Sooted all, they can be used to deal with such phytopathogenic fungi, as Plasmodiophoromycetes, Oomycetes, Chytridiomycota, Zygomycetes, Ascomycetes, Basidiomycetes, Deuteromycetes, and others.

Particularly successful they can be used to combat such diseases of cereal crops, as Erysiphe, Cochliobolus, Pyrenophora, Rhynchosporium, Septoria spp. , Fusarium spp., Pseudocercosporella and Leptosphaeria, as well as to combat fungal lesions such Nazarovich cultures, as the vine, fruit and vegetable crops, it may be, for example, Phytophtora, Plasmopara, Pythium, and pathogens true powdery mildew, for example Spherotheca or Uncinula, and these pathogens leaf spots, as Venturia, Altemaria and Septoria, and Rhizoctonia, Botrytis, Sclerotinia and Sclerotium.

Presents the composition of the active compounds are well tolerated by plants necessary to combat plant diseases concentrations, which allows for the processing of ground parts of plants, seedlings and planting material and soil.

Corresponding to the invention the composition of the active substances can be converted to conventional preparative forms such as solutions, emulsions, suspensions, powders, foams, pastes, granules, aerosols, can produce finely dispersed encapsulated drugs in polymeric membranes, they can also enter the I.

These preparative forms prepared by known methods, for example by mixing the active principles or compositions of the active principles with diluents, i.e. liquid solvents, pressurized liquefied gases and/or solid carriers optionally with the possible use of surface-active agents, including emulsifying means and/or dispersing means and/or blowing means. In the case of use as diluent water can be applied, for example, and organic solvents as additional solvents (solubilization). In the role of liquid solvents can be mainly such aromatic compounds as xylene, toluene or alkylnaphthalenes, and chlorinated aromatics or chlorinated aliphatic hydrocarbons, such as chlorobenzene, chloroethylene or methylene chloride, aliphatic hydrocarbons such as cyclohexane or paraffins, for example products of the distillation of crude oil, alcohols such as butanol or glycol and also their ethers and esters, ketones such as acetone, methyl ethyl ketone, methyl isobutyl ketone or cyclohexanone, solvents with high polyaramid or substances carriers understand such fluid, which at normal temperature and under normal pressure are in the gaseous state. This is, for example, propellants for aerosol compounds such as halogen-substituted hydrocarbons as well as butane, propane, nitrogen and carbon dioxide. As solids carriers can be used, for example, crushed rocks, such as kaolin, alumina, talc, chalk, quartz, attapulgite, montmorillonite or infusoria earth, and ground synthetic minerals such as highly disperse silicic acid, alumina and silicates. As solids carriers for granular preparative forms can be, for example, crushed and fractionated natural minerals such as calcite, marble, pumice, thick, dolomite, and synthetic granules on the basis of inorganic and organic crushed materials, and granules of organic materials such as wood flour, coconut husks, corn cobs and tobacco stalks. As emulsifying and/or foam-forming means can be, for example, nonionic and anionic emulsifiers, such as esters of fatty acids and oxides, ethers of fatty alcohols and the floor is also protein hydrolysates. Dispersing means can be, for example, ligninase sulfite liquor and methylcellulose.

To improve the adhesion of the composition of preparative forms can be entered, for example, carboxymethylcellulose, natural and synthetic powdered, granular or latex polymers, such as gum Arabic, polyvinyl alcohol, polyvinyl acetate, and also natural phospholipids, such as Catalina and lecithins, and synthetic phospholipids. As other additives can be mineral and vegetable oils.

Can find the use of such dyes, inorganic pigments, for example iron oxide, titanium oxide, blue ferrocyanides, and organic dyes such as alizarin and metallophthalocyanine dyes, azo dyes, and trace elements such as salts of iron, manganese, boron, copper, cobalt, molybdenum and zinc.

Practical application based on normal operations, it may be, for example, pouring, sprinkling, spraying, spraying, dusting, wet or dry etching compositions, solutions or suspensions, and inlaying.

When the processing of individual parts of plants the concentration of active substance in ready-to-use forms can vary within wide limits. In General, these concentrations are in the range from 1 to 0.0001 wt.%, preferably from 0.5 to 0.001 wt.%.

In the General case for processing of seed material of the active substance is taken in an amount of from 0.001 to 50 g per kilogram of seed, preferably from 0.01 to 10 g

Soil concentrations of active substances should be from 0.00001 to 0.1 wt.%, preferably from 0.0001 to 0.02 wt.% at the site of action.

While the individual active substances show high enough fungicidal activity, their compositions to demonstrate the performance, which goes beyond the simple sum of efficiencies.

The synergistic effect of fungicides present in those cases lisovanych active substances.

The expected effectiveness of this combination of two active compounds can be calculated as follows (Colby, S. R., "Calculating Synergistic and Antagonistic Responses of Herbicide Combinations", Weeds 15, pages 20-22, 1967):

if

X is expressed as a percentage relative to the untreated control plants, the degree of efficacy when using active compound a at a concentration of m ppm,

Y means expressed as a percentage relative to the untreated control plants, the degree of efficiency in the use of the active substance B in a concentration of n ppm,

E. means expressed as a percentage relative to the untreated control plants, the expected degree of efficiency in the use of the active substance and the active substance B in a concentration of respectively m and n ppm,

then

If experimentally established fungicidal activity exceeds the calculated, then the activity of the composition vergadain and this means that we are dealing with synergies. In this case, observed in the experiment, the degree of efficiency should be higher than calculated by the above formula is the expected degree effectiverate compositions of active substances exceeds the calculated value, and this confirms the synergistic effect.
