DESC:A STABLE INSECTICIDAL COMPOSITION AND PREPARATION PROCESS THEREOF
FIELD OF THE INVENTION
The present invention relates to the field of agricultural pesticides and, more particularly, to a stable insecticidal composition and process of preparation thereof.
BACKGROUND OF THE INVENTION
Controlling invertebrate pests is essential for improved crop efficiency in economically important crops. These pest not only inflict damage on growing and harvested agronomic crops but also lead substantial reductions in crop yields. The pest management strategies to manage invertebrate pests involve using single active components or mixtures of two or more active compounds. However, there remains a significant demand for more cost-effective and stable insecticidal compositions.
Further, repeated and prolonged application of single compounds often leads to the development of resistance against the active compounds. Normally, such pests develop cross-resistance against other actives with the same or similar mode of action. Hence, there is a need for combinations of actives belonging to different classes and groups to allow for a broader disease control spectrum that combines curative and preventive actives and is stable.
There is an urgent need for a stable, synergistic, and environment friendly insecticidal composition. The composition should provide effective control across a wide array of insect pests, thereby preventing the emergence of resistant strains. Furthermore, it should also offer a broad-spectrum activity that minimizes the number of chemicals applied in fields, aligning with sustainable agricultural practices. Another critical factor for the composition is their stability under diverse environmental conditions, including the ability to remain effective at low temperatures where conventional actives may degrade or perform sub-optimally. This stability ensures that the composition's efficacy is preserved from the point of manufacture through to application, irrespective of climatic variations.
The present invention provides a composition that not only counteracts the resilience tactics of pests through a multi-class active strategy but also ensures consistent performance across a comprehensive temperature spectrum.

A dispersant, also known as a dispersing agent, is a substance that adsorbs onto the surface of particles, preserving their dispersion and preventing them from reaggregating. Dispersants are added to agrochemical formulations to aid in particle dispersion and suspension during manufacturing, as well as to ensure particles re-disperse in water in a spray tank. They're a common ingredient in wettable powders, suspension concentrates, and water-dispersible granules. Surfactants used as dispersants have the ability to strongly adsorb onto a particle surface and offer a charged or steric barrier to particle re-aggregation. Surfactants that are often employed are anionic, non-ionic, or mixes of the two. Sodium lingo sulphonates are the most often used dispersants in wettable powder compositions.

Water-based formulations often cause foam during mixing operations in production. In order to reduce the tendency for foaming, anti-foaming agents are often added either during the production stage or before filling bottles. Generally, there are two types of anti-foaming agents, namely silicones and non-silicones. Silicones are usually aqueous emulsions of dimethyl polysiloxane, while the non-silicone 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.
Antifoaming agent(s) may be selected from the group comprising, but not limited to, silicon emulsion based anti-foam agents, Siloxane poly alkylene oxide, Poly dimethyl Siloxane, tri siloxane ethoxylates, and mixtures thereof.

Methodology
The experiment was conducted under field conditions at Panchedu, Nellore, Andhra Pradesh, focusing on the paddy hybrid “MTU 1010”. The experimental design followed a Randomized Block Design (RBD) with three replications. Each plot covered an area of 25 square meters for precise measurements. As per the treatment schedule, the test samples were applied at pest appearance using 500 litres of water per hectare with a knapsack sprayer.
Observation
Pre-count Pest observation was taken before the spray application. Pest counts were recorded by randomly selecting five plants per replication and noting insect population for each replication. Observations were recorded on the 5th, 10th, and 15th days after the spray application.

Methodology
The experiment was conducted under field conditions at Khargone, Madhya Pradesh on cotton hybrid “Asha 1”. The experimental design followed a Randomized Block Design (RBD) with three replications. Each plot covered an area of 25 square meters, for precise measurements to be taken, 5 plants were tagged per treatment and pest count taken prior to the application. The test samples, according to the treatment schedule, were applied at pest appearance using 500 liters of water per hectare with a knapsack sprayer?fitted with hollow cone nozzle.
Observation
Pre-count Pest observation was taken before the spray application. Pest counts were recorded by randomly selecting five plants per treatment and counting number of jassids per leaf. Observations were recorded on the 3rd, 7th, and 15th days after the spray application.

