Definitions
- the present disclosure relates to an agricultural combination comprising at least one systemic fungicide and a plant health promoting additive and a composition comprising the same.
- the present disclosure further relates to a method of reducing residues or remnants of the systemic fungicide in field slurry and in agricultural produce.
- the said combination is synergistic and suitable for controlling phytopathogenic fungi.
- Tricyclazole (8-methyl-[l,2,4]triazolo[3,4-b][l,3]benzothiazole) is a systemic fungicide used globally on rice crop for treatment of seasonal rice blast disease. Tricyclazole protects plants from infection by phytopathogenic fungi by preventing penetration of the epidermis by the fungus. The compound acts by inhibiting melanisation within the appressorium, thus causing a lack of rigidity in the appressorial wall.
- the tricyclazole is from the benzothiazole chemical group that is recommended for the control of the fungus Pyricularia grisea, popularly known as rice blast, which is one of the most important diseases of rice crop.
- the tricyclazole fungicide is preventive and should be applied to rice crops before the panicles, spikelets and tillers are exposed to infection.
- Tricyclazole showed a moderate toxicity causing an increase of the genotoxic activity in rice crop water through the appearance of chromosomal alterations in roots of Allium cepa. Tricyclazole fungicides could also disrupt the function of different body organs, such as the liver, through inhibition of cytochrome CYP450 and cholesterol synthesis. While monitoring chemical contaminants in food, it was found that tricyclazole among other pesticides is frequently found even in processed white rice, par-boiled and cooked rice.
- the European Union (EU) imports 10 per cent of the rice exported by India.
- the EU has set and implemented new standards with respect to the maximum residue level (MRL) for tricyclazole used by most basmati farmers in the country, in January of 2018.
- MRL level in Basmati rice was brought down to 0.01 parts per million (ppm) from the level of 1 ppm. This action of the EU has hit the rice export and trade market in India, and the European market as well which witnessed a rapid price hike in rice sales.

Description
AGRICULTURAL COMBINATION
Technical field
The present disclosure relates to an agricultural combination comprising at least one systemic fungicide and a plant health promoting additive and a composition comprising the same. The present disclosure further relates to a method of reducing residues or remnants of the systemic fungicide in field slurry and in agricultural produce. The said combination is synergistic and suitable for controlling phytopathogenic fungi.
Background
Tricyclazole (8-methyl-[l,2,4]triazolo[3,4-b][l,3]benzothiazole) is a systemic fungicide used globally on rice crop for treatment of seasonal rice blast disease. Tricyclazole protects plants from infection by phytopathogenic fungi by preventing penetration of the epidermis by the fungus. The compound acts by inhibiting melanisation within the appressorium, thus causing a lack of rigidity in the appressorial wall. The tricyclazole is from the benzothiazole chemical group that is recommended for the control of the fungus Pyricularia grisea, popularly known as rice blast, which is one of the most important diseases of rice crop. The tricyclazole fungicide is preventive and should be applied to rice crops before the panicles, spikelets and tillers are exposed to infection.
However, there has been limited information about the transport and fate of tricyclazole in rice fields. A few studies have detected tricyclazole residues in water samples after rice harvest and have also noted that variables such as season and year are important factors in determining the distribution of tricyclazole residues. Researchers have also highlighted that there is high persistence of tricyclazole in the water - soil system, with a half-life of 4 to 17 months under laboratory conditions and 6 months under field conditions, as it is not easily hydrolysed in the environment.
Studies have further indicated that tricyclazole showed a moderate toxicity causing an increase of the genotoxic activity in rice crop water through the appearance of chromosomal alterations in roots of Allium cepa. Tricyclazole fungicides could also disrupt the function of different body organs, such as the liver, through inhibition of cytochrome CYP450 and cholesterol synthesis. While monitoring chemical contaminants in food, it was found that tricyclazole among other pesticides is frequently found even in processed white rice, par-boiled and cooked
rice. The European Union (EU) imports 10 per cent of the rice exported by India. The EU has set and implemented new standards with respect to the maximum residue level (MRL) for tricyclazole used by most basmati farmers in the country, in January of 2018. The MRL level in Basmati rice was brought down to 0.01 parts per million (ppm) from the level of 1 ppm. This action of the EU has hit the rice export and trade market in India, and the European market as well which witnessed a rapid price hike in rice sales.
