Patent Application
20180020668
The present invention is generally directed to agricultural mixtures comprising 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide, ethaboxam, and metalaxyl, and methods of use thereof.
Seed rot, seedling decay (damping-off), and seedling disease can reduce plant emergence and decrease yields. These blights are caused by a number of pathogens. Unfortunately, contemporary agronomic practices are exacerbating the problem. The current trend towards early planting in cold, wet soils, reduced tillage or no-till fields favors an environment conducive to the pathogen growth over the growth and development of the planted seed.
Seed treatments are an efficient method used to control pathogens as the actives are applied directly to the seed and are present on the seed and in the seed zone, protecting the germinating seed and seedling during early growth and development. Seed treatments are applied prior to planting. It is important to utilize approved commercial, recently calibrated, seed treatment equipment to insure excellent seed coverage and uniformity over the seed-coats. This method of application requires seed treating personnel to use and safely operate seed treatment equipment. Providing pre-treated seeds to end users is an economical alternative to drench, in-furrow, or foliar applications of seed or plant protection products.
The widespread use of foliar fungicides has resulted in a build-up of resistance in the pathogens. Accordingly, the effectiveness of presently used fungicides is diminishing if they are applied alone.
Solo fungicide applications used frequently and without alternating or mixing with fungicides of different modes of action has led to pathogen resistance. For example, Phytophthora and downy mildew fungi have shown resistance to metalaxyl. Rhizoctonia has shown resistance to azoxystrobin. Pathogen resistance is a major concern because it can cause sudden crop failures resulting in severe reductions in crop yields.
U.S. Pat. No. 7,598,395 B2 describes agricultural compositions comprising the succinate dehydrogenase inhibitor (“SDHI”) isopyrazam, 3-difluoromethyl-1-methyl-1H-pyrazole-4-carboxylic acid (9-isopropyl-1,2,3,4-tetrahydro-1,4-methano-naphthalen-5-yl)-amide (available from Syngenta). U.S. Pat. No. 7,538,073 B2 is directed to pyrazolylcarboxanilides including penflufen, N-[2-(1,3-dimethylbutyl)phenyl]-5-fluoro-1,3-dimethyl-1H-pyrazole-4-carboxamide (available from Bayer CropScience LP). Sedaxane, N-[2-[1,1′-bicyclopropyl]-2-ylphenyl]-3-(difluoromethyl)-1-methyl-1H-pyrazole-4-carboxamide is another commercially available SDHI (Vibrance™, also available from Syngenta). WO Application No. 2006/087343 discloses another SDHI, fluxapyroxad, 3-(difluoromethyl)-1-methyl-N-(3′,4′,5′-trifluoro[1,1′-biphenyl]-2-yl)-1H-pyrazole-4-carboxamide (available from BASF). While it is known that these SDHIs have fungicidal activity, their activity is not always acceptable for some applications. Further, the commercially available SDHIs do not provide broad spectrum coverage, meaning they do not provide protection from several different types of fungi.
Accordingly, there is a need in the art for effective pesticidal seed treatments, especially fungicidal treatments. The seed treatments should have broad spectrum activity to protect the seed and seedlings from the diverse fungal pathogens present in the soil, which discourage pesticide resistance or tolerance, have little-to-no phytotoxicity, and should be safe and easy for the seed treat applicator and end user.

A study was conducted in order to determine the effects of 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide mixtures on corn plant stand, vigor and the effects of pest infestation. The formulated actives were tank mixed in a seed treatment slurry. An aliquot of the tank mix was applied to seeds using a Hege 11 treater (manufactured by Winterstieger GmbH). The tank mix was injected through a nozzle or onto a rotating disk that atomizes the formulation and applies it to the seeds. The seeds fall into or flow into a rotating drum. The rotation spreads and then dries the formulation on the seeds.
Two separate trials/plantings were completed in April about two weeks apart. Randomized block design was used and the field was inoculated with Rhizoctonia. Emergence is the number of plants per acre, vigor was rated on a scale of 1 to 9, pest severity was the percentage of infected plants, and pest incidence was rated on a scale of 1 to 9. The plant emergence, vigor, pest severity and pest incidence were taken about 30 DAP. Final yield was taken about six months after planting. The results of these studies can be seen below in Tables 1A and 1B.
There was no phytotoxicity observed during this study by any of the treatments. This study illustrates that 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide mixture treatments provide healthier plants than other treatments.
The mixtures of the present invention also provided dramatic increases in yield. This allows for more corn to be produced from the same amount of land.
A study was conducted in order to determine the effects of seed treatments on the number of corn plants per acre and yield. One acre was planted with seeds treated as indicated below in a randomized block design. Treatments were applied to the seeds in a manner known by those of skill in the art. The number of plants was determined for each treatment on four different days before harvest. After harvest, the yield of the plants was determined. The results of this study can be seen below in Tables 2 and 3.
This study illustrates a 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide mixture with metconazole, ethaboxam, metalaxyl, and thiamethoxam provides better stand than the commercial standard four-way mixture with an insecticidal control (compare Treatment 6 with Treatment 3). 3-(Difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide mixtures also lead to higher yields. Thiamethoxam does not have activity against fungal pathogens.
Another study was conducted in order to determine the effects of seed treatments on the number of corn plants per acre and yield. The study design was the same as the study described in Example 1. The results of this study can be seen below in Tables 3 and 4.
This study illustrates that a mixture of 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide with ethab oxam, metalaxyl, and thiamethoxam (Treatment 5) provides increased stand. The addition of metconazole or mandestrobin further increases stand (Treatments 6 and 7). However, if both metconazole and mandestrobin are added to Treatment 5, no additional increase is seen over Treatment 5 (Treatment 8). Regarding yield, 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide mixed with metconazole resulted in the greatest increases (Treatment 6 with 184 bushels and Treatment 8 with 180 bushels compared to insecticide check with 172 bushels and commercial standard with 173 bushels).
A study was conducted in order to determine the effects of seed treatments on the vigor and health of soybean plants, percentage of pest infestation, and yield. Treatments were applied to the seeds in a manner known by those of skill in the art. Pest incidence is percent of the plants infected with Fusarium. The results of this study can be seen below in Table 6.
This study illustrates that a 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide mixture treatment increases plant height and yield compared to the untreated control and commercial standard (for example, compare Treatment 6 with the commercial standard Treatment 2).
A study was conducted to determine the effect seed treatments had on rice yield. The rice was inoculated with Rhizoctonia in a manner to provide extreme disease pressure on the crop. The results of this study can be seen below in Table 9.
As illustrated by Table 9, the mixtures containing 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide provided at least twice the yield (2.8 for Treatment 5 and 3.3 for Treatment 6) as the commercial standard, Treatment 4. The addition of fludioxonil to 3-(difluoromethyl)-1-methyl-N-[(3R)-1,1,3-trimethyl-2,3-dihydroinden-4-yl]pyrazole-4-carboxamide provides a broader spectrum of activity with the addition of Fusarium protection.
