Description

[0001] STABLE SYNERGISTIC AGROCHEMICAL COMPOSITION FIELD OF THE INVENTION

[0002] The present invention relates to a stable synergistic agrochemical composition comprising A) Brassinolide or its agrochemically acceptable salts, esters and derivatives; B) Gibberellic acid or its agrochemically acceptable salts, esters and derivatives; C) Triacontan-l-ol or its agrochemically acceptable salts, esters and derivatives; and D) bio- effective amount of Sulphur, for synergistic and effective plant growth regulation, activation and stimulation The present invention also relates to a process for preparation of such stable synergistic agrochemical composition for synergistic and effective plant growth regulation, activation and stimulation.

[0003] BACKGROUND OF THE INVENTION

[0004] Plant growth regulators, plant stimulators and plant activators are transmitted to the site of action in plants and promote or inhibit certain aspects of their life processes at very low concentrations to meet agricultural and horticultural requirements. Depending on the crop species, growth stages, and application objective, such agents regulate a wide range of plant functions, for example: dormancy; promoting cell growth and division; plant height promoting rooting; controlling germination controlling lateral buds or tillers; controlling plant type, such as stunting and lodging; controlling flowering or Male and female sex, induce no fruit; flower thinning, number of flowers, control fruit drop; control fruit shape or maturity; enhance stress resistance, such as disease resistance, drought resistance, salt tolerance, antifreeze; enhance absorption of fertilizer; increase sugar or change acidity; improve fragrance and color; promote latex or resin secretion; defoliation or evasion.

[0005] Various plant growth regulators, stimulators and activators have long been known and employed for influencing variety of plant growth and development. Amongst one of the effective plant growth stimulator / activators, i.e., Brassinolide is observed, that is also referred as a plant hormone. Brassinolide is oligodynamic in nature and affects specific target tissues that are sensitive to the plant hormone such as but not limited to indole-3-acetic-acid (IAA). It is a biologically active steroidal lactone first isolated from rape pollen that stimulates growth of green plant tissues. It promotes cell division; promote vascular differentiation; protects plants during cold and drought stress; promotes resistance to salt stress; increases the metabolism of plants.

[0006] Brassinolide is also known to improve pollen tube growth and showed increasing and decreasing effect on pollen viability and germination. It is one of the most effective plant growth activators, whose function is to encourage growth and resist various stresses facing plants.

[0007] Another pivotal plant growth regulator is gibberellic acid, which is used in the present invention due to its beneficial influence on seed germination, stem growth, root growth, adventitious root formation and juvenility in many vegetable crops. It shows to exhibit stimulation of cell division and elongation andinternodal extension, germination of seeds, prevention of genetic dwarfism, dormancy and extending shelf life.

[0008] Gibberellic acid belongs to gibberellin class of compound, that is one of the longest-known classes of plant hormone, and is also known as gibberellin A3 or Gibberellic acid (GA). It shows to improve nutritive value by improving plant growth, photosynthetic and remain physiologically more active to build up of sufficient food reserves. Gibberellic acid show to increase growth and development in plants or plants parts due to the exogenous application of growth regulators that may be attributed to enhance cell division, increase carbohydrate hydrolysis and cell wall plasticity.

[0009] Further, one of the effective plant growth regulators, is Triacontan-l-ol that also works as a biostimulant. It is a natural chemical that acts as a phytohormone which is used in commercial horticulture as a plant growth regulator including but not limited to ornamental plants including roses; Cotton; Tomato; Chilli peppers; Rice; Peanuts; Potato, etc. It effects photosynthesis, plant metabolism, and increase the growth of roots, shoots and flower production and influences nutrient uptake. In addition to plant growth regulators, sulphur plays an important dual role as a secondary plant nutrient and is indispensable for amino acid and protein synthesis, chlorophyll formation, and enzymatic activity. Sulphur also enhances phosphorus uptake in the root zone and, in synergy with phosphorus, facilitates the absorption of micronutrients such as zinc, iron, and manganese.Plants deficient in sulphur exhibit poor utilization of aforementioned primary nutrients such as nitrogen, phosphorus and potassium, resulting in significant reduction in enzymatic and metabolic activities at all stages of plant growth which has become a significant concern for farmers

[0010] Beyond its nutritional role, sulphur improves soil structure, supports microbial activity, and maintains pH balance, thereby contributing to long-term soil fertility. It also improves tolerance to abiotic stresses by supporting metabolic activity under adverse conditions. Similar to plant growth regulators, the effect of sulphur is dependent on the dose and rate of application, wherein deficiency adversely affects protein metabolism and chlorophyll formation ultimately affecting growth parameters such as plant height and number of flowers, etc, while excessive application may lead to soil acidification and nutrient imbalance. Under sulphur-deficient conditions, plants may exhibit excessive vegetative elongation, increased stem or neck thickness, and inadequate development of storage or reproductive organs, which is attributed to inefficient translocation of assimilates within the plant. Additionally, an important agronomic advantage of sulphur is its residual availability, as applied sulphur can remain in the soil and be subsequently utilized by following crops, such as mustard. This residual effect allows sulphur to provide benefits beyond a single cropping season and supports more sustainable crop rotation practices. There are various prior arts known that discloses a composition comprising plant growth regulators, stimulators, activators and trace elements, however, synergistic effect as attributed by the combination of plant growth regulators and plant activator with sulphur is not specifically known in the art.Moreover, there still exists a need for an alternative synergistic composition in optimum quantities / efficacious amounts / weight % range.

[0011] References can be made to CN103563986A, which discloses a plant growth regulating composition comprising active ingredient A and active ingredient B in a ratio of 70:1-1:300. Active ingredient A is triacontan-l-ol and active ingredient B is selected from the group consisting of benzylaminopurine, brassinolide, amine fresh ester, and humic acid.

[0012] Further, CN104026127A also discloses a plant growth regulator composition comprising diethyl aminoethyl hexanoate and triacontan-l-ol. Therefore, there still exists a need for an alternative synergistic composition which facilitates enhanced plant growth along with sustained agronomic benefits.

[0013] Thus, there arise a need to develop a stable synergistic agrochemical composition with a combination of plant growth regulators, plant activator and reduced amount of sulphur including sulphur in all its forms which are compatible with each other in terms of stability and ensures enhanced bio-efficacy and synergistic effect.

[0014] The stable synergistic agrochemical composition comprising Brassinolide, gibberellic acid, triacontanol and sulphur including their agrochemically acceptable salts, esters, derivatives exhibits a synergistic enhancement in both vegetative and reproductive growth parameters, leading to improved yield attributes and flowering uniformity, which is not achieved by compositions lacking gibberellic acid. The addition of gibberellic acid specifically promotes cell elongation and internodal extension. As a result, the quaternary composition of the present invention exhibits superior plant height, canopy development, and biomass accumulation compared to the composition without gibberellic acid. Gibberellic acid plays a crucial role in flower initiation, floral differentiation, and fruit set. Under abiotic stress (heat, drought, transplant shock), gibberellic acid aids in rapid growth resumption by restoring cell elongation and hormonal balance. When combined with brassinolide, triacontanol, and sulphur, the stable synergistic agrochemical composition of the present invention enables faster recovery and uniform regrowth.

[0015] It has been found that by virtue of composition of present invention, the plant growth regulation of a Brassinolide is significantly enhanced when combined with other plant growth regulators especially Gibberellic acid and triaconta-l-ol along with bioactive amount of sulphur.

[0016] 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 and is safe to use.Therefore, present invention aims to overcome the problems of the prior arts and provide a stable synergistic agrochemical composition comprising A) Brassinolide or its agrochemically acceptable salts, esters and derivatives; B) Gibberellic acid or its agrochemically acceptable salts, esters and derivatives; C) Triacontan-l-ol or its agrochemically acceptable salts, esters and derivatives; and D) bio- effective amount of Sulphur, for synergistic and effective plant growth regulation, stimulation and activation.

However, it is not intended that the invention be limited to specific terms so selected and it is to be understood that each specific term includes all technical equivalents that operate in a similar manner to accomplish a similar purpose.

[0102] The terminology used herein is solely for describing particular embodiments and shall not limit the scope of the invention.

[0103] All technical and scientific terms used herein have meanings commonly understood by one skilled in the art of agrochemical formulations, plant growth regulation, and crop protection.Terms such as “a,” “an,” and “the” may include plural forms unless the context clearly dictates otherwise. The term “or” includes “and / or” unless explicitly stated.

[0104] The transitional phrases “comprise,” “comprising,” “including,” and “having” are intended to be open-ended, specifying the presence of stated components or steps without precluding additional features, components, or operations.

[0105] The term “synergistic” refers to the combined effect of the actives, which is greater than the sum of their individual effects, resulting in enhanced plant growth, nutrient uptake, stress tolerance, and yield improvement. The term “effective amount” refers to an amount sufficient to produce the desired plant growth regulatory effect when applied to plants, crops, or propagation materials.

[0106] The term “plant health” or “health of a plant” refers to a condition of the plant wherein improved vigour, growth, and resilience to abiotic or biotic stresses are achieved, resulting in increased yield and / or improved quality of plant products.

[0107] The term “crop” shall include a multitude of desired crop or plants or an individual crop or plant growing at a locus.

[0108] The term “plant growth regulator (PGR)” refers to organic substance, other than nutrients, which influences the physiological processes of plants or crops.

