The object of the present invention is a fungicidal composition suitable for the treatment of fungal diseases of crops, which contains vegetable oil with a high potential for drying, and a method of treatment of cultures with the use of the composition according to the invention.

There is a need to reduce the number of chemical products distributed in the environment for the treatment of fungal diseases of crops, in particular by reducing the applied doses.

For this purpose, some special additives called biological activators, such as mineral oil, wetting agents and impregnating agents, combined with industrial tools, allowing, for example, to combine a special additive type of mineral oil with antifungal compounds, which can be an advantage consisting in the reduction of the applied dose of antifungal compounds. This specialist agriculture expands the choice of the most appropriate solution for his private problems.

At the same time, some of these tools are limited when in some cultures there are cases of phytotoxicity.

Thus, the aim of the invention is to propose a new fungicidal composition having better selectivity even in those cultures that call is up sensitive, keeping the same biological activity in respect to the prevention or treatment of various diseases.

In the present work it was found that the above objectives can be achieved by using the composition according to the invention.

The object of the present invention is a fungicidal composition suitable for the treatment of fungal diseases of crops on the basis of at least one fungicidal compound and at least one special type additives oils of plant origin with a high potential for drying, the latter acts as an activator (stimulating agent). The invention also concerns a method of treating crops, pursuing the same goal.

From the literature known quite a lot of examples of using vegetable oils in the composition of the pesticide and, in particular fungicidal compositions.

However, never reported use in fungicidal compositions of vegetable oils with a high potential for drying.

Totally unexpected, and such use in fungicidal compositions according to the invention is allowed to obtain extremely promising results.

Fungicidal compositions according to the invention for the most part well-known experts on agriculture, in particular because of their efficiency is Yunosti against diseases affecting or likely to affect cereal and other crops.

In respect of the application of some vegetable oils was also noted their advantage is that they allow three times to reduce the dose of the oil, keeping the same biological effectiveness.

Along with this composition the proposed composition allows to obtain excellent physical properties of the used slurry and thus creates the possibility of its application with various other finish combinations without the risk of physico-chemical incompatibilities.

This stability of the applied slurry fungicidal compositions according to the invention can also be used in the composition of some active materials, which in other cases is difficult, and sometimes impossible to introduce into the composition.

Another object of the invention is to offer a new fungicide combinations suitable for the prevention or treatment of disease.

Another objective of the invention is to offer a fungicidal combination with improved efficacy as a prophylactic or therapeutic agent against various diseases and/or improved selectivity.

Another objective of the invention is to improve the fungicidal action of the compositions with respect to its duration.

Another objective of the invention is to offer combines the th, providing the best resistance to adverse weather conditions, particularly rain.

In an unexpected way was found fungicidal composition that permits all or part of the above-mentioned problems and drawbacks.

The fungicidal composition according to the invention is characterized in that it contains at least one fungicidal compound a and at least one oil, vegetable-based and has a high potential for drying.

The advantages of selective application of vegetable oils with a high potential for drying, are, in particular, their non-toxic or at least reduced toxicity compared with oils of mineral origin, reduced phytotoxicity and higher Biodegradability.

According to one of the most profitable options for implementing fungicidal compositions according to the invention, the fungicidal compound And selected from dicarboximide derivatives.

Of these dicarboximide derivatives are particularly preferred those that belong to the group, including Captan, captafol, chlozolinate, iprodione, procymidone, vinclozolin.

Preferred fungicidal compound And is iprodion.

The invention relates, therefore, to fungicidal compositions comprising oil bodies the practical phase, which is chosen from unsaturated vegetable oils, isomerizing oil, a complex ester of vegetable oil, a polymer of plant origin and/or mixtures of these different organic phases.

Vegetable oil can be of different origin, but the preferred vegetable oil derived from flax, sunflower, corn, soybean, cotton, safflower and canola. These oils are available in the form of oils of different categories, namely in the form of crude, refined or isomerized oils.

The preferred oil is a polyunsaturated vegetable oil, which in its natural form has a significant number of unsaturated bonds.

Under polyunsaturated oil mean triglyceride, a large part of the normal fatty chains which have two or three double bonds and are denoted C18:2 or C18:3, i.e. the circuit is composed of 18 carbon atoms with 2 or 3 nenasyshchennosti.

As an example, polyunsaturated oils can be called triglycerides, which mainly contain fatty chain, called linolenic (C18:3), such as linseed oil. For information, the weight composition of this oil, expressed in fatty acids, can have the following limits: 50 to 60% C18:3, from 10 to 17% C18:2, 15 to 25% C18:1, from 2 to 4% C18:0 and 5 to 8% C16:0.

As an example, polyunsaturated oils may be called triglycer is s, contains mostly fatty chain linolenic type (C18:2), such as sunflower, corn, soybean, safflower, cotton and canola. For information, the composition of these oils, expressed in fatty acids, can have the following range: from 45 to 70% C18:2, from 0.1 to 10% C18:3, from 10 to 40% C18:1, from 0.1 to 10% C18:0 and from 1 to 26% C16:0.

In other words, the oil included in the scope of the present invention, is called drying. The ability to drying is either natural drying or poluvysyhayuschee oil), or it occurs as a result of chemical processing oil having a low capacity for drying or non-drying oils (oils, called semidrying or non-drying) - in this case, the oil is called samaritanism.

The isomerization reaction is the conjugation of double bonds in chain fatty acids-CH=CH-CH2-CH=CH - with the aim of obtaining the following conjugated dienes: -CH=CH-CH=CH-CH2-, which increases their ability to drying (the ability to react with air).

