    Acylated sec-alkylanilines and acylated alkoxy-sec.alkylanilines of the formula I are valuable microbicides. They can be used in the form of compositions especially for controlling phytopathogenic fungi, such as Phytophthora, Plasmopara, Pythium, Puccinia, Cercospora, Erysiphe and others. The compounds have a systemic action.

    The invention relates to chemical plant protection agents, specifically to a fungicidal agent based on N, N-disubstituted aniline derivatives.
    A fungicide is known whose active ingredient is aniline derivatives 1.
    Chemically similar to the described compound are fungicides based on N- (1-methoxycarbonylethyl) -N-haloacetyl 2, b-dimethylaniline 2.
    However, these fungicides are not sufficiently active at low concentrations.
    The aim of the present invention is to find new fungicidal agents with high fungicidal activity.
    To achieve this goal, an agent has been proposed using compounds of general formula I as N, M-disubstituted aniline derivatives.

    Table continuation
    The forms of application of compounds of formula I are conventional: powdered and chemically applied preparations for soil application, modified, granulated with a shell, impregnated granular and homogeneous granulated preparations, granules, solutions, aerosols, wettable powders, emulsion concentrates, solution concentrates.
    Example 1. 3 week old, ground / 1 nut plants are sprayed with spraying liquid {0.03% biologically active substance). After about 12 hours, the treated plants are dusted with a suspension of conidia of the fungus. Then, the infected plants are kept for 24 hours at a relative air humidity of 90%, after which the plants are placed in a greenhouse, in which the temperature is maintained approximately. Fungus damage is assessed after 12 days.
    Compounds g ,, 31,43 completely prevent fungal infection.
    PRI ime R 2. Action against Phytophthora infestans on tomatoes. Curative action.
    After growing for three weeks, tomato plants are sprayed with a suspension of zoospores of the fungus and kept in a chamber at a temperature between 18 and saturated humidity. Moistening is stopped after 24 hours. After the plants have dried, they are sprayed with a liquid that contains a biologically active substance prepared in the form of a wetting powder in a concentration of 0.06%. After drying the applied layer of liquid, the plants are kept in a humidified chamber for 4 days. Quantity and. the size of the typical spots on the leaves after the expiration of the indicated time period serves as a measure of the activity of the test substance.
    Warning - systemic action
    Biologically active substances prepared in the wetting powder are applied in a concentration of 0.006% (based on the volume of the soil) on the soil surface with a tomato plant three weeks old. After serving for three weeks, the sides of the plant leaves are sprayed with a zoospore suspension. The plants are then incubated for 5 days in the irrigated chamber at a temperature in the range of 18 to 20 ° C and saturated air humidity. After the indicated time has elapsed, typical spots have formed on the Xyst x, the number and size of which serve as a measure of the activity investigated biologically active substances.
    Curative action. Complete or almost complete inhibition of the lesion by fungi (0-5% lesion) is achieved with the use of compounds 1, 4, 8, 9, 10, 13, 17, 18, 19, 22, 23 and 41. The following compounds have the indicated effect even at a concentration of 0 , 02%: 1, 4, 8, 19, 20 and 41.
    Warning - system action.
    Complete or almost complete inhibition of the lesion by a fungus (0-5% lesion) was achieved using compounds 1-5, 7, 9, 11, 13-21, 23, 24-27, 29, 30, 33, 34, 37, 39, 40 The following compounds showed such activity even at a concentration of 0.002%: 1, 5, 12, 13, 15, 16, 18, 19, 23, 33, 34, 37.
    The defeat of untreated but infected control plants serves in each case as a standard (100% of fungal damage).
    Example 3. Action against Plasmopara viticola.
    Residual preventive action.
    Viyograda seedlings are grown in the greenhouse. At the 10 leaf stage, plants are sprayed with liquid (0.06% of the biologically active substance). After drying the applied liquid, the underside of padrenium leaves infect evenly with a spore suspension of the fungus. Immediately after this, the plants are kept for 8 days in a humid chamber. After the indicated time had elapsed, control symptoms appeared on the control plants. The amount and size of the affected areas on the treated plants served as the scale for evaluating the activity of the substances under study.
    When using compounds 4, 13, 16, 20, 28, 39, fungal infection was 0-5%.
    Example 4. Action against Pvthium debaryanum.
     Action after tillage.
    The fungus was cultivated on sterile oat grains and added to a mixture of earth and sand. The soil infected in this way was placed in flower pots and the seeds of sakarn beets were sown. Immediately after sowing, the ground was sprayed with an aqueous suspension of the test drug. (200 million of biologically active substances / based on the volume of soil).
    After that, the pots were kept in a greenhouse for 2–3 weeks with an IreMnepaTyipe of 20–24 ° C. At the same time, the earth was maintained evenly in the idle state by weak spraying with water.
    Action after treatment for dressing.
    The fungus was cultivated on stale and oat kernels of oats and added to a mixture of earth and sand. The ground contaminated by the above method was placed in pots, after which the seeds of sugar beet were sown, which were treated with the test preparation, prepared in the form of powdered treater (100 million biologically active substance, calculated on the weight of seeds). The trapped pots were kept for 2- 3 weeks in the greenhouse at a temperature of 20-24 0. At the same time, the earth was kept in a uniformly moist state by lightly spraying with water.
    In evaluating both experiments, the germination of sugar beet plants as well as the number of healthy and diseased plants was determined.
    More than 85% of plants appeared when they were treated with one of the compounds 1, 4, 6-10, 14, 15, 17, 18, 21, 22, 24, 26, 28, 34, 35, 38, 40, 41. More than 90 % of the plants sprung when processing one of the compounds 12, 13, 16, 20, 37, 39.
    Example 5. Action against Erysiphe graminis.
    Residual protective action.
    Barley plants about 8 cm high were sprayed with a liquid prepared from a wetting powder based on a biologically active substance (0.06% of an actin). After 48 hours, the treated plants were dusted with conidia of the fungus. Infected barley plants were kept in a greenhouse at a temperature of approximately. Fungus lesions were assessed after 10 days.
