Stady on the Control of Blue Stain Fungus and Moulds on Rubber Wood with New Wood Preservative TWP and Others

Four single chemicals and six formulations were tested in laboratory. The results showed that (1) in controlling blue stain fungus (Bot-ryodiplodia theobromae Pat), TWP is the best one in the test and its toxic limit concentration is at 1%, (2) in controlling mixed moulds (Trichoderma lignorum, Penicillum citrinum and Aspergillus niger), TWP is as good as NaPCP or MECT (or ANTIBLU 3738 or TCMTB + MBT). To prevent blue stain and moulds on rubber wood, the chemical treatment and testing method were also discussed.
