Termite and decay protection - A superficial barrier field test
1983 - IRG/WP 3257
Samples of Pinus radiata were given a superficial barrier treatment and installed in the ground at two sites for five years to observe termite and fungal attack. The three best treatments of the series were Denso petroleum tape, Koppers hot dip tar enamel, and Arquad 2C/75 alkyl ammonium compound. As new fungicides and insecticides become available they are being added to the test using the same s...

Field testing of alkylammonium wood preservatives
1983 - IRG/WP 3248
The field test performance of five alkylammonium wood preservatives is described. The relative effectiveness of three unmodified formulations was determined by calculation of a Performance Index. Of the three, didecyldimethylammonium chloride was found to be superior to octyldecyldimethylammonium chloride, and both were more effective than alkyltrimethylammonium chloride. However, none were consid...
