SEED PROTECTION PRODUCTS AND METHODS
ORGANICALLY
The present invention relates to a product intended to allow the protection of seeds of all types of plants, trees and shrubs and in general any terrestrial plant, according to strict criteria of organic production, that is to say without additive linked to the mineral chemistry, and only produced by biological engineering processes.

The invention relates more particularly to a product based on materials of biological characteristics of plant origin without chemical additives allowing the protection of seeds against infestations of all types, in particular attacks by insect pests.

The present invention is based on the discovery of the possibility of assembling components of plant origin, in order to constitute a coating for protecting seeds which is stable and does not harm the germination capacity thereof.

The invention proposes to do this, a coating process using a viscous paste composed of extraction products from plants selected in natural production without fertilizers or fertilizers of chemical or mineral origin, therefore falling under the organic classification. This paste is produced according to a defined process, applied according to an adapted method, and the whole stored under conditions corresponding to the necessities of stability.

The seeds can then be used normally in the ground or on a nutricier or inert substrate, after dilution in water of the protective shell, either by soaking or by irrigation.

The field of application of this process and this product is that of the protection of seeds of all types of terrestrial plants, whether they are herbaceous plants, legumes, trees and other continental plant families.

The present invention relates to a biological product intended to protect the seeds of all types of continental plants, in any type of field whatsoever.

The present invention uses any type of plant having a repellency against insects or having an insecticidal power, any type of plant having juices allow sticking, any type of weak acid of biological origin, any type of anti-caking agent and first of all untreated natural talc, clean water (in the industrial sense of the term), a food-type dye.

The process for manufacturing the product according to the present invention is characterized by the extraction of Rotenone by mechanical and non-chemical means from selected plants, by methods of drying, grinding, steaming, crushing or any other process making it possible to collect either in the dry phase in the form of a powder, or in the viscous phase in the form of a paste, the solid and liquid materials present in the selected plant, after extraction of the esthers, either by drying or by steaming.

 It is also characterized by the extraction of Tephrosine (Oxydigueline) from the selected plant, Thephrosia (Vogelii), by grinding grinding / rolling under a cooled cylinder, with a final spacing of 1/100 of a millimeter under high cold pressure and short-term storage away from air and light.

 It is also characterized by the extraction of Pyrethrum using stems and leaves of Pyrethrum and Chrysantherum cinerarufolium, very finely cold grinding to obtain a paste. This paste is centrifuged to obtain a liquid constituted by the grinding juices. These juices are kept cold and protected from light.

Example of a process for the manufacture and use of the seed protection product
Basic selected plants:
Chrysantherum cinerarufolium
Pyrethrum
Derris Elliptica
Lonchorcarpus (Nicou)
Thephrosia (Vogelii)
Allium sphaerocephalum of strictly biological origin.

Rotenone extraction (H, 06)
Take the following plants and prepare them as follows:
Derris Elliptica, having been cultivated for two years. Defoliate and cut with the collar, to recover the roots.

Dry the roots at low temperature: 30 "C maximum in a flow of hot air, in a black enclosure. When the root has dried, that is to say when the proportion of residual water is less than 5% of the volume, grind and powder these roots.

This powder contains 5% rotenone.

Lonchocarpus (Nicou), creeper cultivated in an equatorial atmosphere. Take the roots of the liana, cut it into pieces of 3 to 4 cubic centimeters, steam them at 105 "C for 10 minutes to evacuate the esters. As soon as the baking is done, grind into dough under cover light. This dough contains between 30 and 35% rotenone.

Very short-term storage (a few hours) protected from air and light
Tephrosine (Oxydigueline) extraction
Take fresh stems and leaves of Thephrosia (Vogelii). Grind them to reduce them to an amorphous paste. This paste contains between 5% and 7% of Thephrosine (Oxydigueline). Keep it away from light and air.

Pyrethrum extraction
Take stems and leaves of Pyrethrum and Chrysantherum cinerarufolium. Grind them very finely when cold to obtain a paste. This paste is centrifuged to obtain a liquid constituted by the grinding juices. These juices are kept cold and protected from light.

Antibiotic binding preparation
Take fresh, organically produced Allium sphaerocephalum bulbs.

Very finely grind the bulbs to obtain a thick paste. The preparation should be done a few minutes before application in the coating paste.

Preparation of the coating paste
Take Rotenone extracts, Tephrosine extracts,
Pyrethrum, and the thick paste of the antibiotic bond. The whole will be kneaded cold to obtain a thick paste. Clean water will then be added in the industrial sense of the term, added to 10% of its volume by alcohol vinegar, to obtain a slightly viscous consistency at a pH always below 7, and a food coloring for the traceability (carotene). This paste will not be too fluid or will form lumps. Its viscosity should be of the order of 50 to 70 centistokes.

Seed preparation
The seeds will be harvested from plants produced by natural methods, free of fertilizers or chemical treatment products.

The seeds will be dried in a seed dryer by circulation of a breath of hot and dry air at 35 "C, for 6 hours, at the rate of a speed of passage of 5 cm second in the mass of the seeds.

When the seeds are dry, they are washed with a mild biological acid, such as wine vinegar or alcohol vinegar with a pH between 5 and 6. This rapid washing should make it possible to clean the shell of the seed, and rid it of alkaline deposits that may have formed on the seed coat.

The seeds are again dried in a seed dryer by circulation of a breath of hot and dry air at 35 "C, for 6 hours, at the rate of a speed of passage of 5 cm second in the mass of seeds.

When the seeds are dry, they are poured into a cold mixer
Coating
When the seeds are placed in the cold mixer (concrete mixer), the coating paste is poured at a rate of 1/4 of the volume occupied by the seeds, and the assembly is left to rotate in the mixer until obtaining full seed coverage. If lumps are formed, the viscosity of the coating paste is too high. Clean water is then added in the industrial sense of the term to fluidify the whole and obtain a homogeneous coating.

When the seeds are well coated, fine industrial talc is poured in due to the volume occupied and the treated seeds are well separated.

When the seeds are well separated, they are passed through a seed dryer exposed to a breath of dry air at 35 "C, for 3 hours, at a rate of passage of 5 cm second in the mass of seeds.

The seeds are then ready.

Storage
The seeds are then stored protected from light, under vacuum, in packages made of shrinkable silver polyester films. The sachets and bags thus produced are stored in a dry place, protected from light, and at a temperature between 1 "and 20" C.

Application domain
The product and the application process can be used in any type of plant culture, on all types of seeds, then used alone, either in symbiotic association or in antinomic association (systemic treatment against weeds, by a natural hormonal system) .
