Although the results reported in the cited literature are positive, they have not led to the development of the sugar beet regulator and its application in practice. On the other hand, Frank R. describes, in a work published in Weeds 14, 82 (1966), a severe damage to sugar

200,988 years of petroleum epoeobically treated with atrazine and eimaxin residues, even β, even several years after the application of these triazine herbicides in the form of grandiose.

It has now become apparent that an increase in the yield of root and sugar beet of chicory may be achieved by the application of one or more triazines of the general formula I

in which the substituent R ^{1 is a} modified Cl, alkoxy-C 1 -C 2 alkyl or C 1 -C 2 alkylthio group, azidoacyl, C 1 -C 2 alkylamino, and alkoxyalkoxy group having a total of 2 to 3 C atoms, the C 1 -C 3 alkylamino group C atoms and in which the substituents R ² and R 2? can be the same or different and are amino, alkylamino and 1 to 5 C atoms, alkenylamino or 2 to 3 C atoms, and linear or branched relation, dialkylamino and 2 to 4 C atoms, cycloalkylamino and 3 to 6 C atoms, morpholino amino e having 1 to 4 C atoms, an alkoxyalkylamino group having a total of 2 to 7 carbon atoms, a methoxyamino group, an N-alkoxyalkylamino group having a total of 2 C atoms, a hydroxyelkylamino group having 1 to 2 C atoms, a N-acylalkylamino amino group, , methylthio or C 1 -C 2 alkoxyacupine modified in the form of a wettable powder, solution, emulsion, suspension, paste, dust, granulate or microgranulate according to the invention.

The principle of the invention consists in applying e-triazines of the formula I before application of seed, or pre-emergence or post-emergence in the range of 1 to 7 months before beet color, in an amount of 3.0 g to 200 g of active substance per hectare or to the podium.

S-triazines of the general formula Za and can be applied by conventional apoa, for example by spraying, watering, spraying, poeyp, spreading to the surface of the podium, or into the podium to the desired depth, either by surface treatment or pale, interline or line.

The process according to the invention ea achieves an increased yield in various stages.

As a result of the β-triazine treatment of sugar beet rapids after abaorption through the root system and trancallocated into the castings at the sites of action and changes in the physiological processes of raspberries, which are implicated in the regulation of aeration production, in addition to increased formation of eacharosis and its deposition. This will increase sugar beet yields per unit of utilized area, improve the technological properties of sugar beet, and thus make a considerable economic contribution to its cultivation and sugar production.

When selecting a suitable dosage of the active ingredient for regulating sugar yield and sugar beet sugar, it is necessary to consider that the exact dosage depends on the mode of administration, the dosage form selected, the stage of development of the sugar beet, the conditions and other factors well known to those skilled in the art.

To prepare and possibly use solid or liquid carriers e additives, for example naturally or regenerated natural substances, solvents, disintegrants, wetting agents, thickening agents,

Adhesives, binders and dyes.

In particular, organic liquids, mineral oil fractions, coal tar oils, and vegetable and animal oils may be used to prepare the solutions. In order to facilitate the dissolution of the active substances in these solutions, it is possible to add, if necessary, a small amount of organic liquids β with better solubility, which in most cases also have a lower boiling point, i.e. a lower boiling point. solvents such as alcohols such as ethanol or isopropanol, ketones such as acetone, butanone, or cyclohexanone, diacetone alcohol, cyclic hydrocarbons such as benzene, toluene, xylene, chlorinated hydrocarbons such as tetrachloroethane, ethylene chloride or mixtures of the above.

Suitable aqueous application forms are, in particular, emulsions and dispersions. Said substances are homogenized in water either as individual substances or dissolved in one of the abovementioned solvents, preferably by means of emulsifiers or dispersants. Of the cationic emulsifiers, for example, quaternary ammonium compounds can be used, of the anionic emulsifiers, for example, soap, gooey soap, long chain alkali aliphatic monosulfones, long chain aliphatic-aromatic acids or long chain alkoxyacetic acid polyol ethers and nonionic polyethylene glycol ethers ethylene oxide products. Liquid or pasty concentrates may also be prepared, consisting of the active ingredient, an emulsifier, or a dispersant and optionally a solvent, which may then be diluted with β water.

Wettable powders can be prepared by mixing the active ingredients with dispersants and powdered carriers to form a homogeneous mixture and grinding them. Suitable carriers are, for example, talc, diatomaceous earth, kaolin, bentonite, calcium carbonate, normal calcium phosphate, sand, wood flour and / or other plant origin material. In many cases, it is preferable to use mixtures of different carriers. However, the active ingredient is applied to the carrier by means of a flowing solvent. By the addition of wetting agents, the powder formulations can be brought into a water-dispersible state, allowing their use as a spray. Examples of suitable dispersants are the condensation products of sulfonated naphthalene with formaldehyde, the condensation products of naphthalene, optionally of naphthalenesulfonic acid with phenol and formaldehyde, as well as the alkali metal, ammonium and alkaline earth metal salts of lignosulfonic acid, alkylarylsulfonates, salts of sulfated hexadecanols and salts of sulfated glycol ethers of fatty alcohols, di-tertiary ethylene glycols, dialkyldilaurylammonium chloride, alkali metal and alkaline earth metal salts of fatty acids, lignin, sulphite waste liquors and methylcellulose.

Suitable anti-foaming agents are, for example, silicone oils.

Granules to be applied to the soil can be prepared by agglomeration or impregnation. The granules may contain from 0.01% by weight to 25% by weight of the active ingredient and from 0 to 10% by weight of other additives as stabilizers, modifiers allowing slow release of the active ingredient, binders and solvents.

Suitable solid carriers are natural stone materials such as kaolins, alu4

200 9SS mines, mawtenec, quartz, attepulgite, montmorillonite, pumice stone, limestone, marble, eepiolite, dolomite, bentonite, vermiculite, diatomite, feldspar, mica, ground organic products such as sawdust, coconut shells, corn cobs, charcoal and charcoal.

Adhesives such as carboxymethylcellulose, natural and synthetic powdered, granular or latex polymers such as gum arabic, polyvinyl alcohol, and polyvinylation melt may be used in the treatment.

Polymeric microgranules aa can be prepared by impregnating the active ingredients in the form of light solutions and solvents, for example, with a suitable surface and suitable swelling properties of the absorbent and desorption by impregnating the active substances in the form of light solutions and solvents with a suitable surface and suitable flow properties of the porous polymer / polyester, polymethacrylate, polyacrylonitrile, etc.

Furthermore, these compositions may contain dyes such as inorganic pigments, for example iron oxide, titanium dioxide and ferrocyanide blue, or organic dyes such as alisarine and metallic azophthalocyanine dyes as well as trace elements.

The S-triazine compounds may be used either alone or in admixture with each other.
