It has now been found that an increase in crop yield and an improvement in its technological quality can be achieved by the application of a composition comprising as active ingredient one or more 1,2,4-triazin-5 (4H) -one derivatives of the general formula 1

The ^{r R} r ies;

Wherein R is methyl, C 1 -C 2 alkoxy, C 1 -C 4 alkylamino, anilino, dimethylamino, piperidino, morpholino · 2, R is C 1 -C 4 alkyl or R can be the same or different radical and can be hydrogen, acetyl or methyl, R 2 can be taken together to form C 2 -C 4 alkylidene or C 6 cycloaliphatic, optionally substituted 2-furfuryl alkylidene , halogenphenyl or nitrophenyl, R 'represents an alkyl group linear or branched having 2 to 4 carbon atoms, phenyl, optionally substituted by halogen, benzyl or cyclohexyl. . *

Crop crop control with the composition of the invention is achieved by application at various stages of crop development, either before or after pre-emergence or post-emergence over a period of 3 weeks to 7 months prior to harvest. The crop enhancement product can be taken up by the useful plants either through the soil, i. j. through roots or by spraying, through a leaf. The effects of compounds on plants result in changes in the physiological processes of plants, which manifest themselves in the regulation of assimilation production and there is an increased deposition of assimilates in economically important organs.

This results in not only an increase in crop but also an improvement in the technological quality of the crops, which leads to a considerable economic benefit in their cultivation. It has further been found that the composition according to the invention containing 1,2,4-triazine-5 (4H) derivatives as active ingredient of the above formula I is an effective crop regulator for a wide variety of cultivated plants. The effect is particularly apparent in cereals, such as e.g. wheat / Triticum /, rye / Secale /, barley / Hordeum /, rice / Oryza /, oats / Avena /, but also in other agricultural plants. such as sugar beet (Beta vulgaris), sugar cane (Saccharum officianura), cotton (Gossypium), corn (Zea mays), rape (Brassíca napus var. Arvensis./, soybean (Glycine), bean (Phaseolus), potato (Solanum tuberosum), pea (Pisum sativum), carrot (Daucus carota) and others.

Application of the composition according to the invention can be carried out by spraying, watering, spraying, fogging, sprinkling, spreading on whole plants or on the surface of the soil or by incorporation into the soil to the desired depth, either by surface or strip treatment between rows or rows.

Suitable dosage forms are solutions, emulsions, dispersions, aqueous or oily suspensions, wettable powders, dusts, dusts, dusts, pastes, granulates or microgranules, with the addition of liquid and / or solid carriers, or diluents, wetting agents, adhesives, binders, modifiers, surfactants. substances, emulsifying agents and / or dispersing agents, antifoams, dyes.

w '

Suitable liquid carriers are, for example, water, aliphatic hydrocarbons such as cyclohexane, paraffins, aromatic hydrocarbons such as benzene, toluene, xylene, chlorinated hydrocarbons such as carbon tetrachloride, ethylene chloride, chlorinated aromatics, alcohols such as methanol, butanol and their ethers, glycols, ketones such as acetone. Methyl isobutyl ketone, cyclohexanone, isophorone, strongly polar solvents such as dimethylformamide and dimethylsulfoxide, aqueous application forms are preferably emulsions and dispersions. The subject substances are homogenized in water either as an individual or dissolved in one of the abovementioned solvents, preferably with emulsifiers or dispersants. The cationic emulsifiers may be, for example, quaternary ammonium compounds, the anionic emulsifiers, for example, soap, greasy soap, alkali salts of long-chain aliphatic monosulfones, aliphatic-aromatic sulfonic acids or long-chain alkoxyacetic acids and non-ionic polyethylene glycol ethers ethylene oxide.

It is also possible to prepare liquid or paste concentrates consisting of the active substance, an emulsifier or a dispersant and, if appropriate, solvents, which can then be diluted with water. Wettable powders can be made 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, norm. calcium phosphate, sand, silica gel. In many cases, it is preferred to use mixtures of different carrier materials. However, it is also possible to apply the active ingredient to the carrier by means of a carrier. volatile solvents. By the addition of wetting agents, the powdered formulations and pastes can be converted into a water-suspendable state, thus allowing their use as a spray.

Examples of suitable dispersants are the condensation products of sulfonated naphthalene and sulfonated naphthalene derivatives with formaldehyde, the condensation products of naphthalene, optionally of naphthalenesulfonic acid with phenol and formaldehyde, as well as the alkali metal, ammonium, alkali metal, ammonium and alkali earth metal salts of lignosulfonic acid. , dibutylnaphthalenesulfonic acid salts, sulfated fatty alcohols as well as sulfated hexadecanols and sulfated fatty alcohol glycol ethers, di-tertiary ethylene glycols, dialkyldilaurylammonium chloride, alkali metal and alkaline earth metal fatty acid salts, methyl sulfite leach or sulfite waste.

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

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

Suitable solid carriers are natural stone materials such as kaolins, alumina, talc, quartz, attapulgite, raontmorillonite, pumice stone, limestone, marble, sepiolite, dolomite, bentonite, vermiculite, diatomite, bitumen, mica, ground organic products such as sawdust, coconut shells, tree bark, corn cobs, activated charcoal and more.

Adhesives such as cellulose carboxymethylenes, natural and synthetic powdered, granular or latex polymers such as acacia, lava 1 and polyvinyl acetate may be used in the treatment.

Polymeric microgranules can be produced by impregnating the active ingredients in the form of solutions with the active substances, for example, to form a porous polymer-based granule (polyester, polymethacrylate, polyacrylonitrile, urea-formaldehyde and others) with a suitable surface and suitable absorption and desorption properties.

A

In addition, these agents may contain colorants such as inorganic pigments, for example iron oxide, titanium dioxide and ferrocyanide blue, or organic colorants such as alizarin and metallic azophthalocyanine dyes as well as trace elements.

The proportions of the active compounds in the various preparations can be varied within wide limits and can range from 0.01% to 95% by weight. The amount of active substance used to treat the crop for crop control is 0.5 g / ha to 100 g / ha and depends on the type of substance used, the form of its finishing, the method of application, the time of application, the type of crop, environmental conditions and other factors.

The active compounds in the composition according to the invention can be used either alone or in mixtures with one another. In various cases, it may prove advantageous to combine with other plant growth regulating agents, including, but not limited to, ethylene-releasing substances of different chemical structure, onium compounds, maleic hydrazide, abscisic acid derivatives, auxin-like chlorinated phenoxyacetic acid derivatives.

The following examples illustrate but do not limit the use of the compositions of the present invention to increase crop yield and technological quality.
