Physical barriers and bait toxicants: The Romeo and Juliet of future termite control
1991 - IRG/WP 1503
Soil chemical barriers are considered by some to be the most important technique for protecting buildings against subterranean termites in Australia (and elsewhere), providing a barrier against termite penetration. However, there is no such thing as a barrier that is 100 per cent +protective. And given the worldwide problems of using organochlorine termiticides, public awareness of chemical pollut...

Laboratory evaluation of chemicals as termiticides
1986 - IRG/WP 1293
Laboratory procedures are described for screening chemicals against subterranean termites. Fast-acting compounds with persistent termiticidal activity are identified in tests using a soil substrate, and slower-acting bait toxicants are evaluated in a series of tests using cellulose substrates....

Potential toxicants for controlling soft rot in preservative treated hardwoods. Part 4: Evaluation of combined diffusion and toxicity
1979 - IRG/WP 2129
A large number of inorganic and organic preservatives were evaluated as potential soft rot control chemicals, by their degree of inhibition of fungal growth after allowing them to diffuse through a 6 mm thick wood slab. The tests were inoculated with wood powder from soft-rotted CCA treated poles. Pentachlorophenol was unable to diffuse quickly through the wood slab, although formulations with hex...

Effect of fumigant residue in aerated wood blocks on the spore germination of decay fungi
1991 - IRG/WP 2382
Fumigants are increasingly used in several countries for remedial treatments of transmission poles to increase the service life. The present study was initiated primarily to test the remaining toxic effects of spruce (Picea rubra) wood, fumigated with chloropicrin (trichloronitro methane) or MIT (Methyl isothiocyanate) after long period of aeration, on the spore germination of decay fungi. This st...

An initial evaluation of the environmental impact of potential marine biocides
1978 - IRG/WP 441
Pilings and other structures in the marine environment are protected primarily by impregnation with creosote alone, or in combination with coal tar or waterborne preservatives such as copper-chrome-arsenate. Some of these materials are considered as possible ecological hazards and face an uncertain future; perhaps newly developed treatments to replace these conventional ones will pose different pr...

Potential toxicants for controlling soft rot in preservative treated hardwoods. Part 1: Laboratory screening tests using a filter paper technique
1977 - IRG/WP 290
Thirty-one miscellaneous formulations have been screened using a filter paper assay technique, for their efficacy in controlling the growth of Chaetomium globosum, Cephalosporium acremonium, and a mixed inoculum of finely ground soft-rotted wood obtained from preservative treated transmission poles. The formulations consisted of various organic compounds and inorganic preparations made from differ...

Bait box technique for remedial subterranean termite contro
1995 - IRG/WP 95-10115
The bait box technique, as described in this paper, was first used as a method to apply the dust toxicant, arsenic trioxide, to large numbers of aggregated subterranean termites. Over the last twelve years or so the technique has been refined, and in recent years, gained acceptance as an alternative subterranean termite control measure by members of the Australian pest control industry. This baiti...

The influence of drilling patterns on the distribution of toxicants from Polesaver Rods in hardwood poles
1994 - IRG/WP 94-30051
Polesaver Rods are solid rods of wood preservative that are used as a groundline maintenance treatment to control biodeterioration in hardwood transmission poles in Australia. The rods are inserted in holes that are drilled in a prescribed manner to distribute the toxicants into the critical groundline region of the poles. To determine the influence of drilling patterns on the distribution of toxi...

Potential toxicants for controlling soft rot in preservative treated hardwoods. Part 2: Laboratory screening tests using sawdust
1977 - IRG/WP 2101
A technique is described for the rapid screening of toxicants against microorganisms, represented by the brown rot, Gloeophyllum trabeum, and a natural inoculum from soft rotted wood. Sawdust, in this case from sapwood of Eucalyptus maculata, is pretreated with the candidate formulation and moistened before inoculation. Visual scoring of growth can be used to discriminate suitable candidates as ea...

Field evaluation of several bait toxicants for subterranean termite control: A preliminary report
1988 - IRG/WP 1376
Since 1983, field studies have been conducted to evaluate the effectiveness of several bait toxicants in reducing subterranean termite populations at the Chipola Experimental Forest in Florida. Tests with fenoxycarb (Ro 13-5223), Ro 16-1295, and Avermectin B1 indicated that fenoxycarb showed the most promise. Large numbers of presoldiers and intercastes have continued to occur in plots treated wit...

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...

Laboratory evaluation comparing three commercial termite baits based on chitin synthesis inhibitor (CSIs) against the subterranean termites Coptotermes acinaciformis (Froggatt) and Mastotermes darwiniensis Froggatt
2007 - IRG/WP 07-10625
This laboratory bioassay report describes laboratory evaluation undertaken to compare the efficacy, and palatability of Requiem®, Nemesis® and Sentricon® AG as candidate bait toxicants against the subterranean termites Coptotermes acinaciformis (Froggatt) and Mastotermes darwiniensis Froggatt. The laboratory bioassay results confirmed palatability and efficacy differences between the three comm...
