| abstract |
There is provided an insecticidal composition comprising, in admixture with an agriculturally acceptable carrier, an insecticidally effective amount of a diaminoquinazoline compound of formula (I) wherein R1 is hydrogen or lower alkyl; R2 is hydrogen, lower alkyl, lower alkylcarbonyl, or lower alkoxycarbonyl; or R?1 and R2¿, taken together, form the group -R5-O-R5, wherein R5 is lower alkylene; R6 is hydrogen; R7 is hydrogen, lower alkylcarbonyl, or lower alkoxycarbonyl; W, Y, and Z are independently hydrogen, halogen, lower alkyl, lower alkoxy, lower haloalkyl, lower haloalkoxy, thienyl or substituted thienyl, aroyl or substituted aroyl, cyano, nitro, amino, lower dialkylamino, aryl or substituted aryl, arylalkyl, arylalkenyl, arylalkynyl, arylthio, arylsulfinyl, arylsulfonyl, arylaminoalkyl, arylalkylamino, arylalkylimino, (aryl)(halo)alkenyl or substituted (aryl)(halo)alkenyl, (aryl)(alkyl)aminoalkyl, arylalkycarbonylamino, arylalkylthio, or arylthioalkyl; and X is one of five types of moieties defined in the description; novel substituted diaminoquinazoline compounds per se are also identified. |