Small doses of pesticide residues in field slurry or agricultural produce and their repeated contact over a period have chronic effects. Therefore, it is vital to safeguard human well-being, soil flora and environment health by selecting alternative methods in farm practices to reduce the accumulation of pesticide residues and its potentially hazardous effects.
There is a need to reduce the application of high doses of tricyclazole in crop plantations by combining tricyclazole and a plant health promoting agent, wherein the said combination augments the fungicide activity of tricyclazole with the plant health promoting agent, it is synergistic and leaves a reduced residue of tricyclazole.

By way of the present disclosure, the present inventors have successfully attempted to mitigate the issues faced with respect to residual remnants of systemic fungicides, namely tricyclazole found in agricultural field slurry, soil and even in agricultural produce of crops treated with such systemic fungicides by farmers. The presence of excessive pesticide residues negatively impacts the export prospects of crop produce in view of the restrictions imposed by regulatory authorities, ultimately damaging the economic benefit to be otherwise incurred.
The present inventors have unexpectedly found that the application of an agricultural combination comprising a systemic fungicide, namely, tricyclazole and a plant growth promoting additive, i.e. a silicic acid based plant growth promoting agent/additive significantly reduced the residue level of tricyclazole in crop plantations and in field slurry; and improved crop yield, nutrition and health of agricultural produce. The present inventors have reduced the application amount of the systemic fungicide, i.e. tricyclazole in the present agricultural combination by about 60% of the standard dosage used in agricultural applications and supplemented the said combination with a silicic acid based plant growth promoting additive. Moreover, the inventors have noted that the reduction in tricyclazole amount does not compromise the anti-fungal activity of the agricultural combination, in fact the synergistic activity of the combination becomes evident in controlling the growth and spread of phytopathogenic fungi.
Rice blast (Magnaporthe oryzae) is a key concern in achieving global food security given the disease is responsible for approximately 30% of rice production losses globally which is the equivalent of feeding 60 million people. These losses are likely to increase the global rice price and reduce consumer welfare and food security. Yield loss from blast infections depends on varietal susceptibility, the degree of infection, and the timing of fungicide application. Some yield losses associated with blast outbreaks have reached 50% or more, and the cost of mitigating those blast outbreaks via fungicide application. An outbreak of rice blast sometimes takes place in abnormal weather conditions such as low temperature or sudden rain in the summer period, thus, rice blast is one of the most serious rice diseases world-wide and development of new control strategies for blast disease are urgently required.
Moreover, an ever-increasing global demand for rice, coupled with unpredictable weather calamities in the last few years has added immense stress on rice farmers in the region. This has necessitated farmers to find new ways to grow better quality of rice in a manner that is efficient and sustainable. Moreover, the restrictions with respect to the maximum residue level (MRL) in Basmati rice has further adversely affected the production of rice.
Therefore, the present invention provides an effective and environmentally safe agricultural combination which successfully overcomes regulatory restrictions imposed and contributes to society welfare and global food security.

In an embodiment, the application is made by foliar spraying.
The rate and frequency of use of the compositions on the plant may vary within wide limits and depends on the type of use, the specific active agents, the nature of the soil, the method of application (pre- or post-emergence, etc.), the plant, the prevailing climatic conditions, and other factors governed by the method of application, the time of application and the target plant.
The method of the present disclosure offers tremendous advantages over the prior art and conventionally used methods of use of tricyclazole. The method of the present disclosure helps improves yields quality in terms of nutrition and promotes plant health and has no phyto toxicity.
The invention shall now be described with reference to the following specific examples. It should be noted that the examples appended below illustrate rather than limit the invention and that those skilled in the art will be able to design many alternative embodiments without departing from the scope of the present invention.
Examples
Example 1: Efficacy of the tricyclazole and orthosilicic acid combination
Efficacy of the tricyclazole and orthosilicic acid (OSA) combination was evaluated by determining the % disease control of Pyricularia oryzae in laboratory trials.
Protocol : The efficacy of the tricyclazole and orthosilicic acid combination treatment was initiated in laboratory experiments using Com meal agar (CMA) Medium (Hi-media) as the substrate for growth of Pyricularia oryzae fungi. CMA medium was prepared and amended by adding the concentrations of the fungicides as described in the table 1(a) below before it solidified (at 45°C). The amended medium was uniformly poured, i.e. approximately 18 ml was poured into each 90-mm Petri-plates. About 10-mm of mycelial disc was cut out from pregrown pathogen, Pyricularia oryzae, which was inoculated at the center of Petri-plate containing the medium and incubated at 27±2°C for 8-10 days. Simultaneously, a control plate without adding fungicide was set up as control. The radial growth (in mm) of mycelium was measured on the 10th days of incubation.
