, inert ingredients should be non-phytotoxic and environmentally safe. Inert ingredients of formulations intended for dilution with water before application should be easily dissolved or dispersed in water.

In addition, prolonged use of single active combinations has resulted in resistance to certain particular insects, and affecting fruits yield of crops, it is therefore desired to provide an improved insecticidal composition and convenient method that is efficient against various insects including shoot borer affecting crops including vegetable crops and fruit yield, serves as good tool for resistance management, shows technical advancement over existing art and is of economic significance. Accordingly, the present invention provides a stable synergistic insecticidal composition comprising components (compounds) having different basic structures and differentfunctions 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) at least one anthranilic diamide insecticide or its agrochemically acceptable salts, esters and derivatives; B) Novaluron or its agrochemically acceptable salts, esters and derivatives and C) Emamectin or its agrochemically acceptable salts, esters and derivatives.

The present invention provides a novel method of preparing compositions comprising above mentioned active ingredients, which compositions are stable as well as provide desired bioefficacy, synergy. Embodiments of the present invention may therefore ameliorate one or more of the above-mentioned problems.

Diamide insecticides such as Anthranilic diamides are a new class of insecticides that provides good control through action on a novel target, the ryanodine receptor. Anthranilic diamides potentially activate this receptor, releasing stored calcium from the sarcoendoplasmic reticulum causing impaired regulation of muscle contraction and thus the cell death. Anthranilic diamides are an important commercial synthetic class of insecticides that bind to the ryanodine receptor with selective potency against insect versus mammalian forms of the receptor. Some of such anthranilic diamide insecticides are cyantraniliprole, tetraniliprole, cyclaniliprole, tetrachlorantraniliprole and chlorantraniliprole. The first commercialized diamide, Chlorantraniliprole, has exceptional activity against lepidopteran pests. The second anthranilamide product, cyantraniliprole, has excellent cross-spectrum activity against a range of insect orders, including both lepidopteran and hemipteran pests.

Chlorantraniliprole also known as 5-bromo-N-[4-chloro-2-methyl-6-(methylcarbamoyl)phenyl]- 2-(3 -chi oropyridin-2-yl)pyrazole-3 -carboxamide, is a anthranilic-diamide insecticide. It is effective at low use rates. It is board spectrum insecticide for the effective control of Stem borer& Leaf folder for rice, Diamond Back Moth for cabbage, American Boll warm, spotted bollworm & Tobacco caterpillar for Cotton, termite, early shoot borer & Top borer for Sugarcane, Fruit borer for Tomato & Chilli, Green semiloopers &stem fly Girdle Beetle for soyabean, Fruit and shoot borer for Brinjal, Gram pod borer & pod fly for pigeon pea, Pod borer for Bengal gram & Black gram, Fruit borer & caterpillars for Bitter gourd, Fruit borer for Okra, Spotted stem borer, pink stem borer for maize, Tobacco Caterpillar for Ground nut.

It is a high-efficiency and safe dimethylformamide pesticide. Cyantraniliprole shows action mechanism of the pesticide is to activate a ryanodine receptor (ryanodine receptor), so that intracellular calcium ions are released unlimitedly, thereby causing relaxation paralysis, activity pause and paralysis of insect muscles until the insect muscles die completely, and the pesticide can effectively prevent and treat lepidoptera, homoptera, hemiptera, coleopteran and thysanoptera pests. Cyantraniliprole has the structure provided below:

Tetraniloprole (Tetratolanilide) is a diamide insecticide belonging to anthranilamide insecticides, has an action mechanism that acts by activating ryanodine receptors in calcium release channels, causes the loss of control and paralysis of insect muscles, and can be used for preventing and treating lepidoptera, coleopteran and dipteran pests. Tetraniloprole has the structure provided below:

Cyclaniliprole is cyclic bromantraniliprole, having the chemical name: 3-bromo-N- [ 2-bromo-4- chloro-6- [ [ (1 -cyclopropyl ethyl) amine ] carbonyl ] phenyl ] -1- (3-chloro-2-pyridine) -1H- pyrazole-5-carboxamide. Cyclaniliprole has systemic activity and broad-spectrum insecticidal activity, and has good control effect on pests such as diamondback moth, prodenia litura, whitefly, aphid, thrips, liriomyza and the like. Cyclaniliprole has the structure provided below:

Tetrachlorantraniliprole belongs to a ryanodine insecticide, and is used for continuously releasing calcium ions stored in cells into sarcoplasm by combining with ryanodine receptors in pests to open calcium ion channels, and the calcium ions are combined with matrix proteins in the sarcoplasm to cause the muscle to continuously contract. Insect symptoms are manifested as convulsions, food refusal, and ultimately death. Tetrachlorantraniliprole is a low-toxicity, broadspectrum pesticide and has good activity on lepidoptera pests. The control objects comprise rice leaf rollers, chilo suppressalis, diamond back moths, asparagus caterpillars, corn borers, sugarcane borers, diamond back moths, carposina niponensis walsingham and the like.