[0109] The term “plant growth stimulator” encompasses compounds, mixtures, or formulations capable of modulating plant metabolic activity, including but not limited to cell division, photosynthesis, nutrient uptake efficiency, flowering, fruit set, biomass accumulation, yield enhancement, stress tolerance, or recovery from abiotic or biotic stress, when applied at biologically effective but non-phytotoxic amounts.

[0110] A bio-effective amount is an amount that produces a statistically or agronomically significant improvement in at least one growth-related parameter selected from, but not limited to, germination, root or shoot development, plant height, number of flowers, biomass accumulation, nutrient uptake efficiency, flowering, fruit set, yield, or stress tolerance, when compared to an untreated control or standard practice.The term ‘agrochemically effective amount’ refers to the quantity of the active ingredient(s) that is sufficient to produce the intended beneficial effect in plants, parts of plants, or their loci, including but not limited to stimulation of growth, regulation of development, enhancement of yield, improvement of quality, or protection against biotic or abiotic stress, without causing phytotoxicity or undesirable side effects. The actual agrochemically effective amount may vary depending on factors such as the nature of the active ingredient, type of crop, stage of plant growth, environmental conditions, and method of application.”

[0111] The term “synergistic” refers to the combined effect of the actives, which is greater than the sum of their individual effects, resulting in enhanced plant growth, nutrient uptake, stress tolerance, and yield improvement.

[0112] The term “Sulphur, comprising elemental sulphur and all agrochemically acceptable forms, derivatives, complexes, and formulations thereof’ refers to the sulphur component used in the present invention that may be provided in any agrochemically acceptable form capable of delivering bioavailable sulphur for agricultural use. Suitable forms include elemental sulphur such as but not limited to wettable sulphur, colloidal or micronized sulphur, sublimed or precipitated sulphur, as well as sulphur in the form of dispersible granules or suspension concentrates. Additionally, agrochemically acceptable derivatives or complexes of sulphur such as but not limited to calcium polysulphide (lime sulphur), other polysulphides, or sulphur-surfactant or sulphur-clay complexes may also be employed, provided that they are conventionally recognized for agricultural application. Further, sulphur may be incorporated into standard agrochemical formulations, with appropriate carriers or adjuvants. All such forms are intended to be encompassed within the term ‘sulphur’ as used herein, to the extent that they remain compatible with the claimed composition and exhibit acceptable agricultural utility.

[0113] The term ‘bioavailable sulphur’ as used herein refers to sulphur in any agrochemically acceptable form capable of releasing plant-usable sulphur under field conditions.

[0114] As used herein, the terms “bioactive quantity,” “efficacious amount,” or “effective weight percentage” refer to the amount of sulphur, or any other active ingredient of the present composition, which is sufficient to produce the intended agronomic response, including but not limited to enhancement of plant growth, improvement of nutrient assimilation, stimulation of physiological activity, or improvement of pest, disease, or stress tolerance. The bioactive or efficacious amount of sulphur corresponds to the quantity that provides available sulphur in aphysiologically utilizable form, without causing phytotoxicity, formulation instability, or adverse interaction with the other active components.

[0115] In the context of the present invention, sulphur may be employed in a concentration typically ranging from 0.001% to 10% by weight of the total composition, depending on the formulation type, mode of application, and compatibility with the accompanying plant growth regulators. The skilled person will recognize that the precise efficacious amount for sulphur, as well as for the other actives herein, may vary depending on the target crop, application method, and environmental conditions, and can be readily determined through routine optimization without undue experimentation.

[0116] As used herein, the expressions “in optimum quantities,” of each constituent, including sulphur and the accompanying plant growth regulators, corresponds to the concentration that provides maximum functional benefit under practical field or formulation conditions. Such amounts typically fall within a weight percentage range that can vary depending on the formulation type, but are readily determinable by a person skilled in the art through routine formulation trials and optimization without undue experimentation.

[0117] The term “essential nutrient” refers to an element or compound that is required by plants which plays an essential role in their growth, development, metabolism, and overall physiological functions. The term is intended to encompass such elements / compounds, which are capable of correcting or preventing deficiencies and improving plant health and productivity.

[0118] Accordingly, in an especially preferred embodiment according to the invention, the health of a plant is increased both in the presence and absence of biotic or abiotic stress factors. An increase in plant vigor may for example result in an increased yield and / or tolerance to abiotic or biotic stress.

[0294] Evaluation of synergistic effect of pesticidal composition of the present invention

[0295] 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.

[0296] 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.

