The novel compounds of the formula I are suitable as fungicides.
The novel compounds, or the compositions containing them, can be applied by spraying, atomizing, dusting, scattering or watering in the form of directly sprayable solutions, powders, suspensions, even high-percentage aqueous, oily or other suspensions or dispersions, emulsions, oil dispersions, pastes, dusting compositions, scattering compositions or granules. The application forms depend on the intended uses; in each case they should if possible ensure the finest dispersion of the active compounds according to the invention.
Normally, the plants are sprayed or dusted with the active compounds or the seeds of the plants are treated with the active compounds.
The formulations are prepared in a known manner, eg. by extending the active compound with solvents and/or carriers, if desired using emulsifiers and dispersants, where if water is used as a diluent other organic solvents can also be used as auxiliary solvents. Suitable auxiliaries for this purpose are mainly: solvents such as aromatics (eg. xylene), chlorinated aromatics (eg. chlorobenzenes), paraffins (eg. petroleum fractions), alcohols (eg. methanol, butanol), ketones (eg. cyclohexanone), amines (eg. ethanolamine, dimethylformamide) and water; carriers such as ground natural minerals (eg. kaolins, aluminas, talc, chalk) and ground synthetic minerals (eg. highly disperse silica, silicates), emulsifiers such as nonionic and anionic emulsifiers (eg. polyoxyethylene fatty alcohol ethers, alkanesulfonates and arylsulfonates) and dispersants such as lignin-sulfite waste liquors and methylcellulose.
Suitable surface-active substances are the alkali metal, alkaline earth metal and ammonium salts of aromatic sulfonic acids, eg. lignosulfonic, phenolsulfonic, naphthalenesulfonic and dibutylnaphthalenesulfonic acid, and also of fatty acids, alkyl- and alkylarylsulfonates, alkyl-, lauryl ether and fatty alcohol sulfates, as well as salts of sulfated hexa-, hepta- and octade-canols, and also of fatty alcohol glycol ethers, condensation products of sulfonated naphthalene and its derivatives with formaldehyde, condensation products of naphthalene or of the naphthalenesulfonic acids with phenol and formaldehyde, polyoxyethylene octylphenol ether, ethoxylated isooctyl-, octyl- or nonylphenol, alkylphenol or tributylphenylpolyglycol ethers, alkylaryl polyether alcohols, isotridecyl alcohol, fatty alcohol ethylene oxide condensates, ethoxylated castor oil, polyoxyethylene or polyoxypropylenealkyl ethers, lauryl alcohol polyglycol ether acetate, sorbitol esters, lignin-sulfite waste liquors or methylcellulose.
Powder, scattering and dusting compositions can be prepared by mixing or joint grinding of the active substances with a solid carrier.
Granules, eg. coated, impregnated and homogeneous granules, can be prepared by binding the active compounds to solid carriers. Solid carriers are mineral earths such as silica gel, silicic acids, silicates, talc, kaolin, limestone, lime, chalk, bole, loess, clay, dolomite, diatomaceous earth, calcium sulfate and magnesium sulfate, magnesium oxide, ground synthetic materials, fertilizers, such as ammonium sulfate, ammonium phosphate, ammonium nitrate, ureas and vegetable products, such as cereal flour, tree bark meal, wood meal and nutshell meal, cellulose powder or other solid carriers.

Examples of such preparations are:
I a solution of 90 parts by weight of the compound No. I.003 and 10 parts by weight,of N-methyl-.alpha.-pyrrolidone, which is suitable for application in the form of very small drops;
II. a mixture of 20 parts by weight of the compound No. I.007, 80 parts by weight of xylene, 10 parts by weight of the addition product of from 8 to 10 mol of ethylene oxide to 1 mol
of oleic acid N-monoethanolamide, 5 parts by weight of calcium salt of dodecylbenzenesulfonic acid, 5 parts by weight of the addition product of 40 mol of ethylene oxide to 1 mol of castor oil; a dispersion is obtained by finely dispersing the solution in water.
