Description

FIELD OF THE INVENTION The present invention relates to a dressing additive comprising an oil for adhering the active ingredient (s) producing the desired effect (s) to the plant parts (seeds, tubers) and forming a protective coating.

The safety of plant production is endangered by many diseases and pests, including fungal diseases, insects, mammals. Serious damage may result from chewing the seed or seedling, diseases of the seed and the plant that develops from it. Germinating seeds, tubers and a few leafy plants are the most defenseless and any damage to it can be fatal. However, there are some diseases which, although they are caused by infection with the seed, still occur at birth. such as the most well-known corneal diseases.

In order to prevent serious damage, seed treatment, a process known as dressing, has long been used to ensure the food supply of the population. The essence of the process is to contact the plant's reproductive organs with chemicals, commonly known as plant protection products, that kill harmful organisms in or near the seed, thereby providing healthy seed and preventing the spreading of soil from different sources, sucking-chewing pests harmful to soil. Substances which, when absorbed into the plant, provide protection for the plant itself for a longer or shorter period are also known.

The essence of the dressing process is that the propagation material and the agent intended to protect it are in permanent contact and that this relationship is maintained upon arrival.

Nowadays, seed dressing additives, which promote the adherence of seed dressings and the fungicides used, are increasingly used in seed dressing technology.

First of all, users need a highly adherent, intensive coloring, fast-drying, non-active additive, which is the only way to solve the problem of material-saving dressing according to the degree of contamination of the seed lots (smart plant protection).

Known dressing technologies:

1.) Wet dressing: the product is suspended in water or dissolved if it is soluble. In this mixture, the seeds are bathed, then filtered and dried. In this way, a good connection is established between the agent and the core, but in many cases the amount of agent required to secure a unit of core does not adhere. Further disadvantages are the complexity of the process, the high labor requirements and the cost of drying. Therefore, this procedure is no longer applied.

2.) Dust treatment: The disadvantages of wet dressing are to be eliminated. The process involves finely grinding the active ingredient of the plant protection product and adding a powder additive that adheres to it. This method also has serious disadvantages. The powder adheres only to the outer surface of the propagation material and usually avoids germination. In the absence of moisture, absorbable materials can penetrate the seed only after sowing under the influence of soil moisture. The adhesion on the dry core is poor and thus it is difficult to apply the required amount of grain. Finally, most of the product is dusted during the handling and transport of the seed and thus has no effect, and is a source of health damage to the operator.

3.) Humidified dressing: A pesticide slurry is made up with as much water as the seed can absorb without raising its moisture content beyond storage. As you can see, this procedure is designed to minimize the disadvantages of wet and dust treatment, while minimizing the disadvantages. However, this is only possible with some compromise. It is a serious problem that after drying, a significant part of the pesticide is dusted here. Water-soluble adhesives are used to aid in swelling. These substances dissolve in water to form colloids and increase the viscosity of the solution, even at high dilution, to give a dense unmanageable slurry, but if less adhesive is used, the biological effect is lost as much of the pesticide is dusted during storage .

Known dressing agents. additives

1.) Combined agents (Evershield, Buvishield product families) containing the active ingredients of the dressing agent in a predetermined proportion in a plastic dispersion are marketed. In this way, the active ingredient is patched onto the core with the film-forming plastic. The disadvantage of this process is that the composition of the active compounds is not adapted to what is required to combat the type and extent of the infection. This requires, on the one hand, the marketing of at least mixtures adapted to the major cultures and, on the other hand, results in wasteful use, for example, in the case of a weak infection other than being more potent and therefore more expensive. Other disadvantages include reduced germination power and seed sticking.

2.) To overcome the above difficulties, dressing aids containing no active ingredient have been developed. Essentially, they are solvents, such as alcohol, of a natural resin, pine, shellac, or synthetic resin. These should be mixed with the seed dressing slurry and applied to the core. During dressing, the seeds treated in this way are

-2193637 Solvent and excess water should be removed by drying. Drying should be carried out while the seeds are constantly being moved to prevent them from sticking together. Therefore, special machines designed for this purpose are needed to accomplish this.

Such a seed coating process is described in

European Patent No. 010 630 (binder shellac).

European Patent Publication No. 0 013 763 (vermiculite, orillanalate is used as coating material);

Japanese Patent Publication No. 2631032 (Maltotriase Polymer).

The present invention is based on the discovery that by using a pre-formulated emulsion of vegetable, animal or mineral oils as a dressing aid, even in the case of dressings made from plant protection products of varying quality and quantity, a good adhesion and uniform film-like coating is obtained.

The treated seed or coating after treatment does not change during storage, packaging, transport and sowing, and there is no loss of dust. Seeds germinate well and protection is expected based on the amount of active ingredient used and the amount of infection. The seed treated with the product according to the invention does not require any special treatment (e.g. drying), since the applied material does not apply the pesticide to the seed, but does not apply to the seed. The dressing does not require more moisture than the wetted process described. After the operation, the dressed product can be packaged and stored immediately. With it, you can apply the most favorable version of the service and thus the most economical procedure. Due to the nature of the excipient, it is well compatible with both fungicides and insecticides, as well as wild repellents and other auxiliaries.

The present invention is based on the discovery that adhesives for dressing agents can be solved not only with the adhesives and excipients used hitherto, but also, by their very nature, in the case of cores with a lipophilic surface, oils which cover all parts of the plant. When the oil is dispersed in water in the form of fine droplets, it is possible, if necessary to dissolve the dyes in the aqueous phase, to render the pesticide applied on the seed lossless.

The additive of the present invention may be prepared by any of the known emulsification methods _according to the following composition: Oil / s 10-80% by weight of emulsifier (s) 2-7% by weight of water 100% by weight of dye 0-12% by weight

Preferably, the composition of the present invention can be prepared by the following process:

The aqueous phase dye component is preferably dispersed in water or in an aqueous mixture under slow stirring at 35-40 ° C. Prepare by mixing the oily phase containing the oil-dissolved emulsifier.

For the aqueous phase, the oily phase, preferably with a high shear emulsifier mixer (circumferential speed of 5-25 m / s, hereinafter referred to as "vigorous mixing"), is continuously stirred at ca. 1-10 minutes. After the addition of the complete oily phase, the resulting emulsion is stirred for another 3-5 minutes.

Various water-soluble paints or dispersions may be used as colorants, preferably food colorants or rhodamine-type paints.

Non-ionic alkyl 40 aryl polyglycol ethers or known oil emulsifiers are generally used as emulsifiers.

As an oil, vegetable, animal or mineral oils such as paraffin oil, soybean oil, sunflower oil, rapeseed oil, fish oil, preferably pa ₄₅ raffin oil can be used.
