Enhanced biodegradation of cocopeat by soft rot fungi
1998 - IRG/WP 98-10276
Biodegradation of cocopeat (coir dust) was enhanced by the addition of nitrogen (N) fertilizer and inoculation with the soft rot fungus Chaetomium globosum. The N and fungally treated cocopeats had a greater percentage weight loss (27%) after 3 months compared with 7% weight loss without the added fungi and N fertilizer. In addition, their hemicellulose, cellulose and lignin contents were greatly ...

Intrigue Dust - A new method of eradicating subterranean termite (Isoptera: Rhinotermitidae) colonies
2001 - IRG/WP 01-10396
Arsenic trioxide is used by pest controllers in Australia to eradicate subterranean termite colonies. In 2000 Bayer Australia introduced Intrigue Termite Dust as a more environmentally acceptable alternative. Intrigue, containing 80% triflumuron, a chitin synthesis inhibitor, disrupts the moulting process in termites. Dusted termites return to the nest and pass around triflumuron via mutual groomi...

Laboratory evaluation of AC 217,300 as a termiticidal dust
1983 - IRG/WP 3247
Laboratory bioassays are described with the amidinohydrazone, AC217,300, a candidate termiticide to replace arsenic trioxide in termite control. When used as a dust and topically applied, AC217,300 was toxic to Coptotermes acinaciformis and Mastotermes darwiniensis. Although arsenic trioxide dust causes faster mortality in Coptotermes acinaciformis than AC217,300 dust, the latter has lower mammali...

Evaluation of literature on adenocarcinomas in wood workers
1997 - IRG/WP 97-50092
Occupational exposure to wood dust alone or chemically treated is suspected to be associated with an increased risk of developing adenocarcinoma of the nasal cavity, which in the general population is very rare; fewer than 10% of nasal cancer deaths are adenocarcinomas, which have an annual incidence of 1-2 per million. However, the epidemiological data available are not sufficient to make a defin...

Efficacy of triflumuron dust against Schedorhinotermes intermedius (Isoptera: Rhinotermitidae)
2000 - IRG/WP 00-30226
Insecticidal dusts have been used against termites for decades, with arsenic dust being the standard in Australia. While fair success over the years has been achieved against genera such as Coptotermes and Nasutitermes, Schedorhinotermes has been much more difficult to control. This genus has nests which are very difficult to locate and thus it is problematic to determine whether a treatment has b...

Laboratory evaluation of disodium octaborate tetrahydrate (TIM-BORÒ ) as a wood preservative or a bait-toxicant against the Formosan and eastern subterranean termites (Isoptera: Rhinotermitidae)
1991 - IRG/WP 1513
A no-choice bioassay indicated that termite feeding was significantly reduced when wood was treated with TIM-BORÒ at retentions of >3600 ppm and >900 ppm (w/w) for Coptotermes formosanus and Reticulitermes flavipes, respectively, and thus these wood preservative retention rates may be considered for these termite species. Results of a choice bioassay suggested retention rates of 450-1800 pp...