III. an aqueous dispersion of 20 parts by weight of compound No. I.012, 40 parts by weight of cyclohexanone, 30 parts by weight of isobutanol, 20 parts by weight of the addition product of 40 mol of ethylene oxide to 1 mol of castor oil;
IV. an aqueous dispersion of 20 parts by weight of the compound No. I.001, 25 parts by weight of cyclohexanol, 65 parts by weight of a petroleum fraction of boiling point from 210 to 280.degree. C., and 10 parts by weight of the addition product of 40 mol of ethylene oxide to 1 mol of castor oil;
V. a mixture, ground in a hammer mill, of 80 parts by weight of the compound No. I.011, 3 parts by weight of the sodium salt of diisobutylnaphthalene-.alpha.-sulfonic acid, 10 parts by weight of the sodium salt of a lignosulfonic acid from a sulfite waste liquor and 7 parts by weight of powdered silica gel; a spray liquor is obtained by finely dispersing the mixture in water;
VI. an intimate mixture of 3 parts by weight of the compound No. I.009 and 97 parts by weight of finely divided kaolin; this dusting composition contains 3% by weight of active compound;
VII. an intimate mixture of 30 parts by weight of the compound No. I.002, 92 parts by weight of powdered silica gel and 8 parts by weight of liquid paraffin which has been sprayed onto the surface of this silica gel; this preparation gives the active compound a good adhesion;
VIII. a stable aqueous dispersion of 40 parts by weight of the compound No. I.005, 10 parts by weight of the sodium salt of a phenolsulfonic acid/urea/formaldehyde condensate, 2 parts by weight of silica gel and 48 parts by weight of water, which can be further diluted;
IX. a stable oily dispersion of 20 parts by weight of the compound No. I.010, 2 parts by weight of the calcium salt of dodecylbenzenesulfonic acid, 8 parts by weight of fatty alcohol polyglycol ether, 20 parts by weight of the sodium salt of a phenolsulfonic acid/urea/formaldehyde condensate and 68 parts by weight of a paraffinic mineral oil.
The novel compounds I are distinguished by an outstanding activity against a broad spectrum of phytopathogenic fungi, in particular from the class of Ascomycetes and Basidiomycetes. They are systemically active in some cases and can be employed as foliar and soil fungicides.
They are of particular importance for the control of a multiplicity of fungi on various crop plants such as wheat, rye, barley, oats, rice, corn, grass, cotton, soybeans, coffee, sugar cane, grapes, fruit and decorative plants and vegetable plants such as cucumbers, beans and cucurbits, and on the seeds of these plants.
The compounds are applied by treating the fungi or the seeds, plants, materials or the soil to be protected from fungal attack with a fungicidally effective amount of the active compounds.
They are applied before or after the infection of the materials, plants or seeds by the fungi.
The novel compounds are specifically suitable for the control of the following plant diseases:
Erysiphe graminis (powdery mildew) in cereals, Erysiphe cichoracearum and Sphaerotheca fuliginea on cucurbits, Podosphaera leucotricha on apples, Uncinula necator on vines, Puccinia species on cereals, Rhizoctonia species on cotton and lawns, Ustilago species on cereals and sugar cane, Venturia inaequalis (scab) on apples, Helminthosporium species on cereals, Septoria nodorum on wheat, Botrytis cinerea (gray mold) on strawberries, vines, decorative plants and vegetables, Cercospora arachidicola on ground-nuts, Pseudocercosporella herpotrichoides on wheat, barley, Pyricularia oryzae on rice, Phytophthora infestans on potatoes and tomatoes, Fusarium and Verticillium species on various plants, Plasmopara viticola on vines, Alternaria species on vegetables and fruit.
The novel compounds can also be employed in the protection of materials (preservation of wood), eg. against Paecilomyces variotii.
The fungicidal compositions in general contain from 0.1 to 95, preferably from 0.5 to 90, % by weight of active compound
Depending on the type of effect desired, the application rates are from 0.01 to 2.0 kg of active compound per ha.
In seed treatment, amounts of active compound of from 0.001 to 50 g, preferably 0.01 to 10 g, per kilogram of seed are in general needed.

Use examples
It was possible to show the fungicidal action of the compounds of the general formula I by the following tests:
The active compounds were prepared as a 20% strength emulsion in a mixture of 70% by weight of cyclohexanol, 20% by weight of Nekanil.RTM. LN (Lutensol.RTM. AP6, wetting agent having emulsifier and dispersant action based on ethoxylated alkylphenols) and 10% by weight Emulphor.RTM. EL (Emulan.RTM. EL, emulsifier based on ethoxylated fatty alcohols) and diluted with water according to the concentration desired.