[0297] The synergistic action expected for a given combination of two active components can be calculated as follows:

[0298] XY

[0299] E = (X + Y) - - 100

[0300] The synergistic action expected for a given combination of three active components can be calculated as follows:

[0301] (XY+YZ+XZ) (XYZ)

[0302] E = (X + Y + Z) - - + - 100 10000 (XY+XZ+XW+YZ+YW+ZW) (XYZ+XYW+XZW+YZW) XYZW E = (X+Y+Z+W) - - + - + - 100 10000 1000000

[0303] Where:

[0304] E represents expected percentage of respective technical effect (i.e., leaf area index and number of flower opened) for the composition comprising of the two or three actives’ ingredients at defined doses (for example equal to x, y and z, respectively).

[0305] W is the percentage of respective technical effect (i.e., plant height and number of fruits) observed by the compound (Brassinolide) at a defined dose (equal to w).

[0306] X is the percentage of respective technical effect (i.e., plant height and number of fruits) observed by the compound (Triacontanol) at a defined dose (equal to x).Y is the percentage of respective technical effect (i.e., plant height and number of fruits) observed by the compound (Gibberellic acid) at a defined dose (equal to y).

[0307] Z is the percentage of respective technical effect (i.e., plant height and number of fruits) observed by the compound (Sulphur) at a defined dose (equal to z).

[0308] When the percentage of relevant technical effect observed for the combination is greater than the expected percentage, there is a synergism effect.

[0309] Observed control (%)

[0310] Ratio = - Expected control (%)

[0311] Ratio of O / E > 1, synergism observed

[0312] The present invention is illustrated by way of examples, the examples are meant for illustrative purposes and should not be construed as limiting.

[0313] Experiment for Synergistic activity of composition of present invention:

[0314] Example 1- Details of experiment on tomato crop:

[0315] A field experiment was conducted to study the synergistic effect of Brassinolide + Triacontanol + Gibberellic acid + Sulphur on plant height and number of fruits in tomato crop variety Arka Vikas, in Shivamogga.

[0316] To evaluate the synergistic effect, tomato crop was sown in 6 m x 5 m plots maintaining 60 cm x 45 cm plant distance with three replications and in Randomized Block Design (RBD). The treatments were applied as foliar spray in the form of SC formulation @ 250 ml / ha. The treatment details are as under:

[0317]

[0318]

[0319]

[0320] The treatments T1 to T56 were used as foliar application whereas no treatment was done for T57 control treatment. Two applications at 15 days interval were done of all treatments after 60 days of crop sowing. Plant height and number of fruits were recorded at 14 days after the 1st and 2nd applications. For each observation, ten randomly selected plants per plot were tagged and measured. Plant height was measured from the soil surface to the apical growing point using a measuring scale or measuring tape. The number of fruits per plant was recorded by counting all marketable and unmarketable fruits present on the tagged plants at each observation interval. Only fruits that had reached the physiological fruitsetting stage were considered in the count. The plot-wise mean plant height and mean fruit number were calculated by averaging the observations from the ten sampled plants. Standard crop management practices were followed to avoid any bias in data collection and to ensure uniformity across treatments. Based on the per cent change at 14 days after second spray, expected control was calculated and compared with observed control. The results of the trial have been presented here under in Table 1 Table 1: Synergistic effect of composition of the present invention (Brassinolide + Triacontanol + Gibberellic acid + Sulphur) against different agronomic character in tomato crop

[0333] The synergistic composition of the present invention Brassinolide 0.01% + Triacontanol 0.05% + Gibberellic acid 0.01% + Sulphur 4%SC was evaluated on tomato crop. The crop sowing was done in Randomized Block Design (RBD) with three replications maintaining a distance of 60 cm x 45 cm between plants and rows.

[0334] The observations were recorded for the following objectives.

[0335] Objectives:

[0336] 1. Efficacy of Brassinolide + Triacontanol + Gibberellic acid + Sulphur on plant height in tomato crop.

[0337] 2. Efficacy effect of Brassinolide + Triacontanol + Gibberellic acid + Sulphur on number of fruits number in tomato crop.

[0338] 3. Efficacy evaluation based on per cent change in plant height in tomato over control

[0339] 4. Efficacy evaluation based on percent change in fruits number in tomato over control

[0340] 5. Efficacy as well synergistic effect evaluation based on crop yield.

[0341] Methodology:The treatments T1 to T28 and T30 (Table 2) were used as foliar application whereas no treatment was done for T29 (Table 2) i.e., control treatment. All treatments were applied after 35 days of crop sowing in the experimental plots. For each observation, ten randomly selected plants per plot were tagged and measured. Plant height was measured from the soil surface to the apical growing point using a measuring scale or measuring tape. The number of fruits per plant was recorded by counting all marketable and unmarketable fruits present on the tagged plants at each observation interval. Only fruits that had reached the physiological fruit-setting stage were considered in the count. The plot-wise mean plant height and mean fruit number were calculated by averaging the observations from the ten sampled plants. Standard crop management practices were followed to avoid any bias in data collection and to ensure uniformity across treatments.
