The present invention also relates to a process for preparation of such synergistic fungicidal composition.
BACKGROUND OF THE INVENTION
Fungicides are compounds of natural or synthetic origin, which act to protect plants against damage caused by fungi. Fungicides are used extensively in modern agricultural practices. In fact, some crops cannot be grown productively without the use of fungicides. Using fungicides allows a grower to increase crop yield and quality, and thus increase the crop value. In most cases, the increase in crop value is worth at least three times the cost of the fungicide.
Most crop and ornamental plants are subject to attack by several fungi. Plant diseases due to fungi cause significant productivity losses in ornamentals, vegetable, field, cereal and fruit crops, resulting in higher consumer cost. Plant diseases can be difficult to control and in addition to being highly destructive, may develop resistance to commercial fungicides. Due to the diversity of these organisms and their potential for inciting serious disorders in combination or alone has resulted in the need for broad-spectrum disease control. Although there are numerous chemical compounds (fungicides), available to aid in prevention of diseases of plants, each of these has practical deficiencies, which restrict its use. Fungicides combinations are frequently used to improve disease control, broaden the spectrum of control, and slow resistance development. Thus, new advantageous combinations are required to provide a variety of options to best meet specific plant disease control needs. Furthermore, certain uncommon fungicides combination exhibit a greater-than-additive (i.e. synergistic) effect to providing commercially significant levels of plant disease control.
When two or more substances in combination demonstrate unexpectedly high biological activity, for example fungicidal activity, the resulting phenomenon is known as synergism.
In order to achieve high crop productivity, it is important to protect the plant from damages caused by plant pathogenic (disease-causing) organisms.
Furthermore, there has been a need in the art to provide a synergistic fungicidal composition comprising two or more fungicides which have different mechanism of action that provide broad spectrum control while having lower rate of application and dose and yet providing enhanced efficacy and plant/crop yield. Moreover, improved rainfastness with such fungicidal composition comprising two or more fungicides has been identified in the prior arts. As a result, there has been a need to provide a fungicidal composition comprising with two or more fungicides that are stable with each other while still providing enhanced efficacy and synergistic effect over the solo formulations of the respective active ingredients.
Conventional fungicide compositions comprising acylamino acid fungicide with anti-peronosporic activity may not provide a practically sufficient control effect on plant diseases depending on the application situation, because it has an insufficient effect on specific plant diseases or its residual effectiveness lasts for a relatively short period of time. As a result, the range of fungal diseases and fungi that can be controlled and treated by acylamino acid fungicides is limited. In view of the above, developing a fungicidal combination that exhibits no cross-resistance to the existing fungicidal agents, no toxicity issues and little negative impact on the environment, while improving rainfastness and reducing pest resistance is extremely difficult.
Apart from the synergistic effect and increased bio-efficacy, it is also important to have a crop solution that entrusts resistance management -which frequently results in multiple pesticides due to repeated spray rounds during the single crop cycle, and to draw the dose optimization and cost per hectare (ha).
Various prior arts have offered various fungicidal compositions useful for protecting the plant from damage by harmful pests. Some of such prior arts are indicated below:
US20180160684, dislcoses a fungicide composition containing, as active ingredients, (a) Valifenalate or a salt thereof and (b) at least one fungicide selected from the group consisting of Isofetamid, Pyriofenone, and azole-based compounds; and a method for controlling a plant disease, which includes applying the fungicide composition to a plant or soil.
IN202034023458, discloses a fungicide composition comprising a multi-site fungicide for controlling phytopathogenic fungi in plant. Further it relates to use of said composition for the
controlling fungal infection and a method for the prevention and/or treatment of fungal leaf spot diseases caused by Zymoseptoria infection in plants.
EP2854547B1 discloses a composition comprising at least one biological control agent selected from specific microorganisms and at least one fungicide (I) which is Trifloxystrobin in a synergistically effective amount useful for reducing overall damage of plants and plant parts.
US2021007355A1, discloses combination of fungicides comprising at least one azole fungicides with other agro-chemically fungicides for controlling a broad spectrum of fungal diseases.
CN108353921A, discloses a kind of bactericidal composition including Valifenalate and Fenpyrazamine, the weight ratio of two kinds of active ingredient is 1- 40 : 40-1, the weight percentage of active ingredient is 1- 90% in fungicide, preferably 5- 80%, remaining is the auxiliary agent and carrier that allow in pesticide.
Fungicidal combinations have significant advantages over individual applications including improved and extended fungal control, lower fungicide application rates and costs, shorter contact times for improved results, less stringent use restrictions, improved selectivity, broader spectrum of fungi controlled, lower cost and fewer residue problems. However, determining appropriate fungicide application rates and combinations ratio is critical for disease control efficacy. There have been no studies to determine the most-effective and synergistic ratios of fungicides selected from acylamino acid class, at least one compound selected from strobilurin fungicide, and at least one compound selected from azole-fungicide, at which ratio these fungicides synergistically complement each other's fungicidal properties not seen at other ratios. Thus there exists a need in the art for a synergistic fungicidal composition comprising such fungicides.
Valifenalate, IUPAC name: methyl (3RS)-3-(4-chlorophenyl)-N-[N-(isopropoxycarbonyl)-L-valyl]-P-alaninate, anti-peronosporic fungicide, belonging to the group of Carboxylic acid (CAA) Amides, with strong systemic activity. Valifenalate belongs to acylamino acid class of fungicides. Fungi belonging to Oomycetes like Plasmopara viticola (grapevine), Phytotphthora infestans (potato and tomato), Peronosoora destructor (onion), PseudooeronosDora cubensis
(cucurbits), Bremia lactucae (lettuce and similar) are the exclusive target of Valifenalate (Valis). Valifenalate acts by inhibiting the cell metabolism and particularly the synthesis of the fungal cell wall. Particularly, it is an anti-peronosporic fungicide which is used to control mildew in many crops including grapes, potatoes and tomatoes.