As an example isomerizing oil can be called samaritano sunflower oil with a content of conjugated dienes in the range from 16 to 18%, and samaritano linseed oil, containing from 11 to 13% of conjugated dienes.

For fungicidal compositions according to the invention is preferably used vegetable oils have iodine Chi is lo, associated with the ability to drying, above 70, preferably above 90, even more preferably above 130 and, in a particularly preferred case, above 150.

The present invention relates also to a combination of compounds a and b - this combination is a combination of two components and can be applied in the form of ready-to-use mixture and in the form of a mixture, prepared immediately before use.

The weight ratio of the connection/connection And in the composition of the invention typically range from 0.15 to 1.6, mostly from 0.2 to 1.35, preferably from 0.25 to 1, or from 0.3 to 0.7, and in the particularly preferred case, this ratio is equal to 0.45.

This composition is suitable for treatment of fungal diseases in various crops. It is effective, therefore, for the treatment of diseases such as rust, rynchospora, Helminthosporium barley; to ensure lodging, different kinds of rye, septoriosis, Helminthosporium and fusariosis wheat. The composition is also effective against Botrytis, Alternaria, Sclerotinia, Helminthosporium and Fusarium protein and oilseed crops (in particular, peas, canola and corn), and for treatment of diseases of turf grass, such as mildew, Fusarium, Sclerotinia and risotto.

The composition is particularly suitable for the treatment of gray rot of grape vines, vegetable cool the tour, peaches, almonds, apples, pears, canola, peas, beans and citrus; alternariosis vegetables, peaches, almonds, apples, pears, rape, potatoes and citrus; Monrose peaches, almonds, cherries, Sclerotinia vegetable crops, canola and potatoes; and Rhizoctonia vegetables and rice.

Contained in the composition according to the invention compounds As described in at least one of the following two works:

- "The pesticide manual", published by Clive TOMLIN and published by the British Crop Protection Council, 11th edition;

- Index phytosanitaire (Phytosanitary pointer) 2000, published by the Association de Coordination Technique Agricole (Association of agricultural technical coordination), 36th edition.

Connection, also contained in the composition according to the invention is mainly refined or samaritanism sunflower oil.

When the practical application of the compounds and compositions according to the invention are rarely used individually.

The compounds a and b in the above fungicidal compositions according to the invention often comprise from 0.5 to 95 wt.%. this composition.

Can be used concentrated composition, i.e. the industrial product that combines two active substances (in the framework of this text under the active substance should be understood as the compound a, which is fungicidal connection and connection - especially the Yu additive). Can also be used diluted composition, ready for spraying to be processed culture.

In the latter case, the dilution water can be produced either in a concentrated industrial composition containing the two active substances (this mixture is called "ready to use" or in English "ready mix"), or by mixing immediately before use (called by the English "tank mix") two concentrated industrial compositions, each of which contains one substance.

The composition according to the invention is liquid and is in the form of a solution, suspension, emulsion or suitable for emulsification of the concentrate. Liquid oil-in-water compositions are preferred because of ease of use, and due to the simplicity of their preparation. Preference is given to working with concentrated aqueous suspension with the use of vegetable oils in the form of an emulsion of the type oil-in-water".

Often the composition according to the invention may include any solid or liquid additives used in conventional methods of preparation of compounds of phytosanitary products.

The composition according to the invention may furthermore contain all normal for phytosanitary compositions additives, in particular carriers, surfactants, adhesives and thinning agents, antifreezes. This composition may also in order to contain any other ingredients, such as protective colloids, adhesives, thickeners, thixotropic agents, impregnating agents, stabilizers, chelating agents, pigments, dyes, polymers, protivovspenivayushchie agents.

The term "media" in this statement is denoted by organic or mineral, natural or synthetic material with which the active substance is combined to facilitate the application of the latter on the plant. This carrier is therefore inert and should be acceptable for agriculture, in particular on the treated plant. The carrier can be solid (clays, natural or synthetic silicates, silica, resins, waxes, solid fertilizers, and the like) or liquid (water, alcohols, ketones, petroleum fractions, aromatic or paraffinic hydrocarbons, chlorinated hydrocarbons, liquefied gases, etc).

Surface-active agent may be an emulsifying, dispersing or wetting agent of ionic or nonionic type. As example can be mentioned salts of polyacrylic acids, salts of lignosulphonic acids, salts of Phenolsulphonic or naphthalenesulphonic acid, the polycondensation products of ethylene oxide with fatty alcohols or fatty acids or fatty amines, substituted phenols (in particular ALKYLPHENOLS or kilfenora), salts of esters sulfonating acid derivative taurine (in particular alliterate), phosphate esters of alcohols or polyoxyethylene phenols. Preferably the presence of at least one surface-active agent, because it promotes the dispersion of the active substances in water and their convenient application to plants.

Under the concentrated oil-in-water suspension means suspension in water, the mass of which are solid active substance in the form of crystals, suspended in water and in organic oil phase, in this case in vegetable oil with an emulsifier in an emulsion oil-in-water".

Concentrated suspensions, also suitable for spraying, are prepared so as to obtain a stable fluid product which is not subjected to thickening or formation of a precipitate after storage or separation of the phases. They usually contain from 10 to 75% of active substances, from 0.5 to 15% of surface-active agents, from 0.1 to 10% of thixotropic agents, from 0 to 10% of suitable additives such as pigments, colorants, antifoams, corrosion inhibitors, stabilizers, impregnating agents, adhesive agents, and as carrier, water or any organic liquid in which the active substance is little or no soluble.

Some solid organic materials or mineral salts can be dissolved or dispersed in the carrier to operatlonal sedimentation, or as antifreeze for the water.
