    The invention relates to chemical plant protection products, specifically, to a fungicidal composition based on pyrrole derivatives.
    The known fungicidal composition, which, in addition to the active substance based on 3-phenylpyrol derivatives, contains the auxiliary components Cl.
     However, the known phenylpyrroles have insufficient activity, they are unstable under the action of light, and, moreover, their residual effect is small.
    The purpose of the invention is to enhance the fungicidal activity.
    This goal is achieved by using a composition containing an active substance of the formula
    Example 1. Bean seedlings placed in bowls are grown for 3 weeks and then sprayed with a solution prepared from a wetting powder. After the treated leaves are air-dried, they are inoculated with Botrytis cinerea's mycelium and kept at 20 ° C in the VLAN. The effect of the control is determined 4 days after inoculation.
    The results are shown in Table 2. No phototoxicity was observed.

    In this way, the compounds shown in Table 1 are obtained.

    Example 2. Control of gray rot of beans (residual effect).
    Potted bean seedlings are usually: about 3 weeks old (PhaseoKus vu6garis L) about one week old, they are sprayed with a spice solution at a concentration of 200 ppm of active ingredient, and then kept in a greenhouse. Fox1: b is cut off and inoculated with Botrytis cinerea mycelium 7 days after spraying and kept in a humid chamber at. The effect of the control is determined 4 days after inoculation.
    The data obtained are given in table.3. Phyto-toxicity is not observed. 31083895 Table. 1100 2100 3.93 590 5 10 4 Continuation of the table 3 1 2 b89 787 3-Chloro-4 (2-nitro-Zchlorophenyl) -pyrrole (comparative compound) O With this composition, ofipaaoMf, offers a high fungicidal activity.
