Abstract: 3,4,5,6-Terahydrophthalimides with herbicidal activity are provided, which compounds non-selectively control weeds in a fruit garden, and selectively control Gramineae and large-leaf weeds by treatment of a small amount of soil with the compounds without damage of useful crops. The 3,4,5,6-terahydrophthalimides represented by formula (1) are provided, wherein n is 0 or 1; X is Cl or CN; and R is H, halogen, CN, methyl, ethyl, COOH, CO2Me, CO2Et, methoxy, ethoxy, OCH2CO2Et, OCH(CH2)CO2Et, SCH3 or SO2CH3. An herbicidal composition comprises the 3,4,5,6-terahydrophthalimides represented by formula (1) or its salts. The 3,4,5,6-terahydrophthalimides represented by formula (1) are prepared by reacting a compound of formula (2) with a compound of formula (3) according to the reaction formula (1).
