[0004] BACKGROUND OF THE INVENTION

[0005] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the present invention, or that any publication specifically or implicitly referenced is prior art.

[0006] Combination of insecticides and fungicides are used to broaden the control spectrum of insect and fungal pests, reduce dosage, thereby lowering environmental impact, and reduce the likelihood of resistance development. Plant, crops damage from insect and fungal pests is another major concern for agriculturalist / farmers apart from significant reduction of yields. Treating crops with combination of insecticides and fungicides helps reduce the damage caused by pests. The control of phytopathogenic fungi along with insects is of great economic importance since fungal growth and insect pests on plants or on parts of plants retards foliage, fruit or seed production, and the overall quality and yield of a cultivated crop.

[0007] Further, compositions may also be ineffective due to their ability to target only some specific types of pests and have shown resistance to other pests. On account of such resistance development, more concentrated formulations are required to be applied which results in various adverse effects on plant health and crop yield. With the onset of resistance to certain pests, there is a need in the art for a composition that decreases chances of resistance and improves the spectrum of disease and pest control with improved crop yield and plant health. The active ingredients of different mechanisms of action can be complex, some of the diseases are resistant to commonly used methods, and applications are based on the actual production of the effect. There is a need in selecting different active ingredients / agrochemically active compounds which can manifest to improve control efficiency, reducing the use of pesticides, possess broad spectrum activity and improve the germination rate, yield and plant vigour, health and are non-phy to toxic. It is always preferable to be able to reduce the amount of chemical agents released into the environment while still ensuring effective pest and disease control. Although pest control agent compositions have been studied, a high synergistic action has not always been found.

[0008] Thus, there is a need of a pesticidal compositions for fungi and insect pests control comprising of specific fungicides and insecticides which can overcome some of the aforementioned existing problems and can be prepared easily without much complex manufacturing process.

[0152] The composition of the present invention can be used to control the various pests including but not limited to Root knot nematode (Meloidogyne incognita), Loosesmut, Flag smut, Collarrot, Rootrot, Stemrot, Fruit rot, Powdery mildew, Tikka & rust, Blast, Sheath blight, Purple blotch, Anthracnose (pod blight), Leaf spot, Blast, Tikka leaf spot, Alternaria blight & Powdery mildew, Alternaria leaf spot, Anthracnose, Scab, Yellow Rust, Stem phylium blight, Die Back, Fruit rot, False smut, Dirty panicle, Cercospora leaf spot, Loose smut, Hoppers, Jassids & Thrips, Diamond Back Moth, Glume discoloration (dirty panicle), Jassid, Aphids, Thrips, Whitefly, Powdery mildew, Anthracnose (pod blight), etc.

[0153] The composition according to the invention can be applied to any and all developmental stages of pests, such as egg, larva, pupa, and adult. The pests may be controlled by contacting the target pest, its food supply, habitat, breeding ground or its locus with a bioactive amount of the present composition.

[0154] The novel composition of the present invention has very advantageous, curative, preventive and systemic pesticidal properties for protecting cultivated plants and crops. As has been mentioned, said composition of present invention is e used to inhibit or destroy the pathogens that occur on plants or parts of plants (fruit, blossoms, leaves, stems, tubers, roots) of different crops or useful plants, while at the same time those parts of plants which grow later are also protected from attack by such pathogens.

[0155] The composition of the present invention also provides control of diseases caused by a broad spectrum of fungal and insect plant pathogens preventatively or curatively by applying an effective amount of the composition either pre-or post-infection.

[0156] Plant disease control is ordinarily accomplished by applying an effective amount of a synergistic composition of the present invention either pre-or post-infection, to the portion of the plant to be protected such as the roots, stems, foliage, fruit, seeds, tubers or bulbs, or to the media (soil or sand) in which the plants to be protected are growing. The composition can also be applied to the seed to protect the seed and seedling.

[0158] Through the pesticidal composition of present invention, the number of applications to control wide range of pests appearing at the same time is minimised. The composition of present invention is highly safe to the user and to the environment. The composition offers the user a single homogenous application eliminating the need for tank mix. The composition also is cost- effective as it provides much greater simultaneous control and can be used in a variety of crops with a broader spectrum of protection.

[0256] Evaluation of synergistic effect of pesticidal composition of the present invention i.e.