Strobilurin fungicides are globally used to combat white mold, rot, early and late leaf spot, rusts and rice blast (Bartett et al., 2001; FAO Meeting, 2008). Mushrooms (Basidiomycetes) are natural sources of strobilurins, and the first natural strobilurin compound, Strobilurin-A, was originally isolated from the mushroom Strobilurus tenacellus by Anke et al. (1977). Examples of strobilurin fungicides, include Azoxystrobin, Pyraclostrobin, Fluoxastrobin, Kresoxim-methyl, Trifloxystrobin, Picoxystrobin, Mandestrobin, and Metominostrobin, which have been developed and marketed (Rodrigues et al., 2013; Khandelwal et al., 2014). Strobilurin fungicides are also referred as Qol (Quinine outside inhibition) fungicides because of their unique mechanism of action. They specifically bind to the quinol oxidation (Qo) site of cytochrome b to inhibit mitochondrial respiration. This binding blocks electron transfer between cytochrome b and cytochrome cl and inhibits the synthesis of nicotinamide adenine dinucleotide (NADH) oxidation and the mitochondrial membrane protein adenosine triphosphate (ATP). In particular, strobilurin fungicides work by inhibiting the fungi's ability to undergo normal respiration.

Trifloxystrobin in particular is an Oximino- acetate fungicide with target site code C-3 and is classified as QoI-(quinone Outside inhibition) fungicide. Strobilurin fungicides have a broad spectrum of fungicidal activity, are cost effective, and degrade rapidly during plant metabolism. Such fungicides provide long-lasting, weather-protected disease control with high rainfastness.
Strobilurin fungicides are broad-spectrum with rapid and highly efficient fungicidal activities, cost effective and rapidly degrade during plant metabolism. Such fungicides provide long, lasting, weather, protected disease control having superior rainfastness capabilities.Strobilurin fungicides are effective in controlling variety of fungi and pests including control of Leptosphaerulina and Curvularia species.
Azole pesticide derivatives represent the most important category of fungicides that have excellent protective, curative and eradicant power towards a wide spectrum of crop diseases. The fungicide group, demethylation inhibitors (DMI), which contain the triazole fungicides,
was introduced in the mid-1970s. These fungicides are highly effective against many different fungal diseases, especially powdery mildews, rusts, and many leaf-spotting fungi. Various triazole fungicides are known in the art. Chemical structure of some of such fungicides are provided below:

Additionally, the fungicide composition of the present invention may be used in combination with other agricultural chemicals, for example, a fungicide, an insecticide, a miticide, a nematicide, a soil pesticide, an antivirus agent, an attractant, an herbicide, and a plant growth regulating agent. In this case, a further excellent effect may be exhibited.
Example 13
Evaluation of synergistic effect of the fungicidal composition of the present invention:
Evaluation of the synergistic effect of the composition comprising, Trifloxystrobin, Valifenalate and Difenoconazole prepared by the process described in the above examples.
Synergism can be calculated by using the Colby's method i.e. the expected (or predicted) response of the combination is calculated by taking the product of the observed response for
each individual component of the combination when applied alone divided by 100 and subtracting this value from the sum of observed response for each component when applied alone. Synergism of the combination is then determined by comparing the observed response of the combination to the expected (or predicted) response as calculated from the observed response of each individual component alone. If the observed response of the combination is greater than the expected (or predicted) response, then the combination is said to be synergistic and falls within the definition of synergistic effect. (Colby, S. R., Weeds, 1967(15), p. 20-22).
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 (Trifloxystrobin) at a defined dose (equal to x).
Y is the percentage of pesticidal control observed by the compound (Valifenalate) at a defined dose (equal to y).
Z is the percentage of pesticidal control observed by the compound (Difenoconazole) 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.

