A variety of organic materials susceptible to fungal attack (especially wood and wood-based materials) can be protected from such attack and fungi growing on such materials can be eradicated by treating them, e.g. by applying to the surfaces or impregnating, with one or more compounds of formula (I): ##STR1## (wherein X represents a halogen atom and R represents a hydroxy group, an alkoxy gorup, a substituted or unsubstituted phenoxy group, an amino group, a mono- or di- alkylamino group, a phenylamino or benzylamino group which is unsubstituted or has one or two substituents on the benzene ring of the phenyl or benzyl moiety, or a 3-halo-2,3-diiodoallyloxy group). An anti-fungal composition contains one or more of these compounds in admixture with a carrier or adjuvant.
                            多种易受真菌侵蚀的有机材料(尤其是木材和基于木材的材料)可以通过处理来保护它们免受侵蚀,例如通过在表面上或浸渍时应用一个或多个式(I)的化合物(其中X代表卤素原子,R代表羟基,烷氧基,取代或未取代的苯氧基,
氨基,单或双烷基
氨基,苯基
氨基或苄基
氨基,其未取代或在苯或苄基的苯环上有一个或两个取代基,或3-卤代-2,3-二
碘丙烯氧基)。一种抗真菌组合物包含这些化合物中的一个或多个与载体或助剂混合。
