BACKGROUND OF THE INVENTION:
Pests including insects can have adverse and damaging impacts on agricultural production by affecting crops and food production. In addition, pests can have detrimental effect on environment and human health. Insecticide or pesticides are used widely and very frequently in commercial agriculture and have enabled an enormous increase in crop yield and product quality which is ultimately advantageous to the farmers economically. In order to control pests of plant, various pesticides or combination of pesticides are being used by farmers. Combination of insecticides are used to broaden the spectrum of control of insect, to improve the pest control with synergistic effect, reduce dosage, thereby reducing environmental impact, to broaden the spectrum of control, i.e. chewing and sucking insects including leafhoppers and panthoppers at a time, 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, especially Leptocorisa species of insects (mostly known as "rice bugs" or gundhi bugs) and hoppers 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 that exhibits synergistically enhanced action, a broader scope of activity and reduced cost of treatment.
Rice, being staple crop in India, is seen to be attacked by various species of pests. The most common ones being Rice bugs (Gundhi bugs), Leafhoppers and plant hoppers-which are sucking insects that remove sap from the xylem and phloem tissues of the plant. High population infestations severely damage plants. Gundhi bug is a pest of rice. It damages the crop by sucking out the contents which develop grains from pre-flowering spikelets. They are on the soft dough stage and cause filled or empty grains and discolouration. The rice bugs feed on rice grains at its immature and adult stage. They are found near factors such as extensive weedy areas, wild grasses, near canal Woodlands, and rice planting. The adult rice bugs are active during the day and early morning. They hide in grasses during bright sunlight. They are left unnoticed. They create deformed or sporty grains, erect panicles, and shrivelled grains. They can be serious pests of rice and sometimes reduce yield by as much as 30%.
Hopper damage is called “hopper burn” because plants dry up and take on the orange-yellowish to brownish appearance of plants that have been damaged by fire. Symptoms of hopper burn include: Hopperburn or yellowing, browning and drying of plant; Circular patches of drying and lodging of matured plant; Nymphs and adults congregate at the base of the plant above the water level; Affected plant dries up and gives a scorched appearance called “hopper burn”.
In addition to causing hopperburn, these insects are also vectors of various rice virus diseases, such as rice tungro virus transmitted by the green leafhopper. Depending on the species and prevailing conditions, leafhoppers may go through one to three generations per year. Those species passing through several generations per year are generally the most serious, as their numbers can increase dramatically throughout the season.
In order to control sucking pests including rice bugs and hoppers affecting rice crop plant, several pesticides or combinations of pesticides have been developed and are currently in use for example pesticides such as acephate, buprofezin, dichlorovos, ethofenprox, imidacloprid, thiamethoxam; combination of pesticides such as deltamethrin and buprofezin, ethiprole and imidacloprid, buprofezin and acephate etc. However, such pesticides or combination of pesticides show reduced efficacy against sucking pests of rice including rice bugs and hoppers due to development of resistance to said pesticides or combination of pesticides. Therefore, there is a need to develop a synergistic insecticidal compositions comprising combination of insecticides to protect and cure aforementioned pest infestations, which have the following advantages and effects:
• use lower dosage of individual insecticides, are applied at lower dosage,
• have prophylactic and curative action,
• quick known down effect against the rice pests such as rice bugs and hoppers
• reduced or not phytotoxicity and imparting of greening effect to crops;
• involves application of lesser number of spray rounds which mean longer spells of pest free crop;
• promotes and provides higher yield of crop and is cost effective;
• aids in resistance management
Certain applications disclose certain combinations of insecticides but their compositions post a lot of issues.
For instance, reference may be made to CN102228050A, wherein it is provided a synergistic pesticide composition and further provides a preparation method and purposes of the composition. The composition is a mixture comprising compound (A) Dinotefuran and compound (B) Nitenpyram. The pesticide composition provided in the invention has high insecticidal efficiency and can effectively control insects on a plurality of crops like paddy rice, fruit trees and vegetables. However, there is a limited scope for such type of insecticidal applications and is not broad spectrum and also the build of resistance for such insecticide is relatively fast.
Reference may be also made to CN101720769A, wherein it is provided a novel composition and a preparation method and application thereof, wherein the insecticidal composition is a mixture comprising a compound (A), i.e., pymetrozine and a compound (B), i.e. chlorantraniliprole.