1. Botrytis cinerea
Paprika seedlings of the variety Neusiedler Ideal Elite having 4-5 well-developed leaves were sprayed until dripping wet with an aqueous active compound suspension. After the spray coating had dried on, the plants were sprayed with a conidia suspension of the fungus Botrytis cinerea. After 5 days at 22.degree. C.-24.degree. C. and high atmospheric humidity, the fungal attack on the leaves was assessed.
In this test, the plants treated with 500 ppm of the compounds I.001, I.004, I.005, I.006 and I.007 showed 15% and less attack, while in the case of the untreated plants 65% of the leaf surfaces were attacked.
2. Plasmopara viticola
Leaves of potted vines of the variety M uller-Thurgau were sprayed until dripping wet with an aqueous active compound suspension. After 8 days in the greenhouse, the plants were infected with a zoospore suspension of Plasmopara viticola (vine Peronospora). The plants were then first kept at 24.degree. C. and 100% atmospheric humidity for 48 hours and then at 20.degree. C.-30.degree. C. for 5 days in a greenhouse. The plants were then again kept at 24.degree. C. and 100% atmospheric humidity for 16 hours before assessment of the attack.
In this test, the plants treated with 250 ppm of the compound I.005 showed 5% attack, while in the case of the untreated plants 70% of the leaf undersides were attacked.
3. Insecticidal action
It was possible to show the insecticidal action of the compounds of the general formula I by the following tests:
The active compounds were prepared
a)
as a 0.1% strength solution in acetone or
b) as a 10% strength emulsion in a mixture of 70% by weight of cyclohexanone, 20% by weight of Nekanil.RTM. LN (Lutensol.RTM. AP6, wetting agent having emulsifier and dispersant action based on ethoxylated alkylphenols) and 10% by weight of Emulphor.RTM. EL (Emulan.RTM. EL, emulsifier based on ethoxylated fatty alcohols)
and diluted with acetone in the case of (a) or with water in the case of (b) according to the desired concentration.
After conclusion of the tests, the lowest concentration at which the compounds still caused an 80-100% inhibition or mortality in comparison with untreated control tests was determined in each case (activity threshold or minimum concentration).
It was possible to show the insecticidal action of the compounds of the general formula VI by the following tests:
The active compound VI.07 was prepared
a) as a 0.1% strength solution in acetone or
b) as a 10% strength emulsion in a mixture of 70% by weight of cyclohexanone, 20% by weight of Nekanil.RTM. LN (Lutensol.RTM. AP6, wetting agent having emulsifier and dispersant action based on ethoxylated alkylphenols) and 10% by weight of Emulphor.RTM. EL (Emulan.RTM. EL, emulsifier based on ethoxylated fatty alcohols)
and diluted with acetone in the case of (a) or with water in the case of (b) according to the desired concentration.
.alpha.) Contact test in Petri dishes with the green rice leafhopper (Nephotettix cincticeps)
Round filters of diameter 9 cm were treated with 1 cm.sup.3 of the active compound formulated as described in (b) and placed in a plastic Petri dish, having projections, of 9.4 cm diameter. 5 adult rice leafhoppers were then inserted and the Petri dish was closed.
When using the active compound in acetone solution as described in (a), the experiment was carried out in glass Petri dishes of diameter 10 cm. The filter was in this case moistened with 1 cm.sup.3 of water after evaporating the acetone.
The mortality was determined after 24 hours.
.beta.) Spray test on intact plant with the green rice leafhopper (Nephotettix cincticeps)
Rice plants about 8 cm high in plastic pots of 9 cm diameter were sprayed until dripping wet with an active compound preparation according to (b) in the spray cabin and, after drying off, placed under a plastic cylinder of diameter 13 cm and height 30 cm. 10 adult rice leafhoppers were inserted and the cylinder was closed with gauze.
The mortality was determined after 48 hours.
In both tests, beginning with 400 ppm (0.4 mg) of active compound per batch down to 100 ppm of active compound a 100% mortality was recorded with the rice leafhoppers.
