The invention provides methods comprising applying to a crop of soybean plants, the locus thereof, or propagation material thereof, a compound of formula (I) wherein —B1—B2—B3— is —C═N—O—, —C═N—CH2— or —N—CH2—CH2—； Y1, Y2 and Y3 are independently CH or nitrogen； wherein no more than two of Y1, Y2 and Y3 are nitrogen and wherein Y2 and Y3 are not both nitrogen； R9 is C1-C4alkyl, C1-C4haloalkyl, C1-C4alkyl-O—CH2—, C1-C4haloalkyl-O—CH2—, C3-C6cycloalkyl, C3-C6cycloalkyl-CH2—, C1-C4alkyl-S—CH2—, C1-C4alkyl-S(O)—CH2—, or C1-C4alkyl-S(O2)—CH2—； X2 is C—X6 or nitrogen； X1, X3 and X6 are independently hydrogen, halogen or trihalomethyl, wherein at least two of X1, X3 and X6 are not hydrogen； X4 is trifluoromethyl, difluoromethyl or chlorodifluoromethyl. Preferably the methods are for control of stinkbugs, in particular from the genus Euschistus and in particular the species Euschistus heros.
