    This invention relates to chemical agents for controlling undesirable vegetation in crops of cultivated crops. A method of combating undesirable vegetation is already known, in which the treatment of crops is carried out with derivatives of 2,6-dinitroaniline of the general formula </ BR> where Ri is alk-yl. C2, alkenyl, alkynyl or aryl; hydrogen, alkyl, alkenyl, or alkynyl or R and R hydrocarbon with 2-6 carbon atoms, with which the nitrogen atom forms a heterocyclic ring R, is alkyl C; Y is oxygen or sulfur; Z is alkyl C.,; - C, halogen or trifluoroethyl. However, the known weedy vegetation method is not very effective in bites with acti vi not at a planting site where, if the gerd is cultivated, the method of controlling the desired vegetation, which is pre-emergent harvesting, is derived , 6-nitroaniline of the general formula: hydrogen, alkyl with 1-6 carbon atoms, alkenyl or alkyline with 2-6 carbon atoms; . alkyl with a carbon number of 2-7, which may be straight or branched chain, or cycloalkyl, alkenyl or alkynyl with a carbon number of 2-6, alkyl with a carbon number of 1-4, which may be replaced with gyrshogen or
    alkoxygroup with the number of carbon atoms 1-4} Rj together can form
    piperidine, pyrrolidine or morpholium group, moreover, when Y and Z mean meth, and hydrogen, or ethyl, then Rj cannot be ethyl;
    V - voivorod, yykyl with a number of atr
    1-4 moss carbon, 2-4 alkenyl with carbon atoms, CP group, -CN or SOjNR R; . :
    Z is an alkyl with a carbon number of 1-4, alKoyl with a carbon number of 2-4. Or alkyl with a carbon number of 1-4, which may be substituted by halogen, an alkoxy group with a carbon number or 1-.4 or a group of NR, and R each separately means hydrogen, or alkyl with 1-4 carbon atoms.
    The preferred compound used in this process is 3,4-dimethyl-2,6-dinitro-H-3-pentylaniline. .
    Example. The seeds of sugar beet, cotton, soy, Ezovniki elezeni, impomei, oats, bukharnika, are sown in the soil, which is treated with the test compounds listed in Tables 1-12. After three to four weeks, the herbicidal activity is recorded as a percentage of control or in points. Rating scale: O - no damage; 3 - individual spots of burns, 5 - separate plants of the sinking and severe burns, 9 - complete destruction of plants and delayed growth of plants. Test plants; BUT - . Elevzina, E - Bukharnik, B - Osote, G - Valerian, D - Beans, E - Oats, F - Uzhovnik, 3 - Syt, I - Impome, K - Cotton, L - Sugar beet, M - with. The test results are presented in table.1-4.
