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.