[0257] Fluopyram + Tolfenpyrad + Dif enoconazole

[0258] A synergistic effect of two or more products exists whenever the action of an active ingredient composition 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.

[0259] The synergistic action expected for a given composition of two active components can be calculated as follows:

[0260] XY

[0261] E = (X + Y) - -

[0262] 100

[0263] The synergistic action expected for a given composition of three active components can be calculated as follows:

[0264] (XY+YZ+XZ) (XYZ)

[0265] E = (X + Y + Z) - - + -

[0266] 100 10000

[0267] Where:

[0268] E represents expected percentage of pesticidal control for the composition of the two or three actives ingredients at defined doses (for example equal to x, y and z, respectively).

[0269] X is the percentage of pesticidal control observed by the compound (Fluopyram) at a defined dose (equal to x). Y is the percentage of pesticidal control observed by the compound (Tolfenpyrad) at a defined dose (equal to y).

[0270] Z is the percentage of pesticidal control observed by the compound (Difenoconazole) at a defined dose (equal to z).

[0271] When the percentage of pesticidal control observed for the composition is greater than the expected percentage, there is a synergism effect.

[0272] Observed control (%) Ratio = -

[0273] Expected control (%)

[0274] Ratio of O / E > 1, synergism observed

[0275] The present invention is illustrated by way of examples, the examples are meant for illustrative purposes and should not be construed as limiting.

[0276] Experiment for Synergistic activity of composition of present invention:

[0277] Example 1- Details of experiment on Chilli crop:

[0278] Field experiment for synergistic activity of Fluopyram, Tolfenpyrad and Difenoconazole for the control of Thrips and Powdery mildew disease on chilli crop was conducted.

[0279] To evaluate the synergistic effect, Chilli (Variety: Kashi Anmol) crop was sown in 5 m x 5 m plots maintaining 45 cm x 45 cm plant distance with three replications and in Randomized Block Design (RBD). The treatments were applied as foliar application at the ETE level of insect population. Each active component was applied at recommended doses in different ternary and binary compositions. Solo compositions were also taken for comparison. The treatment details are as under:

[0280] The treatments T1 to T28 were used as foliar application whereas no treatment was done for T29 control treatment. Observations for Thrips recorded at Before spray, 7 and 15 days after sprays by observing 5 random plants per 5 leaves (2 upper 2 middle and 1 lower leaves) per plant in each replication per plot and based on number of Thrips population and reduction over control was calculated. Furthermore, the observations for Powdery mildew disease were recorded at before spray, 7 and 15 days after application by observing 5 random plants per plot and per cent disease incidence was calculated. Per cent disease incidence was calculated over control. Based on the per cent reduction in Thrips population and Powdery mildew disease the Expected control was calculated and compared with Observed control. The results of the trial have been presented here under in Table 1.

[0281] Table 1: Synergistic effect of composition of the present invention (Fluopyram + Tolfenpyrad + Dif enoconazole) against Thrips and Powdery mildew disease in Chilli crop It is clearly evident from the data shown in above Table 1 for per cent control Thrips population and Powdery mildew disease in Chilli crop that the ternary composition of the present invention comprising Fluopyram + Tolfenpyrad + Dif enoconazole T1 to T4 are synergistic for both Insect-pest and disease control with > 1 Colby’s Ratio. The binary composition of pesticides (Fluopyram + Tolfenpyrad, (Fluopyram + Difenoconazole and Tolfenpyrad + Dif enoconazole) T5 to T16 were compatible but no synergistic effect was observed for the control of thrips and powdery mildew. All solo products and market samples were also less effective for the control of both insect-pest as compared to ternary compositions of the present invention.

[0282] Experiment for Bio-efficacy evaluation of composition product of present invention:

[0283] For the ternary and binary composition based on Fluopyram, Tolfenpyrad and Difenoconazole evaluation under field conditions, the basic test composition as Fluopyram, Tolfenpyrad and Difenoconazole were manufactured specifically by the inventor. For ternary composition, Fluopyram 9.7 % + Tolfenpyrad 14.5 % + Difenoconazole 5.8% SC was used and for binary compositions, Fluopyram 9.7 % + Tolfenpyrad 14.5 % SC, Fluopyram 9.7 % + Difenoconazole 5.8% SC and Tolfenpyrad 14.5 % + Difenoconazole 5.8% SC and solo formulations of Fluopyram 9.7 % SC, Tolfenpyrad 14.5 % SC and Difenoconazole 5.8% SC were used. The market samples Fluopyram 34.48% SC, Tolfenpyrad 15 % EC and Azoxystrobin 18.2% + Difenoconazole 11.4% w / w SC were used for comparison.