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.
Evaluation of the present composition on tomato crop:
Field experiment for synergistic activity of Trifloxystrobin, Valifenalate and Difenoconazole for the control of early blight (caused by Alternaria solani) and late blight (caused by Phytophthora infestans) diseases in tomato crop were conducted at farmer field, Sonipat (Haryana).
To evaluate the synergistic effect, tomato (Variety: Pusa Rubi) crop was sown in 4 m x 5 m plots maintaining 30 cm x 30 cm plant distance with three replications and in Randomized Block Design (RBD) during July to October, 2021. The treatments were applied as foliar spray in the form of SC formulation @ 250 ml/ha on initiation of disease incidence and repeat applied at 15 days' interval. The active components were applied at 2-3 doses in different ternary and binary combinations. Solo components were also taken for comparison. The treatment details are as under:

It is clearly evident from the data shown in above Table 1 for per cent early blight disease control and per cent late blight disease control in tomato crop that the ternary composition of the present invention comprising Trifloxystrobin, Valifenalate and Difenoconazole Tl to T5 are highly synergistic for both the diseases control with > 1 Colby's Ratio. The binary combination of two fungicides Trifloxystrobin + Valifenalate (T6 to T10), Trifloxystrobin + Difenoconazole (Tl 1 to T15), and Valifenalate + Difenoconazole (T16 to T20) are compatible
but synergistic effect shown is low for the control of both the diseases as compared to ternary combination of Trifloxystrobin, Valifenalate and Difenoconazole.

Based on the data recorded per cent disease index (PDI) was calculated. The per cent reduction in disease incidence was also calculated over control. The crop yield was recorded at each harvest and cumulative yield has been expressed as q/ha. The observations for phytotoxicity symptoms on tomato crop at 1, 3, 7 and 10 days after each spray were also recorded. Based on treatment application cost, market price of produce and net profit, the Cost: Benefit Ratio was calculated for the economics of ternary combination treatments. The data were subjected to statistically analysis of variance. Results are presented in Tables 2, 3 and 4.
Results:
The results for early blight and late blight disease incidence on tomato crop recorded during the experimental period and per cent reduction in disease incidence over untreated control are summarized in Table 2 and 3. The data on yield is presented in Table 4. The observations recorded for phytotoxicity symptom is presented in Table 5.

From the above examples, it can be clearly seen that the composition of the present invention is superior for controlling the early blight and late blight diseases at 10 days after each spray (Table 2 and 3) in tomato crop as compared to the binary composition and solo component comprising Trifloxystrobin 10% SC, Valifenalate 20% SC and Difenoconazole 25% EC at different dosage levels. Other registered products available in the market, Tebuconazole 50% + Trifloxystrobin 25% WG, and Azoxystrobin 18.2% + Difenoconazole 11.4% SC, evaluated were next in order of effectiveness after ternary combination products.
The yield of tomato fruit also improved in the ternary combination of Trifloxystrobin 10% + Valifenalate 20% + Difenoconazole 12.5% SC as compared to binary and solo components (Table 4). One of the reasons of higher crop yield may be due to better control of diseases. The
Cost: Benefit Ratio revealed that ternary combination Trifloxystrobin 10% + Valifenalate 20% + Difenoconazole 12.5% SC @ 500 ml/ha and 625 ml/ha were most economical with higher Cost: Benefit Ratio as compared to other binary and solo treatments (Table 4).
The composition Trifloxystrobin 10% + Valifenalate 20% + Difenoconazole 12.5% SC @ 400, 500, 625 and 1000 ml/ha, further showed no phytotoxicity in the tomato crop after 1, 3, 7 and 10 days after each spray (Table 5).
It is evident from the above tables that the composition of the present invention resulted in efficient control of early blight and late blight diseases with higher yield as compared to the reference standard products (binary compositions and solo products). The Cost: Benefit Ratio also showed that ternary composition of the present invention was most economical with higher Cost: Benefit Ratio as compared to other binary and solo treatments. Further, the composition of present invention is resulted synergistic.
