Factors affecting decay rates in a fungus cellar II
1986 - IRG/WP 2259
Tests were initiated to investigate the influence of various factors on the decay rate in a "Fungus Cellar". Birch and pine stakes treated with chromated copper arsenate and didecyldimethyl ammronium chloride, as well as untreated control stakes, were incubated in two soils in a Fungus Cellar test and installed at two field sites for comparative purposes. The visual rating vs actual stake weight l...

Developments in unsterile soil soft rot testing
1984 - IRG/WP 2210
Two unsterile soil test methods, the soil burial technique and a method using vermiculite burial with soil inoculation, were compared using different soils to determine their effectiveness in evaluation of wood preservatives against soft rot. Isolation of fungi and microscopy of decayed wood indicated that both methods produced accelerated soft rot attack in treated and untreated birch. Vermiculit...

Termite resistance of treated wood in an above-ground field test
1985 - IRG/WP 2241
A field test method has been developed for evaluating the susceptibility of wood products to termites in protected situations above ground. In this method fungal attack on the wood products is minimal, though decay has been observed in conjunction with termite attack in some specimens. Preliminary results from exposure of replicate wood samples treated with preservatives in Florida to Reticuliterm...

Termite resistance of treated wood in an above-ground field test
1986 - IRG/WP 1300
This paper provides an update on the results from an above ground field test evaluating the effectiveness of wood preservatives against subterranean termites. Results for the one and two year inspections of treated southern pine sapwood exposed in Hawaii to Coptotermes formosanus are presented. Chromated copper arsenate is providing excellent protection as is the pyrethroid deltamethrin. Borate an...

Factors affecting decay rates in a fungus cellar
1985 - IRG/WP 2242
Birch and pine stakes treated with chromated copper arsenate and didecyldimethylammonium chloride were incubated in two soils in a "Fungus Cellar" test. At three month intervals, sets of stakes were inspected and assigned visual ratings or removed from the soil beds for weight loss determination. Preliminary results after nine months exposure have shown differences in the decay rates between birch...