Reference may be made to CN101480193A, wherein the patent relates to a composition containing Nitenpyram. The composition further comprises bifenthrin, high-efficiency Lambda-cyhalothrin, Banleptm, Hexaflumuron, Isoprocorb and balance solvent or auxiliary agent useable and acceptable in pesticide.
Reference may be made to US20040220199A1, wherein the patent relates to a composition that includes a combination of at least one pyrethrin or synthetic pyrethroid and at least one other insecticide selected from the group consisting of an oxadiazine derivative, a chloronicotinyl, a nitroguanidine, a pyrrol, a pyrazone, a diacylhydrazine, a triazole, a biological/fermentation product, a phenyl pyrazole, an organophosphate and a carbamate, wherein the chloronicotinyl comprises at least one compound that is selected from the group consisting of imidacloprid, acetamiprid, nitenpyram, and mixtures thereof.
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 pests, there is a need in the art for a combination of actives that decreases chances of resistance and improves the spectrum of disease and pest control.
It is therefore desired to provide an improved insecticidal composition and convenient method that is efficient against sucking pests of various crops and plats including rice, serves as good tool for resistance management, shows technical advancement over existing art and is of economic significance.
OBJECT AND ADVANTAGES OF THE INVENTION:

Nitenpyram
Nitenpyram is an insecticide used in agriculture and veterinary medicine to kill external parasites of pets. It is a neonicotinoid, a neurotoxin that blocks neural messages and binds particularly tightly in the central nervous system of insects, causing rapid death.
Nitenpyram is a C-nitro compound consisting of 2-nitroethene-1,1-diamine where one of the nitrogens bears ethyl and (6-chloro-3-pyridinyl)methyl while the other nitrogen carries a methyl group. It has a role as a neonicotinoid insectide. It is a C-nitro compound and a monochloropyridine. It derives from a 2-chloropyridine.
It has an IUPAC name as (E)-1-N'-[(6-chloropyridin-3-yl) methyl]-1-N'-ethyl-1-N-methyl-2-nitroethene-1,1-diamine having chemical structure as:
Nitenpyram is in the class of neonicotinoid insecticides. It enters the systemic circulation of the adult flea after consuming blood from a treated animal. It binds to nicotinic acetylcholine receptors in the postsynaptic membranes and blocks acetylcholine-mediated neuronal transmission causing paralysis and death of the flea. Nitenpyram is 3500x more selective for insect alpha-4beta-2 nicotinic receptors than in vertebrate receptors. It does not inhibit acetylcholinesterase.
Pymetrozine
Pymetrozine is a member of the class of 1,2,4-triazines [from a chemical class (pyridine azomethines)] that is 4,5-dihydro-1,2,4-triazin-3(2H)-one substituted by a methyl group at position 6 and a (pyridin-3-ylmethylidene)amino group at position 4. It has a role as an antifeedant, an environmental contaminant, a xenobiotic and a TRPV channel modulator. It is a member of 1, 2, 4-triazines and a member of pyridines.
It has an IUPAC name as 6-methyl-4-[(E)-pyridin-3-ylmethylideneamino]-2,5-dihydro-1,2,4-triazin-3-one having chemical structure as
Pymetrozine is the only representative of the pyridine azomethines, a novel class of insecticides, highly active and specific against sucking pests such as whiteflies, hoppers and aphids. It has a unique mode of action and can be applied as both foliar and soil application. It has no direct toxicity against insects, but it blocks stylet penetration of sucking pests, which may cause immediate and irreversible cessation of feeding within few hours of application of the pesticide, followed eventually by starvation and death. Even if insertion of the stylet into plant cells is achieved, it takes considerably more time than normal, and pest can ingest sap only for a short time. Mortality is slow and depending on the climatic conditions, treated pests may appear normal for several days before they die from starvation.
The mode of action of pymetrozine in insects has not been precisely determined biochemically, but it may involve effects on neuroregulation or nerve-muscle interaction. Physiologically, it appears to act by preventing these insects from inserting their stylus in to the plant tissue. It provides immediate crop protection through permanent feeding inhibition of insects. It binds to the neuronal receptors, which act on the nervous system creating a nervous inhibition of feeding capability in the insects. This action also prevents the aphid from transmitting virus material into the plant. highly active and specific against sucking insect pests field crops, vegetables, ornamentals, cotton, hop, deciduous fruit, and citrus, and of the brown planthopper, in rice.
