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.
该化合物的分子式为:##STR1##其中R是具有4到6个碳原子的烷基环烷基;R'是氢,1到3个碳的烷基或烷基硫;R"是具有1到4个碳原子的烷基;X是氧或硫;R'"是1到2个碳的烷基,烷氧基,烷基硫或单烷基氨基,每个原子有1到4个碳,或苯环。新型的1-烷基环烷基嘧啶醇用于制备磷酸盐化合物,这些化合物是高度有效的玉米根虫控制剂,特别是在施用于土壤时非常有价值,但也适用于施用于玉米叶面。特别是对于玉米根虫的控制效果非常好。这些化合物通常以杀虫剂载体的形式施用,例如惰性溶剂或细粉惰性固体,此时,该组合物最好是颗粒状的。有效的施用速率在土壤中为每英亩约0.1到约5磅,叶面施用为约0.5到约2000 ppm。
