Abstract
A herbicidal composition for foliar treatment is described, which contains as active ingredients, (a) a compound of general formula [1] wherein R is alkyl, cycloalkyl, alkenyl, dimethylamino, or diethylamino; and (b) a compound selected from the group consisting of imazethapyr or a salt thereof, imazaquin or a salt thereof, imazamox or a salt thereof, acifluorfen-sodium, lactofen, fomesafen, clethodim, sethoxydim, fenoxaprop-P-ethyl, fluazifop-P-butyl, and quizalofop-P-ethyl. The herbicidal composition is useful for effective control of a wide variety of weeds in upland fields, particularly in soybean fields. Also described are a weeding method by foliar treatment of weeds with the above herbicidal composition; and use as a herbicide for foliar treatment, of a mixture of the above active ingredients. ##STR1##
