The field relates to application of seed treatments.
BACKGROUNDCrop seeds that are planted for agricultural purposes are treated with a variety of seed treatment products that offer benefit from early season pests and diseases in addition to enhancing seed germination and seedling vigor. These seed treatment products include for example, fungicides, insecticides, nematicides, biologicals and other components that improve general plant health. Treatments can also include nutrients including fertilizer. Crop seeds are often treated at production plants where the seeds are routinely produced and packaged for distribution. Crop seeds are also treated at retail locations and on-farm locations where applicable. Applying seed treatment products to seeds depend on a variety of environmental factors such as temperature, humidity, atmospheric pressure and others. Over or under application of seed treatment products may result in discarding treated seeds and operational inefficiency. Such environmental factors vary across geographies and impact seed treatment applications that involve more than one seed treatment product. Therefore, controlling such environmental factors during seed treatment applications or developing formulations that work better in certain environmental conditions are desirable.

Relative humidity (RH) is generally referred to as the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at the same temperature. Relative humidity depends on temperature and the pressure of the system of interest. The relative humidity is also generally referred to the percent of saturation humidity, generally calculated in relation to saturated vapor density.
Relative Humidity (%)=(actual vapor density/saturation vapor density)*100
The common units for vapor density are g/m3.
Dew point generally refers to the temperature, at which the moisture content in the air will saturate the air. If the air is cooled further, some of the moisture will condense.
Climate control or climate controlled generally refers to the control of temperature and relative humidity, in buildings or other enclosed spaces, for a specific process including the operations of machines and materials including seed treatment components such as chemical formulations and biologicals. The terms weather, weather conditions, environment or environmental conditions may also be used to describe the climate-controlled elements of this disclosure.
Suitable ranges of relative humidity within a climate controlled enclosure or chamber include for example of about 10% to about 20%; about 20% to about 30%; about 25% to about 35%; about 30% to about 40%; about 35% to about 45%; about 40% to about 50%; about 45% to about 55%; about 50% to about 60%; about 55% to about 65%; about 60% to about 70%; about 65% to about 75%; about 70% to about 80%; about 75% to about 85%; about 80% to about 90%; and about 85% to about 95%; and any sub-ranges within these exemplified humidity levels are also suitable.

Wider temperature ranges of about plus or minus 10° C. are also suitable for operating the enclosure within a desired temperature level. Operational temperature levels in the various geographical regions can range from about 1° C. to about 45° C. depending on the treating season and location. In an embodiment, preferred temperature ranges are about 50° F. to about 70° F. (or about 10° C. to 22° C.). For example, in a production plant, the temperature level maintained within the enclosure is significantly different than the temperature level outside the enclosure, such for example within the building that houses the enclosure. In an embodiment, the temperature level within the enclosure that houses the seed treating equipment is specifically maintained at a predetermined level compared to the temperature level that is maintained in the production plant as a whole. Similarly, in a testing location for evaluating seed treatment formulations, the temperature within the enclosure is maintained at a different level to simulate the prevailing temperature levels of a target geographical location. For example, in an embodiment, the temperature level of the enclosure for a testing center in a North American location may be set to simulate the higher temperature levels of a seed treatment location in Brazil for treating soybeans during the summer season. For example, in an embodiment, the temperature level within the enclosure is maintained at a lower level in a production plant in a high temperature production location, to match the desired temperature level for the chosen seed treatment product or products for the target crop. Further, a specific biological component as part of the seed treatment recipe may require a certain humidity and temperature range for increased survivability of the microorganism present in the biological component.
One or more microprocessor-based devices are used to obtain and process data from one or more sensors and thereby control the HVAC systems to maintain a desired range of humidity and temperature in the enclosure. Such devices are programmable so that for a certain seed treatment recipe, a particular range of temperature and humidity levels are maintained automatically without specific user input to adjust the individual settings for the temperature and humidity controllers. For example, after a seed treatment recipe and crop type are input into a master computing system (e.g., a computer), the devices that modulate the climate-controlled enclosure will automatically receive instructions from the master computing system to set the temperature and humidity levels that have been previously determined to work optimal for the chosen seed treatment recipe.
In an embodiment, the climate controlled enclosure (e.g., a room or a chamber within a building) maintains a desired level of humidity and temperature independent of the humidity levels that exist inside a seed treatment equipment where the seeds are contacted with a plurality of seed treatment products.

