FIELD: agriculture. SUBSTANCE: present invention describes optically active 2-imidazolin-5-one derivatives of general formula 1: wherein W is oxygen atom, M is oxygen or sulfur atom; R 1 and R 2 are different and are alkyl or phenyl substituted by 1-3 groups selected from R 6 ;; R 3 is C 1-2 алкил alkyl; R 4 is H or phenyl optionally substituted by 1-3 groups selected from R 6 ; R 5 is H except that when R 4 is H or phenyl optionally substituted from R 6 ; R 6 is halogen or phenoxy optionally substituted by halogen atom. Said compounds are prepared by reacting compound of formula II: , wherein W is oxygen atom, with compound of formula R 3 X wherein X is chlorine, bromine or iodine atom or sulfate group or alkylsulphonyloxy- or arylsulfonyloxy group. Compositions based on compounds of formula I are useful as fungicidal agents. EFFECT: improved properties of the fungicidal composition. 11 cl, 10 ex, 11 tbl |
