NOVEL FUNGICIDAL COMPOSITION FIELD OF THE INVENTION The invention relates to a synergistic fungicidal composition comprising combination of an effective amount of Bixafen and an effective amount of Ametoctradin or an effective amount of Carboxin and at least one agrochemically acceptable excipient. The invention particularly relates to a fungicidal composition comprising combination of Bixafen in the range of 0.1% w/w to 70% w/w of the total composition, Ametoctradin in the range of 0.1% w/w to 60% w/w of the total composition or Carboxin in the range of 0.1% w/w to 60% w/w of the total composition and at least one agrochemically acceptable excipient. The fungicidal composition has particles in the size range of 0.1 micron to 50 microns. The invention further relates to a process of preparing the fungicidal composition comprising combination of Bixafen and Ametoctradin or Carboxin. The invention furthermore relates to a method of protecting crops by combating fungi and improving plant health and yield, the method comprising applying to the fungi or plant, plant parts, plant propagation material, seed, seedling or surrounding soil with the fungicidal composition of the present invention. BACKGROUND OF THE INVENTION In describing the embodiment of the invention, specific terminology is chosen for the sake of clarity. However, it is not intended that the invention be limited to the 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. Fungal pathogens are extremely dangerous and may cause the loss of crop harvests or, in the most serious cases, the death of the plants. Fungi can also negatively affect the quality of crops, causing an accumulation of toxins within the plants. The toxins produced by some fungi are dangerous for humans and animals. Again presently, the planting area of economic crops is gradually expanding and with the degree of occurrence and the number of diseases also increasing, it is becoming more and more difficult to effectively control plant pathogens. Use of agrochemicals, in particular chemical fungicides, for protection of crops against fungi and other pests has been an integral component of crop management. However, current fungicides available in the market do not meet the modern-day crop protection requirements, as they: ^ lack in providing a broad spectrum of action, ^ unsatisfactory efficacy ^ exhibit increased resistance among the fungi/diseases due to the repeated and prolonged administration of the individual actives or known chemistries at higher dosages, ^ lead to environmental pollution and soil toxicity due to application of pesticides at higher dosages and the leaching of pesticides in soil and groundwater. In addition, the repeated use of the current pesticidal products also exhibits problems such as pest resurgence, secondary pest outbreak, residue related problems, toxic effect on human beings along with reduced yield. Hence, there is a need for developing newer pesticidal products in particular fungicidal products, which addresses the above drawbacks associated with the known chemistries. Further, the use of composition containing multiple pesticides having different chemical and physical properties poses various problems such as inappropriate ratio of mixing, incompatibilities of formulated products; potential hazard to people who are not trained to properly mix products. Also, combining and preparing stable formulation comprising multiple pesticides is critical as the pesticides contained in the composition must not only be compatible but must also have prolonged shelf life with a high stability and demonstrate effective activity until end use. Hence, there is a continuous need to develop a newer pesticidal composition with modern integrated pest management not only for an improved toxicological and environmental profile but also for substantial broadening of spectrum of crop protection along with increased stability and safety to the end users. There is a further need to reduce the rate of application of the fungicidal active ingredients in order to address the adverse environmental or toxicological effects observed with the higher dosages of application of the fungicidal compositions, while also overcoming the issues of development of fungi/disease resistance and other drawbacks associated with known chemistries. Bixafen is an active ingredient from the chemical class of pyrazoles, one of the latest-generation SDHIs, which functions by inhibiting succinate dehydrogenase, an enzyme involved in the citric acid cycle and mitochondrial electron transport chain, which in turn disrupts energy production. It is a systemic fungicide widely used on cereal and rapeseed crops and proposed for use against many fungal diseases (e.g., rusts and glume blotch of wheat, gray leaf spot, and rust of corn). It was developed specifically for foliar application to control important cereal diseases such as septoria leaf blotch (Septoria tritici) in intensive cereal growing regions. Ametoctradin, is a triazolopyrimidine fungicide. It is an oomycete-specific fungicide, as it is a potent inhibitor of mitochondrial bc1 complex of oomycetes in mitochondrial respiration. It is used to control major plant pathogens from the Oomycete class of fungi, specifically downy mildews and Phytophthora species on brassica leafy vegetables, bulb vegetables, cucurbit vegetables, fruiting vegetables, grapes, hops, lettuce (head and leaf), and potatoes. Carboxin was the first SDHI-type fungicide. Owing to its systemic properties, Carboxin is suitable for use as a seed treatment to give fungal control on the growing crop. Carboxin is used for control of bunts and smuts normally used as a seed treatment and is also effective against damping-off diseases caused by Rhizoctonia and against the various smuts of grain crops. However, there is a need in the art to improve on the disease spectrum provided by these actives, particularly with a view to overcoming the resistance being developed to these fungicides. There are a lot of arts which discloses combination of SDHI fungicides including Bixafen or Carboxin with another fungicide of different mode of action or chemical classes. For instance, WO2022018767A1, WO2018162999A1, WO2021111384A1, WO2018083577A1, WO2005034628A1, WO2007012598A1 discloses combinations of SDHI fungicides with one or more other class of fungicides. Similarly, various products and arts viz. US20080234295A1, US20130023412A1 disclosing combination of Ametoctradin with other fungicides are also known. However, efficacy or spectrum of disease control by some of the combinations known or disclosed in the art are not entirely satisfactory especially when applied at lower active dosage. These reports, however, are silent on the specific combination of Bixafen and Ametoctradin or Carboxin in a pesticidal effective amount with a specific particle size; and on the efficacy and the synergy of the said combination. Thus, no fungicidal composition known in the art comprising of specific combination of Bixafen and Ametoctradin or Carboxin which can be effectively used with broad spectrum fungicidal activity at lower dosage and address the drawbacks discussed above with the known compositions. That need is solved according to the present invention by the provision of the present stable and improved fungicidal combination. The inventors have surprisingly found out that the combination of Bixafen and Ametoctradin or Carboxin exhibits synergy. Further, they have developed a stable synergistic fungicidal composition comprising an effective amount of Bixafen and an effective amount of Ametoctradin or an effective amount of Carboxin and at least one agrochemically acceptable excipient, which acts as a superior crop- protectant, is effective at reduced dosages of application, helps in the resistance management observed with the old pesticide chemistry, is non-phytotoxic and also demonstrates increased yield on field application, while broadening the spectrum of crop protection in terms of fungus/disease control over wide variety of fungal diseases such as Rust, Downy mildew, Powdery mildew, Late blight, Loose smut, Collar rot, Leaf spot (Alterneria), Stem rot, Septoria, Phythium, Rhizoctonia etc. The fungicidal composition of the invention comprises particles in the size range of 0.1 micron to 50 microns and thereby exhibits superior physical characteristics such as suspensibility, dispersibility, flowability and wettability. The fungicidal composition with a particle size range of 0.1 micron to 50 microns results in an increased surface area coverage on application to the plants or the plant propagation material which enhances adhesion and provides better penetration of the active moieties when applied and also facilitates better absorption by the roots when applied to the surrounding soil improving their efficacy and bioavailability. It is observed that the uptake or effectiveness of the active ingredients comprised in the composition is particularly higher where the composition has particles in the size range of about 0.1 micron to 50 microns. Thus, the particle size range of 0.1 micron to 50 microns of the fungicidal composition was found to be significant not only in terms of ease of application but also in terms of efficacy. The compositions of the present invention also demonstrated superior performance under accelerated storage and also surprisingly be used effectively in modern irrigation systems.

FIELD STUDY: The following are some abbreviations that have been used in the field study data. ^ WG: Water dispersible granule ^ SC: Aqueous suspension ^ DG: Water disintegrable Granules ^ FS: Flowable Concentrate for seed treatment ^ DS: Powder for dry seed treatment ^ WS: Water dispersible powder for slurry seed treatment ^ p.s.: Particle size of the composition ^ *: Expected effect (disease reduction or increase in yield) calculated by Colby’s method ^ UTC: Untreated control ^ DAA: Days after application ^ DAS: Days after sawing ^ 1SP: 1st spray application, ^ 2SP: 2nd spray application ^ PDI: Percent Disease Index ^ g/ha: Grams per hectare ^ g.a.h.: gram active ingredient per hectare ^ Qtl/ha: Quintal per hectare ^ T/Ha: Tons per hectare The percentage reduction of disease incidence over UTC was calculated using the following formula: % Reduction = [(PDI in control plot – PDI in treated plot) / PDI in control plot] X 100 Further, the percentage increase in yield over UTC was calculated using the following formula: Increase (%) = [(Crop yield in treated plot – Crop yield in control plot) / Crop yield in control plot] X 100 Synergy evaluation using Colby's formula: “Synergy” is as defined by Colby S. R. in an article entitled “Calculation of the synergistic and antagonistic responses of herbicide combinations” published in Weeds, 1967, 15, p. 20-22. The action expected for a given combination of two active components can be calculated as follows: E = X + Y - (XY/100) Where, E= Expected % effect by mixture of two products X and Y in a defined dose. X= Observed % effect by product A Y= Observed % effect by product B The synergy factor (SF) is calculated by Abbott’s formula Eq.(2) (Abbott, 1925). SF= Observed effect /Expected effect Where, SF >1 for Synergistic reaction; SF<1 for antagonistic reaction; SF=1 for additive reaction. When the percentage of effect (pest/disease reduction or yield increase) observed for the combination is greater than the expected percentage effect (E) i.e. SF >1, the synergistic effect of the combination is inferred. When the percentage of effect (pest/disease reduction or yield increase) observed for the combination is equal to the expected percentage effect (E) i.e. SF=1, merely an additive effect may be inferred, and wherein the percentage of effect (pest/disease reduction or yield increase) observed for the combination is lower than the expected percentage effect (E) i.e. SF<1, an antagonistic effect of the combinations is inferred. Field trial 1: To study effect of combination of Bixafen and Ametoctradin against leaf Rust in Wheat. The field trial was carried out to study the effect of the composition of Bixafen and Ametoctradin at different concentrations in WG, SC and WP form against leaf Rust in Wheat. The trial was carried out by Randomized Block Design (RBD) with seven treatments including untreated control, replicated four times. The Wheat in trial field was raised following good agricultural practice.

The observations on disease (Leaf rust) incidence were recorded by measuring rust severity percentage from 5 leaves each from 3 plants per treatments at 10 Days after second spray. Percent disease index (PDI) was calculated for the diseases using 0- 5 scale wherein 0= no infection, 1= 1-10 percent leaf area infected, 3= 26-50 percent leaf area infected, 4= 51-75 percent leaf area infected. Percent Disease Index (PDI) was presented in Table 1 to see the impact of the composition of the present invention on disease control (Leaf Rust) in Wheat. Based on the data percent reduction in disease incidence over untreated control was calculated and was presented in Table 1. The observations on yield parameter were also recorded at the harvesting time and mean data were presented in Table 1.

Based on the data and the calculations, the expected percentage reduction of wheat rust for combination of Bixafen and Ametoctradin was 84.39%. However, it can be clearly seen from Table 1 above that the Treatments T1, T2 and T4 showed 94.27%, 92.75% and 86.01% reduction in disease over the untreated control respectively which is better than the percentage disease reduction observed for the individual treatments with Bixafen and Ametoctradin which showed reduction in disease over the untreated control of only 65.34% and 54.97% respectively. The disease reduction observed with treatments T1, T2 and T4 were also higher than the expected reduction in disease calculated as per Colby’s method, depicting the synergistic nature of the composition. Thus, the treatments T1, T2 and T4 with the compositions as per the embodiments of the present invention demonstrated a synergistic effect compared to the application with individual actives i.e. treatments T5 and T6. The results are all the more surprising as the treatments T1, T2 and T4 and individual treatments T5 and T6 had the same dosage of actives being applied i.e.50 g/ha of Bixafen and 100 g/ha of Ametoctradin. In addition, it can be observed that treatment 3 (T3) with Bixafen 25% + Ametoctradin 50% WG as per the embodiment of the present invention wherein actives were applied at reduced dosage i.e. Bixafen was applied @44 g/ha and Ametoctradin was applied @88 g/ha demonstrated superior control over wheat rust as compared to standalone actives i.e. treatments T5 with Bixafen @50 g/ha and T6 with Ametoctradin @100 g/ha. The results are more surprising as the treatment T3 demonstrated 90.96% reduction in disease over untreated control which was also higher than the expected disease reduction calculated by Colby’s method i.e. 84.39%, even though treatments T3 was applied at reduced active dosage. Further, it can be observed that the composition as per the embodiment of the present invention comprising combination of Bixafen and Ametoctradin, on account of significant control of the fungus also resulted in a substantial enhancement in the yield, as compared to the yield observed with individual applications of Bixafen and Ametoctradin. It can be seen that Treatments T1, T2, T3 and T4 showed 50.63%, 48.63%, 40.88% and 34.50% increase in yield over the untreated control respectively which is higher than the expected increase in yield calculated by Colby’s method i.e.32.55%. The surprising synergistic result of treatments T1 to T4 is attributed to the composition of Bixafen and Ametoctradin as per the embodiments of the invention, where these two actives are present in a single composition at a specific concentration. The enhanced efficacy is further attributed to the form of the composition, i.e. water dispersible composition, suspension concentrate and wettable powder composition as shown in the present study, which includes particles in the size range of 0.1 micron to 50 microns. Field trial 2: To study effect of combination of Bixafen and Ametoctradin against Late blight in Potato.

It can be observed that percentage disease reduction for treatment T1 is also higher than the expected percentage disease reduction calculated by Colby’s method i.e.64.26%. Thus, the treatments T1 with the compositions as per the embodiments of the present invention demonstrated a synergistic effect compared to the application with individual actives i.e. treatments T4 and T5. The results are all the more surprising as the treatments T1 with the combination of actives and individual treatments T4 and T5 had the same dosage of actives being applied i.e.72 g/ha of Bixafen and 216 g/ha of Ametoctradin. In addition, it can be observed from table 2 that treatment 2 (T2) and treatment 3 (T3) which were applied at reduced dosage of actives as compared to stand alone actives also demonstrated 89.80% and 91.84% reduction in disease over untreated control respectively which is also higher than the expected disease reduction i.e. 64.26%. It was surprising to observe that treatments T2 and T3 with the composition of the present invention even though applied at reduced dosage as compared to standalone actives demonstrated superior control over wheat rust. It was also observed that the treatments T1 to T3 with the composition as per the embodiment of the present invention comprising combination of Bixafen and Ametoctradin, on account of significant control of the fungus also resulted in a substantial enhancement in the yield, as compared to the yield observed for treatments T4 and T5 with individual applications of Bixafen and Ametoctradin. It can be seen that treatments T1, T2 and T3 showed 60.40%, 54.27% and 56.00% increase in yield over the untreated control respectively which is higher than the expected increase in yield calculated by Colby’s method i.e.45.55%.

It can be observed that percentage disease reduction for treatment T1 is also higher than the expected percentage disease reduction calculated by Colby’s method i.e. 71.07%. Thus, the treatment T1 with the compositions as per the embodiments of the present invention demonstrated a synergistic effect compared to the application with individual actives i.e. treatments T4 and T5. The results are all the more surprising as the treatments T1 with the combination of actives and individual treatments T4 and T5 had the same dosage of actives being applied i.e.216 g/ha of Bixafen and 216 g/ha of Ametoctradin. In addition, it can be observed from table 2 that treatment 2 (T2) and treatment 3 (T3) which were applied at reduced dosage of actives as compared to stand alone actives also demonstrated 87.78% and 82.96% reduction in disease over untreated control respectively which is higher than the expected disease reduction i.e. 71.07%.

Thus, it was surprisingly noted that even amongst the WG formulations, superior efficacy was observed with WG formulation having a specific particle size distribution of 0.1 to 50 microns in comparison to WG formulations having different particle sizes in varied ranges. Field trial 5: To study effect of combination of Bixafen and Carboxin against Rust in Groundnut. The field trial was carried out to study the effect of the composition of Bixafen and Carboxin in different concentrations in WG, SC and WP form against leaf Rust in Groundnut. The trial was carried out by Randomized Block Design (RBD) with seven treatments including untreated control, replicated four times. The Groundnut in trial field was raised following good agricultural practice.

The observations on disease (Leaf rust) incidence were recorded by measuring rust severity percentage from 5 leaves each from 3 plants per treatments at 10 Days after second spray. Percent disease index (PDI) was calculated for the diseases using 0-5 scale wherein 0= no infection, 1= 1-10 percent leaf area infected, 3= 26-50 percent leaf area infected, 4= 51-75 percent leaf area infected. Based on the data percent reduction in disease incidence was calculated in groundnut and presented in Table 5. The observations on yield parameter were also recorded at the harvesting time and mean data were presented in Table 5.

