HERBICIDE COMPOSITIONS FOR UPLAND FARMING AND CONTROL METHOD

摘要

The present invention relates to a herbicide composition comprising, as active ingredients, at least one compound selected from the thienopyrimidine derivatives represented by the formula (I):wherein R¹ represents a fluoroalkyl group having 1 or 2 carbon atoms, a fluoroalkoxy group having 1 or 2 carbon atoms or a fluoroalkylthio group having 1 or 2 carbon atoms, R² represents a linear or branched alkyl group having 1 to 4 carbon atoms or a linear or branched fluoroalkyl group having 1 to 4 carbon atoms, and R³ and R⁴ each independently represent a hydrogen atom or a linear or branched alkyl group having 1 to 3 carbon atoms; and one or two or more kinds of 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, fluroxypyr or a derivative thereof, clopyralid or a derivative thereof, flufenacet, flurtamone and pinoxaden, and a method for using the same.
