The present disclosure relates to agrochemical combinations for the control of plant pests. More particularly, the present disclosure relates to novel combinations, compositions comprising these combinations and methods of using the combinations and compositions for the treatment of plant propagation materials.
Combinations of insecticides and fungicides are often used to broaden the spectrum of control of insect and fungal pests, and to reduce dosage, thereby reducing environmental impact, and decreasing the chances of developing resistance. The combination of insecticides and fungicides at times demonstrates an additive or synergistic effect that results in an improved control of the pests.
Damage to seeds from insect and fungal pests is a major concern for the agriculturalist. There are various diseases such as seed rot which reduce germination rates and cause considerable decrease in yield. Treating the seeds with insecticides and/or fungicides can help reduce damage caused by soil pests. Additional potential advantages of treating seeds or other plant propagation materials are improvements in germination rates, increased yield, and improved plant health.
There are many combinations of insecticides and fungicides known in the art for the control of soil borne pests. U.S. Pat. No. 7,732,374B2 teaches a combination of prothioconazole and a specific insecticide selected from fipronil, chlorpyrifos or thiamethoxam for the control of pests in seeds, soils, and the like.
Using the same compositions over a long period of time can result in resistance to certain pests. There is thus a need in the art for novel combinations of actives that decrease the chances of resistance and improve the spectrum of disease and pest control.
One objective of the present disclosure is to provide improved combinations of insecticides and fungicides for the control of soil borne pests.
Another objective of the present disclosure is to provide a method and a composition for controlling insect pests and fungal diseases by treating plant propagation material.
Yet another objective of the present disclosure is to provide improved combinations of insecticides and fungicides that promote plant health.
Embodiments of the present disclosure can ameliorate one or more of the above mentioned problems.
In an aspect, the present disclosure provides a combination of azoxystrobin; at least one benzimidazole fungicide; and at least one neonicotinoid insecticide; wherein the combination does not contain fipronil.
Another aspect of the present disclosure provides a method of improving yield in crops, the method comprising applying to a plant propagation material of a crop, a combination comprising azoxystrobin; at least one benzimidazole fungicide; and at least one neonicotinoid insecticide; wherein the combination does not contain fipronil.
Yet another aspect of the present disclosure provides a method of improving plant health, the method comprising applying to a plant propagation material of a crop a combination comprising azoxystrobin; at least one benzimidazole fungicide; and at least one neonicotinoid insecticide; wherein the combination does not contain fipronil.
Another aspect of the present disclosure provides a composition for treating a plant propagation material, the composition comprising azoxystrobin; at least one benzimidazole fungicide; at least one neonicotinoid insecticide; and an agrochemical adjuvant; wherein the composition does not contain fipronil.
In another aspect, the present disclosure provides a method of controlling pests by treating a plant propagation material with a composition comprising azoxystrobin; at least one benzimidazole fungicide; at least one neonicotinoid insecticide; and an agrochemical adjuvant; wherein the composition does not contain fipronil.
In yet another aspect, the present disclosure provides a method for improving plant health, the method comprising applying to a plant propagation material of a crop plant a combination comprising azoxystrobin; at least one benzimidazole fungicide; at least one neonicotinoid insecticide; and an agrochemical adjuvant; wherein the composition does not contain fipronil.
The term “plant propagation material” refers to the parts of the plant, such as seeds, which can be used for the propagation of the plant and vegetative plant materials such as cuttings and tubers (for example, potatoes). Plant propagation materials include the seeds (in the strict sense), roots, fruits, tubers, bulbs, rhizomes, and other parts of plants, germinated plants or young plants, which may be transplanted after germination or after emergence from the soil.
“Insecticidal” refers to the ability of a substance to increase mortality or inhibit, growth rate of insects. “Fungicidal” refers to the ability of a substance to decrease or inhibit growth of fungi. The term “agriculturally acceptable amount of active” refers to an amount of an active, for example, an insecticide or a fungicide that kills or inhibits the plant disease for which control is desired, in an amount not significantly toxic to the plant being treated. To “control” or “controlling” insects means to inhibit, through a toxic effect, the ability of insect pests to survive, grow, feed, and/or reproduce, or to limit insect-related damage or loss in crop plants, or denotes control and prevention of a disease caused by insect pests. Controlling effects of insect pests include all deviation from natural development, for example killing, retardation, decrease of the fungal disease or insect pest. To “control” insects may include killing the insects, and preferably means killing the insects.
