Abstract

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 ml. The wood-chip colonization by P. tremulae was not affected by the six most active compounds at 1 ml, however, at 10 and 100 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 ml.
