SUBSTANCE: invention describes novel 2-amino-4-bicycloamino-1,3,5-triazines of the general formula (I): wherein R¹ and R² mean independently hydrogen atom, amino-group, (C₁-C₆)-alkyl, (C₁-C₄)-alkanoyl, phenylalkyl c 1-6 carbon atoms in alkyl moiety and possibly substituted with halogen atom; or R¹ and R² in common with nitrogen atom to which they are bound form morpholino-group; R³ means hydrogen atom, (C₁-C₆)-alkyl possibly substituted with halogen atom, hydroxy-, amino-, di-(C₁-C₄-alkyl)amino-, cyano-group, phenyl, (C₁-C₄)-alkoxy-, carboxy-group or (C₃-C₉)-cycloalkyl that can be substituted with halogen atom, phenyl possibly substituted with halogen atom, (C₁-C₆)-alkyl, hydroxy-group or phenyl, amino-, di-(C₁-C₄-alkyl)amino-, (C₁-C₆)-alkoxy-, (C₁-C₆)-alkylthio-group, or (C₂-C₆)-alkenyl; R⁴ and R⁵ mean independently hydrogen atom, (C₁-C₄)-alkyl or (C₁-C₄)-alkanoyl; R⁶ means independently (C₁-C₆)-alkyl, (C₁-C₆)-alkoxy-group or halogen atom; Y¹ means a direct bond or -CH₂-; Y² means group -CR^aR^b wherein R^a and R^b mean independently hydrogen atom or (C₁-C₆)-alkyl; Y³ means a direct bond, Y²-independent group -CR^aR^b wherein R^a and R^b mean independently hydrogen atom or (C₁-C₆)-alkyl, or bivalent group of the formula -O-, -S-; m means 1, 2 or 3; n means 0, 1, 2, 3 or 4, or their salts. Novel compounds possess herbicide activity with the effectiveness 60-100%, for example, in rice plantings and wherein damages of cultivate plants do not exceed 10%.

EFFECT: valuable herbicide properties of compounds.
