Definitions

  • the present invention relates to a liquid composition for coating plant seeds and propagules, a process for making film-forming liquid compositions, a process and apparatus for coating liquid compositions onto plant seeds and propagules and to coated seeds and propagules.
  • Seeding which is the beginning stage of the agronomist production cycle, involves placing a plant seed or a propagule directly in a field or placing a plant seed or a propagule in a nursery and then transferring to a field. Direct seeding in a field can expose the seed to a number of potential adverse factors. These factors include injury to the seed from the sowing process itself, washing away of the seed upon rainfall or watering, being eaten by animals, and partial premature germination.
  • One of the countermeasures which developed in the art was the coating and/or encapsulating of the unprotected seed utilizing various agents and techniques. Some of these coating agents include clays or analogous materials of clay minerals, and any of several derivatives of alginic acid (e.g. calcium, sodium or potassium salts or propylene glycol alginate).
  • alginic acid e.g. calcium, sodium or potassium salts or propylene glycol alginate
  • the currently employed methods for commercial coating of potatoes is by spraying powder or liquid onto potatoes as potatoes are passed through on rollers.
  • the coating applied in this manner adheres to only about 35 to 60% of the surface area of the potatoes.
  • most of sugarbeet seed is pelleted before being planted.
  • the pellet material is often blended with active ingredients such as Gaucho and Thiram.
  • the pellets are expensive to produce and oversized seeds are wasted in the process.
  • the pellets are generally brittle and many pellets break down during planting.

  • the coating compositions of the present invention have been found to be film-forming, i.e., upon contacting with seeds or propagules they form a thin liquid film that adheres to the surface. Moreover, the coating composition of the present invention can be efficiently and inexpensively applied at slightly above ambient conditions (i.e., 35°C or higher but below temperatures that damage the seed or other propagule).
  • the liquid coating of the present invention includes gelatin, a desiccant and water.
  • the coating preferably also includes active ingredients which enhance plant growth and/or protect the seed, other propagule or the resulting plant from pests, fungi and other perils.
  • the liquid coating of the present invention can be applied by any suitable apparatus but it is preferably applied to seeds using an electrostatic coating system, a conveyor steeping system or an auger steeping system, constructed in accordance with the present invention.
  • the seeds or other propagule coated in accordance of the present invention are easier to plant and they do not partially germinate in the presence of the amount of moisture which is insufficient to cause complete germination.
  • Any animal or vegetable-based gelatin can be used in connection with the present invention, including the food-grade (sterilized) gelatin having a ph in the range of 3.5 to 8.0 and non-food grade gelatin.
  • an animal, food grade gelatin having a pH in the range from about 5 to about 6.5 is an animal, food grade gelatin having a pH in the range from about 5 to about 6.5.
  • the hardness of solidified gelatin can be described by its Bloom value.
  • gelatin having Bloom values in the range from about 50 to about 300 can be used in connection with the present invention.
  • the preferred Bloom values vary depending on the specific seeds that are coated and the specific composition of the formulation.
  • the preferred Bloom values are in the range from about 150 to about 250.
  • for potatoes Bloom values in the range from about 180 to about 200 are preferred. It has been discovered that the coating composition made from gelatin having the Bloom values in this range flows onto and adheres to the potatoes and it remains flowable even at relatively low ambient indoor temperatures.
  • the preferred gelatin has Bloom values in the range from about 150 to about 250.
  • the preferred Bloom values are from about 180 to about 220.
  • the Bloom value of the gelatin is preferably about 180.
  • the amount of gelatin in the coating composition is generally from about 2 to about 25 grams per liter of the coating solution but from about 80 grams to about 125 grams per liter on tubers and bulbs seeds.
  • the amount of the gelatin is in the range from about 2 grams to about 20 grams per liter of the coating solution but from about 80 to about 100 grams per liter on tubers and bulbs seeds. Any desiccant that can solidify gelatin to form a solid coating on the seed without cross linking the gelatin, can be used in connection with the present invention.
  • the presently preferred desiccant is gypsum.
  • the reason gypsum is preferred is that it absorbs water from the gelatin solution quickly to produce a gel.
  • the amount of desiccant in the coating composition should be sufficiently large to produce a gel that adheres to the seeds that are being coated. However, the amount of the desiccant should be sufficiently low to keep the gel flowable during the time period required for the application of the coating.
