Definitions

• the invention relates to the use of fungicidal compositions containing prothioconazoles and tebuconazoles for dressing seeds.
• the fungicidal action of the active compound combinations which can be used according to the invention in the treatment of seeds is considerably higher than the sum of the actions of the individual active compounds. So there is an unforeseeable, real synergistic effect and not just an addition.
• Prosthioconazoles and their use as fungicides are known (cf. WO 96-16 048).
• This active ingredient is 2- [2- (l-chlorocyclopropyl) -3- (2-chlorophenyl) -2-hydroxypropyl] -2,4-dihydro [l, 2,4] triazol-3-thione , both in the "Thiono" form of the formula
• Tebuconazole and its use as a fungicide are also known (cf. EP-A 0 040 345).
• This active ingredient is the tnazole devat of the formula
• the active compounds are present in the active compound combinations which can be used according to the invention in certain weight ratios, the synergistic effect is particularly evident.
• the weight ratios of the active ingredients in the active ingredient combinations can be varied within a relatively wide range. In general, 1 to 1 part by weight of prothioconazole accounts for 0.01 to 100 parts by weight, preferably 0.05 to 20 parts by weight, of tebuconazole.
• the active substance combinations which can be used according to the invention can also contain further active substances.
• the active substance combinations which can be used according to the invention have very good fungicidal properties and can be used to combat phytopathogenic fungi, such as plasmidiophoromycetes, Oomycetes, Chyt ⁇ diomycetes, Zygomycetes, Ascomycetes, Basidiomycetes, Deuteromycetes etc. They are particularly suitable for combating cereal diseases such as Tilletia, Ustilago and Fusanum.
• the active compound combinations which can be used according to the invention can be converted into the customary mordant formulations, such as solutions, emulsions, suspensions, powders, foams, slurries or other coating compositions for seeds, and TLV formulations.
• customary mordant formulations such as solutions, emulsions, suspensions, powders, foams, slurries or other coating compositions for seeds, and TLV formulations.
• customary additives such as, for example, customary extenders and solvents or diluents, dyes, wetting agents, dispersants, emulsifiers, defoamers, preservatives, secondary thickeners, adhesives, gibberellins and also water.
• Suitable dyes which can be contained in the mordant formulations which can be used according to the invention are all dyes customary for such purposes. Both pigments that are sparingly soluble in water and dyes that are soluble in water can be used. Examples include those under the names Rhodarr ⁇ n B, C.I. Pigment Red 112 and C.I. Solvent Red 1 known dyes.
• Suitable wetting agents which can be contained in the mordant formulations which can be used according to the invention are all substances which are customary for the formulation of agrochemical active substances and which promote wetting.
• Alkyl naphthalene sulfonates such as diisopropyl or diisobutyl naphthalene sulfonates, can preferably be used.
• Suitable dispersants and / or emulsifiers which may be present in the mordant formulations which can be used according to the invention are all nonionic, anionic and cationic dispersants customary for the formulation of agrochemical active ingredients.
• Nonionic or anionic dispersants or mixtures of nonionic or anionic dispersants can preferably be used.
• Suitable nonionic dispersants include, in particular, ethylene oxide / propylene oxide block polymers, alkylphenol polyglycol ethers and tristryrylphenol polyglycol ethers and their phosphated or sulfated derivatives.
• Suitable anionic dispersants are, in particular, lignin sulfonates, polyacrylic acid salts and aryl sulfonate-formaldehyde condensates.
• the mordant formulations which can be used according to the invention can contain, as defoamers, all of the foam-inhibiting substances which are customary for formulating active agrochemicals. Silicone defoamers and magnesium stearate can preferably be used.
• All substances which can be used for such purposes in agrochemical compositions can be present as preservatives in the mordant formulations which can be used according to the invention.
• Examples include dichlorophene and benzyl alcohol hemiform.
• the secondary thickeners which can be contained in the mordant formulations which can be used according to the invention are all used for such purposes in agrochemical compositions usable substances in question.
• Cellulose derivatives, acrylic acid derivatives, xanthan, modified clays and highly disperse silica are preferred.
• Suitable adhesives which can be contained in the mordant formulations which can be used according to the invention are all binders which are customarily used in mordants.
• Polyvinylpyrrolidone, polyvinyl acetate, polyvinyl alcohol and tylose are preferred.
• Substances of the formula are preferably used as gibberellins which can be contained in the mordant formulations which can be used according to the invention
• R represents a hydrogen atom or a hydroxy group
• gibberellins of the formula (III) are:
• the mordant formulations which can be used according to the invention can be used either directly or after prior dilution with water to treat cereal seeds of the most varied ax.
• the concentrates or the preparations obtainable therefrom by dilution with water can be used for dressing the seeds of wheat, barley, rye, oats, millet, spelled, triticale, corn and rice.
• the seed dressing formulations which can be used according to the invention or their diluted preparations can also be used for dressing seeds of transgenic plants. In cooperation with the substances formed by expression, additional synergistic effects can also occur.
• the dressing is carried out by placing the seed in a mixer, adding the desired amount of dressing formulation either as such or after prior dilution with water and mixing until the formulation is uniformly distributed on the seed. If necessary, a drying process follows.
• the application rate of the mordant formulations which can be used according to the invention can be varied within a relatively wide range. It depends on the respective content of the active ingredients in the formulations and on the seeds.
• the application rates of active ingredient combination are generally between 0.001 and 50 g per kilogram of seed, preferably between 0.01 and 15 g per kilogram of seed.
• Fungicides always have a synergistic effect if the fungicidal activity of the active ingredient combinations is greater than the sum of the effects of the individually applied active ingredients.
• X means the efficiency when using the active ingredient A in an application rate of m g / 100 kg
• Y means the efficiency when using the active ingredient B in an application rate of n g / 100 kg
• E means the efficiency when using active ingredients A and B in application rates of rn and n g / 100 kg
• the efficiency is determined in%. It means 0% an efficiency that corresponds to that of the control, while an efficiency of 100% means that no infection is observed.
• the combination of the combination is superadditive, ie there is a synergistic effect.
• the actually observed efficiency may be greater than the value for the expected efficiency (E) calculated from the above formula.
• the active ingredients or the combination of active ingredients are used in such a way that commercially available liquid stains of the individual active ingredients or the combination of active ingredients are used.
• the infected seed is shaken for 3 minutes with the respective dressing agent in a sealed plastic container.
• the plants are evaluated for symptoms 3 weeks after sowing.
• the effectiveness is expressed in percent. 0% means an efficiency that corresponds to that of the control, while an efficiency of 100% means that no infection is observed.