[0284] Example 2: Evaluation of the composition of the present invention on Chilli crop.

[0285] The synergistic composition of the present invention Fluopyram 9.7 % + Tolfenpyrad 14.5 % + Difenoconazole 5.8% SC was evaluated on Chilli crop. The experiment plots are design in Randomized Block Design (RBD) with three replications maintaining a distance of 45 cm x 45 cm between plants and rows.

[0295] The treatments T1 to T18 and T20 were used as foliar application whereas no treatment was done for T19 untreated control plots. The treatments were applied as foliar application at the ETL level of insect population. Each active component was applied at three doses in different ternary and binary compositions. Solo components were also taken for comparison.

[0296] Observations for Thrips population were recorded at Before spray, 7 and 15 days after sprays by observing 5 random plants per 5 leaves (2 upper 2 middle and 1 lower leaf) per plant in each replication per plot and based on number thrips population and reduction over control was calculated. The observations for Powdery mildew disease were recorded at Before spray, 7 and 15 days after sprays was recorded on 5 plants per 5 leaves per plant in each replication. The green chilli yield was recorded at different picking as per harvest. The observations for phytotoxicity to Chilli crop at 0, 3, 5, 7, 10 & 15 days after spray were also recorded. Results are presented in Table 2A, 2B, 2C, and 2D.

[0302] Table 2D: Phytotoxicity evaluation of Fluopyram 9.7 % + Tolfenpyrad 14.5 % + Difenoconazole 5.8% SC on Chilli crop.

[0303] From the examples and tables above, it can be clearly seen that the composition of the present invention is superior for controlling the Thrips population at 7 and 15 days after spray (Table 2 A) and for controlling Powdery mildew disease at 7 and 15 days after spray (Table 2B) in Chilli crop as compared to the binary composition and solo compositions comprising at same dosage levels. Other registered formulated products available in the market, Fluopyram 34.48% SC, Tolfenpyrad 15% EC and Azoxystrobin 18.2% + Difenoconazole 11.4% w / w SC were also evaluated in terms of their effectiveness but observed as less effective in comparison to the ternary composition of the present invention. The yield of Chilli crop also improved in relation to the ternary composition of present invention as compared to binary and solo compositions (Table 2C).

[0304] The disclosed exemplary composition of present invention i.e. Fluopyram 9.7 % + Tolfenpyrad 14.5 % + Difenoconazole 5.8% SC @ 750 ml, 1000 ml and 2000 ml / ha further showed no phytotoxicity in the Chilli crop even after 0, 3, 5, 7, 10 and 15 days after spray (Table 2D). Evaluation of synergistic effect of pesticidal composition of the present invention i.e.

[0305] Fluopyram + Tolfenpyrad + Tebuconazole

[0306] A synergistic effect of two or more products exists whenever the action of an active ingredient composition 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.

[0307] The synergistic action expected for a given composition of two active components can be calculated as follows:

[0308] XY

[0309] E = (X + Y) - -

[0310] 100

[0311] The synergistic action expected for a given composition of three active components can be calculated as follows:

[0312] (XY+YZ+XZ) (XYZ)

[0313] E = (X + Y + Z) - - + -

[0314] 100 10000

[0315] Where:

[0316] E represents expected percentage of pesticidal control for the composition of the two or three actives ingredients at defined doses (for example equal to x, y and z, respectively).

[0317] X is the percentage of pesticidal control observed by the compound (Fluopyram) at a defined dose (equal to x).

[0318] Y is the percentage of pesticidal control observed by the compound (Tolfenpyrad) at a defined dose (equal to y).

[0319] Z is the percentage of pesticidal control observed by the compound (Tebuconazole) at a defined dose (equal to z).

[0320] When the percentage of pesticidal control observed for the composition is greater than the expected percentage, there is a synergism effect.

