霉菌和蓝变菌是橡胶木和竹材变质的主要原因之一。八种防霉荆对上述木竹材霉菌及蓝变菌的毒性试验结果表明：祛霉乐防霉剂对霉菌的最低抑制浓度为２～１０ＰＰｍ，和ＭＥＣＴ相当，对蓝变菌有特效，防治橡胶木或竹材霉菌和蓝变菌的最低有效浓度为０．２％，可替代五氯酚钠和进口防霉剂。 Mold and blue-change bacteria are one of the major causes of the deterioration of rubber wood and bamboo. The results showed that the minimum inhibitory concentration (MIC) of fungicide against fungi was 2 ~ 10PPm, equivalent to that of MECT. It had the special effect on blue-change bacteria and the control rubber The minimum effective concentration of wood or bamboo molds and blue-green bacteria is 0.2%, which replaces sodium pentachlorophenol and imported fungicides.
