<p>Compounds of the formulas: <CHEM> wherein R is alkylcycloalkyl or cycloalkylalkyl having 4 to 6 carbon atoms; R min is hydrogen, alkyl or alkylthio of 1 to 3 carbons; R sec 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 2-cycloalkylalkyl or alkylcycloalkyl pyrimidinols are used in preparing the phosphate compounds which are highly useful insecticides and are particularly 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, black cutworm, European corn borer, 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. An effective application rate is in the range of 0.1 to 5 pounds per acre (0.112 to 5.6 kg/hectare) when soil incorporated, and 0.5 to 2000 ppm for foliar applications.</p> |