[0321] Observed control (%)

[0322] Ratio = -

[0323] Expected control (%)

[0324] Ratio of O / E > 1, synergism observed

[0325] 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:

[0326] Example 3- Details of experiment on Chilli crop:

[0327] Field experiment for synergistic activity of Fluopyram, Tolfenpyrad and Tebuconazole for the control of Aphids and Powdery mildew disease on chilli crop was conducted. To evaluate the synergistic effect, Chilli (Variety: Kashi Anmol) crop was sown in 5 m x 5 m plots maintaining 45 cm x 45 cm plant distance with three replications and in Randomized Block Design (RBD). The treatments were applied as foliar application at the ETL level of insect population. Each active component was applied at recommended doses in different ternary and binary compositions. Solo compositions were also taken for comparison. The treatment details are as under: The treatments T1 to T28 were used as foliar application whereas no treatment was done for T29 control treatment. Observations for Aphids were recorded at Before spray, 7 and 15 days after sprays by observing 5 random plants per 5 leaves (2 upper 2 middle and 1 lower leaves) per plant in each replication per plot and based on number of aphids population and reduction over control was calculated. Furthermore, the observations for Powdery mildew disease were recorded at before spray, 7 and 15 days after application by observing 5 random plants per plot and per cent disease incidence was calculated. The per cent disease incidence was calculated over control. Based on the per cent reduction in Aphids population and Powdery mildew disease the Expected control was calculated and compared with Observed control. The results of the trial have been presented here under in Table 3.

[0328] Table 3: Synergistic effect of composition product of the present invention (Fluopyram + Tolfenpyrad + Tebuconazole) against Aphids and Powdery mildew disease in Chilli crop

[0329] It is clearly evident from the data shown in above Table 1 for per cent control Aphids population and Powdery mildew disease in Chilli crop that the ternary composition of the present invention comprising Fluopyram + Tolfenpyrad + Tebuconazole T1 to T4 are synergistic for both Insect-pest and disease control with > 1 Colby’s Ratio. The binary composition of pesticides (Fluopyram + Tolfenpyrad, Fluopyram + Tebuconazole and Tolfenpyrad + Tebuconazole) T5 to T16 were compatible but no synergistic effect was observed for the control of aphids and powdery mildew. All solo products and market samples were also less effective for the control of both insect-pest as compared to ternary compositions of the present invention.

[0330] Experiment for Bio-efficacy evaluation of composition of present invention:

[0331] For ternary composition, Fluopyram 9.7 % + Tolfenpyrad 14.5 % + Tebuconazole 11% SC was used and for binary compositions, Fluopyram 9.7 % + Tolfenpyrad 14.5 % SC, Fluopyram 9.7 % + Tebuconazole 11% SC and Tolfenpyrad 14.5 % + Tebuconazole 11% SC and solo formulations of Fluopyram 9.7 % SC, Tolfenpyrad 14.5 % SC and Tebuconazole 11% SC were used. The market samples Fluopyraml7.7% +Tebuconazole 17.7% SC, Tolfenpyrad 15 % EC and Tebuconazole 38.39% SC were used for comparison.

[0332] Example 4: Evaluation of the composition of the present invention on Chilli crop.

[0333] The synergistic composition of the present invention Fluopyram 9.7 % + Tolfenpyrad 14.5 % + Tebuconazole 11% SC was evaluated on Chilli crop variety Kashi Anmol. The experiment plots are design in Randomized Block Design (RBD) with three replications maintaining a distance of 45 cm x 45 cm between plants and rows.

[0340] Treatment details:

[0341] Methodology:

[0342] The treatments T1 to T18 and T20 were used as foliar application whereas no treatment was done for T19 untreated control plots. The treatments were applied as foliar application at the ETL level of insect population. Each active component was applied at three doses in different ternary and binary compositions. Solo compositions were also taken for comparison.

[0343] Observations for Aphids population were recorded at Before spray, 7 and 15 days after sprays by observing 5 random plants per 5 leaves (2 upper 2 middle and 1 lower leaf) per plant in each replication per plot and based on aphid population and reduction over control was calculated. The observations for Powdery mildew disease were recorded at Before spray, 7 and 15 days after sprays was recorded on 5 plants per 5 leaves per plant in each replication. The green chilli yield was recorded at different picking as per harvest. The observations for phytotoxicity to Chilli crop at 0, 3, 5, 7, 10 & 15 days after spray were also recorded. The data were subjected to statistically analysis of variance. Results are presented in Table 4A, 4B, 4C, and 4D. Results:
