SUMMARY Six 4‐(1‐phenylalkyl)‐, eight 4‐(1‐cyclohexylalkyl)‐, seven 4‐(1‐cyclo‐pentylalkyl)‐ and seven 4‐(1‐cyclobutylalkyl)‐2,6‐dinitrophenols, together with some derivatives, were tested against the powdery mildews of apple (caused by Podosphaera leucotricha ) and blackcurrant (caused by Sphaerotheca mors‐uvae ) in the greenhouse and in field trials, against rose mildew (caused by S. pannosa ) in the field, and against Venturia inaequalis in spore germination tests. Highest activity in the greenhouse was shown by members of the cyclobutyl series with 4–6 carbon atoms in the alkyl group. No phytotoxicity on healthy foliage occurred with any compound in these series.
