CROSS REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application Ser. No. 61/799,526, filed Mar. 15, 2013, the content of which is incorporated by reference in its entirety.

FIELD

The disclosure provides for compounds, compositions, and methods of reducing dust, for example seed dust, by utilizing a dust reducing composition described herein. The disclosure also provides for methods of reducing seed dust associated with the treatment, coating, processing, transportation, storage, and/or planting of seeds by treating a seed with a composition described herein. Methods and compositions for improving the homogeneity and dispersion of an active agent on a seed surface are also provided. The disclosure also provides for methods of treating or washing a seed prior, during the same time as, or after treatment of a seed with a seed treating agent. Seeds and compositions useful in these methods are also described.

BACKGROUND

There is a need to develop new techniques for reducing and/or mitigating the amount of seed dust associated with the treatment, coating, and planting of seeds. Depending on the type of seed coating or treatment employed, seed dust can accumulate during a variety of situations associated with the processing, shipping, and/or planting of seeds. For instance, in situations where seeds are pre-treated with a coating agent or composition, placed into bags and shipped to a location, seed dust can accumulate in seed bags due to seed-to-seed and/or seed-to-bag interactions. Seed dust can also accumulate during the storage or handling of seed or seed bags. As such, there is a need to find an alternative to traditional seed coatings that are capable of limiting dust associated with the treating, coating, planting, and/or shipping of seeds. To this end, the disclosed compositions and methods have the ability to reduce and mitigate seed dust in a manner that was not previously recognized.

In yet another aspect, a composition described herein is applied in one, two, three or more application steps to a seed. In another aspect, a method described herein excludes multiple application steps. In an aspect, the methods described herein include a first sequential application of a treating agent described herein to a seed followed by a second application of lubricant composition described herein to a seed.
Seeds which can be treated by the methods described herein include, for example, seeds that are treated with insecticides, pesticides, or fungicides that are harmful to pests or insects, for example, bees. Seeds may include any agricultural or vegetable seeds that are planted through a vacuum planter, including wherein talc may be used as a planter lubricant. In an aspect, the seed is selected from the group consisting of a corn seed, cotton seed, sorghum seed, oat seed, rye seed, rice seed, rapeseed, canola seed, barley seed, soybean seed, or vegetable seed. In an aspect, the seed is corn seed. Examples of wheat seeds include, for example, Found Boundary, Bullet, or Oaks wheat varieties. Examples of corn seeds capable of being used in the methods described herein include, for instance, sweet corn (for example, zea mays convar. saccharata var. Rugosa), silver queen corn, golden bantam, early sunglow, indian corn, sugar corn, pole corn, field corn, dent corn, flint corn, flour corn, blue corn (for example, Zea mays amylacea), pop corn, and waxy corn.

The method of treatment according to the invention can be used in the treatment of genetically modified organisms (GMOs), e.g. plants or seeds. Genetically modified plants (or transgenic plants) are plants of which a heterologous gene has been stably integrated into genome. The expression “heterologous gene” essentially means a gene which is provided or assembled outside the plant and when introduced in the nuclear, chloroplastic or mitochondrial genome gives the transformed plant new or improved agronomic or other properties by expressing a protein or polypeptide of interest or by downregulating or silencing other gene(s) which are present in the plant (using for example, antisense technology, cosuppression technology or RNA interference—RNAi-technology). A heterologous gene that is located in the genome is also called a transgene. A transgene that is defined by its particular location in the plant genome is called a transformation or transgenic event.
Seeds may be treated with the described compositions by applying the compositions directly to the seed. In another embodiment, the seed may be treated indirectly, for example by treating the environment or habitat in which the seed is exposed to. Conventional treatment methods may be used to treat the environment or habitat including dipping, spraying, fumigating, chemigating, fogging, scattering, brushing on, shanking or injecting.

Example 8

Example 8 sets forth the impact of particle size of the active ingredient on dust levels.
As can be seen, there is a direct correlation between particle size and dust levels. As active ingredient particle size increases, the amount of dust on the seed increases.

Example 9

Example 9 sets forth an analysis of surface coverage of the tested formulations and dust level.
Wheat or corn seeds are treated with the seed treatment composition (slurry) by a Hege seed treatment device, where the slurry is atomized and coat the seeds uniformly.
The treated seeds are kept open to ambient environment for 5 days and then stored in a constant climate chamber for minimum of 48 hours at 20° C.±2° C. and 50%±10% relative humidity. The amount of dust coming off the seeds is measured using a Heubach dustmeter. About 100 grams of treated seeds are placed in a chamber. The chamber is rotated to generate friction among the seeds and between the chamber wall and the seeds, which simulate the handling of the treated seeds. A constant airflow passes through the chamber controlled by a precision vacuum system. The flow of air carries air borne particles through a coarse filter separator onto a glass fiber filter disc. The Heubach dust values can be calculated by measuring the weight of filter disc before and after the evaluation test.
A qualitative assessment of seed coating using microscopic imaging was conducted.
Treated seeds with lower level of dust have a higher percentage of surface coverage of formulation with both ridges and valleys covered.
