Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bean-boosting agent containing 3- (4-chloro-3-toluyl) -1,1-dimethylurea as the active ingredient.

It is known that 3- (4-chloro-3-toluyl) -l, l-times per day · tylmočovina (chlorotoluron), the active ingredient of herbicidal compositions using the ^Mark: early grain and the poppy at a rate of 800-1300 g as / ha.

Z čs. AO č. No. 209,626, chlorotoluron is known to be the active ingredient in a crop-enhancing crop and quality for cultric beet, earth ^; metals and soybeans.

It has now been found that the increase in bean yield can be achieved by applying the composition according to the invention, which comprises 3- (4-chloro-3-thiolyl) -1,1-dimethylurea as the active substance.

Fazuía is an agricultural crop whose cultivation is of great national economic importance, taking into account nutrition there, especially due to its high protein content,

Bean crop control by the composition of the invention is achieved by application at various stages of crop development, either before sowing, simultaneously by sowing, pre-emergence, or post-emergence at a time interval of up to 3 weeks before the arms.

Crop enhancers can be taken up by bean plants either through a pod (through the roots) or by spraying (via foliage). Resulting effects are changes in the physiological, biochemical and morphogenetic processes of the plants, which manifest themselves in regular assimilation products, thereby increasing assimilate deposition. This will not only increase crop yield but also improve technological quality, ie higher protein content in winter compared to plants to which regulators have not been applied.

The application of the composition according to the invention can be carried out by spraying, pouring, pouring, spraying, fogging, on the whole plant or on the soil surface, or by incorporation into the soil by surface or strip treatment.

Suitable dosage forms are solutions, emulsions, dispersions, suspensions, aqueous or oily, wettable powders, dusts, dusts, powders, pastes, granules or microgranules, with the addition of liquid and / or solid carriers, optionally diluents, wetting agents, adhesives, binders, modifiers, surfactants, emulsifiers and / or dispersants, anti-foaming agents, pigments or dyes.

Suitable liquid carriers are, for example, water, aliphatic hydrocarbons, paraffins, aromatic hydrocarbons, chlorinated hydrocarbons, ethylene chloride, chlorinated aromatics, alcohols and their ethers, glycols, ketones, dimethylformamide or dimethylsulfoxide.

Of the aqueous application forms, especially emulsions and dispersions are suitable. The subject substance is liomogenized in water either alone or dissolved in the nickel of the solvents mentioned, preferably by means of emulsifiers or dispersants.

The cationic emulsifiers may be, for example, the quaternary ammonium compounds, the anionic emulsifiers, for example, soap, sticky soap, alkali salts of long-chain aliphatic monosulions, or salts of aliphatic-aromatic siulfonic acids, or alkyl-phenoxy-ester alcohols, polycoradenzation products of ethylene oxide.

It is also possible to prepare liquid or pate-like concentrates consisting of the active substance, an emulsifier or dispersant, the torus and, if appropriate, solvents, which can then be diluted with 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 carrier materials are, for example, talc, diatomaceous earth, kaolin, bentonite, calcium carbonate, ball, silica gel. The preparation can be carried out by applying the active ingredient to the carrier by means of a volatile solvent.

By the addition of wetting agents, the powdered formulations and pastes can be rendered suspendable in water, whereby they can be used as a spray. As dispersants there may be used, for example, the condensation products of sulfonated naphthalene and sulfone derivatives of naphthalene with formaldehyde, the condensation products of naphthalene, optionally naphthalenesulfonic acid with phenol and formaldehyde, as well as alkali metal salts of ligninsulfonic acid, sulfated hexadecanols and salts of sulfated fatty alcohol glycol ethers, di-tertiary ethylene glycols, dialkyldilaurylammonium chloride, alkali metal and alkaline earth metal salts of fatty acids, lignin sulfite waste materials or acetylcelluloseZH.

Granules and microgranules intended for application to soil or foliar may be prepared by agglomeration, impregnation or coating. The granules may contain from 0.01%; up to 25% by weight of the active ingredient; and from 0 to 10% by weight of other ingredients such as statoilizers, binders, plasticizers, solvents, adhesives and modifiers.

Suitable solid carriers are natural stone materials such as alumina, talc, quartz, diatomite, feldspar, kaolins, montmorillonite, saponite, chalk, limestone, sepiolite, chlorite, bentonite, vermiculite, atapulglt, zeolites, ground organic products, sawdust, torture from the bark of stroη mov, corn cobs, actively ulily and more.

Adhesives such as carboxymethylcellulose or acetylcellulose, natural or synthetic powdered, granular or latex polymers such as acacia, polyvinyl alcohol and polyvinyl acetate may be used in the preparation.

The polymeric microgranules can be prepared by impregnating, for example, the porous polymer-based granulate with the active ingredients in the form of their solutions and removing the solvent.

The range of active substances in the various preparations can be varied within wide limits and can range from 0.01 to 95% by weight. The amount of active ingredient used to treat the crop depends on the form of its final treatment, the method of application, the time of application, ecological factors, the amount of nutrients used in the pod and the cultivated cultivar. It ranges from 0.001 to 0.02 kg / ha. Heirbicidal effect does not occur at these doses.

The following example illustrates but does not limit the invention.

Example 1

Bean plants (Phaseolus vulgarisj were grown on 1 m ² parcels. In the developmental stage prior to flowering sticks treated with sprayed doses of 3- [4-chloro-3-toluyl) -1,1-dimethylurea, which was foirmufed to a wettable powder and dissolved in water to a 0.01% solution. The bean yield was evaluated by determining the total weight of the ff.n after harvest from the treated parcels and comparing it to the untreated control.
