FIELD: organic chemistry, herbicides. SUBSTANCE: invention describes the novel derivatives of pyrazole of the general formula (I) where R1 is C1-C6-alkyl; R2, X1, X2 mean independently C1-C4-alkyl; R3 is hydrogen atom or C1-C4-alkyl; m = 0 or 1; R4 is C1-C4-alkyl or the group of the formula where Y is halogen atom, C1-C4-alkoxy-group or C1-C4-alkyl; n = 0-3; R5 is A-group, -S(O)2-, -C-, -CH2-C- or (-C-) where R5 or R6 is hydrogen atom and P = 1-4 and compounds of the general formula (XI) where R11, R12, R13, R14, R15, R16, R17, X3, A2, B, n and P have values given in p. 11 of the invention claim. These compounds are used as herbicides. Derivatives of pyrazole of the general formula (I) show selectivity with respect to rice-paddy and maize and in low doses abolish the broad spectrum of weeds in flooded and dry valley fields. Derivatives of pyrazole of the general formula (I) have no phytotoxic effect of rice-paddy plants and in low doses they abolish the broad spectrum of weeds in dry valley and flooded rice fields being especially barnyard-millet and long goutweed. EFFECT: improved method of synthesis, high effectiveness against weeds. 21 cl, 32 tbl, 5 dwg, 65 ex
