1. A method of treating a plant or a growing media for a nematode, said method comprising:
contacting a plant or a growing media with a nematicide compound of formula (IIa) having the following structure:

OG Complex Work Unit Chemistry
 where
R4 is selected from the group consisting of:
phenyl;
phenyl substituted only at the para position with a halogen, CF3, NO2, S(C1-C3 alkyl), dimethylamine, C1-C3 alkyl, sulfonyl, C1-C3 alkoxy, morpholinyl, or tetrazolyl;
phenyl substituted only at the meta position with a halogen;
phenyl substituted only at the para and meta positions with substituents independently selected from halogen and C1-C3 alkoxy;
phenyl substituted only at the para and ortho positions with a halogen other than chlorine;
C1-C3 alkyl substituted pyrazolyl;
2,3-dihydrobenzofuranyl;
pyridinyl;
thiophenyl; and
benzodioxolyl;
R5 is H; and
R6 is H
to treat the plant or growing media for a nematode, wherein said treating is carried out to kill a soybean cyst nematode (SCN) or SCN egg or to inhibit SCN growth or reproduction.