Tetrachlorantraniliprole has the structure provided below:

Novaluron is a benzoylurea insecticide, a member of monochlorobenzenes, an aromatic ether and an organofluorine compound. Novaluron inhibits chitin formation, targeting specifically larval insect stages that actively synthesize chitin. Novaluron is a chitin synthase inhibitor active against larvae of the orders Coleoptera, Homoptera, Diptera and Lepidoptera. Chitin is only actively synthesised by the immature stages of insects resulting in good selectivity to adults of beneficial species. Novaluron is strictly a contact insecticide; it has no systemic activity. It is mainly a stomach poison and has some ovicidal activity. Novaluron belongs to a class of insecticides called insect growth regulators (IGR) that slowly kill the insects over a few days by disrupting the normal growth and development of immature insects. These IGRs affect chitin synthesis of immature insects disrupting their normal growth and development. Novaluron has low mammalian acute toxicity and has low risk to the environment and non-target organisms. Novaluron has been used on various crops including apples, aubergines, cabbage, Chinese cabbage, citrus, cotton, eggs, forestry, maize, meat, milk, ornamentals, pears, pome fruits, potatoes, stone fruits, tobacco, tomatoes, tree fruits, turf, vegetables. Novaluron has IUPAC name as N-({3-chloro-4-[(2RS)-l,l,2-trifluoro-2-(trifluoromethoxy) ethoxy] phenyl }carbamoyl)- 2,6-difluorobenzamide.

Chemical structure of Novaluron is provided below:

Emamectin is a macrocyclic lactone insecticide with low toxicity to non-target organisms and the environment, and is considered an important component in pest-management programmes for controlling field crop pests. Emamectin is the 4”-deoxy-4”-methylamino derivative of abamectin, a 16-membered macrocyclic lactone produced by the fermentation of the soil actinomycete Streptomyces avermitilis. Emamectin belongs to the avermectin family, which exhibit toxicity for nematodes, arthropods, and several other pests. Emamectin is derived from avermectin Bl, also known as abamectin, a mixture of the natural avermectin Bia and Bib. Emamectin, produced by the bacterium Streptomyces avermitilis, belongs to the avermectin family of compounds all of which exhibit toxicity for nematodes, arthropods, and several other pests. The benzoate salt of emamectin in particular has found widespread use as an insecticide and is approved by the EPA for use in prevention of emerald ash borer in ash trees. Emamectin works as a chloride channel activator by binding gamma aminobutyric acid (GABA) receptor and glutamate-gated chloride channels disrupting nerve signals within arthropods. Emamectin is widely used in controlling lepidopterous pests (order of insects that as larvae are caterpillars and as adults have four broad wings including butterflies, moths, and skippers) in agricultural products. Chemical structure of Emamectin is provided below:

Emamectin benzoate is the 4'-deoxy-4'-epi-methyl-amino benzoate salt of avermectin Bl (abamectin), which is similar structurally to natural fermentation products of Streptomyces avermitilis. Emamectin benzoate is being developed as a newer broad-spectrum insecticide for vegetables and has a very low application rate. The mechanism of action involves stimulation of high-affinity GABA receptors and a consequent increase in membrane chloride ion permeability.

Emamectin benzoate with the chemical name of 4 '-methylamino-4' -deoxyabamectin Bl benzoate is a novel high-efficiency semisynthetic antibiotic type insecticidal and acaricidal biopesticide developed based on a fermentation product abamectin Bl, and the action mechanism of the emamectin benzoate is to interfere the nerve physiological activity of insects, stimulate and release gamma-aminobutyric acid and inhibit the conduction of nerve impulse of the insects. Emamectin benzoate has the structure shown below:

The term Emamectin technical used in the present description does include and mean Emamectin Benzoate.

Evaluation of synergistic effect of insecticidal 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.

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 pesticidal control for the combination of the two or three active ingredients at defined doses (for example equal to x, y and z, respectively).

X is the percentage of insecticidal control observed by the compound (Chlorantraniliprole) at a defined dose (equal to x).

Y is the percentage of insecticidal control observed by the compound (Novaluron) at a defined dose (equal to y).

Z is the percentage of insecticidal control observed by the compound (Emamectin Benzoate) 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.

The treatments T1 to T34 were applied as foliar spray and in T35 control treatment only water was sprayed. Transformations of insect data were made where necessary. The data thus obtained were analyzed from ten plants per replication.

Post- treatment damaged shoots were recorded at suitable intervals (7 and 14 days) after each spray and mean damage % is calculated. Corrected % reduction (Observed Control) over control was worked out using Abott’s Formula (1925).

Corrected % reduction =

(% damaged shoots in Treatment)

1 - > x 100

Based on corrected % reduction against control in solo treatments the Expected control was calculated and compared with Observed control. The results of the trial have been presented here under in Table 1.