The term “improved seed vigour” refers to seed properties that determine potential for fast and uniform emergence, and the development of seedlings under a wide range of field conditions, when compared with the same trait in a control plant which has been grown under the same conditions in the absence of the method of the disclosure. Such traits may include, early and/or improved germination, improved emergence, increased root growth, a developed root system, increased root nodulation, increased shoot growth, improvement in plant height, an increase in plant weight (fresh or dry), bigger leaf blades, greener leaf colour, increased pigment content, increased photosynthetic activity, earlier flowering, longer panicles, early grain maturity, increased seed, fruit or pod size, increased pod or ear number, increased seed number per pod or ear, increased seed mass, enhanced seed filling, delay of senescence, and improved vitality of the plant.
The present inventors found unexpected synergy when azoxystrobin is combined with a benzimidazole fungicide and a neonicotinoid insecticide, wherein the combination does not contain fipronil. More specifically, the present inventors found unexpected synergy when azoxystrobin is combined with either carbendazim or thiophanate methyl and at least one neonicotinoid insecticide, wherein the combination does not contain fipronil.
Azoxystrobin is a systemic fungicide belonging to the strobilurin class of compounds. Its mode of action is attaching to the Qo site of complex III of the mitochondrial electron transport chain, thereby preventing the production of ATP. Its chemical name is methyl (E)-2-{2-[6-(2-cyanophenoxy) pyrimidin-4-yloxy]phenyl}-3-methoxyacrylate. Complex III of the electron transport chain is also known as Q-cytochrome c oxidoreductase or simply cytochrome reductase.
Benzimidazole fungicides inhibit mitosis and cell division in fungi. They are broad spectrum fungicides and can control a wide variety of fungi.
Neonicotinoid insecticides areacetylcholine receptor (nAChR) agonists. These insecticides can control a broad spectrum of insect pests.
The present inventors have shown that the combinations of the present disclosure surprisingly result in a synergistic action. The combinations of the present disclosure allow for a broad spectrum of pest control and provide surprisingly improved plant vigour and yield.

In an aspect, the present disclosure provides methods of improving vigour or yield of the plant comprising, applying to a plant propagation material before sowing, a combination comprising:
In another aspect, the present disclosure provides methods of controlling soil borne fungi and insect pests, the method comprising, applying to a plant propagation material before sowing, a combination comprising:
In another aspect, the present disclosure provides methods for treating an unsown seed to protect the seed and/or shoots and foliage of a plant grown from the seed from damage by a pest, the method comprising contacting the unsown seed with a composition comprising azoxystrobin; ii) at least one benzimidazole fungicide selected from carbendazim or thiophanate methyl, and a combination thereof; and iii) thiamethoxam.
In another aspect, the present disclosure provides methods for treating an unsown seed to protect the seed and/or shoots and/or foliage of a plant grown from the seed from damage by a pest, the method comprising contacting the unsown seed with a composition consisting essentially of azoxystrobin; ii) at least one benzimidazole fungicide selected from carbendazim, thiophanate methyl, and a combination thereof; and iii) thiamethoxam.
In an aspect, the combinations or the compositions of the present disclosure may be presented as a kit of parts, or as a ready mix formulation that may be readily applied to the plant propagation material or may be applied to plant propagation material before being commercially vended.
Surprisingly, it has been found by the present inventors that azoxystrobin, a benzimidazole fungicide and thiamethoxam, wherein the combination does not contain fipronil, when applied individually, were ineffective in the control of soil borne fungi and insect pests but demonstrated excellent synergistic control on weeds when applied together. The combination controlled the soil borne fungi and insect pests. The combination of azoxystrobin, a benzimidazole fungicide, preferably thiophanate methyl and thiamethoxam controlled seed borne diseases such as seed rot among others. The current disclosure therefore provides advantageous methods of controlling soil borne fungal and insect pests, preferably on soybean. The present method also provides a broader spectrum of controlling such pests and helps in resistance management, thus improving germination rate and producing plants with improved vigour and a broader spectrum of control at lower use rates.
