FIELD: organic chemistry. SUBSTANCE: composition has derivatives of pyrimidine of the formula (I) where R1 - lower alkyl, haloid-C1-C4-alkyl, C1-C4-alkoxy-C1-C4-alkyl, cyano-C1-C4-alkyl, C1-C4-alkoxycarbonylalkyl, benzyl; R2 - C1-C6-alkyl, cyclo-C3-C6-alkyl, haloid-C1-C4-alkyl, C1-C4-alkoxy-C1-C4-alkyl, cyano-C1-C4-alkyl, C1-C4-alkoxycarbonyl-C1-C4-alkyl; or R1 and R2 together form C4-C6-alkylene which can be substituted with methine groups, C4-C5-alkylene containing oxygen in chain; Y1 - H, lower alkyl, C1-C4-alkoxy or halogen; Y2 - lower alkyl; Y3-H C1-C4-alkyl, C1-C4-alkoxy or halogen; CY4-alkoxy, haloid; X - haloid or sulfur; Z - nitrogen or Y4 H, halogen, C1-C4-alkyl, C1-C4-alkoxy, haloid-C1-C4-alkyl, phenyl, C1-C4-alkoxycarbonyl or nitro-group; R3 - lower alkyl, C1-C4-alkoxy; 
- lower alkyl, halogen. Composition is used at concentration 2-50 wt.-%, additions - the rest. Weed plants were treated with proposed composition at the dose 0.005-10 g/are. Synthesized compounds were used in agriculture. EFFECT: improved method of synthesis, increased effectiveness of herbicide composition. 3 cl, 17 tbl
