This invention relates to pteridine and 8-deazapteridine compounds and compositions containing the same which are useful for controlling insects in agricultural crops. These pteridines may be represented by the following structure: ##STR1## wherein R and R.sup.1 are independently selected from amino, lower alkylamino, di(lower alkyl)amino (e.g., --N(CH.sub.3).sub.2), or di(lower alkyl)aminomethyleneamino (e.g., --N.dbd.CHN(CH.sub.3).sub.2);

Insecticidal pteridines and 8-deazapteridines

An insecticidal composition comprising, in admixture with an agriculturally acceptable carrier, an insecticidally effective amount of a compound of the formula: ##STR1## wherein R, R.sup.1, R.sup.2, R.sup.3, R.sup.7, R.sup.8, m, n, and p are as defined herein, and agriculturally acceptable salts thereof, and methods of using the same.

Insecticidal 5-substituted-2,4-diaminopyrimidine derivatives

An insecticidal composition comprising, in admixture with an agriculturally acceptable carrier, an insecticidally effective amount of a 2,4-diaminoquinazoline compound of the formula: ##STR1## wherein R.sup.1, R.sup.2, R.sup.6, R.sup.7, W, X, Y, and Z are as defined herein; methods of using the same; novel 2,4-diaminoquinazolines per se; and intermediates in the preparation thereof.

Insecticidal substituted-2,4-diaminoquinazolines

This invention relates to pteridine and 8-deazapteridine compounds which are useful for controlling insects in agricultural crops. These pteridines may be represented by the following structure: ##STR1## wherein R and R.sup.1 are amino;

Insecticidal pterdines and 8-deazapteridines

Insects, and particularly the larvae of Lepidoptera and Coleoptera, are controlled by application of 4,6-diamino-1,2-dihydro-dihydro-1,3,5-trazine derivatives, and agriculturally acceptable salts thereof, having the following structure; ##STR1## when they are admixed with a compatible agricultural vehicle; additionally, certain related novel heterocyclyl, phenyl, and naphthyl triazines and their substituted counterparts are also taught.
