The present invention relates to the use of a glyphosate herbicide for controlling unwanted vegetation in Beta vulgaris growing areas in which the Beta vulgaris plants comprise an endogenous allele encoding an epsp synthase having at position 179 an amino acid different from proline.

The present invention provides a compound having an excellent efficacy for controlling weeds. A dihydropyrone compound of formula (I): wherein m is 1, 2 or 3; n is an integer of any one of 1 to 5; X represents O, S, S(O) or S(O).sub.2; R.sup.1 represents a hydrogen atom or a methyl group; R.sup.2 and R.sup.3 represents a hydrogen atom, an C.sub.1-6 alkyl group and the like; when X represents S, S(O) or S(O).sub.2, R.sup.4 represents an C.sub.1-6 alkyl group, a C.sub.1-6 haloalkyl group, an C.sub.6-10 aryl group or a five- to six-membered heteroaryl group, and X represents O, S, S(O) or S(O).sub.2, R.sup.4 represents an C.sub.6-10 aryl group or a five- to six-membered heteroaryl group; G represents a hydrogen atom and the like; Z represents a halogen atom, a cyano group, a nitro group, a phenyl group, an C.sub.1-6 alkyl group and the like; is useful as an active ingredient for herbicides. ##STR00001##

The present disclosure provides a method for treating rice. The method comprises the steps of: providing a domestic rice crop plant and at least one ACCase-inhibiting aryloxyphenoxypropanoate herbicide selected from the group consisting of quizalofop or an ester thereof, haloxyfop, fluazifop or an ester thereof, clodinafop, clodinafop-propargyl, diclofop, and diclofop-methyl; applying an effective amount (measured in g AI/Ha) of the at least one aryloxyphenoxypropanoate herbicide to the domestic rice crop plant, post-emergence; thereby creating a treated rice plant; and growing the resulting treated rice plant.
