Summary Phellinus tremulae is the most important decay fungus on Populus tremuloides . In forest industries using aspen wood chips, two blue‐stain fungi Ophiostoma crassivaginatum and Ophiostoma piliferum cause considerable reduction in the value of the end product. Thirty‐eight homologues and analogues of 4‐phenyl‐3‐butenoic acid were studied against P. tremulae, O. crassivaginatum , and O. piliferum . Varied inhibition of the in vitro growth of these fungi was observed at 1–1000 μg/ml. The wood‐chip colonization by P. tremulae was not affected by the six most active compounds at 1 μg/ml, however, at 10 and 100 μg/ml the growth of P. tremulae on wood chips was totally arrested. 4‐Phenyl‐3‐butenoic acid and 4‐phenyl‐3‐butynoic acid prevented blue‐stain development on wood chips at 1 μg/ml.
