Definitions
- the present invention relates to the technical field of coating seeds or seeds, in particular for agriculture and for the commercial or private sector of horticulture.
- the present invention relates to a seed coating composition, in particular for finishing seed, with at least one antistatic or electrically conductive or electrodissipative coating.
- the present invention relates to the use of an at least substantially metal-free, preferably metal-free, and electrically conductive additive for producing a seed coating composition or seed coating and the use of an at least substantially metal-free, preferably metal-free, and electrically conductive additive for the antistatic or electrically conductive or electrodissipative equipment of seed or for the corresponding equipment of a seed coating as such, which is applied to the seed.
- the present invention relates to the use of the seed coating composition according to the invention for the antistatic or electrodissipative equipment of seeds.
- the present invention relates to a method for producing the seed coating composition according to the invention, which has antistatic or electrically conductive or electrodissipative properties, and the seed coating composition obtainable by the method according to the invention as such.
- the present invention relates to a method for producing a seed coated with a coating, in particular in the form of seed grains or the like.
- the present invention also relates to the seed according to the invention, in particular in the form of seed grains or the like, which is equipped with an antistatic or electrically conductive or electrodissipative coating based on the seed coating composition according to the invention.
- Seeds which are generally in the form of particulate seeds or (plant) seeds, are in particular generative or germinable reproductive organs of plants, which generally contain the complete fertilization-originating germination plant of the plant and are usually in a dormancy.
- the dormancy can be interrupted by special factors such as moisture, temperature, light or the like, resulting in the subsequent germination of the seed with formation of the sprout or the (young) plant.
- seed which is used for example in agriculture in large quantities for the order of fields, but also in smaller quantities in the field of horticulture, is a sensitive biological material which, in particular in the case of non-optimal processing and storage of quality or quality Germinability may be lost, for example if the seed is processed or stored under too warm, too humid or under too light conditions.
- the seeds can spoil in unfavorable processing and especially in unfavorable storage conditions within a short time or become useless under loss of germination, the corresponding failures are caused for example by premature and thus unwanted germination or due to infestation with fungi, parasites or the like can.
- the resulting loss of quality leads to a non-optimal use or germination of the seed, along with yield losses, and thus to a financial loss, especially as it is industrially offered seed to a high-performance and cost-intensive specialty product.
- High losses of germinable seeds are also important in view of less expensive seed varieties, as such varieties are often in very stored much larger quantities, which increases their vulnerability to unfavorable environmental factors in addition.
- seed coating the equipment of seed with a coating or coating is known, which is generally referred to as seed coating.
- the coating or shell compositions used for this purpose are equipped with different materials that are to improve the seed quality, such as bactericides or fungicides, which in particular improve the storage stability of seeds, due to a reduced bacterial or (mold) fungal infection should.
- coating systems known in the art may be provided, for example, with germinating or growth promoting substances such as fertilizers and vitamins, on the one hand to optimize nutrient supply growth conditions, and herbicides on the other hand so as to prevent the growth of competing weeds or the like, especially during the germination phase of the seed.
- germinating or growth promoting substances such as fertilizers and vitamins
- seed coating systems are also used against the background to increase or standardize the mass of the seed, in order to improve in particular filling, dosing and Austragungsreae or seeding of the seed.
- dyes or color pigments are often used, in particular in order thereby to allow visual identification of the seed.
- WO 2012/1 18795 A2 or US 2012/220454 A1 relates to a seed composition based on polymers, on the basis of which the water absorption of the coating is to be increased. Furthermore, WO 2007/033931 A1 or US 2009/270259 A1 relates to a process for producing a formulation with controlled release of active ingredient, which can be used as a seed coating, wherein the composition may equally contain growth-promoting or biocidal active ingredients.
- EP 2 229 808 A1 or US 2012/065060 A1 relates to a coating system for plant seeds which, in addition to inorganic particles, contains further ingredients, such as growth-promoting substances and biocidal substances.
- further ingredients such as growth-promoting substances and biocidal substances.
- dye or effect pigments is described.
- a disadvantage of known coating systems in general is often their non-optimal composition, in particular with regard to environmental or food-specific aspects, which also applies in particular against the background that in the prior art sometimes metal or heavy metal-containing compounds are used, for example in shape of color pigments or the like.
- the seeds forming the seed can in particular in the context of industrial processing, for example in coating operations or in the packaging or portioning, and in the context of handling the end user, for example, when removing from an outer packaging or when sowing, electrostatically charging, which can lead to sometimes serious problems, especially during processing or portioning, when removing from a package or when spreading or sowing the seeds.
- electrostatic charge is to be seen in particular in the dielectric properties of the seed as well as in the movement and friction of the seed during processing or handling, which leads to a corresponding charge separation with accompanying electrostatic charging of the seed.
- the flowability of the seed is significantly deteriorated by the electrostatic charge, which is problematic in terms of portioning or separation of the seed, which weighs all the worse, especially in highly industrialized agriculture, an efficient use of the seed not least for economic reasons of great Meaning is.
- the effects associated with the electrostatic charging of the seed are disadvantageous, for example as regards the handling of the seed when it is removed from (re) packaging or the like, because the individual seeds often adhere to the packaging, which is undesirable.
- Another approach in the prior art is to equip the coating system by the use of inorganic compounds containing heavy metals with antistatic properties.
- the use of antimony-doped tin oxides is provided in particular in the prior art.
- the disadvantage here on the one hand the poor handling, since the subject inorganic compound is applied as a separate layer, and on the other hand resulting from the use of heavy metal compounds resulting poor environmental compatibility and lack of food compatibility.
- Another approach in the art is to see the use of specific salt compounds based on tetraalkylammonium salts. These have due to their polar structure sometimes strong hygroscopic properties, so that due to the associated water retention in the layer, a certain conductivity results. In this regard, however, is particularly disadvantageous that too high water contents in the underlying layer, for example, induce premature germination of the seed or can lead to a mold or fungal attack.
