6-aryl-pyrdine-thiosemicarbazones of the formula
where
R1 is hydrogen or methyl;
R2 is (C1-C4)alkyl;
R3 is (C1-C4)alkyl; or
R2 and R3 may be taken together with the nitrogen atom
to which they are attached to form a 3 to 6 membered heterocycle having 2 to 5 nuclear carbon atoms;
X is halo, nitro, (C1-C4)alkyl, (C1-C4)haloalkyl or (C1-C4)alkoxy;
Y is hydrogen, halo, N02, (C1-C4)alkyl or (C1-C4) alkoxy; or when two adjacent positions on the phenyl ring are substituted with alkoxy groups, these alkoxy groups may be joined to form, together with the carbon atoms to which they are attached, a dioxolano or dioxano heterocyclic ring;
n is 0, 1 or 2;
and agronomically acceptable salts thereof are useful as insecticides especially against insects from the order Lepidoptera.