All neonicotinoids act as agonists at the nicotinic acetylcholine receptor in the central nervous system of insects. This causes excitation of the nerves and eventual paralysis, which leads to death. Due to the mode of action of neonicotinoids, there is no cross-resistance to conventional insecticide classes such as carbamates, organophosphates, and pyrethroids. A review of the neonicotinoids is described in Pestology 2003, 27, pp 60-63; Annual Review of Entomology 2003, 48, pp 339-364; and references cited therein.
Neonicotinoids act as acute contact and stomach poisons, combine systemic properties with relatively low application rates, and are relatively nontoxic to vertebrates. There are many compounds in this group including the pyridylmethylamines such as acetamiprid and thiacloprid; nitromethylenes such as nitenpyram and nithiazine; nitroguanidines such as clothianidin, dinotefuran, imidacloprid and thiamethoxam.

The present disclosure is further illustrated in the following Examples. It should be understood that these Examples, while indicating embodiments of the invention, are given by way of illustration only. Thus, various modifications in addition to those shown and described herein will be apparent to those skilled in the art from the foregoing description. Such modifications are also intended to fall within the scope of the appended claims.
Example 1 Seed Treatment Evaluations Under Controlled Environments in a Testing CenterA seed treatment testing facility was built with a climate-controlled environmental chamber, where the humidity and temperature levels were adjusted to simulate real-world seed treating conditions. An illustration of climate-controlled chamber (also designated as an environmental chamber) is shown in
A production facility where seeds for commercial production and distribution to retail customers and growers includes an environmental chamber or a climate-controlled enclosure for treating seeds under predetermined or preselected temperature and humidity levels that appropriate for the chosen seed treatment recipe. In an embodiment, the production facility uses a continuous flow seed treater with the plurality of seed treatment products are pumped into the seed treatment equipment. In an embodiment multiple environmental chambers are used successively to treat the same batch of seeds with a plurality of products that require varying temperature and/or humidity levels. Optionally, when multiple environmental chambers are used, treated seeds from the first environmental chamber may be partially or fully dried prior to treating the same batch of seeds in the second environmental chamber.
In an embodiment, the containers having the seed treatment products may be housed within the environmental chambers or they can be stored outside the chambers and optionally at a different environment setting. The treated seeds are conveyed by a suitable conveyor system for further processing, such as, for example, drying in a seed dryer and then for loading, packaging and distribution to a grower customers.
A production facility can handle bulk seed treatment of crop seeds including for example, corn, soybean, canola, wheat, sunflower, and alfalfa seeds. Batch seed treaters are also suitable for use within the climate-controlled chambers.
Example 3 Developing Seed Treatment Formulations for Certain Environmental ConditionsA seed treatment formulation may perform better under a certain environmental condition (e.g., temperate) versus others (e.g., tropical). It is desirable to evaluate seed treatment formulations under real-world environmental conditions before commercial-level deployment of those formulations for various geographical regions that may have extreme environmental conditions. It is also desirable to evaluate the performance of a seed treatment product under a target environmental condition so that the application rate and any addition of binders/polymers can be optimized for the target environmental condition. In an embodiment, a test formulation for a seed treatment is evaluated under a variety of environmental conditions that are maintained within an environmental chamber that houses the seed treatment equipment. Addition of binders, polymers, colorants, and other parameters such as flow rate, treatment time are adjusted under predetermined ranges of varying humidity and/or temperature levels for a test formulation on a chosen seed type. Evaluation criteria include for example, flowability, plantability, tachyness, seed coating uniformity, dust-off levels, application accuracy of labeled rates and treated seed appearance.
In addition, the treated seeds can also be evaluated for stability, germination rate, bio availability of one or more seed treatment components, biological efficacy of biological components applied to the seeds (e.g., microorganisms or biologically-derived products) under environmental conditions that prevail in a targeted geographical region where the treated seeds will be stored before planting. Such environmental conditions are created within one or more environmental chambers where the temperature and humidity levels are modulated to simulate real-world storage conditions. For example, a North American seed treatment facility can have a plurality of appropriately sized environmental chambers that can maintain different temperature and humidity conditions. In an embodiment, for example, if the treated seeds are planned to be stored in a storage facility for several months, those conditions that occur over the several months within that storage facility are simulated within the chamber to evaluate the performance of the seed applied components as described herein.