Based on the data and the calculations, the expected percentage reduction of leaf rust in groundnut for the combination of Bixafen and Carboxin was 74.63%. However, it can be clearly seen from Table 5 above that the Treatment T1 showed 90.03% reduction in disease over the untreated control which is better than not only the disease reduction observed for the individual treatments with Bixafen and Carboxin which showed reduction in disease over the untreated control of only 59.50% and 37.36% respectively but also it demonstrated higher disease reduction than expected disease reduction calculated as per Colby’s method, depicting the synergistic nature of the composition. Thus, the treatment T1 with the compositions as per the embodiments of the present invention demonstrated a synergistic effect compared to the application with individual actives i.e. treatments T4 and T5. The results are all the more surprising as the treatment T1 and individual treatments T4 and T5 had the same dosage of actives being applied i.e.37.5 g/ha of Bixafen and 275 g/ha of Carboxin. In addition, it can be observed from table 5 that treatment 2 (T2) and treatment 3 (T3) which were applied at reduced dosage of actives as compared to stand alone actives also demonstrated 88.88% and 83.23% reduction in disease over untreated control respectively. It was surprising to observe that treatments T2 and T3 with the composition of the present invention even though applied at reduced dosage as compared to standalone actives demonstrated superior control over leaf rust in groundnut. Further, it can be observed that the treatments T1 to T3 with the composition as per the embodiment of the present invention comprising combination of Bixafen and Carboxin was highly effective in controlling leaf Rust incidence in Groundnut as compared to treatment 6 (T6) with the combination of Bixafen 7.5% WG @ 500g/ha + Penthiopyrad 50% WG @550 g/ha applied as tank mixture which showed 65.38% disease reduction over untreated control. It was also observed that the treatments T1 to T3 with the composition as per the embodiment of the present invention comprising combination of Bixafen and Carboxin, on account of significant control of the fungus also resulted in a substantial enhancement in the yield, as compared to the yield observed for treatments T4, T5 and T6 with individual applications of Bixafen and Carboxin as well as comparative treatment with the tank mixture of Bixafen 7.5% WG and Penthiopyrad 50% WG. It can also be seen that Treatments T1, T2 and T3 showed 42.43%, 36.70% and 31.50% increase in yield over untreated control respectively which is higher than the expected increase in yield calculated by Colby’s method i.e.26.01%. Thus, it was observed that the composition of the present invention is not only efficacious in terms of disease control but also helps in obtaining higher yield on account of effective disease control. The surprising synergistic result of treatments T1 to T3 is attributed to the composition of Bixafen and Carboxin as per the embodiments of the invention, where these two actives are present in a single composition at a specific concentration. The enhanced efficacy is further attributed to the form of the composition, i.e. water dispersible composition, suspension concentrate and wettable powder composition as shown in the present study, which includes particles in the size range of 0.1 micron to 50 microns.

It can be observed that percentage disease reduction for treatment T1 is also higher than the expected percentage disease reduction calculated by Colby’s method i.e.51.39%. Thus, the treatments T1 with the compositions as per the embodiments of the present invention demonstrated a synergistic effect compared to the application with individual actives i.e. treatments T5 and T6. The results are all the more surprising as the treatments T1 with the combination of actives and individual treatments T5 and T6 had the same dosage of actives being applied i.e. Bixafen @0.650 g/kg of seeds of and Carboxin @0.650 g/kg of seeds. In addition, it can be observed from table 6 that treatment 2 (T2), treatment 3 (T3) and treatment 4 (T4) which were applied at reduced dosage of actives as compared to stand alone actives also demonstrated 67.89%, 66.22% and 63.22% reduction in disease incidence respectively over untreated control which is higher than the expected disease reduction i.e.51.39%.

Further, it can be observed from table 8 that treatment 1 (T1) with the composition comprising Bixafen 15% + Carboxin 5% FS with the particles in the size range of 0.1 micron to 30 microns demonstrated the highest control over loose smut. The results are all the more surprising as the treatments T1 and T2 comprising combination of Bixafen and Carboxin and having particles of the composition in the size range of 0.1 micron to 50 microns as per the embodiment of the present invention and treatments T3 and T4 comprising combination of Bixafen and Carboxin having particles in the size range beyond 0.1 to 50 microns had the same dosage of actives being applied i.e. Bixafen @0.675 g/kg of seed and Carboxin @0.225 g/kg of seed. Thus, it was surprisingly noted that even amongst the formulations, superior efficacy was observed with the formulation having a specific particle size distribution of 0.1 to 50 microns in comparison to the formulation having particles in the size range beyond 0.1 to 50 microns. Similar, results were also observed for other formulations viz. suspension concentrate, water dispersible granules and wettable powder. It was observed that the combination of the present invention provides good control of fungi or disease as compared to the application of individual actives. Further the composition of the present invention not only helps in improving the crop yield, but the plants also exhibit enhanced physiological parameters. It was observed that the compositions of the present invention, wherein the composition has a particle size in the range of 0.1 micron to 50 microns demonstrate enhanced, efficacious and superior behavior in the fields at reduced dosage. The fungicidal composition of Bixafen and Ametoctradin or Carboxin where the composition is formulated in a particle size range of 0.1 micron to 50 microns also results in enhanced dispersibility and suspensibility, resulting in even distribution of the actives with increased surface area coverage and also enhances adhesion and penetration of the actives when applied to the target site of plants or crops or their surrounding soil. These characteristics facilitates absorption of the actives improving their bioavailability and efficacy even at reduced dosages. The particle size of the composition not only provides an efficacious composition but also improves the physical properties of the composition. Thus, it has been observed that the compositions of the present invention, demonstrate enhanced, efficacious and superior behavior in the fields at reduced dosage. 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 limitation with respect to the specific embodiments illustrated is intended or should be inferred.