Table 1: Synergistic effect of combination product of the present invention (Chlorantraniliprole + Novaluron + Emamectin Benzoate) against shoot borer in brinjal crop

It is clearly evident from the data shown in above Table 1 for per cent shoot borer control in brinjal crop that the ternary combination composition of the present invention comprising Chlorantraniliprole, Novaluron and Emamectin Benzoate T1 to T5 are highly synergistic with > 1 Colby’s Ratio. The binary combination of two insecticides Chlorantraniliprole + Novaluron

(T6 to T10), Chlorantraniliprole + Emamectin Benzoate (Ti l to T15) and Novaluron + Emamectin Benzoate (T16 to T20) are compatible but non-synergistic for the control of shoot borer as compared to ternary combination of Chlorantraniliprole, Novaluron and Emamectin Benzoate. The binary combinations of two insecticides are thus less effective to control shoot borer as compared to ternary combination of three insecticides Chlorantraniliprole + Novaluron + Emamectin Benzoate (T1 to T5).

Experiment for Bio-efficacy evaluation of combination product of present invention:

For the ternary combination based on Chlorantraniliprole, Novaluron and Emamectin Benzoate evaluation under field conditions, the basic test composition as Chlorantraniliprole 18.50 % SC, Novaluron 10% EC and Emamectin Benzoate 5% WDG available in the market. For trinary combination, Chlorantraniliprole 4.5% + Novaluron 11.5% + Emamectin Benzoate 1.5% SC; Chlorantraniliprole 4.5% + Novaluron 11.5% + Emamectin Benzoate 1.5% SE and Chlorantraniliprole 4.5% + Novaluron 11.5% + Emamectin Benzoate 1.5% ZC were used. The solo formulations of Chlorantraniliprole 18.50 % SC, Novaluron 10% EC and Emamectin Benzoate 5% WDG along with binary combination formulation Novaluron 5.25 % + Emamectin benzoate 0.9 % w/w SC and solo formulation Flubendiamide 39.35 % w/w SC available in the market were used for comparison.

Methodology:

All the treatments were imposed by high volume knapsack sprayer fitted with hollow cone nozzle on first appearance of insect incidence on Brinjal plants. During the study period, two sprays were given at 15 days’ interval. Observation on damaged shoots (%)for fruit and shoot borer (FSB) were taken at seven and fourteen days after the application on ten plants per treatment per replication and mean is presented after each spray. For damaged fruits (%) recorded at picking. Corrected % reduction (Observed Control) over control was worked out using Abott’s Formula (1925).

The crop yield was recorded at each harvest and cumulative yield has been expressed as q/ha.

The observations for phyto-toxicity symptoms on brinjal crop at 1, 3, 7 and 10 days after each spray were also recorded.

Based on treatment application cost, market price of produce and net profit, the Cost: Benefit Ratio was calculated for the economics of ternary combination treatments. The data were subjected to statistically analysis of variance. Results are presented in Tables 2 to 5.

Results:

The results for fruit and shoot borer (FSB) incidence on brinjal crop recorded during the experimental period and per cent reduction over untreated control are summarized in Table 2 and 3. The data on yield is presented in Table 4. The observations recorded for phytotoxicity symptom is presented in Table 5.

Benefit Ratio in Brinjal

Table 5: Phytotoxicity evaluation of synergistic composition of present invention on brinjal plants

From the example, it evident that the synergistic compositionof the present invention is better inprotecting brinjal crop from fruit and shoot borer (Table 2 and 3) in comparison to registered solo formulations available in market and other market standard products comprising Chlorantraniliprole 18.50 % SC, Novaluron 10% EC, Emamectin Benzoate 5% WDG, Novaluron 5.25 % + Emamectin benzoate 0.9 % w/w SC and Flubendiamide 39.35 % w/w SC at registered dosage levels.

The yield of marketable brinjal fruit also improved in the ternary combination of Chlorantraniliprole 4.5% + Novaluron 11.5% + Emamectin Benzoate 1.5% SC as compared to binary and solo components (Table 4). One of the reasons of higher marketable crop yield may be due to better control of shoot and fruit borer. The Cost: Benefit Ratio revealed that ternary combination Chlorantraniliprole 4.5% + Novaluron 11.5% + Emamectin Benzoate 1.5% SE was most economical with higher Cost: Benefit Ratio followed by SC and ZC formulation as compared to other binary and solo treatments (Table 4). The disclosed combination Chlorantraniliprole 4.5% + Novaluron 11.5% + Emamectin Benzoate 1.5% SC @ 625 and 1250 ml/ha further showed no phytotoxicity in the brinjal crop after 1, 3, 7 and 10 days after each spray (Table 5). It is evident from the above tables of examples that the composition of the present invention Chlorantraniliprole 4.5% + Novaluron 11.5% + Emamectin Benzoate 1.5% SC resulted in efficient control of Fruit & Shoot Borer (Leucinodes orbonalis) with higher yield as compared to the reference standard products (binary compositions and solo products). The Cost: Benefit Ratio also showed that ternary combination Chlorantraniliprole 4.5% + Novaluron 11.5% + Emamectin Benzoate 1.5% in different formulations types was most economical with higher Cost: Benefit Ratio as compared to other binary and solo treatments.
