PROBLEM TO BE SOLVED: To obtain a herbicide that rapidly develops herbicidal effect, has a wide weeding spectrum and selectively controls a wide range of weeds especially in the field of wheat or barley cultivation. SOLUTION: The herbicide composition comprises a thienopyrimidine derivative represented by general formula (I) (R<SP>1</SP>is a 1-2C fluorine-containing alkyl, a 1-2C fluorine-containing alkoxy or a 1-2C fluorine-containing alkylthio; R<SP>2</SP>is a 1-4C alkyl or a 1-4C fluorine-containing alkyl; R<SP>3</SP>and R<SP>4</SP>are each H or a 1-3C alkyl) and one or more herbicides selected from a urea-based herbicide, a dinitroaniline-based herbicide, a phenoxypropionic acid-based herbicide, a cyclohexanedione-based herbicide, an imidazolinone-based herbicide, a sulfonylurea-based herbicide, a carbamate-based herbicide, a triazolinone-based herbicide, a triazolopyrimidine-based herbicide, etc., as active ingredients.
