Embodiments of the present invention generally relate to the field of pesticidal formulation, and, more particularly, to pesticidal emulsifiable 5 concentrate formulations comprising an effective amount of insecticide and fungicide, along with corresponding methods of uses and applications thereof.

BACKGROUND OF THE INVENTION

Pesticides are substances that are meant to control pests (Insects, 10 Diseases or Weeds). The Food and Agriculture Organization (FAO) has defined pesticide as: any substance or mixture of substances intended for preventing, curating, controlling or destroying any pest, including vectors of human or animal disease, unwanted species of plants or animals, causing harm during or otherwise interfering with the production, processing, 15 storage, transport, or marketing of food, agricultural commodities, wood and wood products or animal feedstuffs, or substances that may be administered to animals for the control of insects, arachnids, or other pests in or on their bodies. The term includes substances intended for use as a plant growth regulator, defoliant, desiccant, or agent for thinning fruit or 0 preventing the premature fall of fruit. Also used as substances applied to crops either before or after harvest to protect the commodity from deterioration during storage and transport.

Insecticides are agents of chemical or biological origin that control insects. Control may result from killing the insect or otherwise preventing it from 5 engaging in behaviors deemed destructive. Insecticides may be natural or manmade and are applied to target pests in a myriad of formulations and delivery systems. The science of biotechnology has, in recent years, even incorporated bacterial genes coding for insecticidal proteins into various crop plants that deal death to unsuspecting pests that feed on them.

0 The primary benefits are the consequences of the pesticides' effects - the direct gains expected from their use and it must be safe to the soil and has very little negative impact on natural beneficial predators, parasites and pollinator such as coccinellids, spiders, egg parasitoids and mirid bugs. Fauna of natural enemies in different Rice ecosystems are known to occur in families Carabidae, Coccinellidae, Cicindelidae, Staphylinidae, 5 Geocoridae, Miridae, Libellulidae, Coenagrionidae, Empusidae, Mantodae, Sciomyzidae, Syrphidae, Platystomatidae, Ephydridae, Ascalaphidae, Dermistidae, lchneumonidae, Braconidae, Mutillidae, Lycosidae, Oxyopidae and Tetragnathidae (Parasappa H. H et al. ,“Rice insect pests and their natural enemies complex in different Rice ecosystem of Cauvery 10 command areas of Karnataka’’ Journal of Entomology and Zoology Studies 2017; 5(5): 335-338).

Pests such as Yellow stem borer, Whorl maggot, Brown planthopper, Green leafhopper, Thrips, Magnaporthe oryzae, Alternaria porri, Alternaria alternate and Podosphaera xanthii causes serious damages to plants, such 15 as Paddy, Onion, Garlic, leeks, Chilies, Capsicum, Celery, Peas, Melon, Choy sum, Bitter melon, Chinese Broccoli, Long Melon, Snake Bean and Pod vegetables.

Paddy becomes Rice after the removal of husk by threshing. Therefore, Rice is a part of paddy, hence paddy is the Rice grain with husk. The term 0 paddy was derived from Malay word with the meaning of“Rice in the straw or husk”. Generally, Rice plant also is called paddy. This is a crop which belongs to the family Graminae. Botanical name of the paddy is Oryza sativa. It is a traditional wetland crop but in recent times upland /dryland crop is in practice, which extensively grows all over the worlds.

5 Rice is a major food crop for the people of the world in general and Asians in particular; nearly 90% of the world's Rice is produced and consumed in this region. The other major producers of Rice are South and Central America and Africa. In South and Central America, Rice production is scattered throughout the region.

0 India is one of the world's largest producers of Rice and brown Rice, accounting for 20% of all world Rice production. Rice is India's pre-eminent crop, and is the staple food of the people of the eastern and southern parts of the country. Rice is one of the chief grains of India. Moreover, this country has the largest area under Rice cultivation, as it is one of the principal food crops. It is in fact the dominant crop of the country. India is one of the leading producers of this crop. Rice is the basic food crop and being a tropical plant, it 5 flourishes comfortably in hot and humid climate. Rice is mainly grown in rain fed areas that receive heavy annual rainfall.

It demands temperature of around 25 degree Celsius and above and rainfall of more than 100 cm. Rice is also grown through irrigation in those areas that receives comparatively less rainfall. Rice is the staple food of eastern 10 and southern parts of India.

The regions cultivating this crop in India is distinguished as the western coastal strip, the eastern coastal strip, covering all the primary deltas, Assam plains and surrounding low hills, foothills and Terai region- along the Himalayas and states like West Bengal, Bihar, eastern Uttar 15 Pradesh, eastern Madhya Pradesh, northern Andhra Pradesh and Odisha.

India, being a land of eternal growing season, and the deltas of Kaveri River, Krishna River, Godavari River, Indravati River and Mahanadi River with a thick set-up of canal irrigation like Hirakud Dam and Indravati Dam, permits farmers to raise two, and in some pockets, even three crops 0 a year. Irrigation has made even three crops a year possible. Irrigation has made it feasible even for Punjab and Haryana, known for their baked climate, to grow Rice. They even export their excess to other states. Punjab and Haryana grow prized Rice for export purposes. Kaveri delta region of Thanjavur is historically known as the Rice bowl of Tamil Nadu 5 and Kuttanadu is called the Rice bowl of Kerala.

The agricultural GDP rises after the Kharif harvest, but declines in the next nine months. After the harvest of Rabi crops, the value of agricultural output declines by almost one-fifth, despite a good Kharif.

Rice has maintained a positive growth in yield, while it is negative for wheat. 0 So, if the agricultural GDP has to grow, it would seem that Rice output needs to grow even faster than it is at present. Rice, it does seem, is more important for India’s GDP. Similarly, onion crop is also affected by insects and diseases which result in the less production of onion. Biggest producers of onion are China, India and the USA. These countries produce around half of the world’s dry onions. Other countries, with annual production above 1 million tonnes, are Brazil, 5 Iran, Japan, Pakistan, Turkey and Russia. India is the second largest onion growing country in the world. Indian onions are famous for their pungency and are available round the year. Indian onions has two crop cycles, first harvesting starts in November to January and the second harvesting from January to May.

10 There is a lot of demand of Indian Onion in the world, the country has exported 24, 15,757.11 MT of fresh onion to the world for the worth of Rs. 3,106.50 crores/ 464.02 USD Millions during the year 2016-17.

Modern pack houses for sorting, grading and packing of the quality onions are available at production zones. Guidelines has been framed to determine 15 the compliance with maximum residue levels (MRLs) for the identified pesticides and Grade designation and quality development parameters has been set up. The major varieties found in India are Agrifound Dark Red, Agrifound Light Red, NHRDF Red, Agrifound White, Agrifound Rose and Agrifound Red, Pusa Ratnar, Pusa Red, Pusa White Round. There are 0 certain varieties in yellow onion which are suitable for export in European countries Tana F 1 , Arad-H, Suprex, Granex 55, HA 60 and Granex 429. The Major Onion producing states in India are Maharashtra, Karnataka, Madhya Pradesh, Gujarat, Bihar, Andhra Pradesh, Rajasthan, Haryana and Telangana. Maharashtra ranks first in Onion production with a share of 5 28.32%.

Pod vegetables are a type of fruit vegetables where pods are eaten, much of the time as they are still green. There are different categories of pod vegetable such as Bean, Black turtle bean, Edamame, Flat bean, Green bean, Okra, Raphanus caudatus, Snap pea, Snow pea and Winged bean. 0 These vegetables provides adequate amounts of essential nutrients like vitamins, minerals and dietary fiber. Some of these vegetables such as pea pods, okra are dense with these nutrients, as well as being low-calorie, low- fat and cholesterol-free which give human diet a boost of nutrition. Pests such as Yellow stem borer, Whorl maggot, Brown planthopper, Green leafhopper, Thrips, Magnaporthe oryzae, Alternaria porri, Alternaria alternate and Podosphaera xanthii causes serious damages to plants. If thrips population is high the leaves of plant may be distorted. Leaves are 5 covered in coarse stippling and may appear silvery and speckled with black feces. This insect is small (1.5 mm) and slender and best viewed using a hand lens. Adult thrips are pale yellow to light brown and the nymphs are smaller and lighter in color. Mostly powdery mildew is the major cause of low yield and loss for Pod vegetables.

10 Therefore, there is a need to protect Paddy, Onion, Garlic, leeks, Chilies, Capsicum, Celery, Peas, Melon, Choy sum, Bitter melon, Chinese Broccoli, Long Melon, Snake Bean and Pod vegetables from effects of insects and disease.

Major insects and diseases

15 The Rice when affected by insects like whorl maggot, yellow stem borer, brown plant hopper, green leaf hopper, and also diseases viz, Leaf blast disease, panicle blast and Neck blast disease, reduces the crop yield and thus country's Rice production get declined.

Standing water in Paddy during the vegetative stage, presence of host 0 plants year-round, and transplanting of young seedlings favor the development of Rice whorl maggot.

The Rice whorl maggot is semi-aquatic. It is common in irrigated fields and feeds on the central whorl leaf of the vegetative stage of the Rice plant. It does not occur in upland Rice. It also prefers ponds, streams and lakes or 5 places with abundant calm water and lush vegetation.

The insect does not prefer direct-seeded fields and seedbeds. The adult is active during the day and rests on Rice leaves near the water. It floats on the water or perches on floating vegetation. At midday, it is sedentary or it clings on upright vegetation. It prefers thick vegetation and is attracted to 0 open standing water around seedbeds. Neonate maggots feed on the unopened central leaves where larval development is completed in 10-12 days. The full-grown maggots pupate outside the feeding stalk. The feeding damage of whorl maggots causes yellow spots, white or transparent patches, and pinholes.

The larva uses its hardened mouth hooks to rasp the tissues of unopened leaves or the growing points of the developing leaves. The damage 5 becomes visible when the leaves grow old. Mature larva prefers to feed on the developing leaves of the new developing tillers at the base of the Rice plant.

The stem borer larvae bore at the base of the plants during the vegetative stage. On older plants, they bore through the upper nodes and feed toward 10 the base.

The yellow stem borer is an insect of deepwater Rice. It is found in aquatic environments where there is continuous flooding. Second instar larvae enclose themselves in body leaf wrappings to make tubes and detach themselves from the leaf and falls onto the water surface. They attach 15 themselves to the tiller and bore into the stem.

Stem borers can destroy Rice at any stage of the plant from seedling to maturity.

They feed upon tillers and causes deadhearts or drying of the central tiller, during vegetative stage; and causes whiteheads at reproductive stage. 0 Two species of planthopper infest Rice. These are the brown planthopper (BPH), Nilaparvata lugens (Stal); and the whitebacked planthopper (WBPH), Sogatella furcifera (Horvath).

Planthoppers can be a problem in rainfed and in irrigated wetland environments. It also occurs in areas with continuous submerged conditions 5 in the field, high shade, and humidity.

Closed canopy of the Rice plants, densely seeded crops, excessive use of nitrogen, and early season insecticide spraying also favors insect development.

High population of planthoppers cause leaves to initially turn orange-yellow 0 before becoming brown and dry and this is a condition called hopperburn that kills the plant.

BPH can also transmit Rice Ragged Stunt and Rice Grassy Stunt diseases. Neither disease can be cured. Two species of green leafhoppers (GLH) can spread tungro: Nephotettix malayanus and Nephotettix virescens.

Green leafhoppers are common in rainfed and irrigated wetland environments. They are not prevalent in upland Rice. Both the nymphs and 5 adults feed on the dorsal surface of the leaf blades rather than the ventral surface. They prefer to feed on the lateral leaves rather than the leaf sheaths and the middle leaves. They also prefer Rice plants that have been fertilized with large amount of nitrogen.

Blast can occur wherever blast spores are present. It occurs in areas with 10 low soil moisture, frequent and prolonged periods of rain shower, and cool temperature in the daytime. In upland Rice, large day-night temperature differences that cause dew formation on leaves and overall cooler temperatures favor the development of the disease.

Rice can have blast in all growth stages. However, leaf blast incidence tends 15 to lessen as plants mature and develop adult plant resistance to the disease.

Node and neck blast commonly occur together and have similar symptoms and when a node or neck blast infection is present, it can cause plants to develop few or no grains at all.

0 Blast is caused by the fungus Pyricularia oryzae (sexual morph Magnaporthe oryzae). It can affect all above ground parts of a Rice plant: leaf, collar, node, neck, parts of panicle, and sometimes leaf sheath.

Major insect problem of onion is Thrips which sucks the succulent leaves reducing to dry and chaffy. The significant disease problem is Purple blotch 5 caused by Alternaria porri, the initial symptoms of purple blotch are small, water-soaked lesions with white centers that appear usually on older leaves. As the disease progresses, the lesions enlarge (individual lesions can be as long as 1-2 inches) and become purplish with light yellow concentric rings on the margins. As severity increases, leaves turn yellow brown, lose 0 erectness, and wilt. Windborne conidia from previous crop debris initiate infection, which is favored by high temperatures and humid conditions. Prolonged leaf wetness increases the probability of further infection. Further, Chilli is one of the spices used to enhance the flavour and taste of cooked food. Insects like thrips and fungal diseases are the main biological constraints in chilli production, and Alternaria leaf spot disease, one of the most devastating diseases of chilli caused by the species of Alternaria 5 (Alternaria alternate).

In pod vegetables the major problem is from insect like Thrips and disease caused from species of phylum Ascomycota, especially Magnaporthe oryzae, Alternaria porri and Alternaria alternate and Podosphaera xanthii. Here phylum is a level of classification or taxonomic rank below Kingdom 10 and above Class having a group of organisms with a certain degree of morphological or developmental similarity.

Powdery mildew is a fungal disease that affects a wide range of plants. Infected plants display white powdery spots on the leaves and stems. The lower leaves are the most affected, but the mildew can appear on any 15 above-ground part of the plant. As the disease progresses, the spots get larger and denser as large numbers of asexual spores are formed, and the mildew may spread up and down the length of the plant. This fungal disease is caused by Podosphaera xanthii.

Thrips cause direct damage by using their piercing and sucking mouthparts 0 to pierce plant cells and suck the cell contents, which results in the deformation of flowers, leaves, stems, shoots, and fruits. Damage appears as silvering and flecking on the leaves of seedlings. Severe infestations can result in bronzing, yellowing and stunting of leaves. Thrips can also damage buds and flowers through laying eggs, causing deformed fruit to develop. 5 The fungal disease caused by Alternaria result in the serious damages to plant leaves and fruits which reduce the final yield from field.

Previously people have tried many alternatives and option to overcome the problem of insects and disease. For managing the disease effectively in Onion, people are doing crop rotation of 2-3 years with non-related crops. 0 Further, formulations like Mancozeb @ 0.25% or Chlorothalonil @ 0.2% or Rovral @ 0.25% are sprayed at fortnightly interval commencing from one month after transplanting. For managing the disease effectively in Rice (Paddy), farmer are using Fipronil Granule Chloropyriphos, Carbofuran, Cartap hydrochloride (GR), Lamda cyhalothrin and Fipronil SC formulation in order to control Stem borer and leaf folder. This will be followed by the application of 5 Isoprothiolane for the control of Blast and Buprofenzin for controlling BPH.

With regards to management of Alternaria diseases of chili, lowest per cent disease index was observed in combination spray of Propiconazole (Tilt 25% EC) @ 0.05% + Eucalyptus spp. @ 10% + Pseudomonas fluorescens @ 5g/ liter which was followed by spray with Propiconazole (Tilt 25% EC) 10 @ 0.05% + P. fluorescens@ 5g/ liter.

For vegetables to control thrips and disease caused by Alternaria species people does application of neem cake (once immediately after germination and again at flowering) in soil followed by NSPE @ 4% and neem soap 1 % alternately at 10-15 days interval. They spray any systemic insecticides like 15 Acephate 75 SP @ lg/1 or Dimethoate 30 EC @ 2ml/l or one foliar spray of Chlorothalonil @ 0.2% alternated by thiophenate-methyl@ 0.1 % after 8-10 day.

So, there was the need of formulation having the widened spectrum of action on the insect and disease in tandem. The present invention of a 0 pesticidal emulsifiable concentrate formulation provides the best control against pest and disease like Yellow stem borer, Whorl maggot, Brown planthopper, Green leafhopper, Thrips, Magnaporthe oryzae, Podosphaera xanthii, Alternaria species like Alternaria porri and Alternaria alternata. Fipronil is a broad-spectrum insecticide that belongs to the phenylpyrazole 5 chemical family. Fipronil disrupts the insect central nervous system by blocking GABA-gated chloride channels and glutamate-gated chloride (GluCI) channels. This causes hyperexcitation of contaminated insects' nerves and muscles. Fipronil's specificity towards insects is believed to be due to its greater affinity to the GABA receptor in insects relative to 0 mammals and its effect on GluCI channels, which do not exist in mammals.

It is chemically known as (RS)-5-Amino-1-[2, 6-dichloro-4-(trifluoromethyl) phenyl]-4-(trifluoromethylsulfinyl) pyrazole-3-carbonitrile and having chemical structure formula represented as below,

Fipronil

Because of its effectiveness on a wide range of insects, Fipronil is used as

5 the active ingredient in flea control products for pets and home roach traps as well as field pest control for corn, golf courses, and commercial turf. Its widespread use makes its specific effects the subject of considerable attention. This includes ongoing observations on possible off-target harm to humans or ecosystems as well as the monitoring of resistance

10 development. Fipronil was discovered and developed by Rhone- Poulenc between 1985 and 1987, and placed on the market in 1993 under the US Patent 5232940A.

