<p>Novel 3-amino-2,4-dialkylpyridine derivatives <IMAGE> (I) in which R1 and R2 are each independently C1-C6alkyl, R3 is C1-C12alkyl, C3-C6cycloalkyl, C1-C4alkyl substituted by C3-C6cycloalkyl, or C3-C6 cycloalkyl substituted by C1-C4alkyl, R4 is hydrogen, halogen, C1-C6alkyl, phenoxy, or phenoxy that is mono- or di-substituted by halogen, C1-C4alkyl, C1-C4 alkoxy, C1-C4alkylthio, C1-C4alkylamino, di-C1-C4alkylamino, C1-C4alkylcarbonylamino, C1-C4alkylcarbonyl, benzoyl, nitro, cyano, C1-C4alkoxycarbonyl, C1-C4haloalkyl or by C1-C4haloalkoxy, and Z is a bridge member -NH-CS-NH-, -N=C(SR5)-NH- or -N=C=N- wherein R5 is C1-C6alkyl or C3-C5alkenyl, can be used as pesticides. Preferably, insects and arachnids can be controlled.</p> |