All the experiments were carried out in triplicates. The % fungal control/ inhibition of mycelial growth of P. oryzae over control was calculated using the following formula.
De- Dt
Per cent inhibition over control - x 100
De
Where,
De = Average diameter of fungal growth in control.
Dt = Average diameter of fungal growth in treatment.
Further, the synergy of the combination was also evaluated and the well-established method of Colby’s calculation was used to determine the synergy. A frequently used method for improving the use profile of an agricultural is the combination of an active compound with one or more other active compounds which contribute to the desired additional properties. However, when two or more active compounds are applied in combination, it is not uncommon for phenomena of physical and biological incompatibility to occur, for example insufficient stability of a joint formulation, decomposition of an active compound or antagonism of the active compounds. What is desired are, in contrast, active compound combinations having a favorable activity profile, high stability and, if possible, synergistically enhanced activity, thus permitting the application rate to be reduced, compared with the individual application of the active compounds to be combined.
Chemical mixtures can have an antagonistic effect when mixed, where the results are less than expected when the chemicals are combined. There can also be an additive effect, where the resultant mixture gives results expected from the sum of its components. Finally, there can be a synergistic effect where the results are greater than expected. A synergistic result is rare and typically only observed in results from high concentrations. In the heavily regulated
agricultural industry, high concentrations are not desirable in the environment. Therefore, when a synergistic effect is achieved at low doses, the resultant mixture is indeed a rare and unexpected finding.
A synergistic effect of an agricultural is always present when the anti-phytopathogenic activity of the active compound combinations exceeds the total of the activities of the active compounds when applied individually. The expected activity for a given combination of two active compounds can be calculated according to S. R. Colby (“Calculating Synergistic and Antagonistic Responses of Herbicide Combinations”, Weeds 15, (1967), 20-22).
This effectiveness of all treatments as measured by percent reduction in the Pyricularia oryzae., was also evaluated according to Colby’s equation as below.
If,
X is the percent inhibition of growth by tricyclazole (A) at an application rate,
Y is the percent inhibition of growth by orthosilicic acid (B) at an application rate, and
E is the expected growth as a percent of control with tricyclazole and orthosilicic acid when applying the active compounds, A and B at specific application rates as defined below.
Then,
Colby’s equation E = X + Y - XY/100
If the actual/observed anti-phytopathogenic efficacy of the tricyclazole and orthosilicic acid combination against Pyricularia oryzae exceeds the calculated value, then the activity of the combination is super additive, i.e. a synergistic effect exists. In this case, the efficacy which was observed must be greater than the value for the expected efficacy I calculated from the abovementioned formula.
Control percentage of Pyricularia oryzae (paddy blast) with the tricyclazole and orthosilicic acid combination, as well as that of tricyclazole and orthosilicic acid separately are provided in table 1 below:
Based on the observations from table 1, the present tricyclazole and orthosilicic acid combination is synergistic and showed exemplary control of the fungi. Example 2: Efficacy of tricyclazole and orthosilicic acid against leaf blast
Field trial studies were performed to evaluate the bio-efficacy and residue of the present combination of tricyclazole and orthosilicic acid (OSA) at different doses against leaf blast (Pyricularia oryzae) disease in rice. The % reduction in the amount of tricyclazole for application was also determined with reference to solo tricyclazole (i.e. treatment no. 2) as the standard dosage. The amount of actives has been provided in terms of g ai/ha in Table 2(a) and the application dose rate of the tank mix as well has been provided in Table 2(a), in terms of g/ha for tricyclazole and ml/ha for OSA. The foliar application of the present agricultural combinations was made at an interval of 10 days and were carried out in 3 replications.
At time 0, the first application of the combination of tricyclazole and orthosilicic acid is denoted as ‘A’, the application made at 10 days after application ‘A’ is designated as ‘B’ and the application made at 10 days after application ‘B’ is denoted as ‘C’. The control of leaf blast was observed at 10 days after each of the three applications, (i.e. at 10 DAA, 10 DAB and 10 DAC).

Alphabets a, b, c, d and e refer to the statistical difference between the values
The field trial studies were performed in rice plantations with the application of agricultural combinations consisting of tricyclazole and orthosilicic acid, wherein the dosage amount and rate of tricyclazole is significantly reduced compared to tricyclazole applied alone. Accordingly, it was observed that the application of the agricultural combination consisting of tricyclazole and orthosilicic acid in terms of the % control of Pyricularia oryzae was at par and even better compared to tricyclazole applied alone.
