novel active ingredients of the formula I are manufactured and used will be apparent from the following examples.

Manufacturing examples

Example 1

1-(Ethoxyamino)-2-(hydrazino)-ethane-1,2-dione

A solution of 234 g (1.59 mol) of methyl (ethoxyamino)-oxoacetate in 450 ml of ethanol was added to a solution of 92.8 g (1.855 mol) of hydrazine hydrate in 300 ml of ethanol and the mixture was stirred for 2 hours at 65.degree. C. The mixture was cooled to +10.degree. C., the precipitate was suction filtered, washed with a small amount of cold ethanol, and dried. There was obtained 150 g (64.2% of theory) of 1-(ethoxyamino)-2-(hydrazino)-ethane-1,2-dione as white crystals of m.p. 182.degree. C.

Example 2

1-(Ethoxyamino)-2-[(4-chlorophenylmethylene)-hydrazino]-ethane-1,2-dione

9 g (0.07 mol) of 4-chlorobenzaldehyde was added to a solution of 10.3 g (0.07 mol) of 1-(ethoxyamino)-2-(hydrazino)-ethane-1,2-dione (Example 1) in 100 ml of acetic acid, and the mixture was stirred for 30 minutes at 40.degree. C. The precipitate was suction filtered, washed with ether and dried. There was obtained 12.2 g (65% of theory) of 1-(ethoxyamino)-2-[4-chlorophenylmethylene)-hydrazino]-ethane-1,2-dione as white crystals of m.p. 330.degree. C. (decomp.).

In general terms, the novel compounds are extremely effective on a broad spectrum of phytopathogenic fungi, in particular those from the class consisting of the Ascomycetes and Basidiomycetes. Some of them have a systemic action and can be used as foliar and soil fungicides.

The fungicidal compounds are of particular interest for controlling a large number of fungi in various crops or their seeds, especially wheat, rye, barley, oats, rice, Indian corn, lawns, cotton, soybeans, coffee, sugar cane, fruit and ornamentals in horticulture and viticulture, and in vegetables such as cucumbers, beans and cucurbits.

The novel compounds are particularly useful for controlling the following plant diseases:

Erysiphe graminis in cereals, Erysiphe cichoracearum and Sphaerotheca fuliginea in cucurbits, Podosphaera leucotricha in apples, Uncinula necator in vines, Puccinia species in cereals, Rhizoctonia solani in cotton, Ustilago species in cereals and sugar cane, Venturia inaequalis (scab) in apples, Helminthosporium species in cereals, Septoria nodorum in wheat, Botrytis cinerea (gray mold) in strawberries and grapes, Cercospora arachidicola in groundnuts, Pseudocercosporella herpotrichoides in wheat and barley, Pyricularia oryzae in rice, Phytophthora infestans in potatoes and tomatoes, Fusarium and Verticillium species in various plants, Plasmopara viticola in grapes, Alternaria species in fruit and vegetables.

The compounds are applied by spraying or dusting the plants with the active ingredients, or treating the seeds of the plants with the active ingredients. They may be applied before or after infection of the plants or seeds by the fungi.

The novel substances can be converted into conventional formulations such as solutions, emulsions, suspensions, dusts, powders, pastes and granules. The application forms depend entirely on the purposes for which they are intended; they should at all events ensure a fine and uniform distribution of the active ingredient. The formulations are produced in known manner, for example by extending the active ingredient with solvents and/or carriers, with or without the use of emulsifiers and dispersants; if water is used as solvent, it is also possible to employ other organic solvents as auxiliary solvents. Suitable auxiliaries for this purpose are solvents such as aromatics (e.g., xylene), chlorinated aromatics (e.g., chlorobenzenes), paraffins (e.g., crude oil fractions), alcohols (e.g., methanol, butanol), ketones (e.g., cyclohexanone), amines (e.g., ethanolamine, dimethylformamide), and water; carriers such as ground natural minerals (e.g., kaolins, aluminas, talc and chalk) and ground synthetic minerals (e.g., highly disperse silica and silicates); emulsifiers such as nonionic and anionic emulsifiers (e.g., polyoxyethylene fatty alcohol ethers, alkyl sulfonates and aryl sulfonates); and dispersants such as lignin-sulfite waste liquors and methylcellulose.

The fungicidal agents generally contain from 0.1 to 95, and preferably from 0.5 to 90, wt % of active ingredient. The application rates are from 0.02 to 3 kg or more of active ingredient per hectare, depending on the type of effect desired. The novel compounds may also be used for protecting materials, e.g., on Paecilomyces variotii.

When the active ingredients are used for treating seed, rates of from 0.001 to 50, and preferably from 0.01 to 10, g of active ingredient per kg of seed are generally required.

The agents and the ready-to-use formulations prepared from them, such as solutions, emulsions, suspensions, powders, dusts, pastes and granules, are applied in conventional manner, for example by spraying, atomizing, dusting, scattering, dressing or watering.

Examples of formulations are given below.

Use Example 1

Action on Fusarium culmorum in wheat

True leaves of pot-grown wheat seedlings of the "Kanzler" variety were sprayed to runoff with aqueous spray liquors containing (dry basis) 80% of active ingredient and 20% of emulsifier. The next day they were inoculated with a spore suspension of Fusarium culmorum and placed in a climatic chamber of high humidity (>90%) at 22.degree.-24.degree. C. The extent of fungus spread was assessed visually after 6 days.

The results of this experiment show that compounds nos. 9, 10, 14, 27, 31, 35, 41, 45, 46 and 47, when applied as spray liquors containing 500 ppm of active ingredient, have an excellent fungicidal action (10% attack).

Use Example 2

Action on Botrytis cinerea

Paprika seedlings of the "Neusiedler Ideal Elite" variety were sprayed, after 4 to 5 leaves were well developed, to runoff with aqueous suspensions containing (dry basis) 80% of active ingredient and 20% of emulsifier. After the sprayed-on layer had dried, the plants were sprinkled with a conidial suspension of the fungus Botrytis cinerea, and placed at 22.degree. to 24.degree. C. in a chamber of high humidity. After 5 days, the disease had spread to such a great extent on the untreated plants that the necroses covered the major portion of the leaves.

The results of this experiment show that compounds nos. 7, 22, 24, 26, 31, 42, 45 and 46, when applied as spray liquors containing 500 ppm of active ingredient, have a better fungicidal action (10% attack) than prior art active ingredient A (60% attack).
