摘要： A method of thinning lateral flowers of apples, comprising applying of flower thinning effective amount of a pyrazole compound represented by general formula (I) ##STR1## wherein R.sub.1 represents an alkyl group having 1 to 4 carbon atoms; andR.sub.2 and R.sub.3, which are the same or different, each represent a hydrogen atom or an alkyl group having 1 to 4 carbon atoms,to flowers of apples. A compound in which R.sub.1 and R.sub.2 are each a methyl group, and R.sub.3 is a hydrogen atom is preferred. The pyrazole compounds are applied at a flowering stage of apples, preferably in a period from immediately after full bloom to terminal flowers of apples to 2 days thereafter, typically in a proportion of from about 5 mg to about 75 g per tree at a coverage in a range of from about 20 mg/10a to about 2,000 g/10a.
