| Abstract: | A method is described in which test blocks with envelope preservative treatments can be challenged by selected test fungi previously established on an untreated feeder block. The progress of the test fungus through the treated zone is monitored using novel baits or sensors inserted in holes drilled into blocks to within predetermined distances of the face being challenged. Preliminary results show the method to be discriminating. Three-minute immersion treatment with 5% pentachlorophenol retarded colonisation for a longer period than 1% tri n-butyltin oxide, particularly when penetration was in the tangential direction. |
