月见草病的病原菌月见草拟青霉产生的主要植物毒素已被鉴定为氧孢子酮，这是一种以前未见过的植物毒素。吡喃酮是一种新发现的新毒素，其化学成分为6-(1‘-甲基丙基-1’-烯基)-4-甲氧基-2-吡喃酮。赤霉菌产生的赤霉素增效剂梨糖素和羟基梨糖素也是由该真菌产生的，只有微弱的植物毒性。
The major phytotoxin produced by Pestalotiopsis oenotherae, a pathogen of evening primrose, has been identified as oxysporone, a compound not previously known as a phytotoxin. Pestalopyrone, a minor new toxin, has been shown to be 6-(1'-methylprop-1'-enyl)-4-methoxy-2-pyrone. The gibberellin synergists pestalotin and hydroxypestalotin, also produced by this fungus, are only weakly phytotoxic.