The combinations and the compositions of the present disclosure exert at least one of the following advantages:
These combinations and the compositions prevent mycelial development, spore germination and the formation of apressories and hautoria, controlling the main soil and seed pathogens such as Rhizoctonia solani and Sclerotinia sclerotiorum. The combinations and the compositions of the disclosure can thus eliminate the fungi present on the surface of the seeds and prevent germination of the spores that come after the treatment, providing a synergistic effect.
The storage time of the thus treated seeds can be greater than 120 days without interfering with the germination and vigor patterns.
The combinations and the compositions of the disclosure can be adapted to a violet color associated with the “optical brightness” providing night time brightness through black light, making it difficult to falsify the product and aiding the differentiation of grain for treated seed.
The combinations and compositions display improvement of the plant defence mechanism against pathogens. They promote the growth of the seedlings through the increment of the root system, with greater depth of roots and better utilization of nutrients. Increased photosynthetic, consequently lower energy consumption of the seedling providing vigorous growth, and conditioning the plant to achieve superior productivity even under stress conditions.
The combinations and the compositions of the disclosure can facilitate better coverage of seeds due to adherence products through a differentiated and specific formulation for the treatment of seeds, consequently less loss of active ingredient.
The plots treated with present combinations or compositions have reduced infestation for insect pests such as shoot fly, termite and white grub.
According to the present disclosure, the treatments achieve high yield and an excellent cost benefit ratio. Further, treatment with present combinations and compositions does not have any adverse effect on the growth of soybean crops or on germination of soybean crops. In addition, the treatments of the present disclosure do not have any harmful effect on the population of natural enemies present in the soybean ecosystem. Nevertheless, the present treatments do not produce any phytotoxicity effect to soybean, and it is safe to use the combinations and compositions in soybean crops for control of seed diseases and insect pests.
However, it should be understood that the scope of the present disclosure is not limited by the examples in any manner. It will be appreciated by any person skilled in this art that the present disclosure includes aforesaid examples and further can be modified and altered within the technical scope of the present disclosure.
While the foregoing written description of the disclosure enables one of ordinary skill to make and use what is considered presently to be the best mode thereof, those of ordinary skill will understand and appreciate the existence of variations, its combinations, and equivalents of the specific embodiment, method, and examples herein. The disclosure should therefore not be limited by the above described embodiment, method, and examples, but by all embodiments and methods within the scope and spirit of the disclosure.
The disclosure will be illustrated with reference to the following examples.
The required quantity of excipients was charged in vessel equipped with a stirrer and a homogenizer. The above-mentioned quantities of active ingredients were charged to the vessel with continuous agitation and homogenization.
Homogenized materials were then feed to the wet grinding mill for particle size reduction (about less than 7 (D-90) micron). The slurry was taken in to the gelling vessel for gelling process till complete gellification to obtain the formulation.
This example illustrates the efficacy of soybean seed treatment with the formulation of example 1. Experiments were carried out to study the bio efficacy of the present compositions as a seed treatment in soybean against soil and seed borne diseases. The results are recorded at 20 and 40 days after sowing (DAS) and are represented in the following tables.

From the above data it is concluded that the present composition as a seed treatment provided good control of root rot and seedling blight diseases as compared to treatments with compositions that do not contain all three of the azoxystrobin, benzimidazole fungicide, and neonicotinoid insecticide of the present compositions.
The present compositions used as a seed treatment was evaluated for efficacy against shoot fly, termite and white grub. Two season trial results indicated that plots treated with the present compositions recorded the least infestation for all three insect pests.
Further, the yield data recorded indicated that present composition treatments provided significantly higher yield as compared to treatments with compositions that comprises one but not all of the azoxystrobin, benzimidazole fungicide, and neonicotinoid insecticide of the present compositions.
The combinations or treatment compositions of the present disclosure also showed synergy after applying Colby's formula.
The present compositions do not have any adverse effect on the growth of soybean crops as or the germination of soybean crops and are safe to use in soybean crops for control of diseases and insect pests.