Fenobucarb
Fenobucarb is a carbamate ester obtained by the formal condensation of 2-sec-butylphenol with methylcarbamic acid. It has a role as an EC 3.1.1.7 (acetylcholinesterase) inhibitor, an agrochemical, a herbicide, an insecticide and an environmental contaminant. It derives from a methylcarbamic acid and a 2-sec-butylphenol. Fenobucarb is also widely known as BPMC. Fenobucarb is used as insecticide especially for control of Hemipteran pests, on rice and cotton.
It has an IUPAC name as (2-butan-2-ylphenyl) N-methylcarbamate having chemical structure as:
Fipronil
Fipronil 5-amino-1- [2,6-dichloro – 4 -(trifluoromethyl) phenyl]-4-[(trifluoromethyl) sulfinyl]-1H-pyrazole-3-carbonitrile is a member of the class of pyrazoles that is 1H-pyrazole that is substituted at positions 1, 3, 4, and 5 by 2,6-dichloro-4-(trifluoromethyl)phenyl, cyano, (trifluoromethyl)sulfinyl, and amino groups, respectively. It is a nitrile, a dichlorobenzene, a primary amino compound, a member of pyrazoles, a sulfoxide and a member of (trifluoromethyl) benzenes.
It has an IUPAC name as 5-amino-1-[2, 6-dichloro-4-(trifluoromethyl) phenyl]-4 (trifluoromethylsulfinyl) pyrazole-3-carbonitrile and having chemical structure as:
The mechanism of action of fipronil is complex and involves multiple interactions of both parent fipronil and its oxidation product, fipronil sulfone, on GABA-gated and glutamate-gated chloride channels in the insect nervous system. Both fipronil and fipronil sulfone inhibit GABA receptors as well as desensitizing and nondesensitizing GluCls.The net result of insect exposure to fipronil is blockade of inhibitory nerve transmission, resulting in hyper excitability and death of susceptible parasites.
In one aspect of the present invention, the synergistic insecticidal composition comprises bioactive amounts of (A) Nitenpyram in the range of about 0.5 to 40% w/w of the composition; (B) Pymetrozine in the range of about 0.5 to 50% w/w of the composition; and (C) Fipronil or Fenobucarb in the range of about 0.5 to 50% w/w of the composition.

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 in the proper sense, 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.
In an especially preferred embodiment of the invention, the yield of the treated plant is increased.
In another preferred embodiment of the invention, the yield of the plants treated according to the method of the invention, is increased synergistically.
According to the present invention, "increased yield" of a plant, in particular of an agricultural, silvicultural and/or horticultural plant means that the yield of a product of the respective plant is increased by a measurable amount over the yield of the same product of the plant produced under the same conditions, but without the application of the mixture according to the invention.
Increased yield can be characterized, among others, by the following improved proper-ties of the plant: increased plant, weight, increased plant height, increased biomass such as higher overall fresh weight (FW), increased number of flowers per plant, higher grain yield, more tillers or side shoots (branches), larger leaves, increased shoot growth, increased protein content, increased oil content, increased starch content, increased pigment content, increased leaf are index. According to the present invention, the yield is increased by at least 4 %, preferable by 5 to 10 %, more preferable by 10 to 20 %, or even 20 to 30 % compared to the untreated control plants or plants treated with pesticides in a way different from the method according to the present invention. In general, the yield increase may even be higher.
A further indicator for the condition of the plant is the plant vigor. The plant vigor becomes manifest in several aspects such as the general visual appearance. In another especially preferred embodiment of the invention, the plant vigor of the treated plant is increased. In another preferred embodiment of the invention, the plant vigor of the plants treated according to the method of the invention is increased synergistically, especially in terms of imparting greening effect to crops and plants. Improved plant vigor can be characterized, among others, by the following improved properties of the plant: improved vitality of the plant, improved plant growth, improved plant development, improved visual appearance, improved plant stand (less plant verse/lodging), improved emergence, enhanced root growth and/or more developed root system, enhanced nodulation, in particular rhizobial nodulation, bigger leaf blade, bigger size, increased plant weight, increased plant height, increased tiller number, increased number of side shoots, increased number of flowers per plant, increased shoot growth, increased root growth (extensive root system), increased yield when grown on poor soils or unfavorable climate, enhanced photosynthetic activity (e.g. based on increased stomatal conductance and/or increased CO2 assimilation rate), increased stomatal conductance, increased CO2 assimilation rate, enhanced pigment content (e.g. chlorophyll content), earlier flowering, earlier fruiting, earlier and improved germination, earlier grain maturity, improved self-defence mechanisms, improved stress tolerance and resistance of the plants against biotic and abiotic stress factors such as fungi, bacteria, viruses, insects, heat stress, cold stress, drought stress, UV stress and/or salt stress, less non-productive tillers, less dead basal leaves, less input needed (such as fertilizers or water), greener leaves, complete maturation under shortened vegetation periods, less fertilizers needed, less seeds needed, easier harvesting, faster and more uniform ripening, longer shelf-life, longer panicles, delay of senescence, stronger and/or more productive tillers, better extractability of ingredients, improved quality of seeds (for being seeded in the following seasons for seed production), better nitrogen uptake, improved reproduction, reduced production of ethylene and/or the inhibition of its reception by the plant.
The improvement of the plant vigor according to the present invention particularly means that the improvement of any one or several or all of the above-mentioned plant characteristics are improved independently of the pesticidal action of the mixture or active ingredients (components).
Another indicator for the condition of the plant is the "quality" of a plant and/or its products.
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.
According to the present invention, enhanced quality means that certain plant characteristics such as the content or composition of certain ingredients are increased or improved by a measurable or noticeable amount over the same factor of the plant produced under the same conditions, but without the application of the mixtures of the present invention. Enhanced quality can be characterized, among others, by following improved properties of the plant or its product: increased nutrient content, increased protein content, increased content of fatty acids, increased metabolite content, increased carotenoid content, increased sugar content, increased amount of essential amino acids, improved nutrient composition, improved protein composition, improved composition of fatty acids, improved metabolite composition, improved carotenoid composition, improved sugar composition, improved amino acids composition, improved or optimal fruit color, improved leaf color, higher storage capacity, higher processability of the harvested products.
Another indicator for the condition of the plant is the plant's tolerance or resistance to biotic and/or abiotic stress factors. Biotic and abiotic stress, especially over longer terms, can have harmful effects on plants. Biotic stress is caused by living organisms while abiotic stress is caused for example by environmental extremes. According to the present invention, "enhanced tolerance or resistance to biotic and/or abiotic stress factors" means (1.) that certain negative factors caused by biotic and/or abiotic stress are diminished in a measurable or noticeable amount as compared to plants exposed to the same conditions, but without being treated with a mixture according to the invention and (2.) that the negative effects are not diminished by a direct action of the mixture according to the invention on the stress factors, e.g. by its fungicidal or insecticidal action which directly destroys the microorganisms or pests, but rather by a stimulation of the plants' own defensive reactions against said stress factors.

The present inventors believe that the combination of the present invention surprisingly results in a synergistic action. The combination of the present invention allows for a broad spectrum of pest control and has surprisingly improved plant vigour and yield. The broad spectrum of the present combination also provides a solution for preventing the development of resistance.
The composition of the present invention in addition to bioactive amounts of active ingredients, further comprises inactive excipients including but not limited to dispersant, anti-freezing agent, anti-foam agent, wetting agent, suspension aid, antimicrobial agent, thickener, quick coating agent or sticking agents (also referred to as “stickers” or “binders”) and buffering agent, carrier, binder, disintegrant, pH adjuster, preservative and/or coloring agent.
Surfactants that are used as dispersants have the ability to adsorb strongly onto a particle surface and provide a charged or stearic barrier to re-aggregation of particles. A dispersant is a substance which adsorbs onto the surface of particles and helps to preserve the state of dispersion of the particles and prevents them from re-aggregating. Dispersants are added to agrochemical formulations to facilitate dispersion and suspension during manufacture, and to ensure the particles re-disperse into water in a spray tank. They are widely used in wettable powders, suspension concentrates and water-dispersible granules. Surfactants that are used as dispersants have the ability to adsorb strongly onto a particle surface and provide a charged or steric barrier to reaggregation of particles. The most commonly used surfactants are anionic, non-ionic, or mixtures of the two types. For wettable powder formulations, the most common dispersants are sodium lingo sulphonates. For suspension concentrates, very good adsorption and stabilization are obtained using polyelectrolytes, such as sodium naphthalene sulphonate formaldehyde condensates. Tristyrylphenolethoxylate phosphate esters are also used. Nonionics such as alkyl aryl ethylene oxide condensates and EO-PO block copolymers are sometimes combined with anionics as dispersants for suspension concentrates. In recent years, new types of very high molecular weight polymeric surfactants have been developed as dispersants. These have very long hydrophobic ‘backbones’ and a large number of ethylene oxide chains forming the ‘teeth’ of a ‘comb’ surfactant. These high molecular weight polymers can give very good long-term stability to suspension concentrates because the hydrophobic backbones have many anchoring points onto the particle surfaces. Examples of dispersants used herein include but not limited to sodium lignosulphonates; Polyarylphenyl ether phosphate, tristyryl phenol ethylated /Acrylic Copolymer/ Ethoxylated Tristryl phenol Sulphate, Naphthalene sulfonic acid,sodium salt condensate with formaldehyde,Ethoxylated oleyl cetyl alcohol, Polyalkelene glycol ether, Ethoxylated Fatty alcohol; EO-PO block copolymers; and graft copolymers or mixtures thereof.
In one embodiment of the present invention, surfactants/dispersing agents are present in the range of 0.5-10% of the total composition.
Emulsifiers are added to buffering agent as used herein is selected from group consisting of calcium hydroxyapatite, Potassium Dihydrogen Phosphate, Sodium Hydroxide, carbonated apatite, calcium carbonate, sodium bicarbonate, tricalcium phosphate, calcium phosphates, carbonated calcium phosphates, amine monomers, lactate dehydrogenase and magnesium hydroxide.
Anti-freezing agent as used herein can be selected from the group consisting of polyethylene glycols, Mono ethylene glycol, methoxypolyethylene glycols, glycol, propylene glycol, polypropylene glycols, polybutylene glycols, glycerin, ethylene glycol, Diethylene glycol and mixtures thereof.
In one embodiment of the present invention, Anti-freezing agents are present in the range of 0.1-10% of the total composition.
Water-based formulations often cause foam during mixing operations in production. In order to reduce the tendency to foam, anti-foam agents are often added either during the production stage or before filling into bottles. Generally, there are two types of anti-foam agents, namely silicones and non-silicones. Silicones are usually aqueous emulsions of dimethyl polysiloxane while the nonsilicone anti-foam agents are water-insoluble oils, such as octanol and nonanol, or silica. In both cases, the function of the anti-foam agent is to displace the surfactant from the air-water interface.
A wetting agent is a substance that when added to a liquid increases the spreading or penetration power of the liquid by reducing the interfacial tension between the liquid and the surface on which it is spreading. Wetting agents are used for two main functions in agrochemical formulations: during processing and manufacture to increase the rate of wetting of powders in water to make concentrates for soluble liquids or suspension concentrates; and during mixing of a product with water in a spray tank or other vessel to reduce the wetting time of wettable powders and to improve the penetration of water into water-dispersible granules. Examples of wetting agents used in wettable powder, suspension concentrate, and water-dispersible granule formulations include but not limited to sodium lauryl sulphate; sodium dioctylsulphosuccinate; Tristyrylphenol ethoxylate, non-ionic emulsifier/ mixture of non-ionic surfactants & Alkoxylated Alcohol/Block copolymer, alkyl phenol ethoxylates; and aliphatic alcohol ethoxylates, their salts and mixtures thereof.
In one embodiment of the present invention, wetting agents are present in the range of 0.5-10% of the total composition.
Suspension aid in the present description denotes a natural or synthetic, organic or inorganic material with which the active substance is combined in order to facilitate its application to the plant, to the seeds or to the soil. This carrier is hence generally inert, and it must be agriculturally acceptable, in particular to the plant being treated. The carrier may be solid (clays, natural or synthetic silicates, silica, resins, waxes, solid fertilizers, and the like or mixtures thereof) or liquid (water, alcohols, ketones, petroleum fractions, aromatic or paraffinic hydrocarbons, chlorinated hydrocarbons, liquefied gases, and the like or mixtures thereof).
Biocides / Microorganisms cause spoilage of formulated products. Therefore, antimicrobial/anti-bacterial agents are used to eliminate or reduce their effect. Examples of such agents include, but are not limited to: group consisting of propionic acid and its sodium salt; sorbic acid and its sodium or potassium salts; benzoic acid and its sodium salt; hydroxy benzoic acid sodium salt; methyl p-hydroxy benzoate; and biocide such as sodium benzoate, Sodium o-phenylphenate, 5-chloro-2-methyl-4-isothiazolin-3-one, 2-methyl-4-isothiazolin-3-one 1,2-benzisothiazoline-3-one, potassium sorbate, parahydroxy benzoates, Benzisothiazolin-3-one / Formaldehyde or mixtures thereof.
In one embodiment of the present invention, antimicrobial/anti-bacterial agents are present in the range of 0.01-1% of the total composition.
Thickeners or gelling agents are used mainly in the formulation of suspension concentrates, emulsions and suspo-emulsions to modify the rheology or flow properties of the liquid and to prevent separation and settling of the dispersed particles or droplets. Thickening, gelling, and anti-settling agents generally fall into two categories, namely water-insoluble particulates and water-soluble polymers. It is possible to produce suspension concentrate formulations using clays and silicas. Examples of these types of materials, include, but are limited to, montmorillonite, bentonite clay; magnesium aluminum silicate; and attapulgite. Water soluble polysaccharides have been used as thickening-gelling agents for many years. The types of polysaccharides most commonly used are natural extracts of seeds and seaweeds are synthetic derivatives of cellulose or mixtures thereof. Examples of these types of materials include, but are not limited to; guar gum; locust bean gum; carrageenam; xanthan gum; alginates; polysaccharides, methyl cellulose; sodium carboxymethyl cellulose (SCMC); hydroxyethyl cellulose (HEC), bentonite clay, modified starches, polyacrylates, polyvinyl alcohol and polyethylene oxide or mixtures thereof Other types of anti-settling agents are based on modified starches, polyacrylates, polyvinyl alcohol and polyethylene oxide or mixtures.
In one embodiment of the present invention, thickeners or gelling agents are present in the range of 0.01-3% of the total composition.
Defoamer/Antifoaming agent are used in agro-chemical formulations to prevent foaming during mixing and spraying stage and generally added to the composition as foam formation prevents the efficient filling of a container. Antifoaming agent are selected form the group consisting of silicon emulsion based anti-foam agents, Siloxane polyalkyleneoxide, trisiloxane ethoxylates and mixtures thereof. Antifoaming agents for the composition of present invention are selected from silicon emulsion based anti-foam agents, Siloxane polyalkyleneoxide, trisiloxane ethoxylates and mixtures thereof.
In one embodiment of the present invention, antifoaming agents are present in the range of 0.01-1% of the total composition.
Filler is added to the composition to improve the handling and storage characteristics of the composition. Fillers also add mass and/or volume to the active ingredient in order to facilitate precise measurement of the doses. Suitable fillers that may be used in the composition of the present invention include, but not limited to, Silicon Dioxide, bentonite clay, china clay, silica, kaolin, talc, starch and diatomaceous earth and mixtures thereof.
In one embodiment of the present invention, fillers are present in the range of 0.1-5% of the total composition.
An adjuvant used in the present invention is any material that is added to an agrochemical formulation to enhance or modify the performance of the formulation. An adjuvant used in the present invention to make it a safer to ecological environmental, having low toxicity and having no phytotoxicity effects on any part of the plant.
Extender or sticker/sticking agent keeps pesticide active on a target for an extended period or on waxy foliage. Sticker allows pesticides to stay on a treated surface longer. Some stickers help to hold solid particles to a treated surfaces. This reduces the amount that washes off due to rain or irrigation. Others reduce evaporation and/or slow breakdown by sunlight.
Spreader allows a pesticide to form a uniform layer over a treated surface. Spreaders such as Silicone Ethoxylated Oil lowers the surface tension of spray solutions beyond that which is achievable with conventional non-ionic surfactants. In fact, it has the potential to provide adequate coverage in many low volume spray applications at rates between 0.025% and 0.1%. It decreases the surface tension of spray solutions to much lower values, in comparison to conventional adjuvants. This results in significantly enhanced spreading of spray solutions over the treated plant surfaces which carries tank mix products to morphologically complex and thus difficult-to-reach parts of the plant.

Bio-efficacy studies
Evaluation of bio-efficacy of the synergistic insecticidal composition of the present invention against Brown Plant Hoppers (BPH) (Nilaparvata lugens) in Paddy and effect in terms of phytotoxicity:
A synergistic effect exists wherever the action of a combination of active ingredient is greater than the sum of the action of each of the components alone. Therefore, in the present context, a synergistically effective amount or an effective amount of a synergistic composition or combination is an amount that exhibits greater insecticidal activity than the sum of the insecticidal activities of the individual components.
In the field of agriculture, it is often understood that the term “synergy” is as defined by Colby S.R. The action expected for a given combination of two active components can be calculated as follows:
Where E = Expected % control by mixture of three products A, B and C in a defined dose
X = Observed % control by product A
Y = Observed % control by product B
Z = Observed % control by product C
Ratio of O/E > 1, means synergism observed.
In the Colby method, the expected (or predicted) response of a combination of pesticides/insecticides is calculated by taking the product of the observed response for each individual component of the combination when applied alone divided by 100 and subtracting this value from the sum of the observed response for each component when applied alone. An unexpected enhancement in efficacy of the combination is then determined by comparing the observed response of the combination to the expected (or predicted) response as calculated from the observed response of each individual component alone. If the observed response of the combination is greater than the expected (or predicted) response, or stated conversely, if the difference between the observed and expected response is greater than zero, then the combination is said to be synergistic or unexpectedly effective, (Colby, S. R,: 25 Weeds, 1967(15), p. 20-22}. The Colby method requires only a single dose of each pesticide/insecticide applied alone and the mixture of both doses. The formula used to calculate the expected efficacy (EE) which was compared with the observed efficacy (OE) to determine the efficacy of the present invention is explained herein below.
Test Suspensions comprising a single active ingredient are sprayed to demonstrate the control efficacy of the active ingredient individually. To demonstrate the control efficacy of a combination:
a) the active ingredients can be combined in the appropriate amounts in a single test Suspension;
b) stock solutions of individual active ingredients can be prepared and then combined in the appropriate ratio, and diluted to the final desired concentration to form a test Suspension or
c) test Suspensions comprising single active ingredients can be sprayed sequentially in the desired ratio.
MATERIALS AND METHODS
Field experiment on Bio-efficacy and phytotoxicity to Rice crop
The field experiment was conducted on Rice crop in Nalgonda, Talengana during 2018-19 and 2019-20 and the experimental details as below:
Crop & Variety: Rice. Variety: BPT-5204
RBD Experimental design with 3 Replications -
No. of Treatments: 32 including Control plot
Treatment Plot size in Corn field.: 8X5 M
Application Time: Treatment were started based on the ETL level of (brown plant hopper) BPH in the field selected which coincides with first spray on 60 DAT followed by second and third sprays at 70 and 80 DAT respectively.
Observations: Pre- treatment count (PTC) of BPH and then 1, 3, 5, 7 & 10 Days after each spray was recorded from 20 hills per treatment. Average pf 3 replication was calculated for further analysis.
Spray Volume: 500 litre water per hectare
Application Equipment: Hand operated Knapsack sprayer fitted with Flat fan nozzle.
Experimental Methodology: Paddy crop was raised as per the standard agronomic practices in the field to conduct a trial to assess phytotoxicity of different inventive synergistic mixtures as tank mixture as well ready to use ternary mixture of insecticides. The trial was laid out in Randomized Block Design (RBD) with 32 treatments including untreated check (UTC), replicated three times. For each treatment plot size of 40 sq. mt was maintained. The application of different treatments with prescribed doses was done with manually operated knapsack sprayer fitted with flat fan nozzle. The spray volume was used at 500 l/h for spraying. The Untreated check plot was sprayed with water alone. Observations on phytotoxicity viz., yellowing, stunting, epinasty and hyponasty was recorded at 0,1,3,5,7 & 10 days after spraying, by adopting 0-10 rating scale as below:
0= No phytotoxicity, 1 =1-10%, 2=11-20%, 3=21-30%, 4=31-40%, 5=41-50%, 6=51-60%, 7=61-70%, 8=71-80%, 9=81-90% and 10=91-100% phytotoxicity
Percent phytotoxicity was calculated by following formula:

The results of the field trial on crop phytotoxicity presented in Table 6 indicates that the inventive composition of present invention did not cause any significant visible damage to the paddy crop in terms of loss of pigmentation, crop growth, crop vigour etc.
Thus, the synergistic insecticidal composition of the present invention gave good control of insects along with increase in yield and better economics to farmers as compared to the reference products. Further, the use of the synergistic insecticidal composition resulted in better crop condition, i.e., fresh green leaves and did not produce any phytotoxic symptoms on the plants. Also, similar trends were observed for the inventive composition of Nitenpyram + Pymetrozine + Fipronil in terms of the aforementioned and demonstrated effect of no phytotoxicity.
