DESC:FIELD OF THE INVENTION:
The present invention relates to the field of stable synergistic agrochemical composition comprising insecticides and plant growth regulator which acts as a plant growth & health promoter. More particularly, the present invention relates to a stable synergistic agrochemical composition comprising Chlorantraniliprole or its agrochemically acceptable salts, esters and derivatives in combination with pyrethroid insecticide i.e. Deltamethrin or its agrochemically acceptable salts, esters and derivatives and a plant growth regulator which acts a plant growth and health promoter i.e. Triacontanol or its agrochemically acceptable salts, esters and derivatives. The present invention further relates to a process of preparing said stable synergistic agrochemical composition along with inactive excipient (s) and formulation thereof.

BACKGROUND OF THE INVENTION:
The following background is provided for understanding the context only and is not intended to define the scope of the invention or having any relevance to the existence of the prior art for the invention disclosed forth herein.

Agriculture is back bone of Indian economy wherein > 70% population dependent on agriculture for their subsistence and their harvested produce is being used as staple food for 100% ever growing population. Crop pests & diseases causing damage to crops to the extent of > 30% of yield will be affected. Farm yields, both in terms of quality and quantity, depend on several factors such as good agronomic practices (like proper crop management), timely fertilization, and, most importantly, insect-pest’s control measures. Without appropriate insect-pest’s control measures, the farm’s overall productivity gets negatively impacted. Therefore, insect-pest’s control is crucial not only for increasing crop yield but also for improving the income of farmers on an individual level, as well as contributing to the overall economic growth (GDP) of the country. In other words, if farmers don't implement effective pest control strategies, their crop yield will suffer, affecting their income and the broader national economy.
In India, agriculture and horticulture cover about 60% of the cultivated land, contributing 19% to GDP, with 42% of the population dependent on farming. Pesticides are crucial for preventing and treating insect-pest’s issues, but to save money and reduce pesticide use, combination products are essential. Effective crop protection ensures higher yields and better-quality produce by safeguarding against harmful insect-pests. Farmers rely on insecticides, biotechnology-based products, and plant nutrition solutions to improve crop health. Since no single pesticide addresses all pest problems, therefore combining insecticides with plant growth regulators which acts as a plant growth and health promoter offers a more effective, cost-efficient approach, reducing the need for multiple applications. This integrated method supports sustainable farming practices and enhances both productivity and economic viability in agriculture. Therefore, there is a need to develop a composition that not only help save farmers valuable resources but also reduce the frequency of pesticide applications. By streamlining insect-pests control, the composition of the present invention enables more efficient use of both time and money of farmers, ultimately enhancing the sustainability and cost-effectiveness of farming practices
Chlorantraniliprole belongs to diamide class of insecticides and is a member of pyrazole group. It targets the ryanodine receptors in insect muscle cells, causing a disruption in calcium ion regulation, which leads to paralysis and death of the insect. This selective action makes it effective against a variety of pests, particularly lepidopteran larvae, while minimizing harm to beneficial organisms. It is used to protect a wide range of crops, including corn, cotton, grapes, rice, and potatoes against various insect pests such as cabbage loopers, corn borers, armyworms, cutworms etc. The structure of chlorantraniliprole is provided below:

Chlorantraniliprole
There are many prior arts available where Chlorantraniliprole is combined with other active ingredients in an agrochemical composition. In regard, reference may be made to the following:
Chinese patent application no. CN117441739 discloses combination of chlorantraniliprole and dinotefuran formulated as water dispersible granule formulation.
Further reference can be made to Chinese patent application no. CN108184859, which discloses combination of chlorantraniliprole with pyrethroid insecticide selected from cyfluthrin, beta-cypermethrin, beta-cyfluthrin or bifenthrin.

Chlorantraniliprole once a promising insecticide now identified as persistent and mobile in edaphic environments and can cause the accumulation of residue from extended use and cause damages to the ecological structure, damages vital micro- organisms which are crucial for soil health and have also developed resistance against harmful complex insect’s pests. Numerous prior arts highlighted chlorantraniliprole insecticidal activity, but practical applications revealed resistance concerns and environmental repercussions caused by its usage. During field trials and farmer consultations underscored that there is the urgent need for an improved solution that not only curtails resistance but also minimizes ecological damage to soil.