Result
The recorded data revealed that the Jassid population was uniformly distributed across the experimental area prior to the application of treatments. Observations made the day before spraying showed Jassid populations ranging between 3.07 and 3.40 per plant, with no significant differences among the treatments. However, 7 days after application (DAA), all treatments resulted in a significant reduction in Jassid populations compared to the control. Among all the treatments, Dinotefuran 220 + Bifenthrin 55 g/L EC (ES) at 750 ml and 500 ml doses proved to be the most effective in reducing the Jassid population.

The recorded data revealed that the aphid population was uniformly distributed across the experimental area prior to the application of treatments. Observations made the day before spraying showed aphid populations ranging from 8.53 to 10.53 per plant, with no significant differences among the treatments. However, 3 days after application (DAA), all treatments resulted in a significant reduction in aphid populations compared to the control. Among all the treatments, Dinotefuran 220 + Bifenthrin 55 g/L EC (ES) at 750 ml and 500 ml doses were the most effective in reducing the aphid population. The above results indicate that among all the treatments, highest percent reduction over control (% ROC) was observed in Dinotefuran 220 + Bifenthrin 55 g/L EC (ES) at 750 ml, which was found to be the most effective for the reducing the aphid population.

Result
The data recorded revealed that the population of cotton bollworms remained uniform throughout the experiment area prior to the application of treatments. The observation day before spray showed that bollworm populations varied between 1-2 per plant, respectively, and there was no significant difference among all the treatments. However, after 7 DAA, all the treatments showed a significant reduction in the population of aphids compared to the control. Amongst all the treatments, Dinotefuran 220 + Bifenthrin 55 g/L EC (ES) at 750 ml and 500 ml doses was the most effective for the reduction of cotton bollworm population.

Composition with ES and without ES were subject to stability tests, specifically by assessing the appearance at various temperatures over 7 days. Examples 1 and 2 (present invention composition) having the ES, the compositions were remarkable stability across all tested temperatures: 25°C, 10°C, 5°C, 0°C, and -10°C. The compositions (examples 1 and 2) were clear, transparent liquid appearance, characterized by a yellow Color, indicating their robustness under the specified conditions.
In contrast, the example 7 (composition without ES) showed noticeable haziness and phase separation at the various temperatures (25°C, 10°C, 5°C, 0°C, and -10°C), thus confirming that said composition was unstable and lacks compatibility.
Therefore, it is evident that the present invention composition with ES is stable across various temperatures, has a desirable appearance, and extends its shelf life.
Further evaluation of the above compositions for stability at 0°C and -10°C, and solubility in water.
Table 60: Stability at 0°C and -10°C, and solubility in water.
Properties Example 1 Example 2 Example 7 Composition Without ES
Cold stability @ 0ºC for 7 days Stable Stable Unstable
Cold stability @ -10ºC for 7 days Stable Stable Unstable
Solubility in Water Emulsifiable Emulsifiable Crystallization in emulsion
Observation:
The compositions were evaluated for cold stability at both 0°C and -10°C for 7 days, alongside assessments of solubility in water.
The composition of the present invention (examples 1 and 2), formulated with ES, had excellent stability, and the emulsions maintained their desired characteristics and showed no signs of instability, demonstrating their resilience at lower temperatures.
However, example 7 (composition without ES) had multiple issues, such as compatibility problems, stability concerns, and evidence of crystallization within the emulsion. Such challenges indicate a marked deterioration in performance when the compositions are prepared without the ES, emphasizing the critical role that ES plays in enhancing the stability and overall quality of the emulsions.
From the foregoing it will be observed that numerous modifications and variations can be effectuated without departing from the true spirit and scope of the novel concepts of the present invention. It is to be understood that no limitations with respect to the specific embodiments illustrated is intended or should be inferred. It should be understood that all such modifications and improvements have been deleted herein for the sake of conciseness and readability but are properly within the scope of the following claims.
