Abstract: Novel insecticides of the formula ##STR1## in which n is 0 or 1,X is S, O, ##STR2## Y is N or ##STR3## Z is a 5- or 6-membered nitrogen-containing heterocyclic ring, and R to R.sup.9 variously represent hydrogen or specified organic radicals.
Abstract: Articles of manufacture are disclosed for the controlled delivery of pest controlling substances. Methods for producing such articles and utilizing them in pest control programs are also described. Laminated articles are provided which comprise one or more layers containing active pest control and pest attractant substances and which allow the controlled release of the pest controlling substance from within the laminate to the surface of the laminate so as to maximize efficiency against target species in the surrounding environment. The laminated structure also permits prolonged, controlled release of pest controlling substances and properly timed combinations of such substances that might otherwise be prematurely dissipated, decomposed or inefficiently applied. Various combinations of polymeric materials and active agents and a number of different laminated structures are utilized to optimize efficient use of the pest controlling substance against a variety of target species.
Abstract: Novel phosphoaziridines of the formula: ##STR1## wherein Z is oxygen or sulfur, R.sub.1 is independently at each occurrence H or --CH.sub.3, R.sub.2 is independently at each occurrence --CH.sub.3 or nitrophenyl R.sub.5 ; R.sub.3 is --NHR.sub.4, --OR.sub.4, --SR.sub.4 or ##STR2## where R.sub.4 is a radical containing up to 30 atoms including at least one amine, ester, ether, alkyl, substituted alkyl, hydrogen, phenyl, substituted phenyl, carbamate, heterocyclic ring or R.sub.5 group; provided that, when R.sub.4 contains and R.sub.5 group, R.sub.4 has an alkyl group between the phosphorous and the R.sub.5 group; and R.sub.5 is a radical containing and electron affinic group comprising a quinone, or a heterocyclic or phenyl ring directly connected to a radical selected from the group consisting of nitro, nitroso, sulfinyl, sulfoxine, and N-oxide; provided that the compound contains at least one R.sub.5 radical and provided that when R.sub.1 is H, the R.sub.2 group on the same ring is R.sub.
