Fungicidal combination products
1987 - IRG/WP 3426
Due to the increased pressure on some of the established fungicides used in wood preservation, possible alternative products become more interesting. The requirements for new chemicals are mainly lower toxicity and greater environmental acceptability. However the efficacy to target organisms should be as good as that of the currently used ones, preferably better. A possibility for progress in this...

Appearance of PEC-treated poles in service
1985 - IRG/WP 3323
Poles treated with conventional high temperature creosote (HTC) are banned for use in Australia by the major union handling them. Pigment emulsified creosote (PEC) is an acceptable alternative because it provides much dryer and cleaner commodities than does HTC. More than 5000 poles have so far been treated with PEC and many are being installed into service. The brown pigmented PEC 30 B has given ...
