DESC:FIELD OF THE INVENTION
The present invention relates to the field of pesticides. The present invention in particular relates to a synergistic, broad spectrum insecticidal composition comprising Emamectin benzoate, Chlorantraniliprole and Deltamethrin. The present invention further relates to the process of preparation of said composition and uses thereof.
BACKGROUND OF THE INVENTION
The 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, or that any publication specifically or implicitly referenced is prior art.
Pest infestations pose significant adverse effect on economically important agricultural crops such as cotton, brinjal, okra, tomato, chilli, soybean, chick pea and cabbage. Particularly, cotton an important fiber and cash crop and chilli a spices crop which plays a dominant role in the industrial and agricultural economy are infested by major insects such as sucking insects which includes thrips, aphids, whiteflies and jassids and caterpillars such as helicoverpa, spodoptera and pink bollworm.
To address this problem, researchers are trying to produce an extensive variety of active ingredients and active ingredients formulations effective in the control of insects. Chemical insecticides of many types have been disclosed in the art and a large number are in commercial use. In crop protection, it is desirable in principle to increase specificity and reliability of action of insecticidal active ingredients.
Imidacloprid, emamectin benzoate, ethion, fenpropathrin, fipronil, dimethoate, lambda cyhalothrin, methomyl, spinosad, thiacloprid, diafenthiuron, thiamethoxam, novaluron, lufenuron are compound independently known in the art for their insecticidal potency. They are disclosed in “The Pesticide Manual” 15th Edition, published 2009 by the British Crop Protection Council, and are also commercially available.
WO 2000/002453 A1 generically enables the combination of Phenthoate and Emamectin benzoate emulsifiable concentrates formulation comprising use of surfactants, and an aromatic solvent.
However, certain insect pests are becoming more and more resistant to a number of most widely used insecticides available in the art. Thus, on one hand even more stringent conditions are being placed on the type and use rate of insecticide, while on the other hand approved insecticides are becoming less and less effective over time in insect pests available in the art.
Furthermore, it is very expensive and time consuming to seek and obtain registration of a new insecticide compound, including its proposed use rate. Approval data required must not only include evidence of efficacy at the application rates proposed but also safety of insecticide when applied at the recommended level, also the recommended level of insecticide that may be applied per unit of area is under pressure from governmental, as well as for economic and environmental reasons.
Accordingly, demonstration of synergism by combination of existing insecticide agents, permits use of individual agents of synergistic combination at lower rates than when used alone, and in many instances ameliorates increasing resistance to insecticidal effectiveness.
Thus, there is a great need in the art for environmentally safe, stable, synergistic, broad-spectrum, better efficacious, insecticide composition comprising combination of three active ingredients having different mode of action, showing one or more of advantage such as stability, synergistic effect, faster onset of insecticide action, a broad-spectrum and long-lasting action reduced dosage of active ingredients, reduced application rate of the insecticide thereby rendering such combination environmentally safe, and reduce or delay the development of resistance in pests, which is necessary to obtain acceptable insect pest control and a process for preparing such insecticide composition or formulation comprising the same.

EVALUATION OF BIO-EFFICACY IN CHILLI CROP
Insect-pest population was recorded from 5 fixed plants/plot, selected randomly for this purpose. The population of thrips was recorded from 5 upper, 5 middle and 5 lower leaves of 5 randomly selected plants and averaged to get number of thrips/plant. Similarly, yellow mite population were recorded. Data was recorded as 1 day before and 5, 10 and 14 days after each spray. All the observations were recorded with the help of a hand lens (10X).
During each plucking, damaged and fresh chilli fruit were recorded and converted to percent damaged and healthy fruits per plant and present cumulative data of all plucking. Percent damaged fruits were calculated using the following formulae.
Percent fruit infestation= (Number of infested fruits)/(Total number of fruits) ? 100
The data thus obtained in different treatments were subjected to analysis of variance by using SPSS version 16.0 and significant differences among treatment means were tested with LSD at p<0.05 after necessary transformation (Gomez and Gomez, 1984). Reduction of pest population in different treatments over control was used as an indicator of insecticidal efficacy which was calculated from the following formula (Flemming & Retnakaran, 1985). Population reduction (%) =
Post-treatment population in treatment Pre-treatment population in untreated control
1- ----------------------------- x ------------------------------- x100
Pre-treatment population in treatment Post-treatment population in untreated control
b) Effect on natural enemies: The major predators namely coccinellid beetle were observed abundantly in the chilli field. For data recording, the predator populations were noted down from 5 plants randomly selected in each plot leaving the border rows just before insecticidal application as well as 5, 10 & 15 days after each spraying.
d) Record on yield: Yield of healthy marketable chilli was recorded during each picking from the selected plants in each plot and latter cumulated to calculate the yield in quintal per hectare. Mean yield estimated in different treatments was subjected to statistical analysis and compared by DMRT (Gomez and Gomez, 1984).
The per cent increase of yield in treatment over control was calculated from the following formula (Vanisree et al., 2013).
Per cent increase of yield in treatment over control =
Yield in treatment – Yield in control
---------------------------------------------- x 100
Yield in control
2. Trial condition: The field experiment was conducted during Rabi-2023-24 having sub-humid and sub-tropical climate at Agricultural farm, Palli Siksha Bhavana, Visva-Bharati, Sriniketan, Birbhum, West Bengal. The field is situated at 23.390N Latitude, 87.420F Longitude and at an average Altitude of 58.90 m above mean sea level in the Lateritic belt of West Bengal.

RESULT
During the study, the crop showed variable levels of infestation of Thrips -Scirtothrips dorsalis, Mites - Polyphagotarsonemus latus and Fruit borers - Helicoverpa armigera and Spodoptera sp.
Effect of treatments on Thrips: Scirtothrips dorsalis and Mites: Polyphagotarsonemus latus: Data presented in Table 3 revealed that, the pre-treatment population of thrips in different treatments did not differ significantly. All the insecticidal treatments significantly reduced the infestation of thrips as compared to untreated control. Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 469 ml/ha was found most efficacious among the treatments and it was on par with its lower dose Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 375 ml/ha. Similarly, mites population before the spraying did not differ significantly in the 1st season, application of Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 469 ml/ha was found most efficacious among the treatments and it was on par with its lower dose Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 375 ml/ha (Table 4).
Effect of treatments on Fruit borers: Helicoverpa armigera and Spodoptera sp: Table 5 revealed that, Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 469 ml/ha was found most efficacious among the treatments and gave the maximum fresh semi ripe chilli fruit and it was on par with Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 375 ml/ha. Percent fruit damage reduction over control was followed as Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 469 ml/ha (77.35) > Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 375 ml/ha (76.69) > Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 281.25 ml/ha (73.38) > Chlorantraniliprole 18.50 % SC @ 150 ml/ha (72.34) > Emamectin benzoate 1.9 % EC @ 375 ml/ha (70.72) > Deltamethrin 02.80 % EC @ 500 ml/ha (59.68), Dimethoate 30 % EC @ 990 ml/ha (44.23), Diafenthiuron 30 % + Pyriproxyfen 8% SC @ 1000 ml/ha (8.86), respectively.
Effect of treatments on natural enemies of chilli ecosystem: During the period of study, natural enemy fauna lady bird beetle (C. septempunctata) was observed. The application of the insecticides was not found any significantly reduction of the lady bird beetle population (Table 7).
Effect of Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC on crop health: Table 7 showed that, no phytotoxic symptoms was observed due to application of Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 750 ml/ha. in chilli crop.
Effect of treatments on Yield: The yield of healthy semi ripe chilli fruits recorded in different treatments is presented in Table 6. All the insecticidal treatments significantly increased the yield as compared to the control (42.10 q/ha). Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 469 ml/ha, gave the maximum yield (56.12 q/ha) and it was found on par with Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 375 ml/ha.
Conclusion: The above results clearly show that, the Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 375 and 469 ml/ha effectively controlled chilli thrips, mites and fruit borers and produced maximum fruit yield of chilli. Two doses of Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 375 and 469 ml/ha was safe to coccinellid natural enemies which were frequently observed on the chilli crop. The chemical even at higher doses Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 750 ml/ha not causes any kind of phytotoxicity to chilli crop. On the basis of bio-efficacy, yield, safety to natural enemies and crop safety, Emamectin benzoate 1.9 % + Chlorantraniliprole 5 % + Deltamethrin 1 % EC @ 375 and 469 ml/ha may be recommended for effective management of sucking pest complex and fruit borer of chilli. ,CLAIMS:
