Abstract: Phosphorus derivatives of 5-pyrimidinols which possess insecticidal properties and especially both systemic and foliar activity for plants against insect pests.

Abstract: Novel 2-alkyl-5-halopyrimidines, e.g., 5-chloro-2-(1,1-dimethylethyl)pyrimidine, which are useful as intermediates in the preparation of, e.g., O,O-diethyl O-(2-(1,1-dimethylethyl)-5-pyrimidinyl) phosphorothioate which is useful as an insecticide against corn rootworm and cutworm.

Abstract: Compounds of the formulas: ##STR1## wherein R is alkylcycloalkyl having 4 to 6 carbon atoms; R' is hydrogen, alkyl or alkylthio of 1 to 3 carbons; R" is alkyl having 1 to 4 carbon atoms; X is oxygen or sulfur; and R'" is alkyl of 1 to 2 carbons, alkoxy, alkylthio or monoalkylamino, each with 1 to 4 carbon atoms, or phenyl. The novel 1-alkylcycloalkyl pyrimidinols are used in preparing the phosphate compounds which are highly useful corn rootworm control agents and are particularly valuable when applied to the soil, but are also useful applied to foliage of corn. Especially good control is obtained of corn rootworm. The compounds are conveniently applied in the form of a composition containing a pesticidal carrier such as an inert solvent or a finely divided inert solid in which case the composition is preferably granulated. An effective application rate is in the range of about 0.1 to about 5 pounds per acre when soil incorporated, and about 0.5 to about 2000 ppm for foliar applications.

Abstract: O,O-Diethyl O-(4-(t-butylsulfonyl)-m-tolyl) phosphorothioate is an active insecticide for the kill and control of the copper bottle fly and the southern cattle tick.

Abstract: O,O-diethyl O-[-4-(t-butylsulfinyl)phenyl]phosphorothioate is an active insecticide for the kill and control of cucumber beetle larvae.

Abstract: Compounds of the formula: ##STR1## wherein R is hydrogen; alkyl of 1 to 8 carbons; alkylthiomethyl, alkylsulfinylmethyl or alkylsulfonylmethyl wherein alkyl contains 1 to 4 carbons; phenyl; phenylthio; alkylthio, alkylsulfinyl or alkylsulfonyl wherein alkyl contains 1 to 4 carbons; or alkylthio-ethylthio wherein alkyl contains 1 to 2 carbons;R' is hydrogen, methyl or alkylthio of 1 to 2 carbons;R" is hydrogen or methyl;X is oxygen or sulfur;R'" is alkyl of 1 to 2 carbons; andR"" is --OR'" or --S-alkyl of 1 to 4 carbons,are highly useful insecticides which are paricularly valuable when applied to the soil, but are also useful applied to foliage of crops or trees. Especially good control is obtained of corn rootworm, codling moth, thrips, leafhoppers, and nematodes. The compounds are conveniently applied in the form of a composition containing a pesticidal carrier such as an inert solvent or a finely divided inert solid in which case the composition is preferably granulated.

Abstract: O,O-Dialkyl O-?4-(tert-alkylsulfinyl)-2-chlorophenyl! phosphorothioate and the corresponding sulfonyl compounds are active insecticides for the kill and control of codling moth larvae.

Abstract: The present invention is directed to N-((alkylamino)carbonyl)-N-(((alkylamino)carbonyl)oxy)acylamides and their use in inhibiting the growth of HeLa cells, P.sub.388 leukemia or MX-1 carcinomas in mammals.

Abstract: 0,0-Dimethyl 0-[(4-tert-butylsulfinyl)-2-methoxyphenyl]phosphorothioate and 0,0-dimethyl 0-[(p-tert-amylsulfinyl)phenyl]phosphorothioate are active in the kill and control of black cutworms.

Abstract: The compound N-(4-chloro-2-methylphenyl)-N'-hydroxy methanimidamide is prepared and used as an insecticide.