In response to these challenges, extensive research was conducted to explore alternative formulations. It was discovered that by combining Chlorantraniliprole with pyrethroid insecticide i.e. Deltamethrin and a plant growth regulator which acts a plant growth & health promoter i.e. Triacontanol overcomes the problems associated with solo compositions of Chlorantraniliprole. Thus, the inventors have arrived at a stable synergetic agrochemical composition comprising Chlorantraniliprole with pyrethroid insecticide i.e. Deltamethrin and a plant growth & health regulator i.e. Triacontanol to combat resistance and minimize ecological damage to soil and vital soil micro-organisms.

Deltamethrin chemically known as (S)-cyano(3-phenoxyphenyl)methyl (1R,3R)-3-(2,2-dibromoethenyl)-2,2-dimethylcyclopropanecarboxylate. It belongs to pyrethroid broad class of insecticides, and is a Sodium channel modulator which is found to be effective against various insects-pests including cockroaches, spiders, ants, fleas, aphids, bed bugs, mites and beetles. Its larval mortality is higher than any other pyrethroids such as Cypermethrin, Lambda cyhalothrin etc. The chemical structure of Deltamethrin is provided below:

Deltamethrin
Triacontanol is a fatty alcohol of the general formula C30H62O, also known as melissyl alcohol or myricyl alcohol. It is an endogenous plant growth regulator which facilitates numerous plant metabolic activities leading to better growth and development. It plays essential roles in alleviating the stress-accrued alterations in crop plants via modulating the activation of the stress tolerance mechanisms. Its exogenous application enhances plant biomass, photosynthetic pigments, gas exchange parameters, mineral nutrient acquisition, leaf carbonic anhydrase (CA), nitrate reductase (NR) activity, osmolytes accumulation, modulates antioxidant enzyme activities, yield and quality attributes. It also causes changes in stem, leaf anatomy and affect vascular tissue systems in plants. It has extreme role in plants response to abiotic stresses such as acid mist, chilling, drought, heavy metal and salt stress. The Chemical Structure of Triacontanol is provided below:

Triacontanol

The strategic combination of Chlorantraniliprole with Deltamethrin and Triacontanol and that too in a specific weight percentage range is synergistic, highly efficacious over known composition containing Chlorantraniliprole. The present invention offers a solution to reduce resistance in pest populations, providing benefits to improve soil ecology and promotes growth of good microbes present in soil responsible for better plant/crop health and enhanced crop yield.

The development of stable synergistic agrochemical composition is driven by several key factors that address the challenges faced by farmers in pest management. Often, crops are attacked by a variety of insect species simultaneously, and during such critical times, farmers resort to tank mixing different insecticides. Therefore, present invention which is a stable synergistic agrochemical composition offers a solution by enabling the control of multiple insect pests with a single spray. The stable synergistic agrochemical composition of the present invention provides synergistic action, offering more effective control at a lower cost, with superior efficacy. The formulation process of combining different insecticides along with plant growth & health regulator which acts as a plant growth & health promoter ensures uniformity, compatibility, stability and enhanced synergistic effects against insect-pest’s populations, even allowing for effective control of insecticide-resistant pests. This compsoition provide farmers with ready-made solutions for a wide range of insect pests at a fair price. Additionally, combining insecticides with more environmentally safer alternatives is a crucial component of developing sustainable, safe insect-pest’s control solutions.

The present invention satisfies the existing needs, as well as others, and generally overcomes the deficiencies found in the prior art.

The present invention composition is synergistic, efficacious, environmentally friendly, simple to formulate, stable, safe to use and has longer shelf life.

MANUFACTURING PROCESS: -

Xanthum gum Gel Preparation: Xanthan gum was taken in a beaker, and 1 gram of propylene glycol was added. The mixture was then made up to 100 ml with deionized water and stirred using a glass rod to create a uniform gum dispersion. The mixture was allowed to stand for 12 hours to ensure the development of a uniform solution, free from lumps. This recipe was prepared for 100 grams of finished material.
PREMIXING:
Step 1: The pre-determined quantities of de-mineralized water, poly dimethyl siloxane, acrylates copolymer, and propylene glycol were charged into a dry, clean beaker. The mixture was stirred for 10 to 15 minutes to obtain a homogeneous slurry.
Step 2: Precipitated silica and all active ingredients were gradually added to the above slurry while stirring. The contents were mixed for an additional 30 minutes.
Step 3: It was ensured that the premix was homogeneous and free from lumps. The slurry was then transferred and passed through a Dyno mill in the following manner.
GRINDING:
The premixed slurry was passed through the Dyno mill. The process was conducted at a minimum temperature of 5°C to 10°C before passing the material. The slurry was subjected to multiple passes for homogenization, ensuring that the particle size was maintained at less than 5 µ, with at least 3 to 4 passes.

VISCOCITY ADJUSTMENT:
The grinded material was transferred to a beaker, and xanthan gum gel was added very slowly over a period of 30 to 45 minutes until homogenization was achieved. The preservative was then added to the mixture, and the contents were mixed thoroughly for an additional 20 minutes.

PRECAUTIONS: -
1. The quantities used for gel preparation were minimized from the batch recipe as prescribed above.
2. The Dyno mill was equipped with continuous water circulation, which was maintained at a temperature of 25°C.
3. The grinded slurry was passed through a 350 Micron IS sieve.
4. The beakers used for this process were thoroughly cleaned, ensuring that no contamination occurred during the procedure.

The product arrived after the recipe was made is stable at room temperature and it also passed the heat stability test and cold test.
Evaluation of synergistic effect of composition of the present invention comprising Insecticides & Plant Growth Regulator
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 pesticidal control observed by the compound (Chlorantraniliprole) at a defined dose (equal to x).
Y is the percentage of pesticidal control observed by the compound (Deltamethrin) at a defined dose (equal to y).
Z is the percentage of pesticidal control and/or growth/yield observed by the compound (Triacontanol) at a defined dose (equal to z).
When the percentage of pesticidal control observed for the combination is greater than the expected percentage, there is a synergism effect.
Observed control (%)
Ratio = -----------------------------
Expected control (%)
Ratio of O/E > 1, synergism observed

The present invention is illustrated by way of examples, the examples are meant for illustrative purposes and should not be construed as limiting.

Experiment for Synergistic activity of composition product of present invention:

Example 1- Details of experiment on paddy crop:

Field experiment for synergistic activity of Chlorantraniliprole, Deltamethrin and Triacontanol for the control of Stem borer in paddy crop was conducted
To evaluate the synergistic effect, seeds for paddy [Variety: RNR-15048] crop sown in raised seed bed Field for experiment was ploughed and divided in plot size of 6 m x 6 m keeping 1 m buffer between plots to avoid drift of chemicals. About one month old seedlings were transplanted in the main field with 20 cm x 10 cm distance with three replications and in Randomized Block Design (RBD). The treatments were applied as single directed foliar spray @ 300 ml/ha. The active components were applied in different ternary and binary compositions. Solo compositions were also taken for comparison. The treatments T1 to T35 were applied as foliar spray and in T36 control treatment only water was sprayed. The data thus obtained were analyzed from ten hills per replication.

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

Corrected Stem borer Reduction (%): The % reduction in corrected stem borer reduction was worked out using the Abbott’s formula:

1- (Number of insects in Treated after treatment ÷ (number of insects in control after treatment) 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.

It is clearly evident from the data shown in above Table 1 for per cent Stem borer control in paddy crop that the ternary composition of the present invention comprising Chlorantraniliprole, Deltamethrin and Triacontanol T1 to T5 are highly synergistic with > 1 Colby’s Ratio. The binary compositions Chlorantraniliprole + Deltamethrin (T6 to T10), Chlorantraniliprole + Triacontanol (T11 to T15) and Deltamethrin + Triacontanol (T16 to T20) are compatible but non-synergistic for the control of Stem borer as compared to ternary composition comprising Chlorantraniliprole, Deltamethrin and Triacontanol. The binary compositions are thus less effective to control Stem borer as compared to ternary compositions comprising Chlorantraniliprole + Deltamethrin + Triacontanol (T1 to T5).

Observations were also made on plant height, no. of tillers per hill and grain yield.
Plant height and no of tillers were recorded at 90 days after transplanting and increase was calculated against control. The results of the trial have been presented here under in Table 2 and 3. Similarly, the grain yield was calculated at harvest and percent increase was calculated against control and presented in Table 4. Based on % increase against control in solo treatments the Expected control was calculated and compared with Observed control.

It is clearly evident from the data shown in above Table 2 for per cent increase in plant height in paddy crop that the ternary composition of the present invention comprising Chlorantraniliprole, Deltamethrin and Triacontanol T1 to T5 are highly synergistic with > 1 Colby’s Ratio. The binary compositions Chlorantraniliprole + Deltamethrin (T6 to T10), Chlorantraniliprole + Triacontanol (T11 to T15) and Deltamethrin + Triacontanol (T16 to T20) are compatible but non-synergistic as compared to ternary composition comprising Chlorantraniliprole, Deltamethrin and Triacontanol. The binary compositions are thus less effective as compared to ternary composition comprising Chlorantraniliprole + Deltamethrin + Triacontanol (T1 to T5).