Therefore, the application of the combination consisting of tricyclazole and orthosilicic acid with reduced amount of tricyclazole is effective in controlling leaf blast in rice.
Example 3: Efficacy of tricyclazole and orthosilicic acid against rice neck blast
Field trial studies were performed to evaluate the bio-efficacy of the present combination consisting of tricyclazole and orthosilicic acid at different doses against neck blast (Pyricularia oryzae) disease in rice.
The % reduction in the amount of tricyclazole for agricultural applications was also determined with reference to solo tricyclazole (i.e. treatment no. 2) as the standard dosage. The amount of actives has been provided in terms of g ai/ha in Table 3(a) and the application dose rate of the tank mix as well has been provided in Table 3(a), in terms of g/ha for tricyclazole and ml/ha for OSA.
The foliar application of the present agricultural combinations was made at an interval of 10 days and were carried out in 3 replications. At time 0, the first application of the combination of tricyclazole and orthosilicic acid (OSA) is denoted as ‘A’, the application made at 10 days after application ‘A’ is designated as ‘B’. The % control of the diseases was observed at 20 days after the second application B, i.e. at 20 DAB.
WP: Wettable powder
Note: % reduction of the tricyclazole dose has been calculated with reference to the standard dosage of solo tricyclazole (treatment no. 2)
Alphabets a, b, c, d and e refer to the statistical difference between the values The field trial studies were performed in rice plantations to determine the reduction in neck blast diseases with the application of agricultural combinations consisting of tricyclazole and orthosilicic acid, wherein the dosage amount and rate of tricyclazole was significantly reduced compared to tricyclazole applied alone. Accordingly, it was observed that the application of the agricultural combination consisting of tricyclazole and orthosilicic acid in terms of % control of Pyricularia oryzae was better compared to tricyclazole applied alone.
Therefore, the application of the combination consisting of tricyclazole and orthosilicic acid with reduced amount of tricyclazole is effective in controlling neck blast in rice.
Example 4: Efficacy of tricyclazole and orthosilicic acid against neck blast
Field trial studies were performed to evaluate the bio-efficacy of the present combination consisting of tricyclazole and orthosilicic acid (OSA) as a tank mix at different doses against neck blast (Pyricularia oryzae) disease in rice. The % reduction in tricyclazole amounts for application was also determined. The foliar application of the present agricultural combinations was made at an interval of 10 days and were carried out in 3 replications.
The % reduction in the amount of tricyclazole for agricultural applications was also determined with reference to solo tricyclazole (i.e. treatment no. 2) as the standard dosage. The amount of actives has been provided in terms of g ai/ha in Table 4(a) and the application dose rate of the tank mix as well has been provided in Table 4(a), in terms of g/ha for tricyclazole and ml/ha for OSA.
At time 0, the first application of the combination of tricyclazole and orthosilicic acid (OSA) is denoted as ‘A’, the application made at 10 days after application ‘A’ is designated as ‘B’. The % control of the diseases was observed at 10 days after each application A, B and C, i.e. at 10 DA-A, 10 DA-B and 10 DA-C.

Alphabets a, b, c, d and e refer to the statistical difference between the values
It is evident from table 4, that a 50% reduction (treatment nos. 4 and 8) in the amount of tricyclazole compared to the standard dosage, was effective in controlling Pyricularia oryzae and the % control of the said phytopathogen was at par with the % control of the disease when solo tricyclazole at the standard dosage (treatment no.2). Similarly, at % tricyclazole reductions of 37.5%, 25% and 12.5% (treatment nos. 5, 6, 7, 9, 10 and 11) a significantly effective and enhanced control of the pathogen was observed over the standard dosage (treatment no.2).
The field trial studies were performed in rice plantations with the application of agricultural combinations consisting of tricyclazole and orthosilicic acid, wherein the dosage amount and rate of tricyclazole is significantly reduced compared to tricyclazole applied alone. Accordingly, it was observed that the application of the agricultural combination consisting of tricyclazole and orthosilicic acid in terms of the % control of Pyricularia oryzae was at par and even better compared to tricyclazole applied alone. Therefore, the present invention plays a vital role to safeguard human well-being, soil flora and environment health in farm practices and help reduce the accumulation of pesticide residues and its potentially hazardous effects.
