Insecticidal triazines and pyrimidines

A method of using a compound of Formula (I),

• wherein:
• Y is CR1;
• R1 is —H, Halo or —C1-C4 alkyl;
• Z is -aryl, —C1-C8 alkylaryl, —C3-C8 cycloalkyl, —C1-C6 alkylC6cycloalkyl, heterocyclic, —C1-C8 alkylheterocyclic,
• X, is —H, —C1-C8 alkyl, -aryl, —C1-C8 alkylaryl, —C3-C8 cycloalkyl, —C1-C8 alkylC3-C8 cycloalkyl, heterocyclic, —C1-C8 alkylheterocyclic, —NRiRj or —C1-C8 alkylNRiRj;
• R2 and R3 are independently —H or —C1-C8 alkyl, -aryl, —C1-C8 alkylaryl, —C3-C8 cycloalkyl, —C1-C8 alkylC3-C8 cycloalkyl, heterocyclic, —C1-C8 alkylheterocyclic, and —C1-C8 alkylNRiRj, but R2 and R3 are not both H;
• Ri and Rj are independently —H, or —C1-C8 alkyl;
• wherein heterocyclic is a 5-10 member cyclic or bicyclic aromatic or saturated —C1-C8 cycloaliphatic ring moiety containing 1, 2, or 3 heteroatoms selected from N, O, or S;
• wherein aryl, —C3-C8 cycloalkyl and heterocyclic are optionally independently substituted with one to five substituents independently selected from -halo, —CN, —OH, —OCH2CH═CHCl, —C1-C6 alkyl, —O—C1-C6 alkyl, or —S—C1-C6 alkyl;
• and at each occurrence alkyl, is optionally substituted with 1-5 halo, —CN, or —OH in order to control and inhibit:
• insects, mites and nematodes, comprising applying an insect-inhibiting amount of a compound of Formula I to the locus, area to be protected or directly on the insects, mites and nematodes.
