    摘要: A wood preservative composition for control of wood decay by fungi, which comprises 2H-benzopyran-2-spiro-3'-phthalide or its derivatives such as 6-methyl-2H-benzopyran-2-spiro-3'-phthalide or benzo[f]-2H-benzopyran-2-spiro-3'-phthalide as an active ingredient. The active ingredient has extremely low mammalian toxicity, and exhibits an excellent wood-decay controlling effect.
