The present invention relates to a composition for preventing germination of edible and economic seeds in ventilated fan stores. Šie Obvious common anti-germination agents eu applied in the form of powder dust. The use of powdered binder in large warehouses is technically foot and is used in quail. These are vaporized or dusted, eg compressed air. The aforementioned nodes are malfunctioning, machine-intensive with low labor productivity. Significant positions are impressed by the dagger on neglect of the germination, which are made up of an active ingredient with psstlcidnya effect, and an incendiary propellant. The propellants contain nitrogen-releasing or carbon dioxide-releasing compounds, most preferably azodlcarbonanide and / or Ν, Ν-dl-trisopentamethylenetetranine / 3ap. pat. No. 57, 55,378; 60 42,302 and No. 81 77,202 etc./. For the purpose of improving the stability and reliability, the compositions comprise, for example, nitrocellin, nitrocellulose, CH-cellulose, diatomaceous earth, granular calcium metal, carbon powder, nanganate, strontium nitrate, talc, 11 and glass fibers. pat. No. 58,140,002; No. 58 32,801; No. 58,172,303; 81, 75, 402).

The aforementioned calculation of the modifiers extends the present invention, which relates to the funcant formed by the volatile insecticide and / or fungicidal, bactericidal, or second pesticide, inflammatory propellant and flame regulator. The flame retardants used are water-soluble urea-formaldehyde condensates, sulfonated compounds, lignin, zeolites, triarylphosphates, derivatives of alkylene oxides or siloxanes, trloxane, N, N-biscarbamoylhydrazine. to the weight of the funcant. An advantage of the present invention is the technical and economical availability of a modification modifying flame-retardant flame. The product has good physico-chelating stability due to segregation and thermal efficiency. The proper interaction of the propellant and the regulator provides for the release of the aerosol in the form of a hub, in which the active substance is uniformly dispersed, e.g. prof, chlorpropham, 1-naphthylacetic acid methyl ether, maleic hydrazide et 3. The active ingredient ee in the air stream introduces the ventilated storage of earths to the fans, where it is settled. This is a cell from the cells of the shoots, so that cell division and hence growth of the clusters is inhibited. Suppressing atranspircle in addition to maintaining nutrients and reducing weight loss by about 20%. The stored earths are full-fledged as a food to the brink of a new crop. In addition to preserving the quality of Edible Ears, there are some other advantages, for example, that the refining technique can be used without fail until the end of storage time, and at the time of bridging the processed potatoes, a significant reduction in peel in peeling operations.

Under the water-insoluble urea-formaldehyde condensate form, the polymeric ureas are characterized by an initial mole ratio of formaldehyde to urea of 0.7 to 2.5, and preferably 0.85 to 1.9.

The source of the lyophilized lignin compounds is in particular the production of pulps. These products have chemical reactions of lignin with cooking chemicals. The essence of these reactions is the cleavage of the lignin-celulfite complex and the lignin macromolecule, while increasing its solubility by the resulting hydrophilic groups. Lignosulfonate acids still react within the cell ethane with the cation of the boiling solutions to form lignosulphonates, which then easily diffuse into the boiling medium. Leaching material from acidic cooking processes is an aqueous solution of inorganic and organic compounds with a dry weight of 9 to 14% by weight. About 65% of the dry matter content is represented by lignin compounds, 25% of the carbohydrate content, including simple pentoses and hexoses, aldonic acid and alduronic hyaluronic acid, and the remaining 10% are inorganic compounds such as sulfur dioxide, sulphite and sodium sulphate, magnesium , calcium and ammonium. The content of saccharides can be altered by, for example, a biological treatment, after which the content of reducing saccharides is reduced to a value of 0.1 to 0.2% by weight. based on sulphite leachate. For the isolation of ligno-2 acids of 269554 B1 sulphonic oily sulphide voids, there are a number of red methods that can be utilized: membrane eerectomy, erythropoiesis, electrochemical, irystllotin, chemical precipitation, and the like. The sulphonated lignin compound as a regulator may be used in the form of a ligno-sulphonated acid. It should be noted that the sulfonium sulfonate contained in the sulphite liquor is highly polydisperse material. The average relative molecular weight ranges from several hundreds to less than hundreds of thousands. Generally, it is known that low molecular weight fractions of lignosulfonic acids are sulfonated and have a nearly linear structure. . Preference is given to the application of lignosulfonic acid in the form of its sodium salt, calcium, magnesium, and the like. separate elebo in a mixture. The products of the lignosulfonic acid precipitation, respectively. a salt thereof, a precondensate prepared by condensation of amide derivatives of carbonic acid or thiocarbonate with aldehyde.
