AbstractMembers of series of 4‐(cyclobutylalkyl, cyclohexylalkyl and benzylalkyl)‐2,6‐dinitrophenols were tested in a glasshouse against apple powdery mildew caused byPodosphaera leucotricha.Three series involving a cyclohexyl substituent separated from the phenolic nucleus by one, two or three methylene groups were of the same order of activity, but replacement of this substituent by a phenyl group in one case, resulted in a marked decrease in activity. Of a number of esters tested, none was significantly more active than the corresponding p