  • the concentration of the desiccant is in the range between about 0.25 grams to 1.5 grams per gram of gelatin, preferred is 0.5 grams to 1 gram of desiccant per gram of gelatin.
  • the coating composition of the present invention can preferably include a number of optional ingredients. Tallow can be added to increase the release rate of any active ingredient in the composition. Bulking agents, such as, clay, and preferably bentonite, can be added to give more body to the liquid coating composition. Coating compositions which include bulking agents produce more rounded coated seeds. Such coated seeds are generally easier to plant when using mechanical planters. The concentration of the bulking agent can be up to about 50 percent of the solids by volume.
  • an important aspect of the coating of the present invention is that it can be a carrier for active ingredients, such as, nutrients, trace elements, herbicides, pesticides nematicides, safeners, and fungicides.
  • active ingredients such as, nutrients, trace elements, herbicides, pesticides nematicides, safeners, and fungicides.
  • insecticides are particularly useful as active ingredients in coating compositions of the present invention applied to the following seeds and propagules:
  • fungicides are particularly useful as active ingredients in coating compositions of the present invention applied to the following seeds:
  • Additional active ingredients include: Gaucho and Tachigaren manufactured by Bayer and Thiram manufactured by Ciba. Where it is important that an active ingredient does not come in contact with the seed, multiple coatings can be applied to the seeds. The inner coating in contact with the outer surface of the seed then acts as a barrier between the incompatible seed and the incompatible active ingredient which is included in an outer coating. Multiple coatings can also be employed to include a certain type of active ingredients in one coating and a different active ingredient in another coating. This approach is particularly advantageous where the active ingredients in different coating layers are incompatible with each other or one another.
  • gelatin is added to water and the mixture is agitated until the gelatin is dissolved.
  • the agitation is provided by pumping the gelatin-water mixture.
  • Gelatin is preferably dissolved at atmospheric pressure.
  • the temperature is generally in the range from about room temperature to slightly below the boiling point of water. Preferably, the temperature is in the range from about 75 °C to about 99°C.
  • a desiccant, preferably gypsum, and active ingredients can be added to the liquid solution before, after or concurrently with the addition of gelatin. However, preferably gypsum and/or any active ingredients are added after gelatin is dissolved in water to form a solution.
  • the liquid composition of the present invention can be applied onto the seeds or plant propagules using any suitable apparatus.
  • the liquid composition is preferably applied using one of the systems constructed in accordance with the present invention: an electrostatic system, a rotating auger steeping system or a conveyor steeping system.
  • the electrostatic system is especially preferred.
  • the electrostatic system of the present invention imparts a negative charge to the seed and a positive charge to the liquid coating composition. As the positively-charged liquid comes in contact with the negatively-charged surface of the seed, the liquid is attracted to and quickly coats the entire seed.
  • seeds are fed into one or more tanks containing the liquid coating composition of the present invention.
  • the seeds or propagules are transported from the tanks into a drying zone drum using an auger.
  • seeds are placed on a conveyor belt.
  • the seeds are dipped at least once and preferably at least twice in the liquid coating composition of the present invention.
  • the conveyor belt then carries the seeds into a drying zone where forced air dries and solidifies the coating applied to the seeds.
  • Drying of the liquid composition of the present invention is generally carried out at a temperature in the range from ambient room temperature to about 70°F, preferably in the range from about 35°F to about 40°F.
  • the dried coated seeds or propagules can be sowed using standard sowing machinery or by hand. In the alternative, the coated seeds can be stored for later application. If the temperature and humidity are relatively high or if prolonged storage is contemplated, it is desirable to place on the surface of the coating an inert material, preferably a powder material, such as, chalk or talcum powder. Such inert material reduces the tendency for the seed to stick together or agglomerate.
  • an important advantage of the present invention is that the coating generally covers more than about 90 percent of the surface area of the seeds or propagules, most often over 98 percent. Another advantage of the present invention is that moisture required to break down the coating is also sufficient to effect complete germination of the seed or propagule. A further advantage of the present invention is that the germination of the coated seed or propagule is quicker than that of pelletized seeds. It has additionally been found that the liquid composition of the present invention can be applied as a coating over previously pelletized seeds such as pelletized sugar beets. Such applications can be made by apparatus such as described in Fig. 3-6. Among the benefits of such coatings over pelletized seeds is improved germination especially when active ingredients are included in the gelatin coating and not added to the pellet.