Isoprothiolane is a systemic fungicide with curative and protective effects. Isoprothiolane is a chemical compound from the group of Dithiolanes and

15 introduced in 1974 by Nihon Noyaku as fungicide. Isoprothiolane has a conspicuous ketene- di thioacetal structure. It is chemically known as Diisopropyl 2- (1 , 3-dithiolane-2-ylidene) malonate and having chemical structure formula represented as below,

0 Isoprothiolane

The main concern of this invention is the development of effective pesticidal emulsifiable concentrate formulation, which is on one hand is effective in wider range to control insects like Thrips, Aphids, Jassids, whorl maggot, Yellow stem borer, Brown plant hopper, Green leaf hopper and diseases like leaf blast neck blast and purple blotch on one hand with ensuring environmental safety and intrinsic property of stability on another hand.

Example 3.1 : Experiment against Stem borer. Blast disease and Brown 5 Plant Hopper (BPH) in Rice (Paddy)

Rice is regarded as one of the most important staple crop of our nation. India Ranks Second after China in Rice production. The crop is affected by various diseases and insects that cause a considerable loss in food grain production and is one of the main challenges that needs to be addressed to, in order to attain food security for the nation. The current pesticide usage in Rice is that of multiple spraying as per the pest prevalence. In this context 5 pesticidal emulsifiable concentrate comprising Fipronil and Isoprothiolane was tested for different windows of application and was found to give excellent control over stem borer, leaf folder, Blast and also showed prophylactic effect on BPH following its two applications. A pesticidal emulsifiable concentrate comprising Fipronil and Isoprothiolane was 10 developed at in-house R&D laboratory.

The general population dynamics of the pests

Stem borer infestation started from mid-July (30-35 DAT= Days After Treatment). Initially the infestation was very minor (around 2%). This population started building up and reached its peak (60-65 % infestation) at 15 around 45 DAT. It then took a declining trend and kept on falling towards the maturity of the crop. Leaf folder infestation up to 2%, beginning from 35- 40 days after transplanting was observed. Leaf folder showed up after Stem borer, but with a higher intensity. The population reached a peak, with 70- 75% infestation, at 50-55 DAT, it remained constant for a while and then 0 followed a declining trend. Brown plant hopper was sighted beginning from 65 days after transplanting with an infestation of 50%. The population reached its peak (80 -90% infestation) in 75 to 80 DAT. Hopper burn was also observed due to severe pest density. The population then followed a declining trend similar to the other pests. Very few plants (1 or 2/metre ² ) 5 showed the symptoms of blast initially but latter the disease did not spread further due to non-conducive environment and good plant vigor. It was recorded that in the hierarchy of appearance, Stem borer was first followed by leaf folder and Brown Plant Hopper respectively, however the pest with the maximum intensity was BPH, followed by Leaf folder and Stem borer 0 respectively. Considering the standard package of practices, normally a farmer will go for Fipronil SC, Fipronil Granule, Chlopropyrifos, Cartap hydrochloride (GR), Lamda cyhalothrin and Fipronil SC formulation in order to control Stem borer and leaf folder. Subsequently, Isoprothiolane and Buprofezin are used to control Blast and BPH respectively.

In light of the above stated facts a trial was conducted at Research Farm Ambala in the state of Haryana, to assess the bio efficacy of pesticidal 5 emulsifiable concentrate comprising Fipronil and Isoprothiolane was done against the major insect of Rice with special reference to Stem borer, Leaf folder, Brown plant hopper and disease like Rice blast. Filed trials were laid out in a randomized block design with nine treatments, replicated thRice. Rice variety PUSA BASMATI 1121 (135 days duration) susceptible to 10 different insect pest and disease was planted at a spacing of 15 ^c 15 cm.

The sprays were carried out as per the treatments, using a battery operated knapsack sprayer (15 lit capacity). 200 lit water per Acre was used for conducting the spray. The observations were taken 3, 5, 7 and 15 days after the spray.

Example 3.2: Experiment against Thrips and Purple blotch disease in Onion

5

Purple Blotch is caused by the fungus Alternaria porri. It is an important disease in warm, humid onion-growing regions around the world. Garlic and leeks also get affected by purple blotch. And on another hand Thrips, order Thysanoptera, are tiny, slender insects with fringed wings. They feed by 10 puncturing the epidermal (outer) layer of host tissue and sucking out the cell contents, which results in stippling, discolored flecking, or silvering of the leaf surface. Thrips feeding is usually accompanied by black varnish like flecks of frass (excrement). Specie Onion thrips (Thrips tabaci) cause damage to Onion, Garlic, leeks, Chilies, Capsicum, Celery, Peas, Melon, Choy sum, Bitter gourd , Chinese Broccoli, Long Melon and Snake Bean. in the same manner.
