Testing of termiticides in soil by a new laboratory method with regard to Phoxim for replacement of chlorinated hydrocarbons
1986 - IRG/WP 1292
In comparison to chlorinated hydrocarbons insecticides of the compound classes organophosphates, carbamates and pyrethroids were tested according to an earlier described soil-test in the laboratory. The following termite-species were used: Heterotermes indicola, Reticulitermes santonensis and in addition Reticulitermes flavipes, Reticulitermes lucifugus, Reticulitermes speratus and Coptotermes for...

Application of roller-pressing method to the novel liquid impregnation treatment of green timber
2001 - IRG/WP 01-40198
A transverse compression technique enabled us to impregnate liquid into green timber through replacement of the free water in the timber with a treatment liquid without any critical physical damage to the timber by the roller-pressing method. The roller-pressing is supposed to remove free water the cell cavities and to concurrently introduce the treatment solution into green timber in the treatmen...

Effects of the delay in the beginning of treatment on absorption and distribution of water-soluble salts in posts treated by sap-replacement method
1992 - IRG/WP 92-3719
One of the most important matters in green wood treatments, such as sap-replacement method, is knowing the longest time available for beginning treatment without losing efficacy. In this paper, the influence of this factor on absorptions and distribution of the preservative into the wood is analized. Tree start-up times were first chosen: 3-6 hours, 48 h and 120 h after being cut down. The treatme...

Copper-octanoate - a potential reference preservative replacement for CCA in field test standards?
2022 - IRG/WP 22-20688
Finding a CCA reference replacement for use in standardised test methods is of high priority since this chemical is being phased out and may in the near future be banned also for experimental and approval purposes. In this paper we assess the possibility to replace CCA reference preservative with an historical copper octanoate product. There is a huge amount of lab and field test data available fo...
