橡胶木防霉防蓝变药剂的现场试验

现场试验的结果表明，F1/F2混剂处理的橡胶木圆盘、单板的防霉及防蓝变效果较F2及五氯酚钠要好。F1/F2及五氯酚钠各制剂处理的板材基本上无霉菌感染及蓝变。在真空加压试验中，0.02?可保持橡胶木板材在气干过程中12天基本不霉变及蓝变，但对白霉的防治效果较差；0.0094?与0.018?混合剂可保持像胶木板材气干时15天不长霉或蓝变，增加F1/F2的浓度可能会在气干时保持更长的时间。

Pilot Test of Anti-sapstain and Anti-mold Formulations on Rubberwood

The mixture formulation of chlorothalonil emulsion (F1) and mixture of chlorothalonil emulsion and other fungicide (F2) was more effective than F2 or sodium pentachlorophenol (NaPCP) alone in controlling stain and mold of rubberwood ( Hevea brasiliensis ). In pilot test, the sawntimber treated with each formulation of F1/F2 and NaPCP was not infected with stain and mold. In vacuum pressure treatment test, the result indicated that F2 could prevent the treated timber for 12 days from stain and mold except white mold; and the mixture of 0.0094% F1 and 0.018% F2 could keep the treated timber for 15 days from stain and mold in air drying procedure under the above concentrations. The higher concentrations of F1/F2 might prevent the treated timber for longer time from stain and mold.
